The Autism Impact Measure (AIM) was designed to track incremental change in frequency and impact of core ASD symptoms. The current study examined the structural and convergent validity of the AIM in a large sample of children with ASD. The results of a series of exploratory and confirmatory factor analyses yielded a final model with five…

According to (inter)national policy and curriculum documents, the acquisition of research skills is an important objective of secondary education. However, the conceptualization and hence the operationalization of this concept seems ambiguous. Furthermore, no test exists to assess students' proficiency in (a broad range of) research skills in a…

This preliminary study was conducted to examine and verify the validity and reliability of the instrument on the Malaysian Academician Happiness Index (MAHI) on resilience. MAHI could be seen as a tool to measure the level of happiness and stress of academicians before determining how resilient the academicians were. Resilience can be defined as a…

There are numerous tools available to assess coping strategies used by children and adolescents. Many of the existing measures are widely used within diverse settings, often outside of the populations within which the measures were developed. Given the varying use of coping strategies among different populations, there is a need to ascertain the…

Some of the most important skills of university students is to develop the capacity to resolve problems posed by their communities, which implies that students become independent, autonomous and self-regulated. Also they need to be capable of monitor, asses and modify their learning through their own process of metacognition, this way they can…

This study determined the psychometric properties of the Economics Achievement Test (EAT) using Item Response Theory (IRT). Two popular IRT models namely, one-parameter logistics (1PL) and two-parameter logistics (2PL) models were utilized. The researcher adopted instrumentation research design. Four research questions and two hypotheses were…

The aim of the study was to adjust the measurement model of an instrument of sources of Self-efficacy for Mathematics to sample of university students from Northeast of Mexico and the sex measurement invariance. A second-order modeling was performed, which shows convergent and discriminant validity, which corresponds to the original Bandura theory…

The Teacher Efficacy for Inclusive Practice (TEIP) scale is an instrument created by Sharma et al. to assess efficacy of instruction in inclusive settings. Despite its increase in use, the TEIP has not been validated with a Spanish teacher population. The aim of this study was to: (1) analyze the psychometric properties and factor structure of the…

This article outlines the development and validation of the Computer-Delivered Test (CDT) Acceptance Questionnaire (CTAQ). The CTAQ was designed to be a practical measure of CDT acceptance of Singapore secondary and high school students (Grades 7-12) toward taking tests within an e-assessment system. The stages of test (questionnaire item)…

This article aimed to establish the psychometric properties of the Chinese version of the Subjective Happiness Scale (SHS-C) and to investigate the convergence between SHS-C and multidimensional subjective well-being (MSWB). A total of 543 college students completed the following measures: the SHS-C, the MSWB scale, Rosenberg's self-esteem scale,…

The Boxall Profile provides a framework for the structured observation of children in nurture groups. It is a detailed and rigorously trialled normative diagnostic instrument developed for teachers and teaching assistants to measure children's levels of emotional and behavioural functioning. Moreover, it highlights specific targets for…

Programs utilizing research-tested evaluation tools can help identify effective educational strategies and document program effectiveness and impact. Using the case of the UF/IFAS Extension Family Nutrition Program (FNP), this article illustrates steps for conducting a rigorous assessment of the measurement properties of evaluation instruments.…

Cognitive diagnosis models (CDMs) estimate student ability profiles using latent attributes. Model fit to the data needs to be ascertained in order to determine whether inferences from CDMs are valid. This study investigated the usefulness of some popular model fit statistics to detect CDM fit including relative fit indices (AIC, BIC, and CAIC),…

Cognitive diagnostic models (CDMs) have received sustained attention in educational settings because they can be used to operationalize formative assessment to provide diagnostic feedback and inform instruction. A large number of CDMs have been developed over the past few years. An important component of all CDMs is a Q-matrix that specifies a…

An inquiry approach to learning can have a positive impact on students' attitudes to science and their science literacy skills; two attributes that have been in steady decline internationally. The professional development of teachers in inquiry science is one way to ensure that teachers are equipped with effective strategies to teach science,…
