Ecoevo-Maps: An Ecology And Evolution Assessment For Introductory Through Advanced Undergraduates, Mindi M. Summers, Brian A. Couch, Jennifer K. Knight, Sara E. Brownell, Alison J. Crowe, Katharine Semsar, Christian D. Wright, Michelle K. Smith

School of Biological Sciences: Faculty Publications

A new assessment tool, Ecology and Evolution–Measuring Achievement and Progression in Science or EcoEvo-MAPS, measures student thinking in ecology and evolution during an undergraduate course of study. EcoEvo-MAPS targets foundational concepts in ecology and evolution and uses a novel approach that asks students to evaluate a series of predictions, conclusions, or interpretations as likely or unlikely to be true given a specific scenario. We collected evidence of validity and reliability for EcoEvo-MAPS through an iterative process of faculty review, student interviews, and analyses of assessment data from more than 3000 students at 34 associate’s-, bachelor’s-, master’s-, and doctoral-granting institutions. The …

What Types Of Instructional Shifts Do Students Experience? Investigating Active Learning In Science, Technology, Engineering, And Math Classes Across Key Transition Points From Middle School To The University Level, Kenneth Akiha, Emilie Brigham, Brain A. Couch, Justin Lewin, Marilyne Stains, Mackenzie R. Stetzer, Erin L. Vinson, Michelle K. Smith

School of Biological Sciences: Faculty Publications

Despite the need for a strong Science, Technology, Engineering, and Math (STEM) workforce, there is a high attrition rate for students who intend to complete undergraduate majors in these disciplines. Students who leave STEM degree programs often cite uninspiring instruction in introductory courses, including traditional lecturing, as a reason. While undergraduate courses play a critical role in STEM retention, little is understood about the instructional transitions students encounter upon moving from secondary to post-secondary STEM courses. This study compares classroom observation data collected using the Classroom Observation Protocol for Undergraduate STEM from over 450 middle school, high school, introductory-level university, …

Science At Engineer Cantonment, Hugh H. Genoways, Brett C. Ratcliffe, Carl R. Falk, Thomas E. Labedz, Paul R. Picha, John R. Bozell

University of Nebraska State Museum: Mammalogy Papers

Conclusions

It is our contention that Thomas Say, Titian Peale, Edwin James, and their colleagues of the Stephen Long Expedition of 1819–1820 were heavily engaged in scientific research, which took the form of the first biodiversity inventory undertaken in the United States. This accomplishment has been overlooked both by biologists and historians, but it should rank among the most significant accomplishments of the expedition. The results of this inventory continue to inform us today about environmental, faunal, and floral changes along the Missouri River in an area that is known to be an ecotone between the deciduous forests of the …

Student, Instructor, And Observer Agreement Regarding Frequencies Of Scientific Teaching Practices Using The Measurement Instrument For Scientific Teaching-Observable (Misto), Mary F. Durham, Jennifer Knight, Emily K. Bremers, Jameson D. Defreece, Alex R. Paine, Brian A. Couch

School of Biological Sciences: Faculty Publications

Background: The Scientific Teaching (ST) pedagogical framework encompasses many of the best practices recommended in the literature and highlighted in national reports. Understanding the growth and impact of ST requires instruments to accurately measure the extent to which practitioners implement ST in their courses. Researchers have typically relied on students, instructors, or observers to document course teaching practices, but it remains unclear whether and how these perspectives differ from each other. To address this issue, we modified our previously published instrument to generate the Measurement Instrument for Scientific Teaching-Observable (MISTO), which can be completed by students, instructors, and observers, and …

Seeing Mathematics Through Different Eyes: An Equitable Approach To Use With Prospective Teachers, Christa Jackson, Cynthia E. Taylor, Kelley Buchheister

Department of Child, Youth, and Family Studies: Faculty Publications

Teacher educators need to prepare prospective teachers by encouraging them to critically examine their current beliefs about the teaching and learning of mathematics while also providing opportunities for prospective teachers to develop an equity-centered orientation. Attending to these practices in teacher preparation programs may help prospective teachers observe actions that occur in classrooms and determine effective strategies that provide the opportunity to enhance all students’ access to high-quality mathematics instruction. As mathematics teacher educators, we must recognize what prospective teachers attend to as they direct their attention to various classroom events and how they relate the events to broader principles …

The Influence Of Previous Subject Experience On Interactions During Peer Instruction In An Introductory Physics Course: A Mixed Methods Analysis, Judy A. Vondruska

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Over the past decade, peer instruction and the introduction of student response systems has provided a means of improving student engagement and achievement in large-lecture settings. While the nature of the student discourse occurring during peer instruction is less understood, existing studies have shown student ideas about the subject, extraneous cues, and confidence level appear to matter in the student-student discourse. Using a mixed methods research design, this study examined the influence of previous subject experience on peer instruction in an introductory, one-semester Survey of Physics course. Quantitative results indicated students in discussion pairs where both had previous subject experience …

Bonding Ideas About Inquiry: Exploring Knowledge And Practices Of Metacognition In Beginning Secondary Science Teachers, Ana Margarita Rivero Arias

Department of Teaching, Learning, and Teacher Education: Theses and Other Student Research

Metacognition, identified generally as “thinking about thinking,” plays a fundamental role in science education. It enhances the understanding of science as a way to generate new knowledge using scientific concepts and practices. Moreover, metacognition supports the development of students’ life-long problem solving, collaboration, and critical thinking skills. When teachers use metacognition with intention, it can promote students’ agency and responsibility for their own learning. However, despite all of its benefits, metacognition is rarely seen in secondary science classrooms. Thus, it is important to understand what beginning teachers know and how they use metacognition during their first years in order to …

Beyond The City Lights: A Multiple-Case Study Of Successful, Experienced Secondary Science Teachers In Rural Schools, Beverly R. Devore-Wedding

Department of Teaching, Learning, and Teacher Education: Theses and Other Student Research

Recruitment and retention concerns for teachers, particularly in rural school districts and in science, fill the daily news and research literature. The shortage of STEM workers is also another concern as well. Then why do nationally recognized secondary science teachers remain in rural schools with lower salaries, increased responsibilities beyond teaching content, and multi-preparations, stay in those schools? How do they overcome challenges in their schools?

This multiple case study focuses on Presidential Award for Excellence in Mathematics and Science Teaching (PAEMST) awardees who have taught secondary science in rural school districts 10 years or more. Eight rural PAEMST high …

A Case Of Fragmented High School Earth And Space Science Education In The Great Plains: Tracing Teacher Certification Policy To Students' Access, Elizabeth B. Lewis, Jia Lu

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

While U.S. high school students’ access to Earth and space science (ESS) varies widely from state to state, nationally ESS content is the most neglected area of science education and scientific literacy. States have been considering if they will formally adopt, or less formally adapt, the new national science education standards, the Next Generation Science Standards (NGSS), which have been carefully developed and articulated in conjunction with state educational leaders. However, there are many challenges with which states, school districts, and teachers must grapple in order to enact standards-aligned ESS science lessons. This study of one Great Plains state investigated …

They will learn and help formulate practical strategies to reduce their negative impact in order …

How Question Types Reveal Student Thinking: An Experimental Comparison Of Multiple-True-False And Free-Response Formats, Joanna K. Hubbard, Macy A. Potts, Brian A. Couch

School of Biological Sciences: Faculty Publications

Assessments represent an important component of undergraduate courses because they affect how students interact with course content and gauge student achievement of course objectives. To make decisions on assessment design, instructors must understand the affordances and limitations of available question formats. Here, we use a crossover experimental design to identify differences in how multiple-true-false (MTF) and free-response (FR) exam questions reveal student thinking regarding specific conceptions. We report that correct response rates correlate across the two formats but that a higher percentage of students provide correct responses for MTF questions. We find that MTF questions reveal a high prevalence of …

Papers in Evolution

“When you have an established scientific emergent truth, it is true whether or not you believe in it.” Neil deGrasse Tyson, Science in America. Very few people outside of a particular scientific discipline can actually say they understand it, because most do not have the training to “speak the language.” They are then not particularly bothered by its tenets and predictions. Of all the major branches of science, however, evolutionary biology is an exception to this generalization because even though people are not versed in the field, they sometimes have a negative, knee-jerk objection. This objection is often because they …

Knowing What Students Know: How Question Formats Differ In Their Abilities To Reveal Student Thinking, Brian Couch

Discipline-Based Education Research Group Speaker Series

Instructors use assessment ubiquitously throughout undergraduate STEM courses to gauge student understanding of important concepts. The utility of an assessment can be partly judged by the degree to which it can detect the presence of correct and incorrect understandings. We will discuss a series of within-subjects controlled experiments to determine how student responses differ for questions posed in multiple-choice, multiple-true-false, or free-response formats as well as implications of this research for instructional practice.
