Abstract

Abstract. This study aims to analyze the learning obstacles and mistakes of Indonesia high school on the problem of the geometric sequence. The research used descriptive qualitative. Data of the research was obtained from the results of tests and interviews were given to fifty students from one of the senior high schools in West Java. The test is given consists of four questions related to the problem of the geometric sequence. The answer to the questions was confirmed again by a clinical interview. These data are analyzed based on the framework of learning obstacles to the students answer. The results showed that there are still many students who experience learning obstacles in geometric sequences. Learning obstacles that occur include ontogenic obstacles, epistemological obstacles, and didactical obstacles. Based on the obstacles learning that found in the geometric sequence, the authors present several alternatives which are thought to minimize students learning obstacles.
