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

The purpose of this study was to obtain a chemical practicum KIT as an effective learning medium to train students' science process skills in scientific method, polar and non-polar covalent compounds, electrolyte and non-electrolyte solutions. This study uses a 4-D research model which includes the stages of defining, designing, developing, and distributing. However, in this study only limited to the development stage. The results of the research obtained showed that classical completeness in the posttest workmanship on all three materials was 100%. While the increase in learning outcomes aspects of science process knowledge and skills in the three materials are in the category of "medium" and "high". Based on the results, it can be concluded that the practicum KIT learning media is effective for training science process skills in scientific method, polar and non-polar covalent compounds, electrolyte and non-electrolyte solutions.

Abstract

Many chemistry teachers claimed that identifying students' understanding genuinely is challenging due to the limited time available, and the overload works faced. Therefore, constructing an efficient and valid instrument to overcome this difficulty is a must. This study is a part of the big project to produce a robust four-tier instrument to identify students' conception of acid-base properties of salt solution (FTI-ABPS2). The project involved six groups of researchers, and each group carried out the study in 6 different participant groups and schools. This paper outlines the development and validation of a four-tier instrument of Acid-Base properties of salt Solution involving public secondary school students in Malang Regency. The instrument was constructed using the procedure as carried out by Habiddin & Page (2019). Twenty-eight questions were constructed for the instrument. The results show that the instrument is valid and reliable to be implemented further. In-depth analysis regarding content validity, as well as the empirical validity of the instrument in light with the characteristic of chemical concepts (acid-base properties of salt solution in particular), is also discussed.

Abstract

Abstract. This study aims to evaluate a learning of reaction rates with nested curricular arrangement which is combined with connected curricular arrangement to improve critical thinking skills of the students. The evaluation of this study is based on the result of data collecting toward the implementation of learning, students’ activities, learning outcomes, critical thinking skills, and students’ responses. This study is conducted using scientific inquiry. The research design used in this study is one group pretest-posttest design including pre-experimental research. The subjects of this study are 36 X graders of MIPA 8 at SMAN 1 Manyar Gresik. The result of this study shows that the implementation of a learning of reaction rates with nested curricular arrangement which is combined with connected curricular arrangement to improve critical thinking skills of the students is in very high value category with percentage of agreement around ≥75% and value of the relevant students’ activity is greater than the percentage of the irrelevant students’ activity so that it has a better category. The students’ learning outcomes and critical thinking skills have significantly improved after conducting a learning about reaction rates with nested curricular arrangement which is combined with connected curricular arrangement which is analyzed using t-test. However, there are some students get post-test score under the expected standard value. This learning about reaction rates with nested curricular arrangement which is combined with connected curricular arrangement receives a positive responses from the students of 87, 22% by collecting data using a questionnaire response.Keywords: Critical Thinking Skills, Inquiry, Nested, Connected
