Developing the ability to recontextualise cellular respiration: an explorative study in recontextualising biological concepts

In many science education practices, students are expected to develop an understanding of scientific knowledge without being allowed a view of the practices and cultures that have developed and use this knowledge. Therefore, students should be allowed to develop scientific concepts in relation to the contexts in which those concepts are used. Since many concepts are used in a variety of contexts, students need to be able to recontextualise and transfer their understanding of a concept from one context to another. This study aims to develop a learning and teaching strategy for recontextualising cellular respiration. This article focuses on students’ ability to recontextualise cellular respiration. The strategy allowed students to develop their understanding of cellular respiration by exploring its use and meaning in different contexts. A pre- and post-test design was used to test students’ understanding of cellular respiration. The results indicate that while students did develop an acceptable understanding of cellular respiration, they still had difficulty with recontextualising the concept to other contexts. Possible explanations for this ack of understanding are students’ familiarity with the biological object of focus in a context, the manner in which this object is used in a context and students’ understanding of specific elements of cellular respiration during the lessons. Although students did develop an adequate understanding of the concept, they do need more opportunities to practice recontextualising the concept in different contexts. Further research should focus on improving the strategy presented here and developing strategies for other core concepts in science.     

Professional development for design-based learning in engineering education: a case study

Design-based learning (DBL) is an educational approach in which students gather and apply theoretical knowledge to solve design problems. In this study, we examined how critical DBL dimensions (project characteristics, design elements, the teacher's role, assessment, and social context) are applied by teachers in the redesign of DBL projects. We conducted an intervention for the professional development of the DBL teachers in the Mechanical Engineering and the Electrical Engineering departments. We used the Experiential Learning Cycle as an educational model for the professionalisation programme. The findings show that the programme encouraged teachers to apply the DBL theoretical framework. However, there are some limitations with regard to specific project characteristics. Further research into supporting teachers to develop open-ended and multidisciplinary activities in the projects that support learning is recommended.     

The conceptual change approach to improving teaching and learning: An evaluation of a Hong Kong staff development programme

This paper reports a study ofthe effectiveness of an innovative approach tostaff development, the conceptual changeapproach, which attempts to change teachers'frameworks for conceptualising teaching andlearning. The evaluation investigated theprogramme at three levels: the impact on theconceptions of teaching of the participants,the resultant impact on teaching practices, andthe consequential effect on student learning.Encouraging results were obtained. Theprogramme brought about detectable conceptualchange or conceptual development in two-thirdsof the sample group. Subsequently, all the`changed' teachers received better ratings ontheir teaching practices from their students inthe following academic year while none of thosewho did not change their conceptions showedsimilar gains in student rating scores. Aresultant positive impact on their students'studying approaches was observed for half ofthe teachers who changed their conceptions.     

Conceptual knowledge in talk and text: What does it take to understand a science question?

What is referred to as conceptual knowledge is one of the mostimportant deliverables of modern schooling. Following the dominance of cognitive paradigmsin psychological research, conceptual knowledge is generally construed assomething that lies behind or under performance in concrete social activities. In the presentstudy, students' responses to questions, supposedly tapping conceptual knowledge,have been studied as parts of concrete communicative practices. Our focus has been onthe differences between talk and text. The most frequent approach for generatinginsight into conceptual knowledge is by means of written tests. However, the very mannerin which people handle the demands of this particular form of mediation is seldomattended to. This problem has been studied by means of two items taken from theinternational comparison of knowledge and achievement in mathematics and science, TIMSS.The results reveal that it is highly doubtful if the items test knowledge of scienceconcepts to any significant extent. In both instances, the difficulties students have, asrevealed in the interview setting, seem to be grounded in problems in understanding somedetails in the written questions. These difficulties are generally easily resolved in aninteractive setting. It is argued that the low performance on these items can to a largeextent be accounted for by the abstract and highly demanding form of communication that iswritten language.     

Prior knowledge moderates instructional effects on conceptual understanding of statistics

This study investigated the effects of different teaching and learning methods for statistics for 2 levels of prior knowledge on cognitive load, propositional knowledge, and conceptual understanding. Teaching methods were whether or not to provide students with propositional information, and learning strategies were self-explaining the learning material and explaining in pairs. The results indicate that prior knowledge facilitates propositional knowledge development and leads to differential effects of teaching and learning methods on conceptual understanding: Only low prior knowledge students profit from additional information in the learning task and/or explaining in pairs. An implication of these findings is that low prior knowledge students should be guided into the subject matter by means of working in pairs on learning tasks that comprise additional information. Once students have developed more knowledge of the subject matter, they should be stimulated to work individually on learning tasks that do not comprise additional information.     

概念同化、改变和迁移在教学中的应用

学习是对现有知识结构的丰富和重构。丰富是现有知识对新知识的同化过程,重构则是概念改变,表现为理论的修正和改变。上述学习理论运用于教学中的一个重要方面就是设计和组织学习材料。学习材料具有多种形式,包含着与学习者固着观念相联系的同化点,能引发学习者的认知冲突,或显示新知识的特性导致概念改变,并且能提供新的情景便于学习者的知识迁移。因此综合设计和组织学习材料是促进学习者对知识进行有意义建构,提高其学习能力的关键。

Action research in initial teacher education: an explorative study

The aim of the study was to describe students’ and teacher educators’ practical experience with action research and to identify a number of special points for consideration (opportunities and limitations) which could play a role in putting research into practice in concrete terms in the courses. Students and teacher educators on three Dutch initial teacher education programmes which treat action research as both a means of professional development and a necessary professional qualification were involved. These were programmes for specific teaching levels and subjects in Dutch schools. Four special points for consideration are identified: action research and the educational core qualifications of the profession; difference between action research by student teachers during their initial education and experienced teachers in their own workplace; students’ mixed experiences and perceptions of research; and embedded research‐based activities in the programme. The authors conclude that action research should be considered from different perspectives: as a professional approach, a body of skills that is needed to make the connection between knowing that and knowing why; and as a way of improving practice by systematically building up practice‐based knowledge.

Learning in physics by doing laboratory work: towards a new conceptual framework

Drawing on a study that explores university students’ experiences of doing laboratory work in physics, this article outlines a proposed conceptual framework for extending the exploration of the gendered experience of learning. In this framework situated cognition and post‐structural gender theory are merged together. By drawing on data that aim at exploring the gendered experience of learning in physics in the laboratory setting, a case is made for the proposed conceptual framework to facilitate an analysis of gender as an active process that relates the dynamics of this process to the emerging physicist identities of the students. In other words, this framework allows for an analysis of the gendered learning experiences in a context such as physics education that goes well beyond the usual ‘women‐friendly’ teaching approaches.     

Figures of speech in the physics classroom: a process of conceptual change

Background: This study investigates the role of figures of speech in the process of conceptual change in the physics classroom. Purpose: Its objectives are to examine what teachers and students perceive to be the advantages in using figures of speech in teaching physics concepts, what they perceive to be the challenges in using them, and how teachers use these in their classrooms to minimize the challenges faced. Sample We chose a purposive sample of 95 students and nine teachers of physics, in four schools in Lebanon. Design and methods: A mixed-method approach was used. Interviews were conducted with physics teachers; questionnaires were distributed to students, and non-participant classroom observations were carried out. Results: Teachers viewed figures of speech as a tool that helps them transmit abstract physics concepts to students in a simpler and concrete way. Questionnaires and non-participant observations revealed several examples of figures of speech used and the positive responses of students towards them. Conclusions: The study suggests several ways to overcome the drawbacks. This study highlights the urgent need for all stakeholders to work collaboratively to include figures of speech in the curriculum to enhance the process of conceptual change in the physics classroom.     

Towards an Understanding of Situated Learning:Students' Perceptions in an Interpretation Course

Situated learning approach has been applied in various teaching contexts, and increasing advocations have been shown in the particular context of language teaching. This study applied situated learning appoach in the interpretation course of college English major students and is designed to gain the students' perception of stuated learning. From the study, it is found that most of the students showed their positive attitudes towards situated learning approach applied in their interpretation course and enjoyed their learning in such learning enviroment. However, there is still a long way to go to achieve their satisfaction. Teachers need to explore more for creating authentic atmosphere in the interpretation course to arise students' interest and passion to a greater degree.

Comparing balance and inverse methods on learning conceptual and procedural knowledge in equation solving: a cognitive load perspective

We examined the use of balance and inverse methods in equation solving. The main difference between the balance and inverse methods lies in the operational line (e.g. +2 on both sides vs ?2 becomes +2). Differential element interactivity favours the inverse method because the interaction between elements occurs on both sides of the equation for the balance method but only on one side of the equation for the inverse method. In an experimental study, 63 students (mean age = 13) were randomly allocated to either balance or inverse group to undertake a pre-test, study an instruction sheet, complete acquisition equations, sit for a post-test and a concept test. Procedural knowledge was assessed on performance on practice equations and post-test, whereas conceptual knowledge was assessed on performance on the concept test. The inverse group outperformed the balance group on practice equations but not the post-test. Both the balance and inverse groups scored higher on the inverse concept test than the balance concept test. Positive association between performance on procedural knowledge and performance on conceptual knowledge was found for the inverse group but not the balance group. Overall, the evidence obtained indicates a number of educational implications for implementation.     

Priming institutional change through effective project management:A case study of the Chic project

This paper explores how learning and teaching innovations undertaken by externally funded projects, with a fixed remit and lifecycle, can be integrated successfully into institutional educational developments. The example and methods of one particular project, in embedding its work within and relating it to the context of wider, nationally-promoted educational designs, is utilized to illustrate the possibilities for fostering institutional change. Such change relies upon working to promote a climate whose norms support a culture of trust, where team-working can forge a broader ownership of innovation     

The Effect of Verbal and Visuo-Spatial Abilities on the Development of Knowledge of the Earth

Difficulties in students’ understanding of the spherical model of the Earth have been shown in previous studies. One of the reasons for these difficulties lies in beliefs and preliminary knowledge that hinder the interpretation of the scientific knowledge, the other reason may lie in the low level of verbal and visuo-spatial abilities. The study aims to investigate the effect of verbal and visuo-spatial abilities, but also that of preliminary knowledge on the later development of the knowledge of the Earth in school. 176 schoolchildren (96 boys and 80 girls) from five schools were tested; the mean age of the children during the first interview was seven years and eight months. All students were interviewed twice – in grades 1 and 2, before and after they had learnt the topic in school. Factual, scientific and synthetic knowledge was assessed. The facilitative effect of visuo-spatial and verbal abilities and preliminary factual and scientific knowledge on students’ knowledge of astronomy after having learnt the topic in school was shown. In contrast, the hindering effect of synthetic knowledge was not found.     

Professional development design considerations in climate change education: teacher enactment and student learning

Climate change is one of the most pressing challenges facing society, and climate change educational models are emerging in response. This study investigates the implementation and enactment of a climate change professional development (PD) model for science educators and its impact on student learning. Using an intrinsic case study methodology, we focused analytic attention on how one teacher made particular pedagogical and content decisions, and the implications for student’s conceptual learning. Using anthropological theories of conceptual travel, we traced salient ideas through instructional delivery and into student reasoning. Analysis showed that students gained an increased understanding of the enhanced greenhouse effect and the implications of human activity on this enhanced effect at statistically significant levels and with moderate effect sizes. However, students demonstrated a limited, though non-significant gain on the likely effects of climate change. Student reasoning on the tangible actions to deal with these problems also remained underdeveloped, reflecting omissions in both PD and teacher enactment. We discuss implications for the emerging field of climate change education.     

Encouraging the development of higher-level study skills using an experiential learning framework

Teachers have only recently considered how study skills support in higher education (HE) can be delivered in a way that encourages experiential learning. This paper aims to substantiate, or otherwise, the idea that a carefully developed initiative can encourage the experiential learning of study skills. In addition, it considers whether such an approach might also allow student access to some of the higher-level study skills required for successful university study. Focus group data were used to evaluate a module delivered to sports students at a post-1992 university in the UK. This data suggested that the module facilitated learning in each stage of Kolb's experiential learning cycle. Moreover, there was evidence that the module encouraged students to undertake an ‘epistemological shift’ in which they moved from seeing knowledge as a set of uncontested facts to seeing it as something that they are expected to question and contribute to themselves.     

Misconception of sound and conceptual change: A cross‐sectional study on students' materialistic thinking of sound

There is a concern that materialistic thinking—meaning the tendency to attribute a set of matter‐like properties to nonmatter concepts—is one of the central barriers that students face in the journey toward understanding scientific concepts. The cross‐sectional study presented here used the Sound Concept Inventory Instrument (SCII) (Eshach, [ 2014 ], Physical Review Physics Education Research, 10, 010202) to examine how Taiwanese students (N = 717: Grade 7 to undergraduate level) associate the nonmaterial concept of sound with this set of (erroneous) materialistic properties and/or with the (correct) scientific view. Its results show that students in all academic level groups associated sound, at least to some extent, with all of the materialistic properties defined in the instrument. Grades 7–9 evidenced the greatest amount of materialistic thinking, followed by Grade 11, with the lowest levels of materialistic thinking being shown by Grades 10 and 12, as well as university students. We also found that the respondents' confidence in the materialistic view they expressed was high. The results suggest that the extent to which students associate sound with materialistic thinking is not ordered by academic level, but was rather influenced by the immediate relevance of each group's recent curriculum to the topic of sound. This article concludes by examining the results through the lens of several different theories of conceptual change, and by making suggestions, in light of these results, for how the teaching of sound concepts might be improved.
