Title: Anchor Code: Modularity as Evidence for Conceptual Learning and Computational Practices of Students Using a Code-First Environment
In response to increasing calls to include computational thinking (CT) in K-12 education, some researchers have argued for integrating science learning and CT. In that vein, this paper investigates conceptual learning and computational practices through the use of a code-first modeling environment called Frog Pond in a middle school classroom. The environment was designed to enable learners to explore models of evolutionary shifts through domain-specific agent-based visual programming. It was implemented as a curricular unit in seventh grade science class. We analyzed video and log data of two contrasting student pairs. This paper presents one of our findings: Development of modular core functional code-units or what we call anchor code. Anchor code is a body of code that creates a stable base from which further explorations take place. We argue that anchor code is evidence for conceptual learning and computational practices.  more » « less

  1. Despite the increasing attention to infusing CT into middle and high school content area classrooms, there is a lack of information about the most effective practices and models to support teachers in their efforts to integrate disciplinary content and CT principles. To address this need, this paper proposes the Code, Connect and Create (3C) professional development (PD) model, which was designed to support middle and high school content area teachers in infusing computational thinking into their classrooms. To evaluate the model, we analyzed quantitative and qualitative data collected from Infusing Computing PD workshops designed for in-service science, math, English language arts, and social studies teachers located in two Southeastern states. Drawing on findings from our analysis of teacher-created learning segments, surveys, and interviews, we argue that the 3C professional development model supported shifts in teacher understandings of the role of computational thinking in content area classrooms, as well as their self-efficacy and beliefs regarding CT integration into disciplinary content. We conclude by offering implications for the use of this model to increase teacher and student access to computational thinking practices in middle and high school classrooms.

  2. Recent reform initiatives in STEM disciplines inspired the development and implementation of integrated STEM approaches to science teaching and learning. Integrated STEM as an approach to science teaching and learning leverages engineering principles and practices to situate learning in an authentic and meaningful science learning environment. However, integrated STEM curricular activities can be cognitively challenging for learners, so it is essential that teachers employ scaffolding techniques to facilitate student understanding of the connections between concepts and practices of the integrated disciplines. In this paper, we describe Legitimation Code Theory as an analytical framework and provide an analysis of semantic patterns of an integrated STEM unit (written discourse) and a middle school teacher’s enactment of that unit (oral discourse). Specifically, this analysis focused on the semantic gravity (SG), or level of context dependency, of the activities and dialogue present throughout the unit. Creating a semantic profile offers a snapshot of how abstract (weaker SG) or how specific (stronger SG) a concept is presented in relation to other concepts. Curriculum that presents ideas through the formation of semantic waves, or oscillations between areas of stronger and weaker semantic gravity, is linked to enhanced learning of complex ideas. The results of this study identify the areas in the curriculum unit and instruction that enable or constrain knowledge-building within the science classroom. We posit that the Legitimation Code Theory is a useful tool for developing and examining integrated STEM curriculum and its implementation.

  3. Researchers and practitioners have demonstrated various benefits of introducing computational thinking (CT) through music com- position coding. While researchers have studied the impacts on participant attitudes towards CT and their learning of CT concepts, more case studies are needed on both learning CT concepts as well as CT practices, i.e., the processes of constructing music coding projects. This paper presents a case study of middle schoolers in an informal learning environment focused on integrating music composition with coding in TunePad. Specifically, we collected and analyzed logs of coding events, final code products, and surveys to explore both CT concept use and CT practices exhibited by the par- ticipants as they completed open-ended music coding activities to create their own melodies with specific music and CT requirements and recommendations

  4. C2STEM is a web-based learning environment founded on a novel paradigm that combines block-structured, visual programming with the concept of domain specific modeling languages (DSMLs) to promote the synergistic learning of discipline-specific and computational thinking (CT) concepts and practices. Our design-based, collaborative learning environment aims to provide students in K-12 classrooms with immersive experiences in CT through computational modeling in realistic scenarios (e.g., building models of scientific phenomena). The goal is to increase student engagement and include inclusive opportunities for developing key computational skills needed for the 21st century workforce. Research implementations that include a semester-long high school physics classroom study have demonstrated the effectiveness of our approach in supporting synergistic learning of STEM and CS/CT concepts and practices, especially when compared to a traditional classroom approach. This technology demonstration will showcase our CS+X (X = physics, marine biology, or earth science) learning environment and associated curricula. Participants can engage in our design process and learn how to develop curricular modules that cover STEM and CS/CT concepts and practices. Our work is supported by an NSF STEM+C grant and involves a multi-institutional team comprising Vanderbilt University, SRI International, Looking Glass Ventures, Stanford University, Salem State University, and ETR. More information, including example computational modeling tasks, can be found at C2STEM.org.

  5. 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.
