Engineering

The Design Talk project aims to to enact and characterize multiple types of whole-class engineering design conversations in first-grade through sixth-grade classrooms. The Design Talk resource library will enable educators and curriculum developers to see distinctly different kinds of classroom conversations that make engineering an activity in which all students engage in productive sense-making and ethical decision-making. This approach to classroom discourse foregrounds a perspective of care as central to engineering design work.

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.

We designed a learning approach and associated curricular program that builds from the 5Es (Bybee) model to harness STEM learning toward the engineered design of solutions (phases: Engage, Explore, Explain. Engineer, and Educate). Curricular activities emphasized design features that promote interest and motivation (e.g., choice, appropriately challenging, personal relevance). Research results demonstrated significant learning gains overall and on subparts (e.g., arguments). Teacher and student interviews articulated sustained engagement and motivation.

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.

Young children naturally engage in science and engineering practices (SEPs) through play in sophisticated ways. We are developing professional learning modules for early childhood and elementary educators to recognize and deepen children's engagement with SEPs while leveraging SciEPOP, as a professional online learning tool. This poster explores the design of these modules to engage educators in recognizing when children are engaging in SEPs through play and consider approaches to deepening and extending such engagements.

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.
