Given that teacher shortage is an international problem, teacher job satisfaction merits closer attention. Not only is job satisfaction closely related to teacher retention, but it also contributes to the well-being of teachers and their students, overall school cohesion and enhanced status of the teaching profession. This study investigates the relations between teacher job satisfaction, school working conditions and teacher characteristics for eighth grade mathematics teachers. The study employs TIMSS 2015 (Trends in International Mathematics and Science Study) data from Sweden. Confirmatory factor analysis and structural equation modelling are used as main methods. Results demonstrate a substantial association between school working conditions and teacher job satisfaction. More specifically, teacher workload, teacher cooperation and teacher perceptions of student discipline in school were the factors most closely related to teacher job satisfaction. As to teacher characteristics, female teachers, teachers with more exposure to professional development and more efficacious teachers tended to have higher levels of job satisfaction. In addition, it was found that the relationship between the extent of teacher cooperation and job satisfaction was more pronounced for male teachers, while student discipline was more important for job satisfaction of teachers with lower self-efficacy beliefs. Implications for policy are further discussed.

This study explores how aspects of teacher quality are related to student achievement and students' perceptions of instructional quality on the basis of eighth grade TIMSS 2011 data for Sweden. Indicators of teacher quality are coursework in mathematics as measured by the number of semesters of studying mathematics, years of teaching experience and teacher self-efficacy beliefs. The study employs confirmatory factor analysis and structural equation modelling as primary methods. Results indicate that teachers with higher self-efficacy beliefs were rated by students as delivering higher instructional quality. However, this was not reflected in student achievement levels. Instead, with student socioeconomic and immigrant background under control, there was a significant positive relationship between coursework in mathematics and student mathematic achievement levels, as well as between student perceptions of instructional quality and achievement. Relations between teaching experience and student achievement followed a non-linear pattern, with the effect of teaching experience increasing up to 19 years and declining afterwards.

Colloids of metal nanoparticles (NPs) of Au, Ag, Pd, and Pt protected by natural polymer arabinogalactan (ARB) extracted from Larix sibirica were studied. The nanocomposites were prepared by reduction of metal salts in the water solutions of ARB. We carried out dynamic (DLS) and static light scattering resonantly enhanced by the NP plasmons. The translational diffusion was examined via DLS and a polarized interferometer. The virgin ARB was shown to form aggregates in dilute aqueous solutions. The introduction of NPs reduced the size of the virgin ARB aggregates. The aggregate forms as viewed by the scanning electron microscopy support the light scattering results.

Background There is limited research on prevention of mental ill-health of school personnel and the systematic management of school work environments. The aim of this study was to assess the effectiveness of implementing the guideline recommendations for the prevention of mental ill-health in schools, in particular, whether there was a difference in adherence to guideline recommendations between a multifaceted (group 1) and single implementation strategy (group 2) from baseline to 6 and to 12 months. Method We conducted a cluster-randomized controlled trial with a 6- and 12-month follow-up. Data was collected from nearly 700 participants in 19 Swedish schools. Participants were school personnel working under the management of a school principal. The single implementation strategy consisted of one educational meeting, while the multifaceted implementation strategy comprised an educational meeting, an ongoing training in the form of workshops, implementation teams and Plan-Do-Study-Act cycles. Adherence was measured with a self-reported questionnaire. Generalized Linear Mixed Models were used to assess the difference between groups in adherence to the guideline between baseline, 6-, and 12-months follow-up. Results There were no statistically significant differences between the groups in improvements in adherence to the guideline between baseline, 6-, and 12-months follow-up. However, among those schools that did not undergo any organizational changes during the 12 months of the study significant differences between groups were observed at 12 months for one of the indicators. Conclusions The multifaceted strategy was no more effective than the single strategy in improving guideline adherence. There are some limitations to the study, such as the measurement of the implementation outcome measure of adherence. The outcome measure was developed in a systematic manner by the research team, assessing specific target behaviors relevant to the guideline recommendations, however not psychometrically tested, which warrants a careful interpretation of the results.
