Data modelling with first-grade students

This paper argues for a renewed focus on statistical reasoning in the beginning school years, with opportunities for children to engage in data modelling. Results are reported from the first year of a 3-year longitudinal study in which three classes of first-grade children (6-year-olds) and their teachers engaged in data modelling activities. The theme of Looking after our Environment, part of the children’s science curriculum, provided the task context. The goals for the two activities addressed here included engaging children in core components of data modelling, namely, selecting attributes, structuring and representing data, identifying variation in data, and making predictions from given data. Results include the various ways in which children represented and re-represented collected data, including attribute selection, and the metarepresentational competence they displayed in doing so. The “data lenses” through which the children dealt with informal inference (variation and prediction) are also reported.     

The role of cognitive engagement in classroom learning and motivation

The article analyzes the concept of student cognitive engagement, and the manner in which classroom instruction may develop self‐regulated learners. Since theory and research on academic motivation, to date only vaguely define the role of learning processes, and since studies of learning strategies rarely assess motivational outcomes, our analysis integrates these two streams of literature. We also identify specific features of instruction and discuss how they might influence the complex of student interpretive processes focal to classroom learning and motivation. Measurement issues and research strategies peculiar to the investigation of cognitive engagement are addressed.     

Deciding How to Deceive: Differences in Communication and Detection Between Good and Bad Liars

To study deception, participants were randomly assigned the role of allocator or recipient in an ultimatum negotiation game. Allocators “earned” 7 dollars and divided the money between themselves and recipient and communicated the decision either face-to-face or through text chat. Recipients were unaware the amount the allocator had, and therefore, allocators could deceive. Most allocators used deception. We hypothesized that participants who self-identified as good liars would communicate more face-to-face than through text chat when deceiving, and this was supported for deceptive omission but not fabrications. Good liars were more likely to have their truths correctly detected than bad liars.     

Globalisation and science education: the case of Sustainability by the Bay

It is impossible to consider contemporary science education in isolation from globalisation as the dominant logic, rethinking and reconfiguring social and cultural life in which it is located. Carter (J Res Sci Teach 42, 561–580, 2005) calls for a close reading of policy documents, curriculum projects, research studies and a range of other science education texts using key concepts from globalisation theory to elucidate the ways in which globalisation shapes and is expressed within science education. In this paper, we consider an example from our own practice of a school-based curriculum project, Sustainable Living by the Bay, as one such instance. The first section reviews neoliberalism and neoconservativism necessary to understand how globalisation penetrates education, while the second outlines aspects of the curriculum project itself. As there were many different facets to the development and implementation of a project like Sustainable Living by the Bay, there is space only to elaborate two examples of the globalisation discourse. The first example concerns the government policy initiative that funded the project while the second example focuses on learner- centred pedagogies as globalisation’s pedagogies of choice.     

Cultural factors in decision-making about child physical abuse: identifying reporter characteristics influencing reporting tendencies

OBJECTIVE: This study examined cultural factors that may influence child physical abuse reporting. Relevant cultural factors such as the respondents' ethnic identity and corporal punishment acceptability were investigated as proximal variables of ethnicity that affect child physical abuse reporting tendencies. METHOD: Participants consisted of 378 Caucasian, Hispanic, and African American college students. Participants read 12 vignettes that varied the ethnicity of the child and described a parent using physical punishment with the child. Participants' level of ethnic identity and their acceptance of different discipline practices were also assessed. Data were analyzed using multiple regression procedures. RESULTS: The ethnicity of the respondent was a significant predictor of reporting tendencies for African American respondents only. For African Americans, higher levels of ethnic identity and acceptance of corporal punishment were significant mediators of reporting tendencies, which influenced the relationship between ethnicity and likelihood to report a child of the same ethnicity. CONCLUSION: The results of this study indicate that ethnic minorities may not share similar cultural values and may differ in their degree of adherence to certain cultural variables. These results demonstrate how cultural variables that influence reporting tendencies may not apply across ethnic groups. Therefore, specifying relevant cultural variables is essential to understanding the relationship between ethnicity and reporting tendencies.     

Promoting literacy in a digital age: approaches to training for information literacy

Information literacy, and other similar ‘literacies’, such as digital literacy, mediacy, and informacy, are concepts relating to knowledge, skills, and attitudes, at various levels, in dealing with information in varied formats and diverse situations. The breadth of scope of these concepts implies that training must be equally broad, varied, and context-sensitive. This is exemplified by two case studies of information and digital literacy training. The first is a training programme in information literacy for the scientific staff of a multinational pharmaceutical research organization. The second is a summer school dealing with digital literacy, primarily for information professionals from countries of Central and Eastern Europe, and the former Soviet Union.
