Instructional design (ID) models have been developed to promote understandings of ID reality and guide ID performance. As the number and diversity of ID practices grows, implicit doubts regarding the reliability, validity, and usefulness of ID models suggest the need for methodological guidance that would help to generate ID models that are…

This study aimed to investigate the item "Response Time Fidelity scores" ("RTFs"), "KuderRichardson Reliability" ("KR[subscript 20]") and "Cronbach's Alpha Reliability" ("alpha") coefficients, calculate "KR[subscript 20]" coefficients with "RTFs" for 30 threshold…

The adoption of Information and Communication Technology in Tanzanian higher education institutions has led to the implementation of different but equivalent Academic Information Systems to support the management of different activities of students. However, these systems are not well used to support decision-making in those institutions. This…

Student evaluations of teaching (SET) have been the principal instrument to elicit students' opinions in higher education institutions. Many decisions, including high-stake ones, are made based on SET scores reported by students. In this respect, reliability of SET scores is of considerable importance. This paper has an argument that there are…

Researchers analyzed data from elementary teachers (N = 233) to further establish the psychometric soundness of the Teacher My Class Inventory-Short Form. Supporting previous psychometric research, confirmatory factor analyses findings supported the factorial validity of the hypothesized five-factor solution. Internal reliability estimates were…

We present types of constructs, individual- and cluster-level, and their confirmatory factor analytic validation models when data are from individuals nested within clusters. When a construct is theoretically individual level, spurious construct-irrelevant dependency in the data may appear to signal cluster-level dependency; in such cases,…

Background: Nodular thyroid disease is relatively common although thyroid cancer is rare. The aim of this study is to evaluate the advantage and reliability of conventional ultrasound in correlating sonographic characteristics of thyroid nodule with US-FNAC guided result as a diagnostic aid in thyroid nodule. Method: 111 patients were examined by…

This paper highlights some of the vocabulary tests available, and reports the reliability of the modified Vocabulary Knowledge Scale (VKS) (Rosszell, 2007). Although there is no consensus as to what actually constitutes vocabulary knowledge, the notion that it is made up of receptive knowledge (words recognised or known when seen or heard) and…

Psychological testing can serve as a prototype on which to base a data-generated approach to instructional design. In "testing batteries" tests are used to predict achievement. In the proposed approach batteries of prescriptions would be used to produce achievement. In creating "test batteries" tests are selected for their…

In this study, evaluative case study was used to determine the realization level of the outcomes in the 10th chemistry curriculum. The 23 outcomes in the 10th grade chemistry curriculum were analyzed by two researchers. In order to determine the realization of the achievements based on practice, a chemistry teacher who attended the 10th grade…

Digital game-based assessments generate student process data that is much more difficult to analyze than traditional assessments. The formative nature of game-based assessments permits students, through applying and practicing the targeted knowledge and skills during gameplay, to gain experiences, receive immediate feedback, and as a result,…

This study develops two scales, namely, the outside school social media behavior (OSSMB) scale and inside school social media behavior (ISSMB) scale, to measure the types of behavior that adolescent students engage in on social media in two separate contexts: outside school and inside school. Data collected from 814 students in four Hong Kong…

Obsessive-compulsive disorder (OCD) in adolescents is understudied in Italy. This study evaluated the Italian Obsessive Compulsive Inventory--Child Version (OCI-CV) and its predictive validity on OCD symptoms at 1-year-follow-up, an aspect that was not investigated by previous international research. Use of OCI-CV in schools might enhance early…

Purpose: This research aimed to determine school happiness level of the teachers based on their opinions. For this purpose, 'School Happiness Scale' was developed by the researchers. The validity and reliability of the School Happiness Scale were tested. And then, the scale was applied to 484 teachers to determine their school happiness level.…

This research pioneered the investigation of the role of doctoral students' thinking styles in their program satisfaction and perceived intellectual competence. Participants were 285 STEM (science, technology, engineering, mathematics) students in Hong Kong. Results showed that students' thinking styles as measured by the Thinking Styles…
