Measurement of CPS skills has emerged as an essential aspect in educational assessment. Modern research in CPS relies on theory-driven measurements that are usually carried out…

Star Math (SM) is a popular computer adaptive test (CAT) schools use to screen students for academic risk. Despite its popularity, few independent investigations of its diagnostic accuracy have been conducted. We evaluated the diagnostic accuracy of SM based upon vendor provided cut-scores (25th and 40th percentiles nationally) in predicting…

Daily living skills may affect repetitive behavior patterns in individuals with autism spectrum disorder (ASD).

This dissertation aimed to advance the field of biology education in several ways. First, we aimed to demonstrate if, and to what extent, student-generated conceptual models can be used on summative assessments to accurately assess student understanding of gene expression. Next, we described patterns of changes students make to conceptual models…

The role of children's receptive vocabulary knowledge in word and nonword reading (decoding) in an orthographically transparent language is debated. Moreover, we have little understanding of how the role of vocabulary might differ between monolingual children and bilingual children from immigrant families (or language minority bilingual children…

Second language (L2) writing research has demonstrated that young learners discuss linguistic issues, make use of feedback, and show a generally positive disposition toward writing tasks. However, many issues deserve further investigation. Regarding task implementation, few studies have been conducted with young learners writing individually, and…

Method: Participants were 82 students enrolled in a Chinese bilingual program in Western Canada. Students were recruited from Grades…

Writing comprehensibly, dynamically, and persuasively in a foreign language is a significant challenge for learners. Written communication assesses language and writing progress for various summative and developmental goals. Scenario-based assessment (SBA), as one of the methodologies of classroom-based assessment (CBA), aims to elicit both…

This study explored a way to help Japanese university students write longer essays while maintaining grammatical accuracy. Participants were three groups of students enrolled in a one-year EFL course in different academic years (N = 111), and the number of words they wrote in 30 minutes and the number of errors made per 100 words were compared. To…
