ABSTRACT
The Discovery Research K-12 program (DRK-12) seeks to significantly enhance the learning and teaching of science, technology, engineering and mathematics (STEM) by preK-12 students and teachers, through research and development of innovative resources, models and tools (RMTs). Projects in the DRK-12 program build on fundamental research in STEM education and prior research and development efforts that provide theoretical and empirical justification for proposed projects.
In this project, SmartCAD: Guiding Engineering Design with Science Simulations, the Concord Consortium (lead), Purdue University, and the University of Virginia investigate how real time formative feedback can be automatically composed from the results of computational analysis of student design artifacts and processes with the envisioned SmartCAD software. Through automatic feedback based on visual analytic science simulations, SmartCAD is able to guide every student at a fine-grained level, allowing teachers to focus on high-level instruction. Considering the ubiquity of computer-aided design (CAD) software in the workplace and their diffusion into precollege classrooms, this research provides timely results that could motivate the development of an entire genre of CAD-based learning environments and materials to accelerate and scale up K-12 engineering education. The project conducts design-based research on SmartCAD, which supports secondary science and engineering with three embedded computational engines capable of simulating the mechanical, thermal, and solar performance of the built environment. These engines allow SmartCAD to analyze student design artifacts on a scientific basis and provide automatic formative feedback in forms such as numbers, graphs, and visualizations to guide student design processes on an ongoing basis.
The research hypothesis is that appropriate applications of SmartCAD in the classroom results in three learning outcomes: 1) Science knowledge gains as indicated by a deeper understanding of the involved science concepts and their integration at the completion of a design project; 2) Design competency gains as indicated by the increase of iterations, informed design decisions, and systems thinking over time; and 3) Design performance improvements as indicated by a greater chance to succeed in designing a product that meets all the specifications within a given period of time. While measuring these learning outcomes, this project also probes two research questions: 1) What types of feedback from simulations to students are effective in helping them attain the outcomes? and 2) Under what conditions do these types of feedback help students attain the outcomes? To test the research hypothesis and answer the research questions, this project develops three curriculum modules based on the Learning by Design (LBD) Framework to support three selected design challenges: Solar Farms, Green Homes, and Quake-Proof Bridges. This integration of SmartCAD and LBD situate the research in the LBD context and shed light on how SmartCAD can be used to enhance established pedagogical models such as LBD. Research instruments include knowledge integration assessments, data mining, embedded assessments, classroom observations, participant interviews, and student questionnaires. This research is carried out in Indiana, Massachusetts, and Virginia simultaneously, involving more than 2,000 secondary students at a number of socioeconomically diverse schools. Professional development workshops are provided to familiarize teachers with SmartCAD materials and implementation strategies prior to the field tests. An external Critical Review Committee consisting of five engineering education researchers and practitioners oversee and evaluate this project formatively and summative. Project materials and results are disseminated through publications, presentations, partnerships, and the Internet.

PROJECT OUTCOMES REPORT

A common need in project-based engineering education is to provide students timely feedback while they are solving design problems. But it is unrealistic to expect teachers to monitor and mentor each individual student in the classroom all the time. The lack of personalized formative feedback in design processes limits students' ability to iterate through many possibilities to find optimal solutions, undercutting the promise of engineering education in teaching students to become creative designers. This project investigated how science simulations can be embedded in engineering design tools to guide students in solving design challenges in real time. To support the research, the project has developed an open-source, Web-based CAD software tool named as Aladdin (https://intofuture.org/aladdin.html), which supports architectural engineering and renewable energy engineering. With Aladdin, students can draw a 3D model, set the properties of each element of the model, and then analyze its performance -- all within a single system. Based on the analysis results, students can then decide their next steps. Furthermore, using artificial intelligence, Aladdin can provide students with automatic assessment of their designs by evaluating the extent to which a design needs to be improved. Based on Aladdin, the project has conducted empirical research in collaboration with middle and high schools in multiple states, involving hundreds of students from diverse socioeconomic backgrounds. Pre/post-test results show learning gains in science concepts. Learning analytics was used to reveal self-regulation behaviors of students from the process data collected by the software through even logging that captures students' fine-grained interactions with the software.
