Knowledge of scientific inquiry (SI) is considered essential to the development of an individual's Scientific Literacy (SL) and therefore, SI is included in many international science education reform documents. Two previous large scale international studies assessed the SI understandings of students entering middle school and secondary students at the end of their formal K-12 science education. The purpose of this international project was to use the VASI-E to collect data on what primary level students have learned about SI in their first few years of school. This study adds to previous research to bridge the landscape of SI understandings now with representation from primary, middle and high school samples. A total of 4,238 students from 35 countries/regions spanning six continents participated in the study. The results show that globally, primary students are not adequately informed about SI for their age group. However, when compared with the students in the previous international studies (grades seven and 12), the primary students' understandings were surprisingly closer to the levels of understanding of SI of the secondary school students than those in the seventh grade study.

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.

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 (M[subscript 2] = 1.061, SD[subscript 2] = 0.64) compared to the person measures before the implementation (M[subscript 1] = - 0.001, SD[subscript 1] = 0.591). The implications for learning progression of students are discussed.
