This study aims to analyze the influence of flipped classroom-based project assessment on critical thinking skills and physics learning outcomes. This quantitative research has a post-test-only non-equivalent control group design. The population is distributed into two classes. The data are collected using questionnaires and tests and analyzed using descriptive statistics and Manova. The results indicate differences between critical thinking skills and physics learning outcomes between students who learned with project assessments based on the flipped classroom approach and students who learned with conventional assessments simultaneously and partially. The significance value indicates more than 0.05. Thus, it can be concluded that flipped classroom-based project assessment influences critical thinking skills and concept understanding. Flipped classroom-based project assessment is recommended as one innovative assessment based on constructivism to improve concept understanding and critical thinking. Excellent critical thinking skills and concept understanding will help students solve contextual problems.

This research intends to investigate the effect of digital literacy skills and self-regulation on student creativity in online physics learning practices. The approach used in this research is quantitative, with the data collection technique being a survey model. The research design used a quasi-experimental model with a pretest and posttest design. The samples were physics education students of UIN Sulthan Thaha Saifuddin Jambi, with a total sample of 42 students. Data analysis was conducted through several stages, namely: a) the first stage was to analyze category classification, namely classifying student abilities into very good category (A), good category (B), sufficient category (C), and poor category (D), based on the score of the measurement results of the three variables; b) the second stage is to test the correlation between variables. Correlation data analysis was performed with SPSS 25 software. Based on the data and discussions that have been carried out, it can be concluded that there is an influence between digital literacy skills and self-regulation on students' creativity in online physics learning practices. The effect of digital literacy skills on student creativity in carrying out online physics learning practices is 85%, while self-regulation has an effect of 78%. Both variables together affect students' creativity in learning physics online by 74%.

This study intends to describe and investigate the ability profile of Technological Pedagogy Content Knowledge (TPACK) based on scientific literacy for pre-service primary school teachers. The measurement of student TPACK skills is needed to determine the knowledge of technology that will be implemented in the learning process. Students' TPACK knowledge needs to be developed because integration between pedagogical abilities, material content, and technology is needed. This research is quantitative survey research. This study tested a TPACK model, which was described by the relationship between latent variables, namely from seven components, including TK, PK, CK, TPK, TCK, PCK, and TPACK. The data collection technique used a questionnaire instrument with 46 items. The questionnaire instrument was filled out by 206 pre-service primary school teachers who had taken the Science Concept, Science Application, Science Teaching Learning Course, and Field Experience Practice Courses. The results were then calculated and analyzed using a modeling test with a Structural Equation Modeling (SEM) approach. The results showed that PCK variability could be influenced by the CK and PK components of 51.5%. While the variability of TCK can be influenced by the components of CK and TK of 42.7%. The variability of the TPK can be influenced by the PK and TK components of 45.2%. Finally, the magnitude of the effect of PK, CK, TK, PCK, TPK, and TCK components on TPACK is 61.0%. The TPACK profile of pre-service primary school teachers is good with the factors that contribute most to the components that go into PK and CK. As a result, the findings of this study will contribute to the development of a more thorough profile of the TPACK competencies of pre-service primary school teachers, which can enhance their capacity to incorporate technology when they become teachers in the future.

This study aimed to investigate grade-11 students’ conceptual understanding of chemical reaction rate through 5E inquiry approach in which they were asked to explore data for answering the engaged question using the small-scale syringe-vial experiment (SSVE) and elaborate their understanding using the AR interactive Particulate-level Visualization (ARiPV). The two-tier diagnostic conceptual test and semi-structured interview questions served as the data collection instruments. Thirty-three grade-11 students cooperated in the series of four 2-hour 5E learning activities for a total of 8 hours. Dependent samples T-test analysis showed that the mean score of the postconceptual test (mean 29.77, S.D. 6.77, 66.16%) was statistically greater than that of the preconceptual test (mean 11.68, S.D. 10.14, 25.96%) at the significance level of 0.05. Their actual gain was 40.20% and their normalized gain was 0.54, a medium increase. The majority of them moved from the less correct category, Partial Understanding with Specific Misunderstanding (PMU, 43.03%), to the more correct category, Partial Understanding (43.84%). The semi-structured interview showed that the 5E inquiry technique using SSVE in conjunction with ARiPV was entertaining and successful in identifying and enhancing their understanding. This demonstrated that this integrated intervention can encourage students to shift their conceptual understanding of reaction rate to the more advantageous categories.
本研究旨在通过5E探究法调查11年级学生对化学反应速率的概念性理解,该方法要求学生使用小型注射器-小瓶实验(SSVE)探索数据以回答参与问题,并使用AR交互式颗粒水平可视化(ARiPV)阐述他们的理解。两层诊断概念测试和半结构化访谈问题作为数据收集工具。33名11年级学生参与了4个2小时的5E学习活动,共8小时。依赖样本t检验分析显示,概念后测验的平均得分(mean 29.77, S.D. 6.77, 66.16%)显著高于概念前测验(mean 11.68, S.D. 10.14, 25.96%),显著性水平为0.05。实际增益为40.20%,归一化增益为0.54,增幅中等。他们中的大多数人从不太正确的类别“部分理解带有特定误解”(PMU, 43.03%)转向更正确的类别“部分理解”(43.84%)。半结构化访谈表明,使用SSVE与ARiPV相结合的5E询问技术在识别和增强他们的理解方面是有趣和成功的。这表明,这种综合干预可以促使学生将对反应速度的概念性理解向更有利的类别转移。

The quasi-experimental design of the pretest-posttest controlled group was used in this study. Students of the Social Science Education Department, Universitas Islam Negeri Maulana Malik Ibrahim Malang, Indonesia, were selected as research subjects using a purposive sampling technique. The research subjects were determined to consist of class D as the experimental class (29 students) and class B as the control class (29 students). Questionnaires with a Likert scale of 1 (strongly disagree) – 4 (strongly agree) were used in taking student environmental sensitivity data on environmental issues and conservation materials, totaling 28 items with indicators: knowledge, attitudes, and skills. Subsequently, the data were tested for normality and homogeneity and analyzed using an independent sample t-test. The results showed that the PBHL model had a significant effect on the environmental sensitivity of Social Science Education students on environmental issues and conservation materials ((p (0.009) α (0.05)). The average results of the sensitivity of the experimental class environment (N-Gain = 13.29) were higher than the control class (N-Gain = 8.75). This goal can be achieved through the syntax in the PBHL model. The suggestion for further research is that it is necessary to develop further by combining the PBHL model and interactive mobile learning media as a means for students to investigate and actualize problem-solving.
学生需要具备对环境的敏感性,以便在注意到问题并找到正确的解决方案时表现得积极。本研究旨在探讨phbhl模式是否会影响社会科学教育学生对环境问题和保育材料的环境敏感性。本研究采用前测后测对照组的准实验设计。采用有目的的抽样方法,选取印尼伊斯兰大学内盖里毛拉马利克易卜拉欣玛朗分校社会科学教育系的学生作为研究对象。研究对象确定为D班为实验班(29人),B班为对照组(29人)。问卷调查采用李克特量表1(强烈不同意)- 4(强烈同意),收集学生对环境问题和保护材料的环境敏感性数据,共28个项目,指标为:知识、态度和技能。随后,对数据进行正态性和齐性检验,并使用独立样本t检验进行分析。结果表明,phhl模型对社会科学教育学生对环境问题和环保材料的环境敏感性有显著影响(p (0.009) α(0.05))。实验组环境灵敏度(N-Gain = 13.29)的平均结果高于对照组(N-Gain = 8.75)。这个目标可以通过phhl模型中的语法来实现。进一步的研究建议是,有必要将phl模型与交互式移动学习媒体相结合,作为学生调查和实现问题解决的手段,进一步发展。

Significant and unexpected changes need to be anticipated by all teachers, especially when facing difficult situations in the learning process. This study aims to determine the mediating role of attitude in the correlation between creativity and curiosity regarding the performance of outstanding science teachers. A quantitative causal method was used which involves 100 teachers that were selected using a purposive sampling technique. Collection of research data using four questionnaire instruments with a Likert-scaled were derived from the existing grand theory and met the psychometric properties as a suitable instrument to use. Multiple regression analysis is used to identify the relationship between these variables. The results of the data analysis showed that the creativity affects attitude directly and attitude also affects performance. Other results show that curiosity has a direct effect on performance and has no indirect effect on performance. Meanwhile, other results also explained that the investigated variables are positively correlated with the outstanding science teachers. The results of the study concluded that attitude can act as an effective mediator in the relationship between creativity and performance. Creativity and curiosity are important variables to support the performance of outstanding science teachers. The limitations of this study and discussions were subsequently explained in this article.

Learning design abilities and TPACK are very much needed by prospective science teachers to prepare science learning in the 21st century. The specific objectives of this research were to analyze the improvement of the learning design ability and TPACK possessed by pre-service science teachers after taking lectures with the Project-Based Scaffolding TPACK (PBST) model and analyze the correlation between TPACK and learning design abilities. The research used was quantitative research with non-equivalent control group design. The samples selected were 4 classes of pre-service science teachers who were taking Science Learning Strategy and Design courses. The instrument used in this study consisted of a lesson plan assessment sheet and a TPACK evaluation test. Data analysis used was independent t test, N-Gain test, and bivariate correlation test using SPSS. The results showed that the experimental class obtained an increase in the high category on learning design ability and the medium category on TPACK. After being given PBST model treatment in the experimental class, there is a significant difference in the learning design ability and TPACK between the experimental and control classes. In addition, the results also show that there is a correlation between TPACK and learning design ability. The PBST model is expected to be a solution offer to prepare pre-service science teachers at higher education in line with the demands of 21st century learning based on technology integration.
