Background To succeed in engineering careers, students must be able to create and apply models to certain problems. The different types of models include physical, mathematical, computational, graphical, and financial, which are used both in academics, research, and industry. However, many students struggle to define, create, and apply relevant models in their engineering courses. Purpose (Research Questions) The research questions investigated in this study are: (1) What types of models do engineering students identify before and after completing a first-year engineering course? (2) How do students’ responses compare across different courses (a graphical communications course - EGR 120 and a programming course - EGR 115), and sections? Design/Methods The data used for this study were collected in two introductory first-year engineering courses offered during Fall 2019, EGR 115 and EGR 120. Students’ responses to a survey about modeling were qualitatively analyzed. The survey was given at the beginning and the end of the courses. The data analyzed consisted of 560 pre and post surveys for EGR 115 and 384 pre and post surveys for EGR 120. Results Once the analysis is complete, we are hoping to find that the students can better define and apply models in their engineering courses after they have completed the EGR 115 and/or EGR 120 courses.

Change in student understanding of modeling during first-year engineering courses
All engineers must be able to apply and create models to be effective problem solvers, critical thinkers, and innovative designers. To be more successful in their studies and careers, students need a foundational knowledge about models. An adaptable approach can help students develop their modeling skills across a variety of modeling types, including physical models, mathematical models, logical models, and computational models. Physical models (e.g., prototypes) are the most common type of models that engineering students identify and discuss during the design process. There is a need to explicitly focus on varying types of models, model application, and model development in the engineering curriculum, especially on mathematical and computational models. This NSF project proposes two approaches to creating a holistic modeling environment for learning at two universities. These universities require different levels of revision to the existing first-year engineering courses or programs. The proposed approaches change to a unified language and discussion around modeling with the intent of contextualizing modeling as a fundamental tool within engineering. To evaluate student learning on modeling in engineering, we conducted pre and post surveys across three different first-year engineering courses at these two universities with different student demographics. The comparison between the pre and post surveys highlighted student learning on engineering modeling based on different teaching and curriculum change approaches.

null (Ed.)To succeed in engineering careers, students must be able to create and apply models to certain problems. The different types of modeling skills include physical, mathematical, computational, graphing, and financial. However, many students struggle to define and form relevant models in their engineering courses. We are hoping that the students are able to better define and apply models in their engineering courses after they have completed the MATLAB and/or CATIA courses. We also are hoping to see a difference in model identification between the MATLAB and CATIA courses. All students in the MATLAB and CATIA courses must be able to understand and create models in order to solve problems and think critically in engineering. Students need foundational knowledge about basic modeling skills that will be effective in their course. The goal is for students to create an approach to help them solve problems logically and apply different modeling skills.more » « less

As part of the e4usa curriculum, a MATLAB model has been developed and implemented in order to cultivate engineering and computational thinking skills in high school students. The MATLAB model uses a live script that allows students to interact with sliders and dropdown menus to change parameters on a water filtration model. With computational skills increasingly in demand, the literature suggests that adding computational thinking and coding skills as a new form of literacy is crucial for preparing future engineering professionals. Additionally, to ensure that students are better prepared by the time they reach their post-secondary studies, early exposure to computational thinking skills has valuable implications. In this fundamental paper, we describe outcomes resulting from students' interactions with MATLAB in e4usa. The mathematical model allows the students to analyze the effects of different filtration materials, impurities to be removed, length of the water filter, and the space between particles in their filtration material. Using at first a mathematical model rather than testing physical materials will allow them to learn more about their potential filtration materials so that they may make more informed decisions about which filtration materials they want to select for their design and use in the prototype that they build and test. With that said, we focus on student outcomes in this design activity. We hypothesize that this modeling activity prior to design may reduce the time spent in physical testing as well as the volume of materials consumed. Additionally, we are inquisitive about the impact that it has on the subsequent design activities compared to previous semesters where this lesson was taught, where it was observed that students spend a considerable amount of time trying out different materials. As part of our data, we have collected teacher data from surveys, pre and post-responses about their expectations, attitudes, and perceived value of implementing the MATLAB model in their classrooms, class observation data from at least two schools where we noted the interactions between the teachers and students, and teacher and student focus groups at the end of the semester where we expect to collect richer data from these two groups that will allow us to triangulate data collected from surveys and classroom observations.more » « less

Despite national efforts in increasing representation of minority students in STEM disciplines, disparities prevail. Hispanics account for 17.4% of the U.S. population, and nearly 20% of the youth population (21 years and below) in the U.S. is Hispanic, yet they account for just 7% of the STEM workforce. To tackle these challenges, the National Science Foundation (NSF) has granted a 5-year project – ASSURE-US, that seeks to improve undergraduate education in Engineering and Computer Science (ECS) at California State University, Fullerton. The project seeks to advance student success during the first two years of college for ECS students. Towards that goal, the project incorporates a very diverse set of approaches, such as socio-cultural and academic interventions. Multiple strategies including developing early intervention strategies in gateway STEM courses, creating a nurturing faculty-student interaction and collaborative learning environment, providing relevant, contextual-based learning experiences, integrating project-based learning with engineering design in lower-division courses, exposing lower-division students to research to sustain student interests, and helping students develop career-readiness skills. The project also seeks to develop an understanding of the personal, social, cognitive, and contextual factors contributing to student persistence in STEM learning that can be used by STEM faculty to improve their pedagogical and student-interaction approaches. This paper summarizes the major approaches the ASSURE-US project plans to implement to reduce the achievement gap and motivate ECS students to remain in the program. Preliminary findings from the first-year implementation of the project including pre- and post- data were collected and analyzed from about one hundred freshmen and sophomore ECS students regarding their academic experience in lower-division classes and their feedback for various social support events held by the ASSURE-US project during the academic year 2018-19. The preliminary results obtained during the first year of ASSURE-US project suggests that among the different ASSURE-US activities implemented in the first year, both the informal faculty-student interactions and summer research experiences helped students commit more to their major during their lower-division years. The pre-post surveys also show improvements in terms of awareness among ASSURE-US students for obtaining academic support services, understanding career options and pathways, and obtaining personal counseling services.more » « less
