A cognitive approach to threshold concepts

This paper asks a fundamental question: what is happening inside the mind of the undergraduate during teaching and learning experiences, and how should curricula be designed to support it? A number of concepts lend themselves to providing an answer, principle among which is the relatively recent idea of Threshold Concepts. In this paper we attempt to critically evaluate both the ‘product’ and ‘process’ of Threshold Concepts and subject the idea to a stress test by comparing it to the longer established Schema Theory of Learning. This mapping enabled a novel empirical study involving undergraduate civil engineering students to be performed. The methods derived from Schema Theories of learning provide a set of findings that compliment and strengthen certain key areas of Threshold Concepts, as well as leading to the development of some interesting principles of curriculum design.     

Videobased lesson analysis: Effective science PD for teacher and student learning

The Science Teachers Learning from Lesson Analysis (STeLLA) project is a videobased analysis‐of‐practice PD program aimed at improving teacher and student learning at the upper elementary level. The PD program developed and utilized two “lenses,” a Science Content Storyline Lens and a Student Thinking Lens, to help teachers analyze science teaching and learning and to improve teaching practices in this year‐long program. Participants included 48 teachers (n = 32 experimental, n = 16 control) and 1,490 students. The STeLLA program significantly improved teachers' science content knowledge and their ability to analyze science teaching. Notably, the STeLLA teachers further increased their classroom use of science teaching strategies associated with both lenses while their students increased their science content knowledge. Multi‐level HLM analyses linked higher average gains in student learning with teachers' science content knowledge, teachers' pedagogical content knowledge about student thinking, and teaching practices aimed at improving the coherence of the science content storyline. This paper highlights the importance of the science content storyline in the STeLLA program and discusses its potential significance in science teaching and professional development more broadly. © 2011 Wiley Periodicals, Inc., J Res Sci Teach 48: 117–148, 2011     

Teaching physics to prospective elementary teachers: Bridging gaps or widening chasms

The education of prospective Elementary and Early Childhood (E&EC) teachers to teach science has been an on-going challenge for science teacher educators. Accordingly, a course in physical science was planned and implemented especially for prospective E&EC teachers. The purpose of this study was to understand the nature of the enacted curriculum and about the forces which constrained its evolution. Miller, the teacher of the course, had no prior experience in teaching prospective E&EC teachers and many of his experiences as a university level teacher were based on his teaching of physics majors. These experiences shaped his approach to teaching the course as did his years as a basketball coach. Miller was an expert in physics and constructed his role as teaching students significant scientific truths. Miller saw the purpose of the course as being to educate the students in science, not to prepare them to teach science. He was unwilling to address the goals of students that were oriented strongly toward becoming better teachers. The beliefs of the teacher constrained the enacted curriculum to an extent that gaps between the needs of students and the enacted curriculum were wider at the end of the course than they were at the beginning. Armstrong College In my opinion I think I failed completely, but I am quite happy with what I am trying to do. I just don't think I executed it well. So I was pretty unhappy with the whole experience in terms of the results, but I was not unhappy with the experience in terms of whether it was worth doing. I think it is important in science to develop free-thinking and being able to come to conclusions. Science is being able to reflect on the human condition, and being able to think about things you don't know about. (Miller)     

Space,relations, and the learning of science

In the literature on the situated and distributed nature of cognition, the coordination of spatial organization and the structure of human practices and relations is accepted as a fact. To date, science educators have yet to build on such research. Drawing on an ethnographic study of high school students during an internship in a scientific research laboratory, which we understand as a “perspicuous setting” and a “smart setting,” in which otherwise invisible dimensions of human practices become evident, we analyze the relationship between spatial configurations of the setting and the nature and temporal organization of knowing and learning in science. Our analyses show that spatial aspects of the laboratory projectively organize how participants act and can serve as resources to help the novices to participate in difficult and unfamiliar tasks. First, existing spatial relations projectively organize the language involving interns and lab members. In particular, spatial relations projectively organize where and when pedagogical language should happen; and there are specific discursive mechanisms that produce cohesion in language across different places in the laboratory. Second, the spatial arrangements projectively organize the temporal dimensions of action. These findings allow science educators to think explicitly about organizing “smart contexts” that help learners participate in and learn complex scientific laboratory practices.

Learning science in an era of globalization: a phenomenology of the foreign/strange

In this study, we propose a set of concepts for conceptualizing issues of learning science related to globalization, the encounter with the (radically) foreign/strange—as this occurs as part of migration and even as part of the encounter of a learner with the unknown content that science lessons are to impart—from the perspective of the experiencing person and the experience. We take an approach to the question of the foreign/strange that is grounded in philosophies of difference, which have emerged in continental Europe, and which make use of advances in phenomenology, dialectics, and materialism. We draw on ethnographic work in one undergraduate physics course at a Canadian university, where we followed in particular one female Japanese student, who had come to this country for the purpose of getting a degree. As an entry point and as source of empirical materials, we draw on our own auto/ethnographic experience that brings particular advantages to ally pathos to the experience of the foreign/strange, something is happening to (affecting) us that is beyond all experience, understanding, and anticipation. We articulate three phenomenological aspects that pathos (empathy) allows us to understand concerning the experience of the foreign/strange and then provide an exemplary and exemplifying analysis.
