The learners' conceptual understanding has become one of the leading research areas conducted by educational researchers. Both students and current educators should actively work to improve their understanding of alternative conceptions and deepen their conceptual knowledge. One of the essential concepts in chemistry learning is colligative…

The paper reports on a case study addressing the question of how young children think about the living/non-living distinction before and after their engagement in a 'Philosophy for Children'-inspired learning environment. The aim of the learning environment was to help children come up with a better identification of living and non-living things…

This study investigates the influence of inquiry-based laboratory activities on the understanding of heat concepts and the self-efficacy beliefs of pre-service primary teachers. Recognizing that both scientific literacy and teaching efficacy are critical for effective science education, this research aims to determine how inquiry-based laboratory…

Teaching music often focuses on developing musical concepts, through comparisons and discriminations. This paper contributes to the discussion on concept development in music through recognition of common elements in a situation and a shift from a local to a general level, considering theoretical approaches to mathematical generalisation. It sets…

The study investigates secondary students' understanding of "orbital" and "electron cloud" concepts in different quantum contexts (for values of the ?principal quantum number n = 1 and n = 2) on the basis of their verbal and pictorial representations, evaluating also their consistency. Participants, which were 192 12th-grade…

Reading mathematical texts is closely related to the effort of the reader to understand its content; therefore, it is reasonable to consider such reading as a problem-solving activity. In this paper, the Principle of Mathematical Induction was given to secondary education students, and their effort to comprehend the text was examined in order to…

Background: It is stated that it is necessary that students develop their nanoliteracy in order to come up with everyday issues arising from Nanoscale Science and Technology (NST) applications, taking informed decisions and estimating the potential risks and benefits. Even though the inclusion of NST in compulsory education is supported by many…

The study aims to investigate students' conceptualisation of the quantum numbers concept through their verbal descriptions and pictorial representations of the corresponding atomic structures. The study was conducted with the participation of 192 12th-grade students from six secondary schools in Northern Greece, via a paper-and-pencil test,…

The present study investigated the association of students' fundamental ideas and misconceptions about ontological features of atom identity and behavior with the formation of their portrayed representations of the atomic structure. Participants (n = 421) were secondary education students in the eighth, tenth, and twelfth grades. Students'…

The main purpose of this study was to investigate the consistency of pictorial representations of the atomic structure drawn by students on the basis of particular quantum numbers' characteristics. Participants were 192 students of the 12th grade of secondary Greek schools. This study's instrument, a paper-and-pencil assessment tool, included four…

The aim of the present study is to explore on the alternative conceptions of impetus theory and projectile motion of students with high functioning autism spectrum disorders and compare them with those of typical development. For this purpose, an experimental investigation was conducted with 19 students with high-functioning autism (age range:…

Children, like everyone, have been affected in multiple ways by the changes the pandemic has caused. This study aims to explore how 4-6-year-olds (N = 50) express through drawings and narrations their meanings and feelings around coronavirus. From a rights-based approach and in particular, children's rights to access information, to express their…

The aim of the paper is to analyse and discuss the results of research concerning the development of historical concepts by Greek primary education pupils when engaged in a history game based on ICT. For purposes of the research, an experimental intervention was implemented. It was addressed to 67 pupils aged 10-11 years old, using an application…

Science is one of the most important subjects for students at all educational levels. To promote engagement, hands-on experiments can provide a 'realistic and exciting experience of the content' (Holstermann, Grube and Bögeholz, 2010: 744) and hopefully facilitate motivation. In this article, George Stylos and Konstantinos T. Kotsis present four…

The introduction of the computer into the educational process is a fact. The educational use of new technologies creates a new, more appealing and enjoyable learning environment. The introduction of new technologies into school differentiates the role of the professor by giving him/her a guiding character in a process of experiential approach to…
