Title: Using artificial intelligence teaching assistants to guide students in solar energy engineering design
Engineering projects, such as designing a solar farm that converts solar radiation shined on the Earth into electricity, engage students in addressing real-world challenges by learning and applying geoscience knowledge. To improve their designs, students benefit from frequent and informative feedback as they iterate. However, teacher attention may be limited or inadequate, both during COVID-19 and beyond. We present Aladdin, a web-based computer-aided design (CAD) platform for engineering design with a built-in artificial intelligence teaching assistant (AITA). We also present two curriculum units (Solar Energy Science and Solar Farm Design), where students explore the Sun-Earth relationship and optimize the energy output and yearly profit of a solar farm with the help of the AITA. We tested the software and curriculum units with over 100 students in two Midwestern high schools. Pre- and post-survey data showed improvements in understanding of science concepts and self-efficacy in engineering design. Pre-post analysis of design performance gains reveals that AI helped lower achievers more than higher achievers. Interviews revealed students’ values and preferences when receiving feedback. Our findings suggest that AITAs may be helpful as an additional feedback mechanism for geoscience and engineering education. Future efforts should focus on improving the usability of the software and providing multiple types of feedback to promote inclusive and equitable use of AI in education.  more » « less

  1. Abstract

    Recent calls for reform in K‐12 science education and the National Academy of Engineering's Grand Challenges for Engineering in the 21st Century emphasize improving science teaching, students' engagement, and learning. In this study, we designed and implemented a curriculum unit for sixth‐grade students (i = 1305). The curriculum unit integrated science and engineering content and practices to teach ecology, water pollution, and engineering design. We investigated the designed integrated STEM unit's effectiveness in students' science learning outcomes on pre‐, post‐, and delayed post‐assessments. We collected pre‐and post‐assessment data of students' science learning outcomes for both the baseline group (taught via existing district‐adopted curriculum) and an intervention group (taught with integrated life science and engineering curriculum). We used a quasi‐experimental research design and examined differences between baseline and intervention groups. We used ANCOVA to explore differences in students' learning in baseline and intervention groups. Furthermore, for students in the intervention group, we conducted repeated‐measures ANOVA to investigate knowledge retention. Our analyses also accounted for students' gender and People of Color (POC) status. We conducted multiple regression analyses to explore the relationship between students' gender, POC status, and their learning outcomes. The results indicated that the intervention group students performed significantly better than the students in the baseline group. The repeated measures ANOVA showed that students in the intervention group retained science knowledge after 8 weeks of instruction. Finally, the regression analysis for the baseline group showed that gender and POC status were not significant predictors of their post‐assessment scores. However, POC status was a significant predictor of post‐assessment scores and knowledge retention for the intervention group. Overall, this study provides valuable findings on how an integrated STEM curriculum designed with engineering design and practices improves students' science learning outcomes.

  2. As artificial intelligence (AI) technology becomes increasingly pervasive, it is critical that students recognize AI and how it can be used. There is little research exploring learning capabilities of elementary students and the pedagogical supports necessary to facilitate students’ learning. PrimaryAI was created as a 3rd-5th grade AI curriculum that utilizes problem-based and immersive learning within an authentic life science context through four units that cover machine learning, computer vision, AI planning, and AI ethics. The curriculum was implemented by two upper elementary teachers during Spring 2022. Based on pre-test/post-test results, students were able to conceptualize AI concepts related to machine learning and computer vision. Results showed no significant differences based on gender. Teachers indicated the curriculum engaged students and provided teachers with sufficient scaffolding to teach the content in their classrooms. Recommendations for future implementations include greater alignment between the AI and life science concepts, alterations to the immersive problem-based learning environment, and enhanced connections to local animal populations.

  3. Engineering education, with its focus on design and problem solving, has been shown to be fertile ground for encouraging students’ further development of their fundamental math and science skills in a way that they find relevant and engaging, and for promoting interest in STEM more broadly. To capitalize on these positive aspects of the engineering context, researchers developed, implemented, and studied a three-year engineering curriculum for grades 6 – 8 that utilizes the engineering design process and problem-based learning. In this semester-long elective course, students work through a series of design challenges within a given context (a carnival, airplanes and flight, and robotics, respectively, for 6th, 7th and 8th grades) and learn engineering content as well as practice fundamental math and science skills. This curriculum was developed and researched as part of an earlier project; in that work, course participation was linked with increased academic achievement on state-wide math and science assessments as well as heightened cognitive and behavioral engagement in STEM and science interest [1]. The current work seeks to replicate the findings of this earlier study in a different and larger school district while a) expanding the research foci to include teacher training and teachers’ pedagogical content knowledge and b) refining the curriculum materials including the teacher website and support materials. In this paper, we present the research strand focusing on the impact of the course on students’ attitudinal factors including engagement, science interest, and science and math anxiety. These factors were measured in each semester-long course using a pre-post survey design. Survey items are primarily from validated instruments and are similar to those used in prior research on this curriculum and its impact on students; prior research demonstrated good reliability, with alpha values ranging from 0.84 to 0.91 for each construct [1]. We compare students’ levels of engagement, science interest, and math and science anxiety at the pre and post time points to understand whether and how participating in the course influences their standing on these variables. . Open-ended survey items were used as a supplementary data source. The preliminary results from the first year of implementation (2022-2023 academic year) suggest that similar to the original study, there is an increase across some of the student constructs, including student engagement. This finding was also supported by engineering teachers’ input about student engagement in the classroom. As the study progresses into its planned 2nd and 3rd years of curriculum implementation, we will be able to further discern the extent to which multiple years of course enrollment might differentially impact the attitudinal factors of interest (i.e., dosage effects).

  4. As solar energy becomes increasingly affordable, many schools are considering installing new solar power systems. Can students contribute to the design, evaluation, and decision-making process in any way? Many students are familiar with solar power and energy, having researched solar energy on the internet, built solar cookers, inspected mini solar cells, gone on field trips to local solar farms, and so on. Well-informed and motivated, they are just one step away from taking responsibility for their own schools. In this article, we present Solarize Your School, an engineering project that gives students the opportunity to design and evaluate solar power solutions for their own schools. This STEM project requires students to learn and apply skills and practices related to solar energy and photovoltaic technology concepts, such as architectural measurement and modeling techniques, graphical interpretation and data analysis, budgeting and investing, scientific inquiry and engineering design, and collaboration and communication (see Next Generation Science Standards table, p. 47). Solarize Your School can be incorporated into environmental science, physical science, and engineering courses, and can be adapted to fit any curriculum scope and time frame. We suggest a 10-day sequence of learning activities. All the technologies and materials mentioned are freely available (see “On the web”).

  5. This paper analyzes students’ design solutions for an NGSS aligned earth sciences curriculum, the Playground Design Challenge (PDC), for upper-elementary school (grade 5 and 6) students.We present the underlying computational model and the user interface for generating design solutions for a school playground that has to meet cost, water runoff, and accessibility constraints. We use data from the pretest and posttest assessments and activity logs collected from a pilot study run in an elementary school to evaluate the effectiveness of the curriculum and investigate the relations between students’ behaviors and their learning performances. The results show that (1) the students’ scores significantly increased from pretest to posttest on engineering design assessments, and (2) students’ solution-generation and testing behaviors were indicative of the quality of their design solutions as well as their pre-post learning gains. In the future, tracking such behaviors online will allow us to provide adaptive scaffolds that help students improve on their engineering design solutions.
