Integrated STEM education (iSTEM) has attracted attention due to its potentialities regarding students’ learning and intentions pursue STEM-related careers. However, although increasingly popular, iSTEM remains challenging elusive, particularly from teachers’ perspective. This scenario became even more complex with the inclusion of “A”, Arts. Considering that quality teachers is decisive in success integrated STEAM (iSTEAM), it essential provide opportunities develop their Pedagogical...

Social cognitive career theory posits that interests and decisions are influenced by individual, contextual, behavioural factors. This research aims to assess the impact of Science, Technology, Engineering, Mathematics (STEM) activities on students’ interest aspirations in STEM careers. Additionally, study explore critical factors might shape aspirations. The used a quantitative approach, with pre- post-test measures for cohort 191 Portuguese secondary school students, using Career Interest...

Purpose This research aims to examine the pre-service teachers’ learning when using STEM tasks with middle school students in a lesson study. Design/methodology/approach adopted qualitative methodology an interpretative orientation. The participants are three teachers involved study that took place curricular unit of master’s program physics and chemistry teaching. Data were collected through observation written reflections. Findings study, conducted as part initial teacher training, allowed...

Problem-Based Learning has been recognized as a fundamental approach in Science Education. Studies show that the success of this depends on students’ ability to self-regulate their learning and teacher feedback. However, research how these aspects interact formal science teaching contexts remains limited. This study aims address gap by investigating two questions: What self-regulation strategies are used different student groups while solving problem water hardness? How does feedback...

Abstract Background Electricity is a central concept in science curricula at all levels of education. Nevertheless, its invisible nature makes the concepts associated with it very difficult for students. Moreover, students have many alternative conceptions about related to electrical circuits. This study aims know effect STEM (Science–Technology–Engineering–Mathematics) approach on students' cognitive structures topic circuits, as revealed through Word Association Test (WAT). A following...

This study aims to explore how a learning sequence designed with an Integrated STEAM Education perspective (iSTEAM) contributes students’ levels of creativity. The participants in this were students from 9th and 10th grade ages between 14 16 years old. Students challenged produce soundtrack for animation video. was achieved by building artifacts using the phenomena physics under (mechanical energy) sound effects. These later digitally recorded assembled build video’s soundtrack. research...

The purpose of this study was to understand how the use multiple representations (MR), during a sequence lessons on saponification reaction, can help students develop their cognitive structures. We examined (i) effect teaching with MR development students’ structures and (ii) how, according students, that helped them This conducted in three Grade 12 classes, including total 68 students. follows pre-experimental one group pretest–posttest design, providing an intervention experiment. used two...

Abstract Mechanistic reasoning is a powerful form of central to scientific explanations. Despite mechanistic being an important dimension practice and science curricula, students face difficulties in developing such type reasoning. Many authors have been proposing tools for supporting its development; drawing one tool. Studies that purposefully explore how leverages supports students' while engage process constructing explanations are still scarce. The goal the current study was understand...

O estudo de aula é um processo formativo que leva os professores a refletirem, através trabalho eminentemente colaborativo, sobre sua prática profissional. Trata-se uma experiência envolve três momentos principais: planejamento, observação da aula, e reflexão pós-aula seguimento. seu objetivo criar condições para maior compreensão dos processos raciocínio alunos por parte e, assim, contribuir o desenvolvimento Neste artigo, analisamos as possibilidades formativas estudos no se refere às...

STEM (Science-Technology-Engineering-Mathematics) education has received great attention in recent years not only for promoting interest and learning these areas but also encouraging children young people to pursue careers them. This research explored the effects of a program developing primary pre-service teachers’ Content Knowledge (CK) Pedagogical (PCK) about sound. A qualitative interpretative study analyzed impact on CK PCK 18 teachers that were attending master’s degree Portuguese...

Since the widespread introduction of Information and Communication Technology (ICT) in education use multimedia environments has increased substantially. This qualitative study analyse how teachers integrate tools into teaching learning sequences (TLS) science education. Four in-service teachers’ groups have been investigated across a 40 h training course to their pedagogical strategies difficulties for introducing teaching. During program discuss (n=14) were invited build about some content...

Science education research emphasizes the need to engage students in socio-scientific issues, empowering them act a substantiated manner. This study aims understand potential of collective action initiative, focused on decreasing honey production issue, and students’ empowerment for action. A qualitative methodology was used with an interpretative stance. The participants were 26 3 rd grade their teacher. Data collected from written documents, through interview Results show that engagement...

Mobilizing scientific knowledge for understanding the natural world and critically appraise socio-scientific situations make decisions are key competencies todays' society. Therefore, it is essential to understand how students at end of compulsory schooling use surrounding world. The objective this study construct a scientifically oriented explanation while making sense phenomenon related health. We analysed 526 answers question Portuguese national 9th grade science exam. results reveal that...

Purpose The purpose of this paper is to understand what physics and chemistry preservice teachers learn on the nature inquiry tasks about classroom communication in an task when they take part a lesson study. Design/methodology/approach This qualitative interpretive research which was carried out within master’s degree course teaching with three teachers. Data were collected from participant observation video recording, interviews, written reflections group report by two-cycle study...

This research aims to examine: (a) how Physics teachers who participated in a STEM project, adopted and implemented activity the context of pandemic; (b) from perspective teachers, what were effects on students' learning (c) challenges had faced implementing during pandemic. A qualitative interpretive methodology was used. The participants are four sound, Data collected through interviews written reflections. study has shown how, crisis such as COVID-19, which affected schools all around...

Drawing is recognized as a powerful tool to learn science. Although current research has enriched our understanding of the potential learning through drawing, scarce attention been given social-cognitive interactions that occur when students jointly create drawings understand and explain phenomena in This article based on distributed embodied cognition theories it adopted notion we-space, defined complex space, dynamically established managed during ongoing individuals, they manipulate...

This investigation adjusted the lesson study (LS) model for initial teacher education aiming to examine its effect in development of pre-service teachers' pedagogical content knowledge (PCK) namely, both their and understanding on how transform a science topic make it more understandable students. The LS was speed sound that is taught 8th grade. PCK construct evaluated, as well terms PCK-topic specific PCK-pedagogical knowledge. participants this were three teachers. data collected through...
