Using Balacheff's (2013) model of conceptions, we inferred potential conceptions in three examples presented in the spanning sets section of an interactive linear algebra textbook. An analysis of student responses to two similar reading questions revealed additional strategies that students used to decide whether a vector was in the spanning set…

This paper presents the experimental work developed to measure the learning process through concept map analysis. The development of a concept map is requested by the students for each chapter or theme of the subject. As a result, maps from engineering courses have been analyzed. The measurements carried out consider several parameters, such as…

Purpose: Our objective was to test the labeling effect in autistic children. The effect has been robustly tested in typically developing (TD) individuals. TD children expect that any two objects that receive the same linguistic label will have similar properties, which suggests that they generate concepts based on acts of labeling. The labeling…

Sustainability action at universities is complex and requires engaging multiple competences that reside on different levels outside and inside the organisation. In addition to individual competences, social communities also possess collective resources and characteristics that do not translate into a sum of individual abilities. Based on a…

In this paper, a self-created analogy is presented based on comparing the process of osmosis with a situation recreated in a train carriage. It was implemented with upper-secondary education students at a secondary school in Chiclana de la Frontera (Cádiz, Spain). To assess the progression of the students' models on osmosis, their activities…

Purpose: The purpose of this research is to analyse the level of knowledge about the Sustainable Development Goals (SDGs) of pre-service teachers in Early Childhood and Primary School Education at the University of Valencia (Spain) and the origin of this knowledge over several academic years, as well as to compare it with that of students of the…

Identifying the mental models held by students has been widely emphasized as being a pivotal aspect of effective science education. In fact, it allows us to understand students' conceptions, detect teaching-learning difficulties and tailor instruction accordingly. Hence, in this study, the plant nutrition mental models held by upper secondary…

The purpose of this article is to conduct a mathematical and phenomenological comparison of three concepts: (1) the finite limit of a function at a point, (2) the finite limit of a sequence, and (3) the infinite limit of a sequence. Additionally, we aim to analyse the presence of these concepts in Spanish textbooks. The methodology employed is…

The internet has become a key environment for children's learning and leisure at an increasing early age. Yet, little is known about what children understand about the internet. We conducted semi-structured interviews with 111 children aged five to nine to assess their notions about the internet, the authorship of online content and the…

Although citizenship's literacy in biodiversity is a promising way of confronting its loss, the unawareness about this topic is generalised particularly regarding plants. The latter phenomenon, named Plant Blindness (PB), not only refers to the inability to notice and identify the surrounding plants, but also to the lack of knowledge about the…

Students with autism spectrum disorder frequently face challenges when learning mathematical concepts. For example, they may have difficulties solving mathematical word problems, in particular Cartesian product problems. This research is a case study with a multiple probe design in which the participants were three Spanish students diagnosed with…

Many studies have been conducted in recent years on the explanations given by preschool-age children about different natural phenomena. Nonetheless, very few studies have actually focused on the important domain of matter and its transformations. Specifically, the field of chemical reactions remains unexplored. This qualitative study aims to…

This study examines the development of the concept of the ecological niche among 10-11-year-old students and their ability to use this concept to give their opinions on the socially relevant and controversial possibility that wolf populations might be established in the mountains surrounding the school. A total of 21 elementary school students…

The integrated STEAM approach arises when a contextualized problem's resolution requires different contributions (views) from each discipline. In this descriptive article we discuss the views needed from chemistry, technology, design skills, mathematical modelling and the artistic support necessary for constructing a scientific model that explains…

In this study, we analyzed the descriptive knowledge and mental models of the phenomenon of tides manifested by 111 preservice primary teachers. The instrument employed is an open-ended questionnaire, analyzed by means of an approach that explores the descriptions, explanations, and predictions in respect of this phenomenon by our subjects. First,…
