Although undergraduates have long held a role as teaching assistants for introductory science courses at liberal arts colleges and universities, educational institutions often do not provide these students with opportunities to explore science teaching and pedagogy. At Brandeis University, we designed an internship course to help increase the motivation, understanding, and knowledge of teaching pedagogy for undergraduate teaching assistants that is offered concurrently with their teaching responsibilities. Weekly sessions with faculty mentors are guided by readings in current science education literature, and throughout the semester students are asked to develop new course material based on the pedagogical frameworks discussed. To evaluate the effectiveness of this course, we surveyed students at the close of the semester. We found an overall increase in student confidence levels with regard to teaching and better awareness of the difficulties faced in science education. All students who participated in the course expressed interest in participating in future educational internships. We believe that the Educating Young Educators internship has the potential to be a catalyst for personal and professional growth from a novice into an informed young educator.

Natural selection is one of the most important concepts for biology students to understand, but students frequently have misconceptions regarding how natural selection operates. Many of these misconceptions, such as a belief in “Lamarckian” evolution, are based on a misunderstanding of inheritance. In this essay, we argue that evolution instructors should clarify the genetic basis of natural selection by discussing examples of DNA sequences that affect fitness. Such examples are useful for showing how natural selection works, for establishing connections between genetics and evolution, and for creating cognitive conflict within students having misconceptions. We describe several examples of genes that instructors might use during lectures, and present preliminary evidence from our classroom that an evolution curriculum rich in DNA sequences is effective at reducing student misconceptions of natural selection.

This completely computer-based module's purpose is to introduce students to bioinformatics resources. We present an easy-to-adopt module that weaves together several important bioinformatic tools so students can grasp how these tools are used in answering research questions. Students integrate information gathered from websites dealing with anatomy (Mouse Brain Library), quantitative trait locus analysis (WebQTL from GeneNetwork), bioinformatics and gene expression analyses (University of California, Santa Cruz Genome Browser, National Center for Biotechnology Information's Entrez Gene, and the Allen Brain Atlas), and information resources (PubMed). Instructors can use these various websites in concert to teach genetics from the phenotypic level to the molecular level, aspects of neuroanatomy and histology, statistics, quantitative trait locus analysis, and molecular biology (including in situ hybridization and microarray analysis), and to introduce bioinformatic resources. Students use these resources to discover 1) the region(s) of chromosome(s) influencing the phenotypic trait, 2) a list of candidate genes—narrowed by expression data, 3) the in situ pattern of a given gene in the region of interest, 4) the nucleotide sequence of the candidate gene, and 5) articles describing the gene. Teaching materials such as a detailed student/instructor's manual, PowerPoints, sample exams, and links to free Web resources can be found at http://mdcune.psych.ucla.edu/modules/bioinformatics.

Undergraduate research experiences have been shown to enhance the educational experience and retention of college students, especially those from underrepresented populations. However, many challenges still exist relative to building community among students navigating large institutions. We developed a novel course called Entering Research that creates a learning community to support beginning undergraduate researchers and is designed to parallel the Entering Mentoring course for graduate students, postdocs, and faculty serving as mentors of undergraduate researchers. The course serves as a model that can be easily adapted for use across the science, technology, engineering, and mathematics (STEM) disciplines using a readily available facilitator's manual. Course evaluations and rigorous assessment show that the Entering Research course helps students in many ways, including finding a mentor, understanding their place in a research community, and connecting their research to their course work in the biological and physical sciences. Students in the course reported statistically significant gains in their skills, knowledge, and confidence as researchers compared with a control group of students, who also were engaged in undergraduate research but not enrolled in this course. In addition, the faculty and staff members who served as facilitators of the Entering Research course described their experience as rewarding and one they would recommend to their colleagues.

We report on an outcomes assessment of the Summer Undergraduate Research Experience (SURE) Program at Emory University in Atlanta, GA. Using follow-up survey data and academic transcripts, we gauge SURE's impact on levels of interest in, preparedness for, and actual pursuit of graduate study and professional careers in the sciences for the program's first 15 summer cohorts (1990–2004). Our follow-up survey indicated significant increases in all research preparedness skills considered, notably in ability to give a poster research presentation, to discuss research at a graduate school interview, and to apply research ethics principles. About a third of SURE graduates went on to complete a graduate degree >90% considered SURE as important or very important in their academic development. Respondents reported postprogram increases in the level of interest in academic and research careers, and reported high levels of employment in science careers and job satisfaction. Regression analyses of Emory SURE participant transcripts revealed that participants take significantly more science courses as seniors and earn higher grades in those courses than nonparticipants. This trend held after correcting for indicators of prior interest (first-year course work, GPA, and math SAT scores), gender, and minority status. We also report on an external survey completed by SURE participants.

The use of personal response systems, or clickers, is increasingly common in college classrooms. Although clickers can increase student engagement and discussion, their benefits also can be overstated. A common practice is to ask the class a question, display the responses, allow the students to discuss the question, and then collect the responses a second time. In an introductory biology course, we asked whether showing students the class responses to a question biased their second response. Some sections of the course displayed a bar graph of the student responses and others served as a control group in which discussion occurred without seeing the most common answer chosen by the class. If students saw the bar graph, they were 30% more likely to switch from a less common to the most common response. This trend was more pronounced in true/false questions (38%) than multiple-choice questions (28%). These results suggest that observing the most common response can bias a student's second vote on a question and may be misinterpreted as an increase in performance due to student discussion alone.
