Abstract

This study investigates the ability of prospective chemistry teachers to identify learning theories embedded in instructional videos. A descriptive qualitative case study was conducted involving 48 students enrolled in the Foundations of Science Education course at Universitas Negeri Makassar. Three chemistry instructional videos were deliberately designed to incorporate elements of behaviorist, cognitivist, constructivist, humanistic, and cybernetic theories. Students analyzed the videos using an identification sheet to document their observations. The findings reveal varying levels of recognition across the learning theories. Constructivist theory was most frequently identified in Video 1, while behaviorist principles dominated Videos 2 and 3, particularly in segments emphasizing drill, repetition, and stimulus–response reinforcement. Cognitivist theory appeared consistently, though less prominently, across all videos. In contrast, humanistic and cybernetic perspectives were recognized to a lesser extent, suggesting that affective, motivational, and systemic components were less explicitly represented. These results underscore the importance of integrating diverse learning theories in video-based instruction to promote not only conceptual understanding but also motivation, empathy, and systemic thinking. The novelty of this research lies in positioning instructional videos as pedagogical representations that reveal prospective teachers’ reasoning about learning theories, rather than merely treating them as delivery tools. This approach provides a new lens for evaluating theoretical literacy in teacher education and emphasizes the need for reflective engagement with instructional media during teacher preparation.

Abstract

This research aims to identify and analyze the contribution of ethnochemistry in supporting the development of 21st-century skills within the context of chemistry education. This study is important because many studies identify ethnochemistry as a highly potential field, but few have thoroughly examined how ethnochemistry can be applied to support the development of 21st-century skills. Using a Systematic Literature Review (SLR) approach, this research collects and evaluates relevant literature on the relationship between ethnochemistry and 21st-century skills. Thirteen articles were selected from a pool of 79 collected articles. Several 21st-century skills supported by the articles include scientific literacy, chemical literacy, critical thinking skills, and problem-solving abilities. The analysis shows that the dominant 21st-century skills supported are scientific literacy (46%) and chemical literacy (38%). These percentages are obtained by comparing the number of articles for each skill with the total number of articles analyzed. The conclusion of this study is that the 21st-century skills supported by ethnochemistry include scientific literacy, chemical literacy, critical thinking skills, and problem-solving abilities. However, there are still limitations: firstly, most studies are local and contextual; secondly, most studies use short-term designs, without long-term follow-up; thirdly, research instruments in several studies are limited to questionnaires and student perceptions, without data triangulation. This study recommends further research into the integration of ethnochemistry to support 21st-century skills such as critical thinking, problem-solving, creativity, collaboration, and others. Moreover, it is necessary to integrate ethnochemistry into the chemistry education curriculum, incorporating ethnochemistry as part of the teaching method that can enrich the teaching material with local cultural contexts.

Abstract

Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycemia and remains one of the major contributors to global morbidity and mortality. The development of safer and more effective antidiabetic agents from natural products has gained increasing attention due to the limitations of current synthetic drugs. Morinda citrifolia root has been reported to contain various anthraquinone derivatives with potential bioactivity. This study aimed to evaluate the inhibitory potential of 23 anthraquinone derivatives from Morinda citrifolia root against the α-glucosidase enzyme using an in silico molecular docking approach. Molecular docking was conducted using AutoDock Vina against α-glucosidase (PDB ID: 5ZCC) after protein preparation in UCSF Chimera. The docking targeted the catalytic site containing key residues (Arg411, Gln256, and Asp327) that interact with acarbose, and interaction patterns were analyzed using BIOVIA Discovery Studio Visualizer. The results demonstrated that several compounds exhibited stronger binding affinities than the standard inhibitor acarbose (-8.4 kcal/mol), while maintaining similar interaction patterns. In particular, compound 21 (-8.9 kcal/mol, H-bond with Gln256), compound 18 (-8.7 kcal/mol, H-bond with Arg411 and Gln256), and compound 15 (-8.3 kcal/mol, H-bond with Gln256 and Asp327) emerged as the most promising candidates. These findings suggest that anthraquinone derivatives from Morinda citrifolia root may serve as potential α-glucosidase inhibitors and warrant further pharmacokinetic and experimental validation.

Abstract

The limited availability of learning media capable of facilitating students’ understanding of abstract concepts in chemical bonding prompted this research. This study aims to determine the validity level of the developed interactive multimedia and to assess teachers’ and students’ responses toward its use. The research employed a Research and Development (R&D) method using a modified ADDIE model, limited to the development stage. The trial subjects consisted of two chemistry teachers and 9 students for the small-scale test, as well as 30 students from grade XI at SMAN 2 Sekadau for the large-scale test.The validation results from experts indicated that the interactive multimedia was highly valid with an average percentage of 94.17%, consisting of 88.33% for the media aspect, 96.25% for the material and language aspects, and 97.92% for the assessment aspect. Student responses reached an average of 90.69% in the small-scale test and 94.53% in the large-scale test, while teacher responses reached 83.07%.The novelty of this research lies in the use of interactive multimedia equipped with a variety of engaging features, such as ice-breaking activities and educational games, which are rarely implemented in chemical bonding learning at the senior high school level. Therefore, the developed interactive multimedia can be used as a learning medium and further tested for its effectiveness.

Meanwhile, the Quiz Team strategy aims to improve group cooperation through fun activities. This study aims to determine the effect of applying the Talking Chips model based on the Quiz Team strategy on students' interest and learning outcomes. The research was conducted with a quantitative approach using a quasi-experimental method and a post-test only control group design. The study was conducted at SMPN 26 Pontianak City in the even semester of the 2024/2025 academic year with a sample of two eighth grade classes with equal academic abilities. The experimental class received learning using the Talking Chips model based on the Quiz Team strategy, while the control class used conventional learning. The research instruments consisted of a learning interest questionnaire and a post-test learning outcome test.The results showed that the average learning outcome score of students in the experimental class (68.23) was higher than that of the control class (60.16), with a significant difference based on the Mann-Whitney test (Sig. 0.046). The Effect Size value of learning outcomes was 0.52, indicating that the learning model had a moderate effect on learning outcomes. In addition, in terms of learning interest, the experimental class obtained a “Very High” category with an average of 91.8%, while the control class was in the “Fair” category with an average of 69.4%. The t-test showed a significant difference (Sig. 0.000) with an Effect Size value of 2.02, which means that the learning model has a very large effect on learning interest. This study combines the Talking Chips model with the Quiz Team strategy as a cooperative learning approach that has been proven effective in increasing student interest and learning outcomes simultaneously.

Abstract

Diabetes mellitus remains a significant global health problem, requiring safer and more effective therapeutic agents. Peroxisome Proliferator-Activated Receptor gamma (PPAR-γ) plays a crucial role in regulating glucose metabolism by enhancing insulin sensitivity, making it a key target in the development of antidiabetic drugs. Pioglitazone, a PPAR-γ agonist from the thiazolidinedione class, has long been used as a conventional therapy; however, its long-term use is associated with side effects such as fluid retention, weight gain, and an increased risk of heart failure. The World Health Organization recommends the development of natural-based drugs with minimal adverse effects. One promising plant candidate is Mikania cordata, which has been reported to possess antidiabetic activity and contains various bioactive compounds, including terpenoids, flavonoids, sterols, and sesquiterpenoids. This study aimed to evaluate the bioactive compounds of Mikania cordata as potential natural PPAR-γ agonists using a molecular docking approach. A total of 36 ligands from M. cordata were docked to the PPAR-γ protein (PDB ID: 2PRG), with Pioglitazone serving as the positive control. Docking was performed using PyRx with the AutoDock Vina system after ligand and protein preparation with UCSF Chimera 1.16. The docking results were analyzed using BIOVIA Discovery Studio Visualizer to identify the interactions between the ligand–protein complexes. The results showed that Cordatolide exhibited the lowest binding affinity (–9.1 kcal/mol), followed by Stigmasterol (–8.9 kcal/mol), both of which were better than Pioglitazone (–8.8 kcal/mol). Interaction analysis revealed that Cordatolide formed two hydrogen bonds with key residues ARG288 and GLY284, accompanied by stable hydrophobic interactions without any unfavorable contacts. Meanwhile, Stigmasterol also showed competitive affinity, although its stability relied solely on hydrophobic interactions without hydrogen bonding. Therefore, Cordatolide demonstrates strong potential as a natural PPAR-γ agonist with fewer side effects compared to conventional therapies. This study provides a novel finding on the potential of M. cordata as a natural PPAR-γ agonist; however, further in vitro and in vivo evaluations are required to confirm its pharmacological activity.
