    Computational thinking (CT) is ubiquitous in modern science, yet rarely integrated at the elementary school level. Moreover, access to computer science education at the PK-12 level is inequitably distributed. We believe that access to CT must be available earlier and implemented with the support of an equitable pedagogical framework. Our poster will describe our Accessible Computational Thinking (ACT) research project exploring professional development with elementary teachers on integrating computational thinking with Culturally Responsive Teaching practices.

    We used Natural Language Processing (NLP) to design an adaptive computer dialogue that engages students in a conversation to reflect on and revise their written explanations of a science dilemma. We study the accuracy of the NLP idea detection. We analyze how 98 12-13 year-olds interacted with the dialogue as a part of a Diagnostic Inventory. We study students’ initial and revised science explanations along with their logged responses to the dialogue. The dialogue led to a high rate of student revision compared to prior studies of adaptive guidance. The adaptive prompt encouraged students to reflect on prior experiences, to consider new variables, and to raise scientific questions. Students incorporated these new ideas when revising their initial explanations. We discuss how these adaptive dialogues can strengthen science instruction.

    This work-in-progress poster reports on the development process of a virtual environment to support embodied cognition about the scale of scientific entities from subatomic particles to galaxies. Research shows that learners struggle to comprehend the sizes of entities beyond human scale. In order to determine specific entities to use in the virtual environment, a document analysis of US K-undergraduate science education standards was undertaken. Entities, categories of entities, and ranges of sizes were identified.

    Higher education institutions around the globe have increasingly made the commitment to diversity. Instructors play an integral role in creating inclusive learning environments. Guided by sociopolitical perspectives on learning, we ask: How do higher education instructors conceptualize diversity? How do these conceptions inform curriculum and instruction? Interview data from 30 instructors teaching at minority-serving institutions in the United States revealed three distinct conceptions of diversity defined by variations in five aspects: student identities, intelligence mindset, pedagogical motivation, learning environment, and legitimized membership. The essentialist conception is based on students having inherently determinate traits described by preexisting universal categories. The functionalist conception differentiates students by academic performance. The existentialist conception acknowledges that students have unique experiences that impact the learning process. Our results indicate that while instructors acknowledge different student features and have varying understanding for why diversity is important, some conceptions of diversity do not necessarily suggest an inclusive culture.

    We use natural language processing (NLP) to train an automated scoring model to assess students’ reasoning on how to slow climate change. We use the insights from scoring over 1000 explanations to design a knowledge integration intervention and test it in three classrooms. The intervention supported students to distinguish relevant evidence, improving connections between ideas in a revised explanation. We discuss next steps for using the NLP model to support teachers and students in classrooms.

    From a design-based research study investigating rural families’ science learning with mobile devices, we share findings related to the intergenerational exploration of geological time concepts at a children’s garden at a university arboretum. The team developed a mobile augmented reality app, Time Explorers, focused on how millions of years of rock-water interactions shaped Appalachia. Data are recorded videos of app usage and interviews from 17 families (51 people); videos were transcribed, coded, and developed into qualitative case studies. We present results related to design elements that supported sensory engagement (e.g., observation, touch) through AR visualizations related to geological history. This analysis contributes to the literature on informal learning environments, theory related to learning-on- the-move, and the role of sensory engagement with AR experiences in outdoor learning.

    Immersive AR technologies can support students’ learning processes and deep engagement with outdoor science pursuits, yet few studies explore these technologies with out-of-school learners. We analyze how immersive AR features built into an outdoor-based mobile app shaped nine families’ learning experiences as they explored pollinator habitats. Preliminary findings revealed that immersive AR scanning tools built into the Pollinator Explorers app guided families’ observational practices of real-world objects through virtual overlays representing pollinator habitats.
