A meta-analysis of maturation-related variation in adolescent boy athletes’ adaptations to short-term resistance training

This meta-analysis investigated the maturation-related pattern of adaptations to resistance training in boy athletes. We included studies examining the effects of 4–16-week resistance training programmes in healthy boy athletes aged 10–18 years. Pooled estimates of effect size for change in strength across all studies (n = 19) were calculated using the inverse–variance random effects model for meta-analyses. Estimates were also calculated for groups based on likely biological maturity status (“before”, “during” and “after” peak height velocity). Using the standardised mean difference, resistance training increased strength across all groups (effect size = 0.98, [CI: 0.70–1.27]). Strength gains were larger during (1.11 [0.67–1.54]) and after (1.01 [0.56–1.46]) peak height velocity than before (0.5 [?0.06–1.07]). Adaptations to resistance training are greater in adolescent boys during or after peak height velocity. These findings should help coaches to optimise the timing of training programmes that are designed to improve strength in boy athletes.     

Psychodrama and sociodrama in primary and secondary education

Students need practice in decision making and problem solving, and sociodrama can provide this practice in a safe, nonthreatening context. It helps them to become aware of the typical ways they solve problems, and it increases both social and personal awareness. It may promote acceptance, cooperation, and cohesiveness in the classroom. Students readily adapt to this kind of activity and find it both enjoyable and stimulating. It is recommended as a useful method in the classroom and guidance and counseling setting for helping students understand their own behavior and the behavior of others.     

Factor analysis of the abbreviated conners teacher rating scale: Implications for the assessment of hyperactivity

A factor analysis of the abbreviated Conners Teacher Rating Scale (CTRS) was completed using a sample of 108 regular and special education students. Two factors accounted for 69.5% of the total response variance: Factor I consisted of items describing attention deficits and motor activity, and Factor II consisted of items describing excessive affective reactions. It is suggested that the abbreviated CTRS be interpreted with respect to its latent structure, rather than to one global score as has been common practice.     

Teachers' instruction of noncategorically grouped handicapped children

Abstract

The sample for this study consisted of 46 noncategorically identified handicapped students who had been assigned to functionally grouped self‐contained classes. For purposes of this research, only a child study team reevaluated the students and supplied a label, learning disabled or emotionally disturbed. We observed all students on at least nine occasions on three behaviors: teachers' academic questions directed toward them, extended feedback from teachers, and dyadic work interactions. Although the special education classroom teachers did not know the labeled identity of any student in the class, they instructed the two groups differently. They instructed the emotionally disturbed children with fewer instances of academic questioning, less extended feedback for their responses, and fewer dyadic work interactions.     

Reliability as Argument

Reliability consists of both important social and scientific values and methods for evidencing those values, though in practice methods are often conflated with the values. With the two distinctly understood, a reliability argument can be made that articulates the particular reliability values most relevant to the particular measurement situation and then the most appropriate evidence and theory to support an argument for the presence of that value. The steps in making a reliability argument are explained and an extended example is given. The article is intended to provoke discussion, debate, and the development of additional reliability methodologies.     

Considerations for the Occasional Project Manager

Performance improvement professionals who occasionally manage projects can benefit from applying the discipline of project management. This article offers a checklist of proven techniques that lend themselves to most projects. Many techniques are applicable even in organizations lacking a project management culture. These techniques do not assume formal project management training. The checklist draws on common elements identified through a review and analysis of key sources that outline the ingredients for project success, such as communication, stakeholder engagement, executive support, and risk management.     

‘It’s a life-changing point for me’: critical consciousness,collective empowerment and global awareness as activist identity change in ‘popular education’

The Youth Global Awareness Programme (YGAP) is a 2-week residential ‘popular education’ programme for young, diverse, international, labour movement activists, run by the International Federation of Workers Education Associations in Cape Town, South Africa. In this mixed method study (N = 47), we draw on the Social Identity Approach to Education and Learning. We propose that the participatory, peer-to-peer learning during YGAP leads to activist identity change, where critical consciousness, collective empowerment and global awareness develop as group norms. The first longitudinal questionnaire study found significant increases in activist identity and critical consciousness, which predicted increased collective empowerment. In the second focus group study, data were analysed with reflexive thematic analysis and two themes provide compelling evidence of learning during YGAP as identity change processes. Participants’ commonalities and differences enhanced activist identities with global awareness. Simultaneously, new knowledge, passion, hope and connection to a global activist community created collective empowerment.
