Abstract

This study is development research, which aims at developing chemistry learning tools based on discovery learning with a contextual approach to the buffer solution which is valid, practical and effective. The development model employed in this study referred to 4D development model, which consisted of define, design, develop, and disseminate. The learning tools developed are RPP, LKPD, Student teaching materials, Media, and THB. The results of the study reveal that the learning tools based on discovery learning developed which had been validated indicates that the mean score is 3.58 which is in very valid criteria. The learning tools based on discovery learning is stated as practical and effective, because the results of the practically test reveal (1) the implementation of learning tools based on discovery learning is in the average of M = 1.74 in the category of (1.5 ≤ M ≤ 2.0) meaning that the aspects and criteria observed on the implementation of learning tools based on discovery learning is in entirely implemented category, (2) the teacher gave a very positive response on the learning tools based on discovery learning with the percentage of 91.61%, and (3) the students gave a very positive response on the learning tools based on discovery learning with the percentage of 87.36%. The learning tools is also met the criteria of effective with the following results that the learning outcomes has met effective criteria where the average score of 78.10 is obtained with the classical completeness 85.19. Therefore, the results of the study shows that the product of learning tools developed is categorized as valid, practical, and effective.

Abstract

The purpose of this study was to determine the improvement of students' problem-solving skills through the application of the discovery learning model and evaluate the effect of the application of the discovery learning model on improving students' problem-solving skills in stoichiometry material in class X.2 SMAN 5 Mataram. The research method used is Classroom Action Research (PTK) which generally consists of three cycles. Each cycle has four stages, namely planning, action, observation, and reflection. This research was conducted in class X-2 SMAN 5 Mataram which amounted to 35 students. This study focused on stoichiometry material which includes the concept of moles in relation to concentration; limiting reactions; and molecules and empirical formulas. The data collection techniques used were formative tests, observation sheets, and documentation. From the research results obtained 88.57% of students have reached completeness in achieving indicators on problem solving skills in cycle III. So, using the discovery learning model is effective enough to improve students' problem-solving skills.
