   Engaging students in science learning that integrates disciplinary knowledge and practices such as computational thinking (CT) is a challenge that may represent unfamiliar territory for many teachers. CompHydro Baltimore is a collaborative partnership aimed at enacting Next Generation Science Standards (NGSS)–aligned instruction to support students in developing knowledge and practice reflective of the goals laid out in A Framework for K–12 Science Education (National Research Council 2012) “... that by the end of 12th grade, all students possess sufficient knowledge of science and engineering to engage in public discussion on related issues … and are careful consumers of scientific and technological information related to their everyday lives.” This article presents the results of a partnership that generated a new high school level curriculum and teacher professional development program that tackled the challenge of integrating hydrologic learning with computational thinking as applied to a real-world issue of flooding. CompHydro Baltimore produced Baltimore Floods, a six-lesson high school unit that builds students’ water literacy by engaging them in computational thinking (CT) and modeling practices as they learn about water system processes involved in urban flooding (See Computational Thinking and Associated Science Practices). CompHydro demonstrates that broad partnerships can address these challenges, bringing together the diverse expertise necessary to develop innovative CT-infused science curriculum materials and the teacher supports needed for successful implementation.

2. Characterizing Advantages and Challenges for Students Engaging in Computational Thinking and Systems Thinking Through Model Construction

   As human society advances, new scientific challenges are constantly emerging. The use of systems thinking (ST) and computational thinking (CT) can help elucidate these problems and bring us closer to a possible solution. The construction and use of models is one of the most widely used tools when trying to understand systems. In this paper, we examine four case studies of student pairs who were engaged in building and using system models in an NGSS-aligned project-based learning unit on chemical kinetics. Using a theoretical framework that describes how CT and ST practices are manifested in the modeling process we examine the progression of students’ models during their model revisions and explore strategies they employ to overcome modeling challenges they face. We discuss some suggestions to scaffold students’ progression in constructing computational system models and prepare teachers to support their students in engaging in CT and ST practices.

4. Developing instructional materials for English learners in the content areas: An illustration of traditional and contemporary materials in science education

   https://doi.org/10.1002/tesj.673  

   Grapin, Scott E. ; Haas, Alison ; Llosa, Lorena ; Lee, Okhee ( August 2022 , TESOL Journal)

   Research on TESOL materials development has focused primarily on instructional materials for contexts in which students are learning English separate from academic content (e.g., science, mathematics). This research could benefit from expansion given the increasing number of contexts in which students are learning content and English language simultaneously. In U.S. K–12 education specifically, a fast‐growing population of English learners (ELs) is expected to achieve academically rigorous content standards that reflect new ways of thinking about content, language, and their integration. Thus, developing instructional materials based on the standards has necessitated shifts from traditional to contemporary approaches. The purpose of this article is to illustrate how instructional materials for ELs in the content areas have evolved over time. After describing conceptual shifts in the fields of content area education and language education that underpin the evolution of instructional materials, the researchers present traditional and contemporary elementary science units. Then, they analyze the units in relation to key features of traditional and contemporary materials for ELs in the content areas. Finally, they discuss how materials development in content learning contexts could expand the scope of TESOL materials development by providing a fresh perspective on ongoing debates and tensions in this vibrant research area.

5. Preservice secondary science teachers’ understanding of academic language: Moving beyond “just the vocabulary”

   https://doi.org/10.1002/sce.21560  

   Meier, Valerie ; Aminger, Walter ; McLean, Mandy ; Carpenter, Stacey L. ; Moon, Sungmin ; Hough, Sarah ; Bianchini, Julie A. ( January 2020 , Science Education)

   To prepare preservice secondary science teachers to teach English learners (ELs), teacher education programs must provide sustained coursework and experiences in principles and strategies found effective in supporting ELs’ learning of science. In the context of a teacher education program recognized for its attention to ELs, we investigated seven preservice secondary science teachers’ understanding of academic language and of how to support EL students’ use of academic language. More specifically, over the course of their 13‐month program, we examined changes in (a) preservice teachers’ understanding of the three levels of academic language (i.e., lexical, or vocabulary; syntactic, or sentence; and discursive, or message) and (b) the types of instructional support they reported using at each level (e.g., peer collaboration at the discursive level). We also compared their understanding of academic language and instructional support both to their experienced cooperating teachers’ understanding and to their actual classroom practice. From qualitative analysis of data collected, we found that preservice teachers understood academic language as more than just vocabulary—as spanning lexical, syntactic, and discursive levels—although they reported implementing more types of supports at the lexical and discursive levels than at the syntactic level. We also found that preservice teacher participants’ understanding of academic language and instructional support resonated with that of their cooperating teachers and with their own classroom practice. We close with discussion of ways teacher education programs can deepen and broaden preservice secondary science teachers’ understanding of the role of academic language in ELs’ science learning
