The rock cycle is rarely taught in conjunction with plate tectonics. The method of studying images of rock outcrops is not enough to explain how rocks are formed and transformed over time. This project has developed a simulation for students to investigate the formation and evolution of rock sequences created under specific tectonic conditions. By bridging the tectonic system and the rock genesis system, students engage in scientific practices that are authentic to how geoscientists’ work.

Computational thinking (CT) is critical in all STEM fields, but it is typically not integrated in STEM courses beyond computer science. To address this gap, our project team is developing a month-long CT-intensive biology unit, where students learn to program a robotic gripper to respond to changes in their electrical muscle activity. This provides a novel, interdisciplinary, and real-world context for students to develop their CT.

EPK-2 is designing and testing a model of PreK-2nd grade teacher professional learning to address computational thinking. The focus is teachers’ generative development in CT as informed by collaborative, inquiry-based learning. The goal is to help teachers and schools build computational thinking pathways beginning with students’ earliest years. Research questions explore factors mediating PreK-2nd grade teachers’ learning and implementation of computational thinking in their classrooms.

“Dimensions of Success: Transforming Quality Assessment in Middle School Science and Engineering” aims to update and expand the Dimensions of Success (DoS) quality observation tool (created for informal science learning settings under NSF Award #1008591) to middle school science and engineering classrooms. This project will create a sustainable and scalable system of support for teachers as they 1) implement current science and engineering standards, and 2) create classroom cultures that are equitable and inclusive.

In this project, we engaged elementary (grades K-5) pre-service teachers (PSTs) as facilitators in a family technology program called Family Creative Learning, embedded in the Denver Public Library makerspace network. We studied PSTs’ computational thinking and facilitation practices and its impact on children's learning across informal and classroom settings where pre-service teachers concurrently conduct their field work. The project team will develop research-based resources, tools, and activities that help to cultivate these key facilitation practices.

This project uses over 2000 integrated STEM classroom videos to design and validate the STEM Observation Protocol (STEM-OP) for use in classrooms where integrated STEM is taking place. The STEM-OP is a valid and reliable instrument for use in a variety of educational contexts and research. The STEM-OP and associated training materials are available for use by stakeholders such as K-12 teachers, district administrators, teacher educators, and educational researchers through an online platform.

MindHive is an open science, citizen science initiative that supports authentic human brain and behavioral science inquiry experiences for high school learners, educators, and their communities. The online platform features a suite of tools that enable learners’ research activities, paired with teaching materials. The program s co-designed by a team of educational researchers, teachers, scientists, UX researchers, and developers; and supports collaboration between students from schools across the country, professional scientists, and community organizers.

In this project, we investigate haptic systems that are readily available for rendering visual STEM content through sight, sound, and touch. We use combinations of visual display, text-to-speech, vibrations, and the movement of one’s hands for interacting with STEM content (such as charts and graphs in math and science-based simulations) multimodally on touchscreens. Our investigations extend into "smart" tangible manipulatives that pair with interactive PhET simulations and enable rich kinesthetic manipulation of on-screen content through touch.

We present a framework for using scenario-based assessments (SBAs) to measure middle school students' ability to formulate written arguments around socio-scientific issues. We present data showing both the current strengths and limitations of these SBAs. We also present data which shows that, through the process of writing over a 2-week time span, the students showed significant improvements in their ability to make a claim, locate evidence, use reasoning, and use scientific vocabulary in their arguments.
