Abstract

This activity aimed to enhance partners’ expertise in developing AI-based STEM-PBL learning materials, thereby advancing education, science, technology, and human resource development. It also provided training, technology application, and support to improve the quality of education through innovative learning media. Key issues identified included teachers’ low motivation to create technology-based resources, students’ lack of enthusiasm, limited technology use in chemistry classes, and teachers’ insufficient skills in utilizing digital tools. To address these challenges, strategies such as socialization, training, technology deployment, mentorship, and evaluation were implemented. These efforts focused on encouraging teachers and students to engage in problem-solving and innovative learning practices. The program’s effectiveness was reflected in the improvement of participants’ understanding, shown by an increase in the mean pretest score (51.43) to the posttest score (79.13). Thus, the objectives of enhancing mastery of the material and applying knowledge in practice were successfully achieved.

Abstract

The methyl eugenol formic ester is the intermediate formation of the 1-(3,4-dimethoxy phenyl)-2-amino-2-cyano propane compound, a hypertension drug. This study aimed to find the value of the reaction order and study the mechanism of an addition reaction of methyl eugenol with formic acid to produce the methyl eugenol formic ester. Gas chromatography analysis of the residual methyl eugenol determines the reaction order. There are two dominant products in the synthesis of methyl eugenol formic ester, resulting in the formation reaction of methyl eugenol formic predictable in a two-way reaction mechanism. The determination of the energy of the reactants, products, and transition compounds in the formation reaction of methyl eugenol formic ester compound prescribed through computational studies using NWChem 6.0 and visualization using Jmol. The results of the analysis of the data obtained several conclusions: The value of the reaction ordered for methyl eugenol with formic acid is the first order. Based on the computational result shows that the enthalpy change for the reaction product is ΔH(1) = -47,810 KJ/mol and ΔH(2) = -60,545 KJ/mol. The activation energy for both transition compounds is Ea(1) = 163,1937 KJ/mol and Ea(2) = 370,3477 KJ/mol. This fact indicates that the formation of methyl eugenol formic ester compound using the method (1) was more likely than (2). The prediction is based on the determination of Ea with the computational chemistry following the experimental result, which shows the product of (1) more than the product of (2).

Abstract

High Order Thinking Skills (HOTS) is a thinking process at a higher cognitive level, including the ability to solve problems, think creatively, think critically, argue and make decisions. This ability is expected to be possessed by students in the era of modernization and globalization of the 21st century. This achievement can occur if learning and assessment have implemented HOTS. However, in practice, many teachers still do not use HOTS questions to evaluate students in schools because of their low understanding of how to analyze and create HOTS questions according to Bloom's Taxonomy. This PkM activity aims to: 1) help partner groups increase insight and understanding regarding HOTS and its implementation in learning; 2) Helping partner groups improve skills in creating HOTS questions; and 3) meet the partners' needs for creating HOTS-based questions according to Bloom & Anderson-Krathwohl's Taxonomy independently. The methods used in this PKM are socialization of PKM activities, program preparation, implementation, mentoring and program monitoring and evaluation. The results that have been achieved are increasing partners' understanding of HOTS by 37.75%. This PKM activity can increase the knowledge and skills of madrasa stakeholders, especially teachers and staff. With independence in creating questions, teachers will better understand how questions can be connected to objectives and indicators, and in accordance with Bloom & Anderson-Krathwohl's Taxonomy and can improve teachers' ability to create questions independently, which will ultimately improve their skills in answering and analyze the questions.

Abstract

Developing Higher Order Thinking Skills (HOTS) remains a major obstacle in the global drive for STEM education in the twenty-first century, especially in complex subjects like stoichiometry. Although Inquiry-Based Learning with STEM (IBL-STEM) fosters critical thinking and Canva is frequently used for educational design, no previous study has combined these strategies to solve the conceptual challenges of stoichiometry. This study aimed to create and verify a Canva-based stoichiometry teaching resource and examine its effectiveness in improving chemistry students' HOTS. We created interactive Canva modules with guided inquiry tasks, molecular visualization, and HOTS assessment using the ADDIE paradigm (Analysis, Design, Development, Implementation, Evaluation). The materials were tested with 62 students using pre-test/post-test comparisons and validated by three chemistry education specialists (mean feasibility scores: 4.71 for content and 4.74 for media). With post-test scores (76.94 ± 6.61) significantly surpassing pre-test findings (35.71 ± 6.36), the intervention significantly improved HOTS (mean gain: 41.23 ± 9.33, p < 0.001). The results of this study indicate that the Canva-IBL-STEM model is valid for implementation in stoichiometry learning and has been shown to improve students' HOTS abilities. The findings provide educators with a model for inquiry-driven, technology-enhanced learning that connects design tools with profound conceptual knowledge.
