Digital technology to support students’ socioscientific reasoning about environmental issues

Scientific expertise and outcomes often give rise to controversy. An educational response that equips students to take part in such discussions is the teaching of socially acute questions (SAQs). With SAQs, the understanding of uncertainty, risk and how knowledge is developed is central. This study explores the way in which students from different disciplines and different continents are brought together via a digital platform to explore SAQs about environmental issues (a green algae outbreak linked to release of fertilisers along the coast of Brittany; the construction of a desalination plant near Melbourne to produce freshwater; and changes in meat consumption on a global scale, with regard to population projections in 2050). We have developed frameworks for looking at the quality of the collective reasoning and at the nature of students’ interactions, so that we can analyse the organisation of the learning communities and the building of collegial expertise. The results show that interdisciplinary discussions, especially on an international scale, foster the understanding of complex situations. In this paper, we discuss the modalities of one didactic scenario to enhance critical thinking and collaborative work, and to provide space for learners to support argumentation.

Cross cultural exchange to support reasoning about socio-scientific sustainability issues

In this article, we describe a project on reasoning about socio-scientific issues (SSIs), involving French and Australian pre-service science teachers engaged in on-line discussion and development of a wiki. In the research, we developed frameworks for looking at the quality of reasoning about 'socially acute' sustainability questions. We found the level of reasoning was enhanced by the cross-cultural exchange, and identified the importance of context in framing reasoning quality. We argue that science teachers could effectively adapt this approach to develop students' scientific literacy and embed the 'science as a human endeavour' strand of the Australian Curriculum in their practice.

Developing noticing of reasoning through demonstration lessons

Observation of fellow educators conducting demonstration lessons is one avenue for teachers to develop sensitivity to noticing students’ reasoning. We examined teachers’ noticing of children’s learning behaviours in one demonstration lesson of the Mathematical Reasoning Professional Learning Research Program (MRPLRP). The observations of teachers evident in the audio-taped post-lesson group interviews conducted at one school are reported in this paper. The teachers noticed that the children struggled to employ mathematical language to communicate their reasoning and expressed concern about gaps in children’s understanding of key mathematical concepts. The teachers viewed limitations in language and mathematical conceptual understandings as a barrier to effective reasoning.

A framework for teachers’ knowledge of mathematical reasoning

Exploring and developing primary teachers’ understanding of mathematical reasoning was the focus of the Mathematical Reasoning Professional Learning Research Program. Twenty-four primary teachers were interviewed after engagement in the first stage of the program incorporating demonstration lessons focused on reasoning conducted in their schools. Phenomenographic analysis of interview transcripts exploring variations in primary teachers’ perceptions of mathematical reasoning revealed seven categories of description based on four dimensions of variation, establishing a framework to evaluate development in understanding of reasoning.

A primary teacher's developing understanding of mathematical reasoning

To support teachers in their quest to incorporate reasoning as a mathematical proficiency as espoused in the Australian Curriculum: Mathematics, a professional learning research project using demonstration lessons was carried out. This paper reports on the impact of demonstration lessons on one participating teacher’s pedagogical knowledge about reasoning. The growth in this teacher’s knowledge was analysed using a phenomenographic framework established to evaluate teachers’ development in mathematical reasoning. The results show that demonstration and subsequent trial lessons contributed to her growth.
