Development of Chemical Learning Module Based Learning Cycle 5E to Improve Students Learning Outcomes in Equilibrium Chemical Content in Class XI MAN 2 Ground Flat

Abstract

ABSTRACT This research starts from the problem of the low critical thinking skills of students in Chemistry learning. Chemistry learning is one of the lessons that are difficult, for students to understand. This is due to the fact that many chemical materials are abstract and the lack of student references to Strengthen the theory of chemistry being studied. Chemical materials is a difficult, material equilibrium. The main difficulty is experienced by students when solving problems related to dissociation equilibrium. Therefore, it is Necessary to develop a learning module that is Appropriate to the characteristics of students. The purpose of this research is to describe the development of a chemical learning module for chemical equilibrium based on the Learning Cycle 5E that is valid, practical, and effective for students of class XI MA. The research subjects were students of class XI MIA 1 in MAN 2 Tanah Datar, amounting to 34 students. This type of research is research development (R & D) with a models of development by Plomp, the which consists of four phases of development items, namely the phase of the initial investigation (preliminary investigation), the phase of design, the phase of realization / construction, and the testing, evaluation, and revision phases (test, evaluation, and revision). This study uses a quantitative approach. This type of research the data in the form of quantitative Data consists of three types of the data items, namely the Data Validation results by experts, assessment data results by practitioners, and effectiveness of data in the form of activity of data and student learning outcomes. The results Showed that the chemistry learning modules based on Learning Cycle 5E for Class XI MA students developed was valid, practical, and effective. This can be seen in the module validity of 81.11 with valid criteria. The module practicality by the teacher is 98.18 with very practical criteria and the module practicality by students is 74.80 with practical criteria. The effectiveness of the module, the which consists of student activities has a value of 92.16 with very active criteria and student learning outcomes have a classical average of 85.88.
