Validity and Practicality of The Salt Hydrolysis Electronic Module Based on Structured Inquiry with Interconnection of Three Levels of Chemicals Representation

Abstract

Salt hydrolysis is one of the chemical’s material with the associated aqueous reaction in solution. The material is difficult to understand for students. Based on interviews, the learning process has not been interconnected by three levels of chemicals representation. The purpose of the research to decide on the validity and practicality of the salt hydrolysis electronic module based on structured inquiry with the interconnection of three levels of chemicals representation. The method of research was used by Researched and Development of Plomp model. The research instruments are used by sheets validation and sheets practicality. The electronic module was validated by 4 experts. The practicality of the electronic module was checked by 2 chemistry teachers and 60 students at two High Schools in Padang City. Validity and Practicality were analyzed by utilizing Cohen’s Kappa Statistic. The outcomes of validation showed that the electronic module had an almost perfect strength of agreement with a Kappa was 0.87. The practicality level had substantial strength of agreement with a Kappa was 0.80 for the student’s reaction and also almost perfect strength of agreement with a Kappa was 0.85 for the teacher’s reaction. Therefore, the result electronic module of salt hydrolysis can be used as a good alternative for teaching-learning chemistry in high school.

Validity and Practicality of E-Module Model Inquiry Based Online Learning to Improve Student Competence

“…The trial phase of the developed product was carried out at SMA N 1 Koto Baru Dharmasraya semester 1 of the 2022/2023 school year. These results are in accordance with the research results (Rachmawati et al, 2021) that a research product will be said to be valid if the product is useful for the curriculum. This is proven by the utilization of e-module products in class XI at SMAN 1 Koto Baru Dharmasraya.…”

Three Levels of Chemical Representation-Integrated and Structured Inquiry-Based Reaction Rate Module: ItsEffect onStudents Mental Models

“…Structured inquiry-based modules have been proven practical for learning in senior high school students (Adriani et al,2021;Nurhasanah, 2020;Rachmawati et al, 2021). The result of this research together with the literature review suggest teachers to use modules or other similar types of learning materials that are designed accordingly to the structured inquiry model and completed with chemical multiple representations.…”

“…One of the abstract chemical materials is salt hydrolysis material. Abstract chemical concepts will be easier to understand by involving three levels of chemical representations, namely macroscopic, submicroscopic and symbolic representations (Sagita et al, 2018), (Yani et al, 2019), (Rachmawati et al, 2021), (Utari & Azra, 2022), (Adawiyah & Azra, 2022). Learning by applying chemical multirepresentations provides facilities for meaningful or in-depth learning to occur (Sagita et al, 2017), and is able to improve understanding of chemical concepts and chemical problem solving (Sari & Helsy, 2018).…”
