Causal reasoning and inference making in judging the importance of story statements

The present study investigated the development of the ability to judge the importance of story statements on the basis of their causal properties. Key statements were varied with respect to 2 factors: in terms of the number of their causal relations, and in terms of the kinds of relations they had. Relations were either intraepisodic, that is, connecting statements in the same episode, or interepisodic, that is, connecting statements in different episodes. Children 8, 11, 14, and 18 years of age judged the importance of the statements. Children in all 4 age groups judged statements with many intraepisodic causal relations as more important than statements with few such relations. Only children 11 years and older judged statements as more important when they had interepisodic relations than when they did not. Thus, although young children may be sensitive to quantitative aspects of a statement's relational role within an episode, they may not be as aware of qualitative, that is, structural, differences between kinds of relations. Answers to why questions confirmed these patterns. Older children more often gave answers that crossed episodic boundaries than did the younger children. These findings may reflect age-related differences in children's ability to infer relations between statements and to integrate the information contained in stories. They also attest to the central role that causal inferences play in the interpretation of what is important information in stories.     

Engaging young students in scientific investigations: prompting for meaningful reflection

This study examined the verbal prompts a tutor used to promote reflection and young students’ responses to these prompts. Seven children (ages 8–12) participated in 260 min of one-on-one tutoring to learn scientific concepts related to gear movement; the tutor spontaneously provided these students with 763 prompts for reflection. Prompts reliably induced reflection: Students responded verbally 87% of the time. Turn-by-turn discourse analysis revealed seven distinct types of prompts and 11 distinct types of verbal responses. High-level prompts were strongly associated with high-level responses. A log-multiplicative association model with two dimensions (temporality and certainty) represented the relationships between prompt and response types; from this model, odds ratios estimated the strength of association between specific pairs of prompt and response types. Findings are discussed in terms of the effects that reflection may have on students’ developing understanding of scientific concepts.     

International trends in health science librarianship: part 1 - the English speaking world

This is the second in a series of articles exploring international trends in health science librarianship in the first decade of the 21st century. The invited authors were asked to reflect on developments in their country - viz. Australia, Canada, New Zealand and the United States. Future issues will track trends in Northern Europe, the Nordic countries, Southern Europe and Latin America. JM.     

Selection committee membership: Service or self-service

Project funding is an increasingly important mode of research funding. The rationale is that through project funding new fields and new themes can be supported more effectively. Furthermore, project funding improves competition, which is expected to select the better research projects and researchers. However, project funding has a price, as it requires researchers to invest time in reviewing proposals, and to participate in selection committees. In that perspective, selection committee membership can be seen as a service to the scholarly community.However, what do committee members themselves get from membership? In this paper we show that committee members in average are more successful in grant applications than other principle investigators, and this is not explained by performance differences. The findings suggest that committee membership is not only service, but also self-service.     

First-graders’ knowledge of multiplicative reasoning before formal instruction in this domain

Our study investigated children’s knowledge of multiplicative reasoning (multiplication and division) at the end of Grade 1, just before the start of formal instruction on multiplicative reasoning in Grade 2. A large sample of children (N = 1176) was assessed in a relatively formal test setting, using an online test with 28 multiplicative problems of different types. On average, the children correctly answered more than half (58%) of the problems, including several bare number problems. This indicates that before formal instruction on multiplicative reasoning, children already have a considerable amount of knowledge in this domain, which teachers can build on when teaching them formal multiplication and division. Using analysis of variance and cross-classified multilevel regression analysis, we identified several predictors of children’s pre-instructional multiplicative knowledge. With respect to the characteristics of the multiplicative problems, we found that the problems were easiest to solve when they included a picture involving countable objects, and when the multiplicative situation was of the equal groups semantic structure (e.g., 3 boxes of 4 cookies). Regarding student characteristics, pre-instructional multiplicative knowledge was higher for children with higher-educated parents. Finally, the mathematics textbook used in school appeared to have influenced children’s pre-instructional multiplicative knowledge.     

Access to academic curriculum in Australian secondary schools: a case study of a highly marketised education system

This study examines how access to academic curriculum differs between secondary schools in Australia, a country whose education system is marked by high levels of choice, privatisation and competition. Equitable access to academic curriculum is important for both individual students and their families as well as the larger society. Previous research has shown that students from lower socio-economic backgrounds are less likely to study academic curriculum than their more advantaged peers. Less is known, however, about the extent to which this pattern is related to differential provision of curriculum between schools. We found that low socio-economic schools offer students less access to the core academic curriculum subjects that are important for university entry. We also found that the breadth and depth of courses offered is related to school sector (private or public) and socio-economic context. Previous research has shown that choice and competition are inequitable because they frequently increase school social segregation and ‘cream-skimming’. Our findings show another inequitable consequence, namely that choice and competition limit access to high-status academic curriculum in working-class communities.     

The Effects of Social Support,Depression, and Stress on Drinking Behaviors in a College Student Sample

Social support research contends that supportive interactions provide a buffer wherein individuals are protected from increased risk due to negative affect. The present study investigated the relationships between social support and college students' stress, depression, and alcohol use. A total of 54 students completed questionnaires in exchange for extra course credit. Results demonstrated that stress and depression were correlated with one another and that social support was negatively correlated with each of these outcomes. Depression, but not stress, was correlated with increased drinking behavior. Overall, social support was negatively correlated with alcohol consumption; however, depression moderated the effect of social support such that support and alcohol consumption were negatively correlated for participants with higher depression whereas support and alcohol consumption were positively correlated for individuals with lower depression. These findings partially confirm existing theories of alcohol use that hypothesize differences between self-medicating drinkers and social, sensation-seeking drinkers.

In Defense of “Mass Communication” and Other Stuff

A consistent news frame that deligitmizes and depicts most social protests as "police vs. protesters" has been identified in studies of news coverage of social movements. This study used an experimental design to examine the extent to which photographs and prior attitudes toward protests and protesters in general contribute to previously identified framing effects of protest news. Results indicated that for the protest issue of interest evaluations of the protest and protesters were more negative when photos depicting higher levels of conflict were shown. The amount of conflict shown in the photos did not affect evaluations of the protest and protesters when the issue was of less interest to participants. Additionally, participants who had more positive prior attitudes toward protesting in general were more likely to identify with the protesters in the stimulus story and to perceive that the protest was more effective than were those with more negative prior attitudes. Findings suggest the need to address possible nuances associated with the visuals alone and to incorporate prior attitudes when examining effects of news coverage of protests.
