Abstract

The purpose of this study was to describe the learning
obstacle of students in junior VII in algebra. Researchers gave
test questions to students, interviews and analyze documents.
Then the students' answers were analyzed in depth and
disaggregated by didactical obstacle, epistemoligical obstacle
and ontogonical obstacle. The cause of these learning
obstacles can be seen from many things, among others due to
inaccuracy in reading, inaccuracy in thinking, weakness in the
analysis of the problem, and lack of tenacious. Besides the
learning obstacle is thought to arise such as the design of
didactic presented using the "quick way" so as not providing
understanding of the concept for students, design didactic
presented in its final form that gives less opportunity for
students to explore their understanding, contains a "jumping
thinking" large enough so that the less attention to cognitive
processes students will still have many difficulties in adjusting to
the thought of thinking arithmetic algebra (abstract), the
concepts presented are not systematic and do not support a
thorough understanding of the material to be learned.
