The shortage of graduates in Science, Technology, Engineering and Mathematics (STEM), has led to numerous attempts to increase students' interest in STEM. One emerging approach that has the potential to improve students' motivation for STEM is integrated STEM education. Nonetheless, the implementation of this new instructional strategy is not straightforward due to the lack of consensus about instructional practices in integrated STEM. This paper contributes to this challenge by providing a well-defined framework for instructional practices in integrated STEM in secondary education, based on the results of a systematic review of existing literature. The framework contains five key principles: integration of STEM content, problem-centered learning, inquiry-based learning, design-based learning and cooperative learning. The proposed framework has several benefits, including its applicability in the classroom and the possibility to describe integrated STEM on multiple dimensions. Nonetheless, further research is necessary to investigate the effects of integrated STEM on students' cognitive and affective learning outcomes.

In this paper, we explore how students' engagement varies in different STEM (Science, Technology, Engineering, Mathematics) learning environments. More specifically, we focus on the significance of a learning environment applying an integrated STEM (iSTEM) approach and the significance of STEM learning environments' student-centredness. Moreover, we explore the relative importance of different student-centred principles (lesson plan and implementation, communicative interactions, student-teacher relationships) for students' engagement in the STEM learning environment. Applying a mixed-method approach, we draw from observational data of 24 STEM lessons in combination with data from seven focus groups with 67 grade 9 students. The quantitative findings, based on the observational data, show that a learning environment applying an iSTEM approach seems to support students' engagement. Further investigation made it clear that the student-centredness in this learning environment is especially significant. Regarding the specific student-centred principles, all principles had a significant impact on students' engagement. The focus group data make clear that, besides student-centredness, the integrative aspect and the use of authentic real-world problems in iSTEM can also be engaging for students. These results indicate that iSTEM is a good practice to engage students in the STEM learning environment, as it facilitates teachers' implementation of a general student-centred approach.

A key theme in the science education literature concerns the reluctance of students to participate in Science, Technology, Engineering and Mathematics (STEM). Selfdetermination theory (SDT) states that social factors in an educational setting, such as teachers' motivating style, can influence students' motivation and engagement. This paper investigates the relationship between STEM-teachers' motivating style (autonomy support, provision of structure, involvement) and students' motivation and engagement with regard to STEM. Furthermore, the relationship between students' motivation and students' engagement is investigated. Thirty classroom observations were conducted in different STEM lessons, to assess teachers' motivating style and students' engagement. The students' motivation was assessed at the end of the school year, using an online questionnaire. The results reveal that STEM-teachers' provision of structure is positively linked to students' motivation and engagement with regard to STEM subjects. The impact of teachers' autonomy support was negatively predictive for students' autonomous motivation, and positively predictive for students' engagement. A negative relationship between students' controlled motivation and engagement was found. Based on these results, this study suggests that taking teachers' motivating style into account in future educational initiatives regarding STEM is highly relevant as a means of stimulating students' motivation and engagement.

We are increasingly exposed to complex societal and technological problems. Qualified Science, Technology, Engineering and Mathematics (STEM) professionals are needed to solve these problems and cope with contemporary demands such as sustainable energy and efficient healthcare [1]. It is not surprising then that the World Economic Forum's Future of Jobs Report (2016) predicted a job gain in STEM fields for the following years [2]. However, we do not only need STEM professionals who can solve these problems. We also need people with a certain level of basic STEM literacy. All citizens, even non-STEM professionals, should have the skills and competences necessary to deal with the challenges of our information-based and highly technological society [3]. STEM-literacy, i.e., the awareness of the nature of science, technology, engineering, and mathematics, and the familiarity with fundamental concepts from each discipline, should be an educational priority for all students [3], [4].

Hard science': a career option for socially and societally interested students? Grade 12 students' vocational interest gap explored.A key theme in science education research concerns the decline in young peoples' interest in science and the need for professionals in hard science. Hard science typically includes technology, engineering, mathematics, physics and, to some extent, chemistry. Goal Congruity Theory posits that an important aspect of the decision whether to pursue hard science for study or as a career is the perception that hard science careers do not fulfil social (working with people) and societal (serving or helping others) interests. In this qualitative study, we explore grade 12 students' perceptions about the social and societal orientation of hard science careers. Furthermore, we investigate the variation in students' social and societal interests. Six focus groups were conducted with 58 grade 12 students in Flanders. Our results indicate that students hold very variable perceptions about hard science careers' social orientation. A number of students hold stereotypical views, while others believe cooperation with others is an important aspect of hard science careers nowadays. Students with clear perceptions often refer to role models, such as parents. Furthermore, our results show that students believe hard science careers can be societally oriented in the sense that they often associate them with innovation or societal progress. Finally, our results indicate that students may differentiate direct versus indirect societal orientation. These findings contribute to literature regarding social and societal interests and students' perceptions of hard science careers' social and societal orientation.
