Background Despite the focus of many global education systems on science, technology, engineering, and mathematics (STEM) education, research on teachers' concerns about this relatively new educational phenomenon remains scarce. Purpose This study used the concerns-based adoption model as the theoretical framework to examine the primary concerns expressed by teachers about STEM education and identified a typology of teachers based on the response patterns of their concerns. Sample A regionally representative sample of 331 primary and secondary school teachers of STEM-related subjects in Hong Kong participated in this study. Design and methods Data were collected from the teachers through an online, self-reported survey. Latent class analysis was used to profile teachers' concerns about STEM education in this study, and multinomial logistic regression analysis was performed to regress the latent class outcome variable on the covariates. Results The majority of the teachers reported high levels of concern at all five stages of STEM education implementation, namely evaluation, information, management, consequence, and refocusing. Latent class analysis revealed three classes of teachers who were extremely concerned (49.1%), considerably concerned (43.5%), or moderately concerned (7.4%) about STEM education. Multinomial logistic regression analysis indicated that the teaching sector (primary or secondary) and participation in STEM education training significantly contributed to the prediction of the latent class outcome variable. Conclusion Given that 96% of the teachers in this study were trained in STEM education through workshops, seminars, courses, and trips, these findings highlight the necessity of designing personalized professional learning experiences for teachers and provide empirically supported evidence to indicate teachers' preparedness and readiness to adopt STEM education as an educational innovation and directions for future research in related areas.

Background: STEM education and research are increasingly emphasized by governments worldwide to foster national development and productivity, economic competitiveness and societal wellbeing. There is no exception in Hong Kong, with its desire to promote STEM education and to strengthen Innovation and Technology development in the future. Purpose: This study aimed to explore the STEM activities employed in primary students' STEM projects under the theme 'Living in a Smart City', and to identify what and how computation technologies were generally used and to examine the differences of computation technology used among project types and award levels. Sample: 168 project reports were collected from a STEM Fair with the following areas of content: the origins of the inquiry idea; scientific/STEM theories employed; inquiry process and testing methods implemented; findings and results obtained; difficulties encountered; and students' reflections. Design and methods: Content analysis on project reports and students' reflections was performed. The qualitative data were coded for statistical analysis, to explore the differences in the association of the STEM activities in the projects. Analyses were supported by students' reflections in the reports to explore students' computation experiences. Results: Most students worked on new device projects, and projects producing new devices were more likely to integrate technological activities. On the whole, science, engineering and mathematics activities complemented each other well, with less evidence of integration with respect to technology activities. Students gained valuable knowledge and got a sense of achievement from the STEM project work. Conclusion: It is encouraging to find that students were capable of integrating STEM activities to different extents into STEM projects. It is noticed that more emphasis should be laid on promoting the infusion of computation technological activities. More attention should also be paid on providing

School-based assessment of science students' practical skills has two important roles—as a complement to written papers in public examinations and as a catalyst for enriching the science curriculum in schools. This article describes a quantitative study of the concerns chemistry and biology teachers experience as they engage in the process of implementation of a school-based assessment scheme for practical work. A 23-item questionnaire was developed to measure five categories of teacher concern: evaluation, information, management, consequence and refocusing. The nature of each category of teacher concern is discussed in relation to innovation adoption and implementation. Data were collected from 400 chemistry and 412 biology teachers in Hong Kong. Teachers' information and management concerns lessened in intensity when they became experienced users of a school-based assessment scheme. However, teaching experience alone could not motivate teachers to think more about the impact of school-based assessment on student learning, their professional development in student assessment and the possible refinements in their school-based assessment scheme. Concerns-based interventions are suggested to help teachers grow professionally.
