We present a case study of proving by three 12-13-year-old students with different levels of mathematical giftedness. After analysing students' proofs, we conclude that: there was a relation on the consistency and the students' levels of mathematically giftedness, being the least consistent the student not mathematically gifted and the most…

Anonymous questionnaires are frequently used in research with adolescents in order to obtain sincere answers about sensitive topics. Most longitudinal studies include self-generated identification codes (SGICs) to match information. Typical elements include a combination of letters and digits from personal data. However, these data may make the…

In this research, we have explored the possible differences in students' performance in grade nine chemistry exams that could have been influenced by a different instructional approach in grade eight. We compared two groups of students: one group had received a transmissive propaedeutic approach in grade eight (especially related to the memorising…

Despite the research exploring the benefits of using cooperative learning in secondary physical education, several research gaps still remain, namely, limited research on its effects on prosocial behaviours, the impact on adolescents as they grow up, and the lack of assessment of differently structured cooperative learning frameworks. The goal of…

We present the validation of a questionnaire for compulsory secondary school students (seventh to tenth grade), designated "Educational learning environments for ESO pupils" (CEApA_ESO), for the purpose of evaluating learning environments. Although many instruments have been developed in this area, our work attempts to comprehensively…

Socio-scientific issues demonstrate the relationship between science, technology, and society by considering currently unresolved questions. The problem of plastics and their pollution is just one example with important implications for the planet. The aim of this paper is to revisit socio-scientific issues and see them as a way of developing…

Creative educational methodologies capable of engaging students in interactive, enjoyable learning help to lessen students' anxieties and motivate them. In this context and with the objective of making easier the learning of the chemical symbols and periodic table as well as introducing the concept of chemical formula, we have designed the…

In this study reciprocal peer tutoring was implemented in middle school mathematics classes for a six-month period. The effects of this methodology on students' mathematics achievements, mathematics anxiety levels, attitudes towards mathematics, and mathematics self-concepts were examined. Study participants included 768 students in grades 7-9…

This book presents the first results from the third cycle of the IEA International Computer and Information Literacy Study (ICILS 2023). This study investigated how young people are prepared for life in a world where the capacity to use computers and digital information responsibly, safely, and effectively is essential. The study reports on data…

Education is seen as a resource at a global level but is currently considered to be in crisis in many parts of the world. This constitutes a significant drawback in terms of humanity's prosperity and well-being since education is the key not only to an educated workforce but also to humane, collaborative, and caring societies. Even within this dim…

The academic effects of learning statistics and probability through peer tutoring were analysed in the research reported on here. Two hundred and eight students enrolled in Grades 7, 8 and 9 participated. Fixed- and same-age peer tutoring was implemented 3 times per week for 6 weeks. Each tutoring session lasted approximately 25 minutes. The main…

This study reports the academic benefits of peer tutoring in algebra for middle school students. A total of 380 students enrolled in grades 7th and 8th participated in the study. Two peer tutoring sessions took place during each week (10 weeks). Interactions between peers lasted 20 to 25 minutes for each session. The typology of tutoring was fixed…

This study provides evidence on the impact of including warm messages in elaborated feedback. These messages are aimed at the motivational process that can be mobilised by feedback and that which can condition its reception and the way students face the task (post-feedback behaviour). In a task where secondary school students had to learn a new…

This study investigates whether potential differences in the weight of out-of-school and in-school learning environments affect the acquisition of L2 English by teenagers in two geographical contexts, more and less English-rich, and with less and more linguistic distance to English, respectively. Participants were two groups of 14-15-year-olds,…

Background: A number of studies have contemplated aspects of cooperative learning that might emerge from a unit of sport education [Dyson, B., L. L. Griffin, and P. Hastie. 2004. "Sport Education, Tactical Games, and Cooperative Learning: Theoretical and Pedagogical Considerations." "Quest" 56 (2): 226-240; Dyson, B. P., N. R.…
