Liu, Chunhong; Zhang, Jieyu; Zhang, Haoyang; Li, Xiaoniu; Zhang, En – International Journal of Information and Communication Technology Education, 2023
Using the educational knowledge graph to express the logical characteristics of knowledge, this paper takes project-driven learning in the teaching of "Information Technology in Secondary Schools" as an example and studies the group cooperative teaching mode based on the educational knowledge graph. The relationship between knowledge…

Braund, Martin – Canadian Journal of Science, Mathematics and Technology Education, 2021
The COVID-19 pandemic has resulted in unprecedented amounts of information communicated to the public relating to STEM. The pandemic can be seen as a 'wicked problem' defined by high complexity, uncertainty and contested social values requiring a transdisciplinary approach formulating social policy. This article argues that a 'Critical STEM…

Noss, Richard; Bakker, Arthur; Hoyles, Celia; Kent, Phillip – Educational Studies in Mathematics, 2007
We investigate the use and knowledge of graphs in the context of a large industrial factory. We are particularly interested in the question of "transparency", a question that has been extensively considered in the general literature on tool use and, more recently, by Michael Roth and his colleagues in the context of scientific work. Roth uses the…

Brown, Norman R.; Siegler, Robert S. – Psychological Review, 1993
A metrics and mapping framework is proposed to account for how heuristics, domain-specific reasoning, and intuitive statistical induction processes are integrated to generate estimates. Results of 4 experiments involving 188 undergraduates illustrate framework usefulness and suggest when people use heuristics and when they emphasize…

Takaci, D.; Pesic, D.; Tatar, J. – International Journal of Mathematical Education in Science and Technology, 2006
In this paper, results of a questionnaire about continuity of functions are analysed. The tested students attend Novi Sad grammar school. The aim of this test was to check the student's theoretical and visual knowledge of continuous functions at the end of their high school education. The questions were given with and without the graphs of…
