Abstract

This research was aimed to 1) develop a Science Learning LKPD based on Discovery Learning on subject materials Work and Simple Machine in Daily Life for VIII Middle School Students; 2) find out the feasibility of Discovery Learning based LKPD on subject materials Work and Simple Machine in daily life for VIII grade junior high school students; and 3) knowing students responses to the development of Discovery Learning-based LKPD on subject materials Work and Simple Machine in daily life for VIII grade junior high school students. This research includes development research (design research) with a 4-D development model. Data collection techniques used assessment instruments by material experts, media experts, peer reviewers, science teachers, and grade VIII students in junior high schools. The data analysis technique uses the quality analysis of LKPD. Based on the assessment of expert lecturers, peer reviewers, and science teachers, the average score of 4.31 was obtained with a percentage of 86.43% stating that the quality of the LKPD was very good (VG). The results of students' responses obtained an average score of 4.31 with a percentage score of 86.43% stating that the quality of the LKPD IPA Very Good (VG). It can be concluded that the developed Natural Sciences LKPD is suitable for use in learning science in schools.

Abstract

This study aims for knowing process developing students worksheet based on value clarification which is decent used to improve character of Junior High School grade VIII students. The study type was research and development (R&D) of 4D (Define, Design, Develop dan Disseminate) model which is restricted untill develop stage. The techniques of collecting data used observatins, questionnaires, and interviews. Quality value data obtained then analyzed used qualitative and quantitative descriptive analysis based on ideal assesment.

Abstract

Science learning is related to life and phenomena that occur in the surrounding environment. The learning process will be more meaningful if science is associated with the culture that develops around the community environment and can also be called using an ethnoscience approach. However, science learning in general still does not integrate the culture of both the school environment and the environment of the students. This culture can be learned by learners starting from daily activities such as in the process of making food products, one of which is in the fermentation process in the manufacture of tempeh. This study aims to identify ethnoscience in the fermentation process that can be implemented in learning. Research method used in the form of literature review method. Data collection is done by observation, interview, and analysis of articles or journals. Data analysis techniques are carried out by analyzing the results of observations, interviews, and scientific articles. The results of this literature study prove that ethnoscience-based science learning is important to be implemented in order to foster the critical thinking skills of learners.
