   Argumentation enables students to engage in real world scientific practices by rationalizing claims grounded in supporting evidence. Student engagement in scientific argumentation activates the negotiation process by which students develop and defend evidence-based claims. Little is known, however, on the intricate process and potential patterns of negotiation between students during scientific argumentation. The present study seeks to fill this gap by exploring how a group of university science education students negotiated when evaluating the relationship between lines of evidence and alternative explanatory models of a phenomena (i.e., climate change). This research, theoretically grounded in social constructionism, used Halliday's model of Systemic Functional Linguistics (SFL) within a discourse analysis framework. The authors analyzed transcripts of student conversations during a model-evidence link activity to gain insights into patterns of negotiation. An interpersonal analysis centering on mood and moves revealed students' ability to engage in the negotiation component of scientific argumentation to make assertions about relations between evidence and models. Effective collaboration resulting in group consensus of the relationship (categorized as supports, strongly supports, or contradicts) was facilitated by the use of interrogatives, modulation, and a balanced contribution between group members. Conversely, negotiation which did not reach consensus featured less contribution between group members. Conversely, negotiation which did not reach consensus featured less balanced discussion among group members, contained more interruptions, more conflict moves, and double polarity clauses.

2. A Professional Development Model to Integrate Computational Thinking Into Middle School Science Through Codesigned Storylines

   Biddy, Q.; Gendreau Chakarov, A.; Bush, J.; Hennessy Elliott, C.; Jacobs, J.; Recker, M.; Sumner, T.; Penuel, W. (March 2021, Contemporary issues in technology and teacher education)

   This article describes a professional development (PD) model, the CT-Integration Cycle, that supports teachers in learning to integrate computational thinking (CT) and computer science principles into their middle school science and STEM instruction. The PD model outlined here includes collaborative design (codesign; Voogt et al., 2015) of curricular units aligned with the Next Generation Science Standards (NGSS) that use programmable sensors. Specifically, teachers can develop or modify curricular materials to ensure a focus on coherent, student-driven instruction through the investigation of scientific phenomena that are relevant to students and integrate CT and sensor technology. Teachers can implement these storylines and collaboratively reflect on their instructional practices and student learning. Throughout this process, teachers may develop expertise in CT-integrated science instruction as they plan and use instructional practices aligned with the NGSS and foreground CT. This paper describes an examination of a group of five middle school teachers’ experiences during one iteration of the CT-Integration Cycle, including their learning, planning, implementation, and reflection on a unit they codesigned. Throughout their participation in the PD, the teachers expanded their capacity to engage deeply with CT practices and thoughtfully facilitated a CT-integrated unit with their students.

4. “Fake It Until You Make It”: Participation and Positioning of a Bilingual Latina Student in Mathematics and Computing

   https://doi.org/10.1177/01614681221104106  

   Celedón-Pattichis, Sylvia; Kussainova, Gulnara; LópezLeiva, Carlos A.; Pattichis, Marios S. (May 2022, Teachers College Record: The Voice of Scholarship in Education)

   Background/Context: After-school programs that focus on integrating computer programming and mathematics in authentic environments are seldomly accessible to students from culturally and linguistically diverse backgrounds, particularly bilingual Latina students in rural contexts. Providing a context that broadens Latina students’ participation in mathematics and computer programming requires educators to carefully examine how verbal and nonverbal language is used to interact and to position students as they learn new concepts in middle school. This is also an important stage for adolescents because they are likely to make decisions about their future careers in STEM. Having access to discourse and teaching practices that invite students to participate in mathematics and computer programming affords them opportunities to engage with these fields. Purpose/Focus of Study: This case study analyzes how small-group interactions mediated the positionings of Cindy, a bilingual Latina, as she learned binary numbers in an after-school program that integrated computer programming and mathematics (CPM). Setting: The Advancing Out-of-School Learning in Mathematics and Engineering (AOLME) program was held in a rural bilingual (Spanish and English) middle school in the Southwest. The after-school program was designed to provide experiences for primarily Latinx students to learn how to integrate mathematics with computer programming using Raspberry Pi and Python as a platform. Our case study explores how Cindy was positioned as she interacted with two undergraduate engineering students who served as facilitators while learning binary numbers with a group of three middle school students. Research Design: This single intrinsic case focused on exploring how small-group interactions among four students mediated Cindy’s positionings as she learned binary numbers through her participation in AOLME. Data sources included twelve 90-minute video sessions and Cindy’s journal and curriculum binder. Video logs were created, and transcripts were coded to describe verbal and nonverbal interactions among the facilitators and Cindy. Analysis of select episodes was conducted using systemic functional linguistics (SFL), specifically language modality, to identify how positioning took place. These episodes and positioning analysis describe how Cindy, with others, navigated the process of learning binary numbers under the stereotype that female students are not as good at mathematics as male students. Findings: From our analysis, three themes that emerged from the data portray Cindy’s experiences learning binary numbers. The major themes are: (1) Cindy’s struggle to reveal her understanding of binary numbers in a competitive context, (2) Cindy’s use of “fake it until you make it” to hide her cognitive dissonance, and (3) the use of Spanish and peers’ support to resolve Cindy’s understanding of binary numbers. The positioning patterns observed help us learn how, when Cindy’s bilingualism was viewed and promoted as an asset, this social context worked as a generative axis that addressed the challenges of learning binary numbers. The contrasting episodes highlight the facilitators’ productive teaching strategies and relations that nurtured Cindy’s social and intellectual participation in CPM. Conclusions/Recommendations: Cindy’s case demonstrates how the facilitator’s teaching, and participants’ interactions and discourse practices contributed to her qualitatively different positionings while she learned binary numbers, and how she persevered in this process. Analysis of communication acts supported our understanding of how Cindy’s positionings underpinned the discourse; how the facilitators’ and students’ discourse formed, shaped, or shifted Cindy’s positioning; and how discourse was larger than gender storylines that went beyond classroom interactions. Cindy’s case reveals the danger of placing students in “struggle” instead of a “productive struggle.” The findings illustrated that when Cindy was placed in struggle when confronting responding moves by the facilitator, her “safe” reaction was hiding and avoiding. In contrast, we also learned about the importance of empathetic, nurturing supporting responses that encourage students’ productive struggle to do better. We invite instructors to notice students’ hiding or avoiding and consider Cindy’s case. Furthermore, we recommend that teachers notice their choice of language because this is important in terms of positioning students. We also highlight Cindy’s agency as she chose to take up her friend’s suggestion to “fake it” rather than give up.

5. Digital Video Representations for Teaching Mathematics and Coding to Middle School Students

   https://doi.org/10.1109/DSP58604.2023.10167969  

   Pattichis, Marios S; Celedón-Pattichis, Sylvia; LópezLeiva, Carlos (July 2023, IEEE Xplore)

   We present an integrated mathematics and computer programming curriculum for teaching bilingual middle school students how to code using digital video representations. Building on the student's familiarity with digital video, we introduce them to number representations (e.g., binary and hexadecimals), NumPy arrays, coordinate systems, color, frames, and how to combine them into digital video content. The curriculum is fully integrated with middle school mathematics. Middle school students who completed the curriculum joined undergraduate students to co-teach the curriculum in a small group collaborative learning environment. We found evidence of successful implementations based on video recordings of student and facilitator interactions, attitude scales, student exit interviews, and samples of student work.
