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…

Context: Competency-based education requires strong planning and a vehicle to deliver and track students' progress across their undergraduate programs. Clinical presentations (CPs) are proposed as 1 method to deliver a competency-based curriculum in a Canadian undergraduate athletic therapy program. Objective: Validation of 253 CPs. Setting:…

School-based practitioners are often called upon to provide assessment and recommendations for struggling students. These assessments often open doors to specialised services or interventions and provide opportunities for students to build competencies in areas of need. However, these assessments often fail to highlight the abilities of these…

This study explores fourth year college students' content retrieval from reading textless versus verbal images. Furthermore, it examines the extent to which the respondents comprehend and understand them. The procedures include selecting an image from the internet, designing a written test with its rubrics and exposing it to jury members to…

The purpose of this study is to examine validity and reliability of the Albanian version of the Depression, Anxiety and Stress Scale (DASS), which is developed by Lovibond and Lovibond (1995). The sample of this study is consisted of 555 subjects who were living in Kosovo. The results of confirmatory factor analysis indicated 42 items loaded on…

The purpose of the present experiment was to replicate and extend the literature on using selection-based instruction to teach responses to interview questions by (a) evaluating the emergence of recombinative (i.e., combinations of taught) and novel (i.e., untaught) topography-based intraverbal responses, in addition to exact repetitions of taught…

In this paper we describe the development of a questionnaire designed to assess the probability content knowledge of prospective primary school teachers. Three components of mathematical knowledge for teaching and three different meanings of probability (classical, frequentist and subjective) are considered. The questionnaire content is based on…
