This paper presents an analysis of how affordances of ICT‐rich environments identified from a recent review of the research literature can support students in learning science in schools within a proposed framework for pedagogical practice in science education. Furthermore other pedagogical and curriculum innovations in science education (promoting cognitive change, formative assessment and lifelong learning) are examined to see how they may be supported and enhanced by affordances of ICT‐rich environments. The affordances that I have identified support learning through four main effects: promoting cognitive acceleration; enabling a wider range of experience so that students can relate science to their own and other real‐world experiences; increasing students' self‐management; and facilitating data collection and presentation. ICT‐rich environments already provide a range of affordances that have been shown to enable learning of science but integrating these affordances with other pedagogical innovations provides even greater potential for enhancement of students' learning. 相似文献

Model-based learning (MBL) has an established position within science education. It has been found to enhance conceptual understanding and provide a way for engaging students in authentic scientific activity. Despite ample research, few studies have examined the cognitive processes regarding learning scientific concepts within MBL. On the other hand, recent research within cognitive science has examined the learning of so-called relational categories. Relational categories are categories whose membership is determined on the basis of the common relational structure. In this theoretical paper, I argue that viewing models as relational categories provides a well-motivated cognitive basis for MBL. I discuss the different roles of models and modeling within MBL (using ready-made models, constructive modeling, and generative modeling) and discern the related cognitive aspects brought forward by the reinterpretation of models as relational categories. I will argue that relational knowledge is vital in learning novel models and in the transfer of learning. Moreover, relational knowledge underlies the coherent, hierarchical knowledge of experts. Lastly, I will examine how the format of external representations may affect the learning of models and the relevant relations. The nature of the learning mechanisms underlying students’ mental representations of models is an interesting open question to be examined. Furthermore, the ways in which the expert-like knowledge develops and how to best support it is in need of more research. The discussion and conceptualization of models as relational categories allows discerning students’ mental representations of models in terms of evolving relational structures in greater detail than previously done. 相似文献

To help students acquire mathematics and science knowledge and competencies, educators typically use multiple external representations (MERs). There has been considerable interest in examining ways to present, sequence, and combine MERs. One prominent approach is the concreteness fading sequence, which posits that instruction should start with concrete representations and progress stepwise to representations that are more idealized. Various researchers have suggested that concreteness fading is a broadly applicable instructional approach. In this theoretical paper, we conceptually analyze examples of concreteness fading in the domains of mathematics, physics, chemistry, and biology and discuss its generalizability. We frame the analysis by defining and describing MERs and their use in educational settings. Then, we draw from theories of analogical and relational reasoning to scrutinize the possible cognitive processes related to learning with MERs. Our analysis suggests that concreteness fading may not be as generalizable as has been suggested. Two main reasons for this are discussed: (1) the types of representations and the relations between them differ across different domains, and (2) the instructional goals between domains and subsequent roles of the representations vary.

Over the last years there has been a growing use of 3D virtual environments for educational purposes. Many studies advocate the integration of these environments in the daily teaching practice of various subjects. This requires innovative design in order create the appropriate affective/ pedagogical conditions as well as the development and use of well-structured activities in order to achieve effective collaborative learning. This paper presents an exploratory study in which collaborative learning strategies and cognitive apprenticeship models act as the pedagogical framework to facilitate learning and collaboration. The context is the teaching of mathematics in primary education via a 3D virtual environment. Specifically, we focus on evaluating students’ engagement (behavioral, affective and cognitive) in the collaborative learning process as they learn fractional concepts in a meaningful way. The findings show that a 3D virtual environment can support collaborative learning in primary school through its ability to enhance students’ engagement (behavioral, affective and cognitive) in the collaborative learning process. 相似文献

Multiple external representations (MERs) are central to the practice and learning of science, mathematics and engineering, as the phenomena and entities investigated and controlled in these domains are often not available for perception and action. MERs therefore play a twofold constitutive role in reasoning in these domains. Firstly, MERs stand in for the phenomena and entities that are imagined, and thus make possible scientific investigations. Secondly, related to the above, sensorimotor and imagination-based interactions with the MERs make possible focused cognitive operations involving these phenomena and entities, such as mental rotation and analogical transformations. These two constitutive roles suggest that acquiring expertise in science, mathematics and engineering requires developing the ability to transform and integrate the MERs in that field, in tandem with running operations in imagination on the phenomena and entities the MERs stand for. This core ability to integrate external and internal representations and operations on them – termed representational competence (RC) – is therefore critical to learning in science, mathematics and engineering. However, no general account of this core process is currently available. We argue that, given the above two constitutive roles played by MERs, a theoretical account of representational competence requires an explicit model of how the cognitive system interacts with external representations, and how imagination abilities develop through this process. At the applied level, this account is required to develop design guidelines for new media interventions for learning science and mathematics, particularly emerging ones that are based on embodied interactions. As a first step to developing such a theoretical account, we review the literature on learning with MERs, as well as acquiring RC, in chemistry, biology, physics, mathematics and engineering, from two perspectives. First, we focus on the important theoretical accounts and related empirical studies, and examine what is common about them. Second, we summarise the major trends in each discipline, and then bring together these trends. The results show that most models and empirical studies of RC are framed within the classical information processing approach, and do not take a constitutive view of external representations. To develop an account compatible with the constitutive view of external representations, we outline an interaction-based theoretical account of RC, extending recent advances in distributed and embodied cognition. 相似文献

Despite that BYOD (Bring Your Own Device) technology model has been increasingly adopted in education, few studies have been reported on how to integrate various apps on BYOD into inquiry-based pedagogical practices in primary schools. This article reports a case study, examining what apps on BYOD can help students enhance their science learning, and how students develop their science knowledge in a seamless inquiry-based learning environment supported by these apps. A variety of qualitative data were collected and analyzed. The findings show that the affordances of the apps on BYOD could help students improve their science knowledge without time and place constraints and gain a better sense of ownership in learning. 相似文献

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. 相似文献

Game-based learning supported by mobile intelligence technology has promoted the renewal of teaching and learning models. Herein, a model of Question-Observation-Doing-Explanation (QODE) based on smart phones was constructed and applied to science learning during school disruption in COVID-19 pandemic. In this study, from the theoretical perspective of cognitive-affective theory of learning with media, Bandura’s motivation theory and community of inquiry model, self-report measure was used to verify the effect of students’ scientific self-efficacy and cognitive anxiety on science engagement. A total of 357 valid questionnaires were used for structural equation model research. The results indicated that two types of scientific self-efficacy, as indicated by scientific learning ability and scientific learning behavior, were negatively associated with cognitive anxiety. In addition, cognitive anxiety was also negatively correlated to four types of science engagement, as indicated by cognitive engagement, emotional engagement, behavioral engagement, and social engagement through smartphone interactions. These findings provide further evidence for game-based learning promoted by smart phones, contributing to a deeper understanding of the associations between scientific self-efficacy, cognitive anxiety, and science engagement. This study points out that the QODE model is suitable for implementing smart mobile devices to students’ science learning.

Building on a pedagogical model designed to support the teaching and learning of the language of science investigation practices with middle school emergent bilingual learners, we developed a series of soccer and science investigations to promote interest and engagement in science learning. We used assemblage theory to study how students engaged in and acted within this bilingual curriculum situated in an afterschool soccer practice context. We found that soccer, a passion for several Latino students, can be used as a cultural tool for science teachers to support the emerging bilingual students’ learning process. Implications for educators and researchers considering ways of integrating diverse students’ cultural practices and passions with culturally sustaining pedagogies for science teaching and learning are discussed. 相似文献

With the affordances of mobile devices and experience-sampling method, this study took a person-in-context research orientation and examined the interactive relationship between self-efficacy, contextual features, and behavioral and cognitive engagement in authentic mobile learning contexts. Participants include 52 college students in teacher education programs. They responded to experience-sampling surveys based on the study events that they planned for the two weeks prior to exams during the semester. Regression analysis revealed that students’ course-specific self-efficacy and characteristics of planned study events were significantly associated with students’ behavioral engagement related to how well students implemented their study plans. Hierarchical regression analysis also showed that contextual features of the study environment, including study location and reasons for studying, moderated the relationship between task-specific self-efficacy and cognitive engagement. The results highlight the critical roles of self-efficacy and contextual features in influencing engagement in authentic anywhere and anytime mobile learning. The affordances and hinderances of experience-sampling method and mobile technologies in supporting engagement research were discussed. 相似文献

This position paper proposes the enhancement of teacher and student learning in science classrooms by tapping the enormous
potential of information communication and technologies (ICTs) as cognitive tools for engaging students in scientific inquiry.
This paper serves to challenge teacher-held assumptions about students learning science ‘from technology’ with a framework
and examples of students learning science ‘with technology’. Whereas a high percentage of students are finding their way in
using ICTs outside of school, for the most part they currently are not doing so inside of school in ways that they find meaningful
and relevant to their lives. Instead, the pedagogical approaches that are most often experienced are out-of-step with how
students use ICTs outside of schools and are not supportive of learning framed by constructivism. Here we describe a theoretical
and pedagogical foundation for better connecting the two worlds of students’ lives: life in school and life outside of school.
This position paper is in response to the changing landscape of students’ lives. The position is transformative in nature
because it proposes the use of cyber-enabled resources for cultivating and leveraging students new literacy skills by learning
‘with technology’ to enhance science learning. 相似文献

When learning with abstract and scientific multiple external representations (MERs), low prior knowledge learners are said to have difficulties in using these MERs to achieve conceptual understanding. Yet little is known about what these limitations precisely entail. In order to understand this, we presented 101 learners with low prior knowledge of abstract scientific MERs to see (a) how many, and what kind of ideas (propositions) learners remembered from these MERs and (b) what the impact of these ideas is on conceptual understanding of the content. Propositional analysis indicates that learners created flawed internal representations. The discussion analyses the potentials that the learners have in using abstract representations to increase their understanding of scientific information and possible effects of instruction. 相似文献

Teacher-researcher narrative accounts are essential and insightful for the science education field, yet they are few and far-between. In this forum, I engage in dialogue with Nicole Grimes’s auto-ethnographic narrative on the affordances her femme-Carribean identity allowed for some students to engage more deeply in science. While I agree with and applaud Grimes’s reflection on how her perceived social identity had positive effects on some students’ engagement in science, I trouble the notion of such a social identity being framed solely as an asset to student learning by examining the power dynamics inherent in the enacted nanny-child relationship. I also propose the need for deeper analyses on how a teacher’s social identity can impact students’ learning experiences in the science classroom by looking at how the boundaries of the science classroom are redefined and what additional resources are recruited that can foster deeper engagement. 相似文献

Despite a growing consensus regarding the value of inquiry-based learning (IBL) for students’ learning and engagement in the science classroom, the implementation of such practices continues to be a challenge. If science teachers are to use IBL to develop students’ inquiry practices and encourage them to think and act as scientists, a better understanding of factors that influence their attitudes towards scientific research and scientists’ practices is very much needed. Within this context there is a need to re-examine the science teachers’ views of scientists and the cultural factors that might have an impact on teachers’ views and pedagogical practices. A diverse group of Egyptian science teachers took part in a quantitative–qualitative study using a questionnaire and in-depth interviews to explore their views of scientists and scientific research, and to understand how they negotiated their views of scientists and scientific research in the classroom, and how these views informed their practices of using inquiry in the classroom. The findings highlighted how the teachers’ cultural beliefs and views of scientists and scientific research had constructed idiosyncratic pedagogical views and practices. The study suggested implications for further research and argued for teacher professional development based on partnerships with scientists. 相似文献

The Australian Government’s policy to transform higher education by 2020 includes plans to significantly raise the levels
of undergraduate enrolment by people of low socio-economic status. In light of this policy direction, this article examines
how a group of undergraduate students of low socio-economic status work to maintain their desire for learning and to remain
included in the university system despite experiencing cultural processes of exclusion. As the students reflect on the cultural
and pedagogical conditions that promote, support and enhance their participation and engagement in higher education, a picture
emerges of the importance of students’ relationships with academics. Whilst positive relationships help students to remain
engaged, negative experiences work against continuing participation and engagement. Given the desire of the Australian government
to increase participation in higher education by students from under-represented groups, this research identifies some challenges
and possibilities for both universities and academics. 相似文献

Genetics Reasoning with Multiple External Representations 总被引：1，自引：0，他引：1
This paper explores a case study of a class of Year 10 students (n=24) whose learning of genetics involved activities of BioLogica, a computer program that features multiple external representations (MERs). MERs can be verbal/textual, visual-graphical, or in other formats. Researchers claim that the functions of MERs in supporting student learning are to complement information or processes, to constrain the interpretation of abstract concepts, and to construct new viable conceptions. Over decades, research has shown that genetics remains linguistically and conceptually difficult for high school students. This case study using data from multiple sources enabled students' development of genetics reasoning to be interpreted from an epistemological perspective. Pretest-posttest comparison after six weeks showed that most of the students (n=20) had improved their genetics reasoning but only for easier reasoning types. Findings indicated that the MERs in BioLogica contributed to students' development of genetics reasoning by engendering their motivation and interest but only when students were mindful in their learning. Based on triangulation of data from multiple sources, MERs in BioLogica appeared to support learning largely by constraining students' interpretation of phenomena of genetics. 相似文献

In this article we describe our engagement in self-study as part of an examination of design-based research for education. We focus on graduate-level online teacher education as an example of how self-study provided a means of examining deeply our teaching and our roles as teacher and designer in the learning environment. We posit that online learning environments are particularly well suited for self-study to enhance design perspectives because the interactions between teacher and students are informed by personal context and mediated by technological tools. The graduate students in our courses were teacher leaders in literacy or mathematics who were learning how to support professional development for other teachers. Throughout our self-study research we found ourselves drawing upon our previous design research experiences, which aided our ability to engage in self-study: We were part of the classroom system, focusing on our roles within the teaching and learning process as designers of the online learning environment. Three key design principles resulted from our self-study process: focusing on systems of learning and teaching, designing pedagogical tools and products, and using iterative processes. Engaging in self-study enhanced our understanding and implementation of synchronous online instruction, particularly regarding our use of technological tools to enhance student learning and support learning communities. 相似文献

With the introduction of digital tools and online connectivity in primary schools, the shape of teaching and learning is shifting beyond the physical classroom. Drawing on the architecture of productive learning networks framework, we examine the affordances and limitations of an upper primary learning network and focus on how the digital and physical elements involved in set design shape teachers' pedagogical approaches and students' learning processes. The findings suggest that blended spaces support teachers' distributed orchestration of classroom activities across tools and resources while also leveraging students' engagement in reciprocal teaching and collaborative learning. 相似文献

There has been extensive research on children’s understanding of evaporation, but representational issues entailed in this understanding have not been investigated in depth. This study explored three students’ engagement with science concepts relating to evaporation through various representational modes, such as diagrams, verbal accounts, gestures, and captioned drawings. This engagement entailed students (a) clarifying their thinking through exploring representational resources; (b) developing understanding of what these representations signify; and (c) learning how to construct representational aspects of scientific explanation. The study involved a sequence of classroom lessons on evaporation and structured interviews with nine children, and found that a focus on representational challenges provided fresh insights into the conceptual task involved in learning science. The findings suggest that teacher‐mediated negotiation of representational issues as students construct different modal accounts can support enriched learning by enabling both (a) richer conceptual understanding by students; and (b) enhanced teacher insights into students’ thinking. 相似文献
