The Transtheoretical Model (TTM) conceptualizes change as a process with five identifiable stages. Each stage has psychological characteristics that are manifestations of an underlying continuum of change. Surprisingly few studies have applied the TTM to understand the process involved with academic development. The objective of this study was to…

In this study a survey was developed to investigate students' engagement during general chemistry laboratory sessions. Aspects of engagement surveyed included cognitive, behavioral, and emotional engagement, and the survey items were focused on activities during the pre-laboratory introduction, laboratory procedures, and data collection.…

We revisit the merits of the retrospective pretest-posttest (RPP) design for repeated-measures research. The underutilized RPP method asks respondents to rate survey items twice during the same posttest measurement occasion from two specific frames of reference: "now" and "then." Individuals first report their current attitudes…

Students with emotional and behavioral disorders (EBD) have difficulty forming and maintaining high-quality relationships with their teachers, yet they have the most to gain from positive relationships. The majority of studies examining teacher-student relationships have been correlational, focused on preschool and elementary-aged children, and…

This manuscript presents the results from a study to investigate the technical characteristics of two versions of a number line assessment (NLA 0-20 and NLA 0-100). The sample consisted of 60 kindergarten and 46 first grade students. Both number line versions had sufficient alternate form and test-retest reliability. The NLA 0-20 had low and the…

This article considers how a handicapping system should be devised for squash. It looks at the American scoring system, and whether it is possible to have a fair system of handicapping. We consider "fair" from a perspective of expected number of rallies won and probability of winning.

The Wechsler Intelligence Scale for Children-Fifth Edition (WISC-V; Wechsler 2014a) "Technical and Interpretation Manual" (Wechsler 2014b) dedicated only a single page to discussing the 10-subtest WISC-V primary battery across the entire 6 to 16 age range. Users are left to extrapolate the structure of the 10-subtest battery from the…

Background: There is paucity in availability of valid and reliable measures of psychopathology that can be routinely applied with an intellectual disability (ID) population in clinical practice. The psychometric properties of the Clinical Outcome Routine Evaluation-Learning Disabilities 30-Item version (CORE-LD30) are examined. Method: The…

In this ITEMS module, we provide a two-part introduction to the topic of reliability from the perspective of "classical test theory" (CTT). In the first part, which is directed primarily at beginning learners, we review and build on the content presented in the original didactic ITEMS article by Traub and Rowley (1991). Specifically, we…

Computational thinking (CT) has been recognized as an essential part of every child's education (Wing, 2006) and Bebras contest items have been frequently used to measure CT. Think alouds has emerged as a prominent method for identifying thought processes and correcting problems with assessments. As little research has examined validity evidence…

Reliability is a measure of consistency. It is the degree to which student results are the same when they take the same test on different occasions, when different scorers score the same item or task, and when different but equivalent tests are taken at the same time or at different times. Reliability is about making sure that different test forms…

One of the questions with the longest history in educational assessment is whether it is possible to increase the reliability of a test simply by altering the way in which scores on individual test items are combined to make the overall test score. Most usually, the score available on each item is communicated to the candidate within a question…

This research reports learning strategies of the first-year Estonian university students in mathematics. The data were collected during two years from 440 university students of different disciplines. The respondents were among students who take at least one compulsory mathematics course during their first study year. The participants filled out a…

Social validity focuses on a program's goals, procedures, and outcome, which helps determine if an intervention is socially acceptable and valued. This study represents a conceptual replication of the investigation by Lane and colleagues (2009) regarding the psychometric properties of the Primary Intervention Rating Scale (PIRS), a teacher survey…

Metamemory can be defined as the knowledge about one's memory capabilities and about strategies that can aid memory. In this paper, we describe the development and validation of the Eyewitness Metamemory Scale (EMS), tailored specifically for use in face memory and eyewitness identification settings. Participants (N = 800) completed the EMS and…
