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…

The purpose of this study is to examine the characteristics of students' thinking about graphs while evaluating statements from Calculus. We conducted clinical interviews in which undergraduate students evaluated mathematical statements using graphs to explain their reasoning. We report our classification of students' thinking about aspects of…

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…

We perform dynamic investigation of two surprising geometrical properties, each of which involves additional properties. In the first task the property belongs to two regular polygons with the same number of sides and with one common vertex. It is found that all the straight lines that connect corresponding vertices of the two polygons intersect…

This research is motivated by the perspective that when empirical studies and assessment frameworks inform each other, assessments can enrich science education and strengthen its connections to modern science. The research proposes a bioenergy competency assessment for science education. It uses an argument-based approach to validation. Multiple…

An interesting Sangaku problem was chosen and a multidirectional study was performed, which included finding the locus of a circle's center moving while being tangent to two circles. It also included finding the radius of that circle given the datum that it is also tangent to the side of an isosceles triangle. Two different proofs are presented of…

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…

Purpose: The aims of this systematic review are to provide a critical overview of short-term memory (STM) and working memory (WM) treatments in stroke aphasia and to systematically evaluate the internal and external validity of STM/WM treatments. Method: A systematic search was conducted in February 2014 and then updated in December 2016 using 13…

The Every Student Succeeds Act (ESSA) aims to ensure that all students are college- and career-ready by requiring all schools to implement high-quality accountability systems and services for students. The ESSA impacts assessment practices in schools by requiring staff to account for a broader range of variables related to student well-being,…

The goal of this study is to determine the degree of leadership skills practiced by principals at UNRWA schools. In order to achieve this goal a questionnaire consisting of 56 items was developed, which included two domains: Administrative and Technical skills, and personal and social skills. This questionnaire had been verified in terms of its…

Assessment and evaluation tools and instruments are developed to measure many things from content knowledge to misconceptions to student affect. The standard validation processes for these are regularly conducted and provide strong evidence for the validity of the measurements that are made. As part of the suite of validation tools available to…

In educational contexts, questioning performs a number of functions. These include facilitating learning in the classroom and the recognition of achievement through examinations and other assessments. Good quality questions are important to ensuring that these functions are achieved. This research focused on educational exams and used views from…

The present study validated the Expectancy Value Scale (EVS) for teachers regarding information technology. Participants were 866 teachers from 58 kindergartens in China. Based on a randomly split sample, we used one half (n = 433) for exploratory factor analysis, and anther half (n = 433) for confirmatory factor analysis. Both EFA and CFA results…
