Changes in sensed dis/continuity in the development of student teachers throughout teacher education

Initiatives aimed at supporting student teachers for entering and staying in the teaching profession require a better understanding of the nature of student teachers’ development as it unfolds during teacher education. Accordingly, we focused on changes in the extent to which student teachers perceive and expect dis/continuity in their development during the programme. The design of the study included 25 authentic supervision dialogues/conversations, enabling the analysis of development within and across six student teachers’ developmental trajectories. Findings showed that student teachers’ initial sense of dis/continuity is not necessarily predictive of progress and (un)successful completion of teacher education. Furthermore, sensed dis/continuity varies differently over time in student teachers, both in terms of when it changes as well as in terms of with what types of past perceptions and future expectations these changes occur.     

‘People at the heart of our processes’, a case study of how a nursery school and children's centre promotes community cohesion

This article reports on a doctoral case study of how an English integrated nursery school and children's centre fulfils its legal duty to promote community cohesion. The provocation for the enquiry derives from the author's growing unease over the perceived limitations of a target-driven culture currently pervading English schools. A case is made for the importance of schools’ community cohesion work; presented here as a potential vehicle with which to broaden and extend the school experience beyond the narrow individualistic confines imposed by current accountability frameworks.     

Prevention of fatherhood disorders — Accompanying early father-child interaction in day-care centers

Over the last fifteen years, increasing numbers of fathers have been attending medical or day-care centers for young children, traditionally “reserved” for mothers and babies. Thus the professionals who work there are able to take an active part in the “co-construction of the fathers” by accompanying their emerging fatherhood. The Research-Action-Training approach used in partnership with the public health service (“Mother and Child Protection” in Paris) has proven to be a particularly interesting tool for modifying the routine found in day-care centers. Through the transfer of knowledge on fatherhood processes and new triadic models, it has led to improvements in the manner fathers are welcome but also babies and the whole family.     

Training self-regulated learning skills with video modeling examples: Do task-selection skills transfer?

Self-assessment and task-selection skills are crucial in self-regulated learning situations in which students can choose their own tasks. Prior research suggested that training with video modeling examples, in which another person (the model) demonstrates and explains the cyclical process of problem-solving task performance, self-assessment, and task-selection, is effective for improving adolescents’ problem-solving posttest performance after self-regulated learning. In these examples, the models used a specific task-selection algorithm in which perceived mental effort and self-assessed performance scores were combined to determine the complexity and support level of the next task, selected from a task database. In the present study we aimed to replicate prior findings and to investigate whether transfer of task-selection skills would be facilitated even more by a more general, heuristic task-selection training than the task-specific algorithm. Transfer of task-selection skills was assessed by having students select a new task in another domain for a fictitious peer student. Results showed that both heuristic and algorithmic training of self-assessment and task-selection skills improved problem-solving posttest performance after a self-regulated learning phase, as well as transfer of task-selection skills. Heuristic training was not more effective for transfer than algorithmic training. These findings show that example-based self-assessment and task-selection training can be an effective and relatively easy to implement method for improving students’ self-regulated learning outcomes. Importantly, our data suggest that the effect on task-selection skills may transfer beyond the trained tasks, although future research should establish whether this also applies when trained students perform novel tasks themselves.     

Screening the active constituents of Chinese medicinal herbs as potent inhibitors of Cdc25 tyrosine phosphatase, an activator of the mitosis-inducing p34cdc2 kinase

Objective: To screen and evaluate the active constituents of Chinese medicinal herbs as potent inhibitors of Cdc25 phosphatase. Methods: The affinity chromatography purified glutashione-S-transferase/Cdc25A phosphatase fusion protein and Cdc2/cyclin B from the extracts of starfish M phase oocytes are used as the cell cycle-specific targets for screening the antimitotic constituents. We tested 9 extracts isolated from the Chinese medicinal herbs and vegetables including the agents currently used in cancer treatment by measuring the inhibition of Cdc25A phosphatase and Cdc2 kinase activity. The antitumor activity of the extracts was also evaluated by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay and flow cytometry. Results: Cdc25A inhibitory activity and antitumor activity are detected in the extracts isolated from three Chinese medicinal herbs Agrimona pilosa; Herba solani lyrati; Galla chinesis. Conclusion: We found three extracts isolated from Chinese medicinal herbs have potential inhibitory activity of Cdc25 phosphatase using a highly specific mechanism-based screen assay for antimitotic drug discovery.     

Victimization during childhood and revictimization in dating relationships in adolescent girls

OBJECTIVE: Various experiences with violence during childhood and adolescence (parental violence, exposure to marital violence, sexual abuse within and outside the family, sexual harassment at school, community violence, involvement with violent or victimized peers, and previous dating violence) are examined as potential risk factors for psychological, physical, and sexual revictimization in adolescent girls' dating relationships. METHOD: A group of 917 teenage girls (mean age = 16.3) were recruited in 5 high schools located in low to middle socioeconomic areas. Participants were in the 10th and 11th grades, and each completed a self-administered questionnaire. Analyses were performed on the 622 participants who reported having at least one dating partner in the last 12 months. RESULTS: Prevalence rates for past victimization experiences varied from 13% to 43%. Regarding last-year dating victimization, prevalence rates varied from 25% to 37%, depending on the type of violence sustained. Results suggest that extrafamilial experiences with violence are stronger risk factors for recent dating victimization than intrafamilial experiences, especially being sexually harassed by male peers at school and being involved with violent or victimized peers during the year preceding the survey. However, it is important to differentiate between girls who are repeatedly victims of violence in a single, long-term relationship (repeat dating victimization), and girls who are revictimized by different partners (dating revictimization), the former sustaining more frequent physical and psychological violence than the latter. CONCLUSIONS: Findings underline the importance of early prevention of adolescent dating violence. Prevention programs should especially address extrafamilial experiences with violence as important risk factors for victimization in dating relationships, and teach girls strategies to break up abusive relationships.     

Cohorts and Relatedness: Self-Determination Theory as an Explanation of How Learning Communities Affect Educational Outcomes

This study examines whether feelings of relatedness constitute a substantial means by which learning communities (cohorts) improve learning outcomes in higher education. It applies Ryan and Deci’s Self-Determination Theory to an analysis of the National Survey of Student Engagement. The SDT hypothesizes that environments that support perceptions of social relatedness improve motivation, thereby positively influencing learning behavior. The authors propose that participation in cohort programs constitutes such an environment. Measuring student perceptions of the contributions of their institutions, the study found increased relatedness to peers and faculty and increased higher order thinking assignments (a control variable included in the research model) to be substantial predictors of educational outcomes relevant to literacy, critical thinking, and, especially, job preparation. The researchers suggest that institutions will want to ensure that their learning community designs enhance student feelings of relatedness.     

A distributed collaborative science learning laboratory on the internet

Abstract

A Distributed Collaborative Science Learning Laboratory (DCSLL) was designed, prototyped, and pilot‐tested as the “Electrical Circuit Simulator.” This laboratory was part of a module on electricity within an introductory distance course for postsecondary students on the scientific method. The concept of DCSLL emerged from work in distance education and new technologies, cooperative/collaborative learning, and science education. Instructional design principles derived from these areas are presented, and their implementation in the DCSLL is described, followed by results from the pilot test. Analysis of the results led to the articulation of six instructional design guidelines, identified as being key to the development of such learning environments.
