The Learning Tools development of Rectangular and Square Material Oriented toward the Learning Cooperative Setting and included Bruner Theory on Students

Abstract

The purpose of this study is to produce valid, practical, and effective mathematics learning tools on rectangular and square material which oriented toward cooperative setting learning and included Bruner’s theory in VII grade students of State MTs of Bontotangnga, Bulukumba Regency, South Sulawesi. This type of research was a research and development that produced learning tools consisting of Lesson Plan (RPP), Handout (BS), and Student Worksheet (LKS). The subject in this research was 25 students of VII grade of State MTs of Bontotangnga Bulukumba regency, South Sulawesi in the academic year 2018/2019. The mathematics learning tools development, which used, refered to the Thiagarajan 4-D model. The learning development approach system carried out includes 4 stages such as, define, design, develop, and disseminate. The data collection instruments were the learning device’s validation sheets that aimed to obtain the experts and practioners validation data regarding the Lesson Plan (RPP), Handout (BS), and Student Worksheets (LKS). The student activity observation sheet aimed to obtain student activities data during the learning process by using cooperative setting learning tools which included Bruner’s theory that have been developed. Meanwhile, the learning outcomes tests aimed to measure the cognitive aspects of students in the form of a description test. The data analysis technique used was validity, practicality and effectiveness data analysis. The results showed that: (1) Lesson Plan (RPP) and Student Worksheet (LKS) were categorized as very valid. Meanwhile, the Handout (BS) were categorized valid, (2) Practical, based on the observations, the learning device was well-implemented in the trial process, and (3) effective. Hence, this has fulfilled the three criteria such as, the effective student activity, the responses toward the positive learning, and mastery learning classically achieved.
