Item difficulty in the evaluation of computer-based instruction: an example from neuroanatomy     

Chariker JH  Naaz F  Pani JR 《Anatomical sciences education》2012,5(2):63-75

This article reports large item effects in a study of computer-based learning of neuroanatomy. Outcome measures of the efficiency of learning, transfer of learning, and generalization of knowledge diverged by a wide margin across test items, with certain sets of items emerging as particularly difficult to master. In addition, the outcomes of comparisons between instructional methods changed with the difficulty of the items to be learned. More challenging items better differentiated between instructional methods. This set of results is important for two reasons. First, it suggests that instruction may be more efficient if sets of consistently difficult items are the targets of instructional methods particularly suited to them. Second, there is wide variation in the published literature regarding the outcomes of empirical evaluations of computer-based instruction. As a consequence, many questions arise as to the factors that may affect such evaluations. The present article demonstrates that the level of challenge in the material that is presented to learners is an important factor to consider in the evaluation of a computer-based instructional system.  相似文献   

Correlates of problem recognition and intentions to change among caregivers of abused and neglected children     

Littell JH  Girvin H 《Child abuse & neglect》2006,30(12):1381-1399

OBJECTIVE: To identify individual, family, and caseworker characteristics associated with problem recognition (PR) and intentions to change (ITC) in a sample of caregivers who received in-home child welfare services following substantiated reports of child abuse or neglect. METHODS: Caregivers were interviewed at 4 weeks, 16 weeks, and 1 year after referral for in-home services. In these interviews, the University of Rhode Island Change Assessment scale assessed PR and ITC in relation to caregiving practices. Additional data were obtained from administrative records and surveys of in-home services caseworkers. We used growth models to identify caregiver, family, and caseworker characteristics associated with initial levels of PR and ITC, and with changes in PR and ITC over time. RESULTS: Contrary to expectations, there were no overall increases in PR and ITC during the first 4 months of in-home services. PR and ITC scores fluctuated over time, in relation to some external events, case characteristics, and caseworker characteristics; however, we were able to account for small portions of the variance in PR and ITC. Controlling for social desirability bias and other variables in the analysis, negative life events, lack of network support, and the severity of caregiver depression were associated with greater PR; housing problems were associated with lower PR. Caregiver depression and age were associated with ITC. Caregivers whose children had been removed from their homes showed significant increases in ITC in the first few months of in-home services. The duration of caseworkers' child welfare experience predicted increases in their clients' PR in the first 4 months and more frequent contacts with an experienced caseworker predicted small, but significant increases in ITC over time. CONCLUSIONS: PR and ITC are associated with somewhat different case characteristics and may be affected by caseworkers' experience.  相似文献   

Children and Place: Stories We Have, Stories We Need     

Julia Ellis 《Interchange》1999,30(2):171-190

Given existing curricula, instructional and assessment practices, teacher preparation programs, and multicultural education approaches, schools can be unhelpful places for students who are not at least middle class and politically white. Critical theory offers a range of conceptual frameworks for understanding and addressing these injustices but teachers find the ideas difficult to learn or to practice in classrooms. Increased attention to the use of stories is suggested to support individual and collective transformation and growth for teachers, students, and communities.  相似文献

How Adults’ Actions,Outcomes, and Testimony Affect Preschoolers’ Persistence     

Julia A. Leonard  Andrea Garcia  Laura E. Schulz 《Child development》2020,91(4):1254-1271

Across four experiments, we looked at how 4- and 5-year-olds' (n = 520) task persistence was affected by observations of adult actions (high or low effort), outcomes (success or failure), and testimony (setting expectations—“This will be hard,” pep talks—“You can do this,” value statements—“Trying hard is important,” and baseline). Across experiments, outcomes had the biggest impact: preschoolers consistently tried harder after seeing the adult succeed than fail. Additionally, adult effort affected children’s persistence, but only when the adult succeeded. Finally, children’s persistence was highest when the adult both succeeded and practiced what she preached: exerting effort while testifying to its value.  相似文献

Adapting an anti-bullying programme for UK special schools     

Julia R. Badger  Lucy Bowes  Christina Salmivalli  Richard P. Hastings 《Support for Learning》2023,38(4):178-182

Bullying is a public health priority but to date, there is a lack of evidence-based anti-bullying programmes or interventions designed for use in special schools. KiVa is a successful anti-bullying programme for mainstream schools currently used in 23 countries. This brief paper outlines the co-development and adaptation of two KiVa lessons into KiVa-SEND lessons and their implementation in two special schools in the UK. One school supports pupils with a primary need of Autism, the other supports pupils with severe and complex learning disabilities. Engagement with the lessons was high from both pupils and staff; the content was perceived as acceptable by staff, complementing the curriculum and perceived as suitable for their pupils. Minor adjustments need to be made to ensure all pupils can comprehend and access the concepts. Further development of the KiVa-SEND programme and testing its potential effectiveness to reduce bullying and associated negative outcomes in special schools is now warranted.

Key Points

• There is a lack of evidence-based anti-bullying programmes for use in special schools. This paper details the piloting of an adaptation of KiVa (a successful, evidence-based anti-bullying programme for mainstream schools) for use in special schools.
• The adaption (KiVa-SEND) was a co-design between a couple of special school teachers, and educational and psychological researchers to ensure the materials and approach were in line with school requirements and teaching practices.
• The KiVa-SEND lesson engagement was excellent from the 12 staff and 62 learners involved and the materials were deemed acceptable via direct feedback and researcher observations. Suggestions were provided on how to make the materials even more suitable for diverse learning needs.
• KiVa-SEND has the potential to be embedded within the special school curriculum and then be tested for its effectiveness at reducing bullying and associated negative outcomes of bullying amongst the special school population.
