Abstract

The instrument is one of the tools used to collect a data, whether or not a research instrument needs to be seen the characteristics of the instrument being prepared. So the purpose of this research is to know the characteristics of test instruments Problem-solving mathematics that have been compiled on the material geometry for junior high school class VII. The research method used is the basic research method. Data analysis is done qualitatively and quantitatively. Qualitative analysis is used to see the characteristic of content validity, whereas quantitative analysis is done to see the characteristics of differentiating power and instrument reliability. The results show that all items have good content validity and distinguishing power, with a very high degree of reliability.

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.
