The purpose of these notes is to provide examples of large-scale geometry problems that have the potential to promote "constructive struggling" in high-school geometry classrooms. These problems are suitable for being explored in a dynamic geometry environment. The notes also contain brief sketches of solutions to the two problems.

Purpose: This research aims to investigate and define the eight wastes of lean philosophy in higher education institutions (HEIs) by proposing a multi-stage model. Design/methodology/approach: The authors have used a specific multi-criteria decision-making method, fuzzy decision-making trial and evaluation laboratory, to investigate the…

This study designs and implements interdisciplinary STEM instruction by adopting modelling-based physics programming, and explores its effectiveness on learning. A quasi-experimental study was conducted. The experimental group wrote programs to solve physics problems by following the modelling process, while the control group solved general…

Anecdotal evidence of successful cannabis treatment in autism spectrum disorder (ASD) are accumulating but clinical studies are lacking. This retrospective study assessed tolerability and efficacy of cannabidiol-rich cannabis, in 60 children with ASD and severe behavioral problems (age = 11.8 ± 3.5, range 5.0-17.5; 77% low functioning; 83% boys).…

This study investigated the performance of 790 fourth graders from Taiwan for judging the reasonableness of a computational result by using corresponding methods pertaining to whole numbers. A number-sense web-based two-tier diagnostic test was used to assess the number-sense performance of the fourth graders who participated in this study. The…

This research aimed at examining the effectiveness of collaboration of Jigsaw and problem-based learning (PBL) model in developing students' critical thinking skills. This research exerted an experimental design using pre-experimental one group pretest-posttest. The implementation of such model collaboration was carried out in SMK Batik 1…

BACKGROUND: School-based extracurricular activity participation is one of the primary avenues for prosocial activity engagement during adolescence. In this study, we test the "overscheduling hypothesis" or whether the negative relationship between structured activity intensity (ie, hours) and adolescent bullying and fighting levels off…

Background: Motor vehicle crashes are the leading cause of adolescent death. Cell phone use while driving is a contributor to adolescent motor vehicle crash risk. Objective and directly observable measures of cell phone use while driving are needed to implement interventions aimed at reducing cell phone-related crash risk. Aims: To describe novel…

The Good Behavior Game (GBG) is a popular group contingency implemented to decrease disruptive behavior in classrooms. However, despite numerous replications of the GBG, there are few direct comparisons evaluating the effectiveness of specific components of the GBG. In the present study, we directly compared the type of feedback delivered during…

This study aimed to adapt the Physical Metacognition Inventory (PMI) developed by Taasoobshirazi and Farley (2013) to Turkish. PMI consists of 24 items and six factors. The scale items were translated into Turkish by the researchers, and a Turkish-English comprehensibility form was prepared to elicit the opinions of Turkish-English language…

Children in most schools, especially in Primary 7 (age 11, England Year 6), are increasingly engaging with technology and social media in a way that is completely different from 10 or even 5 years ago. More time is spent on phones and devices and, as a result of this, observations and appreciation of the wonderful natural world around them are…

Examples are an indispensable part of mathematical thinking through analogy, learning and the teaching process. In this study, the strategies that high school students used in example generation activities in mathematics course; operational and conceptual knowledge levels were determined and their effect on example generation ability was examined.…

Analogical reasoning is assumed to play a large role in learning and problem solving in everyday and school settings. It was examined whether a newly developed dynamic test of analogical reasoning would be sufficiently difficult for identifying young gifted children's potential for solving analogies. The study included 74 gifted (n = 31) and…

Analogies between old and new concepts are common during classroom instruction. Previous transfer studies focused on how features of initial learning guide later, spontaneous transfer to new problem solving. We argue for a shift in the focus of analogical-transfer research toward understanding how to best support analogical transfer from previous…

Collaborative problem-solving (CPS) as a key competency required in the 21st century. There has been an increasing need to understand CPS since it involves not only cognitive but also social processes, and thus its process is difficult to examine. Recent research has highlighted that computer-based learning environments provide an opportunity for…
