Abstract

The purpose of this research are to know (1) the influence using REACT learning strategy about increase student’s mathematical inductive reasoning skills, and (2) the influence using REACT learning strategy about increase student’s studying motivation. Population of this research was the students grade VIII of SMP. The sample was 34 students as the experimental class that given treatment REACT learning  and 31student as the control class with expository learning. Data collection in this study by using test and questionnaire techniques. Data were analyzed by using t test. The result of the research showed that 1) the value of sig 0,03 <0,05 meaning that there is influence of applying of REACT learning to improvement of mathematical inductive reasoning ability of student of class VIII SMP, (2) sig value 0,041 <0,05 meaning that there is influence of application of REACT learning to increase motivation learn math class VIII SMP.

Abstract

The purpose of this study was to design and determine the validity of the Tri N-based Mathematics E-LKPD to improve the critical thinking skills of junior high school students on the subject of algebraic forms. This type of research is research and development which refers to the 4D development procedure which consists of 4 stages, namely define, design, develop, and disseminate. However, this research was only conducted up to the develop stage. The result of this research is that a product has been developed in the form of Tri N-based Mathematics E-LKPD to improve the critical thinking skills of junior high school students on the subject matter of algebraic forms and the validity of the E-LKPD based on the validation results of 9 validators, the calculation of V Aiken with a range of V Aiken is at 0.728 to 1 fall into the high validity category.

Abstract

This study aims to (1) design an electronic mathematical student worksheet based on Tri N on the subject of integers and fractions; (2) knowing the level of validity of the electronic mathematics student worksheets based on the Tri N. The stages of this research use Define, Design, and Develop, which are part of the 4D stage of RND. The data collection technique used at the define stage is documentation and journal analysis, while at the develop stage is a validation sheet filled out by validators (math teachers and mathematics education lecturers). The data analysis technique carried out at the define and design stages is descriptive qualitative, while at the develop stage is a quantitative descriptive analysis using Aiken validity. The results showed that the design process obtained a mathematics learning tool in the form of Mathematics E-LKPD which was suitable for use. This can be seen from the results of the V-Aiken calculation obtained in the range of 0.691 to 0.988.
