Teaching students to use and interpret different representational tools is critically important if they are to be scientifically literate, to understand how scientific ideas and concepts are represented and to appreciate how scientists think and act. Moreover, students not only need to be competent at using and explaining representations and learning new representations quickly but they also need to have opportunities to work cooperatively with others as it is through interactions between learners, tools and the environment that learning occurs. The current case study (part of a larger study) aimed to: (a) identify the effects of different teacher-introduced representational tools on students’ conceptual understandings, dialogic processes, motivation and learning; (b) examine the representational tools used by students during their inquiry science; and (c) examine the physiological states indicative of engagement and cooperation during learning activities. Prior to and on completion of the curriculum unit, participants completed a series of measures to assess actual as well as self-perceived ability in science. Students also wore wireless wristbands to measure autonomic arousal level that were analysed to assess the level of synchrony in physiological states between children. The results showed that the teacher successfully used embodied representations to engage the students in the science unit and maintained their focus in the cooperative groups by using language that encouraged on-going participation in the task. In turn, the students remained on-task and the majority of the language they employed was used to construct and communicate their scientific understanding to others. This high-level common engagement during whole class activities and student-centred learning during the cooperative group activities were also reflected in the physiological measures of synchrony between students. By integrating the video and biometric data with the data from the individual assessments, we construct a rich picture of relationship between the teacher’s use of multimodal representations and cooperative small groups with the students’ use of scientific language, physiological engagement and their beliefs and attitudes towards science.

. Her research activities focus on the selfregulatory processes of adolescent behaviour and child and adolescent emotional and behavioural difficulties. She has been particularly concerned with developing innovative multimedia methods and strategies for enhancing the engagement and motivation of at-risk children and youth to bring about positive change in their lives.

This study 4Identity formation and social development are key components occurring during adolescence.

Purpose Student competency in science learning relies on students being able to interpret and use multimodal representations to communicate understandings. Moreover, collaborative learning, in which students may share physiological arousal, can positively affect group performance. This paper aims to observe changes in student attitudes and beliefs, physiology (electrodermal activity; EDA) and content knowledge before and after a multimodal, cooperative inquiry, science teaching intervention to determine associations with productive science learning and increased science knowledge. Design/methodology/approach A total of 214 students with a mean age of 11 years 6 months from seven primary schools participated in a multimodal, cooperative inquiry, science teaching intervention for eight weeks during a science curriculum unit. Students completed a series of questionnaires pertaining to attitudes and beliefs about science learning and science knowledge before (Time 1) and after (Time 2) the teaching intervention. Empatica E3 wristbands were worn by students during 1 to 3 of their regularly scheduled class sessions both before and after the intervention. Findings Increases in EDA, science knowledge, self-efficacy and a growth mindset, and decreases in self-esteem, confidence, motivation and use of cognitive strategies, were recorded post-intervention for the cohort. EDA was positively correlated with science knowledge, but negatively correlated with self-efficacy, motivation and use of cognitive strategies. Cluster analysis suggested three main clusters of students with differing physiological and psychological profiles. Practical implications First, teachers need to be aware of the importance of helping students to consolidate their current learning strategies as they transition to new learning approaches to counter decreased confidence. Second, teachers need to know that an effective teaching multimodal science intervention can not only be associated with increases in science knowledge but also increases in self-efficacy and movement towards a growth mindset. Finally, while there is evidence that there are positive associations between physiological arousal and science knowledge, physiological arousal was also associated with reductions in self-efficacy, intrinsic motivation and the use of cognitive strategies. This mixed result warrants further investigation. Originality/value Overall, this study proposes a need for teachers to counter decreased confidence in students who are learning new strategies, with further research required on the utility of monitoring physiological markers.
