Metacognitive activity in the physics student laboratory: is increased metacognition necessarily better?

In this study natural-in-action metacognitive activity during the student laboratory in university physics is explored, with an aim towards quantifying the amount of metacognition used by the students. The study investigates whether quantifying natural-in-action metacognition is possible and valuable for examining teaching and learning in these contexts. Video recordings of student groups working during three types of introductory physics laboratories were transcribed and then coded using a coding scheme developed from related research on mathematical problem solving. This scheme identifies a group’s general behaviour and metacognitive activity. The study recognizes that reliably identifying metacognition is challenging, and steps are taken to improve reliability. Results suggest that a greater amount of metacognition does not appear to improve students’ success in the laboratory—what appears to matter is whether the metacognition causes students to change behaviour. This study indicates that it is important to consider the outcome of metacognition, not just the amount.

Teachers’ positioning towards an educational innovation in the light of ownership, sense-making and agency

The positioning of eleven teachers towards an innovation was studied in the light of ownership, sense-making and agency. Semi-structured and video-stimulated interviews were used for data collection. The findings show that these three concepts are useful for describing similarities and differences between teachers in terms of their positioning towards the innovation. Considerable differences were found between teachers regarding their ownership, sense-making, and agency. Exploring the relations between these concepts revealed that a high degree of agency often went together with a high degree of ownership, but seemed to be moderated by the sense-making process.     

Quality as sense-making

Sense-making is a process of engaging with complex and dynamic environments that provides organisations and their leaders with a flexible and agile model of the world. The seven key properties of sense-making describe a process that is social and that respects the range of different stakeholders in an organisation. It also addresses the need to account for the history and context of the organisation while also acting to change that context. This paper describes a conception of quality framed by sense-making. It explores the possible insights and guidance it can provide to leaders and others seeking a model aligning quality with forward-looking organisational change and capable of reflecting the complex relationships between educational organisations and their diverse stakeholders. Quality as sense-making flows from a recognition that education is too complex and too important to be defined by a small number of qualities relevant to a privileged group of stakeholders, or by limited performance indicators such as financial efficiency, instead it is experienced through an on-going conversation challenging complacency and the status quo.     

Hurtful Episodes in Parent–Adolescent Relationships: How Accounts and Attributions Contribute to the Difficulty of Talking about Hurt

This research examines sense-making about hurtful episodes between parents and adolescents and how sense-making processes relate to subsequent communication. Results highlight differences in the events parents and adolescents find hurtful and the complex forces that influence accounts for hurtful episodes. Children were less affected overall by hurtful episodes and provided more benevolent accounts of parents' hurtful actions and words. Parents demonstrated typical victim–perpetrator biases, particularly when relationship quality was low. Furthermore, findings provided evidence that sense-making about hurtful events may affect follow-up conversations. Intentionality attributions and the similarity of pre-interaction accounts predicted the difficulty and negativity of subsequent conversations, based on both perceived and observed ratings. Account similarity also predicted observed aspects of joint storytelling in the conversations.     

Use of evaluative devices by youth for sense-making of culturally diverse interpersonal interactions

Building upon recent research that defines psychological development as a continuous process of sense-making situated within a cultural and historical context, this paper explores how culturally diverse youth growing up in New York City use evaluative language to enact relational complexity as they make sense of technologically mediated interpersonal interactions with their peers. Forty-four individuals (ages 15–20) participated in a quasi-experimental research workshop that engaged them in the process of sense-making by asking them to write projective narratives toward a vignette depicting text-massage mediated interpersonal interaction embedded among monocultural and bicultural group of peers. Data analyses focus on evaluative devices used by youth and manifest the relational flexibility of sense-making by immigrant youth and their U.S. born peers across diverse relational dimensions. Results suggest that immigrant youth are able to coordinate diverse ways of interpreting interpersonal interactions across relational dimensions, manifest by varied use of logical/hypothetical, causal and affective evaluative devices. In contrast U.S. born youth largely use same frequency of evaluative devices across two relational dimensions. Statistical analysis highlights the use of affect in projective narratives by exploring a discursive learning hypothesis: that higher use of emotions in the process of sense-making by U.S. born youth gradually scaffolds the use of emotions in narrative by immigrant youth.
