title: A Meta-Analysis of interventions to reduce disruptive behaviour in classroom settings

authors: Frame, Belinda

subjects: classroom management

abstract: I conducted a meta-analysis of 48 single-case and small-group experimental design studies from 1997 to 2024 that investigated interventions to reduce disruptive behaviour in classroom settings. I extracted data from graphs displaying behavioural data resulting from interventions to reduce disruptive behaviour and then I calculated Tau-U effect sizes. A total of 180 effect sizes from the 48 studies produced a total mean effect size of -0.82 indicating that 82% of students experienced a reduction in their disruptive behaviour. Interventions designed for individual students produced a very large mean effect size (ES = -0.85, SD = 0.31) compared to class-wide strategies (ES = -0.76, SD = 0.30). The most prevalent intervention was group contingencies included in 13 studies. The most utilised intervention within this group was the Good Behaviour Game. All interventions provided in the studies included in this meta-analysis resulted in a reduction in disruptive behaviour, however not all interventions had a strong representation across the studies and therefore have limitations. A small number of experiments trialling an intervention may produce a large effect size, however, due to the need for replication to evoke confidence in the efficacy of an intervention, these results are tentative at best. There is also a strong theme for more training for teachers in classroom management skills as many teachers are reporting that they are not equipped for managing disruptive behaviour in the classroom.

title: Instabilities of the cortex during natural sleep

authors: Wilson, Marcus T.

subjects: cortex

abstract: The electrical signals generated by the human cortex during sleep have been widely studied over the last 50 years. The electroencephalogram (EEG) observed during natural sleep exhibits structures with frequencies from 0.5 Hz to over 50 Hz and complicated waveforms such as spindles and K-complexes. Understanding has been enhanced by comprehensive intra-cellular measurements from the cortex and thalamus such as those performed by Steriade et al [1] and Sanchez-Vives and McCormick [2]. Models of the cerebal cortex have been developed in order to explain many of the features observed. These can be classified in terms of individual neuron models or collective models. Since we wish to compare predictions with gross features of the human EEG, we choose a collective model, where we average over a population of neurons in macrocolumns. A number of models of this form have been developed recently; that developed at Waikato draws from a number of different sources to describe the temporal and spatial dynamics of the system.

title: The development of guidelines for indigenous research ethics in Aotearoa/New Zealand.

authors: Hudson, Maui

abstract: The development of Indigenous frameworks for research ethics has been a key component of progressing Indigenous aspirations for research around the world. They have provided a focal point for challenging approaches to research that prioritise non-Indigenous methods and values, and allow non-Indigenous researchers to claim expert status over Indigenous peoples, places and knowledges. The theme of self-determination underpins contemporary approaches to Indigenous development and the repositioning of state-Indigenous nation relationships. This paper describes the background, development, and implementation by Māori communities and researchers of an Indigenous ethical framework in Aotearoa/New Zealand.
