While decades of research have deepened our understanding of time perception, the perception of (manipulated) video speed has been relatively underexplored but is gaining interest with recent technological advances. This study systematically investigated human perception of "video speed," "clip duration" and "original…

Infants who receive better counting input at home tend to become toddlers with better number knowledge in preschool. However, for many children, in-person counting experience is not always available, despite educational media becoming increasingly prevalent. Might virtual counting experience benefit the young mind? Using a novel online looking…

This study investigated the effect of video lecture types on the performance of students in computational problem-solving practices. A total of 19 university students participated in the computational problem-solving practices that mostly required declarative knowledge, and 22 university students participated in the computational problem-solving…

Based on the purpose of improving the communication power of the computational intelligence short videos of China Communist Youth League, this paper takes six typical computational intelligence short video IDs and their popular computational intelligence short videos of the Communist Youth League at the provincial level as the research object…

Background: South African teachers' mathematical knowledge for teaching and number sense are markedly low, evidenced in national and international research. There is a call for supporting teachers in developing their knowledge and confidence in teaching mathematics. Aim: The aim of this article is to share how pre-service teachers (PSTs) used the…

Since the phenomenal success of deep neural networks (DNNs) on image classification, the research community have been developing wider and deeper networks with complex components for a variety of visual understanding tasks. While such "heavy" models achieve excellent performance, they pose two main challenges: (1) the training requires a…

In this paper we study how children aged 12-15 years learn together with their parents while solving a series of playful inquiry-based tasks with an educational robot. The purpose of the study is to understand how children and their parents learn mathematics and computational thinking in non-formal out-of-school learning activities. For the study…

In this article, the authors share frameworks for problem types and students' reasoning about integers. The authors found that all ways of reasoning (WoRs) were used across grade levels and that specific problem types tended to evoke particular WoRs. Specifically, students were more likely to use analogy-based reasoning on all-negatives problems…

Live streaming platforms like Twitch.tv count millions of viewers and performers, pointing to novel practices and interactions. Instructional applications of this phenomenon are rising with thematic channels and shows aimed at teaching and debating a variety of subjects ranging from art to programming. However, few research publications have…

The background of this article is an interest in analysing how assessment of professional skills is conducted in higher education contexts, drawing on video data from a course on maritime navigation. The empirical study focuses on a) how students working in a bridge simulator are able to display their knowledge about how to calculate the relation…

Purpose: Most educational assessments tend to be constructed in a close-ended format, which is easier to score consistently and more affordable. However, recent work has leveraged computation text methods from the information sciences to make open-ended measurement more effective and reliable for older students. This study asks whether such text…

With COVID-19 continuing to make meeting face-to-face impossible, the Canadian Mathematics Education Study Group/Groupe Canadien d'Étude en Didactique des Mathématiques (CMESG/GCEDM) executive decided that, for the first time, the CMESG/GCEDM meeting would be held virtually. By necessity, the program had to be much compressed with no topic…
