This project evaluates if and how an intervention to design a K-12 STEM activity related to water chemistry impacts the innovation self-efficacy (ISE) of junior students enrolled in a required environmental engineering course. ISE is defined as having five behavioral components: questioning, observing, experimenting, idea networking, and associational thinking. In this course, the K-12 STEM activity is designed with a team of 3 to 5 students. The activity requires that the students develop an innovative activity that demonstrates environmental engineering concepts such as acid mine drainage, ocean acidification, and contaminant removal. The student projects are scaffolded throughout the 10 weeks via intermediate submissions and meetings with a K-12 STEM teacher and design mentors. In fall 2022 a pilot of the study was conducted and relied on a quantitative survey instrument that measured ISE, innovation interest (INT), and future innovative work interest (IW). Based on the preliminary findings of factor structure, item reliability, and face validity evaluated by two faculty and two undergraduate students, small changes were made to the quantitative assessment instrument. The revised survey was deployed in the fall of 2023 in a required junior-level test course and a senior-level control course. The senior-level control course consisted of students who took the junior-level course with the K-12 STEM activity in the previous year. In 2023 the K-12 STEM activity intervention also included additional scaffolding through the addition of 3 team-based and 2 individual reflections to understand the process of ISE formation. Pre-post comparisons of the quantitative survey items will be conducted for individual students in the test and control courses. Team and individual reflections from the test course will be analyzed after the course. Potential demographic differences in ISE will be explored. Potential team-level influences will also be evaluated to understand the impact of a team’s ISE score on enhancing an individual team member’s ISE gain. Focus groups and individual interviews with students who participated in the test course will take place in spring 2024. The ISE, INT, and IW of environmental engineering students will be further assessed in spring 2024 through the ISE survey in the environmental engineering capstone design course and a junior-level creativity and entrepreneurship design course. This assessment will compare two different learning experiences on ISE, INT, and IW, the K-12 STEM education activity design with a semester-long, group-based technical design experience. Preliminary results will be presented in the NSF Grantees Poster Session.

“Improving Student Experiences to Increase Student Engagement” (ISE-2) was awarded to Texas A&M University by the National Science Foundation, through EEC-Engineering Diversity Activities. ISE-2 is a faculty development program focused on reducing implicit bias and increasing active learning, with the goals of (a) increasing student engagement, success, and retention, and (b) ultimately seeing greater increases for underrepresented minority (URM), women, and first-generation students. Ten faculty teaching first- and second-year Engineering courses participated in the first cohort of ISE-2 in Summer 2017, which consisted of three workshops and six informal “coffee conversations”. At the conclusion of the workshops, each faculty was tasked with completing a teaching plan for the Fall 2017 semester, to incorporate the strategies and knowledge from ISE-2 into the courses they plan to teach. Focus groups with the ISE-2 faculty were conducted in Fall 2017 to obtain feedback about the faculty development program. Classroom observations were conducted using environmental scans and the Classroom Observation Protocol for Undergraduate STEM (COPUS)1 to assess the classroom climate of faculty in the experimental (ISE-2) and control groups. Student surveys were also administered to students who were taught by ISE-2 faculty and control group faculty to assess student engagement and classroom climate. While the project is still ongoing, feedback from faculty regarding ISE-2 have been positive.more » « less

Ion selective electrode (ISE) sensors have been broadly applied for real-time in situ monitoring of ion concentrations in water environments. However, ISE sensors suffer from critical problems, such as ionophore leaching, water-penetration, poor electrochemical stability, and resulting short life spans. In this study, a template-guided membrane matrix immobilization strategy was pursued as a novel ISE sensor fabrication methodology to enhance its sensing characteristics and longevity. Specifically, nano-porous anodized aluminum oxide (AAO) was used as the template for an NH 4 + -specific ISE sensor. A nano-porous nickel mesh eventually replaced the template and formed a compact, high-surface juncture with the NH 4 + ion-selective membrane matrix. The resulting template-guided nano-mesh ISE (TN-ISE) sensor displayed enhanced electrochemical stability ( i.e. , capacitance increased by 50%, reading drift reduced by 75%) when compared to a regular single-wall carbon nanotube (SW-CNT) ISE sensor used as the standard. The interface between the nano-mesh electrode and the ion selective membrane matrix was compact enough to prevent water influx at the electrode interface. This minimized ionophore leaching and increased the mechanical integrity of the TN-ISE sensor. The practical advantages of the novel sensor were validated via long-term (360 hours) tests in real wastewater, returning a small average error of 1.28% over this time. The results demonstrate the feasibility of the template-guided nano-mesh design and fabrication strategy toward ISEs for long-term continuous monitoring of water or wastewater quality.more » « less

“Improving Student Experiences to Increase Student Engagement” (ISE-2) was funded by the National Science Foundation, through EEC-Engineering Diversity Activities, at Texas A&M University. The grant activity focuses on a faculty development program for faculty who teach first- and second-year engineering courses. As part of the evaluation plan, classroom observations were conducted by the ISE-2 team to assess the classroom climate and teaching practices of ISE-2 faculty participants and non-participant faculty peers. Since Spring 2017, the team has conducted 78 classroom observations. The ISE-2 evaluation team had expert classroom observers train novice observers. The observer training sessions became the basis of this DIY Classroom Observation Toolkit, which is available for people who are interested in conducting systematic classroom observations but have limited experience with qualitative coding and observational research. The goal of the Toolkit is for these individuals to teach themselves using the Toolkit components: a) an annotated bibliography introducing articles that are helpful to understanding and conducting classroom observations, b) training videos teaching viewers to conduct classroom observations using a protocol, and c) a series of sample classroom videos and validation keys for each of the sample videos. This paper serves as a user manual for the Toolkit, which can be accessed at http://bit.ly/diyclassobtoolkit.more » « less

This research explored potential relationships between the innovation self-efficacy (ISE) of engineering students and their artistic creativity and life experiences revealed on an ice-breaker assignment. In a community-building assignment, students were directed to introduce themselves through cartoon monster drawings that communicated various personal attributes (such as the number of languages they speak, and the number of states visited). Previous research has found that multicultural experiences can shape feelings of self-efficacy concerning innovation and creativity. This pilot study was conducted in a single junior-level course for environmental engineering students. The innovation self-efficacy of participants was measured using a survey that included items from the Very Brief Innovation Self-Efficacy scale (ISE.6), the Innovation Interests scale (INI), and the Career Goals: Innovative Work scale (IW). The drawings were analyzed for Artistic Effort (AE) and Creative Work (CW) by engineering and art evaluators, respectively. The ISE survey results were compared with the AE and CW scores and the correlations with travel, gender, and multilingualism on creativity attributes were explored. A strong correlation between CW scores and AE scores was observed. A negative correlation between CW and ISE.6 was found. The CW scores were significantly different between female and male students, except for black/white shading in the cartoon drawings. There were no significant differences between the AE scores for female versus male students. Our results do not support the existence of a correlation between multilingualism and travel with artistic creativity and innovation self-efficacy attributes. Overall, we did not find that the students’ artistic creativity or life experiences revealed through the self-portrait activity provided insights into innovation attitudes.more » « less
