Title: Epistemic Design for STEM Education
Abstract:
Epistemic design is the design of learning environments that promote growth in students’ epistemic competence...
A theory of epistemic design theory includes both (a) a normative model of epistemic competence and (b) an instructional theory of how to promote this competence through effective design. In this talk, I will present an overview of a theory of epistemic design that I have been developing in collaboration with my colleagues (including Ravit Golan Duncan, Sarit Barzilai, Ron Rinehart, Ala Samarapungavan, Luke Buckland, William Pluta, and Gale Sinatra). Much of this research has been situated in the context of middle-school life science classes focused on model-based inquiry. I will discuss implications of our work in middle-school classes for a theory of epistemic design, including potential extensions to STEM education at the college level.
I will begin by discussing the goals of epistemic design, and then turn to the issue of what design features can achieve these goals. The theoretical framework that guides our theory of epistemic design theory is the AIR model of epistemic cognition, which views epistemic cognition as comprising Aims, Ideals (or standards), and Reliable Processes for achieving epistemic aims. I will discuss the AIR framework and explain how we have used it in epistemic design, using data from our research project to support critical design recommendations.

Title: Modeling Expert Ways of Explaining and Reasoning with Concepts and Representations of Biomolecular Processes and their Mechanisms
Abstract:
In the molecular and microscopic world of biomolecular science, instructors use a great diversity of, often confusing, concepts and representations to explain cellular structures and processes....
A well-structured explanation of cellular processes coordinates reasoning about the mechanisms with visual, symbolic, and data representations. Since students have problems both understanding biomolecular mechanisms depicted by representations and how to competently explain them, we decided to simultaneously address both types of difficulties through a hybrid model composing a combination of the key elements of two different established expert models, the Methods-Analogies-Context-How (MACH) and Concept-Reasoning-Mode of representation (CRM) models. The MACH model represents the key components of biology expert explanations of mechanisms, while the CRM model depicts the factors affecting a person’s ability to interpret representations. In this presentation, in collaboration with Nancy Pelaez and Kamali Sripathi, I will demonstrate how this hybrid model can be used as a guiding framework for the design of instruction about the mechanism of oxidative phosphorylation in a biochemistry class. I will also demonstrate with qualitative data how the hybrid model can be used to identify and code for various elements of instructor explanations and ways of reasoning. A future goal is to use the hybrid model to inform the design of student activities and assessments aimed at developing expert-like explanatory and reasoning skills to do with biomolecular processes and their mechanisms.

Title: Scientific Modeling Approaches and Findings Across a Spectrum of Learning in Science Education
Abstract:
Scientific modeling is a critical practice for advancing science and engineering as well as helping people make sense of the world....
By scientific modeling, I refer to a practice of embodying ideas of how and why a system works or a phenomenon occurs into a model, testing and evaluating the model, and revising the model to explain and predict the world. Yet engaging learners in scientific modeling can be challenging for a number of reasons, and the outcomes of larger scale implementations of various forms of model-based instruction is not always well-understood. This talk will share approaches and findings from scientific modeling research in which I have engaged over the past twenty year. The context of that research ranges from elementary school modeling of the hydrological cycle, to upper elementary and middle school work on the particle nature of matter and force and motion, to introductory college-level biology. In particular, I will highlight (a) the nature of scientific modeling in these contexts, (b) research findings and outcomes of engaging learners in modeling, (c) indicators of productive designs and support for learners and their instructors, and (d) implications for modeling across the spectrum of learning.

Title: Mental and Physical Models on the Frontiers of Science
Abstract:
What are the cognitive and material practices that drive innovation on the frontiers of science? What kinds of mental and physical representations are central to the practices of interdisciplinary research laboratories?
These were the two research questions that informed our four year ethnographic studies of two university bioengineering research laboratories—a tissue engineering and a neuroengineering lab. While the work and objectives for these labs were in no way related, we found similarities in their modeling practices and in their efforts to bridge the in vivo/in vitro divide. This talk will focus on two in vitro model systems, one from each lab, that were central to their work, with a particular emphasis on the coordination and integration of biological and engineering models needed to design, fabricate and use these devices. I will end with implications for education.

Title: Student Authorship and Computational Tools in K-12 Models-Based Education
Abstract:
In this presentation, I will describe and share data from two ongoing projects that each seek to introduce young students to the practice of scientific modeling by building on familiar expressive activities like sketching and flipbook animation.
SiMSAM and DataSketch invite middle school students to create, revise, and test their own scientific models - expressed as computational simulations or data visualizations - using their own sketches and animations as starting points. We are exploring how such tools (1) allow youth the representational flexibility needed for them to truly engage as *authors* of scientific models, while also (2) structuring those ideas so that students' models can be compared and contrasted with one another, and with conventional scientific models. I will describe the technological, material, and social supports we have found that make complex, computationally-mediated modeling possible in the middle school classroom. I will also briefly describe some emerging theoretical and practical implications of this work for teacher education and theories of learning in modeling-rich classrooms.

Title: End-to-End Modeling and Model-Based Reasoning in STEM
Abstract:
We want to support authentic scientific practices in STEM education...
We also want to support learning about the processes of scientific modeling in addition to domain knowledge. To these ends, I will present an interactive technology that seeks to support end-to-end modeling and model-based reasoning. I will describe how this technology evolves from more than a decade of research on modeling and model-based reasoning in STEM education, including (1) Structure-Behavior-Function (SBF) models of complex systems, (2) different types of causal explanations within SBF conceptual models, (3) use of SBF conceptual models to support learning about ecological systems, (4) integration of conceptual and simulation modeling, (5) metacognitive tutoring for learning about the processes of scientific modeling, (6) automatic spawning of simulations from conceptual models, and (7) integration with big data to support end-to-end modeling and model-based reasoning.

Title: Characterizing Modeling and Simulation Practices in Science and Engineering Education
Abstract:
Advances in modeling and simulation have major implications in discovery and innovation by supporting advances in healthcare, energy, economic competitiveness, and national security...
Thus, equipping future scientists and engineers with modeling and simulation skillset is essential to boost the chances for engineering discovery and innovation success. This agenda proposes a design-based research approach to investigate under what conditions modeling and simulation practices can effectively be integrated with disciplinary courses in undergraduate engineering education.
We have explored two different approaches for modeling and simulation in engineering education: a programming approach and a configuring approach. Our preliminary findings suggest that in a programming approach, students encounter significant challenges mapping from conceptual to mathematical representations and from mathematical to algorithmic representations. In a configuring approach, students struggle with the complexity of the graphical user interface. However, once students overcome respective challenges, they seemed to benefit from the produced visualizations. In a second study we further explored the impact of a learning design that implements principles of Cognitive Apprenticeship Model to support different stages of the modeling and simulation process following a programming approach. Our preliminary findings suggest that this framework can be an appropriate support to help students develop modeling and simulation adaptive expertise.
