The purposes of this research are: 1) to compare two equalizing tests conducted with Hebara and Stocking Lord method; 2) to describe the characteristics of each equalizing test method using windows’ IRTEQ program. This research employs a participatory approach as the data are collected through questionnaires based on the National Examination Administration of 2018. The samples are classified into group A and group B respectively by 449 and 502 respondents. This paper discusses how to equalize shared items using the anchor method with a set of instruments in the forms of 35 questionnaire items and 6 shared items. In addition, the researcher also uses PARSCALE to estimate each respondent’s skills and each item’s characteristics. The shared items are eventually equalized using IRTEQ program. The results show that there is a significant difference between those conducted using Haebara method (0.592) which produces bigger mean-sigma value and Stocking & Lord (0.00213). Thus, the results show that the shared testing items may improve respondents’ discrimination and increase the difficulty level (parameter b). Due to the availability of shared items, it is good and appropriate to equalize two different tests on different theta skills.

The Computer has occupied a comprehensive coverage, especially in education scopes, including in learning-teaching processes, testing, and evaluating. This research aimed to develop computerized adaptive testing (CAT) to measure physics higher-order thinking skills (HOTS), namely PhysTHOTS-CAT. The Research Development used the 4-D developmental model carrying the four phases of define, design, development, and dissemination (4D) developed by Thiagarajan. This testing instrument can give the item test based on the student’s abilities. The research phases include (1) needs analysis and definition, (2) development design (3) development of CAT and assemble the test items into CAT, (4) validation by experts, and (5) feasibility try-out. The findings show that PhysTHOTS-CAT is valid to measure physics HOTS of the 10th-grade students of Senior High School according to 82.28% of teachers and students assessment on PhysTHOTS-CAT content and media. Therefore, it can conclude that PhysTHOTS-CAT can be used and feasible to measure physics HOTS of the 10th-grade students of the Senior High School.

The purpose of this research is: 1) to develop the model and produce the assessment of creative curriculum-based learning program multiple intelligences (MI), 2) to know the characteristics and impacts of developed product models. Research using multi-years by method R & D (Research and Development) with two phases; First phase: 1) Preliminary survey stage, 2) definition stage, 3) design phase, 4) trial stage, and 5) development stage; The second phase: 1) the instrument design stage through the Forum Group Discussion, 2) the product trial phase of 100 children in Sleman Regency, 3) wide-scale implementation of 200 children in Yogyakarta Province, 4) the evaluation phase with construct analysis and achievement of research subjects' performance, 5 ) the stage of measuring the effectiveness of the product with user perception. The subject comprises 200 children of early childhood and 20 kindergarten teachers in 10 kindergartens in the Yogyakarta province in Indonesia, by the approach of Reflective Measurement Theory (RMT). The results showed that: 1) the MI-based creative curriculum assessment model was developed to meet valid, reliable and conformity criteria of an empirical data model, 2) The implementation of the assessment model had fulfilled the requirements worthy of using three criteria  aspect; 1) The results of the assessment using creative instruments based on multiple intelligences on children get "very good" results, 2) the readiness of the teacher in learning is included in the "good" category; 3) teacher performance appraisal shows the "very good" category, and 4) the benefits of the products developed are in the "very good" category. It was concluded that the developed product had tested empirically and practically so that it was useful in learning in early childhood.

In this research, the influence of the Coronavirus disease (COVID-19) pandemic on 9th grade students’ mathematics achievement is analyzed through quantitative and qualitative methods. A posttest only with control group design was used to compare the mathematics marks of 9th grade students from the previous school year (before the pandemic, control group) and the current school year (during the pandemic, experimental group). Seventy-three students from a public high school in Spain attending class on alternate days participated in the study. Three focus group sessions were held with students, and five semi-structured interviews were conducted—two with teachers and three with students’ families. Results show statistically significant differences in students’ mathematics achievement, with students enrolled in 9th grade the previous (pre-pandemic) year outscoring their peers currently enrolled in 9th grade (during the pandemic) by 22.17%. An overall negative effect size of Hedge’s g = -1.11 was reported. Although significant statistical differences between groups were reported for both male and female students, the effect was 42.31% larger for male students (Hedge’s g = -1.11) than for females (Hedge’s g = -0.78). The qualitative information supported the quantitative results. Changes in educational settings, students’ lack of motivation, monotony, and students’ level of responsibility were qualitatively reported as factors that may explain this phenomenon. The main conclusion of this study is that the COVID-19 pandemic may be significantly and negatively affecting 9th grade students’ mathematics achievement.
