Investigating students' conceptual change about colour in an innovative research-based teaching sequence

Abstract

This paper is the second part of a multiphase study investigating the impact of a mathematical model, the Addition Table of Colours (ATC), in the learning of colour phenomena. The ATC instruction was undertaken in several 8th grade classes in three different Portuguese schools (250 students) and included collaborative activities through Lab stations model. In the control group (204 students), the colour phenomena were taught in the traditional way, with the goals set by the teachers, without any intervention of the project. The two groups of students were compared in terms of content knowledge acquired in the learning of this subject through comparison and analysis of their pre and post-tests. Quantitative analyses of the pre/post-tests revealed five variants of students’ representations about this phenomenon. We found that the ATC model, inserted in an interactive and carefully designed teaching environment, is more effective in promoting conceptual change and scientific understandings of colour phenomena.

Determination of Science Teacher Candidates' Knowledge and Skill Levels About Co

“…There are researches implicate that the students have misconceptions on colur and vision or colored shadows. (Mota, & dos Santos, 2018;Naranjo Correa et al, 2016;Martinez-Borreguero, et al, 2013). The main idea was to create a learning environment that makes students familiar with the experience of observing "differently coloured objects" illuminated by differently coloured light (Haagen-Schützenhöfer, 2017).…”

Social Sciences’ Transformation in Light of Covid-19

“…Transformation can be characterized as (Ahrens, Zaščerinska, Lange, & Aļeksejeva, 2021) a system process as its properties are linked, -a complex process as its elements are interwined, -a linear process as it proceeds from one stage/phase to another, -a cyclic process as it can be repeated, -of social nature as it changes within and by society and/or community, -of bi-module nature as it includes both external and internal perspectives (Zascerinska, 2013). Social sciences' transformation are identified to be (Mota & Lopes dos Santos, 2018) as shown in Figure 1 ontological, and epistomological. Based on Vygotsky's theories (Vygostky, 1934(Vygostky, /1962), these two processes are considered to be inter-connected.…”
