The effect of authentic project-based learning on attitudes and career aspirations in STEM

Can engaging college students in client-centered projects in science, technology, engineering, and mathematics (STEM) coursework increase interest in STEM professions? The current study explored the effectiveness of project-based learning (PjBL) courses on student attitudes, major choice, and career aspirations in STEM. Framed in expectancy-value and social cognitive career choice models, we examined the effect of engaging in at least one authentic, project-based course during the first four semesters of college on student STEM attitudes and career aspirations in a quasi-experimental study with a sample of (N = 492) natural science and engineering students. STEM self-efficacy and subjective task value variables (STEM attainment, intrinsic and utility value of STEM courses, and relative cost associated with engaging in STEM courses) were examined as mediators of the relationship between classroom project-based experiences and STEM career aspirations. Gender and underrepresented minority status were also examined. We found that engaging in at least one project-based course during the first four semesters affected student perceptions of STEM skills, perceptions of the utility value of participating in STEM courses, and STEM career aspirations. Furthermore, we found that the effect of project-based courses on STEM career aspirations was mediated by STEM skills and perceptions of course utility. The effect of PjBL was not moderated by race or gender. We highlight areas of future research and the promise of PjBL for engaging students in STEM professions.     

Playing catch up: A term-level investigation of the racial gap in STEM retention

This paper examines differences in STEM retention between minority and non-minority students enrolled at the University of California, Los Angeles (UCLA) from 1980 through 2006. Using detailed administrative records of undergraduate students, we document that minority students and non-minority students take divergent pathways through the STEM major. Specifically, minority students take fewer lower division STEM courses in their early career, which delays their enrollment in upper division STEM courses and leads to lower graduation probability in STEM within four years and higher dropout rates. We investigate the potential reasons (and/or predictors) for this apparent discrepancy. To do so, we first identify a student’s major-specific Individual Performance Potential (IPP) from lower division course regressions. We find that once we control for the heterogeneity in the IPP’s and a rich set of term level controls, the differences in intermediate outcomes (declared major, STEM course load) between minority and non-minority students largely disappear, but that some of the gap in outcomes persist, with the exception being in graduation from STEM within five years, for which minority students are more likely after controlling for these factors. Our findings suggest that minority STEM majors would benefit from additional support such as early career course advising.     

The Role of Teaching Assistants in Student-Centered Learning: Benefits, Costs, and Negotiations

As more faculty members utilize student-centered methods, we should also expect to see an increase in graduate teaching assistants (TAs) who are asked to co-teach these classes. However, little is written about the challenges TAs face and the adjustments they make when teaching student-centered courses. This study examined a student-centered course taught by the hevruta method, a dyadic approach that emphasizes text-based student discussions. Although students reported significant learning gains, both they and TAs had to negotiate new instructional roles. Based on student and TA feedback, strategies are presented to facilitate effective student learning in a student-centered course co-taught by TAs.     

The role of stereotype threat in ethnically minoritized students’ science motivation: A four-year longitudinal study of achievement and persistence in STEM

Grounded in expectancy-value and stereotype threat theories, this four-year longitudinal study examined associations between changes in stereotype threat and motivation (self-efficacy, task values, and perceived costs) among 425 undergraduates from racial/ethnic groups typically underrepresented in science, technology, engineering, and mathematics (STEM). Growth analyses indicated that students’ stereotype threat and perceived cost of studying science increased during college, whereas science self-efficacy, intrinsic value, and attainment value declined. Parallel growth analyses suggested that higher initial stereotype threat related to a faster decline in attainment value and faster increase in perceived costs throughout college. Higher initial levels and a steeper increase in stereotype threat related to lower STEM GPA. Higher initial levels and a slower decline in motivation variables related to higher STEM GPA and more completed STEM courses. These findings provide empirical evidence for the relations between stereotype threat and motivation among underrepresented minority students during a key developmental period.     

Engaging in science practices in classrooms predicts increases in undergraduates' STEM motivation,identity, and achievement: A short-term longitudinal study

Our short-term longitudinal study explored undergraduate students' experiences with performing authentic science practices in the classroom in relation to their science achievement and course grades. In addition, classroom experiences (felt recognition as a scientist and perceived classroom climate) and changes over a 10-week academic term in STEM (science, technology, engineering, and mathematics) identity and motivation were tested as mediators. The sample comprised 1,079 undergraduate students from introductory biology classrooms (65.4% women, 37.6% Asian, 30.2% White, 25.1% Latinx). Using structural equation modeling (SEM), our hypothesized model was confirmed while controlling for class size and GPA. Performing science practices (e.g., hypothesizing or explaining results) positively predicted students' felt recognition as a scientist; and felt recognition positively predicted perceived classroom climate. In turn, felt recognition and classroom climate predicted increases over time in students' STEM motivation (expectancy-value beliefs), STEM identity, and STEM career aspirations. Finally, these factors predicted students' course grade. Both recognition as a scientist and positive classroom climate were more strongly related to outcomes among underrepresented minority (URM) students. Findings have implications for why large-format courses that emphasize opportunities for students to learn science practices are related to positive STEM outcomes, as well as why they may prove especially helpful for URM students. Practical implications include the importance of recognition as a scientist from professors, teaching assistants, and classmates in addition to curriculum that engages students in the authentic practices of science.     

Mentoring partnerships in science education

The authors use an action research (AR) approach in a collegiate studio physics class to investigate the power of partnerships via conferences as they relate to issues of establishing a student/mentor rapport, empowering students to reduce inequity, and the successes and barriers to hearing students’ voices. The graduate teaching assistant (TA, Author 1) conducted one-on-one conferences with 29 students, elicited student opinions about the progress of the course, and talked with faculty, TAs, and an undergraduate supplemental instructor for other sections of the course. At the end of the semester, the students reported increased knowledge of the TA as a person and as an instructor, and vice versa. Sixty-five percent of students reported no interest in changing circumstances to make it easier to talk about personal concerns with the TA. College students reluctantly voiced their opinions about the course, possibly due to the power structure of the classroom. Other TAs in the department expressed mostly disinterest in the project, while faculty members were interested in student learning but skeptical of student empowerment. A case study of one student is presented, wherein his attendance improved in the course and he received additional help outside class, both possibly as a result of the student/TA conferences. Students in this studio physics section were more likely to interact directly with faculty or TAs during lectures, but less likely to do so during lab sessions, than were students in a non-studio physics section.     

STEM Doctoral Completion of Underrepresented Minority Students: Challenges and Opportunities for Improving Participation in the Doctoral Workforce

This article is a result of the analysis of student-level enrollment records from twenty-one research universities in the United States, and it contributes to a more robust understanding of timely completion of STEM doctorates by underrepresented minority students. Using multivariate logit regression models, findings indicated that Hispanic/Latino and students from other underrepresented groups complete at higher rates than do their Black/African American counterparts. Findings also indicated that prior master’s degrees and institutional participation in doctoral completion programs positively correlate with STEM doctoral completion. We conclude by offering insights and recommendations for graduate schools about how to increase the STEM doctoral attainment rate of students from underrepresented groups.     

“It’s Like I’m Really There”: Using VR Experiences for STEM Career Development

Research suggests that the likelihood of students entering into science, technology, engineering, and mathematics (STEM) careers can be increased by promoting and maintaining students’ interest in STEM during middle school years, a critical developmental stage when students’ interests begin to solidify. One way to attract students to STEM is through technology-enhanced learning environments and experiences, which can spark and cultivate the long-term interest needed to pursue STEM careers. Virtual reality (VR) can potentially increase access to such STEM-related experiences for all students due to its educational and technological affordances. Currently, there has been little exploration of the intersection between VR and career development for K-12 students. This study, therefore, aims to address this gap by exploring the use of VR 360 videos for STEM career exploration. Data were collected using focus group interviews with 39 primarily Latinx middle school students who participated in the summer enrichment program. These interviews were conducted immediately after a VR 360 video activity that featured female characters and/or characters from racial minorities in order to best support students who are underrepresented in STEM fields. The findings support the potential of VR as a tool for career development as long as content, possible physical side effects, and scaffolding are considered. The implications for research and practice are discussed.

     

The effect of instructor race and gender on student persistence in STEM fields

The objective of this study is to determine if minority and female students are more likely to persist in a science, technology, engineering, and math (STEM) major when they enroll in classes taught by instructors of their own race or gender. Using data from public 4-year universities in the state of Ohio, I analyze first semester STEM courses to see if the race or gender of the instructor effects persistence of initial STEM majors in a STEM field after the first semester and first year. Results indicate that black students are more likely to persist in a STEM major if they have a STEM course taught by a black instructor. Similar to previous findings, female students are less likely to persist when more of their STEM courses are taught by female instructors.     

Hierarchical Mentoring: A Transformative Strategy for Improving Diversity and Retention in Undergraduate STEM Disciplines

In the United States, less than half of the students who enter into science, technology, engineering, and mathematics (STEM) undergraduate curricula as freshmen will actually graduate with a STEM degree. There is even greater disparity in the national STEM graduation rates of students from underrepresented groups with approximately three-fourths of minority students leaving STEM disciplines at the undergraduate level. A host of programs have been designed and implemented to model best practices in retaining students in STEM disciplines. The Howard Hughes Medical Institute (HHMI) Professors Program at Louisiana State University, under leadership of HHMI Professor Isiah M. Warner, represents one of these programs and reports on a mentoring model that addresses the key factors that impact STEM student attrition at the undergraduate level. By integrating mentoring and strategic academic interventions into a structured research program, an innovative model has been developed to guide STEM undergraduate majors in adopting the metacognitive strategies that allow them to excel in their programs of study, as they learn to appreciate and understand science more completely. Comparisons of the persistence of participants and nonparticipants in STEM curricular, at the host university and with other national universities and colleges, show the impact of the model’s salient features on improving STEM retention through graduation for all students, particularly those from underrepresented groups.     

Teaching Assistant Professional Development in Biology: Designed for and Driven by Multidimensional Data

Graduate teaching assistants (TAs) are increasingly responsible for instruction in undergraduate science, technology, engineering, and mathematics (STEM) courses. Various professional development (PD) programs have been developed and implemented to prepare TAs for this role, but data about effectiveness are lacking and are derived almost exclusively from self-reported surveys. In this study, we describe the design of a reformed PD (RPD) model and apply Kirkpatrick''s Evaluation Framework to evaluate multiple outcomes of TA PD before, during, and after implementing RPD. This framework allows evaluation that includes both direct measures and self-reported data. In RPD, TAs created and aligned learning objectives and assessments and incorporated more learner-centered instructional practices in their teaching. However, these data are inconsistent with TAs’ self-reported perceptions about RPD and suggest that single measures are insufficient to evaluate TA PD programs.     

Bayer Facts of Science Education XV: A View from the Gatekeepers—STEM Department Chairs at America’s Top 200 Research Universities on Female and Underrepresented Minority Undergraduate STEM Students

Diversity and the underrepresentation of women, African-Americans, Hispanics and American Indians in the nation’s science, technology, engineering and mathematics (STEM) fields are the subjects of the XV: A View from the Gatekeepers—STEM Department Chairs at America’s Top 200 Research Universities on Female and Underrepresented Minority Undergraduate STEM Students. Annual public opinion research project commissioned by Bayer Corporation, the Bayer Facts surveys examine science education and science literacy issues. The 15th in the series and the fifth to explore diversity and underrepresentation, this research is a direct outgrowth of last year’s results which found 40 percent of the country’s female and underrepresented minority (URM) chemists and chemical engineers working today were discouraged from pursuing their STEM career at some point in their lives. US colleges were cited as places where this discouragement most often happened and college professors as the individuals most likely responsible. Does such discouragement still occur in American colleges today? To answer this and other questions about the undergraduate environment in which today’s students make their career decisions, the survey polls 413 STEM department chairs at the nation’s 200 top research universities and those that produce the highest proportion of female and URM STEM graduates. The survey also asks the chairs about their institutions track record recruiting and retaining female and URM STEM undergraduates, preparedness of these students to study STEM, the impact of traditional introductory STEM courses on female and URM students and barriers these students face pursuing their STEM degrees.     

Impact of Adaptive Materials on Teachers and their Students with Visual Impairments in Secondary Science and Mathematics Classes

Science, technology, engineering, and mathematics (STEM) fields, important in today’s world, are underrepresented by students with disabilities. Students with visual impairments, although cognitively similar to sighted peers, face challenges as STEM subjects are often taught using visuals. They need alternative forms of access such as enlarged or audio‐converted text, tactile graphics, and involvement in hands‐on science. This project focused on increasing teacher awareness of and providing funds for the purchase of supplemental adaptive resources, supplies, and equipment. We examined attitude and instructional changes across the year of the programme in 15 science and mathematics teachers educating students with visual impairments. Positive changes were noted from pretest to posttest in student and teacher perspectives, and in teacher attitudes towards students with disabilities in STEM classes. Teachers also provided insights into their challenges and successes through a reflective narrative. Several adolescent students resisted accommodations to avoid appearing conspicuous to peers. Teachers implemented three strategies to address this: providing the adaptations to all students in the class; convincing the student of the need for adaptation; and involving the class in understanding and accepting the student’s impairment. A variety of teacher‐created adaptations for various science and mathematics labs are reported. Another finding was many adaptations provided for the student with visual impairment benefitted the entire class. This study supports the claim that given knowledgeable, supportive teachers, and with appropriate accommodations such as tactile or auditory materials, students with visual impairments can be as successful and engaged as other students in science and mathematics.     

Pressurizing the STEM Pipeline: an Expectancy-Value Theory Analysis of Youths’ STEM Attitudes

Over the past decade, there has been a strong national push to increase minority students’ positive attitudes towards STEM-related careers. However, despite this focus, minority students have remained underrepresented in these fields. Some researchers have directed their attention towards improving the STEM pipeline which carries students through our educational system and into STEM careers. Previous research has shown that expectancy-value theory (EVT) is useful for examining the short-term as well as long-term academic motivations and intentions of elementary age minority students. These findings provide insights into ways we may be able to potentially “patch” particular STEM pipeline leaks. In the current study, we advance this research by using EVT as a framework to examine the STEM attitudes of young students directly. We hypothesize that students’ academic-related expectancies for success and subjective task values will be associated with an increase in STEM attitudes. Data for this study was gathered over the course of a large-scale computing intervention which sought to increase students’ STEM interest. This computing intervention took place in an urban elementary school district located within the southeastern USA. Results from this study indicate that both intrinsic values and utility values predict students’ STEM attitudes but they influence attitudes related to the various dimensions of STEM differently. These findings demonstrate that EVT provides a useful framework, which can be integrated into future computing interventions, to help encourage positive STEM attitudes in young children, thus increasing the internal pressure (or flow) within the STEM pipeline.     

Face‐to‐face versus online tuition: Preference,performance and pass rates in white and ethnic minority students

Attainment in higher education tends to be poorer in ethnic minority students than in white students. This study examined whether this attainment gap was affected by the introduction of online tuition. Data were obtained from students who had taken courses in either arts or management with the UK Open University and had opted for either face‐to‐face or online tuition. The arts courses had a higher proportion of white students and lower proportions of Asian and black students than the management courses. Nevertheless, white and ethnic minority students gave similar reasons for choosing face‐to‐face tuition or online tuition. In the management courses but not in the arts courses, the pass rate was lower in students who had received online tuition than in students who had received face‐to‐face tuition. Regardless of the discipline or mode of tuition, black students tended to obtain lower marks and lower pass rate than white students, but Asian students did not. It is concluded that online tuition is an appropriate form of student support in both campus‐based and distance education but that the attainment gap in ethnic minority students probably does not arise from the nature and quality of their interactions with teachers and other students.     

Who mentors undergraduate student researchers? An analysis of faculty involvement at a four-year university

ABSTRACT

In this study, we investigated a profile of faculty who mentor undergraduate researchers at a four-year Hispanic-serving, public research university. Six variables were investigated: ethnicity, gender, age, tenure status, teaching evaluations, and research productivity. Data were compiled from institutional databases. Findings showed a greater percentage of tenured faculty mentoring undergraduate researchers while the percent of minority UR faculty mentors was consistent with institutional percentages. Additionally, findings included a higher percentage of Science, Technology, Engineering, and Math (STEM) Undergraduate Research (UR) underrepresented minority faculty mentors compared to STEM Institution (INST) underrepresented minority faculty. For research productivity, UR faculty mentor funding comprised 28.0% of all external grant awards and 36.0% of all external funding during the sampling period. The majority funding for INST and UR faculty were found to be in the STEM disciplines. These findings provide evidence of potential predictors to describe UR faculty mentor profiles and can be considered important information for determining future educational policies and practices.     

Double standards and first principles: framing teaching assistant support for pupils with special educational needs

Teaching assistants (TAs) are part of a growing international trend toward paraprofessionals working in public services. There has been controversy over TAs’ deployment and appropriate role when supporting the learning of pupils with special educational needs (SEN) in mainstream schools. Such debates have been transformed by findings from a large study of school support staff in the UK (the DISS project). The findings from this study show that TA support has a negative impact on pupils’ academic progress, especially pupils with SEN. The findings render the current system of support for SEN highly questionable: TAs have inadvertently become the primary educators of pupils with SEN. This paper sets out the likely explanations for the negative effects in terms of three ‘frames’ – deployment, practice and preparedness – and then uses these frames to identify specific implications for pupils with SEN. We offer suggestions on how to make the most productive use of TA support.     

Increasing Persistence in Undergraduate Science Majors: A Model for Institutional Support of Underrepresented Students

The 6-yr degree-completion rate of undergraduate science, technology, engineering, and mathematics (STEM) majors at U.S. colleges and universities is less than 40%. Persistence among women and underrepresented minorities (URMs), including African-American, Latino/a, Native American, and Pacific Islander students, is even more troubling, as these students leave STEM majors at significantly higher rates than their non-URM peers. This study utilizes a matched comparison group design to examine the academic achievement and persistence of students enrolled in the Program for Excellence in Education and Research in the Sciences (PEERS), an academic support program at the University of California, Los Angeles, for first- and second-year science majors from underrepresented backgrounds. Results indicate that PEERS students, on average, earned higher grades in most “gatekeeper” chemistry and math courses, had a higher cumulative grade point average, completed more science courses, and persisted in a science major at significantly higher rates than the comparison group. With its holistic approach focused on academics, counseling, creating a supportive community, and exposure to research, the PEERS program serves as an excellent model for universities interested in and committed to improving persistence of underrepresented science majors and closing the achievement gap.     

Examining the impact of four teaching development programmes for engineering teaching assistants*

As current graduate instructors of labs and class discussions, teaching assistants (TAs) play a critical role in Science, Technology, Engineering, and Math (STEM) undergraduate education, especially as some graduate students may choose a faculty career in the future. Because of the importance of TAs and their development as scholars and instructors, we sought to determine the most effective methods of preparing engineering TAs at two research universities. We compare the impact of a teaching orientation with one of four teaching development programmes (Pedagogy Course, Advanced Practice Teaching, Workshop Attendance with Written Reflection, or Mid-Semester Student Feedback with Written Reflection) on engineering TAs’ teaching efficacy and definitions of active learning. Results indicated that the Pedagogy Course consistently increased TAs’ teaching efficacy and attitudes toward teaching compared with the other programmes. We also found that stand-alone Mid-Semester Student Feedback with Written Reflection enhanced TAs’ efficacy for reflection and beliefs about teaching. We discuss implications for providing teaching development for graduate students and directions for future research.     

Statistics for Educational Workers

ABSTRACT

Present federal education policies promote learning in science, technology, engineering, and mathematics (STEM) and the participation of minority students in these fields. Using longitudinal data on students in Florida and North Carolina, value-added estimates in mathematics and science are generated to categorize schools into performance levels and identify differences in school STEM measures by performance levels. Several STEM-relevant variables show a significant association with effectiveness in mathematics and science, including STEM teacher turnover, calculus and early algebra participation, and mathematics and science instructional indices created from survey items in the data. Surprisingly, a negative association between students’ STEM course participation and success in STEM is consistently documented across both states, in addition to low participation of underrepresented minority students in successful schools in STEM.
