Full-text available
In the last years, educators and policymakers have put a great deal of emphasis on the need to develop an education for the twenty-first century— an education that prepares our students to meet the economic, technological, and societal needs of our knowledge-based economies. There is wide agreement that the main characteristic of life and work in t...
Chapter
The chapter describes the framework theory approach to conceptual change and explains how it is applied to the development of rational number knowledge. Unlike existing approaches that emphasize continuities between natural and rational number, the framework theory approach to conceptual change focuses more on discontinuities. We argue that underst...
Article
Full-text available
We investigated the hypothesis that theory of mind (ToM) and epistemological understanding promote the aspect of science learning that concerns the ability to understand that there can be more than one representation of the same phenomenon in the physical world. Sixty-three students ranging in age from 10 to 12 years were administered two false-bel...
Article
Background Students are more effective when they employ appropriate strategies to regulate their learning processes and outcomes. However, many teachers do not provide, or provide very little, explicit instructions to promote this self‐regulated learning (SRL). This suggests that teachers’ belief systems may include beliefs that may be inconsistent...
Article
Full-text available
Rapid and radical changes in science, technology and society may result in new scientific concepts and new workplace practices, which require fundamental restructuring of prior knowledge. Over the years a noteworthy body of research has documented the processes of conceptual change, the learning mechanisms involved, and the instructional methods an...

Article
Pre-service teachers’ belief systems regarding the self-regulation of learning were investigated from a conceptual change perspective. Four hundred and twenty nine pre-service teachers answered a 6-point Likert scale Beliefs about Learning and Teaching (BALT) questionnaire. The results confirmed that beliefs theoretically consistent with SRL were b...
Article
Full-text available
Children construct intuitive understandings of the physical world based on their everyday experiences. These intuitive understandings are organized in skeletal conceptual structures known as framework theories. Framework theories are different from currently accepted science and impose constraints on how students understand the scientific explanati...
Article
Full-text available
Contemporary theories of learning and instruction emphasise the importance of students knowing how to effectively regulate their learning. A large body of research indicates that effective regulation of learning is beneficial for achievement. Set against this research are findings showing that the promotion by teachers of strategies for the self-re...
Article
Research has shown that differences in the prior knowledge of the participants and in the learning indexes adopted can explain why some studies show positive learning effects of analogy enriched text while others do not. In the present studies, these two factors were combined into one through the construction of a learning index that measured incre...
Article
Full-text available
We discuss the theoretical rationale and behavioral evidence for the involvement of Executive Function (EF) skills in the construction and employment of scientific and mathematical concepts that require conceptual changes for their formation. It is argued that conceptual changes such as knowledge revision and the formation of new and counter-intuit...
Article
Full-text available
Prior research has investigated the recruitment of inhibition in the use of science/mathematics concepts in tasks that require the rejection of a conflicting, nonscientific initial concept. The present research examines if inhibition is the only EF skill recruited in such tasks and investigates whether shifting is also involved. It also investigate...
Article
Full-text available
In this paper we focus on the development of rational number knowledge and present three research programs that illustrate the possibility of bridging research between the fields of cognitive developmental psychology and mathematics education. The first is a research program theoretically grounded in the framework theory approach to conceptual chan...
Article
The present research tested the hypothesis that the reading of science text can create new misconceptions in students with incongruent prior knowledge, and that these new misconceptions will be similar to the fragmented and synthetic conceptions obtained in prior developmental research. Ninety-nine third- and fifth-grade children read and recalled...
Article
We present two studies that investigated the adoption of visual/spatial and analytic strategies by individuals at different levels of expertise in the area of organic chemistry, using the Visual Analytic Chemistry Task (VACT). The VACT allows the direct detection of analytic strategy use without drawing inferences about underlying mental processes....
Conference Paper
Full-text available
In this research we investigated the adoption of visual and analytic strategies by individuals of different level of expertise when solving problems concerning the conception of organic compounds structural formulas. Furthermore, we investigated individuals" ability to use analytic strategies in cases where the inhibition of intuitive response stro...
Article
In two experiments we investigated the hypotheses that a) the refutation of more than one alternative conception, and b) the inclusion of categorical information in a refutation text will facilitate elementary school children's understanding of the scientific concept of the Earth. The results of the first experiment showed no clear support of the f...
Article
Full-text available
We argue that there is an increasing reliance on analytic strategies compared to visuo-spatial strategies, which is related to geometry expertise and not on individual differences in cognitive style. A Visual/Analytic Strategy Test (VAST) was developed to investigate the use of visuo-spatial and analytic strategies in geometry in 30 mathematics tea...

Based on the developmental transitions proposed by Stafylidou and Vosniadou (2004), three training sessions were created using the Cognitive Tutor Authoring Tools. The purpose was to compare the effects of two external representations on fraction understanding and interpretation, compared to a control group that received no training. The participan...
Article
It is argued that it is fruitful to examine cognitive development from a domain-specific, conceptual change (CC) point of view, but that both domain-specific and domain-general approaches are necessary in order to understand how cognitive development happens. The article starts with a description of the framework theory approach to CC and an explan...
Chapter
I was born in Athens, Greece, shortly after the end of the 2nd world war. My parents were the children of immigrant Greeks from Asia Minor who moved to Greece after the 1920–1922 Greek – Turkish War, which resulted in a massive population exchange.
Article
We describe the main principles of the framework theory approach to conceptual change and briefly report on the results of a text comprehension study that investigated some of the hypotheses that derive from it. We claim that children construct a naive physics which is based on observation in the context of lay culture and which forms a relatively...

The purpose of the present research was to create a categorization task to assess the conceptual changes that take place in children and adults with development and the learning of science. In specific, the categorization task aimed at investigating the accuracy and speed with which children and adults categorize concepts in naïve categories and re...
Article
We argue that learning science requires children to move from perceptually based representations to more abstract conceptual representations and to understand that appearance may sometimes deceive us and that the same phenomenon in the world can have more than one representation when seen from different perspectives. We also argue that the beginnin...

Full-text available
Three experiments used multiple methods—open-ended assessments, multiple-choice questionnaires, and interviews—to investigate the hypothesis that the development of students' understanding of the concept of real variable in algebra may be influenced in fundamental ways by their initial concept of number, which seems to be organized around the notio...
Chapter
Full-text available
We argue that science concepts are difficult to learn because they are embedded in different explanatory frameworks from those currently accepted by science. Students mechanically employ the usual enrichment mechanisms to add scientific information to existing but incompatible knowledge structures, destroying their coherence and creating internal i...

In order to understand the advanced, scientific concepts of the various disciplines, students cannot rely on the simple memorization of facts. They must learn how to restructure their naive, intuitive theories based on everyday experience and lay culture. In other words, they must undergo profound conceptual change. This type of conceptual change c...
