How Administration Stakes And Settings Affect Student Behavior And Performance On A Biology Concept Assessment, Crystal Uminski, Joanna K. Hubbard, Brian A. Couch

School of Biological Sciences: Faculty Publications

Biology instructors use concept assessments in their courses to gauge student understanding of important disciplinary ideas. Instructors can choose to administer concept assessments based on participation (i.e., lower stakes) or the correctness of responses (i.e., higher stakes), and students can complete the assessment in an in-class or out-of-class setting. Different administration conditions may affect how students engage with and perform on concept assessments, thus influencing how instructors should interpret the resulting scores. Building on a validity framework, we collected data from 1578 undergraduate students over 5 years under five different administration conditions. We did not find significant differences in scores …

A Collection Of Calculus Lesson Plans: Deriving The 'Why' Behind Derivatives, Kasey Brabec

Honors Program: Senior Projects (Public)

The traditional mathematics classroom is led with a focus on procedural understanding, with deep conceptual understanding considered to be unimportant or too difficult to teach within the allotted time. Both levels of understanding are important mathematical competencies, as it is rare for either of them to function well without accessibility to the other. The disparity between conceptual understanding and procedural understanding in the mathematics classroom is no larger than in courses like Calculus. This project is a collection of fifteen lesson plans constructed with an emphasis on conceptual understanding and the connectivity of Calculus. Each lesson plan’s overview contains the …

Comparison Of Rural And Urban High School Science And Engineering Integration In Two School Districts, Elizabeth Hasseler, Elizabeth B. Lewis

Department of Teaching, Learning, and Teacher Education: Faculty Publications

A comparative case study was conducted in an urban and rural district, focusing on how science and engineering were integrated into the high school programs. This led to the recommendation for districts to provide collaboration and mentorship opportunities that support teachers integrating engineering into their classrooms.

Next Generation Science Standards* Crosscutting Concept 4. Systems and system models. A system is an organized group of related objects or components; models can be used for understanding and predicting the behavior of systems.

Youth will identify components of network graphs and interpret relationships modeled by the network graphs. They will develop curiosity (ask questions) about why there are connections in some places and not in other places; why there are different colors; shapes, and sizes, and how/if the model helps us understand the phenomenon.

Nebraska Voices Survey Methodology Report; Including Missing Data Handling And Creating A Raked Weight Variable Using Iterative Proportional Fitting, Joseph C. Jochman, Julia Mcquillan, Grace Kelly, Patricia Wonch Hill, Meghan Leadabrand

To gain a comprehensive picture of the surveys that this methodology report references, see the Bureau of Sociological Research methodology reports for each survey available at this link. In the original survey reports the Bureau of Sociological Research staff provide descriptions of data collection, sampling and questionnaire design, response rate, data processing, and preliminary data cleaning. Introduction This report outlines the process of creating a raked weight variable for the NebrASKa Voices 2020 survey, a second “Wave 2” survey following four different “Wave 1” surveys. The 2020 NebrASKa Voices sample Wave 1 prior Nebraska Annual Social Indicators Surveys (NASIS) come …

Decline Is Not Inevitable: Changes In Science Identity During The Progression Through A U.S. Middle School Among Boys And Girls, Julia Mcquillan, Patricia Wonch Hill, Joseph C. Jochman, Grace Kelly

Worlds of Connections Resources

In the United States, science capital is important for navigating many aspects of life. Yet during middle school, science interest declines more for girls than boys. It is unclear, however, whether science identity also declines during the middle school years and if there are differences by gender. The authors advance prior research by modeling changes in science identity and associations with changes in identity-relevant characteristics using growth curve analyses on four waves of data from 760 middle school youth. For girls and boys, science identity changes over time; about 40 percent of the variance is within-person change, with the remainder …

Youth will understand and demonstrate the importance of building and recognizing connections in a community. They will make a network model that reveals connections that may seem invisible until youth trace them. Youth will learn about the concept of ‘six degrees of separation/small worlds’ (i.e., how we may be connected to people far away through our friends’ friends).

Entomology Outreach Presentations To Four Audiences, Michael Goldman

Department of Entomology: Distance Master of Science Projects

I proposed that my master’s Project would be outreach on Entomology at four levels: School aged children, laymen, non-entomologists in a technical field, and entomologists. The idea here is basically how to talk about entomology to varying levels of expertise, from first graders to experts in both entomology and occupational health and safety. Presentations were given to audiences at each of the four levels. The specific topics varied for each audience. The determination was made by the inviting audience in the cases of school aged children and adult laymen and by me in the cases of Occupational Safety and Health …

Using Drawing As A Tool For Investigating Undergraduate Conceptions Of Earth Scientists, Peggy Mcneal, Deepika Menon, Deef Allah Al Shorman, Paulina Gajewska-Schaefer

Department of Teaching, Learning, and Teacher Education: Faculty Publications

The purpose of this study was to investigate undergraduate students’ conceptions of Earth scientists, using drawing as a tool, during introductory Earth science courses. We explored two research questions: 1) What student conceptions are evident in undergraduate students’ drawings of Earth scientists? and 2) How do undergraduate students’ conceptions of Earth scientists—as evidenced in their drawings—change as a result of completing an introductory Earth science course? We collected pre- and post-drawings of Earth scientists from 94 students in six introductory Earth science courses at two universities and coded the 188 drawings across 39 indicators. We used Chi Square Goodness of …

Preservice Elementary Teachers Conceptions And Self-Efficacy For Integrated Stem, Deepika Menon, Deef A. A. Shorman, Derek Cox, Amanda Thomas

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Educational reform efforts have emphasized preparing highly competent and confident preservice teachers to deliver effective K-12 Science, Technology, Engineering, and Mathematics (STEM) instruction. Self-efficacy is a key variable that influences motivation and performance, and therefore it is necessary to support the development of preservice teachers’ integrated STEM teaching self-efficacy. This mixed-methods study investigates how preservice elementary teachers’ integrated STEM teaching self-efficacy is shaped during their participation in a newly redesigned STEM semester consisting of three concurrent methods courses (science and engineering, mathematics, and technology methods courses). The quantitative data sources included the Self-efficacy for Teaching Integrated STEM instrument administered as …

Discoverinsects.Com: An Interactive Tool To Introduce Younger Audiences To Entomology, Ian Eldred

Department of Entomology: Distance Master of Science Projects

Early in life, children’s views towards arthropods can be tainted by many things. One major way is through the views held and expressed by those that surround them, especially their caregivers. Tools are needed to reach children during these crucial developmental ages and expose them to all of the wonderful things arthropods do and educate them on how big of a role arthropods play in the lives of every human around the globe. As digital technology in households is becoming more apparent and accessible, new ways to engage these audiences need to be developed and utilized. This creates a unique …
