The recent groundswell of interest in computer science education across many countries has created a pressing need for computing teachers at the secondary level. To satisfy this demand, some educational systems are drawing from their pool of in-service teachers trained in other disciplines. While these transitioning teachers can learn about computing pedagogy and subject matter at professional learning workshops, daily teaching experiences will also be a source of their learning. We studied a co-teaching program where instructional responsibilities were distributed between teachers and volunteers from the tech industry to explore how specific teaching practices supported teacher learning, with a focus on pedagogical content knowledge (PCK). Through qualitative analysis of questionnaire and interview data gathered from three teachers during one school year, we identified the practices they engaged in and how their learning related to the enactment of those practices. Our results highlight several factors that influenced the ways in which teaching practices provided participants with opportunities to learn PCK: (a) active participation of students and volunteers; (b) teacher’s level of content knowledge; (c) interdependent practices; and (d) immediacy of the classroom environment.

Factors Associated with High-Quality Computer Science Instruction: Data from a Nationally Representative Sample of High School Teachers
This paper shares results from surveys administered in spring 2018 to a nationally representative sample of nearly 300 U.S. high school computer science teachers. It describes the nature of high school computer science instruction and the extent to which teacher background, classroom factors, and school context predict the type of instruction students experience. Data from the study were analyzed using path modeling-a form of regression analysis that estimates both direct and indirect effects (i.e., through intermediary variables)-to examine relationships between teacher, classroom, and school factors, and the extent to which teachers (1) emphasize reform-oriented instructional objectives (e.g., learning about real-life applications of computer science) and (2) engage students in computer science practices (e.g., recognizing and defining computational problems). Sample findings include that students are most commonly engaged in activities related to testing and refining computational artifacts, but are less often engaged in aspects of computer science related to end users (e.g., create a computational artifact to be used by someone else). The path analysis highlights several factors that are related to greater engagement of students in the computer science practices, including teacher participation in professional development and the use of coherent instructional materials.

IntroductionElementary teachers face many challenges when including reform-based science instruction in their classrooms, and some teachers have chosen to enhance their science instruction by introducing students to citizen science (CS) projects. When CS projects are incorporated in formal school settings, students have an opportunity to engage in real-world projects as they collect and make sense of data, yet relatively few CS projects offer substantial guidance for teachers seeking to implement the projects, placing a heavy burden on teacher learning. MethodsFramed in theory on teacher relationships with curricula, we prepared science standards-aligned educative support materials for two CS projects. We present convergent mixed methods research that examines two teachers’ contrasting approaches to including school-based citizen science (SBCS) in their fifth-grade classrooms, each using support materials for one of the two CS projects. Both are veteran teachers at under-resourced Title 1 (an indicator of the high percentage of the students identified as economically disadvantaged) rural schools in the southeastern United States. We document the teachers’ interpretations and use of SBCS materials for the CS projects with data from classroom observations, instructional logs, teacher interviews, and student focus groups. ResultsOne teacher adapted the materials to include scaffolding to position students for success in data collection and analysis. In contrast, the second teacher adapted the SBCS support materials to maintain a teacher-centered approach to instruction, identifying perceptions of students’ limited abilities and limited instructional time as constraining factors. DiscussionWe discuss the intersection of CS projects in formal education and opportunities for engaging students in authentic science data collection, analysis, and sense-making. The two teachers’ stories identify the influences of school context and the need for teacher support to encourage elementary teachers’ use of SBCS instruction to supplement their science instruction.more » « less

We describe a professional development model that supports teachers to integrate computational thinking (CT) and computer science principles into middle school science and STEM classes. The model includes the collaborative design (co-design) (Voogt et al., 2015) of storylines or curricular units aligned with the Next Generation Science Standards (NGSS Lead States, 2013) that utilize programmable sensors such as those contained on the micro:bit. Teachers spend several workshops co-designing CT-integrated storylines and preparing to implement them with their own students. As part of this process, teachers develop or modify curricular materials to ensure a focus on coherent, student driven instruction through the investigation of scientific phenomena that are relevant to the students and utilize sensor technology. Teachers implement the storylines and meet to collaboratively reflect on their instructional practices as well as their students’ learning. Throughout this cyclical, multi-year process, teachers develop expertise in CT-integrated science instruction as they plan for and use instructional practices that align with three dimension science teaching and foreground computational thinking. Throughout the professional learning process, teachers alternate between wearing their “student hats” and their “teacher hats”, in order to maintain both a student and teacher perspective as they co-design and reflect on their implementation of CT-integrated units. This paper illustrates two teachers’ experiences of the professional development process over a two-year period, including their learning, planning, implementation, and reflection on two co-designed units.more » « less

To support students’ learning, a wide body of research and instructional reforms emphasize students’ engagement in productive talk with rigorous thinking in science classrooms. However, despite efforts, productive science talk is not yet prevalent in many classrooms. To gain more insight into the generation of productive talk in science classrooms, we explored a group of science teachers’ instructional vision and practices with respect to promoting classroom discourse. Our analysis revealed variations in teachers’ instructional visions and quality of instruction in their classrooms. In most cases, there was an alignment between teachers’ instructional vision and practices. We observed high quality instruction in terms of facilitating productive discussions and rigorous students’ thinking in the classroom of teachers with sophisticated instructional vision. Low instructional quality is observed in the classrooms of teachers with less articulate instructional vision of productive classroom discussion. We contend that exploring science teachers’ instructional vision and their instructional practices together can provide a powerful lens to identify the areas of improvement for promoting high-quality instruction in many science classrooms. Moreover, working towards the development of a shared vision of instruction by stakeholders and teachers can support enactment of high-quality science instruction.more » « less

Gibson, D. C.; Ochoa, M. N.; Christensen, R.; Cohen, J.; Crawford, D.; Graziano, K.; Langran, E.; Langub, L.; Rutledge, D.; Voogt, J. (Ed.)As computer science education standards are disseminated to K-12 school districts nationally, teacher education programs are left with the challenge of ensuring pre-service teachers are prepared to enter their first classroom with the skills and knowledge necessary to align instruction with the new standards. This paper examines the use of a learning intervention called “Block-Based Coding and Computational Thinking for Conceptual Mathematics” (B2C3Math) that aimed to help pre-service teachers majoring in early childhood and elementary education learn and apply computational thinking concepts to their elementary mathematics teaching. Ten pre-service teachers all at the same stage in their teacher preparation program participated in this convergent mixed-methods study. A focus of the research was placed on how participant’s computational thinking knowledge changed following the implementation of B2C3Math. Findings suggest that there were changes in the participants’ views of computational thinking application to elementary mathematics teaching following the implementation of B2C3Math. Implications for research and instructional practices using B2C3Math for teacher education are discussed.more » « less
