Many students shown learning disabilities characteristics but neither their parents nor teachers notice about them. Because of that, they continue to have poor performance on their achievement at school. This is a very pity condition since every student has hidden potentials which need to be blossomed. The situation could get worst when people around them start to give them bad label, for instance lazy or stupid students. Those labeling will not help students to meet their full potentials. Instead of complaining, parents and teachers should know more on how to assess students’ learning problems. There are psychological and behavioral characteristics of learning disabilities which can be studied easily by everyone. First, you may start from dyslexia problem that very common on children. Student with dyslexia have problems with writing, reading, and understanding conversations. However, not every student who shown those symptoms could be categorized as dyslexia. The diagnosis will be valid once it is conducted by professional psychologist. But, teachers and parents could be the first one to notice the learning problems before go seek for professional helps. Still from dyslexia, students who got this condition will have difficulty on reading or writing. Of course this situation will not be a problem if we talk about kindergarten or first year students. The reading or writing difficulty will be a problem when the students have met certain ages, where they should know how to read and write well. Another problem which could be found in school is dysgraphia. Even though it has same difficulty to write condition just like dyslexia, dysgraphia is slightly different. Students with dysgraphia could be noticed easily from their bad handwriting. If the handwriting could be improved better, that will not be better. But if the contrary condition happens, those students need to meet professional assessor to get valid diagnosis. The other dysgraphia characteristics are: strong dislike with drawing and/or writing and also trouble with grammars. Students with dysgraphia problems have difficulty to write down their ideas as well. When writing lessons come, those students will lose their interest quite fast. They need to say the words out loud when writing. Although mathematic consider as one of most difficult lessons, there is a condition when people really cannot understand this lesson. That condition is named dyscalculia, where people cannot understand the basic concepts of arithmetic, for instance negative-positive numbers, number lines, and many more. If you know those mentioned key characteristics of learning disabilities, you can help the students better.
