The Effects Of An Early Intervention Mastery Activity In The Mathematics Department, Nathan Wakefield, Joe Champion, Doug Dailey, Jessalyn Bolkema

DBER Speaker Series

At the University of Nebraska-Lincoln, nearly 1000 students sign up for one of College Algebra, or College Algebra and Trigonometry every fall. Of these students, more than 75% are first time freshman. Finding ways to motivate and encourage these students together with early identification strategy for struggling students is critical to success not just in the math course, but also in a student’s university career. This presentation will discuss the design and outcomes an early intervention mastery activity with the broad goals of helping students recall previously learned mathematics, and identifying students who are at risk for failure, all within …

Climate Change Skeptics Teach Climate Literacy? A Content Analysis Of Children’S Books, Julie Thomas

DBER Speaker Series

This research focused on skeptical climate change literature designed for children and parents. The purpose of the research was to explore how these pseudo‐educational materials convey a logic of nonproblematicity about climate change (McCright & Dunlap, 2000). Using rhetorical analyses procedures developed from previous excavations in skeptical discourses, this study identified: (a) common forms of climate skepticism, (b) frames for climate change policy making, (c) areas of contested scientific knowledge, and (d) appeals for managing the uncertainty of climate change. The results suggest that the logic of non‐problematicity about environmental problems is bolstered by contradictory forms of climate change skepticism …

Engaging Teenagers With Science Through Comics, Judy Diamond

DBER Speaker Series

Graphic novels or comics are powerful tools to motivate youth to become interested in science. Embedding science concepts into a story with graphics that appeal to teen culture makes abstract content approachable, stimulates youth interest, and promotes learning. This presentation will discuss the goals of the NIH‐funded World of Viruses and Biology of Human comic series and the research results that support using these approaches.

Is It Still Science If You Don’T Call It ‘Science’? Discovery Orientation And Science Identity Among Middle School Youth., Patricia Wonch Hill, Julia Mcquillan

DBER Speaker Series

To investigate the role of friendships in science identity formation, we are conducting a longitudinal survey of 441 students in an ethnically diverse Title I Middle School. This research-based approach, framed within a sociological conceptual model, will provide depth in our understanding of how to motivate and engage youth from groups underrepresented in biomedical science, and will contribute to the sociological literature on identity formation. Science educators assume most youth have a natural propensity toward science and inquiry, and will engage with science activities and ideas if they are presented in fun and appealing ways. We call this natural propensity …

Vehicles On The Road To Reform, Julie Thomas, Sandra B. Cooper

DBER Speaker Series

Though elementary teacher educators introduce new, reform‐based strategies in science and mathematics methods courses, researchers wondered how novices negotiate reform strategies once they enter the elementary school culture. Given that the extent of parents’ and veteran teachers’ influence on novice teachers is largely unknown, this grounded theory study explored parents’ and teachers’ expectations of children’s optimal science and mathematics learning in the current era of reform. Data consisted of semi‐structured, open‐ended interviews with novice teachers (n=20), veteran teachers (n=9), and parents (n=28). Researchers followed three stages of coding procedures to develop a logic model connecting participants’ discrete designations of the …

The Mindful Learning Model, David W. Brooks, Guy Trainin, Khalid Sayood

DBER Speaker Series

Earlier we published the Unified Learning Model which speaks to learning based on achieieving the "top slot" in working memory, repetition, and connections. The Mindful Learning Model accounts for more recent understandings of learning, and especially connections to "consciousness." The model has many parts. Inputs to the brain from sensors (eyes, ears) are not so much information about what is perceived but about discrepancies between that perception and one's mental model of the current context. The voices in our heads are after‐the fact reports rather than realtime executives. Working memory is a series of detectable brain events taking place over …

Pre‐Service Teachers’ Use Of Content Knowledge To Inform Formative Assessment Strategies In An Integrated Life Sciences Methods Course, Jaime Sabel, Cory Forbes

DBER Speaker Series

Pre‐service elementary teachers should learn essential science concepts, how to apply those concepts to practice in elementary science learning environments, and how to effectively connect students’ ideas to appropriate instructional strategies. In order to effectively engage students in scientific practices and connect students’ ideas about science to appropriate instructional strategies, teachers should learn to engage in high‐leverage instructional practices, such as formative assessment. However, teachers may not understand formative assessment or possess enough science content knowledge to effectively engage in related instructional practices. To address these needs, we developed an innovative course for elementary pre‐service teachers built upon two pillars—life …

Systems Thinking With Biology Models, Joseph Dauer

DBER Speaker Series

The recent AAAS call to improve undergraduate biology education suggested university instruction should focus on teaching core concepts like matter and energy, evolution, and systems and core competences like quantitative reasoning, modeling and integrating disciplines. My research has focused on how undergraduate biology students organize their knowledge of biological systems and how they reason about the myriad interactions and potential outcomes inherent to these systems. I will report ongoing research into students’ model construction during an introductory biology course and during clinical interviews 2 years after the course. My colleagues and I have found students’ models change dramatically in both …

Student Retention In Stem: Exploration Of The Gender Gap, Olha Ketsman, Carolina C. Ilie

DBER Speaker Series

Prior research indicates that there are small numbers of women in STEM areas and in physics in particular; the latter may suggest that women who have potential to contribute to physics choose other careers. This presentation examines the gender gap in STEM with a focus on physics. We discuss a that was survey administered to undergraduate science students at one primarily undergraduate college in the United States, the factors that impacted student decisions in physics, and recommendations to increase student retention.

Elements: Elementary Teachers Of Science – Building Collaborations Between Content And Pedagogy Communities, Krista Adams, Jenny Melander

DBER 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

DBER 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

DBER 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

DBER 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 …

Creating Interdisciplinary Collaborations To Support And Understand Mathematics Teaching And Learning, Ruth Heaton, Wendy M. Smith, Traci Kutaka

DBER 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

DBER 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 …

The History And Impact Of A College‐Level Field‐Based Course On Learner And Community Development, David M. Harwood, Leilani Arthurs

DBER Speaker Series

Providing students with inquiry‐based learning experiences was a key recommendation made in the National Academies' 2007 report, Rising Above the Gathering Storm: Energizing and Employing America for a Brighter Economic Future, and this presentation is about a model for providing such experiences to college‐level students through a field‐based geology course. GEOL 160 – Fundamentals of Geosciences in the Field was developed 10 years ago for undergraduate students preparing to be K‐12 science teachers. The goals of the course are to enhance undergraduate pre‐service science teachers’ (i) knowledge of geoscience and the nature of science, (ii) attitudes about science, and (iii) …

Young Children’S Understanding Of Conservation Concepts, Julia C. Torquati

DBER Speaker Series

This presentation will summarize an investigation of young children’s conservation knowledge and reasoning. Eighty‐two preschool aged children (3‐5 years) were interviewed at two points in time six months apart using a semi‐structured interview. The interview protocol developed by Peter Kahn (2001) was used to assess children’s conservation attitudes. This was the first time the interview was used with preschool aged children. Children were asked questions about the importance of animals, plants, parks, and gardens, and whether it is acceptable to litter (and why or why not). Fifty‐seven of the children attended a preschool located at a nature center, ten children …

Concept Inventory Design For Determining Students’ Conceptual Understanding Of Oceanography, Leilani Arthurs

DBER Speaker Series

Concept inventories are relatively new types of diagnostic instruments intended to measure student learning. Concept inventories exist for astronomy, biology, chemistry, engineering, fluid mechanics, geology, and physics. None is yet available for oceanography, and development of the Introductory Oceanography Concept Inventory Survey (IO‐CIS) serves to fill this gap. A context‐driven development strategy was designed to create this instrument. Qualitative methods utilizing grounded theory and classical test theory were used to construct it. Quantitative methods, including statistical methods associated with classical test theory and item response theory, were used to evaluate and further refine the IO‐CIS. The instrument is valid and …
