Teaching Energy Concepts by Working on Themes of Cultural and Environmental Value

Energy is a central topic in physics and a key concept for understanding the physical, biological and technological worlds. It is a complex topic with multiple connections with different areas of science and with social, environmental and philosophical issues. In this paper we discuss some aspects of the teaching and learning of the energy concept, and report results of research on this issue. To immerse science teaching into the context of scientific culture and of the students’ cultural world, we propose to select specific driving issues that promote motivation for the construction of science concepts and models. We describe the design and evaluation of a teaching learning path developed around the issue of greenhouse effect and global warming. The experimentation with high school students has shown that the approach based on driving issues promotes students’ engagement toward a deeper understanding of the topic and favours further insight. The evolution of students’ answers indicates a progressively more correct and appropriate use of the concepts of heat, radiation, temperature, internal energy, a distinction between thermal equilibrium and stationary non equilibrium conditions, and a better understanding of greenhouse effect. Based on the results of the experimentation and in collaboration with the teachers involved, new materials for the students have been prepared and a new cycle of implementation, evaluation and refinement has been activated with a larger group of teachers and students. This type of systematic and long term collaboration with teachers can help to fill the gap between the science education research and the actual school practice.     

Learning Through Constructing Representations in Science: A framework of representational construction affordances

Compared with research on the role of student engagement with expert representations in learning science, investigation of the use and theoretical justification of student-generated representations to learn science is less common. In this paper, we present a framework that aims to integrate three perspectives to explain how and why representational construction supports learning in science. The first or semiotic perspective focuses on student use of particular features of symbolic and material tools to make meanings in science. The second or epistemic perspective focuses on how this representational construction relates to the broader picture of knowledge-building practices of inquiry in this disciplinary field, and the third or epistemological perspective focuses on how and what students can know through engaging in the challenge of representing causal accounts through these semiotic tools. We argue that each perspective entails productive constraints on students’ meaning-making as they construct and interpret their own representations. Our framework seeks to take into account the interplay of diverse cultural and cognitive resources students use in these meaning-making processes. We outline the basis for this framework before illustrating its explanatory value through a sequence of lessons on the topic of evaporation.

Simulating scientific thinking online: an example of research‐led teaching

In the contemporary higher education system there is growing interest in, and debate about, the need to strengthen and sustain the relationships between teaching and research. While there are multiple and varied explanations about these relationships, most acknowledge the importance of designing learning activities that explicitly develop the research–teaching nexus: a methodology known as research‐led teaching. The paper illustrates the integration of a research‐led teaching approach in an online context, using an ocean (climate) model simulation activity in two undergraduate units as a case study. The modelling activity draws on disciplinary research as the underpinning content and stimulus for learning, and incorporates tasks designed to simulate scientific thinking as well as facilitate understanding of abstract concepts about the ocean (and atmosphere) climate system. It also demonstrates a research‐led teaching activity that has been successfully applied in different disciplinary contexts, physical geography (atmospheric science sub‐discipline) and physics.     

Some features of causal reasoning: common sense and physics teaching

The idea of causality is central in science and has long given rise to debate among philosophers and scientists. While the tendency to avoid causality seems to have become dominant in science and philosophy, research in science education has shown the strong presence in common reasoning of causal explanations, often conceived as a ‘mechanism’ capable of accounting for physical transformations. Some researchers have proposed using this common causal reasoning as a basis for teaching–learning sequences, especially in electricity and mechanics. This paper analyses some features of causal reasoning used in physics by students, using questionnaires and interviews involving students and teachers. This study has shown three aspects which are related to one another: a confusion between efficient and contingent causes, between the conditions of occurrence of a phenomenon and the cause actually producing it; a tendency to ‘displace’ causes, skipping intermediate objects; and a difficulty in connecting local causes and global effects. The paper highlights the differences between common reasoning and scientific usage, and their effect on learning. In fact, these trends of reasoning must be taken into account in teaching: they should be considered not only as creating an obstacle to learning physics, but also as resources at the learner’s disposal.     

学生的科学探究能力:国外的研究及启示

当前的科学课程改革对学生的科学探究能力提出了要求,这是我国的科学教育研究者和广大教师面临的一个新课题。西方发达国家在20世纪下半叶的科学课程改革中就开始进行有关的研究和实践,有三种主要的教学和研究模型及实践结果可供我们借鉴。这些研究结果表明,科学探究能力是一种具有复杂结构的高层次能力,对科学探究能力的培养不能简单化和程式化。我们应当在借鉴有关研究成果的基础上,把握科学探究的本质特征,采用复杂性科学的研究方法,建立适当的教学和研究模型,从理论和实践两方面开展深入研究。

Invented Science: A Framework for Discussing a Persistent Problem of Practice

A central goal of science education reform is for students to participate in scientific sense making rather than to merely acquire science facts. However, even in classrooms utilizing reform-based pedagogies, students are typically allowed to construct knowledge only insofar as they construct expected knowledge. In this report and reflection, we use activity theory to demonstrate how this pervasive tension between learning correct ideas and constructing one’s own ideas often results in unacknowledged slippage between competing activity systems within reform efforts. We use an analogy to the domain of spelling to introduce invented science—a framework for describing the activity of science learning that reduces this slippage by giving knowledge construction true priority over the canon. We describe the origins and purposes of invented spelling to theorize the nature of learning in invented science. We conclude by articulating the theoretical and practical implications of this analogy for science teaching and learning.     

Teaching science or cultivating values? Conservation NGOs and environmental education in Costa Rica

A key ongoing debate in environmental education practice and its research relates to the content and goals of environmental education programmes. Specifically, there is a long history of debate between advocates of educational perspectives that emphasise the teaching of science concepts and those that seek to more actively link environmental and social issues. In practice, educators and organisations respond to these tensions in a variety of ways, often strongly reflecting the particular social and economic contexts in which they are located. Much of the research in the area, however, has tended to take a narrow focus on either purely theoretical concerns or on individual programmes in schools or protected areas. In contrast, this research used an ethnographic approach to explore debates about the content and aims of educational programmes between diverse educational actors in one community in Costa Rica. The research revealed that environmental education: (i) is an important local site for the active contestation of understandings of the natural world and humans’ relationships to it; and (ii) can be part of wider struggles over the control of processes of local development and environmental management. The study further suggests that while theoretical discussion about the relative merits of diverse approaches to environmental teaching and learning is important, if that analysis is not situated within a particular social, economic and political context, it is likely to reveal relatively little about how or why particular perspectives on environmental education may dominate or remain marginal in a specific place.     

Design‐based Research: Case of a teaching sequence on mechanics

Design‐based research, and particularly its theoretical status, is a subject of debate in the science education community. In the first part of this paper, a theoretical framework drawn up to develop design‐based research will be presented. This framework is mainly based on epistemological analysis of physics modelling, learning and teaching hypotheses. It includes grand theories, a specific theory that following Cobb, Confrey, diSessa, Lehrer, and Schauble is a “humble theory” in the sense that it does “real work”, and tools for design. In the second part, we will show how this specific theory and its tools led designers to develop teaching resources in the case of a teaching sequence on mechanics (Grade 10). We will explain how the components of the specific theory and tools guide the design at different levels; the conceptual structure of the teaching sequence, the chronology of the activities, the various choices of the type of activity and their wording. This presentation makes the bases of designing teaching resources explicit and therefore allows for scientific debate.     

现代远程教育考试应是过程而非环节——一种考试改革的理论与行动框架

Exploring the Development of Pre-Service Science Elementary Teachers’ Pedagogical Content Knowledge

This paper explores how a group of pre-service elementary science student teachers came to understand the development of their Pedagogical Content Knowledge (PCK) over the course of a semester??s study in a science methods course. At the start of the semester, PCK was introduced to them as an academic construct and as a conceptual tool that they could use to plan for, and assess, the development of their professional knowledge and practice as beginning science teachers. All participants were provided with a tool known as a CoRe (Content Representation) and the manner in which they worked with the CoRe was such that it supported them in planning for and assessing their own learning about teaching elementary science through a focus on the development of their PCK. Through analysis of data derived from the application of a CoRe based methodology (modified and adapted for this study) to the teaching of the science topic of Air, participants?? reasons for, confidence in, and perceived meaningfulness of their learning about science teaching could be examined. In so doing, the nature of participants?? PCK development over time was made explicit. The results illustrate real possibilities for ways of enhancing student teachers?? ongoing professional learning in teacher preparation and offer a window into how the nature of PCK in pre-service education might be better understood and developed.     

Analysing design and technology as an educational construct: an investigation into its curriculum position and pedagogical identity

The hierarchal status of academic disciplines, what defines valuable or legitimate knowledge and what should we teach our children is a topic of much debate. Amidst concerns of an academic decline, tackling the culture of low expectation and anti-intellectualism, the need to address social justice, and its by-product of cultural reproduction, is the focus of current education policy. Set within the UK, this paper presents a critical review of the literature relating to disciplinary knowledge and teaching and learning regimes, specifically seeking to explore the subcultures which exist between design and technology and its associated curricula counterparts that combine to produce science, technology, engineering and mathematics (STEM). The purpose being to proffer an explanation that is supportive in developing an understanding as to why design and technology is perceived by many to be of less value than its STEM counterparts. Situation within a functionalist approach to STEM education policy, findings are discussed in relation to design and technology, which as a subject is caught between the identities of academic and vocational exponents, and it is from this perspective that complex nature and perceived value of design and technology is explored.     

Developing a Fine-Grained Learning Progression Framework for Carbon-Transforming Processes

Science educators have called for using the learning progression approach to align curriculum, instruction, and assessment. In line with this trend, we conducted both assessments and teaching experiments with students from grades 4 to 12 (717 students participated in the pre-assessments and 682 students participated in the post-assessments). The goal of the study is to develop a learning progression framework that provides effective guidance for curriculum and instruction on carbon-transforming processes in socio-ecological systems. We conducted the study in three research cycles. We developed a matter-and-energy learning progression framework during the first two cycles. This learning progression framework was used to guide the teaching intervention in the third research cycle. Clinical interviews and written assessments were implemented before and after the teaching intervention. In the process of data analysis, we found that the matter-and-energy learning progression framework did not provide a fine-grained depiction of students' reasoning. Therefore, we developed the five-practice learning progression framework, and used it to re-analyze data. Results indicate that the teaching intervention has helped students to achieve significant learning gains, but it was not effective enough in helping students achieve the upper anchor of the learning progression framework—constructing sophisticated scientific explanations. The results also indicate that students tended to rely on coherent and consistent reasoning to construct explanations. Based on the findings, we provide instructional suggestions and discuss the implications for climate change education and learning progression research.     

Learning science by doing science: an authentic science process-learning model in postsecondary education

Research on understanding the full extent that an authentic science research experience engages students in how scientists think and act is sparse. ‘Learning-science-by-doing-science’ (LSDS) is an emerging self-guided process-learning model in postsecondary science education. It offers authentic science research opportunities that drive students to think and act like scientists. This study investigates the LSDS approach as a potential model for science learning at postsecondary level and aims to answer a main research inquiry – what are the students’ and teaching staff’s perceptions of students’ learning gains and the quality of their learning experiences in an authentic research environment within the LSDS model? To answer this question, data were collected from the students, alumni, instructors, teaching assistants and the program director via questionnaires, focus groups and interviews. Students’ and staff’s lived experiences and their perceptions on their authentic research experiences within the LSDS model were used to articulate the key attributes and stages of the LSDS model. The outcomes of this study can be used to help other science programs implement similar authentic research process learning approaches in their own contexts.     

Professional Identity Development of Teacher Candidates Participating in an Informal Science Education Internship: A focus on drawings as evidence

This study investigated the professional identity development of teacher candidates participating in an informal afterschool science internship in a formal science teacher preparation programme. We used a qualitative research methodology. Data were collected from the teacher candidates, their informal internship mentors, and the researchers. The data were analysed through an identity development theoretical framework, informed by participants’ mental models of science teaching and learning. We learned that the experience in an afterschool informal internship encouraged the teacher candidates to see themselves, and to be seen by others, as enacting key recommendations by science education standards documents, including exhibiting: positive attitudes, sensitivity to diversity, and increasing confidence in facilitating hands‐on science participation, inquiry, and collaborative work. Our study provided evidence that the infusion of an informal science education internship in a formal science teacher education programme influenced positively participants’ professional identity development as science teachers.     

The Pendulum as Presented in School Science Textbooks of Greece and Cyprus

When we refer to scientific knowledge, we, implicitly or explicitly, refer to its three components, namely its conceptual framework, its methodological principles and its cultural aspects. The pendulum is a topic of science teaching and learning where all three of these aspects can be examined with the aim of gaining a holistic appreciation of the transformation of a natural phenomenon into a phenomenon of the physical sciences and how this can then be recontextualized into a topic of school science learning. The main objective of this study is to examine whether this richness of the pendulum as a topic of teaching is revealed in the school science textbooks in Greece and Cyprus, for both primary and secondary education. We will use an analytical mapping instrument in order to determine, whether the pendulum is introduced at some grade level and, if so, in what context. We will then use an interpretive instrument, which relies on taxonomy of science curricula into traditional, innovative and constructivist programs, in order to attach meaning to the analysis. Finally, we will formulate a series of proposals in relation to the educational value of the simple pendulum at the Greek and Cypriot gymnasium level.     

Constructing genealogies of teachers' emotions in science teaching

This article reports on a three‐year ethnographic study with an experienced elementary science teacher and describes the role of her positive and negative emotions in constructing her science pedagogy, curriculum planning, and relationships with children and colleagues. Examples are offered of the different emotional experiences she related to her science teaching, and it is shown how insights from this research are useful and significant to researchers and educators who want to improve science teaching and learning. A conceptual and methodological framework developed by the author that is based on an interdisciplinary approach in researching emotions is presented. Finally, some implications of researching emotions for elementary science teacher education and science education reform are suggested. © 2002 John Wiley & Sons, Inc.

A Philosophically Informed Teaching Proposal on the Topic of Energy for Students Aged 11�C14

Learning about energy is recognized as an important objective of science teaching starting from the elementary school. This creates the need for teaching simplifications that compromise the abstract nature of this concept with students?? need for a satisfactory qualitative definition. Conventional teaching approaches have failed to respond to this need in a productive manner. In an attempt to maintain consistency with how energy is understood in physics, they tend to either provide abstract definitions or bypass the question what is energy?, which is vitally important to students. In this paper, we describe the epistemological barriers that are inherent in conventional attempts to introduce energy as a physical quantity and we suggest that shifting the discussion to a philosophically-oriented context could provide a means to address them in a productive manner. We propose a teaching approach, for students in the age range 11?C14, that introduces energy as an entity in a theoretical framework that is invented and gradually elaborated in an attempt to analyze the behavior of diverse physical systems, and especially the various changes they undergo, using a coherent perspective. This theoretical framework provides an epistemologically appropriate context that lends meaning to energy and its various features (i.e. transfer, form conversion, conservation and degradation). We argue that this philosophically informed teaching transformation provides a possible means to overcome the various shortcomings that typically characterize attempts to introduce and elaborate the construct of energy while at the same time it allows integrating, in a meaningful and coherent manner, learning objectives relevant to the understanding of the Nature of Science (NOS), which is recognized as a valuable component of learning in science. In this paper, we outline the rationale underlying this teaching approach and describe a proposed activity sequence that illustrates our proposal.     

Operationalizing and Detecting Disengagement Within Online Science Microworlds

In recent years, there has been increased interest in engagement during learning. This is of particular interest in the science, technology, engineering, and mathematics domains, in which many students struggle and where the United States needs skilled workers. This article lays out some issues important for framing research on this topic and provides a review of some existing work with similar goals on engagement in science learning. Specifically, here we seek to help better concretize engagement, a fuzzy construct, by operationalizing and detecting (i.e., identifying using a computational method) disengaged behaviors that are antithetical to engagement. We, in turn, describe our real-time detector (i.e., machine learned model) of disengaged behavior and how it was developed. Last, we address our ongoing research on how our detector of disengaged behavior will be used to intervene in real time to better support students' science inquiry learning in Inq-ITS (Inquiry-Intelligent Tutoring System; Gobert, Sao Pedro, Baker, Toto, & Montalvo, 2012; Gobert, Sao Pedro, Raziuddin, & Baker, 2013).
