The current study explores the connection and affordances of talk and gesture in collaborative science problem-solving activities using an emerging analytical approach. A total of 15 three to five-member groups of middle school students participated in a set of clinical collaborative science problem-solving activities. Six groups (three low- and…

Early number skills represent critical milestones in children's cognitive development and are shaped over years of interacting with quantities and numerals in various contexts. Several connectionist computational models have attempted to emulate how certain number concepts may be learned, represented, and processed in the brain. However, these…

Background and Context: Debugging is a challenging yet understudied practice within recent collaborative K-12 physical computing contexts. We examined think-aloud interviews and reflections of seven high school student pairs who debugged researcher-designed buggy electronic textile projects. Objective: We asked: (1) What strategies did student…

Gestures--hand movements that accompany speech and express ideas--can help children learn how to solve problems, flexibly generalize learning to novel problem-solving contexts, and retain what they have learned. But does it matter who is doing the gesturing? We know that producing gesture leads to better comprehension of a message than watching…

This study investigated the impact of computer-aided assessment on the enhancement of critical thinking skills in non-routine problem-solving across three distinct learning delivery modalities: fully online, balanced blended, and predominantly face-to-face (F2F) blended. The study aimed to evaluate the effectiveness of computer-aided assessment in…

Background: A lack of student 'buy-in' and engagement are often major obstacles in academic literacy courses. To create a dialogic learning environment which encourages student investment and challenges traditional student-lecturer hierarchies of power, the curriculum of a first-year academic literacy course at a South African university was…
