Response Inhibition,Memory, and Attention in Boys with Attention-Deficit/Hyperactivity Disorder

Newly developed measures of response inhibition, verbal and non-verbal memory, and attention were applied to a sample of boys diagnosed with ADHD (n = 50; 14 predominantly inattentive type and 36 combined type) with no diagnosed comorbid conditions, who had received no stimulant medication for a minimum period of 20 hours prior to test administration. Performance was assessed relative to 50 individually age-matched control boys. Results revealed significant multivariate group differences on all three tests, supported by univariate effects on measures of verbal memory and attentional switching. In all cases, ADHD boys performed more poorly than the control boys. However, contrary to expectations, boys with ADHD made significantly fewer impulsive responses (false positives) on the specific measure of response, despite recording significantly more misses than the controls. Furthermore, no significant differences were observed according to ADHD subtype. The present research therefore demonstrates and more fully characterises the nature of the observed memory and attentional impairments in boys with ADHD and would appear to have clear implications for education and the further development of theory.     

Developing Portfolios to Evaluate Teacher Performance in Early Childhood Education

One goal of the teacher's professional portfolio is to describe the full range of abilities and document effective teaching over an extended period of time. In this article we discuss the procedure that teachers can use in developing their own portfolio assessment to help generate data for making decisions about teaching performance. The development of a teacher portfolio requires planning, time, organization and cooperation from students, colleagues, parents and supervisors. The format of the portfolio may vary from individual to individual and be based upon personal preference. Organizations and contents of the teacher portfolio are suggested. Questions and associated lists of teaching artifacts are discussed based on the authors' experiences as early childhood classroom teachers and university professors. The answers to these questions will guide the selection of activity-generated products to best represent the essence of the teacher performance.     

Colleagues’ roles in the professional development of teachers: Results from a research study of National Board certification

This study investigated the nature of interaction among teachers that occurred around the National Board certification (NBC) process and how that collegial interaction influenced teachers’ professional development. Qualitative interviews were conducted with 14 teachers who were either considering NBC, in the process, or had been awarded NBC. Interview data were analyzed using the constant comparative method. Results indicated that teacher interactions triggered by NBC helped one another's professional development in several ways: (a) enhancing reflection on teaching practice, (b) establishing a professional discourse community, (c) raising the standards for teaching performances, and (d) facilitating collaboration. Implications for teacher professional development were discussed.     

Sci-Tec: Evaluating a non-deficit model of in-service

The Sci-Tec project was based on an interactive, non-deficit model of in-service in which the fundamental principle was to value the expertise of all participants, and to encourage them to share that expertise with others. As part of the unfolding of the project, the participants also identified various areas of need as they arose, and these too became elements of the in-service agenda. The model has proved to be robust when applied in a wide range of schools, and with teachers who originally expressed widely varying degrees of confidence and interest in teaching primary science and technology. Specializations: primary science in-service education, curriculum leadership Specializations: in-service and pre-service primary science and technology     

Issues and trends in qualitative research: Potential for developing countries

This article builds upon previous work carried out by the authors in the field of comparative and international education, with special reference to the implications of globalisation and contemporary methodological trends for educational research in developing countries. Distinctions are drawn between methodology and methods in exploring the potential and limitations of qualitative strategies for researchers, policy-makers and development assistance agencies. A review of contemporary trends and developments draws attention to a related volume of new work, the value of case studies of educational practice, the importance of context and the dangers of uncritical international transfer. The article also examines linkages between post-modernism and the interpretivist paradigm, issues of data analysis and validation, and the possible benefits to be gained from practitioner research and evaluation in the process of research capacity building in developing countries.     

Meaningful actions and motivated projects in the transition to adulthood: two case illustrations

A framework for understanding career transitions based on the joint processes and goals of those engaged in the transition and significant others in the person’s social network was used to study the transition to adulthood of youth aged 17–19 years and their families. Twenty parent-youth dyads participated in this study in which a transition project was identified and monitored for 6 months. Two cases are used to illustrate the characteristics of the motivated transition project at the levels of meaning, functional processes, and conscious and unconscious behaviour and structural support and resources.     

Helping students understand their learning styles: Effects on study self‐efficacy,preference for group work,and group climate

Small tutorial groups in higher education are often composed without regard to students’ gender or broad knowledge background, for example, yet research indicates that composing groups on the basis of gender and prior qualifications may have significant effects on assessment outcomes. Previous studies have also investigated the effects of composing groups on the basis of learning style preference and found no effects. The effect of combining group composition with training in learning styles is unclear, however. In this study we report on the effects of workshop training in learning styles on balanced group members’ study self‐efficacy, preference for group work, group climate, and assessment performance. Although we found no effects, students reported greater self‐awareness of their own learning and acceptance of others’ styles. We conclude that in collaborative learning environments, training may need to go beyond facilitating growth in students’ self‐awareness to include a focus on how to apply this understanding to improving group function and helping others to learn.     

Faculty at work: Focus on research,scholarship, and service

Within the framework of cognitive motivation theory, selected personal and environmental motivational variables for faculty in eight liberal arts and science departments from community colleges, liberal arts colleges, comprehensive colleges and universities, and research universities were regressed against faculty allocation of work effort given to research, scholarship, and service. The data came from a 1988 national survey of faculty.Gender, (sociodemographic), quality of graduate school attended, career age, andrank (career); self-competence andself-efficacy regarding research, scholarship, and service andpercent time prefer to give to research, scholarship, and service (self-valuations); andinstitutional preference, consensus andsupport, andcolleague commitment to research, scholarship, and service (perception of the environment) were entered into regressions.R ²s were generally strong (.64 for liberal arts-I institutions) and significant. For all institutional types,self-valuation (self-competence and-efficacy) motivators significantly accounted for the explained variance.Sociodemographic andcareer variables did not explain appreciable amounts of variance.     

Effective compiler error message enhancement for novice programming students

Programming is an essential skill that many computing students are expected to master. However, programming can be difficult to learn. Successfully interpreting compiler error messages (CEMs) is crucial for correcting errors and progressing toward success in programming. Yet these messages are often difficult to understand and pose a barrier to progress for many novices, with struggling students often exhibiting high frequencies of errors, particularly repeated errors. This paper presents a control/intervention study on the effectiveness of enhancing Java CEMs. Results show that the intervention group experienced reductions in the number of overall errors, errors per student, and several repeated error metrics. These results are important as the effectiveness of CEM enhancement has been recently debated. Further, generalizing these results should be possible at least in part, as the control group is shown to be comparable to those in several studies using Java and other languages.
