Abstract

This study aims to determine the students' higher order thinking skills on biodiversity material in class X. This research uses a quantitative descriptive approach. The sample of this study was class X students consisting of 104 people determined by cluster random sampling technique. The instrument used was a test question in the form of an essay of 12 items on biodiversity material. The results showed that students' higher order thinking skills on biodiversity material in class X were at very low criteria with the acquisition of an average student score of 44.5%. In each indicator, it was found that the C4 indicator of class X students was very low with a percentage of 44.3%, the C5 indicator was very low with a percentage of 40.0%, and the C6 indicator was very low with a percentage of 46.0%. Thus, it can be concluded that to be able to improve the higher order thinking skills of grade X students, students begin to familiarize themselves with reading various literatures, solve HOTS-based problems, and students must use various learning strategies.

Abstract

Interactive Student Worksheets (LKPD) based on scientific literacy are an effective alternative learning method for training junior high school students critical thinking skills. This research focuses on developing interactive LKPD based on scientific literacy on photosynthesis material. The aims of this research are (1) to analyze the validity and effectiveness of interactive LKPD based on scientific literacy in training students' critical thinking skills, and (2) to analyze the results of students' critical thinking abilities while using interactive LKPD based on scientific literacy. The research method used is development research with the ADDIE model, which consists of analysis, design, development, implementation and evaluation. The subjects of this research were 30 students in class VII-6 of SMP Negeri 3 Lubuk Pakam. Research data was obtained from validation results by validators, data from critical thinking skills based on observations by observers and data from pretest and posttest results. The research results show that (1) the interactive LKPD developed has very high validity, both in terms of media at 95.24% and terms of material at 85.81%. Interactive LKPD is categorized as effective in training critical thinking skills with a percentage of 63%. (2) The pretest and posttest results show a significant difference with an N-gain value of 0.6, indicating a moderate increase, with classical learning completeness reaching 93%. Thus, this scientific literacy-based interactive worksheet on photosynthesis has proven to be valid and effective in training junior high school students critical thinking skills.

Abstract

This research aims to determine the effect of using STEM-based LKPD on improving students' creative thinking abilities on earth and solar system material at SMP Negeri 2 Kutalimbaru. This research is a type of quasi-experimental research that uses a non-equivalent control group design, namely a design that provides a pretest prior to treatment and a posttest subsequent to treatment. The population in this study were all students in class VII of SMP Negeri 2 Kutalimbaru. The sampling technique used in this research was purposive sampling use 60 students as samples. The sample consisted of two classes, namely class VII-1 as the experimental class which was treated using STEM-based LKPD, and class VII-2 as the control class. Data was collected through observation, teacher interviews, and creative thinking ability tests. The research results were then analyzed using normality tests, homogeneity tests, and hypothesis tests assisted by IBM SPSS Statistics 29.0 for windows. The hypothesis result is Sig.0.001 with a significance level (α) = 0.05. It is stated that 0.001 < 0.05, so a decision can be made that Ha is accepted and Ho is rejected. There is an influence of using STEM-based LKPD on increasing students' creative thinking abilities on earth and solar system material. The ability to think creatively and flexibly (Flexibility) experienced the highest increase. This can be stated based on the N-gain results for this indicator of 91.18.

Abstract

Abstract. This study aims to determine the effect of the Liveworksheets-assisted Problem Based Learning model on biology learning activities and outcomes. This study uses a Quasi-Experimental method with a Pretest-Posttest group design. The sample used was class XI-1 as the experimental class and class XI-2 as the control class. Data collection techniques were through tests (pretest and posttest) to measure learning outcomes and observation sheets to measure student learning activities. The results showed that the Liveworksheets-assisted Problem-Based Learning model had an effect on student learning activities and outcomes in the human movement system material in class XI at SMA Negeri 1 Tebing Syahbandar. An increase in student learning activities can be seen in meeting 1 at 62.6%, meeting 2 at 77.27%, and meeting 3 at 81.82% in the very active category. The increase in student learning outcomes can be seen from the average biology learning outcome score of the experimental class, which was 80, higher than that of the control class, which was 68.83. The results of the Independent Sample t Test showed a significance value < a (0.05), namely 0.000 < 0.05, so H0 was rejected and Ha was accepted. This means that there is an effect of the Problem-Based Learning model assisted by Liveworksheets.Keywords: problem based learning model, liveworksheets, learning activities, learning outcomes.

Abstract

Creative thinking ability is one of the essential demands of 21st-century learning, which needs to be supported by science process skills to foster deeper understanding and meaningful learning experiences. However, science learning in schools is still largely dominated by lecture methods with minimal practical activities, resulting in students being less active, untrained in creative thinking, and rarely engaged in scientific processes. This study aims to investigate the effect of the Project-Based Learning (PjBL) model with a STEM (Science, Technology, Engineering, and Mathematics) approach on students’ creative thinking ability and science process skills in the topic of elements, compounds, and mixtures. The research employed a quasi-experimental method with a pretest-posttest control group design for creative thinking ability and a posttest-only control group design for science process skills. The sample consisted of two eighth-grade classes selected through random sampling, with 30 students in each class. One class was assigned as the experimental group, taught using the STEM-based PjBL model, while the other served as the control group using conventional instruction. Research instruments included essay tests and observation sheets. Data analysis using the t-test revealed a significant effect on creative thinking ability (p = 0.001, p < 0.05) and science process skills (p = 0.004, p < 0.05). The novelty of this study lies in the integration between the design of PjBL and the STEM approach, with systematic measurement of two important indicators of 21st-century learning: creative thinking and science process skills, in the context of applied basic chemistry topics. Thus, the findings affirm that integrating PjBL with STEM is effective in fostering 21st-century skills. Based on these results, it is recommended that innovative and contextually relevant projects be designed to support the development of meaningful science learning.
