Inadequate science literacy and independent learning hinder students' ability to analyze scientific information. This study aimed to develop and validate a measurement instrument to assess science literacy and independent learning skills among high school students. The instrument was piloted with 20 twelfth-grade students at SMAN 03 Kota Yogyakarta to assess its reliability and validity. The validated instrument was administered to 20 eleventh-grade students at the same school to identify the profiles of these two skills and explore their relationship in the context of the nervous system. The validity analysis demonstrated that both the science literacy and independent learning instruments exhibited strong validity. Pearson correlation analysis revealed that 20 items in the independent learning questionnaire were strongly correlated with the total score. Rasch analysis of the science literacy test indicated low infit mean square values, appropriate p-values, and high point biserial values, suggesting well-functioning items. Cronbach's alpha reliability coefficients for both instruments were excellent. The profile analysis revealed a discrepancy, with many students showing high independent learning levels but low science literacy scores on the nervous system topic. This gap suggests that even students capable of independent learning may face challenges in grasping specific scientific concepts.

This type of research is Quasi-Experimental with pre-test-post-test experiments and a control group design. The researcher conducted the research because most of the students who became respondents considered biotechnology material less attractive, so students' understanding and activeness could have been more optimal in the learning process. The research samples were 72 students of class X MIPA at SMA Negeri 2 Kota Serang, Banten. The research sample was divided into two groups: the experimental group that applied the PBL integrated RMS model and the control group that applied the PBL model. The research instruments used were biological literacy ability tests and critical thinking ability tests. Biological literacy skills were measured using biological literacy-based multiple-choice test instruments, while critical thinking skills were measured using essay test instruments. The hypothesis test used was MANOVA statistical analysis. The results of statistical tests showed a significant effect of PBL integrated with RMS on biological literacy and critical thinking skills on biotechnology material with a significance value of 0.000 < α. Students with an integrated RMS learning model are more effective than those with a PBL learning model, which is indicated by the post-test value being higher than the pre-test value. This research contributes to the field of biology education by showing that the PBL learning model integrated with RMS can be an effective alternative learning model to improve students' biological literacy and critical thinking skills. The findings of this study are expected to be useful for biology teachers

Mon, 11 Nov 2024 00:00:00 +0700

Photosynthesis is a foundational biological topic which often presents learning difficulties because of its complex processes and common misconceptions. Hence, valid and reliable diagnostic tool is needed to identify misconceptions and eventually guide development of instructional interventions. This study aimed to develop a valid and reliable concept inventory test to assess junior high school students' understanding of photosynthesis. It was developed to identify common misconceptions and provide valuable insights into students' cognitive processes. This 20-item concept inventory test crafted with the aid of a table of specifications was based on Revised Bloom’s taxonomy of cognitive domain and administered to 355 junior high school students. In validation, results displayed high content validity with a mean of 4.85 and an average Aiken’s validity coefficient of 0.96. It also falls in the category moderately difficult with the test difficulty of 0.49, and test discrimination of 0.45. In item classification, 18 items were retained (16 accepted, 2 needs revisions) and while reliability test was employed through Cronbach’s alpha (α=0.70) indicating sufficient measure of good and internal consistency. Distractor analysis was also performed to determine possible source of misconception per item. The concept inventory test is found to be a good classroom test with some items to be improved and offers educators a valuable resource for diagnosing student misconceptions and enhancing their teaching practices.

In biology learning, test instruments are essential for assessing students' understanding of complex concepts. A test instrument is a crucial factor in learning evaluation; however, its implementation remains minimal. This descriptive quantitative study aims to analyze the quality of test items using the classical approach in terms of validity, reliability, difficulty index, discrimination power, distractor effectiveness, and the Rasch model analysis. The data consists of 30 multiple-choice questions from a biology midterm exam administered to 40 students. Classical test data analysis uses Microsoft Excel, while Rasch model analysis uses Winsteps software. The validity test results from both approaches show 14 valid questions and 16 invalid ones. The reliability scores are 0.619 (adequate) for the classical approach's Cronbach's Alpha, 0.85 (good) for the Rasch model, and 0.65 (weak) for personal reliability. The classical test theory and the Rasch model categorize item difficulty into four levels. The classical approach produces five categories for item discrimination, while the Rasch model identifies three groups based on the item separation index (H=3.45) and two groups based on respondent ability (H=1.96). Distractor effectiveness shows 93.3% functional distractors in the classical test and 80% in the Rasch model. The Rasch model offers greater precision in measuring student ability and detecting bias. Both models should be integrated for comprehensive item analysis. Future tests should focus on improving invalid items and the quality of distractors.

Technological Pedagogical and Content Knowledge (TPACK) is very important in the process of developing professional teacher competencies in the era of the Industrial Revolution 4.0. The purpose of this study was to determine the profile of biology teachers TPACK on the classification of living things. This research is a descriptive study using a qualitative approach. Data collection techniques were carried out using questionnaires, CoRe&TPaP-eRs, and interviews. The sample was compiled using a saturated sampling technique with a total of ten respondents. The results indicated that biology teachers' TPACK skills must be improved. The results of the questionnaire consisting of 7 TPACK components, reaching 70.11% were categorized as good. The TK, PK, CK, and PCK components are in the excellent category, while the TCK, TPK, and TPACK components are still in the good category. The results of the CoRe & TPaP-eRs instrument covering 5 aspects show that the average of teacher’s TPACK reached 41%, in the Growing-TPACK category. The TPACK of biology teachers based on teaching experience is not so different. The results show that the length of teaching experience is not directly proportional to the growth of TPACK skills.

In this century, humans are required to be able to adapt to the development of the times and are required to be able to answering and solving all problems that arise. One of the abilities that must be developed to face these challenges, namely the ability in the field of creativity. The research’s purpose is (1) to determine the differences in students' creative thinking abilities using the PjBL learning model and the PjBL-STEM learning model on class X environmental change material, (2) to determine students' responses to the PjBL-STEM learning model. This research used a posttest only control group design. The population used is class X1-X10 SMA Al Islam 1 Surakarta for the 2023/2024 academic year, a total of 384 students. The sampling technique used cluster random sampling, class X7 with 38 students as the control class using the project-based learning (PjBL) learning model and class X3 with 40 students as an experimental class using an integrated STEM with project-based learning (PjBL) learning model. Data collection was carried out using documentation, tests regarding creative thinking abilities, and student response questionnaires. The data analysis technique was carried out using a one-way t test. The research instruments are teaching modules, LKPD, creative thinking skills questions, and student response questionnaires. The instrument validation technique is carried out using validity tests and reliability tests. The results of the research show that (1) there is a significant difference in students' creative thinking abilities on environmental change material using the PjBL-STEM learning model, (2) students' responses to the PjBL-STEM learning model are included in the positive category.
