Helping Struggling Students in Introductory Biology: A Peer-Tutoring Approach That Improves Performance,Perception, and Retention

The high attrition rate among science, technology, engineering, and mathematics (STEM) majors has long been an area of concern for institutions and educational researchers. The transition from introductory to advanced courses has been identified as a particularly “leaky” point along the STEM pipeline, and students who struggle early in an introductory STEM course are predominantly at risk. Peer-tutoring programs offered to all students in a course have been widely found to help STEM students during this critical transition, but hiring a sufficient number of tutors may not be an option for some institutions. As an alternative, this study examines the viability of an optional peer-tutoring program offered to students who are struggling in a large-enrollment, introductory biology course. Struggling students who regularly attended peer tutoring increased exam performance, expert-like perceptions of biology, and course persistence relative to their struggling peers who were not attending the peer-tutoring sessions. The results of this study provide information to instructors who want to design targeted academic assistance for students who are struggling in introductory courses.     

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.     

Correlation between MCAT Biology Content Specifications and Topic Scope and Sequence of General Education College Biology Textbooks

Most American colleges and universities offer gateway biology courses to meet the needs of three undergraduate audiences: biology and related science majors, many of whom will become biomedical researchers; premedical students meeting medical school requirements and preparing for the Medical College Admissions Test (MCAT); and students completing general education (GE) graduation requirements. Biology textbooks for these three audiences present a topic scope and sequence that correlates with the topic scope and importance ratings of the biology content specifications for the MCAT regardless of the intended audience. Texts for “nonmajors,” GE courses appear derived directly from their publisher''s majors text. Topic scope and sequence of GE texts reflect those of “their” majors text and, indirectly, the MCAT. MCAT term density of GE texts equals or exceeds that of their corresponding majors text. Most American universities require a GE curriculum to promote a core level of academic understanding among their graduates. This includes civic scientific literacy, recognized as an essential competence for the development of public policies in an increasingly scientific and technological world. Deriving GE biology and related science texts from majors texts designed to meet very different learning objectives may defeat the scientific literacy goals of most schools’ GE curricula.     

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.     

From Gatekeeping to Engagement: A Multicontextual, Mixed Method Study of Student Academic Engagement in Introductory STEM Courses

The lack of academic engagement in introductory science courses is considered by some to be a primary reason why students switch out of science majors. This study employed a sequential, explanatory mixed methods approach to provide a richer understanding of the relationship between student engagement and introductory science instruction. Quantitative survey data were drawn from 2,873 students within 73 introductory science, technology, engineering, and mathematics (STEM) courses across 15 colleges and universities, and qualitative data were collected from 41 student focus groups at eight of these institutions. The findings indicate that students tended to be more engaged in courses where the instructor consistently signaled an openness to student questions and recognizes her/his role in helping students succeed. Likewise, students who reported feeling comfortable asking questions in class, seeking out tutoring, attending supplemental instruction sessions, and collaborating with other students in the course were also more likely to be engaged. Instructional implications for improving students’ levels of academic engagement are discussed.     

Biology Intensive Orientation for Students (BIOS): a biology "boot camp"

The Biology Intensive Orientation for Students (BIOS) Program was designed to assess the impact of a 5-d intensive prefreshman program on success and retention of biological science majors at Louisiana State University. The 2005 pilot program combined content lectures and examinations for BIOL 1201, Introductory Biology for Science Majors, as well as learning styles assessments and informational sessions to provide the students with a preview of the requirements of biology and the pace of college. Students were tracked after their BIOS participation, and their progress was compared with a control group composed of students on the BIOS waiting list and a group of BIOL 1201 students who were identified as the academic matches to the BIOS participants (high school GPA, ACT score, and gender). The BIOS participants performed significantly better on the first and second exams, they had a higher course average, and they had a higher final grade than the control group. These students also had higher success rates (grade of “A,” “B,” or “C”) during both the fall and spring semesters and remained on track through the first semester of their sophomore year to graduate in 4 yr at a significantly higher rate than the control group.     

Comprehensive Cocurricular Support Promotes Persistence of Community College STEM Students

ABSTRACT

Despite good career prospects in science, technology, engineering, and mathematics (STEM) fields, persistence of students in STEM fields of study at the community college and transfer to universities to pursue STEM majors is often quite low. Theories of persistence emphasize the importance of engagement, integration, validation, and financial assistance. The DCCCD STEM Institute is a comprehensive cocurricular program for community college STEM students. It illustrates the application of persistence theories in a multicollege urban district with a diverse student body. The STEM Institute uses a student/faculty cohort model with mentoring, professional skills programming, and scholarship support to transform student perceptions of themselves, integrate them into a STEM educational community, and validate their membership within that community. Institute membership also reduces isolation and financial concerns as potential barriers to persistence. STEM faculty also participate in professional skill development through a cross-college and cross-disciplinary cohort. Data on students who participated in the DCCCD STEM Institute from 2010 through 2014 show that 92% remain in a STEM educational or career pathway. Important practice implications for community college professionals include (1) forming student and faculty cohorts, (2) facilitating the development of mentoring relationships, (3) providing adequate centralized staffing, and (4) integrating resources and opportunities into a unified cocurricular program.     

Tracking Financial Aid and Persistence of Women,Minority, and Needy Students in Science,Engineering, and Mathematics

This longitudinal research study focused on persistence and financial aid of women, underrepresented minorities, and needy students majoring in science, engineering, and mathematics (SEM) in a large, public university in a metropolitan area. Beginning in fall 1989, four consecutive freshmen cohorts (n's = 1967, 1679, 1614, and 1924, respectively) were tracked through 1996–97. SEM majors persisted and graduated at higher rates, but took longer to graduate than non-SEM majors. Women, underrepresented minorities, and needy students received more gift aid than other student populations. However, only women had lower departure rates and graduated at higher rates than other SEM student populations. Compared to non-SEM majors, gift aid for SEM majors was more likely to be awarded on the basis of merit rather than need. Average loan indebtedness increased rapidly from 1989–90 through 1996–97 for both SEM and non-SEM majors. Implications of the findings for improved institutional and federal policy are indicated, and further research on the study topics recommended.     

Profiles of Motivated Self-Regulation in College Computer Science Courses: Differences in Major versus Required Non-Major Courses

The goal of the present study was to utilize a profiling approach to understand differences in motivation and strategic self-regulation among post-secondary STEM students in major versus required non-major computer science courses. Participants were 233 students from required introductory computer science courses (194 men; 35 women; 4 unknown) at a large Midwestern state university. Cluster analysis identified five profiles: (1) a strategic profile of a highly motivated by-any-means good strategy user; (2) a knowledge-building profile of an intrinsically motivated autonomous, mastery-oriented student; (3) a surface learning profile of a utility motivated minimally engaged student; (4) an apathetic profile of an amotivational disengaged student; and (5) a learned helpless profile of a motivated but unable to effectively self-regulate student. Among CS majors and students in courses in their major field, the strategic and knowledge-building profiles were the most prevalent. Among non-CS majors and students in required non-major courses, the learned helpless, surface learning, and apathetic profiles were the most prevalent. Students in the strategic and knowledge-building profiles had significantly higher retention of computational thinking knowledge than students in other profiles. Students in the apathetic and surface learning profiles saw little instrumentality of the course for their future academic and career objectives. Findings show that students in STEM fields taking required computer science courses exhibit the same constellation of motivated strategic self-regulation profiles found in other post-secondary and K-12 settings.     

A Research Preparatory Program for First-Year College Students: Student Selection and Preparation Lead to Persistence in Research

Undergraduate research experiences may increase persistence in STEM majors. We describe a research program that targets first-year students selected for their curiosity and attitudes towards science. We explain the implementation of the program over 3 years and present evaluation data using a group of matched controls. Participants and controls pursued STEM degrees at equivalent rates, but participants were significantly more involved in research. Initial laboratory interest and mentor pairing may have played a role in this finding. Female participants, particularly those with male laboratory mentors, engaged in more research than men.     

Promoting cognitive and soft skills acquisition in a disadvantaged public school system: Evidence from the Nurture thru Nature randomized experiment

It is widely acknowledged that our public schools have failed to produce sufficient levels of high quality STEM education. The mathematics and science performance of minority and disadvantaged students has been especially troubling with blacks and Hispanics substantially underrepresented in the STEM labor market. In this paper we examine the impacts of a STEM enhancement program called Nurture thru Nature (NtN) on the cognitive (academic grades) and soft skills development of 139 elementary school students who attended the program over an eight year period (2010–2017). Utilizing a randomized experimental design or RCT with a control group of 491 elementary school students, we find that NtN slows the deterioration in students’ math and science grades relative to controls and improves soft skills such as conscientiousness, higher order thinking, empathy, and pro-social behavior.     

Closing the Gaps and Filling the STEM Pipeline: A Multidisciplinary Approach

There is a growing demand for degreed science, technology, engineering and mathematics (STEM) professionals, but the production of degreed STEM students is not keeping pace. Problems exist at every juncture along the pipeline. Too few students choose to major in STEM disciplines. Many of those who do major in STEM drop out or change majors. Females and minorities remain underrepresented in STEM. The success rate of college students who are from low-income background or first-generation students is much lower than that of students who do not face such challenges. Some of those who successfully complete their degree need help in making the transition to the workforce after graduation. A program at Lamar University takes a multidisciplinary approach to addressing these problems. It is designed to recruit, retain and transition undergraduates to careers in STEM, focusing its efforts on five science disciplines and on these “at-risk” students. The program was supported by a 5-year grant from the National Science Foundation and is supported through August 31, 2016 by Lamar University and a grant from ExxonMobil. A formal assessment plan documents the program’s success. The program received an award from the Texas Higher Education Board for its contributions towards Closing the Gaps in Higher Education in Texas. This paper describes the program’s theoretical framework, research questions, methods, evaluation plan, and instruments. It presents an analysis of the results achieved using these methods and implications for improvements to the program resulting from lessons learned.     

Religion as a Support Factor for Women of Color Pursuing Science Degrees: Implications for Science Teacher Educators

This study explores the influence of religion as a support factor for a group of Latina and African-American women majoring in science. The current project is a part of a larger study that investigated persistence factors of underrepresented woman who were enrolled as science majors at United States colleges and universities. This paper focuses on one theme that emerged among six participants who disclosed how religion was a significant influence on their persistence in science fields. The strength and support offered by religious values is certainly not specific to science content; however, the support received from their beliefs highlights a potential area for further exploration. Given the importance of increasing participation by students from diverse backgrounds into science fields, it is critical to recognize how some of these differences may be the key factors influencing the way these students look at the world. This study offers evidence that science educators need to consider what role religious beliefs have for students who may be considering science or science education as a future career, particularly for those students from underrepresented groups.     

Breaking it Down: Engineering Student STEM Confidence at the Intersection of Race/Ethnicity and Gender

It is generally accepted that engineering requires a strong aptitude for mathematics and science; therefore, students’ judgments regarding their competence in these areas as well as engineering likely influence their confidence in engineering. Little is known about how self-confidence in science, mathematics, and engineering courses (STEM confidence) varies at the intersection of race/ethnicity and gender. To fill this gap, this study examined the STEM confidence of multiple groups in undergraduate engineering programs. Results indicated that although some underrepresented groups may have lower STEM confidence overall, this finding no longer applies to all groups after controlling for personal, environmental, and behavioral factors. Specifically, African-American and Hispanic men report higher average STEM confidence than White men after controlling for these associated measures. In addition, White women continue to report lower average STEM confidence than White men after controlling for these measures, while other groups do not differ from White men. Further, many elements of student perception, including student views of professors, comparisons to peers, perceptions of the field as rewarding, and desirability of chosen major are positively associated with student STEM confidence. The changing patterns of significance for race/ethnicity and gender groups between the two models indicate that personal, environmental, and behavioral factors have different relationships with STEM confidence levels for different groups. This study contributes an understanding that gender differences in STEM confidence are not indifferent to racial and ethnic context. Social-cognitive theory provides a valuable framework for studying student academic confidence and would improve future self-confidence research.     

Bye bye Ms. American Sci: Women and the leaky STEM pipeline

More than two-thirds of STEM jobs are held by men. In this paper, I provide a detailed analysis of the STEM pipeline from high school to mid-career in the United States, decomposing the gender gap in STEM into six stages. Women are lost from STEM before college, during college, and after college. Men are more likely to be STEM-ready before college, scoring higher on science tests and having taken more advanced math and science courses. This accounts for 35% of the overall gender gap in STEM careers. During college, men are far more likely than women to start in a STEM major, accounting for 26% of the gap. After college, male STEM graduates are more likely to enter STEM jobs, accounting for 41%. Men’s higher persistence in STEM majors is a smaller factor, while women attend college at higher rates than men, which works to reduce the final gender gap in STEM. The results show that there is no single stage to focus on in understanding the gender gap in STEM.     

Are changes of major major changes? The roles of grades,gender, and preferences in college major switching

The choice of college major is a key stage in the career search, and over a third of college students switch majors at least once. We provide the first comprehensive analysis of major switching, looking at the patterns of switching in both academic and non-academic dimensions. Low grades signal academic mismatch and predict switching majors - and the lower the grades, the larger the switch in terms of course content. Surprisingly, these switches do not improve students’ grades. When students switch majors, they switch to majors that “look like them”: females to female-heavy majors, and so on. Lower-ability women flee competitive majors at high rates, while men and higher-ability women are undeterred. Women are far more likely to leave STEM fields for majors that are less competitive – but still somewhat science-intensive – suggesting that leaving STEM may be more about fleeing the “culture” of STEM majors than fleeing science and math.     

Beliefs and Attitudes about Science and Mathematics in Pre-Service Elementary Teachers,STEM, and Non-STEM Majors in Undergraduate Physics Courses

Elementary teachers often hold inaccurate beliefs about the Nature of Science (NoS) and have negative attitudes toward science and mathematics. Using a pre-post design, the current study examined beliefs about the NoS, attitudes toward science and mathematics, and beliefs about the teaching of mathematics and science in a large sample study (N = 343) of pre-service teachers receiving a curriculum-wide intervention to improve these factors in comparison with Science, Technology, Engineering, and Mathematics (STEM) and non-STEM majors in other physics courses (N = 6697) who did not receive the intervention, over a 10-year period. Pre-service teachers evidenced initially more negative attitudes about mathematics and science than STEM majors and slightly more positive attitudes than non-STEM majors. Their attitudes toward mathematics and science and beliefs about the NoS were more similar to non-STEM than STEM majors. Pre-service teachers initially evidenced more positive beliefs about the teaching of mathematics and science, and their beliefs even increased slightly over the course of the semester, while these beliefs in other groups remained the same. Beliefs about the NoS and the teaching of mathematics and science were significantly negatively correlated for STEM and non-STEM majors, but were not significantly correlated for pre-service teachers. Beliefs about the NoS and attitudes toward mathematics and science were significantly positively correlated for both pre-service teachers and STEM students pursing the most mathematically demanding STEM majors. Attitudes toward science and mathematics were significantly positively correlated with accurate beliefs about the teaching of mathematics and science for all student groups.     

Building undergraduate STEM majors’ capacity for delivering inquiry-based mathematics and science lessons: An exploratory evaluation study

Recruiting and preparing STEM majors for teaching has become one of the major efforts at improving mathematics and science teacher quality at secondary level. One question is whether STEM majors who have not had the chance to experience active learning in mathematics and science classes as secondary students themselves know what inquiry pedagogy is. Secondly, it is unclear whether those who experienced inquiry in their college introductory discipline courses will be able to utilize the pedagogy in teaching secondary content. We address these questions through studying an undergraduate research methods course designed to improve STEM majors’ capacity for delivering inquiry-based mathematics and science lesson. Analysis of data from pre-and-post course surveys and students’ written research reports including students’ reflection on their inquiry projects suggests that offering future STEM teachers opportunities to conduct inquiry and reflect explicitly on how inquiry can be used to teach secondary content is important and beneficial.     

The Gateway Science Workshop Program: Enhancing Student Performance and Retention in the Sciences Through Peer-Facilitated Discussion

Minority student attrition and underachievement is a long-standing and widespread concern in higher education. It is especially acute in introductory science courses which are prerequisites for students planning to pursue science-related careers. Poor performance in these courses often results in attrition of minorities from the science fields. This is a particular concern at selective universities where minority students enter with excellent academic credentials but receive lower average grades and have lower retention rates than majority students with similar credentials. This paper reports the first year results of a large scale peer-facilitated workshop program designed to increase performance and retention in Biology, Chemistry, and Physics at a selective research university. After adjusting for grade point average or SAT-Math score, workshop participants earned higher final grades than nonparticipants in Biology and Chemistry, but not in Physics. Similar effects on retention were found. While, positive effects of the program were observed in both majority and minority students, effect sizes were generally largest for minority students. Because of practical constraints in Physics, implementation of the program was not optimal, possibly accounting for the differential success of the program across disciplines.
