Abstract

Motivation for healthy living is an effort to achieve optimal physical and mental health levels. One of the factors of healthy living behavior is the existence of healthy living motivation in a person. Students who have been equipped or have healthy living motivation will consistently carry out a healthy lifestyle. This condition is because the student is already motivated to maintain their health. However, if the student is not motivated to implement a healthy lifestyle, it will not be easy to maintain a healthy lifestyle consistently. The research method used in this study was an online search or literature study, which obtained information and data by analyzing valid research articles from both national and international sources. The study results showed that five articles examined the influence of motivation and healthy living behavior. Thus, motivation and healthy living behavior have a significant influence. As explained, the tendency to act is based on the motive to achieve a high degree of healthy living, and that person must have high motivation. The results of this study are expected to provide insight for other researchers to conduct similar research.

Abstract

Improving student learning outcomes and motivation is a central focus in developing effective instructional models. This study compares the effects of the Think Talk Write (TTW) and Expository models on science learning outcomes, viewed from students' learning motivation levels. The research aims to: (1) determine the effect of learning motivation on science learning outcomes; (2) determine the effect of learning models (TTW and Expository) on science learning outcomes; and (3) examine the interaction between learning motivation and instructional models on students' science learning outcomes. Using a quantitative experimental design involving 64 students in Simalungun Regency, data were collected through tests and questionnaires and analyzed using Two-Way ANOVA. The analysis revealed that learning motivation significantly influenced outcomes (F = 3.188; p = 0.049; η² = 0.099), the learning model had a stronger effect (F = 11.587; p = 0.001; η² = 0.167), and there was a significant interaction between the model and motivation (F = 3.707; p = 0.031; η² = 0.113). The model accounted for 41.8% of the variance in learning outcomes (R² = 0.418). These findings highlight that aligning teaching models with students’ motivation levels especially through TTW enhances the effectiveness of science learning through active engagement and deeper conceptual understanding.

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

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.
