Abstract

AbstractThe facts show that students' understanding of the concept of absolute value is still in low classified. The lack of understanding of student concepts is influenced by several factors, one of which is lack of student confidence in working on problems. self confidence is one part of student learning independence. Therefore this study aims to describe the understanding of the concept of the absolute value equation in terms of student learning independence. The research method used is descriptive qualitative in the form of case studies. Subjects were thirty-eight students in SMA Negeri 2 Pontianak. The results of this study indicate that students' understanding of concepts is balanced with learning independence. students who have a high level of learning independence overall the results of the concept understanding test are also high. students who have a level of independence of learning while overall the results of the test understanding of the concept are also being. students who have low levels of learning independence overall the results of the concept understanding test are also low. The conclusion from study's result showed that level the high student's independence learning, the level student's concept understanding was high also.Keywords: Absolute Value Equations, Concept Understanding, Learning                  Independence

Abstract

AbstractThe purpose of this research is to elaborate and describe the student error in provingmathematical statements using mathematical induction and their cause. The method ofthis research is descriptive with case study. The research subject are the student of classXI MIA SMA Islam BAWARI Pontianak. Data collection tools used diagnostic tests andinterviews. Based on the data analysis, the errors under taken by student consisted ofthree types of errors, namely conceptual errors, procedural errors and technical errors.Of the three types of errors, the most common is procedural errors. The causea ofstudent errors are that students are fixated on the sample questions given, students don’tunderstand the principle of mathematical induction, the nature of multiplication ofexponents, as well as meaning and use of the assumption n = k is true. In addition,student also don’t understand what statements are proving in the induction step, theprocedure for proving the n=k+1 and manipulate algebraic expressions in the inductionstep. There is no explanation during the online learning process so that students cannotsolve problems. Students are in a hurry when writing answer from the scribble sheet tothe answer sheet.Keywords: Error, Mathematical Induction, Proving
