Cognitively demanding tasks provide important opportunities for students to develop an understanding of mathematics; however, they are challenging to launch and implement. The authors designed a secondary methods unit on launching tasks. Participants in the study were enrolled in five different methods courses. Using a noticing framework, findings…

The purpose of this study was to determine if the MathTwitterBlogosphere (MTBoS), an online community of practice, provides opportunities for mathematics educators to learn about the knowledge and conceptions that support the effective use of cognitively demanding tasks, including mathematical knowledge for teaching, visions of high-quality…

This study investigated the effects of four subtitle modes on the listening comprehension of TED (Technology, Entertainment, Design) talks and academic vocabulary learning of intermediate (non-English major) and advanced (English major) English as foreign language (EFL) learners. A total of 272 Chinese college sophomore students were randomly…

Smartphone-based experimental exercises were incorporated as part of the homework problems in an introductory mechanics course at a university. A quasi-experimental field study with two cohorts design was performed to measure the impact of such exercises on motivation, interest and conceptual understanding. The empirical results on learning…

The purpose of this review paper was to conduct a literature review on the effects of colors on learners' learning cognition and emotions. Findings of this review could inform practitioners about better color choices they could use to present information and design learning materials in ways that decrease learners' cognitive load, increase their…

Background: The evaluation of informal arguments is a key component of comprehending scientific texts and scientific literacy. Aim: The present study examined the nomological network of university students' ability to evaluate informal arguments in scientific texts and the relevance of this ability for academic success. Sample: A sample of 225…

Nowadays, students are becoming familiar with the computer technology at a very early age. Moreover, the wide availability of the internet gives a new perspective to distance education making e-learning environments crucial to the future of education. Intelligent tutoring systems (ITSs) provide sophisticated tutoring systems using artificial…

The purpose of this study was to identify the feasibility of using the pupil dilation and heart rate variability (HRV), to diagnose learners' changing cognitive load in a video learning setting. The pupil dilation and HRV of 23 participants were recorded during their learning progress, and the learning materials, including differences in task…

When learning procedures in real life, learners generally use action atomization strategies (interleaving instructions consultation and execution) and need several repetitions to acquire the skill. However, in studies on procedural learning, delayed execution paradigms (2 separate steps consisting of instructions consultation, then execution)…

Worked examples and self-explanations studies have been conducted predominantly with college students in controlled laboratory settings. While there is evidence showing the independent effects of these learning strategies with college students, little is known about the combined effects with K-12 students in ecologically-valid environments.…

Providing test questions after an initial study phase is a common instructional technique. In theory, questions that require higher-level (deep) processing should be more beneficial than those that require lower-level (shallow) processing. However, empirical evidence on the matter is inconsistent. To shed light on two potential reasons for these…

Scaffolding techniques, such as sequencing and fading, used in online video lectures may help mitigate the negative relationship between complex contents represented by intrinsic load and content understanding represented by germane load. This study analyzed survey responses from university students (n = 2365) who participated in online classes in…

Recent developments in Virtual Reality (VR) technology has prompted the manufacturing industry and software vendors to investigate VR's potential for process enhancement. In this paper, we present a study to investigate whether using VR could reduce an individual's cognitive workload during the process of programming an industrial robot. The…

Assessment is a key lever for educational improvement. Assessments can be used to monitor, signal, and influence science teaching and learning -- provided that they are of high quality, reflect the rigor and intent of academic standards, and elicit meaningful student performances. Since the release of "A Framework for K-12 Science…

The article aims to determine the academic performance and errors in the resolution of types of problems of application of the quadratic function, of high school students from the Los Lagos Region and Los Rios Region in Chile. The approach is qualitative and descriptive with case studies. A math test with open response problems and an opinion…
