The Effect of Argument-Driven Inquiry (ADI) on Argumentation Skills and Students' Concept Mastering of Human Excretory System Materials
Get PDFThis study aims to determine the effect of the Argument-Driven Inquiry (ADI) learning model on students' argumentation skills and mastery of concepts in human excretory system material, especially in the sub-material of kidney disorders. The research method used quasi-experimental with a group pretest-posttest design. The sample of this research was second-grade MIPA students in one of the high schools in Bandung, which consisted of 29 students in the experimental class and 25 students in the control class. The purposive sampling technique did the sampling. The study used some instruments, which consisted of a test of argumentation skills in the form of essay questions, an exam of mastery of concepts in the form of multiple choice, and a questionnaire on student responses to learning using the ADI learning model. The results showed that the ADI learning model had a more significant effect on argumentation skills in the experimental class than in the control class, with a significance value of 0.019. The quality of students' argumentation was at level 3. However, the ADI learning model did not significantly affect students' mastery of concepts in the excretory system material because a significant difference was not found between the pretest and posttest data in both research classes. Student response data shows students respond completely well to applying the ADI learning model. Therefore, the ADI learning model is recommended for biology teachers to improve students' argumentation skills and concepts mastery in other biological materials
The Impact of Engineering Design-Based STEM Education on Students' Attitudes Toward STEM and Problem-Solving Skills
Get PDFThe impact of engineering design-based STEM education on 9th-grade high school students' attitudes toward STEM and their problem-solving skills was examined in this study. The subject of factors affecting the heat conduction rate in solids was taught using STEM education. In an experimental design with one group pre-test and post-test, students completed a STEM attitude scale and problem-solving inventory before and after the treatment. According to the paired samples t-test findings, students' attitudes toward mathematics, engineering, and 21st-century skills increased significantly, whereas their attitudes toward science and problem-solving did not change. The eta-squared effect size suggests a high level of change for other dependent variables but only a moderate change for problem-solving skills. In light of the findings, several recommendations about incorporating engineering design-based STEM education have been suggested
A Research on Teachers’ Views about the Metaverse Platform and Its Usage in Education
Get PDFThis study was conducted to determine primary and secondary teachers' views of the concept of "metaverse". In line with the aim of the study, a questionnaire consisting of closed and open-ended questions about the metaverse platform and its applications in the field of education was applied to 122 teachers. The results showed that approximately 65% of the teachers stated that they knew the concept of the metaverse and its applications. In addition, approximately 55% of the teachers stated that they first heard about the metaverse concept from social media, and 45% stated that they were most aware of metaverse applications in the field of play. Most teachers (69.7%) answered no about the benefits of the metaverse platform in education. Approximately 95% of the teachers stated that they wanted seminars and workshops on metaverse applications in education and wanted these studies to be mostly aimed at introducing the metaverse platform and its applications in the educational environment. Based on the study results, introductory pre-service and in-service studies can be conducted for teachers regarding the metaverse and its applications in the field of education and its possible benefits
Students Engagement in Science during Covid-19 Pandemic: Role of Self-Efficacy Beliefs and Achievement Goals
Get PDFThis study investigated the relationships among achievement goals, self-efficacy beliefs, and engagement in science during COVID-19. Distance education was launched due to COVID-19, and there is a need to examine these relations in the online science learning context. Participants were 448 students between 5th and 8th graders receiving distance education for eight months. Path analysis indicated mastery-approach goals and particular self-efficacy aspects positively predicted student engagement. Science communication and conceptual understanding have become prominent among self-efficacy aspects, while higher-order cognitive skills were unrelated to student engagement. Also, negative linkages were identified between performance-approach goals, emotional engagement, cognitive engagement, and performance-avoidance goals. The variance explained in the engagement components ranged from 47% to 60%. Some of the participants’ engagement and motivation in science were negatively affected by distance education. Suggestions were made to foster students’ engagement and motivation in distance science education
Implementation of Research-Based Learning for Prospective Physics Teachers: A Case Study
Get PDFProspective physics teachers must have research skills because they will later utilize and transfer these skills throughout their teaching careers. However, research shows that students' research skills, including in Indonesia, are still low. In addition to equipping students with theoretical research knowledge, an emphasis is needed on the practical stage for prospective teachers in obtaining research skills. Using a reflective case study approach with qualitative methods, this research observes and describes the implementation of research-based learning for prospective physics teachers. The research-based learning was implemented through an experiment on resistance utilizing alternative tools and materials. Data was collected through participant observation from four participants, with the researcher as the main instrument. This study shows that the implementation of research-based learning provides an opportunity for prospective physics teachers to practice research skills and apply the scientific method to solve problems. More studies are needed regarding implementing research-based learning, especially in higher education
Unearthing the Academic Time Capsule: Delving into the Evolution of Science Education Among Indonesian Students
Get PDFThe Indonesian education system, in general, still has many challenges in learning science. The results of the 2018 PISA survey put Indonesia in 74th place, which is sixth from the bottom. Indonesian students' reading ability, with a score of 371, is in the 74th position; Mathematics, with 379, is in the 73rd position; and Science, with a score of 396, is in the 71st position. This situation is intriguing to explore how history influences the education system's current conditions, especially in science learning. The article will explore the effect of changes in the education system on science learning in Indonesia. Exploration of science learning will start from the education system before the independence of Indonesia to the current education system. Using a historical approach, and this article concludes that political power influences change in the ideological orientation of the system and the direction of education, especially in education policy, curriculum changes, and learning activities. This change in situation plays a huge role in determining the achievements of current science learning and achievements
The Impact of STEM-based laboratory activities on pre-service science teachers’ competence perceptions in 21st-Century Skills and STEM Awareness
Get PDFThis study aims to investigate the impact of laboratory activities prepared based on STEM-based learning on the competence perceptions in 21st-century skills (learning and innovation skills, life and career, information, media, and technology skills) and STEM awareness. The sample group consisted of 53 pre-service science teachers studying in year 2 of a public university. A quasi-experimental design formed the basis of this experimental study conducted as a quantitative research model. Pre-service teachers were randomly assigned, one to the experimental group (n=28) and the other to the control group (n=25). The experimental group was presented with laboratory activities based on STEM-based learning. In contrast, the control group had only laboratory activities (i.e., a group of students who did not conduct STEM-based laboratory activities). The measurement tools were the 21st Century Skills Competence Perception Scale (21st Century SCS) and the STEM Awareness Scale (SAS). All participants in the study expressed their agreement generally on the level of “I agree” for all three dimensions of the 21st Century SCS regarding STEM. As a result of the implementation, the SCS sub-dimension of “information, media and technology skills” and SAS skills of the experimental group students were higher than those of the students in the control group. It was found that the experimental group used the media and technology effectively and to use technology to access, analyze and share information. It was also thought that the individuals' problem-solving, critical, and high-level thinking skills developed more than the control group, thanks to the higher STEM awareness in the experimental group. Finally, some implications were proposed based on the research results from the STEM-based learning laboratory activities
Effects of Soil Textures, Soil Settlements, and Soil Water-Holding Capacity on Landslides: An Experimental Study for Science Teachers
Get PDFExperimentation is a contributing factor to the interest and meaningful learning of Science. In Geology and Earth Science, the effects of soil textures, settlements, and water-holding capacity are parameters for landslides in Barotac Viejo and other flooded areas. Landslides are triggered during heavy rainstorms, causing severe property damage and casualties. This experimental study aims to determine how these parameters are factors for landslides and give accurate information to Science teachers. The study uses two methods to provide ease and continuity of measurements and settings using the Fourier Transform Infrared(FTIR) spectroscopy in analyzing the soil textures. The Imhoff cone instrument is for the settling and water-holding capacity of the soil. FTIR Soil analysis reveals that contents of clay and organic matter directly affect soil water-holding ability due to the larger surface area. A landslide-prone zone has a lesser settling time except for the sand that settles fastest due to larger masses. This study is crucial for science teachers teaching geology and earth sciences besides forecasting and preventing geohydrological processes and developing better landslide warning strategies to mitigate risks and reduce socioeconomic damage
A Meta-Analysis of the Effectiveness of Digital Technology-Assisted STEM Education
Get PDFThe purpose of this study was to reveal the effect of digital technology-assisted STEM (Science, technology, engineering, and mathematics) education on academic achievement. To achieve this purpose, experimental studies, including pre-test and post-test, were examined by meta-analysis. The study's data were obtained from 34 studies that met the inclusion criteria due to the searches made in the Databases of the National Thesis Center of the Council of Higher Education, where Turkey's postgraduate theses are located. Effect sizes of 38 comparisons were calculated from these studies. The study calculated effect sizes based on Cohen’s d coefficient. The effect size obtained after the analysis was found to be d=2.582. This finding shows that STEM education assisted by digital technology greatly affects academic achievement. In addition, a significant difference was found between the effect sizes in the study according to the level of education and the subject discipline of academic achievement. This research is expected to contribute to educational practice and future research
Visual Content Analysis of STEM-Related Content in Indonesian Vocational High Schools Biology Textbooks
Get PDFThis research aims to analyze the characteristics of STEM-related visual content in Indonesian Vocational High School biology textbooks. Biology textbooks have been adapted to the latest scientific and technological advances and curriculum demands and declared feasible. However, some distributed biology textbooks in Indonesia may need to be improved and have various areas for improvement and problems. This study used NVivo to perform a descriptive statistic comprising 197 visual samples from the two biology textbooks. The results have shown that the type of "sketch comics" is the most common at 30.5%. In addition, the type of "representation" is the most visual function found in this study, with 44.7%. The study has seen all of the STEM domains appearing in biology textbooks. Most of the STEM domain with visual content relates to scientific content. Other components discussed in detail and essential to the development of the student learning unit are schematic views displaying biological processes and representation functions. Therefore, the authors of biology textbooks need to consider the types and functions of visual content holistically, particularly regarding the context of the topics that can represent effective visual content and develop student understandin
