Learning-by-teaching is a generative learning strategy in which students are asked to teach what they are learning to others (Fiorella & Mayer, 2015). In this study, college students watched a multimedia lesson on chemical synaptic transmission with instructions that afterward they would explain the materials by making a lecture video…

In this study, we aim to investigate the types of questions that Taiwanese mathematics teachers pose and in which instructional situations they do so during mathematics lessons at the secondary school level. The classroom teaching of six experienced mathematics teachers was analyzed. Quantitative analysis showed that the mathematics teachers tend…

Linear functions are an essential part of school and university education. Nevertheless, this topic is challenging for many students--especially in STEM topics. In this article, we contribute to the understanding of learning difficulties in the context of mathematical and physical problems. Here, we present the results of an eye-tracking study on…

The purpose of the study was to examine the extent to which participants built meaningful culturally and linguistically responsive (CLR) relationships with students and to what extent those same participants engaged in cognitively demanding academic discourse with their students. The participatory action research (PAR) study took place in a rural…

Reading is one of the most important skills that students learn in elementary school. The problem addressed in this study is the decrease in proficiency of reading comprehension when primary grade students are assessed using a digital device to read and respond to instead of reading a text from a paper-based test. The purpose of this study is to…

Teaching practices that are aligned with how students learn improve educational outcomes for all students. Empirical evidence gained over recent decades has provided important new insights about the learning process common to students across learning contexts. These processes explain why some teaching practices are more effective than others. In…

Traditional rote learning methods often fail to adequately develop reasoning skills in mathematics, particularly among pre-university students. This study addresses challenges in fostering mathematical reasoning abilities, as evidenced by declining TIMSS results and resistance to pedagogical innovations. My online teaching with GeoGebra (MyOT_G+)…

This study was conducted to optimize the designs of learning guides embedded in a computer-based simulation environment. The research was based on the Cognitive Theory of Multimedia Learning and Cognitive Load Theory. We investigated computer simulations under four conditions that combined representation and imagination learning strategies. This…

In this opinion piece, we explore the idea that GenAI has the potential to fundamentally disrupt computer science education (CSE) by drawing insights from 10 pedagogical and cognitive theories and models. We highlight how GenAI improves CSE by making educational practices more effective and requires less effort and time, and all at a lower cost,…

This study examined the quality and types of mathematical tasks used for classroom instruction in an upper secondary school -- gymnasium. All the mathematical tasks presented in nine different school classrooms during the first semester of the school year 2018/2019 were analysed against a 5D analytical framework. The dimensions of the individual…

Cognitive complexity (CC)--the ability to differentiate and integrate in a dynamic environment--has been shown to be essential to understanding complex and uncertain environments. However, educational leaders' CC has not been examined. In the current exploratory research, we examine the effect of school middle leaders' CC in relation to their Big…

Instructional design deals with the optimization of learning processes. To achieve this, three aspects need to be considered: (1) the learning task itself, (2) the design of the learning material, and (3) the activation of the learner's cognitive processes during learning. Based on Cognitive Load Theory, learners also need to deal with the task…

The purpose of this study was to explore the influence of curricular organization on student cognitive load and student performance in online learning environments. The findings of this study contribute to the development of usable instruction design principles for online education. This research study used the lens of cognitive load theory to…

In this eye-tracking experiment, we compared instructional videos with static signals, dynamic signals and no signaling in a within-subject design. We tracked eye movements from 28 undergraduate chemistry students while they were watching instructional videos about reaction mechanisms in the different signaling conditions. Further, we assessed…

Three-dimensional (3D) digital anatomical models show potential to demonstrate complex anatomical relationships; however, the literature is inconsistent as to whether they are effective in improving the anatomy performance, particularly for students with low spatial visualization ability (Vz). This study investigated the educational effectiveness…
