This article focuses on the case study of the concept of covalent bonding for 10th grade pupils in France. On the basis of their conceptions and difficulties, didactical engineering has been established that should lead to an improvement in the understanding of this concept. After analyzing the pupils' difficulties, we reflected on the…

In this article, we describe the main phases in the development and validation of a questionnaire measuring secondary students' teleology and essentialism conceptions in the context of genetics. The validation process involved 714 Swiss and French secondary school students from 14 different schools. The process included interviews, several pilot…

This article reports the development of Chem'Sc@pe, an escape game activity for first- and second-year undergraduate students, covering various topics from an introductory organic chemistry course. The objective was to encourage them to review notions learned in class in a fun and collaborative environment. The set comprises a game board…

In this paper we describe the results of some experiments about using surprising physics demonstrations, presented as magical phenomena followed by scientific explanations, for introducing physics topics in several teaching contexts. All the demonstrations have been designed to be implemented with easy to get and cheap materials, so that students…

Environmental education is becoming a growing area of interest in early childhood education. In France, more time is given to environmental education activities in the preschool curriculum. Yet, there is a risk of narrowing preschool environmental education only to carry out pro-environmental behaviours, without giving pupils the opportunity to…

Background: This work is based on the idea that young children benefit from early introduction of scientific concepts. Few researches describe didactical strategies focusing on physics understanding for young children and analyse their effectiveness in standard classroom environments. Purpose: The aim is to identify whether didactical strategies…

Qualitative research conducted with 237 pupils from Canada, France, and Morocco, between 10 and 12 years of age, on the setting and functioning of simple electric circuits, demonstrates that similar explanatory systems of the students. For this, we had given them a paper and pencil questionnaire of a sixty minutes duration. The first question was…

The purpose of this study is to analyze the studies, which include Item Response Theory among the keywords, available in the Web of Science database between 1980-2018 through bibliometric analysis method. A total of 1,367 academic works has been analyzed. The authors, journals and countries having the highest number of studies in the field and…

Our work extends a previous study of epistemological presuppositions in teaching quantum physics in upper scientific secondary school in France. Here, the problematic reference of quantum theory's concepts is treated at the ontological level (the counterintuitive nature of quantum objects). We consider the approach of using narratives describing…

Teaching physiology can be challenging as students are initially required to understand basic and abstract concepts. Thus students typically view physiology as a "difficult" subject and place an emphasis on rote learning and memorization. Here, we attempted to address this knowledge gap by introducing a pedagogical intervention into the…

In many situations, the change in the conceptual understanding of students is measured using a single question. This is, for instance, the case in peer instruction where students answer twice to the same questions, before and after the discussion phase. Using item response theory and assuming that students proficiencies are normally distributed,…

In this article, we present two concrete applications of the concept of the human element to chemistry education; starting with a course and experimental project on blue pigment synthesis and concluding with cross-disciplinary lessons and experiments on blue photography. In addition to the description of the content of these courses, we explore…

The Billotron is a device designed and built by the LPC Caen to illustrate the methods with which physicists are able to study the basic structure of matter, in particular the nucleus of the atom.

Background: Many researchers have investigated student reasoning in Newtonian mechanics. In 1979 Viennot revealed that most students associate the concept of force with the velocity or acceleration of a motion. Forty years later, student understandings remain a major challenge for teachers. The implications of this challenge are still unclear,…

The paper is set in socio-material farming to offer a way of conceptualising actions and interactions of children in preschool involved in the understanding of scientific concepts. A model of early science education about the physical phenomena of shadow formation is implemented in group work in a French context. The research involved 44 children…
