Factors Affecting the Study of Chemistry in Different Countries Around the World: Findings from an International Survey

Improving teaching and student learning in chemistry classrooms is an important goal that is constantly researched. Several comparative studies of science teaching have been carried out on different parameters, e. g. misconceptions which science teachers and students may have regarding the scientific concepts they learn and teach. Here we describe science teaching in general, and chemistry teaching in particular, in 12 countries including Israel. Different parameters are compared, including the hours that are devoted to science, the subjects included, the pedagogy, and teachers′ salaries. The survey covers all school levels: elementary school, secondary school and high school. At the high‐school level, the comparison focused on chemistry studies. In this study the variances variables, such as the hours that are allocated for science teaching, did not show an appreciable effect on students′ achievements. It was also found that, in countries where chemistry studies at the high‐school level are not mandatory, innovative pedagogies are more likely to replace the traditional chemistry teaching methods where chemistry is taught according to the structure of the subject based on basic concepts that underlie the curriculum. The study provided an additional support to the importance of the professional development of science and chemistry teachers and suggest that the autonomy that is given to them could influence the quality of science teaching and students′ achievements.

Psychological Contract and Turnover Intention in the Information Technology Profession

The recruitment and retention of Information Technology (IT) professionals continue to concern organizations and researchers. We employ psychological contract theory to examine how unmet expectations may influence psychological contract breach and turnover intention. The results of a survey of IT professionals indicate four factors contributing to IT workers’ perceptions of psychological contract breach including perceived supervisor support, emotional dissonance, work exhaustion, and salary. Further, autonomy moderates the relationship between psychological contract breach and turnover intention.     

Teacher beliefs and technology integration practices: A critical relationship

Early studies indicated that teachers’ enacted beliefs, particularly in terms of classroom technology practices, often did not align with their espoused beliefs. Researchers concluded this was due, at least in part, to a variety of external barriers that prevented teachers from using technology in ways that aligned more closely with their beliefs. However, many of these barriers (access, support, etc.) have since been eliminated in the majority of schools. This multiple case-study research was designed to revisit the question, “How do the pedagogical beliefs and classroom technology practices of teachers, recognized for their technology uses, align?”     

Flora Crockett Stephenson (1914–1979): A life and professional partnership in planning

This article contributes to the growing literature on women's contributions to planning, especially in the UK, the USA, and Australia, and to research into the phenomenon of life partners who work together professionally. The subject is Flora Crockett Stephenson (1914–1979), the first woman to complete the Master in City Planning degree at the Massachusetts Institute of Technology. Presented as a biographical exposé, the discussion introduces Flora's background and reveals her largely unrecorded contributions as the life and professional partner of British architect-planner Gordon Stephenson (1908–1997), already the subject of several academic studies.     

浅析职业教育教师新定位

学生的学习成长是一个富有重要意义的过程,在这个过程中,教师所要扮演的首先是一个组织者。在组织的过程中引导学生通过正确的途径掌握科学的学习方法和习惯,突出学生学习的主体地位。其次,和学生一起学习的过程是教师融入到学生学习过程的最重要方法,并在学习过程中适时、适宜的起到启迪的作用。第三,在学生获得成绩和遇到困难时发挥一个心理点拨者的作用,不断激励,让学生有一个持续学习的动力。最后,用欣赏的眼光看待学生的点滴进步,包容学生的不足,做亲切和善的心灵导师。
