Abstract

Chemistry learning in vocational schools is often limited to general concepts and lacks connection with students vocational expertise, making it difficult for them to apply theory to practice in agricultural product processing. This study aims to develop acidbase teaching materials using the four-step teaching material development (4STMD) method for students in the agricultural product processing agribusiness program at vocational high schools. The research responds to the lack of curriculum-aligned and contextually relevant resources that integrate chemistry with vocational practices. The study employed development research (DR), focusing on the first two stages of the 4STMD method: selection and structuring. In the selection stage, materials were designed based on basic competencies 3.5 and 4.5, producing eight learning indicators and sixteen concept labels. Acidbase concepts were compiled from national and international textbooks and contextualized with agricultural applications, such as pH control in fermentation. In the structuring stage, concept maps, macro structures, and three levels of representation (macroscopic, microscopic, and symbolic) were developed to link chemical theory with agricultural practices. The draft materials were refined through expert review to ensure clarity and scientific accuracy. The results indicate that the developed teaching materials are systematic, scientifically valid, and relevant to the curriculum. They also integrate substantive and pedagogical contexts that support students vocational learning needs. This study shows that the 4STMD method is effective for producing chemistry teaching materials that are structured, contextual, and applicable, thereby enhancing the relevance and quality of chemistry education in vocational high schools

Abstract

Students need computational thinking skills to help them face global challenges with rapid technological development. For this reason, teachers must be able to implement CT in learning by paying attention to students' interest in learning, one of which is using educational games. Designing CT-integrated educational games requires appropriate strategies such as mastery learning. This study aims to analyse the development of educational game design using mastery learning strategies so that it can provide an overview to educators in developing the media to improve students' CT skills. This research uses a qualitative descriptive method. The data obtained was analysed bibliometrically using the VOS Viewer application. The VOS Viewer analysis shows that there is a connection between game design, computational thinking, and mastery learning that began in 2016. The results also show that there are 4 things that become the basis for designing educational games, namely cognitive, motivational, affective, and sociocultural perspectives

Abstract

This study aims to develop a contextual colloidal system module with a batik wastewater treatment context that is suitable for senior high school students. The development of this module is motivated by the widespread use of teaching materials that do not fully align with curriculum demands, focusing solely on scientific content without applying a contextual approach. The research method employed is Design Development Evaluation (DDE), while the development of the teaching material follows the Four Steps Teaching Material Development (4STMD) model. In the design stage, analysis and planning of the type of teaching material to be developed were conducted, resulting in an initial draft of the module. The development stage, based on 4STMD, consists of four steps: selection, structuring, characterization, and didactic reduction, leading to the creation of a draft teaching material. The evaluation stage involved feasibility testing by chemistry teachers and experts, and comprehensibility testing with students. The evaluation results indicate that the developed contextual teaching material, based on the batik wastewater treatment context, is aligned with the curriculum, conceptually accurate, and feasible for use as independent learning material. The feasibility test yielded a percentage score of 95.4%, and the comprehensibility test yielded a score of 92%.

Abstract

A flipbook with augmented reality based on ethnoscience, supported by Heyzine and Assembler, contains nanotechnology content for high school students. It is an interactive learning media in the form of an electronic book that contains photos, text, and animated content designed to assist students in learning the material through the visuals offered. Page flipping has a transition effect that helps students read each page and increases their learning use. Applied visual arts ethnoscience exemplifies the combination of community culture and science. Augmented reality is utilized to show objects in 3D and realistically related to the ethnoscience of applied fine arts in the Cirebon area, such as the scissor-grip home, megamendung batik, ceramics, masks, kujang, and paintings. The goal of this research is to develop digital teaching materials that can adjust to evolving technologies in order to increase educational quality. The data was collected using a quasi-experimental one-group pretest-posttest design for a total of 30 students, which was then processed using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation) using descriptive statistics. This study found that students had good perceptions of the presence of a flipbook media with AR based on ethnoscience. Ethnoscience-based digital learning media can be used as interactive learning media because they provide precise visualizations of the concepts and conditions encountered during the learning process.

Abstract

The merging of adaptive chemistry subjects (C.1) into the IPAS project subject in the Independent Curriculum causes the chemistry content to be non-specific and not adapted to all vocational elements. This has the potential to hinder students' understanding of relevant chemistry concepts in their vocational context. This study aims to design an outline of chemistry teaching materials that are relevant to the needs of dyeing subjects in Textile Finishing Engineering VHS. The method used is Qualitative Content Analysis (QCA) with four stages to obtain and evaluate chemistry content related to the dyeing context. The results show that there are 19 chemistry contents that have been systematically arranged and validated based on the sequence, details, and their relationship to the dyeing context. For example, the content of electrolyte solution, acid base, ion equilibrium in solution, and reaction rate plays an important role in regulating the affinity of dyes to fibers and the speed of the dyeing process. This outline is useful for teachers or education practitioners as a clear guide to integrating chemistry content and vocational contexts into learning or teaching materials. For students, it can help them understand chemistry concepts that are more contextual and applicable to their vocational fields.

Abstract

Microbial literacy plays an essential role in understanding microbiology issues. Discussion of socioscientific issues is one way to improve microbial literacy and argumentative skills. Socioscientific issues discussion takes a long time if applied in an inadequate classroom. Thus, social media is used as a tool to discuss socioscientific issues. This study aims to utilize social media Facebook' in discussing socioscientific issues. The research method used is quasi-experimental. The pre-post one group design was used to know the effect of socioscientific discussion on argumentation skills, and the pre and post-control group design was used to know the differences in microbiological literacy of students who discuss socioscientific issues and did not discuss socioscientific issues. Discussion of socioscientific issues is carried out through four steps: polemic, exploration, conclusion, and action. The results showed increased individual argumentation skills before and after discussing socioscientific issues via Facebook. Before the discussion there are 34.38% of students reached argumentation levels 4 to 5, after which 56.25% reached argumentation levels 4-5. Discussion of socioscientific issues through social media has made group argumentation skills reach higher performance (level 5). Microbiological literacy between groups discussing socioscientific issues and not discussing socioscientific issues showed no significant difference except for questions directly related to the topic of discussion, namely changes in perceptions of microbes. Online discussions of socioscientific issues with pro and con arguments were very effective through social media "Facebook."

Abstract

The abstract nature of chemistry often leads to low student comprehension, a problem exacerbated by a lack of teaching materials that connect concepts to real-world situations. This research aimed to develop a valid, practical, and effective contextual teaching module on the colloid system using Four Steps Teaching Material Development (4STMD) method. The research following the stages of Design, Development, and Evaluation (DDE). The module's unique context is the application of colloid chemistry principles to the treatment of tofu liquid wastewater using Moringa oleifera seeds as a natural coagulant. The development process followed the four stages of 4STMD: Selection, Structuring, Characterization, and Didactic Reduction. The module's quality was evaluated by three expert chemistry teachers and tested for understandability with 63 high school students. The results of the expert validation indicated that the module is Very Feasible, with high scores in content (95.2%), language (85.7%), presentation (93.7%), and graphical feasibility (85.3%). Furthermore, the student understandability test yielded an average score of 93.33%, categorizing the module as "High" and suitable for independent learning. It is concluded that the 4STMD method successfully produced a viable and effective contextual module that bridges the gap between abstract chemical concepts and their practical, sustainable applications.
