Abstract: This research aimed to evaluate the students’ conceptual understanding and to diagnose the students’ preconceptions in elaborating the particle characteristics of matter by development of diagnostic instrument as well as Rasch model response pattern analysis approach. Data were acquired by 25 multiple-choice written test items distributed to 987 students in North Sulawesi, Indonesia. Analysis on diagnostic test items response pattern was conducted in three steps: 1) conversion of raw score to a homogenous interval unit and effectiveness analysis of measurement instruments 2) measurement of disparity of students’ conceptual understanding and 3) diagnosis of students’ preconception by estimation of item response pattern. The result generated information on the diagnostic and summative measurement on students’ conceptual understanding in elaborating the topic information also acts as empirical evidence on the measurement’s reliability and validity. Moreover, the result discovered a significant disparity between students’ conceptual understanding based on their educational level. It was found that the distractor item response pattern tended to be consistent, indicating a certain tendency of resistant preconception pattern. The findings are expected to be a recommendation for future researchers and educational practitioners that integrate diagnostic and summative measurement with Rasch model in evaluating conceptual understanding and diagnosing misconception. Keywords: conceptual understanding, item response, particle of matter, Rasch model

Abstract: style="text-align: justify " This study aimed to find the Classical Test Theory (CTT) and Modern Test Theory (MTT) item parameters of the Differential Aptitude Test (DAT) and examined their comparability of them. The item parameters being studied are difficulty level and discrimination index. 5.024 data of the result sub-test DAT were documented by the Department of Psychology and Guidance and Counselling bureau. The parameter of classical and modern test items was estimated and correlated by examining the comparability between parameters. The results show that there is a significant correlation between item parameter estimates. The Rasch and IRT 1-PL models have the highest correlation toward CTT regarding the item difficulty level. In contrast, model 2-PL has the highest correlation toward CTT in the item discrimination index. Overall, the study concluded that CTT and MTT were comparable in estimating item parameters of DAT and thus could be used independently or complementary in developing DAT.

Abstract: In the context of teacher professional development and teacher certification, an objective measurement of teachers’ Pedagogical Content Knowledge (PCK) is requried. This research is a case study to measure teachers’ PCK within prospective middle school science teachers participating in an Indonesian teacher professional development program. The study used quantitative approach which involved multirater assessment analysed by Many-Facet Rasch Model (MFRM) to assess teachers’ PCK in teaching a specific topic, i.e. “The Particulate Nature of Matter” (PNM). Researchers developed a rubric for items to measure teachers’ enactment PCK for teaching that specific topic. The MFRM analysis of the data revealed item reliability, item validity, separation and unidimensionality fall within good category. The findings show prospective teachers need to improve their PCK specifically in terms of “knowledge of instructional strategies and representations for teaching science” dimension. However, for knowledge of science curriculum and knowledge of students’ understanding in science dimension, the findings show that the participants were competent.

Abstract: Background. Inappropriate anthropometric measurements of infants and toddlers lead to a misclassification in nutritional status and loss of important interventions. Considering the practice conducted in this program within a country, its impact on millions of children must be considered. This study assesses the ability of community health volunteers (CHVs) before and after anthropometric training on infants and toddlers. Methods. This study used a quantitative approach with a quasiexperimental and pretest-posttest design. The pre- and posttraining assessments of CHVs were conducted by standardized trainers using instruments developed according to WHO standards. There were 11 and 13 statement items for infants’ and toddlers’ indicators of assessment in anthropometric measurements, respectively. The result of the assessment was then analyzed using Rasch modeling with stacking and racking data analysis techniques. Results. The CHVs’ skills before training were far from adequate. Although widely varied, all trainees improved their abilities. Stacking analysis showed that the skills of all CHVs in measuring infants and toddlers increased by 2.68 and 3.34 logits ( p 0.01 ), respectively. Racking analysis showed a decrease in the perceived difficulty of all items by 2.61 and 3.07 logits for infant and toddler measurements, respectively ( p 0.01 ). The results of the racking analysis showed that the difficulty in measuring the anthropometrics of infants decreased more than that of toddlers. Conclusions. CHVs’ capacity to monitor child growth must be refreshed regularly. Standardized and proper training and assessment were developed to make CHVs reliable in taking anthropometric measurements of infants and toddlers.

Abstract: Teaching and learning are being transformed by digital technology, where the present generation of students, termed millennials, are more adept with the increasingly digitalised world we live in. Following this, lecturers and institutions are adapting and adopting a blended learning model across disciplines, which now commands an entire domain of research and application. However, questions remain about how ready students are for a blended learning model of instruction. The purpose of this study is to investigate students’ readiness for blended learning in a leading Malaysian private higher education institution. This study used a non-experimental quantitative research design. Data were gathered from a s le of 274 pre-university and undergraduate students using the blended learning readiness engagement questionnaire. Data was analysed using WINSTEPS Rasch model measurement software to determine the validity and reliability of the instrument. Descriptive statistics (mean and standard deviation) scores, (logit) value of the item and (logit) value of a person was used to examine students’ readiness for a blended learning model of instruction and specifically assess their readiness based on gender, age, ethnicity and field of study. Findings indicate that students were ready for blended learning. Further analysis indicated there were differences in students’ readiness for blended learning based on gender, age, ethnicity and field of study. This study provides insight into students’ readiness towards blended learning in a leading Malaysian private higher education institution, discusses implications for blended learning practices and offers recommendations for future research.

Abstract: The 50-item International Personality Item Pool version of the Big Five Markers (IPIP-BFM) is an open-source and widely used measure of the big five personality traits. A short version of this measure (IPIP-BFM-25) has been developed using the classical test theory approach. No study was performed to examine the psychometric properties of a longer and shorter version of IPIP-BFM Indonesia using modern test theory. This study aimed to evaluate the psychometric properties of the Indonesian version of IPIP-BFM as well as IPIP-BFM-25 using Rasch analysis. The analysis was conducted in order to test their dimensionality, rating scale functioning, item properties, person responses, targeting, reliability, and item bias on 1003 Indonesian s les. The findings showed that both IPIP-BFM and IPIP-BFM-25 Indonesia have some adequate psychometric properties, especially regarding category function, item properties, reliability, and item bias. However, the emotional stability and intellect scales did not meet the assumption of unidimensionality, and all items on the scales were too easy to endorse by participants. In general, longer measures outperformed shorter measures in terms of person separation and reliability. Further testing and refinement must be conducted.

Abstract: To date, there are abundant studies on statistical reasoning in descriptive statistics and inferential statistics. Nevertheless, the types of statistical reasoning assessments used in those studies are different from each other. Hence, this qualitative meta-analysis is aimed to explore the methods utilized in assessing statistical reasoning among students from all levels in descriptive statistics. A total of 36 studies on reasoning about measures of central tendency, variability and distribution were found and reviewed in this paper. It was noticed that six major types of methods were employed to assess students’ statistical reasoning in descriptive statistics, namely interview, survey or questionnaire, tasks, tests, minute paper, and teaching. This study contributes considerably to the statistical reasoning area as it provides new information on statistical reasoning in descriptive statistics. For future studies, some recommendations are proposed to improve statistical reasoning assessments.

Abstract: The purpose of this paper is to investigate the degree to which the different attributes of Islamic banks in Indonesia are preferred by the community. This paper uses a quantitative approach by applying Rasch analysis to measure the relative importance of 18 attributes of Islamic banks to the community. The data were collected by questionnaires, which were distributed online and completed by 345 respondents. In addition to the Rasch model, the preference of attributes was measured by a statistical inference test, using “SPSS” software, which employs binary logic regression related to the agreement between the performance of attributes and expectations. The instrument used in this study showed good reliability, and its validity fits the expected model. The results show that the assurance of financial security, friendliness and the application of Islamic principles in their operations are the most important attributes to be considered when people choose an Islamic bank. The degree of importance placed by the community on the various attributes of Islamic banks will have an effect upon the actual and perceived quality of those attributes. An increase in the community’s preference for a particular attribute will eventually be followed by an increased agreement between the actual performance of that attribute and the community’s expectation. The varied profiles of in idual respondents were not explored fully: this research relies solely on quantitative analysis. So, there is no empirical information to inform the Islamic banks as to which segments of the community should be the focus of their promotional activities. The use of Rasch analysis to measure the community’s preference for various attributes of Islamic banks has not been done previously.

Abstract: Universities have shifted from face-to-face learning environments to e-learning in response to the COVID-19 pandemic. However, the sudden change to online teaching has raised concerns among lecturers about students' readiness for e-learning. This study investigates students' readiness for e-learning during the COVID-19 pandemic and specifically assesses any significant differences between students' gender, age, ethnicity, level of education, field of study and their readiness for an e-learning environment. The study employed a non-experimental quantitative research design. Data were gathered from a s le of 298 undergraduate and 101 postgraduate students. WINSTEPS Rasch model measurement software was used to determine the reliability and validity of the research instrument. Descriptive, inferential statistics and differential item functioning (DIF) test were used to assess students' readiness for an e-learning mode of instruction with the latter specifically analysing students' demographic factors and their readiness for an e-learning environment. Findings identified that most students are ready for an e-learning mode of instruction. Further analysis indicated that there were differences in students' readiness for e-learning based on their demographic profiles. This study provides insights on students' readiness towards e-learning, discusses implications for e-learning practices in higher education institutions during the COVID-19 pandemic and offers recommendations for future research. This study provides evidences of students' readiness for e-learning in respect to their gender, age, ethnicity, level of education and field of study. This information could help lecturers to reflect on their own teaching practices, adjust their teaching approaches and subsequently, develop appropriate e-learning methods that best suit the student ersity in their classrooms.

Abstract: The study aims to investigate Person Ability and Item Fit instruments for critical thinking skills of the environment (Eco Critical Thinking Skill) in elementary pre-service teachers. Instrument investigations were carried out by describing item fit, separation of item and person, unidimensionality, and reliability of item and person. The research method was carried out quantitatively by collecting data through an open-answer essay test and an ecocritical thinking skill test. Participants in this study were Elementary School Teacher Education (ESTE) students from 3 universities in Surabaya of East Java, Surakarta of Central Java, and Manggarai of East Nusa Tenggara. The number of participants was 110 ESTE students. Data were analyzed with the Rasch Model WINSTEP software. The result of the study is that 36% of ESTE students have high Person Ability, 58% of them have average Person Ability, and the rest (6%) have low Person Ability. Students who have higher abilities are dominated by students from c us in Surabaya at 50%. Item fit Instrument with Mean Square (MnSq) 0.7 - 1.33. ZSTD -1.4 - 2.0 and Pt-measure Corr 0.49–0.6. The research concludes that an instrument of ecocritical thinking skills is a good fit instrument. The distribution of pre-service teacher qualifications from Surakarta and Manggarai is at a medium level, and students from Surabaya-East Java dominate high ability. Elementary pre-service teachers have the most dominant ability to explain and analyze a phenomenon or fact related to environmental damage.
