Abstract

The purpose of this study is to determine the effect of the TGT (Teams Games Tournament) learning model on statistics material for class VII junior high school on mathematical problem solving abilities. This research was a quantitative research using Quasi Experimental Design. The sampling technique in this study used purposive sampling. Class VII D, consisted of 24 students as the experimental class and class VII C consisted 24 students as the control class. The instruments used in this research were Pretest-Posttest with 3 questions. The data analysis techniques used in processing the data were analysis prerequisite tests (normality test and homogeneity test), hypothesis testing, and the N-Gain test. Based on the results of calculations that have been carried out, the posttest average value for the experimental class was 92, while the posttest average value for the control class was 85. In addition, based on the data obtained from the results of the hypothesis testing, it results that the  value is 0.000 then Ho  is rejected and Ha is accepted. This is in line with the average N-Gain value in the experimental class resulting in 0.82 high criteria, while the average N-Gain value in the control class produces 0.66 medium criteria. So it can be concluded that there is an influence of the TGT (Teams Games Tournament) learning model on students' mathematical problem solving abilities.

Abstract

Mathematics anxiety is one of the inhibiting factors in learning which can interfere with the performance of cognitive functions such as concentration, remembering, concept formation and problem solving. Therefore, mathematics anxiety needs to be minimized by examining more deeply the levels and factors of mathematics anxiety. The purpose of this research is to explain the level and factors of mathematics anxiety in prospective teacher students at Mathematics Education Department Universitas Islam Lamongan. Instrument used is questionnaire of mathematics anxiety. The number of subject is 24 students. Based on the questionnaire of mathematics anxiety level, it was found there are three levels of anxiety experinced by the students, namely heavy, medium, and low mathematics anxiety. Heavy mathematics anxiety is experienced by 7 students, medium mathematics anxiety is experienced by 10 students, and low mathematics anxiety is experienced by 7. The factors that affect the level of mathematics anxiety are don't believe himself about his abilities, unpleasant experience in the past, unable to understand the mathematics material well, and pressure from parents to become a mathematics teacher. It can be concluded that prospective teacher students in mathematics education department Universitas Islam Lamongan experience the medium to heavy anxiety level.
