Predicting the academic achievement of first-year,pre-service teachers: the role of engagement,motivation, ATAR,and emotional intelligence

Australian universities are enrolling a larger and more diverse undergraduate student population. Counter to this trend, several states have developed plans to restrict entrance into the teaching profession. This study investigates the role of engagement, motivation, Australian Tertiary Admission Rank (ATAR), and emotional intelligence in the academic achievement of first-year, pre-service teachers. Eighty-three regionally enrolled pre-service teachers agreed to complete self-report questionnaires that assessed engagement with learning and emotional intelligence. The questionnaire data were supplemented with findings from a series of focus groups. Although ATAR scores were found to be a significant predictor of academic achievement, scores on the Motivation and Engagement Scale emerged as a much stronger predictor of first-year grade point average. Measures of emotional intelligence did not add to the model. The results support the need to consider pre-service teachers’ motivation and engagement with learning, especially given the high stakes nature of proposed reforms to initial teacher education programmes.     

Language-specific phonological skills and the relationship with reading accuracy in Sylheti-English sequential bilinguals

This study investigated the influence of first language (L1) phonology on second language (L2) early reading skills in Sylheti-English bilinguals (N = 58; 48% girls; British Bangladeshi) and their monolingual-English peers (N = 43; 45% girls; 96% White British, 4% multiethnic British) in a diaspora context. Language-specific phonological awareness and nonword repetition were tested at two time points (6;2–7;8 years-old). At Time 1, the bilinguals had lower productive accuracy for phonological sequences that violated their L1 phonology (d = .56; .84), and these skills accounted for a significant amount of variance in their reading accuracy. At Time 2, the language-specific effects were no longer present. These findings highlight the importance of considering language structure in multilingual early literacy development.     

The state of evidence for social and emotional learning: A contemporary meta-analysis of universal school-based SEL interventions

This article provides a systematic review and meta-analysis of the current evidence for universal school-based (USB) social and emotional learning (SEL) interventions for students in kindergarten through 12th grade available from 2008 through 2020. The sample includes 424 studies from 53 countries, reflecting 252 discrete USB SEL interventions, involving 575,361 students. Results endorsed that, compared to control conditions, students who participate in USB SEL interventions experienced significantly improved skills, attitudes, behaviors, school climate and safety, peer relationships, school functioning, and academic achievement. Significant heterogeneity in USB SEL content, intervention features, context, and implementation quality moderated student experiences and outcomes. Strengths and limitations of this evidence and implications for future USB SEL research, policy, and practice are discussed.     

Microfluidic concentration of bacteria by on-chip electrophoresis

In this contribution, we present a system for efficient preconcentration of pathogens without affecting their viability. Development of miniaturized molecular diagnostic kits requires concentration of the sample, molecule extraction, amplification, and detection. In consequence of low analyte concentrations in real-world samples, preconcentration is a critical step within this workflow. Bacteria and viruses exhibit a negative surface charge and thus can be electrophoretically captured from a continuous flow. The concept of phaseguides was applied to define gel membranes, which enable effective and reversible collection of the target species. E. coli of the strains XL1-blue and K12 were used to evaluate the performance of the device. By suppression of the electroosmotic flow both strains were captured with efficiencies of up to 99%. At a continuous flow of 15 μl/min concentration factors of 50.17 ± 2.23 and 47.36 ± 1.72 were achieved in less than 27 min for XL1-blue and K12, respectively. These results indicate that free flow electrophoresis enables efficient concentration of bacteria and the presented device can contribute to rapid analyses of swab-derived samples.
