Principles of Pedagogy and Evaluation for Web-Based Learning

The authors have designed a number of courses at Arizona State University, which were delivered on the internet and supported with computer conferencing software. In this paper the authors will present an online course, discuss issues relating to online learning environments, reflect on their experiences from teaching online and discuss the findings of the course evaluation. Emphasis of the discussion will be on the pedagogical principles for effective teaching and evaluation of learning in an online environment.

Analyzing Learning About Conservation of Matter in Students While Adapting to the Needs of a School

We probed the impact of two teaching strategies, guided inquiry and argumentation, on students' conceptual understanding of the conservation of matter. Conservation of matter is a central concept in middle school science curriculum and a prerequisite upon which rests more complex constructs in chemistry. The results indicate that guided inquiry was particularly effective in improving students' conceptual understanding, as evidenced by pre/posttest results and by a skill analysis of in-depth interviews of student dyads. We also discuss how the challenges inherent to educational contexts can undermine the quality and limit the impact of empirical research carried out in many schools. We suggest how these challenges could be met in the emerging infrastructures for change called the Research Schools Network.     

Cardiac autonomic and haemodynamic recovery after a single session of aerobic exercise with and without blood flow restriction in older adults

This study investigated the autonomic and haemodynamic responses to different aerobic exercise loads, with and without blood flow restriction (BFR). In a crossover study, 21 older adults (8 males and 13 females) completed different aerobic exercise sessions: low load without BFR (LL) (40% VO_2max), low load with BFR (LL-BFR) (40% VO_2max + 50% BFR) and high load without BFR (HL) (70% VO_2max). Heart rate variability and haemodynamic responses were recorded during rest and throughout 30 min of recovery. HL reduced R–R interval, the root mean square of successive difference of R–R intervals and high frequency during 30 min of recovery at a greater magnitude compared with LL and LL-BFR. Sympathetic–vagal balance increased the values for HL during 30 min of recovery at a greater magnitude when compared with LL and LL-BFR. Post-exercise haemodynamic showed reduced values of double product at 30 min of recovery compared to rest in LL-BFR, while HL showed higher values compared to rest, LL-BFR and LL. Reduced systolic blood pressure was observed for LL-BFR (30 min) compared to rest. Autonomic and haemodynamic responses indicate lower cardiovascular stress after LL-BFR compared to HL, being this method, besides the functional adaptations, a potential choice to attenuate the cardiovascular stress after exercise in older adults.     

Does Cross-cultural Competence Matter when Going Global: Cultural Intelligence and Its Impact on Performance of International Students in Australia

Cultural Intelligence (CQ) is a critical competency in the modern world. By examining 189 international students from an Australian university, this study investigates the impact of CQ and cultural exposure on intercultural adjustment and academic performance. Significant positive relationships are found between facets of CQ and Interactional Adjustment and General Adjustment, but a significant negative relationship with Academic Performance. We also demonstrate the validity of a new construct of Cultural Exposure (CE) including three dimensions (Geographical, Environmental, and Inherited) with both Geographical and Environmental dimensions producing a strong positive correlation with Academic Performance.     

Examining between‐group and within‐group effects of a peer‐assisted reading strategies intervention

The present study sought to evaluate the effects of a reading strategy instructional program on the reading competence of third‐grade students. Students were instructed in fluent and strategic reading by trained research assistants in whole class settings and subsequently worked on expository text material together with peers. Their reading competence was assessed continuously: in the baseline phase prior to the intervention (4 times), while the intervention was in place (8 times), and after the end of the intervention (4 times). Additionally, reading competence in the wait list control students was assessed 8 times during the same time period. Accordingly, within‐ and between‐group comparisons of students’ test scores were conducted on the data, with both resulting in significant positive effects on the reading competence of intervention students. This research provides an example of how to strengthen the validity of quasiexperimental intervention research through the addition of design features like multiple measurement points.     

A systematic analysis of performance measures for classification tasks

This paper presents a systematic analysis of twenty four performance measures used in the complete spectrum of Machine Learning classification tasks, i.e., binary, multi-class, multi-labelled, and hierarchical. For each classification task, the study relates a set of changes in a confusion matrix to specific characteristics of data. Then the analysis concentrates on the type of changes to a confusion matrix that do not change a measure, therefore, preserve a classifier’s evaluation (measure invariance). The result is the measure invariance taxonomy with respect to all relevant label distribution changes in a classification problem. This formal analysis is supported by examples of applications where invariance properties of measures lead to a more reliable evaluation of classifiers. Text classification supplements the discussion with several case studies.     

Leading for social justice in challenging school contexts

This article is part of the International Successful School Principalship Project (ISSPP) and aims to analyse the success factors of two Spanish secondary school principals working in the line of social justice in challenging contexts. The factors are arranged in traits and beliefs of principals and in the strategies they used to bring successful leadership. The article concludes by showing a model of leadership that emphasizes both personal and professional characteristics of principals and their central role as agents of social change.     

Untangling the conflation of ‘young adults’ and ‘young people’ in STI and sexual health policy and sex education

Young adults, aged 18–30 years, are disproportionally mentioned in sexually transmissible infection surveillance data both in Australia and internationally. This contributes to categorising young adults as an ‘at risk’ group in health policy. How young adults are framed in policy, and what informs this, have direct implications for policy priorities and responses, including the development of health promotion programmes. In this paper, we provide a case study of Australia’s National Strategies for Blood Borne Viruses and Sexually Transmissible Infections from 2005 to 2017. We identify how ‘young adults’ as a population are masked by, and subsumed within, the broader category of ‘young people’ within these strategies. As a result, young adults become framed by default as a ‘risk category’ that requires education to correct its deficits, regardless of personal experience. For health promotion to advocate, mediate and enable better sexual health outcomes, a policy environment is needed that reflects the changing social and cultural contexts and sexual independence that young adults experience. Sexual health policies should reflect the complexity and opportunities of young adulthood if we are to offer an enabling policy environment for innovative and nuanced health promotion strategies, including adult appropriate health education.
