This research aimed to know the Changes in Physics and Chemistry teachers’ practices on the use of scientific representations in a lesson study. A qualitative methodology with interpretative orientation was used. Participants were three pre-service Physics and Chemistry teachers involved in a Lesson Study. Data were collected through participant observation, individual written reflections and individual intervi...
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 co...
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 stude...
Background: Lesson Study is a collaborative model of teacher professional development that has received increasing international attention from many points of view. Objectives: This research aim to contribute to understand the effect of Lesson Study on the pedagogical content knowledge of the pre-service teachers on the speed of sound, at 8th grade. Design: This research is a qualitative and interpretative stud...
Los currículos de ciencias destacan la necesidad de implicar al alumnado en temas de la sociedad civil relacionados con las ciencias, al poner en evidencia la primacía de los aprendizajes sobre la relación cienciastecnología-sociedad-ambiente. Este trabajo tiene como objetivo conocer los aprendizajes de los alumnos cuando se involucran en el intento de solución de la problemática relacionada con la contaminació...
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 pres...
This research aimed to understand what a group of physics and chemistry preservice teachers in initial teaching education learn while used multiple representations, in the teaching of kinetic energy, in a lesson study. This lesson study was carried out within a master’s degree course in physics and chemistry teaching and involved three preservice teachers. The results showed that the preservice teachers learnt ...
Esta investigação teve como objetivo conhecer as aprendizagens dos futuros professores sobre o uso das múltiplas representações no ensino da energia cinética de um corpo, num estudo de aula. Os participantes foram três futuros professores de física e química. O estudo de aula decorreu numa unidade curricular do segundo ano do seu mestrado. Os resultados mostraram que os futuros professores usaram as múltiplas r...
Neste estudo elaboraram-se oito tarefas de investigação que pretendem capacitar os alunos a agirem coletivamente nas questões socio-ambientais e socio‑científicas. O estudo apresenta como finalidade conhecer quais são as potencialidades das tarefas na capacitação dos alunos em ações coletivas em torno dessas questões. Insere-se no paradigma interpretativo e são participantes uma professora de ciências e 21 alun...
