When students learn skills to solve problems by teaching others, they often need to receive scaffolding to benefit from learning by teaching. To facilitate learning by teaching (aka tutor learning), two types of scaffolding have been commonly studied--the scaffolding on how to teach (to induce appropriate teaching activities) and the one on how to…

In this paper, we investigate an interesting question that came up when reading a problem in a school textbook: What happens to the variance of a dataset in the case of changing one single data point, and why? Some of the answers are not surprising but here we find the full answer and demonstrate the understanding of it suitable for school…

Background/purpose: This study investigates how the teaching intervention and familiarity with the search topic enhance Greek students' behaviour while solving information problems. Materials/methods: Seven university students solved three information problems on the same search topic during an academic semester. After the first and before the…

Computer-based assessment (CBA) is a top-rated tool for conducting assessments, mapping learning outcomes, and selecting new candidates. Research that examines the development and use of CBA is also increasing from year to year, so without bibliometric analysis, it would be quite challenging to keep up with all of these studies. This study aims to…

Making drawings can help students avoid and overcome difficulties they encounter when solving real-world (or modeling) problems. However, many students do not make drawings spontaneously. In the present study, 132 students in Grades 9 and 10 were randomly assigned to the experimental conditions "with situational or mathematical drawing…

This is the protocol for a Campbell systematic review. The objectives are as follows: The purpose of this review is to synthesize the evidence about the efficacy of problem solving before instruction (PS-I) to promote learning and motivation in students. Specifically, this review is designed to answer the following questions: To what degree does…

PS-I learning approaches with an initial problem-solving phase (PS) followed by an instruction phase (I) can be optimised by providing adaptive (individualised) instruction that builds on students' problem-solving products. A computer-based implementation of both phases offers the possibility of adaptivity at the transition from the…

The development of geocapabilities has been a concern in geographical education, and the application of geospatial technologies such as geographical information systems (GIS) has been popularized in both geography and non-geography courses. However, there are still gaps in how GIS courses could be designed to promote students' geocapabilities. In…

Background: Problem-solving followed by instruction (PS-I) is a powerful design shown to transform students' conceptual understanding and transfer. Within PS-I, no research has examined how moment-by-moment determinants of affective states impact the problem-solving phase and posttest performance. Methods: I develop a multimodal learning analytics…

Written instructions seldom need to be read when playing videogames. Instead, gaming often involves early information foraging and expansive exploration behaviors. We use data from the Programme for International Student Assessment (PISA) to explore whether students who regularly play videogames (daily gamers) adopt behaviors that are typical of…

Unemployment among science graduates in Rwanda remains a pressing challenge due to limited industrial opportunities and insufficient market demand for scientific skills. This study assesses chemistry teachers' entrepreneurial competencies for developing small chemical-based businesses. This study adopted an explanatory sequential design, combining…

When learning a new concept, should students engage in problem solving followed by instruction (PS-I) or instruction followed by problem solving (I-PS)? Noting that there is a passionate debate about the design of initial learning, we report evidence from a meta-analysis of 53 studies with 166 comparisons that compared PS-I with I-PS design. Our…

As a self described lesson collector, author Charles Lovett enjoys gathering "interesting" lessons and teasing them apart to find out what makes them "tick", particularly the pedagogy. He often wonders what decisions the teacher made that generated such an interesting and successful learning environment. Here he describes a…

In this paper, the authors introduce a research instrument (Draw a STEM Learning Environment: D-STEM) and its accompanying rubric (the D-STEM Rubric), both of which were developed based upon relevant research studies. The authors describe their usefulness to school principals in commencing conversations with their school's STEM [Science,…

The main objective of this article is to analyse informal learning processes in the field of video games. As many teenagers are engaged in these kinds of practices, the big question is: How do teens learn to play video games? In most cases they do not learn to play video games at school or with their parents, and therefore it is necessary to map…
