A theoretical analysis of the validity of the Van Hiele levels of reasoning in graph theory [PDF]

Journal on Mathematics Education, 2022
The need to develop consistent theoretical frameworks for the teaching and learning of discrete mathematics, specifically of graph theory, has attracted the attention of the researchers in mathematics education. Responding to this demand, the scope of the Van Hiele model has been extended to the field of graphs through a proposal of four levels of ...

Proof levels of graph theory students under the lens of the Van Hiele model [PDF]

International Journal of Mathematical Education in Science and Technology, 2022
This work is devoted to exploring proof abilities in graph theory of undergraduate students of the Degree in Computer Engineering and Technology of the University of Seville. To do this, we have designed a questionnaire consisting of five open-ended items that serve as instrument to collect data concerning their proof skills when dealing with graphs ...

Functionally annotated electrophysiological neuromarkers of healthy ageing and memory function. [PDF]

Hum Brain Mapp
We analysed a large open resting‐state EEG dataset and found that dynamic rather than static neuromarkers better capture cognitive ageing. We clarified that individualised alpha power reflects memory performance rather than ageing. Finally, we used functionally annotated source reconstruction to reveal domain‐specific electrophysiological mechanisms ...

Teacher and students response to learning devices based on van hiele theory [PDF]

Journal of Physics: Conference Series, 2020
AbstractCritical thinking is one of the higher order thinking ability that needs to be developed in the 21st century. In fact, that the students’ critical thinking ability are still low. In learning geometry students are still dependent on the teacher in receiving information, the media are inadequate in learning geometry so that students have not been

Re‐evaluation of erythritol (E 968) as a food additive

EFSA Journal, Volume 21, Issue 12, December 2023., 2023
Abstract This opinion addresses the re‐evaluation of erythritol (E 968) as food additive and an application for its exemption from the laxative warning label requirement as established under Regulation (EU) No 1169/2011. Erythritol is a polyol obtained by fermentation with Moniliella pollinis BC or Moniliella megachiliensis KW3‐6, followed by ...

Simplest Shapes First! But Let's Use Cognitive Science to Reconceive and Specify What “Simple” Means

Mind, Brain, and Education, Volume 17, Issue 1, Page 5-19, February 2023., 2023
Abstract Children's informal and formal learning experiences with geometric shapes currently result in misconceptions that persist into adulthood. Here, we combine research from mathematics education as well as cognitive science pertaining to concepts, categories, and learning strategies to propose a more optimal progression that is better specified ...
