Abstract

This paper discusses the application of project-based learning (PBL) to improve student’ psychomotor skills and concept understanding, as well as knowing what PBL contribution to the improvement of student’ psychomotor skills in chemistry learning. The study was conducted in three cycles. Each cycle consisted of planning, implementation, observation, and reflection steps. One set of data consists of student’ psychomotor skills assesment, student’ conceptual understanding and questionnaire responses were obtained from the action research. Learning process was performed in the eleventh grade students included 37 students (10 males and 27 females) and 3 collaborators. The successful research was indicated by 85% of students achieve the mastery learning on concept understanding and well on psychomotor aspects. Data collection was performed using documentation method by questionnaire, observations, and tests. Data was analyzed quantitatively and qualitatively. The results show that all aspects of the psychomotor assessed include sets, mechanical response, complex response, adaptation, and origination were in high category. At the end of the lesson, the project assigned to students were evaluated jointly between teachers and students. The project results in the form of a series of distillation apparatus is applied to separate the natural compounds.

Abstract

Student’s critical thinking and their learning result depend on learning design and student’s activity.  Most students use their spare time with playing game.  Students are more challenged by the difficulty in playing game rather than facing the difficulty in understanding the lesson.  This phenomenon is the basic reason of the researchers to develop a game that has the essence of the subject matter, namely Chemistry Board Game (CBG) or we can call it with Al Chemist Knight.  This research aims to develop a suitable digital game based on android system. In this research media was used to improve the cognitive learning and critical thinking. It also has purpose to evaluate the response of learners in learning chemistry through alkane derived compound topic. The development of this game was adapted from the procedure of game development process in mobile 3D presentation.  The collection of evaluation data model applied was pre test and post test in trial class.  The result showed that in the pretest the learning result average was 34.35 with classical target of 5%.  While the posttest learning result average was 80.51 with  classical target of 85%. The  n-gain factor was 0.703.  Based on the result of the students questionnaire data analysis, 3.025 of students responded positively to the implementation of CBG.  A CBG media makes an assessment of critical thinking, in which the indicator of critical thinking which are focusing on questions get 3,1 point, giving arguments get 2.95, asking and answering questions get 3.0, making decision get 3.05, and the average score of critical thinking indicator is 3.025 which belongs to good category. Based on the students’ response questionnaire, we get the average score of 3.3 or 82.5% which is classified in good category.

Abstract

This study aimed to determine the pattern of a more effective learning approach between the inductive and deductive approach in improving students’ conceptual understanding referring to the international standard curriculum on the X graders for the material property particulate subject matter. Through the deductive approach, students already have a picture/concept in their minds. But by using an inductive approach, students use their logic to understand concepts and summarize it. The research method applied in this study is a descriptive-comparative method with a triangulation analysis technique. Instruments used in the study were a questionnaire for the students, observation sheets, and three-tier diagnostic test items for pretest and posttest. The average pretest scores for deductive and inductive classes were 54.70 and 48.25, respectively. The result of the observation sheet analysis showed the deductive approach surpassed 12 points more than the inductive approach in improving the student’s learning activity. The result of the questionnaire analysis showed that 38 of 68 students prefer the learning process using deductive to inductive approach, and thought that it was suitable with the students’ characteristics. While the average posttest scores for deductive and inductive classes were 68.16 and 55.47, respectively. The analysis result of the N-Gain test towards the pretest and posttest results regarding the three-tier diagnostic test items indicated achievement of student’s conceptual understanding using a deductive approach which was 14.2225% higher than the use of the inductive approach. The Triangulation Analysis stated that the deductive approach was more effective in improving students’ conceptual understanding of Chemistry and material topics as well as material classification. While the inductive approach was more effectively applied to the topic of Particle Kinetic theory.
