This paper describes the conceptions about complex numbers that a group of university students has, these were built from the application of an activity sequence centered on these numbers. This sequence is based on the APOS theory, some aspects of semiotic representation theory, and the use of digital technology. Particularly, both the general…

Primary physical education is quickly becoming an area of academic interest with a particular focus on new entrants into the profession. This study adopts a Personal Construct methodology to identify how pre-service teachers in England construct their knowledge of primary physical education. Our findings present four themes for knowledge…

Environmental knowledge and awareness of individuals affect their attitudes and behavior toward the environment. In this regard, it is essential to specify how environmental issues are interpreted in individuals' cognitive structures. This study aims to investigate preservice science teachers' cognitive structures on environmental issues. The…

Light is used ubiquitously across science and engineering to explore, characterise, understand matter, and catalyse processes. Relative to its utility in science and engineering, very little research has been conducted on how students develop an understanding of light-matter interactions, especially at the quantum level, which is necessary to…

Photosynthesis is the most important biochemical process on Earth. Most living beings depend on it directly or indirectly. Knowledge about photosynthesis enables us to understand how the world functions as an ecosystem and how photosynthesis acts as a bridge between the non-living and living worlds. It is, therefore, understandable that…

The development of rich, reliable, and robust measures of the composition, structure, and stability of student thinking about core scientific ideas (such as natural selection) remains a complex challenge facing science educators. In their recent article (Nehm & Schonfeld 2008), the authors explored the strengths, weaknesses, and insights provided…

Cognitive performance can be improved through the explicit instruction of strategies that produce good performance. Variations in the ability to access knowledge relevant to specific materials that might affect strategy use, students' perceptions of strategies, and strategy maintenance are considered. (TJH)

The aim of this study was three-fold: (1) to determine 6th, 8th and 10th grade students' environmental knowledge and attitudes in Turkey; (2) to investigate the effect of the grade level and gender on students' environmental knowledge and attitudes; (3) to explore how environmentally responsible behaviour is related to environmental knowledge,…

Assessed the impact of elementary science experiences on the development of sixth-graders' epistemological views. Found that, compared to students in a traditional science classroom, those in a constructivist classroom developed an epistemological stance toward science that focused on the central role of ideas in the knowledge acquisition process.…

Provides an overview of the research concerning students' perceptions of foreign nations. Compares and contrasts the various measurement techniques including the two most commonly used; semantic differential scales and pair comparisons. Suggests methods for alternative analysis and offers recommendations for future research. Includes a sample…

Discusses Vee mapping, a technique to assist students in categorizing the relationship between the conceptual and procedural aspects of science. Presents a study to investigate elementary education majors' (n=27) use of the Vee heuristic and concept mapping for the construction of knowledge; attitudes toward learning science in collaborative…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
