Elementary pre-service teachers working in mathematical borders

Using the border metaphor to portray the common separation between school mathematics and students’ everyday lives, this manuscript describes the processes that a group of elementary pre-service teachers (PSTs) have experienced to learn about their students and bridge these borders. Content analysis of mathematical activities and PSTs' reflections developed in a mathematics teaching methods course reveals that although they asserted that the process of developing bridges between mathematics and everyday experiences has transformed their self-concept and confidence in mathematics and teaching, they mostly use their own knowledge and experience to develop these tasks rather than from their students’. Possibilities to generate more genuine ethnomathematical approaches are discussed.


Introduction
Acknowledging children's linguistic, intellectual, cultural and social resources is deemed as central in the process of developing an educational environment that is inclusive of students' experiences at home and in their communities (MOLL, 1992). In mathematics education, besides considering children's funds of knowledge, it is important to include open tasks offering students multiple ways of engaging in mathematics, as well as to make sense of these tasks by engaging in mathematical meaning-making activity (LESH et al., 2000;NGACBP, 2010). Integrating these perspectives in the preparation of pre-service teachers represents both a great potential and a challenge. This paper describes Ethnomathematics as an important approach in teacher preparation to support this link, since Ethnomathematics represents a "way that members of various cultural groups mathematize their own reality because it examines how both mathematical ideas and practices are processed and used in daily activities" (D' AMBROSIO & ROSA, 2017, p. 288). More specifically, this manuscript describes the challenges and affordances that a group of pre-service teachers (PSTs), participating in a mathematics teaching methods course, faced creating and developing tasks that were sensitive to their students' culture, language, interests and experiences.
The analysis of PSTs' work on ethnomathematical approaches provides an insight of how PSTs' are bridging children's funds of knowledge and mathematics during their design of ethnomathematical activities.
Ethnomathematics is a term introduced by Ubiratan D'Ambrosio (1991) to describe the techniques used to explain, understand and cope with reality in order to survive across diverse communities. Ethno relates to the members of distinct groups identified by cultural traditions, codes, symbols, myths and specific ways of reasoning and inferring (D'AMBROSIO, 1985). As Ethnomathematics centers on the mathematizing of frequent activities in specific communities (D'AMBROSIO & ROSA, 2017), such stance highlights mathematics as a cultural practice existent in human activity and challenges the perspectives that present mathematics mainly as a Western -Roman, Greek -knowledge, commonly taught at school.
An ethnomathematical approach helps us understand mathematics from a wider perspective than traditional school mathematics, seeing mathematics as a human act. As a result, Ethnomathematics can help us renovate the way we teach mathematics (LANGE, 1996;D'AMBROSIO & ROSA, 2017). In mathematics teaching and learning, Ethnomathematics helps us: expand, affirm and redistribute mathematical authorship and empowerment; draw from and expand resources to teach and learn mathematics; recognize and challenge spaces of marginality of knowledges of many communities; and strengthen the relationship between learners and mathematics (AGUIRRE, INGRAM-MAYFIELD & MARTIN, 2013;KOKKA, 2015).
Such approach should "perpetuate and foster -to sustain -linguistic, literate and cultural pluralism that are part of schools" (PARIS, 2012, p. 93). Thus, when students and teachers use their real world as a starting point for conceptual development, mathematics teaching and learning become more complex (LANGE, 1996) as they also become doers of mathematics (NCTM, 2000) by engaging in problem solving, multi-modal representations and communication to develop mathematical meaning making and mathematize through their own perspectives (NGACBP, 2010;FREUDENTHAL, 1973).

Context of the Study
This study includes the work with PSTs in a mathematics teaching methods course within a teacher-preparation initiative named TECLA (Teacher Education Collaborative in Language Diversity and Arts Integration) project. TECLA project is the result of the collaboration of seven professors in a United States (US) southwestern university across two different colleges and three different departments. Professors worked with the group of PSTs at different times along the three semesters that PSTs spent in TECLA as part of their Elementary Education undergraduate degree program.
The project focuses on a collaboration process among the professors that designed the program structure for the PSTs by integrating the content of their courses and field experiences.
This collaboration is also extended to the relationship developed between the Cooperating Teachers at the hosting school and the PSTs planning and co-teaching since the first day of the PSTs' field work. There were also an Arts and Curriculum teacher and a graduate student, who collaborated with the Cooperating Teachers, PSTs and professors, bridging together the work of everyone in the project and guaranteeing the extended integration of all activities in the project.
Although the project's general approach relates to an Arts-Integration (FALTIS, 2019;MARSHALL & DONAHUE, 2014), at the center of there is a social-justice goal that focuses on the linguistic and cultural diversity of the students' background at the hosting school.
The project hosted at an Elementary School, La Montañita, which is a community school that has Spanish-English, Navajo-English bilingual programs and welcomes a great diverse student population. According to the school district data, this school includes students who are 86% Hispanic, 7% American Indian, 3.5% African American, 2.6% White and 0.8% Asian. Additionally, a great influx of refugees and immigrants and also languages characterize students' population at this school. The PSTs' program in TECLA project is described in Table 1 below.  (STEIN et al., 2000).
This curricular structure was aligned with the generative topic supported by TECLA and the course content integrated language and culture perspectives as follows. In the first module: Nevertheless, once PSTs engaged with these integrated perspectives, they started making clear connections across course modules and in their teaching practices construction they collaborated with each other and encouraged peers to incorporate children's thinking, language, funds of knowledge, self-perception in mathematics and problem-solving strategies. As a result, PSTs helped me to realize that in a mathematics-methods course the focus is on children -who they are, where they come from, what they care about, what they know, what is going on around them. This is the essential foundation of all academic and pedagogical content knowledge for teaching mathematics.

Mathematics Teaching, Funds of Knowledge, and PSTs' Preparation
Investigations about students' funds of knowledge highlight the relevance of an education that actively includes students' community, backgrounds and language in the teaching and learning of school contents and languages. Funds of knowledge (MOLL & GREENBERG, 1990) include "the knowledge base that underlies the productive and exchange activities of households" (MOLL & GONZALEZ, 2004, p. 700). Funds of knowledge are not possessions of people in the family; instead they are "part of what people do in activities" (MOLL, 1992, p. 222); they refer "to the content and the social relationships that facilitate the exchange" (p. 231). Such knowledge and social relationships are flexible and adaptive, so they can be mobilized across contexts and activities, including mathematics learning and teaching (GONZÁLEZ et al. 2001;MOLL & GREENBERG, 1990;MOLL, 1992).
Students' funds of knowledge are linked to pedagogies valuing diverse students' life experiences and communities which were deemed from deficit views. Culturally Relevant Pedagogy (CRP) is defined ''as using the cultural knowledge, prior experiences, frames of reference and performance styles of ethnically diverse students to make learning encounters more relevant and effective for them'' (GAY, 2000, p. 29). CRP encompasses a process through which all students have the opportunity to experience academic success, develop and/or maintain cultural competence and develop a critical consciousness through which the status quo of the current social order is challenged (LADSON-BILLINGS, 1995). CRP perspectives have evolved into complex constructs that acknowledge societal power structures, so that the emphasis is placed on an integrated and sustainable development of cultural and academic competences of students: The term culturally sustaining requires that our pedagogies be more than responsive of or relevant to the cultural experiences and practices of young people -it requires that they support young people in sustaining the cultural and linguistic competence of their communities while simultaneously offering access to dominant cultural competence (PARIS, 2012, p. 95).
Several approaches in mathematics education specifically addressing the link between

Aguirre (2012) suggests a Culturally Responsive Mathematics Teaching (CRMT) approach
with two main goals: (a) students' development of mathematics thinking and (b) equity in mathematics classroom. As so, for the implementation of a CRMT approach teachers need to develop specific pedagogical knowledge, dispositions and practices that mobilize students' funds of knowledge, nurture their mathematical thinking and promote social justice in mathematics education.
In consequence, this study's theoretical framework is founded on the explicit acknowledgment of the participants' linguistic, intellectual, cultural and social knowledge in mathematics education. For example, Moschkovich (1999) recommends that when working with Latinx 1 students, mathematics teachers should: (a) honor the diversity of Latinx students' experiences, (b) know the students, (c) avoid deficit models, and (d) provide opportunities for mathematical discussions. Regarding the preparation of PSTs, it means that they need to engage in an explicit work and understanding on how to bridge students' funds of knowledge and mathematics. This means that PSTs need to work at the borderlands or liminal spaces of thinking about both their students and mathematics, linkage which is mediated by PSTs themselves.
Thus, who PSTs are is a crucial element to this linking process. PSTs need to work as Nepantler@s. Nepantler@s, according to Anzaldúa, travel in many disciplines to "invent holistic, relational theories and tactics enabling them to reconceive or in other ways transform the various worlds in which they exist" (KEATING, 2006, p. 9) to support bridges between students' lives and school. Only a careful ethnographic analysis of the transmission of these resources at home and their application into school instruction will support a convincing demonstration of children's knowledge in their academic performance (MOLL, 1992). Moreover, besides PSTs' inclusion of children's funds of knowledge, in mathematics education designing open tasks is also important since they offer students a context to engage with mathematics, to make sense of it and engage in mathematical activity (LESH et al., 2000;NCTM, 2000;NGACPB, 2010).
In my opinion, it is through the inclusion of the learner's prior perspectives that school mathematics becomes integrated with the learner's knowledge basis. In mathematics education several approaches have targeted the link between school and community mathematics; for example, Ethnomathematics (D'AMBROSSIO, 1991), Realistic Mathematics Education (RME) approach (WEBB, VAN DER KOOIJ & GEIST, 2011) and mathematization processes (GRAVEMEIJER, 1997). In RME, "students connect prior knowledge to new mathematical representations, concepts and skills.
As a result, a more robust way of knowing and doing mathematics is constructed from the student's perspective" (WEBB, VAN DER KOOIJ & GEIST, 2011, p. 48). The realistic portion does not necessarily imply connections "with real world contexts, but it is related to the emphasis that RME puts on offering students problem situations which are imaginable" (WEBB, VAN DER KOOIJ & GEIST, 2011, p. 48) or realistic in the view of the students. When students engage in mathematical tasks that blur borders and become relevant to students and their social interactions, then tasks promote the emergence of a "zone of mathematical practice" (GONZÁLEZ et al., 2001).
Holistically, the conceptual framework in this study centers on how PSTs mathematize their own reality and their students' reality in order to promote mathematical tasks that overcome the borders that school mathematics often places between students' daily life and mathematical 188). Nonetheless, the authors describe that the overlap of contexts created potential connections across contexts for PSTs to promote better connections between the community and school mathematics.

Methods and Data Sources
Content analysis process is a "technique for making inferences by objectively and systematically identifying specified characteristics of messages" (HOLSTI, 1969, p. 14). In order to explore the processes of integrating children's funds of knowledge with school mathematics, as well as how the 22 PSTs understood these processes as part of their mathematics teaching practices with bilingual and bicultural students, I used content analysis.
I qualitatively analyzed the first-semester PSTs' assignments, such as module reflections, the community-based lesson (CBL) paper and their journal reflections, taken during course classes and fieldwork experiences, as well as the instructors' field notes. The CBL paper was developed by PSTs through interviews with their students and observations of them during class and breaks.
Some of them also consulted the cooperating teachers.
The initial themes of the analytical process were related to the content either of the task/problem that PSTs developed or their reflections linking students' funds of knowledge with mathematics teaching and learning. A second level coding yielded overarching themes that are described in this paper and which are illustrated through examples that come from PSTs' work.
While PSTs' gender did not represent a major variable for these patterns, PSTs' cultural and linguistic backgrounds had a more significant but still not consistent role across cases.

Results
Three themes permeated PSTs' transformative knowledge and actions in mathematics education: (a) finding links between students' funds of knowledge and mathematics-PSTs' investigations about their students' funds of knowledge revealed various potentially-rich contexts and practices that could support links between school and community mathematics; (b) developing these links based on PSTs' personal experiences-while some PSTs acknowledged the identified contexts or practices related to the students' funds of knowledge or community wealth, PSTs used their ideas and experiences to present these links; and (c) developing these links by mathematizing student-centered experiences-PSTs used student-relevant potentially rich-mathematical contexts as sources for students' mathematical investigations and problem solving, The inclusion of students' experiences linked more directly students' personal identities and funds of knowledge and to seeing themselves as doers of mathematics. Each of these themes is described below with examples of PSTs' work.

Finding Links Between Students' Funds of Knowledge and Mathematics
Through interviews and classroom activities, PSTs' developed an inquiry about their students' funds of knowledge, which served as a foundation to develop mathematical tasks.  Marta: This was very surprising to me, but I was able to see firsthand some of these important differences. A girl in my assigned classroom is new to the United States from Ecuador, and while I was helping her with math I wrote a 7 (uncrossed) and she read it as a one, I am still getting used to the way she writes her 1s, which, to me, look sometimes like 7s. Respect means that teachers will not negatively view the knowledge (or funds of knowledge) that students bring to the classroom, but will instead use them to aid the education process. Respect also means eliminating "the notion that methods used in schools in the United States are inherently better" (Perkins and Flores, p. 124).
PSTs' reflections on students' funds of knowledge were extended, not only through readings, but also through their own experiences with their students. These reflections included also the process of devising and designing responsive mathematical tasks. Andrea reflected on how she envisioned the possible mobilization of students' funds of knowledge in mathematics by addressing beyond the content of her students' funds of knowledge: Andrea: The perfect way to motivate students and create a complexity of literature is by learning how to mobilize funds of knowledge in a classroom. The way I plan to mobilize funds of knowledge in my class is by pulling each student own experiences to help them like math. For example, if a student comes from a family where they own a business then this child must know some type of math. I can relate back to him and say for example, "Well Johnny you know how your dad owns a store, how does he add up all the money in the cash register? Maybe you can help us teach addition today." Another great idea would be to invite Johnny's dad into the class as a guest speaker so that he can briefly explain how he conducts such task. By creating social interactions, funds of knowledge can easily be mobilized to benefit our students.
Andrea's argument supports the notion that funds of knowledge are not simply related to "what" or the content of an activity in the life of a student, but also to the kind of social relations that both generated and mobilize those ideas. In this way, empty uses of "whats" would be insufficient if they are not supported by social interactions that nurture them to get into the new context of learning school mathematics.
Although PSTs developed stances about how they would address the bridging of student experiences and mathematics, PSTs' prior experiences in mathematics also affected how they conceptualized a mathematical task. Then, the levels of risks they took to mathematize apotentially-rich-mathematical activity related to students' funds of knowledge was constrained by how PSTs self-received in relation to mathematics. These relations were informed by their experiences with school mathematics. Viviana: I struggled a lot. Information just did not stick. Math was the only subject that I did not excel in, which made for a very sad, young little girl. I felt unintelligent and that my input, opinion or thoughts were not necessary or needed. Instead of being the student who felt confident to raise her hand and answer questions, be the Math group leader, or the student who was happy to see her test scores; I was the one who sat passively year after year, dreading Math class, being so nervous the night before a test that I could not sleep.
Experiences such as Viviana's were not uncommon among PSTs. These situations highlight that at the borderland of linking school and community mathematics, PSTs grapple with more than just establishing a link. They need to face who they think they are in relation to mathematics. Furthermore, as these borderlands also include the linking of cultural practices, the connection that PSTs noted between their experiences and their students' was affected by their perceived connections between self and the students' community. It is further described next.

Experiences
As PSTs developed of mathematical tasks related to what they had learned about their students' funds of knowledge, these tasks were not always directly linked to the students' but rather PSTs' experiences. For example, some PSTs identified music and sports as important activities related to their students' funds of knowledge; however, during the development of mathematical tasks some PSTs drew from their own funds of knowledge and experiences instead of from their students'. The work of Daniel and Diane represent this situation.
They made use of their prior experiences and knowledge to link what they found about their students' funds of knowledge. Daniel -a PST who enjoys music very much, after realizing that the students he interviewed enjoy music also -developed a task linking music and mathematics. He worked in Kindergarten and needed to teach about patterns. Daniel linked the concept of patterns with music through a task of using pattern blocks and linking each shape to an action or sound, so that the shapes could be sequenced in different patterns to create patterns of shapes and rhythms or 'music'. Daniel: The activity will have students to understand what a sequence is. For example, I will say clap, clap, legs, legs, feet and feet. I will repeat this sound sequence twice and students will try to remember this pattern of counting. Another example could be feet, clap, clap and feet, also repeated twice. This task allows students to learn the importance of counting in the rhythm of songs. Notice that if one student forgets to count the sequence correctly, he will lose the rhythm of the song. However, it doesn't mean that he can't figure out the sequence in the right order after he got lost.
When Daniel implemented this task, he modeled to students how to create rhythms.
Students were able to decide the arrangement of the shapes and what they represented. In this way, students "wrote" different patterns and rhythms. This task promoted student participation and motivation in pre-algebraic thinking. While this task related to music, the task itself did not directly align to students' experiences with mathematics, but to Daniel's adaptation of musical rhythm represented through shapes.
In the case of Diane, she found out that her students like soccer, used the idea of soccer = clap = feet (stomp) = tap on lap not to create a soccer embedded mathematical task. Instead she developed a task/game in which students imagined that they were playing soccer and annotated a goal by responding to a question related to a mathematical operation, like "what is 5 times 5?". Another PST also used a golf game board in which students could move along the board by responding to subtraction operations. In the two cases students did not engage in the games as expected by PSTs. It is not sure whether students viewed the tasks as related to the sports they like.
Some PSTs could not find ways to link more directly their students' funds of knowledge with mathematics; and instead they developed mathematical tasks that were superficially related to funds of knowledge and required low levels of cognitive mathematical reasoning. This lack of social and mathematical authenticity relates to the fact that the activity of playing soccer or golf is not the same as playing a board game that relates to golf or soccer; even the mathematics involved in soccer does not relate to answering to basic facts fluently. A board game is another activity that might not always be significant to the students. Funds of knowledge are to be transformed into meaningful activity in mathematics, these include activities people do in a community and to the content and the social relationships in those activities (GONZALEZ et al., 2001;MOLL, 1992).
It is not only to be responsive or relevant to a cultural content, experiences or practices of a community, a culturally sustaining approach requires to sustain the cultural and linguistic competence of the communities while simultaneously offering access to academic competence (PARIS, 2012). This situation makes one wonder about what needs to happen so that PSTs find relevance between their students' funds of knowledge and their own? How does this connection facilitate the process of establishing these nuanced links? What is the actual issue? Drake and Norton-Meier (2007) have found rigid boundaries between funds of knowledge and academic content. Daniel was able to find links between music and mathematics due to his familiarity with both, but he was not as successful in bridging this familiarity with his students'.
Diana on the other hand was not familiar with soccer but instead she was more familiar with game boards, which is what she used. She also could not find a direct mathematical connection to the game, so she resourced on basic mathematical facts. These ideas speak to situations when adaptations of mathematical problems to make them culturally responsive by simply changing some names or words in the word problem. This adaptation focuses on what without acknowledging the social dimension of those activities that characterize the meaningfulness of the activity to the community.
Further, familiarity with mathematical content and what helps students learn mathematics are important knowledges that can better support PSTs' development of mathematical tasks. Diana reflected on these points in her following assignment as she focused more on the mathematics and less on the cultural responsiveness of a mathematical task. It takes explicit reflection and experience with who students are and their ways of learning. More studies exploring bridges between PSTs' funds of knowledge and their students', especially how PSTs cope with these differences as well as the quality of connections established between the mathematical task and the activity related to the students' funds of knowledge are needed.

Experiences
The relevance of a Culturally Responsive Mathematics Teaching (CRMT), which is based on the need of a genuine exploration of students' funds of knowledge; especially of those from minoritized groups, was evident to all PSTs. This relevance had different connotations. Some PSTs have had personal experiences that informed them directly about the importance of addressing student's diversity in the teaching of mathematics. PSTs wanted to make a difference and effect changes in education, so that education would be more inclusive of students' experiences, cultures and languages. Laura's comment extends this argument beyond mathematics education: Laura: This is something I always struggled with in school because it felt like in every class the material always focused on my white counterparts' lives and it was just something that made me not interested in school. However, one thing I might add and caution future teachers, even myself, is to not try and make the problem without finding out about students' lives, meaning don't just add a problem about making tamales because you have a Latino student and assume he makes them on his spare time.
To Laura, knowing students is of great importance to guide teachers' teaching and curricular adaptations away from essentialist cultural perspectives based on their students' backgrounds. Instead, Laura called for a more authentic process of getting to know her students.
Laura's insights derived from her own experiences as a Latina student. Her familiarity with this issue granted her with awareness about important aspects of being a teacher with this student population.
Such stance has been documented with Chicana teachers whose identities and previous experiences contribute to how they define their professional role in relation to students from a similar cultural minority background as well as their awareness of the challenges that minoritized students face (GALINDO, 1996). As a result, Laura's adaptation of mathematical tasks, drew from non-essentialistic students' funds of knowledge of Latinx students. She worked with a group of girls mathematizing formations and positions for a cheerleader presentation. Students used mathematical activities such as measuring time and designing symmetric formations Brisa's teaching experience speaks to a similar situation. Nevertheless, as she was working on perimeter and diameter of geometric shapes, she wanted her students to apply and reinforce such concepts and ideas. Looking for challenging experiences for 5 th graders and having mathematical explorations outside of the classroom, she noted maple trees around the school playground. Furthermore, aware of students' funds of knowledge reports on exploring geometry in nature and that students needed to study plants in Science. She developed a task -'how much a maple leaf measures?' -, in which students had to find the area and perimeter of a leaf.
To solve the task, students had to use unconventional unit measures. When, Brisa asked how they would measure the leaf's perimeter and area, students resourced to using the squares on a sheet of grid paper as unit of measurement. Arguing that the edge or margin of the leaf is the perimeter, and the area is the lamina or blade of the leaf. Figure 2 below presents an example of students' work on this task. Note that students differentiated between the two-dimensional aspect of the measuring of area as it covers entire squares, while the perimeter related only to the length of a side of the square. In a personal reflection about teaching field experiences, Brisa mentioned: "I enjoyed my math methods class because it was at La Montañita. It gave me a real feeling of being in a classroom with kids that put myself out of my comfort zone". In Brisa's reflection, we observe how PSTs' self-concept in mathematics serves as a starting platform in the borderline to start developing sensitive links between the students' ideas and mathematics. Further, as Brisa took risks and engaged in developing mathematical experiences more tangible and meaningful for her students, students participated more enthusiastically and genuinely to the point that they learned and showed their learning and desire in completing the task in the best way possible. In turn, Brisa's confidence in doing and teaching mathematics also increased. Thus, I think that as we attempt to blur boundaries between school mathematics and our students, we also blur those boundaries for ourselves as mathematics teachers. Both students and Brisa remarked feeling more competent in mathematics by engaging in such application of mathematics.
Another daily activity that was very common among students from the school was the watching of TV programs. However, the pool of TV programs that they had watched was very This problem presents multiple entry points to solve it, but it also requires a high level of cognitive reasoning because students are engaged in "doing mathematics" (STEIN et al., 2000).
Students mathematized the division of the chocolate bar by either dividing it into fractions or using the already embedded structure of this composite unit. Although the mathematical concepts embedded in this problem were rich, the content and social interactions of the problem also showed the type of jokes and interactions that exist in El Chavo program.
This speaks that the content of the program was left and used as it is, but it served as a context to creating a problematic situation that resembles common situations in the practice or TV PSTs had similar experiences to those from Hispanic students they interviewed.

Concluding Remarks
"Successful cases of integration are characterized by 'transformative practice zones' that 'provide spaces to share and listen to others' ideas, visions and commitments, and to build relationship in collaboration across disciplines" (BRESLER, 2003, p. 24). I learned through the PSTs I worked with that when we take risks working to blur the borders between mathematics and students' experiences, we also blur those borders for and within ourselves. Therefore, we are contributing to a renovation of how we see ourselves as mathematics' doers and especially as mathematics' teachers. A stronger and closer relationship with our students and mathematics is revealed in our eyes and in our heart, just as Brisa described. Moll (1992) and colleagues have argued that the ultimate goal of these innovations "depends on when and how teachers become part of the decision to initiate change" (p. 229). This study describes an evolving commitment of PSTs towards educational changes that place students' own knowledge at the center of mathematical education. Although PSTs' efforts to support their students' mathematical learning in their students' funds of knowledge were evident, it was also clear that in the process of developing the mathematical tasks PSTs' funds of knowledge played an important role too. Most of the PSTs (20/22) were actually able to bridge school mathematics, realistic mathematics applications and students' funds of knowledge.
At a certain point, PSTs found some kind of familiarity during the design of the mathematical tasks because their prior experiences as students somehow resembled their students' activities, although the content could not exactly be the same. For example, Daniel's familiarity with music, not necessarily the same type of music of his students like, helped him to see potential links between sounds, rhythm and mathematical patterns.
Nevertheless, some PSTs with least familiarity with students' funds of knowledge faced greater challenges trying to establish these links. They designed tasks with less realistic applications and with lower levels of cognitive reasoning (STEIN et al., 2000). Like Aguirre, Zavala & Katanyoutanant (2012), questions related to these shortcomings should be explored in relation to pedagogical issues. Perhaps, it might be helpful for PSTs' to engage in a more ethnographic approach to understand the diverse community practices and activities that are unfamiliar to them, so they can get better ideas to establish these links.
Mathematics methods courses could help PSTs to develop this type of awareness and also strategies to develop mathematical tasks that are inclusive in terms of their students' funds of knowledge. One way to establish connections with unfamiliar activities perhaps could be through engaging in an Extended Related Activity (see LÓPEZLEIVA, 2014) that could help us to become more familiar with the diverse community activities and mathematize them.
Another way to get to know students better (MOSCHKOVICH, 1999) could be by developing a mutual learning process between PSTs and students they work with. That way PSTs learn about their students through the development of a closer relationship with one student or more. This resembles Moll's household visits and interviews with parents, so that PSTs could learn more about community practices and knowledges.
The goal of Mathematics Teacher Education is to take an ethnomathematical perspective, so PSTs can learn about their students' funds of knowledge. The first step would be to identify a border that needs to be overcome and blur (KEATING, 2006) through 'transformative practice zones' (BRESLER, 2003) of working and the development of closer relationships with students.
We need mathematics teaching practices that recognize and challenge spaces of marginalized knowledges of many communities; and strengthen the relationship between students and mathematics (AGUIRRE, INGRAM-MAYFIELD & MARTIN, 2013).
We need mathematics teachers -and mathematics teacher educators -critical and smart enough to notice and identify borders, but most of all, sensitive and creative enough to make breakthroughs that promote knowledge and relationships among students, teachers and mathematics.
Furthermore, PSTs' understanding of funds of knowledge was also crucial in the development of empathy and commitment helping them to integrate students' identities in mathematics teaching. PSTs' understanding of both concepts and their relevance was promoted through a system that transcended the mathematics methods course and reached a system of support provided by the TECLA program through the Literacy courses and the fieldwork seminar.
This confirms that an integrated approach in PSTs' preparation provides a rich conceptual, pedagogical and practical context to teaching and learning mathematics.
