Abstract

The ability to solve problems and apply scientific processes is a critical component of 21st-century education, especially within the context of the Indonesian "Merdeka" curriculum, which promotes independent and adaptive learning. However, traditional assessment methods fail to capture these competencies adequately. This study aims to determine the feasibility of an assessment instrument designed to measure high school students' problem-solving ability and science process skills. The instrument was developed using Istiyono’s test development model and focused on the test trial stage, which involves expert validation, empirical analysis, reliability testing, and item difficulty analysis. Using Istiyono’s model, the development focused on expert validation, empirical testing, and item analysis. A total of 252 students from six high schools in Yogyakarta and surrounding regions participated in the study. The content validity was assessed using Aiken's V, showing all items to be valid. Content validity, evaluated using Aiken’s V, indicated all items were valid. Empirical validation using the QUEST program yielded INFIT MNSQ values of 0.99 ± 0.81 for problem-solving and 1.01 ± 0.21 for science process skills, confirming item validity. Reliability coefficients ranged from 0.61 to 0.97, indicating high reliability. The difficulty level of items was distributed across easy, medium, and difficult categories. These findings support the feasibility of the assessment instrument in evaluating students’ higher-order thinking skills. The findings demonstrated the instrument’s suitability for assessing complex cognitive and inquiry-based skills. The validated instrument offers practical implications for educators to improve learning through formative assessment aligned with curriculum goals.

Abstract

Exposure to vehicle emissions, particularly carbon monoxide (CO), during pregnancy has been identified as a potential factor contributing to low birth weight in infants. CO's impact on the body involves binding with hemoglobin (Hb) in red blood cells, leading to placental dysfunction and alterations in oxygen flow efficiency to the uteroplacental. Such disruptions can adversely affect fetal growth. This study focuses on Makassar City, a rapidly developing urban area experiencing substantial growth in infrastructure and transportation. This research aims to assess the impact of carbon monoxide exposure on birth weight in pregnant women residing in Makassar City. The method of this study is a quantitative approach employing a descriptive cross-sectional design, which was adopted for this study. The research sample consisted of 120 pregnant women categorized based on their CO exposure levels—30 with low exposure, 60 with moderate exposure, and 30 with high exposure. Simple random sampling was utilized for participant selection. CO levels were measured using the Adalog 7000 multi-gas monitor. Data analysis included One Sample ANOVA and Linear Regression. The results show that data analysis indicated that pregnant women with low CO exposure had an average birth weight of 3110.83 grams. In contrast, those with moderate and high CO exposure exhibited average birth weights of 2840.33 grams and 2667.33 grams, respectively. The regression coefficient for CO exposure was -221,750, indicating that a 1 µm increase in carbon monoxide gas correlated with a decrease in birth weight by -221,750. The conclusion is that pregnant women who are exposed to high and moderate carbon monoxide gas during pregnancy had an effect on birth weight than mothers who are exposed to low carbon monoxide gas. Future research is needed to measure CO levels in the blood of pregnant women about birth weight.

Abstract

This study aims to develop an instrument for teachers’ perceptions of differentiated instruction by adopting Oriondo and Antonio's instrument development model. This study involves three stages of development: instrument planning, pilot testing, and measurement. The respondents involved were 152 subject teachers at the secondary school level. The instrument developed contains differentiated instruction principles: learning environment, quality curriculum, responsive teaching, continuous assessment, and leadership and routines. A combination of the Guttman Scale and Item Response Theory was used to measure teachers' perceptions, which gave significant results. The analysis results show that most instrument items follow the model used, but some items require adjustment. The implication of this study is the importance of developing valid and reliable instruments to measure teachers' perceptions of differentiated instruction. The findings can contribute to improving classroom learning practices and student learning outcomes. Thus, this study provides a strong foundation for the development of teacher professionalism and the overall improvement of education quality.

Abstract

This research aims to (1) develop feasible learning tools for the kinetic theory of gases and (2) create effective physics learning tools for students. The research employs the ADDIE model. The data analysis to evaluate the feasibility and practicality of the learning tools uses a standard scale, while the validity of the question instrument is assessed using Aiken's V and item analysis with the Partial Credit Model (PCM). To measure the effectiveness of the tools in enhancing students' computational thinking skills, a repeated-measures MANOVA is conducted using the General Linear Model (GLM) with a significance level of 0.05. The findings indicate that (1) the developed learning tools are deemed feasible for use in improving computational thinking skills, as assessed by media experts, material experts, and practitioners. Moreover, (2) the analysis shows a significance value of 0.000 < 0.05, meaning there is a noticeable difference in computational thinking abilities between the experimental and control groups. Additionally, the effect size obtained was 0.813, which is categorized as large. These results suggest that the learning tools developed are both feasible and effective. In conclusion, this research demonstrates the potential of these tools to enhance students' computational thinking abilities in physics education, specifically in the context of the kinetic theory of gases, making them a valuable resource for future learning activities.

Abstract

This study addresses the lack of specialized diagnostic instruments capable of pinpointing specific cognitive failures in physics data literacy, particularly within Thermodynamics. To bridge this gap, a Distractor-Based Cognitive Diagnostic Test (DB-CDT) was developed and validated for eleventh-grade high school students in Yogyakarta. Utilizing a Research and Development (R&D) approach with the ADDIE framework, the instrument was built upon the DINA (Deterministic Input, Noisy-AND Gate) cognitive diagnostic model. Expert validation by three specialists yielded an excellent average V-Aiken value of 1.00. Empirical testing on a sample of 540 students across high, medium, and low-tier schools confirmed high psychometric quality: an average INFIT MNSQ of 1.00 (within the 0.77–1.30 range), item difficulty between -2 and +2, and high reliability (0.92). DB-CDT distinguishes itself by using a Q-Matrix to link specific distractors to cognitive errors, such as failures in sign conversion or process interpretation. Analysis of student profiles revealed that the experimental group—utilizing targeted diagnostic feedback—achieved superior mastery in analyzing (96.6%) and interpreting data (90%), whereas the control group, receiving conventional assessment, struggled significantly with inference and synthesis. Theoretically, this research advances the application of Cognitive Diagnostic Models in physics education. Practically, it provides educators with a sensitive tool to profile individual student weaknesses, allowing for more focused instructional interventions in complex scientific topics.

Abstract

The implementation of HOTS in the learning process is considered capable of improving the quality of education in Indonesia. However, in online learning conditions, there are many obstacles and limitations to training HOTS in Biology lesson. This study aims to describe biology teachers' knowledge, preparation, and implementation of HOTS training during online learning. This study uses a qualitative approach to the type of phenomenology. This study involved 12 Biology teachers at SMA and SMK in West Java. The data collection technique is carried out through interviews via WhatsApp Call. The data analysis technique used is through reduction, data review, and conclusions drawing. Based on the results of data analysis, it was found that the teacher’s understanding of HOTS learning is still weak, and the implementation of HOTS training during online learning is still not optimal. The most widely used learning model is Problem based Learning. The constraint implementation of online HOTS training is inseparable from the online learning barriers, but teachers also continue to try to handle these barriers with various solutions.

Abstract

Physics learning anxiety is an affective factor that can influence students’ readiness to learn, concentration, and academic achievement. This study aimed to develop a valid and reliable instrument to measure physics learning anxiety among senior high school students. The development procedure followed the stages of research and development (R&D), including preliminary study, construction of dimensions and indicators, item development, content validation by five experts, limited trial testing (N = 30), and large-scale testing (N = 150). Content validity was analyzed using the Content Validity Ratio (CVR) and Content Validity Index (CVI). Empirical validity was determined through corrected item–total correlation (r_it), while reliability was assessed using Cronbach’s Alpha. The results showed that the instrument demonstrated strong content validity, indicated by a high CVI value. Empirical testing revealed three items (25, 34, and 37) that did not meet the r_it ≥ 0.30 criterion and were therefore removed. The final instrument consisted of 37 items with very high reliability (α = 0.939). This instrument is suitable for use as a measurement tool for assessing physics learning anxiety among senior high school students.
