LEARNING EFFECTIVENESS: THE USE OF TEACHING AT THE RIGHT LEVEL (TARL) APPROACH IN GEOMETRIC TRANSFORMATION MATERIAL

Abstract

The existence of differences in students' learning abilities or readiness to understand certain material, especially in mathematics subjects, causes gaps in understanding between students in one class. One alternative solution that can optimize teaching flexibility with different student abilities is to use the Teaching at the Right Level (TaRL) approach. TaRL is a learning approach that refers to the level of student achievement or ability. Therefore, this research aims to determine the effectiveness of the TaRL approach on the learning outcomes of class XI MAN 1 Lamongan students on geometric transformation material. This type of research is quantitative research with a quasi experimental design. The sample in this study was class XI MIPA 4 with 35 students as the experimental class and class XI MIPA 5 with 35 students as the control class. The research instruments used were pretest and posttest sheets in essay form. Meanwhile, the data collection technique in this research uses tests. The data analysis technique in this research is descriptive and inferential analysis. The research results show that the Teaching at the Right Level (TaRL) approach is effective in improving the learning outcomes of class XI students at MAN 1 Lamongan. This can be seen from the results of the hypothesis test which has Asymp. Sig. (2 − tailed) of 0.000 < 0.05.
