En la primera parte del artículo, se incide en la importancia del estudio de las emociones desde la didáctica de las ciencias, así como en la necesidad de establecer programas de intervención metacognitivos y metaemocionales, tanto en el aprendizaje como en la formación del profesorado, para que alumnos y profesores puedan conocer sus emociones, controlarlas y autorregularlas. En la segunda parte, nos centramos en las emociones en el conocimiento didáctico del contenido del profesorado de ciencias, incluyendo algunos resultados tanto del diagnóstico emocional del profesorado, según distintas variables, como del programa de intervención de la Universidad de Extremadura.

As we have seen as a consequence of the COVID-19 global pandemic, our scientific-technological society requires a transformation of knowledge in a global, digital and virtual manner. In light of this, and to improve the public health skills of professionals working to promote health education, one of the current priorities is to train pre-service teachers on how to search for health-related scientific knowledge relating to bio-health through digital literacy in health. The objectives of this study were to determine the level of eHealth literacy, scientific knowledge in health and confidence on the part of students, analyzing the degree of improvement following a teaching intervention with students of the Bachelor’s Degree of Education of the University of Extremadura. A quasi-experimental longitudinal study was carried out with pre-test and post-test groups and a mixed data analysis. It involved the application of an active cooperative methodology with tutoring using the jigsaw technique, with the use of four quality digital browsers to enhance scientific rigor. The results show that the initial level of eHealth literacy and confidence was problematic. Following the intervention with the cooperative methodology, both these levels and the level of scientific knowledge in health reached an excellent level. In conclusion, this suggests that university training programs need to be implemented to improve digital and scientific skills in health education as they are currently insufficient. It has been demonstrated that a cooperative active methodology improved these levels and accordingly its use in active and digital higher education should be promoted.

The objective of this study was to characterise the changes in the Pedagogical Content Knowledge (PCK) about electric fields of two Colombian physics teachers (Isabel and Alejandro) at the high school level (pupils of ages 17–19), the emotions and their relationship with PCK. The research was conducted during two consecutive years, before and after their participation in a project of innovation on teaching electric fields. The method proposed corresponds to the descriptive type of case study. The PCK-related categories were grouped into two basic tendencies – traditional teacher-centred (TT) and pupil-centred or innovative tendency (TC) – plus an intermediate tendency (TI). The results indicated that, for Isabel, the PCK components that show the greatest progression over time are curricular knowledge and teaching strategies, evolving from a teacher-centred PCK to another which does not have a defined tendency. Alejandro, whose starting point was a PCK corresponding to an intermediate tendency in curricular knowledge, was less willing to change, especially with regard to his knowledge about teaching strategies. Finally, the causes of both the positive and the negative emotions are mostly related to the curricular knowledge and the content being taught.

The purpose of this paper is to address the most significant contributions of pedagogical content knowledge (PCK) involved in teaching physics. Most studies have observed the characterizations of PCK via specific content in the lower secondary and upper secondary curricula. Here, we present a number of studies that show evidence for the development of some PCK components, including those that present PCK as an articulating axis for physics teacher training models. The present work is a descriptive study that analyzes, by means of a case study, the changes in PCK through a physics teacher training intervention program. This program is based on reflections about teaching, concerning the electric field in physics education. The results show that categories, such as knowledge about the curriculum and teaching strategies, evolved after the intervention program, in contrast with knowledge about evaluation and pupils. This suggests that an approach involving a teacher’s reflection on what he/she designs allows for progression towards a teaching and learning process that is more focused on innovative tendencies.

In the contemporary era, Computational Thinking has emerged as a crucial skill for individuals to possess in order to thrive in the 21st century. In this context, there is a need to develop a methodology for cultivating these skills within a science and mathematics content education framework, particularly among pre-service teachers. This study aimed to investigate the impact of Educational Robotics on the development of Computational Thinking skills, with a particular focus on the role of gender, through a scientific and mathematical content teaching approach. A pre-experimental design with a quantitative approach was employed, and it was implemented with a total of 116 pre-service teachers, 38 males and 78 females. The results demonstrated a notable enhancement between the pre-test (8.11) and post-test (9.63) scores, emphasising specific concepts such as simple functions, while, and compound conditional. With respect to gender, statistically significant differences were identified prior to the intervention, but not following its implementation. The high level of Computational Thinking exhibited by both genders was comparable (53.85% in females and 55.26% in males) following the intervention. This indicates that the intervention is a promising approach for enhancing Computational Thinking proficiency, independent of gender and initial proficiency levels. The implementation of Educational Robotics in the teaching of science and mathematics enables the enhancement of Computational Thinking abilities among pre-service teachers, while reducing the observed gender disparity in this area of skill development.
