Abstract

This study aims to develop a learning tools GOAL model (Graphic Organizer-Based Argumentation Learning). The set of GOAL model is expected to be a chemistry learning tool that can improve students' argumentation skills. This study uses a Research and Development methodology with a 4-D design consisting of Define, Design, Develop and Disseminate. The results showed that: 1) the developed GOAL model tools consisting of lesson plans, LKPD, teaching materials, and assessment instruments with good validity. 2) GOAL model tools are easy to use by teachers and students during the learning process in class, and 3) GOAL model learning tools have high effectiveness in improving students' argumentation skills. These results indicate that the GOAL model can be applied in chemistry learning to improve students' argumentation skills.

Abstract

This research aims to identify the potential of medicinal plants in Pampang Village, Samarinda, East Kalimantan, which can be used as a source of chemistry learning at the junior and senior high school levels. This research used a descriptive method with a qualitative approach. Data collection was carried out through observation, interviews, and documentation. The research subjects, namely 11 residents of Pampang Village, were determined using purposive sampling. Data analysis used interactive model analysis, and data validity is measured using data triangulation techniques. The results of the research show that there are 20 medicinal plants that the people of Pampang Village widely used and eight medicinal plants have the potential to be used as a source of chemistry learning. These medicinal plants were sambung nyawa, meniran, bajakah, betel, seri, turmeric, coconut, and tamarind eggplant. These plants related to materials separating mixtures, reaction rates, functional groups, lipids, acid and base indicators, electrolyte and non-electrolyte solutions, acids and bases, chemical changes, and redox. Therefore, this can be used as a reference and consideration for chemistry teachers in the learning process. to help students understand chemistry lessons closely related to everyday life.

Abstract

This research aims to develop chemical learning tools in the form of RPP, LKPD, Handout, and assessment instruments that are valid, practical, and effective. This research uses research and development design (Research and Development, R &D). The model used in this study is a modification of the 4-D model from four stages to three stages 3-D including the define, design, and development stages proposed by Thiagarajan. RPP, LKPD, handouts, and assessment instrument validation sheets are used to measure the validity of learning devices. Student response questionnaires and observation sheets for the implementation of learning activities are used to measure the practicality of learning devices. Pretest-posttest, N-gain, and effect size tests are used to measure the effectiveness of learning devices. The results showed that learning devices were declared very valid with a percentage of 90%, learning devices were declared practical with a percentage of 83%, effective learning devices to improve learners' learning outcomes based on the results of N-gain calculations by 0.6 meaning that the increase in learners' learning outcomes belonged to moderate categories and effect size calculation results of 2.01 belonged to the category of very effectiveness levels tall.
