Design and Design Thinking in STEM Education

Yeping Li, Alan H. Schoenfeld, Andrea A. diSessa, Arthur C. Graesser, więcej

Journal for STEM Education Research > 2019 > 2 > 2 > 93-104

Design and design thinking are vital to creativity and innovation, and have become increasingly important in the current movement of developing and implementing integrated STEM education. In this editorial, we build on existing research on design and design thinking, and discuss how students’ learning and design thinking can be developed through design activities in not only engineering and technology,...

On Thinking and STEM Education

Yeping Li, Alan H. Schoenfeld, Andrea A. diSessa, Arthur C. Graesser, więcej

Journal for STEM Education Research > 2019 > 2 > 1 > 1-13

The rapidly evolving and global field of STEM education has placed ever-increasing calls for interdisciplinary research and the development of new and deeper scholarship in and for STEM education. In this editorial, we focus on the topic of thinking, first with a brief overview of related studies and conceptions in the past. We then problematize a traditional conception of thinking in the context...

Radiation dose monitoring in pediatric fluoroscopy: comparison of fluoroscopy time and dose–area product thresholds for identifying high-exposure cases

Matthew S. Lazarus, Benjamin H. Taragin, William Malouf, Terry L. Levin, więcej

Pediatric Radiology > 2019 > 49 > 5 > 600-608

Background Fluoroscopy time has been used as a surrogate for radiation dose monitoring in pediatric fluoroscopy; however it does not account for factors such as magnification or collimation. Dose–area product (DAP) is a more accurate measure of radiation exposure but its dependence on patient weight and body-part thickness is a challenge in children of varying ages. Objective To determine whether...

On Classroom Observations

Alan H. Schoenfeld, Robert Floden, Fady Chidiac, Dennis Gillingham, więcej

Journal for STEM Education Research > 2018 > 1 > 1-2 > 34-59

As STEM education matures, the field will profit from tools that support teacher growth and that support rich instruction. A central design issue concerns domain specificity. Can generic classroom observation tools suffice, or will the field need tools tailored to STEM content and processes? If the latter, how much will specifics matter? This article begins by proposing desiderata for frameworks and...

Video analyses for research and professional development: the teaching for robust understanding (TRU) framework

Alan H. Schoenfeld

ZDM > 2018 > 50 > 3 > 491-506

This paper provides an overview of the teaching for robust understanding (TRU) Framework, its origins, and its evolving use. The core assertion underlying the TRU Framework is that there are five dimensions of activities along which a classroom must do well, if students are to emerge from that classroom being knowledgeable and resourceful disciplinary thinkers and problem solvers. The main focus of...

Uses of video in understanding and improving mathematical thinking and teaching

Alan H. Schoenfeld

Journal of Mathematics Teacher Education > 2017 > 20 > 5 > 415-432

This article characterizes my use of video as a tool for research, design and development. I argue that videos, while a potentially overwhelming source of data, provide the kind of large bandwidth that enables one to capture phenomena that one might otherwise miss; and that although the act of taping is in itself an act of selection, there is typically enough shown in a video that it rewards multiple...

Evaluating an Image Gently and Image Wisely Campaign in a Multihospital Health Care System

Kevin Fernandes, Terry L. Levin, Todd Miller, Alan H. Schoenfeld, więcej

Journal of the American College of Radiology > 2016 > 13 > 8 > 1010-1017

The efficacy of an Image Gently^®/Image Wisely^® radiology departmental campaign consisting of the optimization of CT protocols to reduce dose while maintaining quality, and an educational effort to alter the ordering patterns of referring physicians at a multihospital academic center, was evaluated.The numbers of CT, MR, and ultrasound studies performed at inpatient, outpatient, and emergency facilities...

How and Why Do Teachers Explain Things the Way They Do?

Alan H. Schoenfeld

Instructional Explanations in the Disciplines > Instructional Explanations in the Teaching and Learning of Mathematics > 83-106

Like jazz, teaching is both planned and improvisational. Many explanations come as planned parts of lessons, for example, when a teacher introduces a new topic and lays out its structure for students. But many also occur on the fly, in response to what students say, as the teacher realizes that what students say and do call for deeper, or different, understandings. One goal of this chapter is to address...

Reflections on Teacher Expertise

Alan H. Schoenfeld

Expertise in Mathematics Instruction > Cross-National Comparison and Reflections > 327-341

This chapter offers some broad reflections on issues of mathematics teacher expertise. The first main section stresses the importance of teachers’ and researchers’ beliefs and values – more generally, their conceptual models regarding “what counts” in the act of teaching. This raises the question of how one might frame explorations of teacher expertise in general, an issue I explore in the context...

Making sense of teaching

Alan H. Schoenfeld

ZDM > 2016 > 48 > 1-2 > 239-246

This article begins with a series of meta-level comments on the enterprise of observing and theorizing classroom teaching, using as a springboard a frequently discussed model from the literature. It then provides a series of commentaries on the empirical articles in this issue (volume 48, issue 1) of ZDM, with a main focus on methodological issues. It concludes with a brief return to the meta-level,...

On understanding and improving the teaching of university Mathematics

Alan H. Schoenfeld, Mike Thomas, Bill Barton

International Journal of STEM Education > 2016 > 3 > 1 > 1-17

Background This paper reports on a professional development workshop in University level mathematics. The workshop was grounded in Schoenfeld’s (How we think. A theory of goal-oriented decision-making and its educational applications, 2010) theoretical approach, emphasizing the roles of Resources (primarily, knowledge), Orientations (primarily, beliefs), and Goals (R / O ...

artykuł

Thoughts on scale

Alan H. Schoenfeld

ZDM > 2015 > 47 > 1 > 161-169

This essay reflects on the challenges of thinking about scale—of making sense of phenomena such as continuous professional development (CPD) at the system level, while holding on to detail at the finer grain size(s) of implementation. The stimuli for my reflections are three diverse studies of attempts at scale—an attempt to use ideas related to professional development in two different countries,...

Reflections on learning and cognition

Alan H. Schoenfeld

ZDM > 2014 > 46 > 3 > 497-503

The occasion of my 9th ICME—the first being in Berkeley in 1980, the most recent being in Seoul in 2012—provides an opportunity for reflecting on changes in the field over more than 30 years. “Learning and cognition” have a very different meaning now than they did in 1980. I argue that in various ways, the papers in this volume (derived from the ICME 12 Topic Study Group on Learning and Cognition)...

On forests, trees, elephants, and classrooms: a brief for the study of learning ecologies

Alan H. Schoenfeld

ZDM > 2013 > 45 > 3 > 491-495

The classroom intervention studies in this volume, ranging from the study of gestures to that of systemic implementation, are at very different grain sizes. A challenge is to see the forest for the trees – to see how these studies, focusing on different aspects of mathematical activity at different grain sizes, can be seen as aspects of a coherent whole. I propose an ecological metaphor for the study...

A US perspective on the implementation of inquiry-based learning in mathematics

Alan H. Schoenfeld, Jeremy Kilpatrick

ZDM > 2013 > 45 > 6 > 901-909

This paper discusses issues related to the potential adoption of inquiry-based learning (IBL) projects in mathematics in the United States. To explain the challenges faced in making a place for IBL in the mathematics curriculum, we describe the historical demands of working with a diverse, highly distributed educational system (that is, a system that does not have a central educational decision-making...

Classroom observations in theory and practice

Alan H. Schoenfeld

ZDM > 2013 > 45 > 4 > 607-621

This essay explores the dialectic between theorizing teachers’ decision-making and producing a workable, theoretically grounded scheme for classroom observations. One would think that a comprehensive theory of decision-making would provide the bases for a classroom observation scheme. It turns out, however, that, although the theoretical and practical enterprise are in many ways overlapping, the theoretical...

Problematizing the didactic triangle

Alan H. Schoenfeld

ZDM > 2012 > 44 > 5 > 587-599

This paper suggests that the typical framing of the didactic triangle in the English-speaking literature is narrower than it should be, and that it should be broadened to view classroom activities from a more social/cultural perspective. A framework for examining mathematically productive classrooms is given and exemplified, with the exemplification providing a point of departure for the kinds of...

Toward professional development for teachers grounded in a theory of decision making

Alan H. Schoenfeld

ZDM > 2011 > 43 > 4 > 457-469

There is now robust evidence that teachers’ and others’ in-the-moment decision making can be modeled and explained as a function of the following: their knowledge and other intellectual, social, and material resources; their goals; and their orientations (their beliefs, values, and preferences). The role of beliefs as they affect teachers’ behavior can thus be described at a level of mechanism—but...

Scatter radiation from chest radiographs: is there a risk to infants in a typical NICU?

Angela M. Trinh, Alan H. Schoenfeld, Terry L. Levin

Pediatric Radiology > 2010 > 40 > 5 > 704-707

Objective To evaluate the dose of scatter radiation to infants in a NICU in order to determine the minimal safe distance between isolettes. Materials and methods Dose secondary to scattered radiation from an acrylic phantom exposed to vertical and horizontal beam exposures at 56 kVp was measured at 93 cm and 125 cm from the center of the phantom. This corresponds to 2 and 3 ft between standard isolettes,...
