Students tend to think of their science courses as isolated and unrelated to each other, making it difficult for them to see connections across disciplines. In addition, many existing science assessments target rote memorization and algorithmic problem‐solving skills. Here, we describe the development, implementation, and evaluation of an activity aimed to help students integrate knowledge across introductory chemistry and biology courses. The activity design and evaluation of students' responses were guided by the

Abstract Framework for K‐12 Science Education as the understanding of core ideas and crosscutting concepts and the development of scientific practices are essential for students at all levels. In this activity, students are asked to use their understanding of noncovalent interactions to explain (a) why the boiling point differs for two pure substances (chemistry phenomenon) and (b) why temperature and base pair composition affects the stability of DNA (biological phenomenon). The activity was implemented at two different institutions (N = 441) in both introductory chemistry and biology courses. Students' overall performance suggests that they can provide sophisticated responses that incorporate their understanding of noncovalent interactions and energy to explain the chemistry phenomenon, but have difficulties integrating the same knowledge to explain the biological phenomenon. Our findings reinforce the notion that students should be provided with opportunities in the classroom to purposefully practice and support the use and integration of knowledge from multiple disciplines. Students' evaluations of the activity indicated that they found it to be interesting and helpful for making connections across disciplines. -
This NSF Grantees poster discusses an early phase Revolutionizing Engineering Departments (RED) project which is designed to address preparing engineering students to address large scale societal problems, the solutions of which integrate multiple disciplinary perspectives. These types of problems are often termed “convergent problems”. The idea of convergence captures how different domains of expertise contribute to solving a problem, but also the value of the network of connections between areas of knowledge that is built in undertaking such activities. While most existing efforts at convergence focus at the graduate and post-graduate levels, this project supports student development of capabilities to address convergent problems in an undergraduate disciplinary-based degree program in electrical and computer engineering. This poster discusses some of the challenges faced in implementing such learning including how to decouple engineering topics from societal concerns in ways that are relevant to undergraduate students yet retain aspects of convergence, negotiations between faculty on ways to balance discipline-specific skills with the breadth required for systemic understanding, and challenges in integrating relevant projects into courses with different faculty and instructional learning goals. One of the features of the project is that it builds on ideas from Communities of Transformation by basing activities on a coherent philosophical model that guides theories of change. The project has adopted Amartya Sen’s Development as Freedom or capabilities framework as the organizing philosophy. In this model the freedom for individuals to develop capabilities they value is viewed as both the means and end of development. The overarching goal of the project is then for students to build personalized frameworks based on their value systems which allow them to later address complex, convergent problems. Framework development by individual students is supported in the project through several activities: modifying grading practices to provide detailed feedback on skills that support convergence, eliciting self-narratives from students about their pathways through courses and projects with the goal of developing reflection, and carefully integrating educational software solutions that can reduce some aspects of faculty workload which is hypothesized to enable faculty to focus efforts on integrating convergent projects throughout the curriculum. The poster will present initial results on the interventions to the program including grading, software integration, projects, and narratives. The work presented will also cover an ethnographic study of faculty practices which serves as an early-stage baseline to calibrate longer-term changes.more » « less

Computational thinking is identified as one of the “essential skills for 21st-Century students.” [1] Studies of CT in school programs are being funded by many organizations, including the United States National Science Foundation. In this paper, we describe “lessons learned” over the first two years of a research program (PREDICTS: Principles and Resources for Educators to Infuse Computational Thinking in the Sciences) with the goal of developing knowledge of how to integrate CT into introductory high school biology and chemistry classes for all students. Using curricular modules developed by program staff, two in biology and two in chemistry, teachers piloting the program engaged students in CT with computational evidence from authentic tools in order to develop understanding of science concepts. Each module, representing about a week of instruction, addresses science ideas in the prescribed course of study for high school programs. Project researchers have collected survey data on teachers’: (1) beliefs about effective science teaching; (2) beliefs about their effectiveness as a science teacher and their students’ ability to learn science, and; (3) content preparedness. In addition, we observed module implementation, collected and analyzed student artifacts, and interviewed teachers at the conclusion of module implementation. Preliminary results indicated some challenges (access to technology, varying levels of experience among students) and cause for optimism (student and teacher engagement in CT and the computational tools used in the modules). Continuing research efforts are described in this paper, along with descriptions of the curricular modules and the use of observations and “CT check-ins” to assess student engagement in, application of, and learning of CT.more » « less

Abstract Background It is well established in the literature that active learning instruction in introductory STEM courses results in many desired student outcomes. Yet, regular use of high-quality active learning is not the norm in many STEM departments. Using results of a national survey, we identified 16 departments where multiple instructors reported using high levels of active learning in their introductory chemistry, mathematics, or physics courses. We conducted interviews with 27 instructors in these 16 departments to better understand the characteristics of such departments.
Results Using grounded theory methodology, we developed a model that highlights relevant characteristics of departments with high use of active learning instruction in their introductory courses. According to this model, there are four main, interconnected characteristics of such departments: motivated people, knowledge about active learning, opportunities, and cultures and structures that support active learning. These departments have one or more people who are motivated to promote the use of active learning. These motivated people have knowledge about active learning as well as access to opportunities to promote the use of active learning. Finally, these departments have cultures and structures that support the use of active learning. In these departments, there is a positive feedback loop that works iteratively over time, where motivated people shape cultures/structures and these cultures/structures in turn increase the number and level of commitment of the motivated people. A second positive feedback loop was found between the positive outcome of using active learning instruction and the strengthening of cultures/structures supportive of active learning.
Conclusions According to the model, there are two main take-away messages for those interested in promoting the use of active learning. The first is that all four components of the model are important. A weak or missing component may limit the desired outcome. The second is that desired outcomes are obtained and strengthened over time through two positive feedback loops. Thus, there is a temporal aspect to change. In all of the departments that were part of our study, the changes took at minimum several years to enact. While our model was developed using only high-use of active learning departments and future work is needed to develop the model into a full change theory, our results do suggest that change efforts may be made more effective by increasing the robustness of the four components and the connections between them.

Most chemistry educators agree that deep understanding of the nature of noncovalent interactions is essential for learning in chemistry. Yet decades of research have shown that students have persistent incorrect ideas about these interactions. We have worked in collaboration with a community of chemistry, biology, and biochemistry educators to develop a construct map to guide development of instructional and assessment resources related to the physical basis of noncovalent interactions in a biochemical context. This map was devised using data about student learning and expert perspectives on noncovalent interactions, resulting in a framework that provides a detailed roadmap for teaching and learning related to this essential concept. Here we describe the development of the construct map and our use of it to reform our biochemistry teaching practice. Because biochemistry relies on application of concepts learned in prerequisite courses, this construct map could be useful for wide range of courses including general chemistry, introductory biology, organic chemistry, and biochemistry.
