   The association between student motivation and learning, and changes in motivation across a course, were evaluated for students enrolled in one-semester foundation-level inorganic chemistry courses at multiple postsecondary institutions across the United States. The Academic Motivation Scale for Chemistry (AMS-Chemistry) and the Foundations of Inorganic Chemistry American Chemical Society Exam (i.e., a content knowledge measure) were used in this study. Evidence of validity, reliability, and longitudinal measurement invariance for data obtained from the AMS-Chemistry instrument with this population were found using methodologies appropriate for ordinal, non-parametric data. Positive and significant associations between intrinsic motivation measures and academic performance corroborate theoretical and empirical investigations; however, a lack of pre/post changes in motivation suggest that motivation may be less malleable in courses primarily populated by chemistry majors. Implications for inorganic chemistry instructors include paths for incorporating engaging pedagogies known to promote intrinsic motivation and methods for incorporating affect measures into assessment practices. Implications for researchers include a need for more work that disaggregates chemistry majors when evaluating relationships between affect and learning, and when making pre/post comparisons. Additionally, this work provides an example of how to implement more appropriate methods for treating data in studies using Likert-type responses and nested data.

2. Advancing undergraduate research through regional community college partnerships at Portland State University

   Rice, A. ; Loikith, P. ; Murry, A. ( December 2023 , Transactions American Geophysical Union)

   Opportunities for undergraduate research in STEM programs at community colleges can be few where lower-division science curriculum emphasizes classroom and laboratory-based learning and research laboratories are limited in number. This is particularly true in the geosciences where specialized programs are extremely rare. Urban serving academic research institutions have a unique role and opportunity to partner with regional community college programs for undergraduate research early-on in student post-secondary educational experiences. Programs built for community college transfer students to urban serving undergraduate programs can serve to integrate students into major programs and help reduce transfer shock. The benefits of exploring research as an undergraduate scholar are numerous and include: building towards mastery of technical skills; developing problem-solving in a real-world environment; reading and digesting scientific literature; analyzing experimental and simulation data; working independently and as part of a team; developing a mentoring relationship with a research advisor; and building a sense of belonging and confidence in a scientific field. However, many undergraduate research internships are targeted towards junior-level STEM majors already engaged in upper-division coursework and considering graduate school which effectively excludes community college students from participating. The Center for Climate and Aerosol Research (CCAR) Research Experience for Undergraduate program at Portland State University serves to help build the future diverse research community. 10-week intern research experiences are paired with an expert faculty mentor are designed for students majoring in the natural/physical sciences but not necessarily with a background in climate or atmospheric science. Additional programmatic activities include: 1-week orientation and training using short courses, faculty research seminars, and hands-on group workshops; academic professional and career development workshops throughout summer; journal club activities; final presentations at end of summer CCAR symposium; opportunities for travel for student presentations at scientific conferences; and social activities. Open to all qualifying undergraduates, since 2014 the program recruits primarily from regional (Northwest) community colleges, rural schools, and Native American serving institutions; recruiting students who would be unlikely to be otherwise exposed to such opportunities at their home institution. Over the past 9 cohorts of REU interns (2014-2019), approximately one third of CCAR REU scholars are community colleges students. Here we present criteria employed for selection of REU scholars and an analysis of selection biases in a comparison of students from community colleges, 4-year colleges, and PhD granting universities. We further investigate differential outcomes in efficacy of the REU program using evaluation data to assess changes over the program including: knowledge, intrinsic motivation, extrinsic motivation, science identity, program satisfaction, and career aspirations. In this presentation, we present these findings along with supportive qualitative analyses and discuss their implications for community college students in undergraduate research programs in geosciences.

3. Impacts Resulting from a Large-Scale First-Year Engineering and Computer Science Program on Students’ Successful Persistence Toward Degree Completion

   Ragusa, Gisele ; Allen, Emily L. ; Menezes, Gustavo B. ( June 2020 , ASEE Annual Conference Proceedings 2020)

   There is a critical need for more students with engineering and computer science majors to enter into, persist in, and graduate from four-year postsecondary institutions. Increasing the diversity of the workforce by inclusive practices in engineering and science is also a profound identified need. According to national statistics, the largest groups of underrepresented minority students in engineering and science attend U.S. public higher education institutions. Most often, a large proportion of these students come to colleges and universities with unique challenges and needs, and are more likely to be first in their family to attend college. In response to these needs, engineering education researchers and practitioners have developed, implemented and assessed interventions to provide support and help students succeed in college, particularly in their first year. These interventions typically target relatively small cohorts of students and can be managed by a small number of faculty and staff. In this paper, we report on “work in progress” research in a large-scale, first-year engineering and computer science intervention program at a public, comprehensive university using multivariate comparative statistical approaches. Large-scale intervention programs are especially relevant to minority serving institutions that prepare growing numbers of students who are first in their family to attend college and who are also under-resourced, financially. These students most often encounter academic difficulties and come to higher education with challenging experiences and backgrounds. Our studied first-year intervention program, first piloted in 2015, is now in its 5th year of implementation. Its intervention components include: (a) first-year block schedules, (b) project-based introductory engineering and computer science courses, (c) an introduction to mechanics course, which provides students with the foundation needed to succeed in a traditional physics sequence, and (d) peer-led supplemental instruction workshops for calculus, physics and chemistry courses. This intervention study responds to three research questions: (1) What role does the first-year intervention’s components play in students’ persistence in engineering and computer science majors across undergraduate program years? (2) What role do particular pedagogical and cocurricular support structures play in students’ successes? And (3) What role do various student socio-demographic and experiential factors play in the effectiveness of first-year interventions? To address these research questions and therefore determine the formative impact of the firstyear engineering and computer science program on which we are conducting research, we have collected diverse student data including grade point averages, concept inventory scores, and data from a multi-dimensional questionnaire that measures students’ use of support practices across their four to five years in their degree program, and diverse background information necessary to determine the impact of such factors on students’ persistence to degree. Background data includes students’ experiences prior to enrolling in college, their socio-demographic characteristics, and their college social capital throughout their higher education experience. For this research, we compared students who were enrolled in the first-year intervention program to those who were not enrolled in the first-year intervention. We have engaged in cross-sectional 2 data collection from students’ freshman through senior years and employed multivariate statistical analytical techniques on the collected student data. Results of these analyses were interesting and diverse. Generally, in terms of backgrounds, our research indicates that students’ parental education is positively related to their success in engineering and computer science across program years. Likewise, longitudinally (across program years), students’ college social capital predicted their academic success and persistence to degree. With regard to the study’s comparative research of the first-year intervention, our results indicate that students who were enrolled in the first-year intervention program as freshmen continued to use more support practices to assist them in academic success across their degree matriculation compared to students who were not in the first-year program. This suggests that the students continued to recognize the value of such supports as a consequence of having supports required as first-year students. In terms of students’ understanding of scientific or engineering-focused concepts, we found significant impact resulting from student support practices that were academically focused. We also found that enrolling in the first-year intervention was a significant predictor of the time that students spent preparing for classes and ultimately their grade point average, especially in STEM subjects across students’ years in college. In summary, we found that the studied first-year intervention program has longitudinal, positive impacts on students’ success as they navigate through their undergraduate experiences toward engineering and computer science degrees.

4. Relationship Between Goal Orientation, Agency, and Motivation in Undergraduate Civil Engineering Students

   O'Hara, R. ; Benson, L. ; Ogle, J. ; Bolding, C.J. ( July 2021 , 2021 ASEE Annual Conference)

   Understanding the underlying psychological constructs that affect undergraduate engineering students’ academic achievement and persistence can inform curricular and programmatic changes in engineering education, with the goal of increasing access and advancement in engineering for a diverse population of students. As part of a larger study examining student experiences in a civil engineering department undergoing curricular and cultural changes, this quantitative study investigated the relationship between goal orientation, agency, and time-oriented motivation, differences in this relationship across academic years, and potential influences from personality types. The larger project seeks to examine the motivation, identity, and sense of belonging for undergraduate civil engineering students; this paper seeks to construct a conceptual model explaining the interactive nature of some of these constructs. A previously tested and established survey that draws from multiple theories of motivation and other affective factors such as agency and identity, and that includes Big 5 personality constructs, was used to collect data from second, third-and fourth-year civil engineering students over a two-year period. Prior studies have focused on the instrument’s latent constructs with sense of belonging. However, no analysis has been conducted to examine how some of the constructs influence each other. Specific latent constructs of goal orientation, agency (students’ beliefs that their career in science or engineering can lead to positive effects on the world), FTP, and personality were selected for secondary data analysis based on theory presented in the literature about relationships between motivation, goal setting, agency, and student perceptions of their future. The sample size of respondents was 843; data cleaning and deletion of missing data (65cases; 7.7%) resulted in a final sample size of 778(92.3% of the original data). This included328 second year, 294 third year and 156 fourth year students. Statistical analyses and modeling included bivariate correlational analysis, MANOVA and MANCOVA. Results indicated significant correlation between goal orientation, agency, and time-oriented motivation. Furthermore, differences in these constructs between academic years and personality type influenced the relationship. FTP differed between sophomores and seniors, with seniors having higher scores, suggesting motivation increases as time in the program increases. Personality significantly influenced these relationships in different ways but had the strongest effect on agency. The findings that certain types of people are not only motivated to go into civil engineering but believe their major will make a difference in the world, have implications for educational practice. Results align with current literature but also shed light onto the effects of personality on time-oriented motivation and agency, expanding theory in engineering education. Further research is needed to determine if the effects of personality hold true for other engineering and science majors.

5. Teaching little kids big sentences: A randomized controlled trial showing that children with DLD respond to complex syntax intervention embedded within the context of preschool/kindergarten science instruction

   https://doi.org/10.1111/1460-6984.12882  

   Owen Van Horne, Amanda J. ; Curran, Maura ; Cook, Susan Wagner ; Cole, Renée ; McGregor, Karla K. ( May 2023 , International Journal of Language & Communication Disorders)

   The language of the science curriculum is complex, even in the early grades. To communicate their scientific observations, children must produce complex syntax, particularly complement clauses (e.g.,I think it will float;We noticed that it vibrates). Complex syntax is often challenging for children with developmental language disorder (DLD), and thus their learning and communication of science may be compromised.

   We asked whether recast therapy delivered in the context of a science curriculum led to gains in complement clause use and scientific content knowledge. To understand the efficacy of recast therapy, we compared changes in science and language knowledge in children who received treatment for complement clauses embedded in a first‐grade science curriculum to two active control conditions (vocabulary + science, phonological awareness + science).

   This 2‐year single‐site three‐arm parallel randomized controlled trial was conducted in Delaware, USA. Children with DLD, not yet in first grade and with low accuracy on complement clauses, were eligible. Thirty‐three 4–7‐year‐old children participated in the summers of 2018 and 2019 (2020 was cancelled due to COVID‐19). We assigned participants to arms using 1:1:1 pseudo‐random allocation (avoiding placing siblings together). The intervention consisted of 39 small‐group sessions of recast therapy, robust vocabulary instruction or phonological awareness intervention during eight science units over 4 weeks, followed by two science units (1 week) taught without language intervention. Pre‐/post‐measures were collected 3 weeks before and after camp by unmasked assessors.

   Primary outcome measures were accuracy on a 20‐item probe of complement clause production and performance on ten 10‐item unit tests (eight science + language, two science only). Complete data were available for 31 children (10 grammar, 21 active control); two others were lost to follow‐up. Both groups made similar gains on science unit tests for science + language content (pre versus post,d= 2.9,p< 0.0001; group,p= 0.24). The grammar group performed significantly better at post‐test than the active control group (d= 2.5,p= 0.049) on complement clause probes and marginally better on science‐only unit tests (d= 2.5,p= 0.051).

   Children with DLD can benefit from language intervention embedded in curricular content and learn both language and science targets taught simultaneously. Tentative findings suggest that treatment for grammar targets may improve academic outcomes.

   We know that recast therapy focused on morphology is effective but very time consuming. Treatment for complex syntax in young children has preliminary efficacy data available. Prior research provides mixed evidence as to children’s ability to learn language targets in conjunction with other information.

   This study provides additional data supporting the efficacy of intensive complex syntax recast therapy for children ages 4–7 with Developmental Language Disorder. It also provides data that children can learn language targets and science curricular content simultaneously.

   As SLPs, we have to talk about something to deliver language therapy; we should consider talking about curricular content. Recast therapy focused on syntactic frames is effective with young children.
