Multivariate analysis of variance (MANOVA) is a statistical method used to examine group differences on multiple outcomes. This article reports results of a review of MANOVA in gifted education journals between 2011 and 2017 (N = 56). Findings suggest a number of conceptual and procedural misunderstandings about the nature of MANOVA and its…

Using survey responses from public school teachers and principals in Alaska, this article describes their understanding of tenure statute, and how that understanding affected support, perceived effectiveness, and valuation of tenure. Teachers and principals who inflated tenure protections were more likely to support it; the more teachers inflated…

Teachers' pedagogical content knowledge (PCK) importantly contributes to instructional quality and student outcomes. We aimed to complement the limited insights into preservice preschool teachers' PCK, and its association with opportunities to learn (OTL), during teacher training. We offered 162 first-to-final-year preservice preschool teachers…

The field of geography is important for any sustainability education. The aim of geography education is to enable students to understand the environment, its influence on human activity, and how humans influence the environment. In this article we present a study on how the interplay between the three pillars of sustainability thinking…

This study focuses on proportional division, a specific problem type of proportions and proportional relationships, which embeds a part-part-whole relationship. We investigated how students in grades 6 to 9 solved and perceived three proportional division problems. Analysis of the students' performance on the tasks revealed three types of…

The current research aims at constructing a developmentally sensitive mindreading scale (i.e., a battery of tasks measuring different aspects of mindreading ability in children from 1 to 3.5 years of age). Over 300 Polish children were tested at six-month intervals with 48 different tasks designed to measure mindreading ability (for a total of six…

Student learning in simple electric circuits has been extensively studied, which has revealed a large number of persistent misunderstandings. This study applies the conceptual framework model to investigate student difficulties in the knowledge integration perspective. The results are used to guide the design of a concept test that targets the…

Like all SSI, the COVID-19 pandemic requires decisions that are contentious, involve scientific thinking, and vary across social groups.
