School-based citizen-science can be a powerful means to engage youth in environmental education, yet developing robust science curricula around citizen-science activities is tremendously challenging. Prior research provides limited examples and very little guidance for curriculum designers. To support the designers of school-based citizen-science…

Recent reforms in K-12 science education call for curricular materials that are designed to be "coherent for students." This form of coherence arises when the classroom community sees their science work as addressing their questions and problems. In enactment, the teacher sometimes has to improvise from the planned trajectory of the…

It is generally considered that students who want to become scientists engage in scientific practices as university students, particularly when pursuing postgraduate studies. However, schools and teachers can help students participate in authentic scientific and disciplinary practices, such as data sampling and analysis, in high school. The…

Literature shows that science teachers' development and practice of PCK have always been a concern in science education research. Globally, national policies have begun to underscore the instruction of science teachers as a great concern. This study is considered worthwhile, as it intended to address this gap by exploring a beginner teacher's PCK…

Mastery goal structures, which communicate value for developing deeper understanding, are an important classroom support for student motivation and engagement, especially in the context of science learning aligned with the Next Generation Science Standards. Prior research has identified key dimensions of goal structures, but a more nuanced…

Laser-induced breakdown spectroscopy (LIBS) and principal component analysis (PCA) are frequently used for analytical purposes in research and industry, but they seldom are part of the chemistry curriculum or laboratory exercises. This case study paper describes the combined application of LIBS and PCA during a research internship for an…

Background and purpose: To date, there has been little research on the Teacher Professional Development (TPD) for delivering a mobile technology-supported science curriculum. To address this, a TPD model for a science curriculum supported by mobile technology was developed and evaluated in this paper. The study reported focuses on the…

The article focuses on the analysis of curriculum documents from Taiwan to investigate how benchmarks for learning nature of science (NOS) are positioned in different versions of the science curricula. Following a review of different approaches to the conceptualization of NOS and the role of NOS in promoting scientific literacy, an empirical study…

The theme that structure determines function is one of the most significant cornerstones in understanding natural sciences. On the other hand, recently revised science curriculum in Turkey has emphasized science and engineering practices to help students be able to converge science with the other disciplines by applying theory into practice and…

Recent calls to reform undergraduate biology education, including Vision and Change in Undergraduate Biology Education, have led biology departments to examine their curriculum to determine the extent to which it aligns with Vision and Change content and competency recommendations. The recently released BioSkills Guide translates the broad Vision…

This article is a qualitative study, which was done in 2013-2014. In this study using a comparative study was conducted to compare physics curriculum elements of Iran with the countries studied. Countries studied: Singapore, Turkey, India, England and Australia have diverse educational system. In this study, the structure of the educational…

This study focused on how science teachers' content knowledge influences their pedagogical content knowledge (PCK) with respect to the topic of cell division. The data were collected from 3 in-service teachers using interviews; observations; and teacher-provided documents, including written-answer exams. The participants' content knowledge was…

The purpose of this study was to determine the science teachers' perceptions of and beliefs about integrated science, technology, engineering, and mathematics (STEM) education in the science curriculum. A case study research method was used to determine teachers' perceptions and beliefs of integrated STEM education in the science curriculum. The…

To promote rich discourse around scientific and engineering practices, teachers may turn to engineering design-based science curricula; however, this has discursive demands which have yet to be examined in a unit focused on integration of engineering and science. To investigate these discursive demands, we expand on the definition of discourse to…

Secondary science teachers make many daily decisions in the enactment of curriculum. Although curriculum materials are widely available to address science content, practices, and skills, the consideration that goes into deciding how and whether to use such materials is complicated by teachers' beliefs about science, their understandings of…
