Analizing of field independent and dependent students' understanding in solving statistical problems based on ontosemiotic approach

Abstract

The purpose of this study is to analyze prospective teachers in problem solving ability using an onto-semiotic approach. The onto-semiotic approach is a method emphasizing mathematical object meaning based on language, concept, procedure, computation, proposition and argument. This research is an explorative qualitative. The subject of research is a mathematic students of STKIP PGRI Tulungagung who have high mathematical ability. The main instrument of the research is the researcher herself, the auxiliary instrument are math problems solving test and interview guidelines. The collecting data techniques are tests and interviews. Data analysis consist of data reduction, display and conclusion. The data are validated by time triangulation. The result of the research shows that, prospective teacher have good categories in the language and the concept in understand the problem, good categories in language, concept, procedures and argument in devise a plan, good categories in terms of language, procedures, computations and arguments in carry out the plan, and bad categories in the look back. So, the onto-semiotic approach can be implemented on learning to improve prospective teachers' understanding in solving math problems.
