Orthography and the development of metalinguistic reflection in Portuguese primary school pupils / Ortografía y desarrollo de la reflexión metalingüística en alumnos portugueses en primaria

Abstract

Linguistic awareness is crucial in learning literacy. This project has a two-fold aim: to develop the students’ ability to think about language in order to write with accuracy and to lead teachers to promote students’ discussions about their writing difficulties. The study is part of a two-year action-research project developed in primary schools from the Lisbon area, with experimental and control groups. The starting point of the project was the analysis of the problems students of third and fourth grades showed in their writing. The scope of the project includes dictation tasks within an interactionist approach, favouring grammatical discussions leading to the observation and manipulation of linguistic data.     

Online educational videos according to specific didactics: the case of mathematics / Los Vídeos educativos en línea desde las didácticas específicas: el caso de las matemáticas

Abstract

The vast number of online educational videos available at the moment has generated an emerging area of research concerning their level of suitability. This study considers the epistemic quality of educational videos on mathematics, focusing on the specific content of directly proportional distributions. A qualitative study is used, based on the application of theoretical and methodological tools from the onto-semiotic approach to knowledge and mathematics instruction, principally the notion of epistemic suitability and the identification of algebraic levels. The sample consists of the 31 most popular videos in Spanish on YouTube? on directly proportional distributions. Analysis reveals interesting results on these kinds of resources. In general, it is observed that they are weak in epistemic suitability, which does not seem to affect their level of popularity. Moreover, the existence of videos with inaccurate arguments or incorrect procedures, together with the diversity of algebraic levels used, indicates that teachers should be careful when selecting them and only recommend those that better suit their students’ needs.

What do we know and where do we go? Formative assessment in developing student teachers’ professional learning of teaching science

In the context of teacher education, it could well be suggested that assessment activities that build on formative interactions between student teachers and teacher educators might offer new windows into better understanding teaching and learning. This paper presents findings from a study into a primary science teacher education initiative that seeks to build the foundations on which 24 primary science student teachers, through the use of formative assessment of their science teaching and learning, can begin developing their pedagogical content knowledge (PCK). In the project, formative assessment consists of activities used by teacher educators to stimulate interactions, self- and peer-assessment in order to provide insights into how student teachers develop their PCK during a semester. Content Representations (CoRes), were used as a tool to unpack the student teachers’ approach to teaching a science topic and the reasons for that approach. The results indicate that the use of CoRes, together with subsequent self-assessment and formative interactions with teacher educators and peers, do have the potential for PCK development for student teachers. The results further highlight the need for developing reliable and valid tools for capturing and assessing student teachers’ PCK in pre-service teacher education.
