The role of peers and grades in determining major persistence in the sciences

Using longitudinal administrative data from a large elite research university, this paper analyzes the role of peers and grades in determining major persistence in the life and physical sciences. In the physical sciences, analyses using within-course, across-time variation show that ex-ante measures of peer quality in a student's introductory courses has a lasting impact on the probability of persisting in the major. This peer effect exhibits important non-linearities such that weak students benefit from exposure to stronger peers while strong students are not dragged down by weaker peers. In both the physical and the life sciences, I find evidence that students are “pulled away” by their high grades in non-science courses and “pushed out” by their low grades in their major field. In the physical sciences, females are found to be more responsive to grades than males, consistent with psychological theories of stereotype vulnerability.     

The relation between metastrategic knowledge,strategy use and task performance: Findings and reflections from a numerosity judgement task

In the research literature several positions concerning the role played by metacognition in adaptive strategy choice can be distinguished. While many authors adhere so-called metacognitive models of strategy choice and strategy change, others have questioned the extent to which metacognitive factors are associated with strategy choice and task performance and have proposed alternative theoretical frameworks wherein strategy choices are described in terms of associative models. In the present article we report data coming from a larger research project on the development of children’s numerosity judgement strategies and skills. The experimental task involved judging numerosities of colored blocks presented in a rectangular grid. Participants were 59 second grade and 50 sixth grade children, whose strategic performance data — obtained by means of a systematic analysis of their response-time patterns — were compared with interview data collected at the end of the experiment. The major result of this comparison is that not only the children from the oldest age group, but also the children from the youngest age group showed clear evidence of metacognitive awareness and understanding of different aspects of their strategic performance.     

Developing competent e‐learners: the role of assessment

We know assessment plays a major formative role in driving student learning appropriately, but what implications does this have for online courses? Is it more important than in a face to face context, or less so? Should we reconceptualize the ways in which we assess students, or are existing methods, tried and tested in conventional teaching and learning situations, appropriate? This paper discusses the practical implications of implementing these online pedagogies and illustrates the powerful formative effects, both intended and unintentional, of assessment on student learning and behaviour. It draws on examples from recent research on two e‐learning courses at UK Open University.     

The role of peers in the emergence of heterosexual romantic relationships in adolescence

Adolescents' peer structures and the quality of their friendships were explored as antecedents of romantic relationships. Longitudinal data were gathered in a sample of 180 high school students over a 3-year period from grade 9 to grade 11. Consistent with Dunphy (1963), small groups of close friends were predictive of other-sex peer networks which were, in turn predictive of the emergence of future romantic relationships. Indirect effects were found for same-sex groups of close friends and same-sex networks. Consistent with Furman and Wehner (1994), the qualitative features of relationships with both friends and romantic partners were predictive of the qualitative features of subsequent romantic experiences. These linkages suggest ways in which peer relationships may support romantic development at this stage of the life cycle.     

The role of private speech in the transition from collaborative to independent task performance in young children

This study was designed to examine the following central Vygotskian hypotheses about the functions of preschool children's private speech: (1) that private speech facilitates the transition from collaborative to independent task performance, and (2) that children's use of private speech is conducive to task success. Age-related changes in children's use of private speech were also examined. Forty preschoolers, ranging in age from three to five, completed a selective attention task with scaffolded assistance given from an experimenter when needed. In an effort to overcome several methodological limitations found in previous research, a new microgenetic method of analyzing speech-performance relations based on assigning task items to discrete categories reflecting six possible co-occurrences between private speech (item-relevant speech, item-irrelevant speech, silence) and performance (success, failure) was introduced. Results were that (1) item-relevant speech was used more often during successful than during failed items while the opposite was true for item-irrelevant speech; (2) children were more likely to use private speech on successful items after scaffolding than they were on similar items not following scaffolding; (3) after scaffolding, children were more likely to succeed on the next item if they talked to themselves than if they were silent; and (4) hypothesized curvilinear, age-related patterns in children's item-relevant private speech and silence were found, however, only when analyzing speech during successful items. Implications of this research for preschool teachers and parents are discussed.     

The relationship between temperament and social adjustment to peers

In recent years, evidence has accumulated indicating that peer relations constitute an essential component of child development. Although investigators have explored a number of factors that affect peer relations, few have considered the impact of temperament. The present study investigated whether temperament is related to a child's initial reactions to peers in a preschool setting and to changes in social behavior over time. The central hypotheses were confirmed: temperament was related to initial and later social behavior with peers. The theoretical and practical implications of the study are discussed.

Exploring the relationship between homework task difficulty,student engagement and performance

This article considers the relationship between differential homework task difficulty, student engagement and performance across four Irish post-primary school sites. A total of 236 participants completed all elements of this study. All participants were junior cycle students, aged between 12 and 16 years. The study employed a standardised test–retest approach, with a one week interval between tests. Between testing, participants were randomly subdivided into three cohorts. Each cohort received homework questions of different difficulty levels to complete for one week. The results of this study found that Cohort A, who received the least difficult homework tasks, completed the most non-compulsory questions. Although Cohort A demonstrated higher levels of engagement, no statistically significant difference was found in the change in performance scores of the three cohorts. The results highlight the negative impact of increased task difficulty on student engagement with independent homework tasks. The findings suggest that in order to support student engagement it is important that teachers afford ample opportunity for student success when designing self-directed tasks such as homework.

Children at play: the role of peers in understanding the effects of child care

Although the studies of the National Institute of Child Health and Human Development (NICHD) Early Child Care Research Network (this issue) and of Watamura, Donzella, Alwin, and Gunnar (this issue) identify the potential of child care to affect children's adjustment, how these effects are produced remains unclear. In this commentary, it is argued that there is a need to expand child care research by considering one of the most important, but unrecognized, contributors to child care effects-peers. Research is reviewed that suggests that children's interactions in same-sex peer groups at child care affect their short- and long-term adjustment. We consider how research on early peer influences can inform the findings of the NICHD Early Child Care Research Network and Watamura et al. studies, aswell as contribute to the next generation of child care research.     

Cross-lagged relations between task motivation and performance in arithmetic and literacy in kindergarten

To examine the cross-lagged relationships between children's task motivation in mathematics and literacy, and their related performance, 139 children aged 5–6 years were examined twice during their kindergarten year. The results showed that only math-related task motivation and arithmetic performance showed cross-lagged relationship: the higher the math-related task motivation children reported in the beginning of the kindergarten year the higher the level of their arithmetic performance at the end of the kindergarten year. Moreover, the higher the level of children's arithmetic performance the more the interest in mathematics children reported later on. Literacy-related task motivation and literacy performance did not show a similar pattern of relations.     

The role of emotions and task significance in Virtual Education

This paper analyzed the role of emotions in a virtual world (Second Life) through students' level of enjoyment and boredom and their influence on students' achievement level. The virtual world was an educational tool used to fully immerse students in the content of the course. In addition to supporting prior research on the importance of task value on academic enjoyment, the current research provides a new perspective on the relationship between academic emotions and academic success, particularly for virtual worlds. A regression analysis was conducted to measure the relationship of task value and emotions on two types of academic performance: Individual exam scores and team scores on their Second Life assignment. Pekrun's Academic Emotions Questionnaire (AEQ) was used to measure two academic emotions: boredom and enjoyment. Both academic emotions were measured on an individual level. Results from this study show that task value was positively related to enjoyment and negatively related to boredom, yet it was unrelated to academic performance. While enjoyment had a positive relationship to exam performance, boredom also had a positive relationship to the team assignment conducted in the virtual world. The possibility that students might have answered the AEQ relating to the theoretical aspects of the course instead of the practical aspects of the Second Life Assignment, may be one possible explanation for this result.     

The role of feedback in teacher mentoring: how coaches,peers, and students affect teacher change

ABSTRACT

Our study contributes to understanding teacher mentoring by exploring impacts of feedback from multiple mentoring sources as teachers with varying levels of experience learned to implement student-centered instruction. Mentees in our study learned to implement a student-centered model, supported by mentoring from students and teachers experienced in the model. We employed qualitative methods to collect and analyze data from two summer schools, with 22 STEM teachers and 47 student-instructors from 15 non-selective, public high schools. Findings include: (a) teachers had positive attitudes towards feedback, (b) feedback from multiple sources changed practice, (c) effective feedback required structure, (d) experienced teachers benefited most from feedback, and (e) student feedback was most valuable. These findings provide strategies to shape future mentoring, informing teachers, administrators, professional development coaches, and teacher educators about critical factors in the use of feedback to improve teaching through mentoring.     

Aggression between peers in early childhood: individual continuity and developmental change

43 children were observed in play with "best available friends" at 2 and again at 5 years of age. An arousing stimulus, an angry interaction between adults, was introduced during play sessions to increase the likelihood of elicitation of aggressive patterns. Dimensions of physical aggression at age 2 (e.g., object-related aggression, bodily aggression) predicted dimensions of children's physical aggression at age 5. However, substantial sex differences in the stability of aggression were found. Among boys, the disposition to engage in physical aggression was highly stable, with correlations ranging as high as r = .76. Certain dimensions of physical aggression at age 2 were also positively associated with verbal aggression at age 5. Fewer and more modest correlations were found among girls. The frequency of aggression, particularly bodily aggression (e.g., hitting, pushing), initiations of aggression, and the average length of aggression episodes, decreased between 2 and 5 years of age. These results indicate that relative aggressiveness tends to remain stable despite declines in the frequency of aggressive behavior between 2 and 5 years of age.     

Facilitating a positive sense of self in pupils with dyslexia: the role of teachers and peers

This article focuses on the changes in the educational environment for children with dyslexia which could help them to develop a positive sense of self. Neil Humphrey discusses the importance of the role of teachers and peers in this respect and suggests some key teacher and peer behaviours facilitating positive self‐esteem.

Effects of gender role and task content on performance in same-gender dyads: Transactive memory as a potential mediator

This experiment was designed to examine the effects of gender role and task content on performance in learning dyads and to test the potential mediator effect of an intragroup process related to transactive memory. A total of 44 same-gender dyads participated in the study and were asked to collaborate on a stereotypically masculine or feminine task in a laboratory setting. Collective performance and transactive memory were measured. As predicted, the results showed an interaction between group gender and task content on group performance, with male dyads showing poorer performance on a masculine task than female dyads. However, contrary to expectations, this moderation effect was not mediated by transactive memory, which appeared as a simple mediator of the relationship between group gender and performance. The results are discussed in the framework of the social role theory, and implications for future research in small learning groups are proposed.     

Factors moderating blocking in human place learning: The role of task instructions

Cognitive map theory assumes that novel environmental information is automatically incorporated into existing cognitive maps as a function of exploration. Reports of blocking in place learning cast doubt on this claim. In these studies, subjects were first trained to find a place, using a set of landmarks (Set A). Then novel landmarks (Set B) were added for additional trials. Subsequent removal of the Set A landmarks showed that the novel landmarks alone were insufficient for successful navigation. We investigated whether instructing human subjects to explore the environment can moderate blocking. First, we demonstrated that blocking is absent in a computer implementation of the Morris water maze (MWM) in which subjects are instructed to explore. We then studied why others found blocking in a different MWM implementation, in which the task instructions did not suggest exploration. In experiments that faithfully replicated this MWM variant, we found that subjects did not acquire cognitive maps and that blocking was attenuated when instructions were provided that encouraged exploration. Together, these findings indicate that blocking in human place learning may reflect a performance deficit, not a learning deficit, and that instructions can moderate blocking. Our results thus support the automatic update assumption of cognitive map theory.
