The impact of an intensive multisensory reading program on a population of learning-disabled delinquents

The high prevalence of learning disabilities in the juvenile delinquent population has been well documented, but attempts to remediate and have an impact on recidivism of this population of delinquents has produced limited results. The present study is a replication of the remediation phase of the 1976 LD/JD Project with methodological refinements to control for treatment integrity and strength of treatment. Delinquents in two detention facilities were screened for a developmental reading disorder. Subjects were selected for the study based on normal intelligence, full English proficiency, and a discrepancy of 15 points between reading achievement and IQ. Subjects in the treatment group received 90 minutes of remedial reading instruction per day using a multisensory (Orton/Gillingham) approach. A comparison group received 45 minutes of daily reading instruction in the regular classroom. There was no significant difference between the two groups in mean age of first arrest, mean age, and mean hours of reading instruction. Based on pre- and posttesting in reading and arrest records one year following release, the treatment group made significantly greater growth in reading (.33 year growth vs −.05 year growth per 10 hours of instruction) and had a significantly lower rate of recidivism (41 percent vs 63 percent) than the comparison group. Results were discussed in terms of hours of instruction necessary to improve reading, intervening treatment variables, and cost effectiveness of remedial program.

Perceived interplay between flexible learning spaces and teaching,learning and student wellbeing

In recognition of the evolving learning needs of twenty-first century school students, changes to teaching practices and the incorporation of technology are increasingly accompanied by modifications to the built classroom environment. Typically rows of desk and chairs are replaced with a range of furniture that can be configured in various ways to facilitate teaching and learning. This article explores the perceived relationship between these flexible learning spaces and teaching, learning and wellbeing outcomes. The perceptions and experiences of 12 school principals, 35 teachers and 85 students from four primary and four secondary schools in Australia were examined. Flexible learning spaces were reported to facilitate student-centred pedagogy and selfregulation, collaboration, and student autonomy and engagement. Modified spaces were reportedly more enjoyable, comfortable and inclusive and allowed greater interaction. The findings are discussed in light of Beaton’s five key design principles of student-centred learning environments to explore the connection between the physical classroom environment and teaching and learning. Self-Determination Theory is used to interpret how elements of the physical space facilitate the creation of a social environment that encourages greater motivation to learn and increases student wellbeing. The research contributes to an understanding of how flexible learning spaces are used and with what effect, thereby addressing a present gap in the literature.     

Evaluation of Self by Young People with Down Syndrome

There have been relatively few studies of self-esteem with young people with moderate and severe intellectual disability. One reason for this is likely to be measurement difficulties. The purpose of the present study was to assess the usefulness of three measures of self-esteem in 72 young people with Down syndrome aged from 17 to 24 years. Forty-five young people, mean VMA 5 years 10 months, were assessed on the Pictorial Scale of Perceived Competence and Social Acceptance for Young Children and the Joseph PreSchool and Primary Self-Concept Screening Test. Nineteen young people, mean VMA 8 years 9 months, completed the Self-Perception Profile for Learning Disabled Students. Validity was assessed by reading scores and by interviews with the young people and their parents. Eight young people with the most severe intellectual disability could not do any test; the remainder were able to respond to the format of the appropriate tests. On all measures they rated themselves positively. Internal consistency estimates were high, but validity was only demonstrated for the Self-Perception Profile for Learning Disabled Students, supporting its use with the young people who had VMAs of around 7 years. Evaluation of self also showed a standard developmental trend.     

Using the standard Wald confidence interval for a population proportion hypothesis test is a common mistake

Employing a Wald confidence interval to test hypotheses about population proportions could lead to an increase in Type I or Type II errors unless the hypothesized value, p0, is used in computing its standard error rather than the sample proportion.     

Beginning student teachers' opinions about teaching primary science

Conclusions Beginning student teachers have already acquired very definite views about teaching science before they begin their teacher training course. These views are generally similar to the views espoused by science educators, but are contrary to the classroom practices of many teachers. Their views seem to have origins in what the students perceive to have been meaningful and enjoyable learning experiences for themselves in their own schooling; and to a lesser extent for children they have observed. Female students who have studied more science at high school tend to favour the use of worksheets in experimental work. Several interesting questions arise from these findings: When these students begin to teach as qualified teachers, will they still espouse the same opinions? If so, does that mean that there is a ‘new wave’ of teachers entering the service who are more committed to hands-on activity work than their older colleagues? If not, what aspects of the teacher training process have caused them to change their opinions? Will these present students be using hands-on strategies themselves after they have been teaching for some time? That is, do system and school constraints effectively prevent teachers from using such strategies? Can secondary science teachers do more to influence positively their students' opinions about teaching science, such as engendering more positive attitudes to science, incorporating more hands-on work, and relying less on printed worksheets in laboratory work? This exploratory work has highlighted the concern expressed by Morrissey (1981) in that there is a great need for long term longitudinal studies of student teachers' attitudes to teaching science, with a particular focus on their teaching behaviours after graduation.     

Students using posters as a means of communication and assessment

Poster sessions are widely used as a medium for the communication of results by professionals at conferences and by students to their peers. The authors have introduced poster sessions into undergraduate mathematical modelling courses. This has given our students an interesting and challenging task and it has caused us to devise a scheme for the assessment of posters.This paper surveys the use of poster sessions with undergraduates, outlines the rationale for using posters with mathematics students, describes our experiences and proposes criteria to use in the assessment of student posters.     

Blocking in landmark-based search in honeybees

Two experiments tested blocking in landmark-based search in honeybees. Honeybees in the experimental group were trained in Phase 1 with a single landmark in a constant spatial relation to the target (sugar water). In the compound training second phase, the landmark used in Phase 1 (blocking landmark) and a new landmark (blocked landmark) were presented at constant spatial relations to the target. The blocking and blocked landmarks differed from each other in color and position, and the blocking landmark retained the same spatial relationship to the target as in Phase 1. In Experiment 1, the control group experienced only Phase 2 training with two landmarks. In Experiment 2, the control group was trained with a different landmark in a different position in Phase 1. Blocking was found in both cases.
