The issue of integrated STEM curriculum design and evaluation requires a more consistent understanding and clarity among STEM educators. In this paper, we propose an instructional framework of STEM integration based on the theoretical notions of disciplinarity and problem-centred learning. The proposed S-T-E-M Quartet instructional framework utilises complex, persistent and extended problems at its core, and the problem solving process as the overarching frame. The key difference between the proposed S-T-E-M Quartet instructional framework and models such as the STEM road map and the Cubic model for STEAM education is the emphasis on the connections between different disciplines. Similar to the STEM road map, the application of the S-T-E-M Quartet framework begins with a single lead discipline as the focus and subsequently examines how knowledge and skills of the lead discipline are connected and related to the other three disciplines. As an instructional framework, the S-T-E-M Quartet requires description of learning outcomes for each discipline when students work with the problem. The learning outcomes within individual disciplines constitute the vertical learning within a discipline. Depending on the problem described, the learning outcomes for some disciplines might be more in-depth than others. As the S-T-E-M Quartet foregrounds connections between disciplines, attention is also paid to the strength of connections, whether they are weak, moderate or strong. A case example of application of the S-T-E-M Quartet instructional framework is presented as an illustration of how the S-T-E-M Quartet instructional framework can be used to design and reflect on STEM tasks.

This study describes an inquiry approach involving a practitioner-researcher partnership and examines its impact on teachers' capacities to conduct explicit instruction of disciplinary literacy. The partnership comprised iterative cycles of sessions that engaged content teachers in exploring their students’ language challenges using student writing as the stimulus of inquiry. Data from the inquiry sessions and lessons provided evidence of the impact of the inquiry on the teachers. The impact includes self-reported changes in their language sensitivity, beliefs and assessment practices as well as observable changes in their classroom instruction. The relationship between the impact and teacher language awareness are discussed.

This article presents an empirical study of the use of Indigenous knowledge of the Bulan kite to teach the concept of “equilibrium” among Muslim students (n = 109 students) in private Islamic schools (in the southern part of Thailand). The design of the culturally responsive teaching comprising three lessons was guided by the 5E model. The study took 7 months from creating three lesson plans and a pre- and post-test until it was implemented in the physics classroom. A pre- and a post-test with 40 multiple-choice items were used to assess students’ understanding of equilibrium. A hypothetical model of the construct was validated using a dichotomous Rasch model. To measure learning gains, we fixed the pre- and post-item difficulties and estimated the post-instruction person’s ability. The Welch t-test was used to compare the means of pre- and post-instruction person ability. The results indicated that the Rasch model fits the data well. The hypothetical model was confirmed. The successful students showed the person measures with a statistically significant increase (p < 0.01) at the end of the intervention (M₂ = 1.061, SD₂ = 0.64) compared to the person measures before the implementation (M₁ =  − 0.001, SD₁ = 0.591). The implications for learning progression of students are discussed.

STEM education and research has gained popularity internationally over the last decade. However, there is a lack in specifications in existing K-12 STEM classroom observation protocols of how features of an integrated STEM experience/lesson would lead to desired outcomes and how those outcomes should be measured. To bridge this gap, we propose the development of a new integrated STEM classroom observation protocol (iSTEM protocol). This article describes the ongoing development work of the iSTEM protocol, which features two creative attempts. Firstly, the productive disciplinary engagement framework is adapted to design a classroom observation protocol that provides a coherent frame of design principles to be met to achieve desired 3-dimensional pedagogical outcomes. Secondly, interdisciplinarity of student engagement was interpreted in terms of the extent to which students take a systematic and disciplinary-based approach to make and justify decisions during STEM problem-solving. The iSTEM protocol comprises 15 items (4-point scale) rated holistically for the extents to which evidence was found in the observed lesson for (1) the 3-dimensional pedagogical outcomes of productive interdisciplinary engagement (five items) and (2) problematising, resources, authority, and accountability design principles (10 items). The accompanying iSTEM profile visually represents and communicates the strengths and inadequacies in design principles, thus providing explanations for extents of students’ productive interdisciplinary engagement. The iSTEM protocol will contribute as a research tool for STEM education researchers and as a pedagogical guide for STEM classroom teachers to improve their design of STEM learning experiences.

Plants are fundamental to the existence of our green planet, but the understanding of plants and the willingness to understand them is deficient. Teachers, students and curriculum developers are mindful of the lack of knowledge and ability to notice plants in our environment. In Singapore we are facing a paradox in plant science education. Known as a garden city, and having a hybrid of an orchid as our national flower, many of our citizens ironically remain blind to what are growing and cultivated around them. Our pupils are not able to name the common plant species. They would prefer to dwell in the air-conditioned comfort of their homes and learn through the computer or the television rather than to have a walk in the forest. Further, our educators merely set limited plant contents in Biology syllabus, and teachers are reluctant to bring plants to the classroom. In this review, we reflect plant science education in Singapore based on the current syllabus at the primary, secondary and junior college levels. We also list a few case studies of specific terms in plant science using various science textbooks and questions from national exams to allow a greater understanding on how plant science is taught and tested. Finally we propose suggestions to improve plant science education in Singapore.

This research reports the considerations influencing task selection for formative assessment among 30 primary school science teachers. Education and assessment are high stake enterprises in this multicultural city-state of Singapore. The 39 participants were chosen through random sampling from six primary schools located at different parts of Singapore. The participants responded to an instrument comprising of activities on the concepts of electrical circuits and conductors. The activities, set in different contexts but based on the same learning outcomes, were presented to the participants as possible tasks to assess students' learning. The participants’ responses to the questions were analysed. The findings revealed that the teachers prioritised students' abilities and their learning over and above other factors. The writers argued that the teachers' focus on students’ abilities may work against the current initiative of inquiry approach towards teaching and learning. While studies on teachers' conceptions on assessment have been undertaken, the contribution of this paper lies in illuminating influences on the implementation of formative assessment in Singapore primary science classrooms.

Singapore students boast stellar performance at international benchmarking studies such as PISA and TIMSS. One of the major contributors to the consistently good performance in mathematics and science is the quality of our science teacher education in Singapore. Through a consistent, systematic and continuous system, there is a seamless transition of pre-service teacher education to continuing professional development of science teachers in Singapore. This pathway of science teacher education is important as it enables science teachers to be kept abreast of changing educational innovations. Quality of science teachers is ensured from the first step of recruitment. Prospective teachers undergo a stringent selection process before they are admitted to the National Institute of Education for their pre-service education. Factors such as strong governmental support, resource availability, high quality professional development opportunities that are responsive to changes in educational landscape, and presence of a structure to allow planning and tracking of professional development trajectory ensures quality professional development. As such, science teacher education in Singapore is a compact model that is responsive yet stable, flexible yet structured, bespoke yet inclusive, varied yet focused, and specialized yet accessible. This paper will discuss science teacher education and professional development in the light of the larger Singaporean education landscape. It will also present challenges and way ahead for science teacher education and professional development in Singapore.

Researchers have indicated that assessment practices and methods ought to be tailored to support learners’ construction of meaningful understanding of knowledge. To achieve this aim, understanding students’ conceptions of science assessment would be essential since it will enable us to construct more realistic, valid and fair assessments. Understanding how learners conceptualize assessment would be imperative to serve as an essential reference to properly evaluate their learning progress. The main purpose of this study was to evaluate and compare the Singaporean and Taiwanese middle school students’ conceptions of science assessment. Within each country, gender comparisons were also explored. A total of 333 Singaporean and 424 Taiwanese grade eight students were invited to complete a questionnaire named Conceptions of Science Assessment (COSA) to capture their views on science assessment. The results indicated that, first, the COSA questionnaire was valid and reliable for measuring the Singaporean and Taiwanese eighth graders’ conceptions of science assessment, including Surface, Summative, and Formative conceptions. Second, the findings showed that the summative purpose of assessment still dominates in the Taiwanese science classroom, while both formative and summative purposes of assessment are usually perceived in Singaporean science classrooms. In contrast, the Singaporean students had a greater tendency than their Taiwanese counterparts to perceive the surface purpose of assessment as merely a way of reproducing scientific knowledge, and the formative purpose of assessment as improving learning, problem solving and critical judgment. No gender differences were found among either the Singaporean or the Taiwanese students regarding their three science assessment conceptions. The findings suggest that science educators in both countries should provide learners with more opportunities to experience process-oriented science assessment activities and de-emphasize the usage of examination-oriented practices to achieve the sophistication of conceptions.
