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

The purpose of this study was to understand how the use of multiple representations (MR), during a sequence of lessons on the saponification reaction, can help students develop their cognitive structures. We examined (i) the effect of the teaching sequence with MR on the development of the students’ cognitive structures and (ii) how, according to the students, that sequence helped them to develop their cognitive structures. This study was conducted in three Grade 12 classes, including a total of 68 students. This study follows a pre-experimental one group pretest–posttest design, providing an intervention during the experiment. We used two data collection instruments: a Word Association Test (WAT) and a focus group interview. The results obtained from the WAT show that the students’ cognitive structures progressed from the pretest to posttest, with an increase in the number of response words and connections between words, and with a change in the nature of these connections. The results suggest that this development was influenced by the way students used MR, making use of the three MR functions proposed by Ainsworth (2006, 2008). The students recognized that the combination of the three MR functions allowed them to move across representation levels (macroscopic, symbolic and submicroscopic) and to develop a deeper and more structured understanding of the concepts related to the saponification reaction.

This investigation adjusted the lesson study (LS) model for the initial teacher education aiming to examine its effect in the development of the pre-service teachers’ pedagogical content knowledge (PCK) namely, both their knowledge and understanding on how to transform a science topic to make it more understandable for the students. The LS topic was the speed of sound that is taught in the 8th grade. The PCK construct was evaluated, as well as and in terms of both PCK-topic specific knowledge and PCK-pedagogical knowledge. The participants on this investigation were three pre-service teachers. The data were collected through video recording of LS sessions. The qualitative data collection was combined with quantitative and qualitative analysis procedures. The results showed that the LS promoted an improvement on pre-service teachers’ PCK as well as in most of the aspects of both PCK-topic specific knowledge and PCK-pedagogical knowledge. PCK’s aspect’ ‘Strategies for pupil self-evaluation’ has not improved satisfactorily. These findings suggest that LS should be carried out during the training programs of the science PSTs.

Purpose: The purpose of this paper is to understand what physics and chemistry preservice teachers learn on the nature of the inquiry tasks and about classroom communication in an inquiry task when they take part in a lesson study.Design/methodology/approach: This is a qualitative and interpretive research which was carried out within a master’s degree course in physics and chemistry teaching with three preservice teachers. Data were collected from participant observation with video recording, interviews, written reflections and group report by the preservice teachers. This two-cycle lesson study was conducted over 12 sessions. The data analysis took place through asking questions and using the constant comparison method, which allowed the identification of the most relevant issues about the preservice teachers learning according to the categories nature of the inquiry tasks and communication promoted by the teacher.Findings: The results show that the preservice teachers learnt to identify the characteristics of inquiry tasks, how to develop an inquiry task when planning the research lesson and acknowledged its potential for student learning. Moreover, the preservice teachers acknowledged the fact that the classroom communication promoted by the teacher fostered student participation, negotiation of meanings about scientific concepts and construction of new learning that can be shared within the class.Research limitations/implications: Research is needed as regards how initial teacher education providers may contribute to the learning of preservice teachers in lesson study in initial teacher education programmes.Originality/value: This research contributes to show potentialities of lesson study in the initial teacher education of preservice physics and chemistry teachers.

Multiple representations, such as experimental data, schemas, tables, and graphs, are an essential resource in science teaching. However, their use in the classroom typically poses a challenge for preservice teachers. The aim of this research is to examine changes in the practices of a group of preservice teachers regarding the use of multiple representations in the teaching of kinetic energy to 9th grade students, when this training is included in their initial teacher education program. For this purpose, a collaborative, reflexive, and student-learning centered approach, namely, a lesson study with three cycles, was implemented. A descriptive and content analysis for qualitative data collected showed improvement in the practices of the preservice teachers, namely on the representations both of the event that represents the “real” world, as well as of the scientific concepts. The results obtained contribute to deepening the knowledge on the use of multiple representations by preservice teachers, as well as to increasing the knowledge on using lesson study to develop the ability to use multiple representations during initial teacher education.

The lesson study is a collaborative model of teacher professional development originating in Japan, which has received growing international attention. This multifaceted model can be considered from many points of view. This research aims to understand what physics and chemistry pre-service teachers learn, in the domain of the pedagogical content knowledge on the speed of sound, in a lesson study. Participants were all pre-service teachers (three) attending the first year of their initial teaching education programme. The lesson study, had two cycles, took place over the course of twelve sessions and a total of 36 hours of work. The first cycle consisted of ten sessions: the first eight sessions aimed at defining the topic and lesson planning; this was followed by the first research lesson taught by the cooperating teacher; and finally, there was a post-lesson reflection. The second cycle consisted of two sessions; a second research lesson was also taught by the cooperating teacher; and subsequent to this, there was a post-lesson reflection. This is a qualitative and interpretative study. Data were collected from participant observation of all sessions using field notes and video recording, individual interviews and individual written reflections. Results showed that the pre-service teachers developed the pedagogical teacher knowledge (PCK) to teach the topic in the planning phase, when they identified the students’ prior knowledge, which would help them learn the topic, and in the post-lesson reflection sessions, when they discussed strategies that could help students overcome their learning difficulties.
