Challenging behaviour: the perceptions of teachers of children and young people with severe learning disabilities     

Dawn Male 《Journal of Research in Special Educational Needs》2003,3(3):162-171

This paper reports the findings of a study which aimed to elicit teachers' perceptions of pupils' challenging behaviour. Teachers were asked to indicate: which aspects of challenging behaviour concerned them; their responses to it; which strategies they found effective; what they believed to be the causes of it; how stressed they felt; and how effective they felt when dealing with it. They were also asked to identify sources of information, advice and help and to rate different types of challenging behaviour in terms of severity of challenge. Results indicate that teachers are concerned about challenging behaviour and find it stressful. Whilst considering themselves to be effective in dealing with it, a proportion report feeling frustrated by it, angry, upset and/or at a loss. The most frequently cited challenging behaviour was aggression, although self-injury was found to be the most challenging. Whilst recognising the communicative basis of many forms of challenging behaviour teachers nevertheless tended to select strategies which were concerned with diffusion rather than prevention. The most likely source of information, advice and help was other teachers. Some differences in responses were noted according to experience and whether or not additional qualifications were held.  相似文献   

Brain mechanisms for changes in processing of conditioned stimuli in Pavlovian conditioning: Implications for behavior theory     

Peter C. Holland 《Learning & behavior》1997,25(4):373-399

This article is a review of the results of a series of experiments designed to identify brain systems involved in appetitive conditioning of rats. It discusses some of their implications for behavioral theories of learning, especially those that concern changes in processing of conditioned stimuli (CSs). Evidence is presented which suggests that separable brain circuits are involved in (1) the production of CS-dependent conditioned orienting responses, (2) the enhancement of CS associability produced when expectancies about upcoming events are violated, (3) the reduction of CS associability produced when stimuli are consistent predictors of other events or are presented without consequence, and (4) the abilities of CSs to serve as reinforcers for second-order conditioning and to be sensitive to postconditioning changes in the value of the unconditioned stimulus (US). Finally, none of these circuits seems critical for normal acquisition of the most common indicator of Pavlovian conditioning, US-dependent conditioned responses (CRs). Although the independence of brain pathways does not demand independence of behavioral function, clustering of behavioral phenomena on anatomical grounds may provide useful guides for constructing behavior theories.  相似文献   

Determinants of Disciplinary Practices in Low-Income Black Mothers   总被引：5，自引：0，他引：5  

Michelle L. Kelley  Thomas G. Power  Dawn D. Wimbush 《Child development》1992,63(3):573-582

Disciplinary attitudes and practices of low-income black mothers were examined. Mothers were interviewed about their parenting attitudes and control practices, and their responses were coded in terms of the degree to which they took a parent- versus a child-oriented approach to discipline. Mothers in the sample varied widely in their attitudes toward physical punishment, and mothers who used power-assertive techniques were as likely to take the child's perspective and give input into the socialization process as those who did not. Factors associated with maternal disciplinary styles included: maternal education, father absence, maternal age, and self-reported religious beliefs. Findings are discussed in terms of the variability in disciplinary practices in this population, as well as the factors contributing to these individual differences.  相似文献   

Using rapid application development to improve the usability of a preservice teacher technology course

The aim of this research was to examine the use of a rapid application development (RAD) approach in improving the usability (effectiveness, efficiency, and appeal) of instructional materials for preservice teachers. The RAD approach used was the analysis, synthesis, evaluation and change (ASEC) model (Reigeluth & Nelson, 1997). After examining existing materials, 11 units of instruction were prototyped, tested, modified, and retested with the requisite changes being implemented over the course of three semesters. Qualitative and quantitative data were collected from 570 students, 7 instructional designers, and 4 lab assistants. Results of the study showed significant increases in usability scores between the second and third semester. Both positive and negative experiences in using a rapid development model are discussed.  相似文献

Savings test for associations between neutral stimuli     

Peter C. Holland  Robert T. Ross 《Learning & behavior》1983,11(1):83-90

Three experiments showed a savings procedure to be an effective and sensitive alternative to sensory preconditioning procedures as a measure of associations among neutral stimuli. Experiment 1 showed that within-compound associations developed more rapidly in reinforced appetitive serial compound conditioning when nonreinforced preexposure to the serial compound was given than when separate element or no preexposure was given. Experiment 2 showed the savings effect to be highly stimulus specific. Experiment 3 examined the facilitation of serial compound conditioning after either simultaneous or serial nonreinforced preexposure to the elements of the compound. The results of that experiment were consistent with those of analogous sensory preconditioning experiments. When preexposure involved only the two elements of the subsequently reinforced compound, serial preexposure produced more savings than simultaneous preexposure. But when preexposure involved a three-stimulus procedure like that used by Rescorla (1980b), simultaneous preexposure resulted in more savings. Advantages of the savings procedure over sensory preconditioning as a measure of association among neutral stimuli are discussed.  相似文献   

Feature extinction enhances transfer of occasion setting     

Peter C. Holland 《Learning & behavior》1989,17(3):269-279

In three experiments, transfer effects in appetitive serial feature-positive discrimination procedures (X→A+,A?) were examined with rat subjects. Nonreinforced presentations of the feature (X) alone had little or no effect on that cue’s ability to modulate responding to the target cue with which it had originally been trained (A) but enhanced its ability to modulate responding to another cue (B), which had been the target within another serial feature-positive discrimination (Y→B+,B?). These effects were observed when the nonreinforcedX presentations occurred either concurrently withX→A+,A? training or afterward. Regardless of whether or not nonreinforcedX presentations were administered,X did not modulate responding evoked by a cue that had not been trained within a serial feature-positive discrimination. These data help resolve conflicts in published reports of transfer or its absence in this conditioning situation, and shed light on the nature of the modulatory or occasion-setting powers of feature cues in serial feature-positive discrimination learning.  相似文献   

An Australian study of possible selves perceived by undergraduate engineering students     

Dawn Bennett  Sally A. Male 《European Journal of Engineering Education》2017,42(6):603-617

In this study, we worked with second-year engineering students at an Australian university to examine previously identified threshold concepts within the theoretical framework of Possible Selves. Using workshops as the context for intensive work with students, students were encouraged to consider their future lives and work, including their engineering fears, expectations, and aspirations. The findings revealed many students to have a poor understanding of the realities of engineering work. Moreover, perceived gaps between self-efficacy and the requirements of engineering work appeared to be motivating if students deemed it possible to reduce the gap, but demotivating if they identified a characteristic over which there was perceived to be no control. The study suggests that these engineering students needed more opportunities to explore both the roles of engineers and their own possible selves. Overall, the findings indicate that higher education students may need encouragement and support to explore potential future roles, and they strengthen calls for further research in this area.  相似文献   

Positive Youth Development Among Diverse Racial–Ethnic Children: Quality Afterschool Contexts as Developmental Assets          下载免费PDF全文

Emilie Phillips Smith  Dawn P. Witherspoon  D. Wayne Osgood 《Child development》2017,88(4):1063-1078

Positive youth development (PYD) deserves more empirical attention, particularly among children of diverse racial–ethnic backgrounds. Given the need among families for monitoring and supervision during out‐of‐school time, community‐based afterschool is a potentially promotive ecological setting. This study explores the quality of afterschool experiences upon PYD. This multimethod study includes over 500 elementary school children in Grades 2–5 (M_age = 8.80, SD = 1.12). The sample comprises of 49% White, 27% African American, 7% Latino, and 17% mixed race/others with 45% free/reduced lunch eligible children. In multilevel models, independently observed quality across time positively impacted competence, connection, caring for all youth, and cultural values for racial–ethnic minority youth. Afterschool fosters PYD, including sociocultural dimensions, when comprised of appropriately structured, supportive, and engaging interactions.  相似文献
