This article reports on the collaboration of six states to study how simulation‐based science assessments can become transformative components of multi‐level, balanced state science assessment systems. The project studied the psychometric quality, feasibility, and utility of simulation‐based science assessments designed to serve formative purposes during a unit and to provide summative evidence of end‐of‐unit proficiencies. The frameworks of evidence‐centered assessment design and model‐based learning shaped the specifications for the assessments. The simulations provided the three most common forms of accommodations in state testing programs: audio recording of text, screen magnification, and support for extended time. The SimScientists program at WestEd developed simulation‐based, curriculum‐embedded, and unit benchmark assessments for two middle school topics, Ecosystems and Force & Motion. These were field‐tested in three states. Data included student characteristics, responses to the assessments, cognitive labs, classroom observations, and teacher surveys and interviews. UCLA CRESST conducted an evaluation of the implementation. Feasibility and utility were examined in classroom observations, teacher surveys and interviews, and by the six‐state Design Panel. Technical quality data included AAAS reviews of the items' alignment with standards and quality of the science, cognitive labs, and assessment data. Student data were analyzed using multidimensional Item Response Theory (IRT) methods. IRT analyses demonstrated the high psychometric quality (reliability and validity) of the assessments and their discrimination between content knowledge and inquiry practices. Students performed better on the interactive, simulation‐based assessments than on the static, conventional items in the posttest. Importantly, gaps between performance of the general population and English language learners and students with disabilities were considerably smaller on the simulation‐based assessments than on the posttests. The Design Panel participated in development of two models for integrating science simulations into a balanced state science assessment system. © 2012 Wiley Periodicals, Inc.

This paper presents a methodology for characterizing computer-based learning environments, focusing on the cognitive, pedagogical, and interactive features. The framework for this characterization is explained in relation to the relevant theories and findings in cognitive and instructional research. The methodology is illustrated by a characterization of computer-based learning environments developed by student teachers and professionals. The usability of these environments is analyzed along the dimensions of the framework presented. The results showed that this methodology can systematically and precisely characterize the cognitive, pedagogical, and interactive features of computer-based learning environments. It can be used to predict and explain the success or failure that a given software program promotes for learning particular types of knowledge. The applications of this methodology for the evaluation and design of computer-based learning environments, for instructional research in various instructional contexts, as well as for the study of expertise in the development of computer-based learning environments, are discussed.  相似文献

A brief overview overview is provided of how the scaffolding metaphor has been defined in educational contexts. This includes a discussion of what theories guide decision-making regarding what to scaffold as well as considerations as to whom or what does the scaffolding (human teachers, peers and tutors or computer tutors or support tools designed for learning environments). The scaffolding construct intersects instruction and assessment in that instructors assess learners to determine what type or level of scaffold is sufficient to help learners reach their potential. Such assessments are dynamic and ongoing and can occur through dialogue and social interactions with or without the use of technology. Hence scaffolds are provided when and where necessary but they are also removed when evidence of learning exists. This article describes how the contributors to this issue have extended the scaffolding metaphor to open-ended technology based environments. Empirical studies are reviewed with regard to how they extend the scaffolding metaphor in terms of the theories that guide the design of scaffolds, the metrics designed to assess how scaffolding affects learning and in terms of teaching scaffolding techniques to others.  相似文献

The paper explores the relationship between formative assessment and social software. Formative assessment practices though beneficial for student learning become marginalised and constrained in open and distance learning environments in higher education. Feedback is a key factor in formative assessment and learners can benefit from the deployment of emerging technologies and the opportunities for participation and dialogue afforded by social software. This paper explores and proposes a conceptual framework for this relationship. The claim is that the social dimensions of emerging technologies – specifically, blogs and wikis – allow for formative assessment practices to be re‐invented or at the very least facilitated by essentially participative and student‐focussed interventions. A comparison of these technologies against formative assessment mechanisms identifies the types of processes that these new tools might best support to encourage effective feedback approaches that both empower the learner and enhance their learning experience.  相似文献

Enthusiasts for new social software do not always acknowledge that belonging to e‐learning communities depends upon complex and often unresolved identity issues for learners. Drawing on the author’s previous research on belonging in social learning, the paper presents a theory of identity congruence in social learning and brings to the foreground the importance of identities which arise from expressions of gender, class, ethnicity, age, etc. in the social, operational and, in particular, the knowledge‐building aspects of learning. These three dimensions of identity congruence are used to evaluate the potential of new social software. While social software might encourage some learners to engage in social and operational identity work, there are disadvantages for others, and learner‐generated knowledge and e‐assessment practices can be divisive. Inclusive e‐learning depends upon pedagogies and assessments which enable learners to shift and transform identities, and not solely on widening the range of technologies available. Such caution should underpin future research.  相似文献

Open educational resources (OERs) are increasingly adopted in non-formal education contexts. However, little research has been conducted to investigate the self-directed learning patterns of non-formal learners using OERs. A lack of knowledge about non-formal learners precludes discussions on how to support their self-regulated learning in open learning environments. We explored the self-directed learning patterns of 1892 non-formal online learners who were using OER repositories. In addition, we examined whether differences existed in future intentions to use OERs between learners with different learning patterns. Four latent classes were identified, and learners’ age was found to affect class membership. We also found that non-formal learners’ use of self-directed learning strategies predicted their future intentions to use OERs. This study advanced our understanding of the subpopulations of non-formal learners using OERs. Future research will benefit from the findings related to designing OER environments that can accommodate diverse self-directed learners.  相似文献

It is important for teachers of mathematics to know how pupils react to certain mathematical situations and what these reactions imply, in order to design more effective instructional environments based on their learning needs. This study reports the development processes of a digital learning tool (Learning Tool for Elementary School Teachers (L‐TEST)) that shows children's mathematical thinking for the ages of 4–11 years across certain problem situations. L‐TEST is designed as a support tool to be used in teacher education. A case‐based instructional model was used in designing the instructional tool. Video recordings were digitised to provide a rich environment where learners observe exemplary cases. These exemplified videos included children's mathematical development in the subjects of numbers and shapes, combined with discussions in line with the current research findings. Finally, a usability test for the learning tool was carried out.  相似文献

Understanding social presence in text‐based online learning environments   总被引：2，自引：2，他引：0  
This article reports on key aspects of a theory generative study into social presence in text‐based online learning environments. The focus of the article is the nature of social presence as experienced by online learners in those environments. Employing a collective case study design, the study accessed online learners’ experience‐based heuristic knowledge through a multi‐phase dialogical process which functioned as an extended interview. Among the key findings was (a) a definition of social presence drawn from learners’ experiences; (b) explication of the nature of social presence in online learning environments; (c) suggestions for the creation and sustenance of social presence in those environments; and (d) support for a relational view of social presence which emphasizes human agency in mediated social processes and foreshadows a role for social presence as a critical element of online learning environments.  相似文献

Advances in technology for distance learning present better‐than‐ever opportunities for designing learning environments that bring optimal features of the conventional classroom to distributed learners. Yet, with the advantages of reaching learners come corresponding challenges for meeting many and varied cognitive, motivational, and organizational needs. Anchoring design of distance learning instruction solidly in current research from cognitive science and motivation, as well as utilizing tested principles of instructional design theory, provides for optimal balance of strategic decision‐making and appropriate management of trade‐offs in design of effective learning environments. This paper shows how Bransford, Brown, and Cocking's (1999) four characteristics of effective learning environments can be developed for continuing education, to maximize learning, transfer of learning, and motivation. As illustration, I will focus on the process of translating traditional continuing education (CE) from lecture‐based, on‐site instruction to Web‐based instruction, a trend in many institutions of higher education.  相似文献

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

Current interactive learning environments cannot be accessed by learners with disabilities, in particular for students with vision disabilities. Modeling techniques are necessary to map real-world experiences to virtual worlds by using 3D auditory representations of objects for blind people. In this paper, a model to design multimedia software for blind learners is presented. The model was validated with existing educational software for these users. We describe the modeling of the real world including cognitive usability testing tasks by considering not only the representation of the real world but also modeling the learner’s knowledge of the virtual world. The software architecture is also described by using this model, displaying the components needed to impact learning. Finally, we analyze critical issues in designing software for learners with visual disabilities and propose some recommendations and guidelines.  相似文献

The Internet has recently been identified as a potential enabler of lifelong learning. Web‐based learning systems enable learners easily to access rich resources and actively participate in learning activities without time and distance limits. The main challenge in lifelong learning is providing the opportunity for discussion and collaborative knowledge construction to engage learners in acquiring and applying knowledge in the context of learning, working and collaboration. Moreover, knowledge sharing is a key component in the formation of communities of lifelong learners. Most online collaborative learning communities use Web text‐based discussion forums for knowledge sharing. However, such discussion forums are separated from the context of learning activities. Furthermore, the facilitation of beneficial dialogue through discussion forums, requires the involvement of mentors as facilitators. This study proposes an e‐book interface that enables learners easily to annotate or enter queries in a text in which questions arise, where a query context is transferred to a discussion forum. The subsequent anchors of questions are linked to a discussion forum for actuating sustained participation. A mentor finder recommends a collaborative peer based on learner knowledge level to answer the questions. Learners can also use mobile phones to access this ubiquitous discussion forum using voice/text anytime and anywhere. The experimental results showed a clear increase in the level of discussions, and most learners indicated that they benefited considerably from collaborative mentor support in an e‐book learning context through the provision of a ubiquitous discussion forum.  相似文献

This paper argues that Internet‐based instruction should not be only perceived as a cognitive tool or a metacognitive tool; rather, it can be perceived and used as an epistemological tool. When the Internet is used as an epistemological tool for instruction, learners are encouraged to evaluate the merits of information and knowledge acquired from Internet‐based environments, and to explore the nature of learning and knowledge construction. This paper further asserts that Internet‐based instruction is perceived as a way to help learners develop advanced epistemologies. On the other hand, developmentally advanced epistemological beliefs can facilitate the practice of Internet‐based instruction.  相似文献

The recent advances in software and computer technology have enabled the incorporation of dynamic representations into a multitude of educational and training environments. Cognitive load theory has been extensively used to enhance learning from complex dynamic representations by providing appropriate instructional designs to manage learner cognitive load. The available evidence, however, indicates that the suggested instructional designs that are effective for novice learners can reverse and become ineffective for learners with higher levels of prior knowledge. This phenomenon is called the expertise reversal effect. This paper reviews a series of recent experimental studies that have found interactions between levels of learners' organized knowledge structures (endogenous support) and effectiveness of different instructional designs (exogenous support), leading to the expertise reversal effect. It is argued that adapting instructional designs to learners with different amount of prior knowledge is a crucial part of effective learning.  相似文献

The purpose of this paper is to present a participatory multimedia learning model that can be used in designing multimedia learning environments that support an active learning process and creative participation. Participatory multimedia learning can be defined as learning with systems that enable learners to produce part of the learning materials themselves. The aim of the model is to represent the human information processing system and to support the transformation of free cognitive resources into a germane cognitive load needed for knowledge construction. The paper also elaborates on the results of an empirical study examining the effectiveness of student-generated illustrations. Finnish elementary school students (N = 187) learned about the human immune system by interacting with multimedia learning materials. Students performed better on a retention test when they generated their own illustrations by drawing and when explanations were presented as animations, compared to students who received only textual material or generated illustrations from images offered.  相似文献

Environmental education promotes the use of higher‐order thinking skills, encourages informal experiences in school as well as outdoors and brings together children and adults in order to make a contribution to the environment. Its holistic nature, that encompasses various subject matters, learning environments and teaching methods and encourages cognitive, affective and behavioural outcomes, requires the implementation of an appropriate assessment framework. In this study the author introduced a complex assessment method that encompasses pre, in‐ and after‐course assessments and incorporates instruments that assess knowledge, reasoning, decision‐making and the active involvement of 27 senior pre‐service science and technology teachers who participated in an environmental education course. Findings indicate that the multiple assessment modes employed expressed a wide range of learning in the course. The team investigation project was found to be most suitable for developing environmental awareness, as well as inquiry skills. Self and peer assessment enhanced critical thinking and continuous discussion. The students acknowledged the complex assessment method as a possible model for an assessment framework which corresponds to the unique nature of learning in environmental education. The assessment framework introduced included aspects of environmental knowledge as well as awareness, skills, attitudes, values and practical involvement and addressed most of the course’s basic ideas and components.  相似文献

Despite rapid and continued adoption of mobile devices, few learning modes integrate with mobile technologies and libraries' environments as innovative learning modes that emphasize the key roles of libraries in facilitating learning. In addition, some education experts have claimed that transmitting knowledge to learners is not the only educational goal, as cultivating problem-solving skills is also essential. By integrating the problem-based learning (PBL) model with book resources in libraries, one can identify the advantages of libraries in supporting e-Learning, resulting in innovative and valuable research. Therefore, this study presents a novel intelligent mobile location-aware book recommendation system (IMLBRS) with map-based guidance to support cooperative PBL in a real-library environment. Using map navigation and book recommendation functionalities, learners can search for books associated with problem-solving with increased ease and efficiency, thereby helping learners increase their PBL performance in a library environment. Experimental results reveal that learning performance during PBL supported by the proposed IMLBRS for book searches is superior to learning performance during PBL supported by the online public access catalogue (OPAC). Experimental results also show that the proposed system facilitates better learning performance for learners with a field-dependent learning style than for learners with a field-independent learning style. Moreover, the proposed system facilitates learner contemplation, cooperative learning, and library user education as learners interact with a real-library environment and peers during cooperative PBL.  相似文献
