This study reports on the psychometric evaluation of the Chinese version of the Homework Management Scale (HMS). The HMS was designed to assess students' homework management strategies. Based on a randomized split of 884 high school students in China, we conducted exploratory factor analysis on Group 1 (n = 442) and confirmatory factor analysis on…

The standards for Master's Level Student Affairs Professional Preparation Programs, first published in 1986, were among the first standards published by the Council for the Advancement of Standards in Higher Education (CAS; Ebbers & Kruempel, 1992). With the latest revision in 2012, the CAS standards for preparation of student affairs…

Justification is a critical mathematical practice that must play a role in teaching and learning at all grade levels. Having students share their reasoning and explain how they know something is true or correct is the process of justification. The authors (a team of teachers and researchers) worked together for two years with an NSF-funded project…

The reliability and validity of course grades as measures of general education learning outcomes were assessed using the multitrait-multimethod (MTMM) proposed by Campbell and Fiske. Convergent validity and discriminant validity were assessed on college undergraduate students over a 12-year period. Two procedures were used to test the MTMM. The…

In this research, I set out to elucidate the relationships that might exist between students' conceptual understanding upon which they draw in their proof activity. I explore these relationships using data from individual interviews with three students from a junior-level Modern Algebra course. Each phase of analysis was iterative, consisting of…

The What Works Clearinghouse (WWC) Standards Briefs explain the rules the WWC uses to evaluate the quality of studies for practitioners, researchers, and policymakers. This brief explains what baseline equivalence is and why it matters. As part of the WWC review process for certain types of studies, reviewers assess whether the intervention group…

This paper describes the development and validation of a science teacher leadership instrument modeled on the seven domains of the Teacher Leader Model (TLM) Standards (The Teacher Leadership Exploratory Consortium, 2011). Instrument development was part of National Science Foundation--funded Mathematics and Science Partnership (MSP) program that…

We collected data from 691 teachers from 139 schools in Michigan to validate the instrument titled Data-informed Decision-making on High-impact Strategies, designed based on Marzano's (2003) 11 high-impact strategies. Results of confirmatory factor analysis strongly supported the 11-factor model as the most valid approach to measure teachers'…

Dynamic assessment (DA) research, still in its infancy, takes its roots from Vygotsky's concept of zone of proximal development (ZPD) to account for learner's developmental process. Breaking away from a static, incomplete and, thus, unethical assessment of learner's abilities, DA came to the fore to better crystallize learner's levels of abilities…

In this commentary on "Does Sorting Students Improve Scores? An Analysis of Class Composition" (Collins and Gan 2013), the author discusses the findings in Collins and Gan's study on grouping to provide appropriate-level instruction to promote students' academic growth. This commentary critiques the credibility and validity of the…

Guided by the theory of figured worlds, this qualitative study focuses on 18 faculty members employed at community colleges, broad access liberal arts, comprehensives, and regional research universities, who have constructed professionally and personally meaningful careers at institutions that differ from their original aspirations and/or their…

Many universities strive to become world-class and two of Singapore's universities are almost there, being ranked 12th and 13th in the QSWUR 2015/16. This study looked into the details of indicator rankings and found that the two universities are comparable to those in the top 10 universities in the same ranking in practically all indicators with…

There is always a chance that examinees will answer multiple choice (MC) items correctly by guessing. Design choices in some modern exams have created situations where guessing at random through the full exam--rather than only for a subset of items where the examinee does not know the answer--can be an effective strategy to pass the exam. This…

The purpose of this study was to provide initial validity evidence for measuring multidimensional subjective well-being in a Hispanic sample with the Interpersonal, Community, Occupational, Physical, Psychological, Economic (I COPPE) Scale. Participants were 641 English-speaking adults who self-identified as Hispanic. Bi-factor analyses were used…

Instruction promoting reasoning and proof should be a part of K-12 mathematics teaching. Preservice teachers (PSTs) need mathematics content instruction that helps them construct valid justifications for mathematical notions and develop positive perceptions of proof. This case study describes instruction with proof-related tasks and manipulatives…
