Math books have "frequent references to social benefit programs introduced by Chávez". In history books, there is only one page explaining Venezuela's last 40 years of democracy while there are over twenty pages devoted to Chávez. According to Maria Teresa Clement, Secretary of Communication of the Venezuelan Federation of Teachers, the changes to the history books "revolves around the role played by a single president [Chávez], as if the previous historical record was irrelevant". Other books also include anti-capitalist attitudes and show "economic sectors of the country and the U.S. as the great enemies of the country". One text "ensures economic groups launched a coup with the help of United States sent ships to invade Venezuelan waters". In 2014, an assembly of teachers on the islands of Margarita and Coche demanded an end to "the indoctrination of children by educators" at the regional and national level, claiming that the days between the 5 and 15 of March were aimed "to worship former late President Hugo Chávez". The president of the Venezuelan Chamber of Private Education, María Teresa Hernández claims that Resolution 058 by the government is "unconstitutional" and that it "seeks for colectivos with political projects of the ruling to be directly involved in public and private schools" in Venezuela. She continued saying that schoolchildren are "very easy to manipulate" and need to develop political beliefs on their own. In "Chávez's Children: Ideology, Education, and Society in Latin America", Manuel Anselmi explains that "To get an idea of the importance of Bolivarian propaganda as a source of alternative political education one can use the testimony of Hugo Chávez himself". Chávez explained how he had "read the classics of socialism and of military theory and study the possible role of the army in a democratic popular revolt". The way Chávez designed the electoral system and the fast rate of elections assisted him since his opposition did not have the same amount of resources and funding that he had. During election campaigns, Chávez was portrayed in many ways; such as being an athlete. An advertisement promoting housing built by the government told the story of a man who received housing and made the statement: "First God, then my commander" (referring to Chávez with the latter). His "election propaganda" also involved murals, effigies and art representing Chávez's eyes. According to William J. Dobson, author of "The Dictator's Learning Curve: Inside the Global Battle for Democracy", "Chávez didn’t fear elections; he embraced them" because "[r]ather than stuffing ballot boxes, Chávez understood that he could tilt the playing field enough to make it nearly impossible to defeat him".
