Estimating the effect of music and arts coursework on college admissions outcomes

The purpose of this study was to examine postsecondary admissions outcomes for music and arts students as compared to their non-arts peers using nationally representative data (N = 14,900) from the Education Longitudinal Study of 2002. Controlling for certain observable differences between students who do and do not elect arts courses, music students were more likely to apply to college and to attend college than their non-arts peers. Arts students were similar to non-arts students in terms of college selectivity and pursued science, technology, mathematics, and engineering majors at similar rates to non-arts students. This analysis suggests taking arts coursework in high school does not hinder successful college admissions outcomes as may be feared by well-intentioned guidance counselors or parents. Implications for college admission and local policies are considered.     

A first attempt to bring computational biology into advanced high school biology classrooms

Computer science has become ubiquitous in many areas of biological research, yet most high school and even college students are unaware of this. As a result, many college biology majors graduate without adequate computational skills for contemporary fields of biology. The absence of a computational element in secondary school biology classrooms is of growing concern to the computational biology community and biology teachers who would like to acquaint their students with updated approaches in the discipline. We present a first attempt to correct this absence by introducing a computational biology element to teach genetic evolution into advanced biology classes in two local high schools. Our primary goal was to show students how computation is used in biology and why a basic understanding of computation is necessary for research in many fields of biology. This curriculum is intended to be taught by a computational biologist who has worked with a high school advanced biology teacher to adapt the unit for his/her classroom, but a motivated high school teacher comfortable with mathematics and computing may be able to teach this alone. In this paper, we present our curriculum, which takes into consideration the constraints of the required curriculum, and discuss our experiences teaching it. We describe the successes and challenges we encountered while bringing this unit to high school students, discuss how we addressed these challenges, and make suggestions for future versions of this curriculum.We believe that our curriculum can be a valuable seed for further development of computational activities aimed at high school biology students. Further, our experiences may be of value to others teaching computational biology at this level.

Elementary education majors experience hands-on learning in introductory biology

Faculty members from the University of South Dakota attended the Curriculum Reform Institute offered by the University of Wisconsin at Oshkosh, WI, during the summer of 2002 to design a course sequence for elementary education majors that better meets their needs for both content and pedagogy based on the science education standards. The special section of introductory biology that resulted from this workshop is designed to use laboratories and activities that either help students learn major concepts in the life sciences or model how to teach these concepts to their future K-8 students. This study describes how the active, hands-on learning opportunity for preservice teachers with its emphasis on both content and performance-based assessment was implemented in an introductory biology course for elementary education majors during the spring of 2004. During the initial offering of this course, student perceptions about what helped them to learn in the special section was compared with their nonscience major peers in the large lecture-intensive class that they would have taken. Each group of students completed early and late web-based surveys to assess their perceptions about learning during the courses. After the completion of the course, students in the special section appreciated how the relevance of science and conducting their own scientific experimentation helped them learn, enjoyed working and studying in small groups, valued diverse class time with very little lecture, were more confident in their abilities in science, and were more interested in discussing science with others. This course format is recommended for science classes for preservice teachers.     

To Believe or not to Believe? A College Student Explores Knowledge and Attitudes about Evolution at her School

After interviewing 17 students and four teachers at Drew University, a college of 1,400 undergraduates which I attend, I found that whereas most express a belief in evolution, many display a hesitancy to embrace the theory entirely. Instead, most students choose to believe only in evolution within lineages and not on a larger scale, specifically in the creation of new species. Teachers at the school explain that their experiences at Drew are similar to those they have experienced at other colleges they have taught at and discuss their methods for introducing the subject in the classroom and the significance of learning evolution. Furthermore, whereas it is easy for students to avoid taking biology classes that would expose them to the theory, I discuss what students look for when taking biology courses and preconceptions teachers must help students overcome when exposing them to evolution.     

University Evolution Education: The Effect of Evolution Instruction on Biology Majors�� Content Knowledge, Attitude Toward Evolution, and Theistic Position

Issues regarding understanding of evolution and resistance to evolution education in the United States are of key importance to biology educators at all levels. While research has measured student views toward evolution at single points in time, few studies have been published investigating whether views of college seniors are any different than first-year students in the same degree program. Additionally, students choosing to major in biological sciences have largely been overlooked, as if their acceptance of evolution is assumed. This study investigated the understanding of evolution and attitude toward evolution held by students majoring in biological science during their first and fourth years in a public research university. Participants included students in a first-year introductory biology course intended for biological science majors and graduating seniors earning degrees in either biology or genetics. The portion of the survey reported here consisted of quantitative measures of students’ understanding of core concepts of evolution and their attitude toward evolution. The results indicate that students’ understanding of particular evolutionary concepts is significantly higher among seniors, but their attitude toward evolution is only slightly improved compared to their first-year student peers. When comparing first-year students and seniors, students’ theistic position was not significantly different.     

Development and evaluation of a genetics literacy assessment instrument for undergraduates

There is continued emphasis on increasing and improving genetics education for grades K-12, for medical professionals, and for the general public. Another critical audience is undergraduate students in introductory biology and genetics courses. To improve the learning of genetics, there is a need to first assess students' understanding of genetics concepts and their level of genetics literacy (i.e., genetics knowledge as it relates to, and affects, their lives). We have developed and evaluated a new instrument to assess the genetics literacy of undergraduate students taking introductory biology or genetics courses. The Genetics Literacy Assessment Instrument is a 31-item multiple-choice test that addresses 17 concepts identified as central to genetics literacy. The items were selected and modified on the basis of reviews by 25 genetics professionals and educators. The instrument underwent additional analysis in student focus groups and pilot testing. It has been evaluated using approximately 400 students in eight introductory nonmajor biology and genetics courses. The content validity, discriminant validity, internal reliability, and stability of the instrument have been considered. This project directly enhances genetics education research by providing a valid and reliable instrument for assessing the genetics literacy of undergraduate students.     

Bridging Multiple Worlds: How African American and Latino Youth in Academic Outreach Programs Navigate Math Pathways to College

Universities have launched outreach programs to enhance their ethnic diversity, yet little developmental research examines students' pathways to college. This study compares capital models (highlighting family background) with challenge models (highlighting students' challenges and resources) in predicting pathways to college. The Bridging Multiple Worlds Model frames this longitudinal study of 120 African American and Latino youth in outreach programs. We examined students' family backgrounds; challenges and resources across family, school, peer, and community worlds; and high school math pathways as predictors of college eligibility and enrollment. African American students more typically had U. S. born, college-educated parents, and Latino students, immigrant parents with high school education or less. Second, students saw parents as greater resources than teachers, siblings, and themselves; peers and teachers were their greatest challenges. Youth distinguished resources and challenges more by their source than form. Third, high school math and English grades rose and fell together, with early math grades predicting college eligibility. Five math pathways emerged: steady, slowly declining, rapidly declining, increasing, and "back on track" toward college, but pathways did not always predict college choices. Fourth, although family background predicted few outcomes, parents' and teachers' help and siblings' challenges predicted grades, eligibility, and admission to prestigious colleges. Findings highlight both capital and challenge models for science, policy, and programs involving diversity and equity.     

Selection and Evolution with a Deck of Cards

Imparting a basic understanding of evolutionary principles to students in an active, engaging fashion can be troublesome because the logistics involved in designing experiments where students pose their own questions and use the data to test alternative hypotheses often outstrip time and financial constraints. In recent years, educators have begun publishing exercises that teach evolution using innovative, in-class experiments. This article adds to this growing forum by describing a classroom exercise that introduces the concept of evolution by natural selection in a hypothesis-driven, experimental fashion, using a deck of cards. Our standard exercise is suitable for upper-level high school and introductory biology students at the college level. In this paper, we discuss the exercise in detail and give several examples that illustrate how our games provide accessible bridges to the primary literature. Finally, we discuss how extensions of our basic exercise can be used to effectively teach advanced evolutionary concepts.     

Hands-on training about overfitting

Overfitting is one of the critical problems in developing models by machine learning. With machine learning becoming an essential technology in computational biology, we must include training about overfitting in all courses that introduce this technology to students and practitioners. We here propose a hands-on training for overfitting that is suitable for introductory level courses and can be carried out on its own or embedded within any data science course. We use workflow-based design of machine learning pipelines, experimentation-based teaching, and hands-on approach that focuses on concepts rather than underlying mathematics. We here detail the data analysis workflows we use in training and motivate them from the viewpoint of teaching goals. Our proposed approach relies on Orange, an open-source data science toolbox that combines data visualization and machine learning, and that is tailored for education in machine learning and explorative data analysis.     

How fieldwork-oriented biology teachers establish formal outdoor education practices

ABSTRACT

Fieldwork is an important part of biology as well as science and biology education. However, teachers perceive several reasons for the limited use of fieldwork in schools. Further, outdoor education is often organised as a single fieldtrip guided by outdoor educators, and little research has been done on fieldwork as a regular part of formal biology education. This case study explores three secondary-school biology teachers who untypically use outdoor education as a major part of their ecology courses for 8^th grade students (median age 14). Berger and Luckmann’s theory of the process of institutionalization as a theoretical background is used to interpret the pedagogical and organizational choices of the case study teachers. Analysis of the interviews of the selected three teachers revealed pedagogical and organizational means through which outdoor teaching is institutionalized into a regular activity in biology lessons. The teachers considered regularity, assessment practices and the school curriculum as major tools to legitimate outdoor learning as a formal schoolwork and foster successful learning. However, they also emphasised students’ freedom during outdoor activities. The findings are discussed in terms of how the teachers succeeded in combining the institutional order of formal schooling with students’ freedom in nature.     

Educational Malpractice: The Impact of Including Creationism in High School Biology Courses

College students whose recollections of their high school biology courses included creationism were significantly more likely to invoke creationism-based answers on questions derived from the Material Acceptance of the Theory of Evolution (MATE) instrument than were students whose recollections of their high school biology courses included evolution but not creationism. On average, students who were taught neither evolution nor creationism in their high school biology courses exhibited intermediary responses on the MATE instrument. These results suggest that (1) high school teachers’ treatments of evolution and creationism have a lasting impact and (2) the inclusion of creationism in high school biology courses increases the probability that students accept creationism and reject evolution when they arrive at college. These results are discussed relative to the impact of high school biology courses on students’ subsequent acceptance of evolution and creationism.     

Evolution and nature of science instruction

In this article, I provide an analysis of my work (1985–present) with non-major biology students and science teacher candidates in developing strategies for teaching and enhancing learning with respect to evolutionary science. This first-person account describes changes in evolution instruction over the course of a career based on personal experiences, research-informed practices, and a critical collaboration with colleague Mike U. Smith. I assert four insights concerning the influence and efficacy of teaching nature of science (NOS) prior to the introduction of evolution within college courses for science non-majors and science teacher candidates. These insights are: (a) teach explicit NOS principles first; (b) integrate evolution as a theme throughout a course in introductory biology (but after NOS principles have been introduced); (c) use active learning pedagogies; and (d) use non-threatening alternative assessments to enhance student learning and acceptance of evolutionary science. Together, these insights establish a pedagogy that I (and my colleagues) have found to be efficacious for supporting novice students as they engage in the study of evolutionary science.     

Student‐led field studies of herbivory: Hands‐on experiences for remote (or in‐person) learning

Challenging students to independently design and implement experiments is a powerful way to teach the scientific method while engaging with STEM‐related course material. For ecology and organismal biology, such experiences often take the form of field work. The COVID‐19 pandemic presented formidable challenges for instructors of such courses: How can students conduct any experiments, much less ones of their own design, when they might not even have access to campus? Here we describe a student‐led field project exploring invertebrate herbivory in terrestrial plant systems. Designed to flexibly accommodate student groups working either in‐person, remotely, or both, the project would be suitable for invertebrate biology, plant biology, or general ecology courses at the college or high school level. We describe our implementation in two sections of a sophomore‐level course, provide specific advice based on our experiences, make suggestions for future improvements or adaptations, and provide all the written materials that instructors would need to implement this in their own teaching.     

The University of Alabama at Birmingham Center for Community OutReach Development Summer Science Institute Program: a 3-yr laboratory research experience for inner-city secondary-level students

This article describes and assesses the effectiveness of a 3-yr, laboratory-based summer science program to improve the academic performance of inner-city high school students. The program was designed to gradually introduce such students to increasingly more rigorous laboratory experiences in an attempt to interest them in and model what "real" science is like. The students are also exposed to scientific seminars and university tours as well as English and mathematics workshops designed to help them analyze their laboratory data and prepare for their closing ceremony presentations. Qualitative and quantitative analysis of student performance in these programs indicates that participants not only learn the vocabulary, facts, and concepts of science, but also develop a better appreciation of what it is like to be a "real" scientist. In addition, the college-bound 3-yr graduates of this program appear to be better prepared to successfully academically compete with graduates of other high schools; they also report learning useful job-related life skills. Finally, the critical conceptual components of this program are discussed so that science educators interested in using this model can modify it to fit the individual resources and strengths of their particular setting.     

Instructors' practices in and attitudes toward teaching ethics in the genetics classroom

There is strong consensus among educators that training in the ethical and social consequences of science is necessary for the development of students into the science professionals and well-rounded citizens needed in the future. However, this part of the curriculum is not a major focus of most science departments and it is not clear if, or how, students receive this training. To determine the current status of bioethics education of undergraduate biology students in the United States, we surveyed instructors of introductory genetics. We found that there was support for more ethics education both in the general curriculum and in the genetics classroom than is currently being given. Most instructors devote <5% of class time to ethical and social issues in their genetics courses. The majority feels that this is inadequate treatment of these topics and most cited lack of time as a major reason they were unable to give more attention to bioethics. We believe biology departments should take the responsibility to ensure that their students are receiving a balanced education. Undergraduate students should be adequately trained in ethics either within their science courses or in a specialized course elsewhere in the curriculum.     

Advanced high school biology in an era of rapid change: a summary of the biology panel report from the NRC Committee on Programs for Advanced Study of Mathematics and Science in American High Schools

A recently released National Research Council (NRC) report, Learning and Understanding: Improving Advanced Study of Mathematics and Science in U.S. High Schools, evaluated and recommended changes in the Advanced Placement (AP), International Baccalaureate (IB), and other advanced secondary school science programs. As part of this study, discipline-specific panels were formed to evaluate advanced programs in biology, chemistry, physics, and mathematics. Among the conclusions of the Content Panel for Biology were that AP courses in particular suffer from inadequate quality control as well as excessive pressure to fulfill their advanced placement function, which encourages teachers to attempt coverage of all areas of biology and emphasize memorization of facts rather than in-depth understanding. In this essay, the Panel's principal findings are discussed, with an emphasis on its recommendation that colleges and universities should be strongly discouraged from using performance on either the AP examination or the IB examination as the sole basis for automatic placement out of required introductory courses for biology majors and distribution requirements for nonmajors.     

Evolving strategies for the incorporation of bioinformatics within the undergraduate cell biology curriculum

Recent advances in genomics and structural biology have resulted in an unprecedented increase in biological data available from Internet-accessible databases. In order to help students effectively use this vast repository of information, undergraduate biology students at Drake University were introduced to bioinformatics software and databases in three courses, beginning with an introductory course in cell biology. The exercises and projects that were used to help students develop literacy in bioinformatics are described. In a recently offered course in bioinformatics, students developed their own simple sequence analysis tool using the Perl programming language. These experiences are described from the point of view of the instructor as well as the students. A preliminary assessment has been made of the degree to which students had developed a working knowledge of bioinformatics concepts and methods. Finally, some conclusions have been drawn from these courses that may be helpful to instructors wishing to introduce bioinformatics within the undergraduate biology curriculum.     

The Lego® analogy model for teaching gene sequencing and biotechnology

Research in biotechnology is rapidly advancing; everyday, new and exciting discoveries are made. With this new technology there are also many safety and ethical questions, though, as well as the need for education. Alternative teaching methods may help to increase students' understanding of difficult concepts in all aspects of schooling, including mathematics, science, genetics, and biotechnology. The Genomic Analogy Model for Educators (GAME) is a teaching tool currently under development, made up of three different pieces: (i) a CD-Rom, (ii) a website and (iii) laboratory exercises. The GAME model uses simple analogies of easily understandable concepts to explain the technical and scientific aspects of modern genomics; the first module is the Lego® Analogy Model (LAM) which focuses on DNA sequencing using the Sanger method and electrophoresis. The purpose of this study was to evaluate the effectiveness of the GAME model on high school students. In addition, the short term effect of the GAME model on high school students' attitudes about biotechnology was also measured. Results showed a positive change in students' post-test scores after participating in GAME which indicates the effectiveness of this new tool for biotechnology education.     

Does the Segregation of Evolution in Biology Textbooks and Introductory Courses Reinforce Students’ Faulty Mental Models of Biology and Evolution?

The well-established finding that substantial confusion and misconceptions about evolution and natural selection persist after college instruction suggests that these courses neither foster accurate mental models of evolution’s mechanisms nor instill an appreciation of evolution’s centrality to an understanding of the living world. Our essay explores the roles that introductory biology courses and textbooks may play in reinforcing undergraduates’ pre-existing, faulty mental models of the place of evolution in the biological sciences. Our content analyses of the three best-selling introductory biology textbooks for majors revealed the conceptual segregation of evolutionary information. The vast majority of the evolutionary terms and concepts in each book were isolated in sections about evolution and diversity, while remarkably few were employed in other sections of the books. Standardizing the data by number of pages per unit did not alter this pattern. Students may fail to grasp that evolution is the unifying theme of biology because introductory courses and textbooks reinforce such isolation. Two goals are central to resolving this problem: the desegregation of evolution as separate “units” or chapters and the active integration of evolutionary concepts at all levels and across all domains of introductory biology.
