Why American Higher Education Needs Parasitologists, John J. Janovy Jr.
Why American Higher Education Needs Parasitologists, John J. Janovy Jr.
John J. Janovy, Jr. Publications
Addresses four topics that characterize the discipline of parasitology and are largely missing from our national conversation in the United States about education, especially at the college and university level. Those topics are the production of transferable skills; our perceptions of the world, especially the natural world; access to reasonably difficult problems in natural settings; and intellectual epidemiology, or the movement of ideas, innovations, and cultural items through populations. These topics have been a part of the author's discussions with fellow parasitologists for at least half a century, beginning with his choice to pursue a graduate degree under the supervision …

School of Biological Sciences: Faculty Publications
As the frontiers of biology become increasingly interdisciplinary, the physics education community has engaged in ongoing efforts to make physics classes more relevant to life science majors. These efforts are complicated by the many apparent differences between these fields, including the types of systems that each studies, the behavior of those systems, the kinds of measurements that each makes, and the role of mathematics in each field. Nonetheless, physics and biology are both sciences that rely on observations and measurements to construct models of the natural world. In this article, we propose that efforts to bridge the teaching of these …

Elements: Elementary Teachers Of Science – Building Collaborations Between Content And Pedagogy Communities, Krista Adams, Jenny Melander
Discipline-Based Education Research Group Speaker Series
The current UNL elementary teaching program does not include a science methods practicum in which pre‐service elementary teachers could observe and teach reformed based science lessons in the classroom setting. The science methods course was modified during Spring 2013 to address this missing component. The exploratory course engages pre‐service teachers in designing and implementing a science unit (a series of lessons) to be taught as a science club in an after school program for K – 5th grade students. In Fall 2013, the course experiences expanded to include collaborating with biomedical engineering students in connecting real‐world applications to teaching science. …

Educating Highly‐Qualified Science Teachers, Elizabeth Lewis, Aaron A. Musson, Jia Lu
Discipline-Based Education Research Group Speaker Series
Understanding what makes a highly‐qualified science teacher requires careful research on teacher education programs. Existing research pertaining to secondary science preservice teachers (PSTs) is limited in the areas of: (a) mastery of subject matter knowledge; (b) evolving teaching selfefficacy, and (c) inquiry‐based enacted curricular practices. We studied each issue over the course of an intensive, 14‐month, graduate teacher certification program for practicing scientists and recent science graduates. First, we asked if there was a relationship between amount of content area undergraduate coursework and performance (GPA in core content courses) and found an expected, yet preliminary, connection between higher undergraduate GPA …

An Examination Of How Women And Underrepresented Racial/Ethnic Minorities Experience Barriers In Biomedical Research And Medical Programs, Devasmita Chakraverty
Discipline-Based Education Research Group Speaker Series
Women in medicine and biomedical research often face challenges to their retention, promotion, and advancement to leadership positions (McPhillips et al., 2007); they take longer to advance their careers, tend to serve at less research‐intensive institutions and have shorter tenures compared to their male colleagues (White, McDade, Yamagata, & Morahan, 2012). Additionally, Blacks and Hispanics are the two largest minority groups that are vastly underrepresented in medicine and biomedical research in the United States (AAMC, 2012; NSF, 2011). The purpose of this study is to examine specific barriers reported by students and post‐degree professionals in the field through the following …
Question Order Effects On A General Chemistry Concept Inventory, Travis Lund
Question Order Effects On A General Chemistry Concept Inventory, Travis Lund
Discipline-Based Education Research Group Speaker Series
During the development of a general chemistry concept survey, interviews demonstrated that students used distinctly different problem‐solving strategies to answer two survey questions, one verbally‐based and one pictorially‐based, despite the fact that the questions were both designed to test the same concept of strong versus weak acids. Alternate versions of the concept survey were administered, with the order of the pictorial and verbal questions reversed. A significant ordering effect was observed in the questions of interest, and the incorrect answer choices that became better or worse distractors were identified. Current findings, future directions, and practical implications for instructors and researchers …

Department of Entomology: Faculty Publications
Publication of the 1996 National Science Education Standards (NSES) initiated a push to transform science education by engaging K-12 students in active learning through inquiry-based teaching (National Research Council, 1996). Students need opportunities to construct knowledge by asking questions, developing hypotheses, collecting and analyzing data, and interpreting and communicating results. Inquiry teaching has been shown to improve students’ attitudes toward science, enhance their performance, and promote scientific literacy (Haury, 1993; Lindberg, 1990: Mattheis and Nakayama, 1988; Rakow, 1986).
Providing both pre- and in-service teachers with courses and professional development programs that promote inquiry teaching are vital to teacher education (National …

Creating Interdisciplinary Collaborations To Support And Understand Mathematics Teaching And Learning, Ruth Heaton, Wendy M. Smith, Traci Kutaka
Discipline-Based Education Research Group Speaker Series
Teaching mathematics is a complex endeavor and requires a deep understanding of content and pedagogy. Helping teachers learn what they need to know requires the expertise of disciplinary area faculty as well as those with pedagogical expertise. Similarly, understanding the learning of teachers or their students requires complex analyses of messy data by teams of researchers representing differing but complementary perspectives. Cases describing the nature and process of interdisciplinary teaching and research collaborations in mathematics education will be presented and analyzed for lessons learned.
Transformations In Matter And Energy: Student Learning And Inquiry To Inform Teaching, Jenny Dauer
Transformations In Matter And Energy: Student Learning And Inquiry To Inform Teaching, Jenny Dauer
Discipline-Based Education Research Group Speaker Series
Learning progressions are descriptions of increasing levels of sophistication of student reasoning about a topic based on empirical evidence. Our learning progression framework about student explanations of carbon-transforming processes (e.g. photosynthesis, cellular respiration) describes how student’s interconnected and mutually supporting ideas and practices are deeply embedded in discourse at all levels of achievement. My research is in two areas: 1) applying the learning progression framework for student explanations of carbon-transforming processes to describe the most productive pathways for student learning, 2) extending the research to student reasoning during inquiry activities about carbon-transforming processes. One finding is that students who consistently …

Comparability Of Online And Paper/Pencil Mathematics Performance Measures, John L. Moon
College of Education and Human Sciences: Dissertations, Theses, and Student Research
The purpose of this study was to investigate the relationship between student mathematics performance of 4th, 8th, and 11th grade students in Nebraska and the mode of test administration, online and paper-pencil. Schools were allowed to select the mode of test administration for their school with some exceptions for students needing accommodations. This resulted in four test groups, namely students taking the online tests in schools selecting paper or online assessments along with students taking the paper-pencil tests in schools selecting paper or online assessments. Since the students in the study were clustered within schools, …

Department of Chemistry: Faculty Publications
Innovative, research-based instructional practices are critical to transforming the conventional undergraduate instructional landscape into a student-centered learning environment. Research on dissemination of innovation indicates that instructors often adapt rather than adopt these practices. These adaptations can lead to the loss of critical elements of the practice, which may affect its effectiveness. Process-oriented, guided-inquiry learning (POGIL) is a research-based instructional practice that has been widely disseminated for the past two decades. However, few studies have investigated practitioners’ adaptations of POGIL and the impact of these adaptations on expected outcomes measured during recommended implementations of POGIL. In this study, we explore the …

Fostering Student Sense Making In Elementary Science Learning Environments: Elementary Teachers’ Use Of Science Curriculum Materials To Promote Explanation Construction, Laura Zangori, Cory Forbes, Mandy Biggers
Fostering Student Sense Making In Elementary Science Learning Environments: Elementary Teachers’ Use Of Science Curriculum Materials To Promote Explanation Construction, Laura Zangori, Cory Forbes, Mandy Biggers
School of Natural Resources: Faculty Publications
While research has shown that elementary (K-5) students are capable of engaging in the scientific practice of explanation construction, commonly-used elementary science curriculum materials may not always afford them opportunities to do so. As a result, elementary teachers must often adapt their science curriculum materials to better support students’ explanation construction and foster student sense making. However, little research has been conducted to explore if and, if so, how and why, elementary teachers modify science curriculum materials to engage students in explanation construction. We use an embedded mixed methods research design to explore elementary teachers’ (n = 45) curricular adaptations …

The Mathematical Development In Number And Operation Of Struggling First Graders, John Lannin, Delinda Van Garderen, Matthew J. Switzer, Kelley E. Buchheister, Tiffany Hill, Christa Jackson
Department of Child, Youth, and Family Studies: Faculty Publications
Number and operations serve as the “cornerstone” of the K-12 mathematics curriculum in many countries. Solving problems in the mathematical domains of algebra, geometry, measurement, and statistics is often closely connected to student knowledge of number and operation (Griffin, 2005). Although considerable knowledge exists regarding the development of number and operation for typically developing children, less is known about the development of children who struggle in mathematics. Moreover, children enter school with considerable differences in their understanding of number and operation. While most children, through exposure to various informal and formal tasks, develop a deeper understanding of number and operation, …

Theory Guided Professional Development In Early Childhood Science Education, Soo-Young Hong, Julia C. Torquati, Victoria J. Molfese
Nebraska Center for Research on Children, Youth, Families, and Schools: Faculty Publications
The importance of early and developmentally appropriate science education is increasingly recognized. Consequently, creation of common guidelines and standards in early childhood science education has begun (National Research Council (NRC), 2012), and researchers, practitioners, and policy makers have shown great interest in aligning professional development with the new guidelines and standard. There are some important issues that need to be addressed in order to successfully implement guidelines and make progress toward accomplishing standards. Early childhood teachers have expressed a lack of confidence in teaching science and nature (Torquati, Cutler, Gilkerson, & Sarver, in press) and have limited science and pedagogical …
