Afterschool interventions in STEM are linked to learning gains during the school day. These opportunities engage and excite students about STEM concepts since they observe a more hands-on, project-oriented approach. Often these opportunities for afterschool interventions are infrequent in nature and leave gaps for students in their maturation and understanding. Herein we describe the first report of an afterschool intervention, named NE STEM 4U, targeting socioeconomically disadvantaged middle school youth via a twice weekly, year-long intervention, studied across two years. We assessed the impact of this program on i.) short-term, individual student gains in STEM content knowledge and ii.) delivery …

Environmental Impact- Using Digital Media To Focus Student Learning, Crystal Randall, Sowmya Anjur, Donald Dosch

Faculty Publications & Research

Environmental issues are global challenges that our students will have to address in their future. Addressing these issues through curriculum helps bring purpose to students’ learning. We have developed a capstone project in our introductory biology class that allows students to engage in these issues in a creative and personalized manner, and which asks students to not only address the biology at the core of these issues but also suggest possible solutions to the problem. In this session, we will share how we scaffold our curriculum to prepare students for this experience, as well as show examples of student work.

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Career-planning courses are known to be effective career interventions for undergraduates, but their effect on developing alternate career plans was previously unknown. Forming alternate career plans increases the likelihood that students have viable career options available to them upon graduation because it encourages students to realistically consider multiple possibilities. Here we describe a one-term career-planning course developed in the context of an undergraduate biology curriculum. We assessed whether this course promoted development of primary and alternate career plans using a pre/post survey. We saw a significant increase in the percentage of students indicating they had plans aimed at achieving primary …

The Learning Loss Effect In Genetics: What Ideas Do Students Retain Or Lose After Instruction?, Amber Todd, William L. Romine Oct 2018

The Learning Loss Effect In Genetics: What Ideas Do Students Retain Or Lose After Instruction?, Amber Todd, William L. Romine

Biological Sciences Faculty Publications

Modern genetics is a relatively new domain, but it is increasingly important for students to have a firm grasp on the content, because genetic technologies are becoming more commonplace. In a previous study, we used the Learning Progression-based Assessment of Modern Genetics to assess high school students’ knowledge of genetics concepts after an intensive inquiry-based genetics instructional period. Given that this type of intensive inquiry-based instruction is unique, we are now investigating how students’ knowledge of genetics changes after instruction (i.e., learning loss effect). Using a six-measure longitudinal design, we found that students retained significant gains in five of the …

Yeast: The Gateway To Redefining And Improving Biology Labs, Connor Loomis

Biology Summer Fellows

Building off of collegiate research performed during the summer of 2018, this lesson plan outlines a lab for secondary students using yeast. Yeast is an affordable and convenient organism to introduce to secondary education, and students can learn a lot about biology through it. Essentially, the goal of the lab is for students to explore the effects of certain substances on the growth of yeast. While content is emphasized, this lesson plan also looks to build students’ understanding of science in general as well as proper laboratory skills and technique. In addition, it pushes students in their thinking as they …

Multiple–True–False Questions Reveal The Limits Of The Multiple–Choice Format For Detecting Students With Incomplete Understandings, Brian Couch, Joanna K. Hubbard, Chad Brassil Jun 2018

Multiple–True–False Questions Reveal The Limits Of The Multiple–Choice Format For Detecting Students With Incomplete Understandings, Brian Couch, Joanna K. Hubbard, Chad Brassil

School of Biological Sciences: Faculty Publications

By having students select one answer among several plausible options, multiple–choice (MC) questions capture a student’s preferred answer but provide little information regarding a student’s thinking on the remaining options. We conducted a crossover design experiment in which similar groups of introductory biology students were assigned verbatim questions in the MC format or multiple–true–false (MTF) format, which requires students to separately evaluate each option as either true or false. Our data reveal that nearly half of the students who select the correct MC answer likely hold incorrect understandings of the other options and that the selection rates for individual MC …

The human digestive system is a diverse network of cells, tissues, and organs that is regulated by intrinsic (e.g. nervous and endocrine systems) and extrinsic factors (e.g. secretions, pH, and the microbiome). Given the volume of content and the dense physiology involved, this system is difficult for instructors to teach and equally challenging for students to understand. This is especially true in our two-semester Human Anatomy and Physiology course for pre-health students at the University of Connecticut. In the Spring 2017 semester, we developed and implemented an active learning based approach when teaching the histology and regulation of gastric secretions …


The Effect Of Undergraduate Biology Research Experiences And Mentoring Structures On Student Self-Efficacy, Kyle Harris Apr 2018

The Effect Of Undergraduate Biology Research Experiences And Mentoring Structures On Student Self-Efficacy, Kyle Harris

Doctoral Dissertations and Projects

Collaborative inquiry within undergraduate research experiences (UREs) is an effective curriculum tool to support student growth. This study seeks to understand how collaborative inquiry within undergraduate biology student experiences are affected within faculty mentored experiences and non-mentored experiences at a large private southeastern university. Undergraduate biology students engaged in UREs (faculty as mentor and non-mentor experiences) were examined for statistically significant differences in student self-efficacy. Self-efficacy was measured in three subcomponents (thinking and working like a scientist, scientific self-efficacy, and scientific identity) from student responses obtained in an online survey. Responses were analyzed using a nonparametric equivalent of a t …

Eileen Hebets Publications

Increased integration and synergy between formal and informal learning environments is proposed to provide multiple benefits to science learners. In an effort to better bridge these two learning contexts, we developed an educational model that employs the charismatic nature of arachnids to engage the public of all ages in science learning; learning that aligns with the Next Generation Science Standards (NGSS Disciplinary Core Ideas associated with Biodiversity and Evolution). We created, implemented, and evaluated a family-focused, interactive science event—Eight-Legged Encounters (ELE)—which encompasses more than twenty modular activities. Volunteers facilitated participant involvement at each activity station and original …

This Teacher- Researcher Partnership Program facilitated opportunities in inquiry, science content, interaction with laboratory instrumentation and technologies, critical discussion of literature, and dissemination of findings for participating in-service science teacher professional development utilizing an inquiry-based theoretical framework wherein we examined science teacher preparation via inquiry-based methods in …


Many Paths Toward Discovery: A Module For Teaching How Science Works, Rebecca M. Price, Kathryn E. Perez Jan 2018

Many Paths Toward Discovery: A Module For Teaching How Science Works, Rebecca M. Price, Kathryn E. Perez

Biology Faculty Publications and Presentations

Improving students' understanding of how science works requires explicit instruction. Here, we test the efficacy of a module based on two previously published activities (the "Cube Puzzle" and the case study "Asteroids and Dinosaurs") that teach how science works to college science majors. Students also use the How Science Works Flowchart from Understanding Science (http://undsci.berkeley. edu/) to reflect on these activities. To assess the efficacy of this module, we asked students to illustrate the process of science before and after the intervention. After the intervention, students' diagrams were significantly more complex and nonlinear. Students also incorporated more social aspects of …
