Psychometric measurement models are only valid if measurement invariance holds between test takers of different groups. Global model tests, such as the well-established likelihood ratio (LR) test, are sensitive to violations of measurement invariance, such as differential item functioning and differential step functioning. However, these…

Teaching simple circuits and Ohm's law to students in the introductory classroom has been extensively investigated through the common practice of using incandescent light bulbs to help students develop a conceptual foundation before moving on to quantitative analysis. However, the bulb filaments' resistance has a large temperature dependence,…

There is a wealth of evidence that people's reasoning is influenced by explanatory considerations. Little is known, however, about the exact form this influence takes, for instance about whether the influence is unsystematic or because of people's following some rule. Three experiments investigate the descriptive adequacy of a precise proposal to…

Background: Many state agencies have developed model wellness policies (MWPs) to serve as examples for schools when writing their own school wellness policy (SWP). The purpose of this study was to evaluate if a MWP aids schools in writing stronger, more comprehensive SWPs. Methods: For this cross-sectional study, 91 school districts submitted…

Research generally supports the use of error-correction procedures that require active student responses (ASRs). However, some recent research suggests that requiring ASRs after errors is not always advantageous for individuals with autism spectrum disorder (ASD). We examined acquisition in a receptive identification task for two learners with ASD…

We investigate the main question of whether higher education institutions are able to increase their performance due to mergers, takeovers, or organizational restructuring. The problem of measuring performance when there are several "output" and "input" indicators can currently be solved by recourse to a proven data analysis…

Background: This study describes an approach for the use of a specific type of qualitative evidence synthesis in the matrix approach, a mixed studies reviewing method. The matrix approach compares quantitative and qualitative data on the review level by juxtaposing concrete recommendations from the qualitative evidence synthesis against…

This paper addresses the growing problem of retractions in the scientific literature of publications that contain bad data (i.e., fabricated, falsified, or containing error), also called "false science." While the problem is particularly acute in the biomedical literature because of the life-threatening implications when treatment…

This article proposes a study design developed to disentangle the objective characteristics of a learning situation from individuals' subjective perceptions of that situation. The term objective characteristics refers to the agreement across students, whereas subjective perceptions refers to inter-individual heterogeneity. We describe a novel…

In this research, we examined the responsiveness to treatment in 49 Italian children with Dyslexia. In part A, we compare the efficacy of a phonological-based treatment (Ph-T) with a cognitive training of executive functions (CT). In part B, we investigate whether a sequential treatment (CT+Ph-T) has a larger remedial effect compared to the pure…

The primary goal of this project is to assess the students' better communication attainment after applying a series of five interactive strategies to an experiment group of subjects. This class will be compared with a control group of other participants, and in their class, the interactive approaches are not emphasized and practiced openly. The…

In this paper we report on a survey study of teachers' perceptions of how mathematics textbooks, including broadly student books, teacher manuals, and exercise books, facilitate or hinder teachers' teaching in Shanghai educational settings. For the study we established a conceptual framework about teachers' teaching, partly drawing on Shulman's…

Since Hong Kong returned to Chinese sovereignty, national identity building became an important part of school education meeting some resistance in Hong Kong society. In 2012, thousands of school stakeholders protested against the introduction of the 2012 Guide of Moral and National Education (MNE). These conflicts have influenced teachers'…

The current research addresses interesting and still mostly neglected question of how introductory philosophical disciplines (such as "Introduction to philosophy", "Introduction to ethics" etc.) affects students' comprehension of the concept of critical thinking which is one of the most important descriptive and normative…

Purpose: The purpose of this study was to further evaluate an eight-step partner instructional model developed by Kent-Walsh and McNaughton that has been demonstrated to improve implementation quality and fidelity among adults in clinical and educational settings who support the use of augmentative and alternative communication (AAC) for…
