Abstract

Molecular geometry is one of the biggest challenges in science education. Since molecular structures exist at a microscopic level, students often struggle to visualize them in three dimensions (3D), making it difficult to understand concepts such as bond angles, molecular shapes, and electron pair interactions. This study explores the role of spatial ability in high school students’ understanding of molecular geometry. Using a quantitative descriptive method, the study examined the spatial ability and molecular science comprehension of 58 high school students. Data were collected using standardized tests, including the Mental Rotation Test (MRT), shape assembly, and 3D visualization for spatial ability, along with a molecular science comprehension test focusing on VSEPR theory. The results obtain that students' spatial ability is significantly low, with average scores falling far below expected standard. The results suggest the need for more effective teaching strategies that incorporate 3D visualization tools to enhance students’ ability. Future research should focus on interactive learning approaches, such as virtual simulations to help students better visualize molecular structures and improve their understanding of science concepts.

Abstract

Tailoring Micro, Small and Medium Enterprises (MSMEs) or often called Tailors experienced an extraordinary economic downturn during the Covid-19 pandemic. Convection innovation as a form of existence in the midst of a pandemic outbreak that still exists today to survive must carry out various kinds of creativity. One of them is digitizing the marketing system, updating fashion trends, increasing relationships, providing the best service, collaborating with agencies, and others. In this service the focus is on digitizing the system and developing the concept of relations using the graph theory concept to increase competitiveness. The location of the service will be focused on one of the tailors, namely Sarinah Tailor in Kedunghalang Village, North Bogor District.

Abstract

Learning media is created to enable interpersonal interaction between teachers and students and provide a significant learning situation for students. The problem that arises in MGMP Science Sukabumi Regency is that teachers still find it difficult to make learning videos, need learning applications that are easily accessible, need innovative and creative learning media, so this service activity is carried out with the aim of developing and implementing learning media systematically based on the needs and characteristics of students. This media is also aimed at changing behavior according to the goals to be achieved which is carried out by three methods, namely preparation, implementation, and evaluation. This activity resulted in an understanding of teacher competence in dealing with generation Z and an understanding of materials practices for making interesting and interactive learning media based on previously prepared teaching materials This solution was chosen because it was in accordance with the ability and experience of the implementer, which has produced interesting and interactive learning media for students so that it has a good impact on partners. An analysis of the condition of the Sukabumi Regency MGMP IPA shows that PKM partners have done many things to improve the competence of science teachers in their area.

Abstract

Science learning in several schools in the Serang district still rarely conducts practicum, although practicum kits are available. Therefore, it is necessary to train teachers who are members of the Science MGMP Serang District. The purpose of the activity is to improve the skills of teachers to design simple practicums and use practicum kits. Activities were carried out in the duration of 34 JP in the form of training and assignment activities. Training session 1 was conducted online with output in the form of practicum designs made by teachers, while session 2 training was carried out offline at SMP Negeri 1 Ciruas. Academic evaluation is carried out on the collected tasks and non-academic evaluation includes participants' responses to training activities. The data obtained were analyzed in a quantitative descriptive manner. The results of the activity showed that teachers had varied teaching experiences, and the number of assignments collected was 40 practicum designs. Teachers are skilled in drafting practicum designs and using kits well. Teachers are satisfied with the training activities and hope that the activities can be carried out sustainably. After the activity, teachers are expected to be able to apply the knowledge and skills they have gained to carry out practicum activities in learning science at their respective schools

Abstract

The industrial revolution in the 21st century demands the creation of a generation that is responsive to change and has the competencies of Critical Thinking, Creative Thinking, Communication, and Collaboration (4C). The contextual learning process based on ethnochemistry is expected to increase students' motivation and interest in learning chemistry. Chemistry subjects that are classified as difficult and can be linked to local culture are the colligative properties of solutions. This study aims to analyze chemical literacy through learning with an Ethnochemical approach to the material of colligative properties of solutions. The research method used is quantitative descriptive research. Data collection using a test method, the test method is in the form of multiple-choice chemical literacy questions with a total of 10 validated questions and has a reliability index in the moderate category. The test method aims to determine students' chemical literacy in terms of content, context, and competence. The results of the study showed that the average chemical literacy of students in terms of content aspects was 49.2%; context aspects of 40.4%, and competency aspects of 50.6%. Th e average chemical literacy from these three aspects is categorized as “Not Enough”. The results of the study concluded that chemical literacy in ethnochemistry-based learning is in the “Not Enaough” category. The recommendation from this study is the need for innovation in chemistry learning through integration between ethnochemistry and STEM as well as the development of teaching materials in the form of ethnochemistry-based books that support the learning process.

Abstract

This study aims to analyze the effectiveness of the STEM-based Project-Based Learning (PjBL) model in improving students' scientific creativity on the topic "Separation of Mixtures" in class VIII of SMP Negeri 36 Jakarta. The background of this study departs from the need for science learning that is able to foster creativity and critical thinking through contextual and collaborative experiences. The method used is a quasi-experimental with a pretest-posttest non-equivalent control group design, involving two classes of 36 students each. The experimental class used the STEM-based PjBL model, while the control class applied the Discovery Learning model. Data were collected through creative thinking skills tests and analyzed with SPSS. The results showed a significant increase in students' creativity scores in the experimental class (p = 0.000) with a large to very large effect size based on Cohen's d calculation and Hedges' correction. These findings indicate that STEM-based PjBL has a strong practical effect in developing students' scientific creativity. In conclusion, the implementation of STEM-based PjBL is effective in improving creative thinking skills through contextual, collaborative, and challenging learning, and contributes to strengthening the science education approach that is oriented towards developing 21st-century competencies.

Abstract

This project aims to develop and test Ethno-STEM-based e-books to enhance students’ chemical literacy and sustainability awareness regarding the colligative properties of solutions. The e-book’s development integrates coordination science with local knowledge, enabling students to understand chemical concepts in a relevant and applicable manner. The research strategy employed is RD using the ADDIE model. The e-book was approved by media and content specialists and tested on students to assess its effectiveness in improving chemical education and sustainability awareness. The level of feasibility based on media expert judgment is 89% in the "Valid" category, and media experts are 95% in the "Valid" category. Also, the CVR value is 0.86 and the CVI is 0.93, both of which are in the valid range. E-Books improve students' chemical literacy and sustainability awareness, with N-Gain indices of 0.745 in the "high" category and 0.541 in the "moderate" category—long-term impacts and applications to other disciplines are to be studied to support ESD programs.
