Teaching performance can be assessed validly only if the assessment involves an appropriate, authentic representation of real-life teaching practices. Different skills interact in coordinating teachers' actions in different classroom situations. Based on the evidence-centered design model, we developed a technology-based assessment framework that…

In the age of the internet, it is increasingly difficult to write homework assignments in a way that encourages students to struggle with a problem on their own without seeking answers from other sources. This is especially true in lower-level courses, where students often start with the attitude of "I can't do this." In this article, I…

In this study, it was aimed to examine the relation between seventh-grade students' quadrilaterals achievement levels and Van Hiele geometric thinking levels. Survey method was used. The sample of the study was 160 students from the three different districts of Kayseri, as Melikgazi, Incesu, and Tomarza. Van Hiele geometric thinking test and…

In this exploratory case study, the researchers conducted a qualitative analysis of six teaching sessions to describe the use of gestures and diagrams by a teacher and her students with learning disabilities when engaging in secondary level algebra (e.g., Algebra I & II content). The teacher and her students used gestures, such as pointing and…

Continually increasing demands are being placed on the educational system to prepare students with technical skills due to the exponential implementation of information, technology and automation in the workforce. Students should work with design, problemsolving and computational methods and tools early on in their school lives in basic education…

The development of expertise in chemical information literacy requires practicing these skills in the context of chemistry work. The integration of information literacy in problem-based learning is an instructional strategy that can be used to situate skill development in the chemistry classroom. This work describes a mixed-methods approach to…

Including opportunities for students to experience uncertainty in solving mathematical tasks can prompt learners to resolve the uncertainty, leading to mathematical understanding. In this article, we examine how preservice secondary mathematics teachers' thinking about a trigonometric relationship was impacted by a series of tasks that prompted…

We focus on human capital measured by skills and analyse its relationship with R&D investments and productivity across 12 OECD economies and 17 industries. We compute a measure of sectoral human capital defined as the average cognitive skills of the workforce in each country-sector combination. The variation in labour productivity that can be…

Over the past 20 years, a significant amount of research has located sports coaching principally as an educational endeavour. In particular, non-linear educative approaches have attracted much attention yet few studies have explored in any real depth the theoretical underpinnings of such practices. Where conceptual analyses have been conducted,…
