Abstract

This research aimed to test the validity of the feasibility of traditional game learning media on salt hydrolysis. This research was development research (R&D) with a qualitative descriptive approach. This research uses the ADDIE model development design, which consists of 5 (five) stages, namely (1) analysis, (2) design, (3) development, (4) implementation, and (5) evaluation. Data collection techniques in this study used a validation sheet for the assessment of the feasibility of tumbu-tumbu  learning media. The tumbu-tumbu  learning media validation wass assessed by 4 expert validators, namely 2 chemistry lecturers of State University of Gorontalo material experts, 1 media expert lecturer, and 1 high school chemistry teacher. The results of the validation of tumbu-tumbu  learning media development obtained an average percentage 0f 89.40%, which was categorized in very feasible criteria. Therefore, the tumbu-tumbu  learning media are highly usable in the learning process of salt hydrolysis.

Abstract

Abstract. The change in the educational paradigm in the 21st century requires students to have good basic knowledge and understanding to develop Higher Order Thinking Skills (HOTS). Chemical equilibrium is an abstract material and complex, so it requires good thinking skills to understand the concepts. This Study aims to determine the effect of the application of guided inquiry models on HOTS in chemical equilibrium. This research uses Pre-Experimental Design with One Shot Case Study model with 25 students of Billfath University as subjects. The data were collected using the HOTS test instrument in the form of 15 multiple choice questions. Hypothesis testing used the Independent Sample T-test (non-parametric). The results showed (1) the high-level learning outcomes of students with high initial abilities were better than students with low initial abilities, (2) there was a significant effect of applying the model Guided inquiry learning towards student high-level learning outcomes.

Abstract

Abstract. The purpose of this study was to determine the effectiveness of the problem-based learning model based on ethnoscience on students' critical thinking skills on colloidal material. Experiments were conducted on a sample of 36 experimental class students with an ethnoscience-based problem-based learning model and 36 experimental class students with a convention learning model. This research method is a quasi-experimental design with a nonequivalent control group design. The instruments used are essay tests and observation sheets. The results of this study indicate that the average posttest in the experimental class is 76.08, which is higher than the control class, which is 69.33. These results indicate that the use of ethnoscience-based learning problem-based learning models on colloidal material is effective in improving students' critical thinking skills compared to using conventional models.
