Abstract

Algebra is a branch of mathematics that is abstract in form so that students do errors in solving problems of Algebra. The purpose of this research is to describe: (1) the errors form made by students in solving algebraic operation story problems based on the Newman stage, (2) the scaffolding form given to students who make errors in solving problems of algebraic form operations. This research is a qualitative descriptive with research subjects of 3 students of class VIII at MTs Unggulan Singa Putih. The results of the study state that: (1) the errors form on the reading step is students cannot read the problems by beheading or stopping correctly, on the comprehension step the students do not know the meaning of the problem, on the transformation step the students cannot modelling variables appropriately, on the process skill step the students unable to perform operation of algebraic forms appropriately, on the encoding step the students cannot answer correct conclusions, (2) the scaffolding forms given to students is students are requested to recheck or reread the results of their work, students are given questions that lead students to think more about the problem, and give praise to motivate students to improve their work.

Abstract

Problems that occur in mathematics learning are essential to pay attention to. Problems in mathematics learning are problems that must be resolved with the right solution. This research aims to conduct a literature review on mathematics learning problems in schools. The method used in the study is a literature review. The sample used is the research results related to mathematics learning problems at the elementary, junior high, high, and college levels from student and teacher factors. Data was collected by collecting all published articles from the latest year according to educational level. Then, analysis and conclusions are drawn based on the data obtained. The research results show that the problems found at each station are different. So, the solution used must be the problems faced.

Abstract

The abstract nature of mathematical objects makes learning mathematics difficult and many students experience difficulties in learning mathematics. The purpose of this study was to determine the effect of the Geo - Gebra- assisted STAD learning model on the ability of students' mathematical understanding of learning styles. This study uses a quasi-experimental research method. The population of this study were students of SMA in the 2015/2016 academic year. The research sample was taken by cluster random sampling. The sample size is 64 students, consisting of 34 students in the experimental class and 30 students in the control class. As a research instrument , the researcher conducted a mathematics learning achievement test and a learning style questionnaire. Data were analyzed using two-way ANOVA. The conclusions of this study are: Geogebra- assisted STAD -type collaborative learning model Winplot produces better mathematical comprehension abilities and mathematics learning achievement compared to PowerPoint-assisted direct learning models. Students with a visual learning style are at the same level as students with an auditory learning style. Students with an auditory learning style are at the same level as students with a kinesthetic learning style. Students with a visual learning style perform better in school than students with a kinesthetic learning style.
