We explored the COVID-19 pandemic as a context for learning about the role of science in a global health crisis. In spring 2020, at the beginning of the first pandemic-related lockdown, we worked with a high school teacher to design and implement a unit on human brain and behavior science. The unit guided her 17 students in creating studies that explored personally relevant questions about the pandemic to contribute to a citizen science platform. Pre-/postsurveys, student artifacts, and student and teacher interviews showed increases in students' fascination with science--a driver of engagement and career preference--and sense of agency as citizen scientists. Students approached science as a tool for addressing their pandemic-related concerns but were hampered by the challenges of remote schooling. These findings highlight both the opportunities of learning from a global crisis, and the need to consider how that crisis is still affecting learners.

Peer ideas can be valuable contributions to scientific inquiry. Divergent peer ideas can enrich students' thinking and encourage curiosity. Meanwhile, similar peer ideas can promote convergent thinking that can reinforce understanding. However, students need guidance in critically evaluating peer ideas in relation to their own, and in recognizing the influence of peers' ideas. Guided by the Knowledge Integration framework, we explore whether students' perceptions of the impact of peers' ideas align with the revisions made to their written explanations. In a technology-rich, classroom-based inquiry unit on cancer cell division, Grade 7 students (N = 144) investigated the effects of different cancer treatments on cell division, and developed explanations for a recommended treatment. We prompted one group of students to visit a class repository to seek peer ideas similar to their own, and another to seek ideas different from their own. Both groups then revised their recommendations. Based on analyses of students' reflections, initial and revised explanations, and pre and posttests, we found that students prompted to seek divergent ideas perceived peers' ideas to be more impactful, even though both groups of students revised at the same rate and made similar pre to posttest gains. This study suggests a need to attend to students' perceptions of the roles of their peers, particularly in environments designed to reflect authentic processes of the social construction of scientific knowledge.

Citizen science programs offer opportunities for K-12 students to engage in authentic science inquiry. However, these programs often fall short of including learners as agents in the entire process, and thus contrast with the growing open science movement within scientific communities. Notably, study ideation and peer review, which are central to the making of science, are typically reserved for professional scientists. This study describes the implementation of an open science curriculum that engages high school students in a full cycle of scientific inquiry. We explored the focus and quality of students' study designs and peer reviews, and their perceptions of open science based on their participation in the program. Specifically, we implemented a human brain and behavior citizen science unit in 6 classrooms across 3 high schools. After learning about open science and citizen science, students (N = 104) participated in scientist-initiated research studies, and then collaboratively proposed their own studies to investigate personally interesting questions about human behavior and the brain. Students then peer reviewed proposals of students from other schools. Based on a qualitative and quantitative analysis of students' artifacts created in-unit and on a pre and posttest, we describe their interests, abilities, and self-reported experiences with study design and peer review. Our findings suggest that participation in open science in a human brain and behavior research context can engage students with critical aspects of experiment design, as well as with issues that are unique to human subjects research, such as research ethics. Meanwhile, the quality of students' study designs and reviews changed in notable, but mixed, ways: While students improved in justifying the importance of research studies, they did not improve in their abilities to align methods to their research questions. In terms of peer review, students generally reported that their peers' feedback was helpful, but our analysis showed that student reviewers struggled to articulate concrete recommendations for improvement. In light of these findings, we discuss the need for curricula that support the development of research and review abilities by building on students' interests, while also guiding students in transferring these abilities across a range of research foci.

Transmedia design, which involves extending a narrative from one medium to another, offers a context for potentially rich, interdisciplinary learning. We explored these opportunities by creating a week-long workshop to guide 7th-grade student teams in designing games based on comic books about viruses. This design case describes the framework and rationale behind our design choices. It illustrates our experiences by drawing on field note observations and audio recordings, student-generated design artifacts, student and facilitator interviews, and planning documentation from across two iterations of the workshop. We reflect on our experiences in attempting to balance (1) the dual focus of the workshop on science learning and game design through our choices of comic and game genres; and (2) the ability for students to be both autonomous and to receive necessary guidance through our enforcement of design constraints and interdependent team roles. We also reflect on the contextual factors that mediated our work, including students' existing interests and peer relations, their teachers' involvement, and our own team's shifting expertise as membership changed from one iteration to the next. Among other things, our experiences highlight the importance of designing to allow for change, particularly as learning through collaborative transmedia game design can occur in unanticipated ways. Finally, we reflect on plans for future iterations of this workshop.

Science inquiry challenges students to synthesize various ideas about complex phenomena into coherent explanations. It also challenges teachers, who must guide their diverse students' developing understanding during student-paced investigations. We describe the Idea Manager, a suite of web-based, curriculum-integrated tools that (a) guides students' knowledge integration as they generate, distinguish, and reconcile their ideas; and (b) provides means for teachers to monitor learning over the course of technology-enhanced science inquiry units. With the Idea Manager tool, students document short, text-based ideas, tag and sort them along various attributes, and exchange them with classmates. At culminating points of their investigations, students graphically organize their ideas to prepare written scientific explanations. Meanwhile, logs of idea entries, revisions, and meta-data inform teachers' and researchers' decisions about instruction and design. This paper offers an account of the design moves made in refining the Idea Manager, and highlights the importance of teacher-researcher partnerships and classroom implementations. Through designers' artifacts, classroom research findings, and teachers' and researchers' reflections, we illustrate the tool's origins; our strategies for testing new features and eliciting stakeholders' feedback, and how middle and high school classroom implementations inform the tool's continued iterations. Based on learning theory and on our own 40+ collective years of classroom teaching experience, we explain our design decisions and describe how new features and patterns for the tool's use emerged from a community of researchers. Finally, we reflect on the process of iteration that advances both theory and design, and on the value of pedagogically-driven technology design.

Inquiry instruction often neglects graphing. It gives students few opportunities to develop the knowledge and skills necessary to take advantage of graphs, and which are called for by current science education standards. Yet, it is not well known how to support graphing skills, particularly within middle school science inquiry contexts. Using qualitative graphs is a promising, but underexplored approach. In contrast to quantitative graphs, which can lead students to focus too narrowly on the mechanics of plotting points, qualitative graphs can encourage students to relate graphical representations to their conceptual meaning. Guided by the Knowledge Integration framework, which recognizes and guides students in integrating their diverse ideas about science, we incorporated qualitative graphing activities into a seventh grade web-based inquiry unit about cell division and cancer treatment. In Study 1, we characterized the kinds of graphs students generated in terms of their integration of graphical and scientific knowledge. We also found that students (n = 30) using the unit made significant learning gains based on their pretest to post-test scores. In Study 2, we compared students' performance in two versions of the same unit: One that had students construct, and second that had them critique qualitative graphs. Results showed that both activities had distinct benefits, and improved students' (n = 117) integrated understanding of graphs and science. Specifically, critiquing graphs helped students improve their scientific explanations within the unit, while constructing graphs led students to link key science ideas within both their in-unit and post-unit explanations. We discuss the relative affordances and constraints of critique and construction activities, and observe students' common misunderstandings of graphs. In all, this study offers a critical exploration of how to design instruction that simultaneously supports students' science and graph understanding within complex inquiry contexts.

Teachers' involvement in curriculum design is essential for sustaining the relevance of technology-enhanced learning materials. Customizing--making small adjustments to tailor given materials to particular situations and settings--is one design activity in which busy teachers can feasibly engage. Research indicates that customizations based in evidence from student work lead to improved learning outcomes. In this paper, we examine the customizations of four middle and high school teachers during their enactments of web-based inquiry science units. We examine how specific technology features afforded their customizations by providing tools for making adaptations and by making student work available as evidence for those adaptations. Cases built from classroom video and field note observations, interviews, and teachers' curriculum artifacts, revealed three kinds of customizations: (a) devising timely instructional interventions to provide individualized guidance; (b) planning activities and adjusting milestones to align with students' progress; (c) modifying existing materials to better integrate content into overall curriculum plans; and (d) incorporating scaffolds to better address students' needs. We also identified three technology features that supported teachers' customizations: (1) a system that logs student work for teachers' inspection; (2) tools for conducting dynamic, formative assessment; and (3) an authoring environment that supports the re-design of units at multiple levels of granularity. We end by suggesting design principles for curriculum materials that support teachers' customizations, as well as future directions for technology that would enhance teachers' participation as designers.

Despite many years of efforts to communicate new scientific knowledge to the public, surveys continue to suggest that many people remain uninformed about current scientific research (Miller, 2001; Miller, 2004) and fail to recognize how it can be relevant to their lives. There is continued need for investigation on improving methods for engaging people with scientific knowledge. Our goal is to contribute to efforts to disseminate emerging science knowledge by focusing on a particularly relevant science topic, viruses, and a critical age group, teenagers. Prior research suggests that many teenagers have low science achievement and/or low interest in science (Gonzalez, et al., 2008), and thus can be characterized as having low science identity. How can educators engage all teenagers, even those with low science identity? Guided by identity theory and a model of interest development, we assess one possible, unconventional approach -- using comic books to convey science information. This study focuses on viruses as scientific content. First we review why knowledge of viruses is important content to disseminate, and provide evidence that the general public's knowledge of viruses is limited. After discussing the relationship between interest and achievement in science, we describe the rationale for using comics as an educational format. We next summarize key concepts in identity theory and a model of interest development that justify comparing comic and essay formats for disseminating scientific information. We describe the study, results, and implications of our findings for efforts to engage a broad spectrum of youth with science.
