Education administrators expect teachers to participate in professional learning. Traditional professional learning for teachers comes in workshops, professional learning communities, meetings, conferences, self-guided professional development, coaching, and courses (Bill & Melinda Gates Foundation, 2014). Teachers are dissatisfied with this…

In an increasingly online world, multimedia content for instructional use in chemistry is abundant. It can be difficult to discern a good resource from a poor one, even if the chemistry content in the video is accurate (which it may not be). Sound chemistry content alone does not guarantee that the videos were made with best principles in mind…

Research shows that the intensity of high school course-taking is related to postsecondary outcomes. However, there are various approaches to measuring the intensity of students' course-taking. This study presents new measures of coursework intensity that rely on differing levels of quantity and quality of coursework. We used these new indices to…

This study investigates the development of lexico-grammatical complexity in two levels of graded readers, beginner and intermediate. Using the linguistic features described in Biber et al. (2011), 58 graded readers were analyzed. Biber et al. (2011) proposed a lexico-grammatical developmental sequence based on empirical research. In this study, 11…

Several studies in multimedia learning have examined the effect of emotional design. Recent findings from cognitive psychology provide opportunities for educators to use more direct ways of manipulating emotion to enhance learning. These studies have shown that emotionally arousing words and pictures are remembered better than neutral ones.…

This article reports the results of an empirical investigation on teachers' beliefs about teaching and learning and the globalised world as a teaching subject. Following a qualitative reconstructive approach, the study investigated how teachers' beliefs and the way teachers address the complexity of sustainability issues relate to each other.…

The acquisition of quantifiers is a central topic in cognitive science. The present study investigated the emergence, frequency, and non-target-like production of the universal quantifiers "all," "every," and "each" in child English from a linguistic perspective, based on the data from longitudinal naturalistic…

Previous studies have shown that encouraging students to use self-explanation strategies has proven effective in text-focused learning contexts. However, no study to date has focused on how students' strategy preference moderates the effect of self-explanation strategies on learning from video lectures. The current study investigated how students'…

The present study explored the accuracy of participants' (N = 317) metacognitive awareness (self-reported difficulty and confidence) of psychology concepts and the moderating effects of their psychology background (academic major, number of psychology courses completed, and overall psychology course grades). Participants first rated the difficulty…

A one-degree angle would certainly be difficult to draw accurately, especially without the aid of other tools like a protractor. However, mentally making a one-degree angle in visualized imagination is not only possible, but it is important for students' emergent understandings of angular measure. When students begin learning about length,…

Although cognitive load theory research has studied factors associated with motivation, these literatures have primarily been developed in isolation from each other. In this contribution, we aimed to advance both fields by examining the effects of instructional strategies on learners' experience of cognitive load, motivation, engagement, and…

The present study analyzed the structural and the content complexity of 76 preservice science teachers' socioscientific argumentation in the context of a mandatory COVID-19 vaccination. Data were analyzed within the methodological frame of qualitative content analysis. Concerning the structural complexity, the participants' socioscientific…

The paper discusses an alternative method of assessing the difficulty of pupils' programming tasks to determine their age appropriateness. Building a program takes the form of its successive iterations. Thus, it is possible to monitor the number of times such a program was built by the solver. The variance of the number of program builds can be…

The study set out to explore different mathematical difficulties among 877 second-grade children and to test the effect of memorization versus conceptual practices with number combinations. It used a latent profile analysis of baseline measurements of digit writing speed, number combination fluency, multidigit calculation, and number sense skills…
