Two approaches to causal inference in the presence of non-random assignment are presented: The Propensity Score approach which pseudo-randomizes by balancing groups on observed propensity to be in treatment, and the Endogenous Treatment Effects approach which utilizes systems of equations to explicitly model selection into treatment. The three…

Recent research suggests using multiple screening measures to identify students at risk for academic difficulties may decrease the number of students incorrectly identified as such. Gated frameworks in which students that score below a cut-score on an initial measure are assessed with a follow-up measure have been recommended. Researchers have…

Clinical cognitive ability assessment--and its corollary, score interpretation--are in a state of disarray. Many current instruments are designed to provide a bevy of scores to appeal to a variety of school psychologists. These scores are not all grounded in the attribute's theory or developed from sound measurement or psychometric theory. Thus,…

This inquiry is focused on three indicators of the precision of measurement--conditional on fixed values of ?, the latent variable of item response theory (IRT). The indicators that are compared are (1) The traditional, conditional standard errors, s(eX|?) = CSEM; (2) the IRT-based conditional standard errors, s[subscript irt](eX|?)=C[subscript…

One of the important theories in education and psychology is Generalizability (G) Theory and various properties distinguish it from the other measurement theories. To better understand methodological trends of G theory, a thematic content analysis was conducted. This study analyzes the studies using generalizability theory in the field of…

Massive Open Online Courses (MOOCs) have become more and more popular recently. These courses have attracted a large number of students world-wide. In a popular course, there may be thousands of students. Such a large number of students in one course makes it infeasible for the instructors to grade all the submissions. Peer assessment is thus an…

Clinician numeracy (CN), the ability to use and understand quantitative data in patient care, is an important skill for healthcare professionals. Nonetheless, it is recognized that many healthcare professionals, including doctors, have deficiencies in CN, and that this may affect patient safety. In our previous research using the Medical…

The substantial growth of online learning, and in particular, through massively open online courses (MOOCs), supports research into nontraditional learning contexts. Learners' confusion is one of the identified aspects which impact the overall learning process, and ultimately, course attrition. Confusion for a learner is an individual state of…

Student growth percentiles (SGPs) are currently used by several states and school districts to provide information about individual students as well as to evaluate teachers, schools, and school districts. For SGPs to be defensible for these purposes, they should be reliable. In this study, we examine the amount of systematic and random error in…

This article describes and evaluates a web-based coaching program designed to support teachers in implementing Common Core-aligned math instruction. Web-based coaching programs can be operated at relatively lower costs, are scalable, and make it more feasible to pair teachers with coaches who have expertise in their content area and grade level.…

Students in secondary school often struggle with symbol sense, that is, the general ability to deal with symbols and to recognize the structure of algebraic formulas. Fostering symbol sense is an educational challenge. In graphing formulas by hand, defined as graphing using recognition and reasoning without technology, many aspects of symbol sense…

21st-century learning is integral to the transformation of the curriculum in Malaysia with the transition from School Integrated Curriculum (SIC) to School Standard Curriculum (SSC) introduced around 2014. During this time, the implementation of 21st-century learning was acceptable and very rewarding. However, the impact of implementation on…

Equipping new teachers in today's society is a noble and challenging task. Of late, many additional licensing standards for teachers create additional responsibilities for universities that provide pedagogy, knowledge, and content for teacher candidates. Identification of best practices that support teacher candidates on the Educative Teacher…

Objective: The aim of this study was to analyse the views of different members of the school community regarding the health and well-being of young people and health promotion in schools. Design: Case study design was used, in which the Personal Wellbeing Index--School Children's Questionnaire was administered to young people, and focus groups…

COVID-19 has upset the traditional ways of teaching and looks set to continue to have an impact in the coming years. The situation in Taiwan--partial disruption and then an early return to classes--allows for a comparison of student performance in a conventional teaching and testing environment with the non-contact teaching/testing environment…
