Abstract

This study aims to determine the characteristics, teacher and student responses, and the effectiveness of STEM-PjBL-based LKS on the material of making peuyeum to improve creative thinking skills in the developed biotechnology material. The method used is a mixed method with an embedded experimental model. This study involved 10 biology teachers and 20 students in Lampung Province at the pre-intervention stage and after the intervention involving 32 grade X students of SMA Negeri 3 Bandar Lampung and 2 teachers as research observers and 1 teacher as a teacher. Data collection was carried out through a LKS validation questionnaire on the aspects of material suitability, construction, and readability for experts, a teacher response questionnaire covering material suitability and readability, and a student response questionnaire after implementing learning using STEM-PjBL-based LKS, as well as a set of pretest-posttest instruments for creative thinking skills. The data analysis technique in this study used the paired sample t-test. The average percentage of expert validation results for the material suitability aspect was 89.77%, construction 90.62%, and readability 87.50% so that the STEM-PjBL-based peuyeum making worksheet was declared valid and had a “very high” criterion according to Arikunto's assessment standards with characteristics following the STEM-PjBL syntax and containing local wisdom in the form of peuyeum. The teacher's response to the material suitability aspect was 93.18% and readability 91.66% and the average student response was 84.81% so that the worksheet was suitable for use in biology learning with a "very high" criterion. The results of the paired sample t-test stated that there was a significant difference between the pretest (41.85) and posttest (72.99) scores of students, so that the STEM-PjBL-based peuyeum making worksheet that was developed effectively improved creative thinking skills.

Abstract

This research develops a Flipped Classroom integrated with STEM with the ADDIE model to improve systems thinking skills. The research subjects were 31 students at Al Kautsar Middle School in Bandar Lampung. At the beginning of the research, it was found that 70% of teachers had not used the flipped classroom, 65% had not integrated STEM, 73% had not understood systems thinking skills which was carried out on 30 teachers, and performance analysis was carried out on 60 students, with the results of 72% learning traditionally, 73% had not integrated STEM and the average value of systems thinking skills is 40. Validators stated that the development instrument was valid with values of 92.12 and 92.52% when limited testing was carried out. Assessment of learning implementation was 89% and assessment of student performance was 88%. The program is effective in improving systems thinking skills in terms of an N-Gain of 0.58 and an effect size of 0.22 in the medium category. Effectiveness is supported by practicality 88%, positive teacher response 88%, and positive student response 81% with very high criteria. The research results concluded that the STEM-integrated flipped classroom program was effective and practical in improving systems thinking skills.

Abstract

This study aimed to develop Augmented Reality-assisted instructional materials on the coordination system, to describe their practicality in improving students’ systems thinking skills, and to evaluate the effectiveness of the developed instructional materials. The research employed a Research and Development (R&D) approach based on the 4-D development model, which consists of four stages: define, design, develop, and disseminate. The instruments used included a needs analysis questionnaire, validity questionnaire, practicality questionnaire, learning implementation observation sheet, and a systems thinking skills pretest-posttest. The results showed that the instructional materials were highly valid, with content validity of 89.5%, construct validity of 94.8%, and attractiveness validity of 97.2%. The Augmented Reality-assisted instructional materials were practical for improving systems thinking skills, as indicated by the implementation of learning activities, which reached 92.5%. Product evaluation responses revealed that most students provided highly positive assessments, with a percentage of 97.22%, while teachers’ assessments reached 95.7%. Furthermore, the instructional materials were effective in enhancing systems thinking skills, as demonstrated by a high N-Gain score of 0.79 and a large effect size of 1.95. Based on these findings, the developed Augmented Reality-assisted instructional materials were effective in improving students’ systems thinking skills.

Abstract

This study aims to analyze teachers' needs for the development of photosynthesis learning based on Argument-Driven Inquiry (ADI) integrated with the Science, Technology, Engineering, and Mathematics (STEM) approach as the basis for developing learning tools. The study was conducted at the needs analysis stage within the Design-Based Research (DBR) framework using a mixed methods approach with a sequential explanatory design. Quantitative data were obtained through a survey of 33 high school biology teachers in Lampung Province using a Guttman scale-based questionnaire, while qualitative data were obtained through in-depth interviews with three biology teachers. The results showed that 66.7% of teachers were not familiar with the ADI model and 54.5% had not implemented the STEM approach in learning. 90.9% of teachers had never used STEM-integrated ADI-based student worksheets, and 100% of teachers had never applied it to photosynthesis material. In addition, 75.7% of teachers had not measured critical thinking skills and 87.8% had not systematically measured collaboration skills. Interview results revealed that teachers still experience difficulties in understanding the implementation of ADI, integrating STEM in learning, developing appropriate learning tools, and facing obstacles such as the abstract nature of photosynthesis material, time constraints, and limited laboratory facilities. Based on these findings, it is recommended to develop a photosynthesis student worksheet based on STEM-integrated ADI equipped with critical thinking and collaboration assessment instruments to support more meaningful biology learning and oriented towards 21st-century skills.
