An instrument for analysing students’ argumentative reasoning when participating in debates

The aims of this paper are twofold. First, we present, justify, and characterise an instrument for analysing students’ argumentative reasoning developed from Walton’s ideas. Then, from the analysis of students’ argumentative discussion about a socio-scientific controversy, we identify the advantages and disadvantages of using the instrument. The results show that the analysis of students’ argumentative reasoning require nine stages, which have logical and pragmatic criteria that should be used in order to decrease the subjectivity of the analysis. The analysis sheds light on the characterisation of students’ argumentative reasoning by supporting the understanding of the move of students’ argumentative clusters, since it enables us to understand that: the argumentative quality depends on the relations between arguments and other statements; and an argumentative cluster can be developed according to the frequency of refutations or attacks by means of questions involving its constituents. This is because when arguments, questions, and/or claims are evaluated, the individuals have the possibility of bringing other reasons and/or arguments that support them in the discussion. Therefore, the main contribution of this study is the development of an instrument, based on dialectical principles, that contributes to analyse students’ argumentative discuss and to support discussions of their argumentative quality.     

Invented spelling activities in small groups and early spelling and reading

Our aim was to assess the impact of an invented spelling programme conducted in small groups on children’s written language acquisition in Portuguese. We expected the experimental group to have better post-test results than the control group in spelling and reading. Participants were 160 preschool-age children who were randomly divided into an experimental and a control group. Their age, cognitive ability, knowledge of letters and phonological abilities were controlled. Children’s spelling and reading were evaluated in a pre- and a post-test. In-between, experimental group participated in an invented spelling programme in small groups and the control group in story readings. The experimental group showed better results in spelling and reading in the post-test than the control one. Different dynamics occurred in the small groups which had different impacts on children’s acquisitions. These results provide empirical support for the proposal that invented spelling should be incorporated into early literacy instruction.     

Learning the principles of simulation using the birthday problem

Using the famous Birthday problem, we present here a practical activity that allows students to perceive the basic reasoning behind simulation and explore its potential. Through a playful approach with probabilities, students are led along a path that illustrates difficulties with intuition and introduces them to theoretical results for sample proportions.     

Empowering teachers to implement innovative content in physical education through continuous professional development

The purpose of this study was to examine teacher perceptions regarding their experiences in a research-informed continuous professional development (CPD) initiative and its influence on their professional readiness to implement innovative content in physical education (PE). Participants included four PE teachers who engaged in a series of hands-on workshops and collaborative activities related to the design and implementation of a mountain biking unit in two middle schools. Qualitative data were collected through post-workshop surveys, semi-structured interviews, and a focus group. Data were analyzed using inductive content analysis, and results revealed four themes: (a) igniting change, (b) transferring to the classroom, (c) student response, and (d) sustaining beyond a single unit. Findings from this study reinforce the need for research-informed CPD efforts in PE and highlight its role in generating a sense of teacher empowerment and promoting systemic change within school-based PE.     

Constructing and Using Multimodal Narratives to Research in Science Education: Contributions Based on Practical Classroom

This study deals with the problem of how to collect genuine and useful data about science classroom practices, and preserving the complex and holistic nature of teaching and learning. Additionally, we were looking for an instrument that would allow comparability and verifiability for teaching and research purposes. Given the multimodality of teaching and learning processes, we developed the multimodal narrative (MN), which describes what happens during a task and incorporates data such as examples of students’ work, photos, diagrams, etc. Also, it describes teachers’ intentions, preserving the nature of teaching practice in natural settings and it is verifiable and comparable. In this paper, we show how the MN was developed and present the protocol that was used for its construction. We identify the main characteristics of the MN and place it in the context of international research. We explore the potential of the MN for research purposes, illustrating its use in a research study that we carried out. We find that the MN provides a way to gather, organize and transform data, avoiding confusing and time-consuming manipulation of data, while minimizing the natural subjectivity of the narrator. The same MN can be used by the same or by different researchers for different purposes. Furthermore, the same MN can be used with different analysis techniques. It is also possible to study research practices on a large scale using MNs from different teachers and lessons. We propose that MNs can also be useful for teachers’ professional development.     

From Grounding Metaphors to Technological Devices: A Call for Legitimacy in School Mathematics

The mutual relationship between real objects and mathematical constructions is at the very base of studies concerned with making sense in mathematics. In this wider perspective recent research studies have been concerned with the cognitive roots of mathematical concepts. Human perception and movement and, more generally, interaction with space and time are recognized as being of crucial importance for knowledge construction. A new approach to the cognitive science of mathematics, based on the notion of ‘embodied cognition’ assumes that mathematics cannot be considered as mind free. Accordingly, mathematical concepts derive from the cognitive activities of subjects and are highly influenced by the body structure. This article reports some examples of teaching experiments based on body-related metaphors. Some of them are carried out by means of technological devices. A call for legitimacy in school mathematics is made, both for an embodied cognition perspective and for a related use of technology. This revised version was published online in July 2006 with corrections to the Cover Date.     

Does teacher homework feedback matter to 6th graders’ school engagement?: a mixed methods study

Metacognition and Learning - The effectiveness of homework on improving student academic achievement depends on several factors; for example, feedback provided by the teacher (i.e. grading) and...
