The return on research investment resulting from new breakthrough scientific discoveries may be decreasing over time due to the law of diminishing returns, the relative decrease of research funding in terms of purchasing power parity, and various activities gaming the system. By altering the grant-review process, the scientific community may…

Personalized learning technologies such as automated reading tutors have been proposed as a way to help struggling readers acquire needed skills while simultaneously encouraging engaged, sustained reading of entire books. This article investigates a key step in the development of such technologies: translating an entire novel into a sequence of…

Pedagogical content knowledge (PCK) is a category of teachers' knowledge that encompasses knowledge used by teachers to successfully deliver subject materials to students in classroom practice. To examine the extent to which teachers have developed their PCK and how they could improve, they need a tool to measure such a concept. This study,…

Maintaining academic integrity is an area of major importance for today's institutions of higher learning. Despite universities having in place academic integrity policies and procedures, findings from semi-structured interviews with 26 academics from four, public Western Australian universities suggest that responses to incidences of student…

Investigated internal consistency reliability and criterion validity of the Asperger Syndrome Diagnostic Scale (ASDS) in a well-characterized sample of 120 children ([X-bar][subscript age] = 9.91; autism [AUT] n = 54; non-autism [NOT] n = 66) who completed comprehensive outpatient evaluations with a gold-standard measure, the Autism Diagnostic…

In this study, researchers compared the concordance of teacher-level effectiveness ratings derived via six common generalized value-added model (VAM) approaches including a (1) student growth percentile (SGP) model, (2) value-added linear regression model (VALRM), (3) value-added hierarchical linear model (VAHLM), (4) simple difference (gain)…

The Fundamentals in Meteorology Inventory (FMI) concept inventory exam was recently developed to gauge understanding of fundamental meteorological concepts among introductory meteorology students. The exam was iteratively tested and refined over several years using a small sample of students. With a goal of evaluating the reliability and validity…

This study explored the impact of mild bilateral or unilateral hearing loss on auditory, social, and behavior skills in early school-aged children. Thirty-two children (aged 5-9 years) were evaluated with parent and teacher questionnaires. Most outcomes were within the range of expected scores. However, functional auditory skills were below…

The aim of this study is to develop and apply a rubric to evaluate the solutions proposed for questions about electromagnetic induction belonging to university second year pre-service teachers. In this study which has pretest-posttest quasi-experimental design with control group, teaching of the topic of electromagnetic induction was applied to…

In this research, a new test for understanding simple fractions has been developed for students at the beginning of lower secondary education. In many countries, mathematics education in Grade 5 builds on elementary students' developing concepts of fractions. Understanding fractions causes many difficulties for students, and research on mental…

Purpose: Aphasia fluency is multiply determined by underlying impairments in lexical retrieval, grammatical formulation, and speech production. This poses challenges for establishing a reliable and feasible tool to measure fluency in the clinic. We examine the reliability and validity of perceptual ratings and clinical perspectives on the utility…

School climate measures are important tools that assist educators in evaluating the "norms, values, and expectations that support people feeling socially, emotionally and physically safe" (National School Climate Council, 2007, p. 4). Positive school climate is associated with academic performance indicators such as grade point average,…

The growing interest of educational researchers in computational thinking (CT) has led to an expanding literature on assessments of CT skills and attitudes. However, few studies have examined whether CT attitudes influence CT skills. The present study examines the relationship between CT attitudes and CT skills for preservice teachers (PSTs). The…

The current paper aims at developing and validating a Teacher Leadership Inventory (TLI). Adopting the theoretical-empirical strategy of instrument development, the procedure consisted of taking a sample of panel experts and undertaking six sequential empirical studies with sufficient samples of teacher leaders from China. After verifying content…

Two of the central issues in comparative judgement (CJ), which are perhaps underexplored compared to questions of the method's reliability and technical quality, are "what processes do judges use to make their decisions" and "what features do they focus on when making their decisions?" This article discusses both, in the…
