This study provides essential information about the creativity of chemistry education students in facing the digital era, as well as challenges and opportunities that must be considered in the development of chemical education innovations in the digital era.

Improving student chemistry laboratory performance through Nyamplung ethnoscience-oriented learning of the Sasak tribe

2024-10-16T08:28:12-03:00

Evaluating student performance in open-ended laboratory settings presents challenges compared to the structured format of typical lab exercises, which often resemble recipes. This study aims to enhance student performance by integrating local ethnoscience into chemistry education, using the Nyamplung tree (Calophyllum inophyllum L.), part of the Sasak tribe’s knowledge, as teaching material. The study employed a pre-experimental pretest-posttest design with 17 chemistry students participating in three lab sessions. All course participants were selected as research subjects using purposive sampling. Performance was assessed through portfolios, and the N-gain method was used to analyze improvement. Results showed consistent performance increases, with scores rising from 75.52 to 87.76 over three sessions and N-gain values indicating positive but low-category improvement (0.015, 0.070, 0.181). These findings suggest that integrating ethnoscience-based materials can improve student performance while offering a culturally relevant learning experience.

Scientific creativity of secondary school students on colloid system

2024-07-27T11:00:17-03:00

The significance of scientific creativity in science has been highlighted for nearly two decades. In chemistry education, this involves students’ ability to generate concepts related to chemical problems and phenomena, such as the colloid system found in daily life. Understanding the colloid system requires students to produce scientific ideas for problem-solving. Therefore, assessing students’ scientific creativity is crucial. This research aimed to determine students’ scientific creativity concerning the colloid system using a descriptive, quantitative approach. Seventy-six students were selected through simple random sampling. Data collection involved four open-ended questions, analyzed using a scoring rubric and percentage scores. The study revealed that students’ fluency, flexibility, and originality were low, leading to unsatisfactory results in questions requiring divergent thinking and scientific imagination. These findings highlight the need to enhance students’ ability to generate scientific ideas, emphasizing the importance of fostering scientific creativity in education.

Determining design thinking elements in chemistry education: A Fuzzy Delphi method

2024-09-07T19:59:17-03:00

Creating a high-quality learning environment where students can solve real-world problems and be receptive is essential for fostering students’ innovation competencies. Using appropriate pedagogical strategies and classroom activities is a crucial aspect of Malaysian education. This article uses the Fuzzy Delphi Method (FDM) to design chemistry classroom teaching strategies based on the design thinking paradigm. This research involves 12 experts in purposive sampling to form a diverse panel encompassing expertise in Chemistry Education, Curriculum, Module Development, Research, and Innovation. Using the Fuzzy Delphi method (FDM), the data were analyzed. Four elements for exploratory constructs, two elements for construct interpretation, four elements for ideation, two elements for execution, and three elements for construct evolution met the FDM requirements, according to the findings. Its threshold value is less than 0.2, the expert consensus is less than 75%, and the average score of the fuzzy number is over 0.5. Encouraging design thinking in chemistry classes and thereby enhancing students’ innovation skills, this research unquestionably induces a paradigm shift in teaching practice.

The effectiveness of guided inquiry learning based on Anderson’s sketch analysis on students’ higher order thinking skills in reaction rate

2024-10-09T18:45:33-03:00

The 21^st century learning process focuses on enhancing higher-order thinking skills (HOTs). In Indonesian schools, students’ HOTs in the reaction rate topic need improvement. This study investigates the effectiveness of guided inquiry learning based on Anderson’s learning sketch analysis in enhancing HOTs. Involving 60 of 11^th grade science students from a public high school in Malang, the study used a quasi-experimental design with an experimental class (Anderson’s learning sketch) and a control class (conventional learning). The research instrument was a HOTs assessment with 10 essay questions. Data analysis using an independent sample t-test showed a significant difference (p = 0.002), with the experimental class scoring higher (69.3) than the control class (49.9). The findings indicate that Anderson’s Learning Sketch Analysis is effective in improving students’ HOTs, with the experimental class outperforming the control class in skills such as analysis (63% vs. 39%), evaluation (71% vs. 55%), and creation (78% vs. 70%). These results highlight the importance of guided inquiry in enhancing HOTs.

Critical thinking skills of prospective chemistry teachers in chemistry learning with Ethno-Socio-Scientific issues integrated inquiry

2024-08-22T18:02:07-03:00

This study aims to develop a valid and practical Ethno-SSI integrated inquiry strategy to improve the critical thinking skills of prospective chemistry teachers. The research method used is Plomp’s research and development model, with a convenience sampling technique obtained from a sample of 52 prospective chemistry education teachers at one of the universities in Indonesia. Data was collected through observation, a critical thinking test, and a questionnaire. Data analysis was carried out qualitatively and quantitatively. The results of strategy development obtained a new syntax called OETACA (orientation, exploration, transformation, argumentation, conclusion, and application) with a content validity score of 0.83 and construct 0.93. The results of improving critical thinking skills on a small scale get an N-Gain score of 0.7 in the high category supported by the perceptions of prospective chemistry teachers who strongly agree (43%) and agree (41%) to implement the Ethno-SSI integrated inquiry strategy in chemistry learning in the classroom.

Enhancing student motivation in reaction rate topics through the integration of Instagram-based learning media and the Student Teams-Achievement Divisions cooperative model

2024-10-23T10:51:39-03:00

Instagram-based learning media can be applied in chemistry learning because it can be accessed at any time, it is not limited by distance or time if you have an internet network and adequate hardware and can increase student learning motivation. This study aimed to ascertain whether applying the Instagram-integrated Student Team-Achievement Divisions learning model and multi-representation strategies enhances student motivation on reaction rate topics. The Nonequivalent Control Group Design with the Quasi-Experimental technique is the research design. Using a random sampling technique, students from Malang Senior High School’s class XI-Science were selected as the research sample. Student learning motivation data was descriptively and quantitatively examined, and statistical tests, such as prerequisite analysis tests and hypothesis testing, were used to analyze data on learning outcomes. The results of this experimental research found that in the extremely high category, the percentage of students who were motivated to learn rose from 56 to 85%. These findings show the experimental class’s improvement in learning motivation outperformed that of the control class.
