The effect of type of reinforcer and reinforcement schedule on performances of EMR students on four selected subtests of the WISC-R

An experimental study was undertaken with 120 EMR students to examine the effect on performance of three types of test item response reinforcers (token, verbal praise, verbal neutral), and two levels of reinforcement schedule (fixed and continuous ratio). Results indicated: (a) no interaction between type of reinforcement and schedule, (b) no main effect for type of schedule, (c) but a statistically significant positive effect on scaled scores for token and verbal praise reinforcers on the Arithmetic, Digit Span, and Picture Completion WISC-R subtests. No effect on Block Design scores was noted.     

Visual guidance during competition performance and run-through training in long jumping

To ensure precise foot placement on the take-off board, long jumpers visually regulate their stride pattern during their run-up. A relationship between how much visual guidance they use and the horizontal distance they jump has not, however, been quantified. Run-up precision is often practiced using run-throughs, which exclude the take-off and, therefore, the high physical stress of the complete long jump. The validity with which this common training method simulates the long jump approach remains, however, to be verified. Four state-standard long jumpers and two heptathletes completed two sessions, each comprising six runthroughs and six competition long jumps. A 50 Hz video camera was manually panned from an elevated platform to film each trial, to enable subsequent gait characteristic evaluations. Linear regression analyses identified that a longer visual regulation phase, measured in time, distance or number of strides, was a key predictor of long jump distance. The number of strides that were visually regulated during the long jump approach was, accordingly, positively correlated with long jump distance (r = 0.67, p = 0.001). The amount of visual regulation used during run-throughs was, however, less than half (p = 0.001) of that observed during long jump approaches. Our results should compel long jump coaches to supplement run-through training with additional visual guidance exercises, to encourage their athletes to visually regulate more of their long jump approach.     

The Impact of Gender,Accommodations, and Disability on the Academic Performance of Canadian University Students with LD and/or ADHD

Academic accommodations for students experiencing disabilities are increasingly available at postsecondary institutions. More studies of the efficacy of accommodations for student success are warranted, however. Given the increased gender gap in university participation, more focus on the unique impact of gender is also needed. Using a sample of students registered with Access and Inclusion Services with learning disabilities (LD), attention-deficit/hyperactivity disorder (ADHD), and combined LD/ADHD at a Canadian undergraduate university (N = 661), we explored the impact of gender on academic performance and accommodation usage. Next, we examined how gender intersected with the impact of academic accommodations on academic performance. Women, on average, demonstrated better academic performance. Academic strategies and assistive technologies were not associated with higher academic performance. However, testing accommodations (extended time and environmental accommodations) were positively associated with academic performance for men with LD or ADHD, but not for the combined group LD/ADHD. For the former two, the more tests accommodated, the higher the academic performance. Furthermore, this gender association was most prominent for students experiencing ADHD. Interpretations and policy recommendations related to these findings are presented.     

Web‐Based Project and Key Skills Work

Pupils in England and Wales are increasingly being asked to undertake investigative‐type work, be it the new compulsory projects in data handling for GCSE Mathematics (age 14–16) (see Browne 2002 ) or the Key Skills topic application of number. This article shows how teachers can generate realistic project scenarios using real data and produce indicative model solutions from the same data. The projects range from simple presentational problems for data, through hypothesis testing to complex modelling scenarios.     

Investigation of Clinically Significant Change by Severity Level in College Counseling Center Clients

The authors investigated the number of sessions necessary for college counseling center clients of different levels of severity of distress at intake to achieve clinically significant change (CS) in therapy. The Outcome Questionnaire‐45 (M. J. Lambert, N. B. Hansen, et al., 1996) was used to categorize 914 clients by severity of distress. Analyses of outcome indicated that clients with less and more severe distress needed 14 and 20 sessions, respectively, for 50% in each group to achieve CS. Implications are discussed.
