This study was conducted to analyze the test instrument used to measure the ability of students in the odd final exam in mathematics. Sampling using purposive sampling technique. These students consist of 398 students. The questions given are in the form of multiple-choice questions with a total of 40 items. The data analysis technique used quantitative descriptive analysis. Data analysis was carried out using the Item Response Theory (IRT) Rasch model approach with the help of QUEST software. The results of the analysis show, from 40 items there are 39 items fit with the Rasch model. Judging from the level of difficulty, items with very difficult categories are 0%, difficult categories are 8 items or 21%, moderate item categories are 23 items or 59%, easy categories are 8 items or 21%, and very easy categories are 0 %. The reliability of the estimatedvalue of the item is 0.95 with a very good category so that it affects the items that fit the model. Thehigher reliability, the more items that fit the model. The reliability of the case estimate value is 0.00with a weak category. This value indicates an inconsistency in the answers of the test takers, whichmeans that the test takers are careless in answering the questions, thus affecting the reliability ofthe questions.

The lack of reliable and valid instruments to assess creative problem-solving (CPS) in elementary students is a primary problem, especially within evolving educational frameworks. Purpose of this Research: This study aimed to examine the validity and reliability of a CPS assessment instrument focusing on the dimensions of originality, completeness, and practicality to develop a more accurate measurement model. Research Methods: Using a quantitative, cross-sectional design, the data were analyzed using Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA). Research Sample: Data were collected from a sample of 150 elementary school students in South Sulawesi Province, Indonesia. Results and Implications: The results indicated that the CPS instrument is best represented by two aspects: originality and completeness, while the practicality aspect was excluded. The implication of this finding is the provision of a refined, valid, and reliable two-factor CPS model. Impact: The impact is that educators now have a more robust tool to accurately measure student creativity, which supports the cultivation of 21st-century skills and informs curriculum development by focusing on empirically supported aspects of creative problem-solving.

This study aims to analyse research trends on children's self-esteem education. This study uses the keywords "self-esteem" and "education" in the Scopus database, using the PRISMA framework and obtaining 772 documents analysed using VOSviewer, Biblioshiny, Microsoft Excel, and Publish or Perish (PoP) to map the results of the analysis with bibliometrics. The analysis results show that research on educational self-esteem from 1975 to 2025 experienced a peak in publication in 2024 and a productive peak in 2014 with an h-index of 16. The last 5 years of research on self-esteem are associated with children's social and psychological dimensions and academic performance. From the results of the systematic literature review, it is known that self-esteem affects children's confidence in their abilities, and this affects children's academic performance at school. Thus, learning that can improve students' self-esteem is supportive, reflective, participatory, problem-solving, and communicative learning, because these five characteristics help students feel valued.

Generally, students still need help working on story-shaped questions. This error is natural, but if it continues, it will harm the mastery of the next material. The ability to solve story questions is closely related to numeracy skills, therefore knowing the location of the difficulties using the revised Newman theorem and the causal factors will help students achieve higher learning outcomes. This research was a quantitative descriptive approach, with the research subjects of junior high school students as many as 152 students. The instruments used were diagnostic tests and questionnaires. Each had an estimated reliability of 0.701 and 0.705 with good qualifications. The results show that students' most frequent types of errors in solving story questions on empirical and theoretical probabilities were 43% transformation errors, 36% comprehension errors, 15% process skill errors and encoding errors by 6%. The specific factors of student errors are not thorough students, being in a hurry, having difficulty understanding the questions, did not master the material, forgetting the formula, hesitating in determining the formula, not re-check the answers, and were unable to write the final project answers/conclusions. Interest and motivation factors as well as society factors are the general factors that most influence the mistakes made by students

This study aims to evaluate the reliability of chemistry laboratory practice assessments for Grade XII senior high school students by applying Generalizability Theory (G-theory) and Decision Study (D-study). A total of 79 students were involved in the research, each randomly assigned to perform one of six available chemistry laboratory practice tasks: electrolytes and nonelectrolytes, exothermic and endothermic reactions, enthalpy of neutralization between HCl and NaOH, acid-base titration, identification of acidic-basic properties, and electrolysis of CuSO₄. Each student was assessed independently by two chemistry teachers based on seven performance criteria: equipment selection, procedure, data reading, analysis, conclusion, cleanliness, and time efficiency. The G-study was conducted using a nested-crossed model in which students were nested within laboratory practice tasks and crossed with raters. The results revealed that variance due to raters (43.2%) and residual error (42.2%) dominated the total score variance, while the variance attributed to students nested within laboratory practice was relatively low (14.6%). The D-study produced a generalizability coefficient (Eρ²) of 0.41 and a dependability index (Φ) of 0.26, indicating low reliability for both relative and absolute decisions. A D-study simulation demonstrated that increasing the number of raters and laboratory practice tasks improved reliability. An optimal configuration of six tasks assessed by nine raters is required to achieve an Eρ² ≥ 0.80. These findings underscore the importance of well-designed assessment systems, consistent rater training, and diverse task coverage to ensure fair and dependable laboratory practice scoring. G-theory and D-study prove to be valuable tools for enhancing the quality of performance-based assessments in science education.

This study addresses the issue of score inconsistency in performance-based assessment (PBA), particularly in creative disciplines where fairness and reliability are crucial. The main objectives of this study were to evaluate the reliability of PBA scores and analyze sources of measurement error using Generalizability Theory (G-Theory). This quantitative study employed a fully crossed (p × r × d) design in an eveningwear construction course. A total of 70 student fashion products were assessed by four assessors consisting of two internal lecturers and two external industry professionals byusing a five-dimensional rubric. Data were collected through standardized scoring sheets and analyzed using linear mixed-effects modeling in R software (lme4 package). Variance components were estimated in the Generalizability Study (G-Study), followed by simulations in the Decision Study (D-Study) to test various assessment configurations. The G-Study results indicated that the largest variance component came from residual error (50.42%), followed by product differences (43.44%), while the contributions of assessors and dimensions were relatively small. The D-Study showed that increasing the number of raters and rubric dimensions significantly increased reliability; a configuration of four raters and five dimensions resulted in a generalizability coefficient of 0.9185. These findings confirm that G-Theory is effective for diagnosing and optimizing reliability in the context of creative assessment. This research provides practical insights for educators in designing fairer and more reliable assessment systems, and opens up opportunities for the application of psychometrics in vocational and design education.

The teaching skills developed by prospective teachers are often repeated in different situations. Therefore, the optimal frequency of microteaching practices may influence both teaching skills and pedagogical content knowledge. This study used a cross-sectional design to compare teaching skills and pedagogical content knowledge among groups based on the frequency of microteaching practices conducted by prospective mathematics teachers. A total of 79 students were randomly selected from three universities in Yogyakarta that implemented microteaching with varying frequencies. These frequencies were classified into four categories: once, twice, three times, and more than three times. Teaching skills were assessed using observation sheets that outlined aspects such as explaining skills, asking questions, providing guidance, providing reinforcement, managing whiteboard use, and regulating body movement (non-verbal cues). Pedagogical content knowledge was measured using a test instrument. Data were analyzed using descriptive statistics and a one-way ANOVA test. The results showed that the frequency of practice has a different impact on teaching skills and pedagogical content knowledge. Prospective teachers who practiced microteaching more than three times significantly differed in their explaining skills, while their providing reinforcement differed significantly from those who practiced at least three times. Conversely, prospective teachers who practiced twice performed similar levels of skill in asking questions, whiteboard management, and regulating body movement compared to those who practiced more frequently. Pedagogical content knowledge of prospective teachers who practiced more than three times was significantly higher than that of those who practiced three or fewer times. These findings suggest that universities should carefully regulate the frequency of microteaching practices to optimize students' teaching skills and pedagogical content knowledge in mathematics education for those who aspire to become effective mathematics teachers. These findings suggest that universities should carefully regulate the frequency of microteaching practices to optimize students' teaching skills and pedagogical content knowledge in mathematics education students who aspire to become effective mathematics teachers.

Creativity is a key 21st-century competence, especially vital in mathematics education. This study presents a systematic literature review and thematic mapping analysis of mathematical creativity from 2016 to 2025, using data from the Scopus database analyzed via RStudio Biblioshiny and the PRISMA framework. It explores three core questions: the evolution of research themes in mathematical creativity, the thematic linkage between creative thinking and attitudes toward mathematics, and pedagogical approaches that connect both constructs. Bibliometric analysis reveals mathematical creativity as a central and evolving theme, prominently positioned in co-occurrence networks and thematic quadrants. Creative thinking and attitudes toward mathematics appear within the same thematic cluster, indicating a strong cognitive-affective connection. Emerging research also identifies ethnic factors and environmental literacy as potential mediators in this relationship. These findings suggest that Realistic Mathematics Education (RME), particularly models incorporating ethnic contexts and environmental themes, may serve as effective pedagogical strategies. Such approaches have the potential to enhance both creative thinking and positive attitudes toward mathematics, contributing meaningfully to the broader discourse on mathematical creativity.
