The glue that makes it “hang together”: A framework for identifying how metadiscourse facilitates uncertainty navigation during knowledge building discussions

Classroom discussions have become a centerpiece of reform efforts in science education because talk mediates the joint co-constructing of knowledge in science classrooms. Although decades of research underscore the importance of talk in supporting science learning, the science education community continues to grapple with how to support teachers and students in navigating the uncertainty that is associated with doing knowledge building work. To address these challenges, we must examine not just what gets constructed (the scientific ideas), but how knowledge is co-constructed by teachers and students (the process of building those ideas) amidst uncertainty. In this study, we propose a conceptual tool for identifying organizational, epistemic, and interpretive metadiscourse markers (MDMs) in science talk. We highlight how teachers and students use these three types of MDMs as they navigate uncertainty while connecting ideas within and across multiple turns of talk, leveraging resources for knowledge building, and making interpretations about one another's ideas. We conclude with a set of suggestions for how researchers and teachers can utilize this framework to attend to the ways that MDMs index the organizational, epistemic, and interpretive dimensions of uncertainty in the knowledge building process.     

Uncertainty in information seeking and retrieval: A study in an academic environment

This research focuses specifically on uncertainty and information seeking in a digital environment. In this research we argue that different types of uncertainty are associated with the information seeking process and that, with the proliferation of new and different search tools, sources and channels, uncertainty, positive/desirable or negative/undesirable, continues to be a significant factor in the search process. Users may feel uncertain at any stage of the information search and retrieval process and uncertainty may remain even after completion of the process resulting in what may be called persistent uncertainty. An online questionnaire was used to collect data from users in the higher education sector. There were three parts to the questionnaire focusing on: information seeking activities, information seeking problems, and access to specific information channels or sources. Quantitative analysis was carried out on the data collected through the online questionnaire. A total of 668 responses were returned from the chosen user categories of academic staff, research staff and research students. This research has shown that there are some information seeking activities and information seeking problems that are the most common causes of uncertainty among significant number of users from different disciplines, age, gender, ICT skills, etc. This is also the case with respect to access to and use of specific information sources/channels, although the degrees of uncertainty in relation are relatively small. Possible implications of this study and further research issues are indicated.

Inside the ‘body box’: exploring feedback in higher education

In recent years, educational research has paid special attention to teachers’ practical-operative experience. The growing interest in the concept of practice within workplace settings has become a turning point in sociological, anthropological and educational studies. The present study aims to explore lecturers’ perceptions and conceptions of feedback and their daily professional practice, with a focus on the use of body movement while providing feedback during the class. Even though educational research has paid a lot of attention to the concepts of practice and performance, there are very few studies that consider the main actor included in the definition of those concepts: the body. Methodologically this exploratory case study uses a mixed methods approach. Results identified two types of issues: the first one concerns the relation between lecturer and students during the feedback practice; the second one concerns the internal coherence of lecturers between the kind of verbal feedback they provide during the lesson and how at the same time they act bodily.     

Down Syndrome Temperament: The Stereotype at Middle Childhood and Adolescence

MOTHERS AND TEACHERS of 94 children (53 boys) with Down syndrome, between 8 and 14 years of age, rated the children on a temperament scale and provided an overall impression as to whether the child was difficult in comparison with other children. Maternal ratings on the Middle Childhood Questionnaire showed significant differences from standardization scores. Children with Down syndrome were given ratings as less active, more predictable, of more positive mood, less persistent, and more distractible. Some of these dimensions favour the amiable personality stereotype for the syndrome but low persistence was associated with maternal impressions of difficulty. There was little agreement between mothers and teachers regarding the individual children who were rated as being significantly easier or more difficult than other children. Results with a subgroup (n = 32) showed that externalizing behaviours were significantly related to both mother and teacher impressions of difficulty and that mothers also found intense, active, distractible behaviour difficult.     

Connecting initial teacher education and continuing professional learning through action research and action learning

This paper reflects our commitments as teacher educators to develop the skills, knowledge and interests amongst ‘nearly qualified teachers’ to establish action learning as an integral part of their professional practice. We outline the development of an undergraduate unit that is endeavouring to achieve this at Edith Cowan University, Western Australia. Key principles and characteristics of action research and action learning are used as a framework for critical reflection on the unit. Attempting to provide learning experiences that adhere to these principles within the context of initial teacher education courses is identified as a challenging process. Planned developments in which we seek to enhance the extent to which teacher education can be seen to embrace and promote action research and action learning are discussed.
