Abstract

This study aimed to eval_uate the quality of test items in a science learning assessment instrument designed to measure students' conceptual understanding of the human body system using Rasch model analysis. A quantitative descriptive research design was employed, involving 100 junior high school students as participants. These students completed a conceptual understanding test consisting of 35 multiple-choice items. The Rasch model was applied using Winsteps software to assess item fit, analyze the person-item distribution through the Wright Map, and eval_uate the overall validity and reliability of the instrument. The analysis results showed that all test items met the Rasch model criteria, indicating their suitability for assessing students' conceptual understanding. The instrument provided an item reliability score of 0.85, reflecting strong internal consistency, while the item separation index of 2.38 confirmed its capability to distinguish items based on difficulty levels. The Wright Map further illustrated a proper alignment between item difficulty and student ability, ensuring fair measurement across varying levels of proficiency. These findings confirmed that the developed instrument was valid and reliable, making it a valuable tool for both eval_uative and diagnostic purposes in science education

Abstract

Background: Learning biology has material and concepts that must be understood by students, besides that there is material that is abstract in nature which makes students feel difficult in understanding it. This can cause student academic stress during the biology learning process. Students who experience stress will certainly feel a loss in the field of learning if they are not able to manage stress quickly and adequately. This research was conducted by analyzing the level of academic stress caused by five factors, namely motivation, self-confidence, anxiety, the education system, and teachers. Academic stress experienced by students is then categorized into three categories, namely mild stress, moderate stress, and severe stress. Methods: The research method used was a survey (expost facto) with instruments in the form of a questionnaire with nine choice scales and interviews. The population in this study were teenage students aged 16-18 years with a sample of 54 students from 3 schools with certain characteristics. Results: The results showed that students experienced academic stress caused by five factors, but with different categories. Students who experience academic stress in the severe category are generally caused by factors of motivation, self-confidence, the education system and teachers. Conclusion: While the anxiety factor only causes academic stress in the mild and moderate categories.

Abstract

Although the relationship between student motivation, self-perception, and achievement in science education is well established, there is still a lack of focused studies on these aspects at the lower secondary level, particularly in private school settings where student demographics and learning environments may pose unique challenges. The purpose of this study is to: (1) assess lower secondary students' motivation and self-concept in scientific learning; and (2), using correlational analysis and qualitative feedback, determine ways to improve these aspects. Using a quantitative descriptive survey design, this study assessed 60 grade 7-9 students from a private lower secondary school. The Students’ Motivation Toward Science Learning (SMTSL) and adapted Chemistry Self-Concept Inventory (CSCI) measured motivation and self-concept, respectively. Data analysis included mean scores for both variables and Spearman’s rank correlation (accounting for Liker-scale ordinality and non-normal distributions). A moderate-high level of motivation (Active learning strategies [ALS]=4.0-4.1 highest, Performance Goal [PG]=2.8-3.1 lowest) and self-concept (Positive Perception of Science Self Concept [PSSC]=3.8-3.9 highest, Mathematic Self-Concept [MSC]=2.9-3.2 lowest) with moderate positive correlation (r = 0.572, p < 0.001) underscores that self-concept and motivation are interrelated, suggests interventions should simultaneously promote active learning (to enhance ALS) while addressing mathematical confidence (to improve MSC). These findings suggest that teachers can boost engagement through active learning and confidence-building strategies, while school and policymakers should design targete interventions to support students with low scientific confidence and high performance pressure.

Abstract

Visual representation is important for scientific communication. One form of visual representation is a diagram. When representing diagrams, there are still students who fail to read labels or titles, misunderstand color codes, or follow arrows in the wrong direction. The aim of this research is to analyze students' ability to visually represent and interpret the Bryophyta life cycle diagram. The visual representations analyzed are internal and external visual representations. This study uses a descriptive approach involving one biology teacher and 33 students from grades X, XI, and XII at one of the high schools in the city of Bandung. Data were obtained through worksheets and semi-structured interviews. Internal visual representation is obtained from the activity of reading and re-representing the available diagrams, while external visual representation is obtained from the activity of redrawing the Bryophyta diagram based on one's own understanding. Assessment is conducted based on three main indicators: the number of phases, the sequence of phases, and the accuracy of phase descriptions. Scores are converted into percentages and categorized into five levels of proficiency: very good, good, moderate, poor, and very poor. The analysis results show that the internal visual representation of students in grades X, XI, and XII falls into the poor category, while the external visual representation of students in grades X and XI falls into the good category, and grade XII falls into the moderate category. The analysis also shows a relationship between visual representation and prior knowledge. These findings have important implications for the development of visual-based learning and mapping students' difficulties in understanding diagrams.

Abstract

Understanding students' perceptions of socio-scientific issues (SSI), particularly in the context of biology, is essential for developing effective teaching strategies. This study analyzes students’ perceptions of SSI in biology, involving 360 participants from 10th- and 11th-grade classes at a high school in Majalengka, West Java, Indonesia. The participants, aged 16 to 17 years, were equally divided between the two grade levels. Data were collected using a 24-item survey questionnaire based on a five-point Likert scale. The results show an overall mean perception score of 3.31, indicating that students generally hold a neutral perception of SSI in biology. A weak correlation was observed between students’ overall perceptions and SSI in biology, with a p-value of 0.08 and an r-value of 0.02. Further analysis revealed minor differences in perceptions based on grade level and gender, with 10th-grade students scoring an average of 3.30 and 11th-grade students scoring 3.32. Male students averaged 3.28, while female students averaged 3.34. These findings suggest that although students exhibit neutral perceptions of SSI in biology, many struggle to connect biological concepts to real-life contexts. This highlights the need for further research to identify factors influencing students’ perceptions and to explore alternative learning models for improving understanding and engagement with SSI in biology.

Abstract

Education plays a critical role in developing the potential of each individual, and the quality of the teaching and learning process is vital for the success of the education undertaken by students. Innovative learning designs that meet student needs are required. Genetic material in biology, which is complex and conceptual, requires deep understanding. Therefore, it is important for educators to use teaching strategies that allow students to better understand genetic concepts. The purpose of this study is to evaluate genetic teaching strategies including curriculum analysis, approaches, and the application of various models, methods, and media in learning. This research method is qualitative with a descriptive approach, aiming to describe current genetic teaching practices, including the use of TPACK by teachers. Data was collected through literature study with stages such as data collection, organization, analysis, interpretation, and conclusion with descriptive qualitative data analysis. The analysis results were verified by experts. The findings show that teachers have implemented various approaches, models, methods, and learning media. The success of the learning process greatly depends on effective teacher planning so that students can clearly understand the material. These findings provide useful information for teachers to implement TPACK in genetics learning.

Abstract

This study aims to analyze the implementation of Total Quality Management (TQM) in improving patient satisfaction at RSUD dr. RM. Pratomo Bagansiapiapi. The background of this research stems from the recognition that patient satisfaction is a key indicator of a hospital's success in delivering high-quality, user-oriented healthcare services. A qualitative descriptive method with a purposive sampling approach was employed. The informants consisted of the Hospital Director, Head of Medical Services, Head of Medical and Non-Medical Support Services, patients, and patients’ families. Data were collected through in-depth interviews, observation, and documentation. The findings reveal that the implementation of TQM at the hospital has covered several essential elements, including customer focus, quality obsession, scientific approach, long-term commitment, teamwork, continuous improvement, education and training, controlled freedom, unity of purpose, and employee involvement and empowerment. However, challenges remain, such as limited resources, resistance to change, and suboptimal information management systems. These factors affect the overall level of patient satisfaction. The study affirms that TQM is not merely a managerial tool but a strategic framework that requires a collaborative and adaptive work culture. Strengthening managerial commitment, enhancing human resource capacity, and optimizing quality evaluation systems are crucial ongoing agendas to improve service quality and patient satisfaction comprehensively.Keywords: Total Quality Management (TQM), Service Quality, RSUD dr.

Abstract

Cognitive load can be measured, one of which is by emotions through facial expressions during learning. This research aims to develop learning media by integrating artificial intelligence (AI) that is able to detect the emotions of prospective teachers during genetics lectures. Using AI technology, the system can evaluate students' cognitive load in real-time through facial expression analysis. This learning media is equipped with emotion detection features, interactive learning materials, and an informative dashboard to monitor student learning progress. This research is a development research that refers to the Borg & Gall model. The data collection technique is in the form of questionnaires and questions integrated into AI media that detects student emotions, which are then analyzed using machine learning algorithms to identify the level of cognitive load during the lecture session. The results of the study showed that this learning medium was able to identify the emotional expression of each student in the genetics of mendelism with a percentage of 61.64% (surprised-happy) describing a moderately low-very low cognitive load, and 38.42% (sad-angry) describing a high cognitive load. So that with the acquisition of this data, it is known that more than 50% of students' emotional recordings (low cognitive load) can follow and understand the information obtained in the Mendelism genetics lecture. The application of this technology is expected to improve the quality of learning and help students achieve a better understanding of genetics courses.
