The Development of the Instrument Reasoning Mathematics Courses Set and Logic

This research aims to (1) develop an instrument test, (2) describe the procedure for the development of assessment instruments, (3) demonstrate the feasibility of the evaluation instrument. This research was conducted up to a limited trial. This study uses the model Research & Development (R&D) consists of five activities, namely (a) introduction, (b) design a draft instrument, (c) instrument development assessment (d) a limited trial, and (e) the revision of the development product. Before a limited trial is conducted,the test is validated to the expert material and evaluation. This reasoning test consists of 7 question. Validation of the items included of content validation regarding the article, construction, and language aspects and the suitability of the problems in the test with indicators obtained from expert considerations. Based on validation questionnaire data by a team of experts, it is known that the developed test instrument is declared feasible in the realm of material, construction, and language.
