The transient role of explicit phonological recoding for reading acquisition

This study explores early stages of reading acquisition, specifically therelation of phoneme blending and letter recoding to individual differencesin word decoding. The hypothesis was that facility in letter recoding andaccuracy of phoneme blending are substantial components of word decodingin beginning readers but not for skilled reading and that reliance onphoneme-sized decoding of words would dissipate as reading proficiencyincreased. In four studies we examined the ability to recode letters, blendphonemes and decode words in four groups of Dutch children (early Grade1, N = 130, older Grade 1, N = 81, Grade 3, N = 54 and a group of children witha reading lag, N = 356). Phoneme blending was only related to the readingability of beginning Grade 1 children. By the end of Grade 1 ability to blendphonemes did not differentiate reading capacity, nor for older children inGrade 3 and reading disabled children. Letter recoding was related to worddecoding in all four studies, although the strength of that relation diddwindle as reading skill level increased. The results of the study appearconsistent with self teaching hypothesis and other theories that imply atransient role of explicit phonological recoding in word identification.     

A Longitudinal Study of Consistency and Change in Self-Esteem from Early Adolescence to Early Adulthood

In a longitudinal study of 47 girls and 44 boys, developmental change in self-esteem (SE) was examined from early adolescence through late adolescence to early adulthood. Males tended to increase and females tended to decrease in SE over time. There was appreciable rank-order consistency in SE over time. Within each gender, the considerable individual differences in developmental trajectories were coherently related to personality characteristics independently assessed in early adolescence. Boys and girls with high SE possessed quite different personality characteristics in early adolescence; by early adulthood, although important differences remained, the personality characteristics associated with high SE were similar for the 2 sexes. Discussion focuses on the implications of our findings for the "consistency versus change" debate, the influence of gender-role socialization on SE development, and the importance of examining normative, gender-specific, and individual developmental change in SE.     

Chinese adolescents' reasoning about democratic and authority-based decision making in peer,family, and school contexts

This study explored the judgments and reasoning of Chinese adolescents (13-18 years of age) from 3 regions of mainland China (N = 574) regarding procedures for making decisions involving children in peer, family, and school contexts. Participants evaluated 2 democratic decision-making procedures (majority rule and consensus) and decision making by adult authorities for 2 decisions embedded in each social context. Judgments and reasoning about decision-making procedures varied by social context and by the decision under consideration, and evaluations of procedures became more differentiated with increasing age. The findings reveal that concepts of rights, individual autonomy, and democratic norms (majority rule) are salient aspects of Chinese adolescents' social reasoning and are used to evaluate critically existing social practices.

‘The Use of History of Mechanics in Teaching Motion and Force Units’

This paper reports a 4-month study that investigated the effectiveness of curriculum materials incorporating the history of science (HOS) on learning science, understanding the nature of science (NOS), and students’ interest in science. With regards to these objectives, three different class contexts were developed with three main types of information in history of science. In the first class context, the similarities between students’ alternative ideas and scientific concepts from the HOS were considered in developing teaching materials. In the second class context, the teacher developed discussion sessions on the ways scientists produce scientific knowledge. In the third class context, short stories about scientists’ personal lives were used without connection to the concepts of science or NOS. Ninety-one eighth-grade students were randomly assigned to four classes taught by the same science teacher. The concepts in the motion unit and in the force unit were taught. Three of the four classrooms were taught using the contexts provided by the HOS while the fourth class was taught in the same way that the teacher had used in previous years. The effects on student meaningful learning, perceptions of the NOS, and interest in science were evaluated at the beginning, at the middle, and at the end of the study to compare differences between historical class contexts and the Traditional Class. Results of analysis showed that the changes in meaningful learning scores for the first class context were higher than other classes but the differences between classes were not significant. The HOS affected student perceptions of the scientific methods and the role of inference in the process of science. Stories from scientists’ personal lives consistently stimulated student interest in science, while discussions of scientific methods without these stories decreased student interest. The positive effects of stories relating scientist’ personal life on student interest in science has major importance for the teaching of science. This research also helps to clarify different class contexts which can be provided with different types and uses of historical information.     

Japanese and American children's evaluations of peer exclusion,tolerance of differences,and prescriptions for conformity

Children and adolescents (N = 1,057), divided by gender, at fourth, seventh, and tenth grades, from two mid-sized cities in the United States and in Japan, were surveyed regarding their evaluations of peer group exclusion of atypical peers. Six reasons for atypicality were being aggressive, having an unconventional appearance, acting like a clown, demonstrating cross-gender behavior, being a slow runner, and having a sad personality. Analyses revealed significant effects for age, gender, country membership, and the context of exclusion. With age, children demonstrated context sensitivity, and believed that the excluded child should not change him- or herself to be accepted by the group. Across contexts, girls were less willing to exclude than were boys, and were more tolerant of differences. The context of exclusion had an effect on all forms of judgments about exclusion, and there were very few overall effects for culture. Most children disagreed with the decision to exclude, believed that they were different from the atypical child, and believed that the excluded child should change him- or herself to be accepted by the group. The results support a theory of developmental social cognition in which multiple sources of influence have a significant effect on social decision making involving the exclusion of others.     

The social costs of academic success across ethnic groups

This study explores the longitudinal association between academic achievement and social acceptance across ethnic groups in a nationally representative sample of adolescents (N = 13,570; M(age) = 15.5 years). The effects of school context are also considered. Results show that African American and Native American adolescents experience greater social costs with academic success than Whites. Pertaining to school context, findings suggest that the differential social consequences of achievement experienced by African Americans are greatest in more highly achieving schools, but only when these schools have a smaller percentage of Black students. Students from Mexican descent also showed differential social costs with achievement in particular contexts. The implications of these findings to theory, policy, and future research are discussed.     

Conclusion

This special issue interrogates the contexts in which reforms are developed as well as the contexts to which they spread in order to understand the factors that influence the potential for reforms to be scaled up. Four articles from around the world address this understudied role of context. In our analysis of these articles, we take an ecological view, one that encompasses each of these challenges to explore the interplay between educators’ experiences, beliefs, and their contexts regarding reform. We begin to elaborate a theory of scale derived from medical research that develops a seed and soil application to educational research. In this theory, we describe how a discrete focus on the content of reform is no longer adequate; rather, an approach that also addresses the context and whether and to what extent it is supportive of change must also be considered. The features of supportive contexts are enumerated, including size, locus of control, norms, sociocultural context, and socioeconomic context. Three reforms are analyzed using these features as a framework. We conclude that the extent to which these conditions are prevalent may point to the capacity of a system to support a new reform.     

Retrieval practice after multiple context changes,but not long retention intervals,reduces the impact of a final context change on instrumental behavior

Recent evidence from this laboratory suggests that a context switch after operant learning consistently results in a decrement in responding. One way to reduce this decrement is to train the response in multiple contexts. One interpretation of this result, rooted in stimulus sampling theory, is that conditioning of a greater number of common stimulus elements arising from more contexts causes better generalization to new contexts. An alternative explanation is that each change of context causes more effortful retrieval, and practice involving effortful retrieval results in learning that is better able to transfer to new situations. The current experiments were designed to differentiate between these two explanations for the first time in an animal learning and memory task. Experiment 1 demonstrated that the detrimental impact of a context change on an instrumental nose-poking response can be reduced by training the response in multiple contexts. Experiment 2 then found that a training procedure which inserted extended retention intervals between successive training sessions did not reduce the detrimental impact of a final context change. This occurred even though the inserted retention intervals had a detrimental impact on responding (and, thus, presumably retrieval) similar to the effect that context switches had in Experiment 1. Together, the results suggest that effortful retrieval practice may not be sufficient to reduce the negative impact of a context change on instrumental behavior. A common elements explanation which supposes that physical and temporal contextual cues do not overlap may account for the findings more readily.     

Standardised module evaluation surveys in UK higher education: Establishing students’ perspectives

Standardised module evaluation surveys have recently been implemented or extensively redesigned at many different HEIs across the UK in response to an evolving national context, notwithstanding a body of scholarship that has called student evaluation of teaching (SET) into question. Through a focussed single-institution study, this mixed-methods research fills a notable gap in the current literature in establishing students’ perspectives on standardised module evaluation by means of a paper-based questionnaire. Its participants (N=40) recognised some general advantages of a university-wide system, such as facilitating comparison between different modules; but they also acknowledged several shortcomings relating to its lack of sensitivity to individual module contexts and schedules, yielding the overall view that standardised surveys are only partially effective as a means of teaching evaluation. The conclusion considers the wider implications of these distinctive findings, and suggests that the perceived limitations of SET point to the need to triangulate its results with data obtained through alternative evaluation mechanisms.     

The context dependence of physics identity: Examining the role of performance/competence,recognition, interest,and sense of belonging for lower and upper female physics undergraduates

While there is a growing body of work that examines disciplinary identity development, unlike qualitative work in this area, quantitative research has not fully incorporated the importance of different contexts, nor has it uniquely focused on underrepresented groups (in this case, women in physics). This study examines how the constructs posited by prior work as important for physics identity, as well as an additional theorized construct, may interrelate and affect female students' physics identity differently depending on the context. Context in this study refers to two different experiential levels in college. The constructs examined include performance/competence, recognition, and interest, as well as sense of belonging. In particular, we used structural equation modeling to examine the effect that these constructs have on the physics identity of two groups of female physics undergraduates: first year students and senior year students. The results reveal that the relationship of the theorized constructs with physics identity vary between the two groups as well as compared to prior research with broad college student populations (not just physics majors). Unlike broad college student populations, for our sample of female physics undergraduates, interest did not have a direct effect on physics identity while sense of belonging was significant only for senior year students. These results exemplify the importance of examining context or different types of student experiences when studying disciplinary identity development rather than generalizing previous frameworks to all contexts.     

The impact of social style upon person perception in primary relationships

The concept of social style, or the observable style of communication behavior exhibited by each individual, was introduced. Two primary dimensions of communication behavior were identified: assertiveness and responsiveness. Combinations of high and low levels of each dimension yield four styles: expressive, driving, amiable, and analytical. Hypotheses were presented which suggest that the consequences of social style include varying person perceptions. These perceptions included versatility, trust, credibility, power, attraction, and similarity. Finally, it was suggested that style is stable for an individual across situations and contexts. Two hypotheses were derived in order to test the relationships between social style and person perception and a research question was posed in regard to the assumption of stability. One hundred sixty‐two people had acquaintances, friends, and co‐workers fill out the research instrument. The total N for the study was approximately 375. Results indicated that in those cases where measurement met a priori standards, hypotheses were supported. The only exception was that style did not result in differences in perceptions of the composure dimension of credibility. The notion of stability was also supported by the data.     

The Impact of Context on the Development of Aggressive Behavior in Special Elementary School Children

The role of context in the development of child aggression was studied. The effects of peer aggregation and group composition on aggression development in intervention contexts and classroom contexts were compared using 71 elementary school children. We hypothesized that, due to peer group effects, group-trained children would benefit less from a social skills intervention program than individually trained children. We further hypothesized that children who transferred from special to regular education would show a change toward less aggression. This was hypothesized because of the relatively fewer accounts of negative peer-group effects in regular education. The results show that the social skills intervention program did not have differential effects for group-trained versus individually trained children. However, a change toward less aggression was found in children who transferred from special to regular education. We suggest that interventions toward decreasing child aggression might be more fruitful if the social context in which the children operate daily is considered.     

The differential influence of instructional context on the academic engagement of students with behavior problems

The teacher–student interactions of 39 students exhibiting high externalizing behavior problems and 59 students exhibiting average behavioral adjustment from urban elementary schools were directly observed. Comparisons between these students within four different instructional contexts indicated that levels of student engagement were significantly related to both behavior and classroom context. Although teachers’ use of behavioral management strategies was minimal, it was significantly related to the type of instructional context in which it occurred. Findings are discussed in terms of how different instructional contexts place unique demands and offer distinct affordances for students with behavior problems. A more comprehensive understanding of the influence of these environmental contexts can allow teachers to scaffold task demands to bring them within the domains of the student's ability.     

Contextual Variation and Memory Retrieval at Six Months

In 2 experiments we asked whether training in multiple contexts could eliminate context-dependent memory retrieval at 6 months as it does for adults. We found that 24-hour retention was disrupted when infants were trained in one context and tested in another but not when they were trained in multiple contexts prior to testing in a novel context (Experiment 1). After a long delay, however, training in multiple contexts did not facilitate memory retrieval in a novel context: An otherwise effective retrieval cue (the training mobile) did not alleviate forgetting 3 weeks later when it was presented in a novel context (Experiment 2). These findings demonstrate that multiple learning contexts can override the debilitating effects of an altered context on memory retrieval at 6 months, but only over the short term. The resistance of older memories to retrieval in novel contexts after long periods of disuse may be adaptive, insuring that potentially inappropriate or irrelevant memories will not be expressed.     

Free-Time Activities in Middle Childhood: Links with Adjustment in Early Adolescence

This study assessed links between free-time activities in middle childhood (hobbies, sports, toys and games, outdoor play, reading, television viewing, and hanging out) and school grades, conduct, and depression symptoms both concurrently and 2 years later, in early adolescence. It also explored two mechanisms that might underlie activity-adjustment links: whether the social contexts of children's activities mediate these links, child effects explain these connections, or both. Participants were 198 children (M = 10.9 years, SD = .54 years) in Year 1, and their parents. In home interviews in Years 1 and 3 of the study, mothers rated children's conduct problems, children reported on their depression symptoms, and information was collected on school grades from report cards. In seven evening phone interviews, children reported on the time they spent in free-time activities during the day of the call and their companions in each activity. Links were found between the nature of children's free-time activities and their adjustment. The social contexts of free-time activities explained activity-adjustment links to a limited degree; with respect to child effects, evidence also suggested that better adjusted children became more involved in adaptive activities over time.     

PREDICTING SUCCESS IN EARLY CHILDHOOD TEACHER EDUCATION PROGRAMS

The purpose of this study was to investigate the usefulness of standardized tests (ACT, Preprofessional Skills Test) as predictors of student success in early childhood studies. Success was measured as grade point average at the time of graduation. The sample consisted of students enrolled at a four‐year public institution in the United States (N = 129). Data analysis indicated the standardized measures, including ACT and the Preprofessional Skills Test, were significantly related to success in early childhood studies. In addition, both tests, along with high school rank and student age, were useful in the prediction of grade point average at graduation, but did little to predict success during the student teaching experience.     

Initial teacher education: a study of the efficacy of computer mediated courseware delivery in a partnership context

The null hypotheses tested were (1) that the efficacy of computer-mediated delivery of courseware was not significantly different from that of traditional university delivery methods, and (2) that the efficacy of learning in partnership with schools was not significantly different from university-based learning.
Forty three student teachers of science were assigned to four treatment groups, in a true experimental research design. The same courseware, designed to develop lesson planning skills, was delivered to the four groups. The first group (n = 11) were taught at university, receiving a traditional lecture, supplemented with a seminar. The second group (n = 12) were taught in a partnership context, receiving the traditional lecture at university, supplemented with a courseware package completed with the student's supervising teacher in school. For groups three (n = 10) and four (n = 10), the contexts were the same as for groups one and two respectively, but courseware delivery was via the Internet with e-mail tutorial support provided by the university lecturer.
Students' achievement was pre-tested and post-tested. Post-test scores were subjected to a two-way analysis of co-variance, with the delivery strategy (traditional or computer-mediated) and the context (university-based or partnership) as factors and the pre-test scores as co-variate.
Achievement gains were 12% higher when student teachers worked in a partnership context rather than entirely at university. Achievement gains were 15% higher for computer-mediated delivery when compared with traditional delivery methods. When these two factors were combined achievement gains were 36% higher.     

Pavlovian conditioning in multiple contexts: Competition between contexts for comparator status

Water-deprived rats were used to investigate the effects of training a CS in more than one context on conditioned lick suppression. In each experiment, partial reinforcement of the CS was intermingled with unsignaled presentations of the US. In Experiment 1, subjects were either trained in one context alone, trained consecutively in two contexts (such that all training in one context occurred prior to any training in the second context), or trained alternately in two contexts. Following training, the first context, the second context, or neither context was extinguished. Testing of the CS occurred in a third (neutral) context. To the extent that either training context became established as a comparator stimulus for the CS, the comparator hypothesis (Miller & Matzel, 1988) predicts an increase in excitatory responding to the CS following extinction of that context. Subjects trained in a single context exhibited appreciable fear of the CS only when the CS’s training context had been extinguished. Additionally, subjects trained consecutively in the two contexts showed increased fear of the CS following extinction of the second, but not the first training context (i.e., a recency effect). Subjects trained alternately in the two contexts showed no increased fear of the CS as a result of either context alone being extinguished. In Experiment 2, subjects trained alternately in two contexts showed increased fear of the CS only when both training contexts were extinguished, suggesting that both training contexts had become comparator stimuli. These data indicate that multiple training contexts can either compete or act synergistic-ally in modulating responding to a Pavlovian trained CS as a function of the order of training in the different contexts.
