The Role of Threshold Concepts in an Interdisciplinary Curriculum: a Case Study in Neuroscience

Threshold concepts have been widely utilized to understand learning in academic disciplines and student experiences in a disciplinary curriculum. This study considered how threshold concepts might operate within an interdisciplinary setting. Data were collected through interviews with 40 doctoral students enrolled in an interdisciplinary program as well as content analysis of interdisciplinary curricula. The findings emphasize the importance of the integrative process to interdisciplinary initiatives. Interdisciplinary threshold concepts do not result from the addition of multiple disciplines, but rather are fostered through unique facets of the interdisciplinary experience.     

A Conceptual Analysis of Evolutionary Theory for Teacher Education

In this paper we present a schematic overview of the central concepts in evolutionary theory, setting them off against the background of widespread misconceptions about them. Our aim is to provide high school teachers with (1) an overview of those particular concepts that they can expect students to have difficulties with, (2) a comparison of students’ alternative conceptions with the corresponding accepted scientific concepts and (3) some recommendations for teaching these concepts. We aim to improve the learning and teaching of evolution by making the relevant conceptual debates within the fields of history and philosophy of science more accessible to science teachers. We intended this conceptual analysis to be of use as a teaching tool for in-service teachers, as well as biology teachers in training.     

Conceptualizations of nature: An interpretive study of 16 ninth graders' everyday thinking

The research reported in this article sought to provide a broader understanding of high school science students as persons by describing the personal thoughts, or everyday thinking, about a question relevant to science: What is Nature? The purpose was to gain an understanding of students' fundamental beliefs about the world on the basis that developing scientific literacy can be successful only to the extent that science finds a niche in the cognitive and cultural milieu of students. The theoretical background for this research came from cultural anthropology and the methodology was interpretive, involving student interviews. The assertions of the study in summary form were: (a) The ninth‐grade students in the study tended to discuss Nature using several different perspectives (e.g., religious, aesthetic, scientific, conservationist). A rich breadth of perspectives typically characterized any one student's discussion of Nature. (b) After 9 years of schooling, however, the level of science integration within everyday thinking remained low for many of these ninth graders. In their discussions of Nature, most volunteered little school knowledge of science. They were aware of school science topics such as the ozone layer, rain forests, and the Big Bang theory. Such topics were voluntarily mentioned but usually without elaboration even when asked. (c) Science grade success was not correlated with the concepts these ninth graders typically chose to use in a discussion about the natural world. The students with the most grade success in science had not necessarily grasped fundamental concepts about Nature and science. (d) Regardless of school grade success, including school science grade success, most of the ninth graders attached considerable importance to personal experiences with Nature. Their environmental inclinations were strong. The article ends with a discussion of the implications. © 1999 John Wiley & Sons, Inc. J Res Sci Teach 36: 541–564, 1999     

The Vibrating Universe: Astronomy for the Deaf

The Deaf have often been overlooked when designing informal STEM education and public outreach activities. Astronomers at UC Riverside and teachers at the California School for the Deaf, Riverside (CSDR), have designed an astronomy workshop aimed specifically for the Deaf using the school’s on-site sound lab. We have used astronomy for this workshop because the field has a significant edge over other sciences to act as portal for K-12 engagement in science given the imagery it presents, the answers it offers to grand questions, and its interdisciplinary nature. The workshop is an unconventional activity that excites the students and provides a positive experience in astronomy, based on knowledge that they already acquired beforehand in the classroom. Our workshop uses electromagnetic emissions, enhanced sounds and sonification processes of cosmic phenomena that have low frequencies and sufficiently distinguishable patterns which are delivered to students through a specialized designed sound lab for the Deaf. Storytelling paired with videos and images are used to give understandable meaning to the sounds of the Universe. Positive feedback was collected from over 80 students who participated in our workshop. Our activity can be reproduced elsewhere to further engage the Deaf community in science.

     

Physics and Art – A Cultural Symbiosis in Physics Education

This paper presents and discusses examples of works of art which, if included in science curricula, could prompt an understanding by students of some concepts in optics through a discussion of the context in which they were created. Such discussion would elucidate the meaning of the artworks and, at the same time, challenge students’ misconceptions, attracting their attention to the scientific aspects of the art works concerned. This type of learning represents a culturally rich approach to modern science curricula. The simplified contrasting of science and humanities is criticized.     

Erratum to: Relating Narrative, Inquiry, and Inscriptions: Supporting Consequential Play

In this paper we describe our research using a multi-user virtual environment, Quest Atlantis, to embed fourth grade students in an aquatic habitat simulation. Specifically targeted towards engaging students in a rich inquiry investigation, we layered a socio-scientific narrative and an interactive rule set into a multi-user virtual environment gaming engine to establish a virtual world through which students learned about science inquiry, water quality concepts, and the challenges in balancing scientific and socio-economic factors. Overall, students were clearly engaged, participated in rich scientific discourse, submitted quality work, and learned science content. Further, through participation in this narrative, students developed a rich perceptual, conceptual, and ethical understanding of science. This study suggests that multi-user virtual worlds can be effectively leveraged to support academic content learning.

FORM AND STRUCTURE OF CHINESE CHARACTERS AND CHILDREN��S UNDERSTANDING OF SCIENCE

The written representation in Chinese can be considered as a pictorial or a symbolic representation which is very different from English where the pronunciation is related to how the word is spelt. Students face challenges of a very different nature when science is learnt in Chinese compared with English. In Hong Kong, students are making translations between the language they use in their daily lives, the science concepts and the scientific terms. The research team designed an interview protocol for primary school pupils in order to identify the pupils’ alternative concepts of science and if these alternative concepts are related to the structure of the Chinese language. The findings suggest that there are alternative conceptions related to (a) the form of the Chinese character—for example, the Chinese character for crocodile includes a radical meaning fish, and so pupils may take it that a crocodile is a fish; (b) the meaning of the Chinese character—for example, an electronic buzzer is a device used to attract bees as in Chinese, the character contains the word meaning “bees producing sound”. The findings provide important data for future endeavours aiming to compare the learning of science using different languages and on ways in which primary teachers may better facilitate their pupils in learning science.     

Youth science expertise,environmental identity,and agency in climate action filmmaking

Abstract

The Green Ninja Film Academy (GENIE) is an interdisciplinary curriculum development project that examines the efficacy of combining climate science concepts and practices with digital storytelling for middle school youth. We present findings from iterative enactments of this design-based research project in 2017 (N?=?296) and 2018 (N?=?539). On average, youth increased scores on assessments of science content and practices while demonstrating competencies in filmmaking and science explanations. Further, an inverse correlation was seen between initial identification with the environment and change in environmental identification throughout the unit. Results suggest that integration of creative filmmaking into a climate science curriculum aligned to the Next Generation Science Standards can increase engagement and science proficiency particularly for youth who initially show less engagement in environmental science.     

The language of science and preferential thinking styles: A comparison between hindi speaking students (in India) and english speaking students (in Tasmania)

A study of science textbooks and students' responses indicates that many key concepts are treated at different levels of meaning. As a consequence of these observations we have attempted to examine what we have termed students' “preferential thinking style.” To do this, the level of meaning that students preferred when thinking about each of 16 key concept definitions associated with the theme, the nature of matter, was measured for each concept. The same concept definitions had already been studied in respect to students' ability to recognize them. Each of the 16 concept terms was formulated at the three levels of meaning defined by us as: membership, partial association, and generalization. The resulting test of preferential thinking style was administered to representative samples of Hindi-speaking high school students in India (826) and English-speaking high school students in Tasmania (1635). Some marked changes in the relative development of preferential thinking styles for the two groups were observed which raises questions associated with the importance of this notion as an outcome of science teaching.     

Catalysing student autonomy through action research in a problem centred learning environment

This autobiographical article describes action research, utilising a hermeneutic dialectic methodology, on the efficacy of problem-based learning. In the emergent research design, the research focus for the teacher evolved as: “Can I, as an instructor, teach science in such a way that: the use of science in real life is emphasised; an interdisciplinary approach is utilised; assessment is an integral part of instruction; and learning is student-driven, not teacher directed?” To answer this research question, the article focuses on the emergence of students' critical thinking skills, the relevance of science concepts taught, the interdisciplinary nature of the problems addressed, the use of alternative methods of assessment, and the changing roles of the teacher and the students. One significant finding reported in the article is the development of student autonomy, as the problem-based learning format allowed students freedom to pursure diverse research agendas and to accept increasing responsibility for their own learning.     

Context-based learning in the middle years: achieving resonance between the real-world field and environmental science concepts

ABSTRACT

There is growing interest in how to engage middle school students in science to improve their enthusiasm for science and to arrest the decline in uptake in the senior years. Also, there is interest in improving students’ application of science to real-life situations, a requirement for international tests. One approach that offers hope for improving students’ connections between concepts and context is the context-based approach. Context-based units that connect canonical science with the real-world of the student’s local community have been trialled in the senior years but are new in the middle years. Research in senior classes has shown that students who were taught through a context-based approach demonstrated fluid transitions between the context and concepts in written work and student-student conversations. In the current ethnographic study we built on our previous work and investigated how students make connections between the environmental science concepts and the context of the weekly visits to the local creek. Students were immersed in the real-world context by completing an 11-week environmental science unit that required assessment of the health of a creek. Two assertions emerged; firstly, student-student conversations at the creek afforded students the opportunity for interconnections between environmental science concepts and the context (defined as resonance); and secondly, students’ written reports about the health of the creek demonstrated resonance. Furthermore, group work encouraged students the agency to complete sets of tasks that privileged visually obvious environmental science concepts such as pollution, identification of plants/animals or turbidity/flow rate.     

Reading for meaning: The foundational knowledge every teacher of science should have

Reading is fundamental to science and not an adjunct to its practice. In other words, understanding the meaning of the various forms of written discourse employed in the creation, discussion, and communication of scientific knowledge is inherent to how science works. The language used in science, however, sets up a barrier, that in order to be overcome requires all students to have a clear understanding of the features of the multimodal informational texts employed in science and the strategies they can use to decode the scientific concepts communicated in informational texts. We argue that all teachers of science must develop a functional understanding of reading comprehension as part of their professional knowledge and skill. After describing our rationale for including knowledge about reading as a professional knowledge base every teacher of science should have, we outline the knowledge about language teachers must develop, the knowledge about the challenges that reading comprehension of science texts poses for students, and the knowledge about instructional strategies science teachers should know to support their students’ reading comprehension of science texts. Implications regarding the essential role that knowledge about reading should play in the preparation of science teachers are also discussed here.     

Teaching the basic relationships between sentences

Research and classroom experience (Bormuth et al., 1970; Nichols, 1980) support the idea that middle and secondary students often have difficulty understanding relationships within and between sentences. Knowledge gleaned from discourse analysis concepts can assist teachers in providing useful instructional strategies to help students comprehend progressively larger units of meaning. We want to encourage teachers to try some of the instructional strategies we have provided and also to experiment with additional ideas drawn from the information presented here. We hope other teachers will further explore this potentially rich area of comprehension instruction.     

The student with a thousand faces: from the ethics in video games to becoming a citizen

Video games, as technological and cultural artifacts of considerable influence in the contemporary society, play an important role in the construction of identities, just as other artifacts (e.g., books, newspapers, television) played for a long time. In this paper, we discuss this role by considering video games under two concepts, othering and technopoly, and focus on how these concepts demand that we deepen our understanding of the ethics of video games. We address here how the construction of identities within video games involves othering process, that is, processes through which, when signifying and identifying ??Ourselves??, we create and marginalize ??Others??. Moreover, we discuss how video games can play an important role in the legitimation of the technopoly, understood as a totalitarian regime related to science, technology and their place in our societies. Under these two concepts, understanding the ethics of video games goes beyond the controversy about their violence. The main focus of discussion should lie in how the ethics of video games is related to their part in the formation of the players?? citizenship. Examining several examples of electronic games, we consider how video games provide a rich experience in which the player has the opportunity to develop a practical wisdom (phronesis), which can lead her to be a virtuous being. However, they can be also harmful to the moral experiences of the subjects when they show unethical contents related to othering processes that are not so clearly and openly condemned as violence, as in the cases of sexism, racism or xenophobia. Rather than leading us to conclude that video games needed to be banned or censored, this argument makes us highlight their role in the (science) education of critical, socially responsible, ethical, and politically active citizens, precisely because they encompass othering processes and science, technology, and society relationships.     

From Words to Concepts: Focusing on Word Knowledge When Teaching for Conceptual Understanding Within an Inquiry-Based Science Setting

This qualitative video study explores how two elementary school teachers taught for conceptual understanding throughout different phases of science inquiry. The teachers implemented teaching materials with a focus on learning science key concepts through the development of word knowledge. A framework for word knowledge was applied to examine the students’ level of word knowledge manifested in their talk. In this framework, highly developed knowledge of a word is conceptual knowledge. This includes understanding how the word is situated within a network of other words and ideas. The results suggest that students’ level of word knowledge develops toward conceptual knowledge when the students are required to apply the key concepts in their talk throughout all phases of inquiry. When the students become familiar with the key concepts through the initial inquiry activities, the students use the concepts as tools for furthering their conceptual understanding when they discuss their ideas and findings. However, conceptual understanding is not promoted when teachers do the talking for the students, rephrasing their responses into the correct answer or neglecting to address the students’ everyday perceptions of scientific phenomena.     

Students' Meaning‐making of Socio‐scientific Issues in Computer Mediated Settings: Exploring learning through interaction trajectories

This article reports on a study concerning secondary school students’ meaning‐making of socio‐scientific issues in Information and Communication Technology‐mediated settings. Our theoretical argument has as its point of departure the analytical distinction between ‘doing science’ and ‘doing school,’ as two different forms of classroom activity. In the study we conducted an analysis of students working with web‐based groupware systems concerned with genetics. The analysis identified how the students oriented their accounts of scientific concepts and how they attempted to understand the socio‐scientific task in different ways. Their orientations were directed towards finding scientific explanations, towards exploring the ethical and social consequences, and towards ‘fact‐finding.’ The students’ different orientations seemed to contribute to an ambivalent tension, which, on the one hand, was productive because it urged them into ongoing discussions and explicit meaning‐making. On the other hand, however, the tension elucidated how complex and challenging collaborative learning situations can be. Our findings suggest that in order to obtain a deeper understanding of students’ meaning‐making of socio‐scientific issues in Information and Communication Technology‐mediated settings, it is important not only to address how students perform the activity of ‘doing science.’ It is equally important to be sensitive with respect to how students orient their talk and activity towards more or less explicit values, demands, and expectations embedded in the educational setting. In other words, how students perform the activity of ‘doing school.’     

Using Technology-Enhanced Inquiry-Based Instruction to Foster the Development of Elementary Students’ Views on the Nature of Science

The Next Generation Science Standards support understanding of the nature of science as it is practiced and experienced in the real world through interconnected concepts to be imbedded within scientific practices and crosscutting concepts. This study explored how fourth and fifth grade elementary students’ views of nature of science change when they engage in a technology-enhanced, scientific inquiry-oriented curriculum that takes place across formal and informal settings. Results suggest that student engagement in technology-enhanced inquiry activities that occur in informal and formal settings when supported through explicit instruction focused on metacognitive and social knowledge construction can improve elementary students’ understanding of nature of science.
