This study describes the multiple analogical models used to introduce and teach Grade 12 chemical equilibrium. We examine the teacher's reasons for using models, explain each model's development during the lessons, and analyze the understandings students derived from the models. A case study approach was used and the data were drawn from the observation of three consecutive Grade 12 lessons on chemical equilibrium, pre‐ and post‐lesson interviews, and delayed student interviews. The key analogical models used in teaching were: the “school dance”; the “sugar in a teacup”; the “pot of curry”; and the “busy highway.” The lesson and interview data were subject to multiple, independent analyses and yielded the following outcomes: The teacher planned to use the students' prior knowledge wherever possible and he responded to student questions with stories and extended and enriched analogies. He planned to discuss where each analogy broke down but did not. The students enjoyed the teaching but built variable mental models of equilibrium and some of their analogical mappings were unreliable. A female student disliked masculine analogies, other students tended to see elements of the multiple models in isolation, and some did not recognize all the analogical mappings embedded in the teaching plan. Most students learned that equilibrium reactions are dynamic, occur in closed systems, and the forward and reverse reactions are balanced. We recommend the use of multiple analogies like these and insist that teachers always show where the analogy breaks down and carefully negotiate the conceptual outcomes. © 2005 Wiley Periodicals, Inc.

In language learning contexts, writing tasks that involve reading of source texts are often used to elicit more authentic integrative language use. Thus, interests in researching these read-to-write tasks in general and as assessment tasks keep growing. This study examined and modeled the process of summary writing as a read-to-write integrated task. Data of test-taking process were collected from 94 Chinese English as a foreign language (EFL) learners who completed two summarization tasks. Seven students first completed the tasks while thinking aloud their mental process. The researcher observed their test-taking process and conducted post-test interviews to learn more about how they completed the tasks. Participants’ verbal reports were coded into mental moves, which were then grouped according to their purposes. These formed the basis for identifying the processes and sub-stages participants followed while completing the tasks. Based on the analysis of the think-aloud, observation, and interview data, a questionnaire was developed containing items specifying the processes task takers went through. The questionnaire was completed by the remaining 87 participants to test the generalizability of the findings. A process model of summarization was constructed subsequently. The implications of the study are discussed with reference to construct validity of summarization tasks, EFL writing instruction and assessment. 相似文献

This study explored the effects of active learning and types of elaboration on procedure acquisition (writing database queries). Training materials emphasized elaborations of conditions for executing actions versus elaborations of the connection between conditions and actions. In the “active” conditions, participants performed structured exercises designed to encourage active processing. In the “passive” conditions, participants studied examples that contained instructional elaborations. Although excessive instructional information for more knowledgeable learners can hurt performance, our results indicate that condition–action elaborations improved procedural performance the most, in both the active and passive conditions. Active learning required longer training time but was offset by reduced test time. 相似文献

The recent and popular “Maker” movement worldwide has revived conversations about creativity, hands-on “Making,” arts and design, humans with tools and digital experiences beyond the flat-screen. However, such conversation mainly revolved outside the realm of formal education. This article presents two learning tasks, one in upper primary (age 10–11) and one in lower secondary (age 12–13), which integrate “Making” and 3D computer-aided design (CAD), thereby facilitating Science, Technology, Engineering, and Mathematics (STEM) learning in mathematics classrooms. By adopting a design-based research methodology, we examine students' mathematics learning with respect to dissecting and forming 2D shapes and volume of composite solids with the use of 3D CAD and the kinds of integrated STEM learning practices they demonstrated in the activities. Qualitative data were collected in the form of videos of the students' communication and screenshots of their initial and final designs as they engaged with the 3D CAD environment, as well as students' written reflections and teachers' lesson analysis. Results showed that the students used 3D CAD to develop spatial skills and to achieve mathematics learning far beyond using formulae and performing procedures. The learning activities also enabled an integrated STEM learning experience in productive and unobtrusive ways. 相似文献

Many teachers see major difficulties in maintaining academic standards in today's larger and more diversified classes. The problem becomes more tractable if learning outcomes are seen as more a function of students’ activities than of their fixed characteristics. The teacher's job is then to organise the teaching/learning context so that all students are more likely to use the higher order learning processes which “academic” students use spontaneously. This may be achieved when all components are aligned, so that objectives express the kinds of understanding that we want from students, the teaching context encourages students to undertake the learning activities likely to achieve those understandings, and the assessment tasks tell students what activities are required of them, and tell us how well the objectives have been met. Two examples of aligned teaching systems are described: problem‐based learning and the learning portfolio. 相似文献

This study investigated the effects of digital storytelling on student achievement, social presence, and attitude in online collaborative learning environments. Students in one middle school course were randomly assigned to one of the two treatment groups after they received initial general instruction regarding teamwork skills. The “digital storytelling-based online collaborative learning (DST-OCL)” and the “general online collaborative learning (G-OCL)” groups received subsequent associated skills training. The overall results indicated that after each group took part in the treatment during online collaborative learning activities, the “DST-OCL” groups had significantly higher social presence than the “G-OCL” groups. Specifically, using “DST-OCL” strategies was significantly more effective than using “G-OCL” strategies for improving the “online communication,” “interactivity,” and “privacy” components of students’ social presence in online collaborative learning environments. There was no significant difference between the two groups regarding student achievement and attitude. The findings of this study offer an insight into methods for using digital storytelling as an instructional strategy for improving online collaborative learning effectiveness. 相似文献

Abstract This study examined how six Singapore teachers approached the design and implementation of a unit of work (topic) to demonstrate exemplary classroom practices that engage learners and use ICT in knowledge-generative rather than presentational activities. After a reflection and feedback session on the first lesson observation involving the researcher and the teacher, the teacher redesigned the lesson to enhance ICT use and involve students more actively in their learning. Our study revealed that there is a difference between students' physical engagement and cognitive engagement in a task and that the teacher, as a designer of the learning environment, needs to make explicit the cognitive processes involved in using the tool to ensure students' effective use of ICT. The teachers' understanding of what constitutes effective learning and their roles in students' learning determine how they design the learning environment. In essence, it is the teacher's skill in managing the “tripartite” partnership of IT tool, learning task, and teacher support that brings about higher levels of student engagement. 相似文献

This study analyses the practices of nine New Zealand teachers of upper primary and middle-school students (N = 210) whose classes had consistently shown gains in writing far greater than normative expectations. Data from observations of three writing lessons and related interviews with each teacher, plus interviews with three focus students after each lesson, were considered in relation to learner gains in writing. To analyse these data, a content analysis matrix was constructed from selected writing research literature, yielding eight dimensions of effective practice: expectations; learning goals; learning tasks; direct instruction; responding to learners; motivation and challenge; organisation and management; and self-regulation. Instructional moves associated with each were defined. There was a significant association between three dimensions (learning tasks, direct instruction and self-regulation) and learner gains. Analysis also indicated that these effective teachers of writing employed an interconnected range of instructional moves in a strategic and flexible way. Instructional actions and activities are particularly effective if regarded as purposeful by learners and if they include meaningful opportunities for learner involvement. The findings detail strategies for generating higher than anticipated gains by learners. 相似文献

Mobile and Ubiquitous Learning (m/u-learning) are finding an increasing adoption in education. They are often distinguished by hybrid learning environments that encompass elements of formal and informal learning, in activities that happen in distributed settings (indoors and outdoors), across physical and virtual spaces. Despite their purported benefits, these environments imply additional complexity in the design, monitoring and evaluation of learning activities. The research literature on learning design (LD) and learning analytics (LA) has started to deal with these issues. This paper presents a systematic literature review of LD and LA, in m/u-learning. Apart from providing an overview of the current research in the field, this review elicits elements of common ground between both communities, as shown by the similar learning contexts and complementary research contributions, and based on the research gaps, proposes to: address m/u-learning beyond higher education settings, reinforce the connection between physical and virtual learning spaces, and more systematically align LD and LA processes. 相似文献

A video-based program on lesson analysis for pre-service mathematics teachers was implemented for two consecutive years as part of a teacher education program at the University of Lazio, Italy. Two questions were addressed: What can preservice teachers learn from the analysis of videotaped lessons? How can preservice teachers’ analysis ability, and its improvement, be measured? Two groups of preservice teachers (approximately 140 in total) participated in the program. A three-step lesson analysis framework was applied to three lesson videos: (1) goal(s) and parts of the lesson; (2) student learning; and, (3) teaching alternatives. Preservice teachers’ ability to analyze lessons was measured through an open-ended pre- and post-assessment. In the assessment, preservice teachers were asked to mark and comment on events (in a lesson not included in the program) that they found interesting for: teachers’ actions/decisions; students’ behavior/learning; and, mathematical content. A coding system was developed based on five criteria: elaboration, mathematics content, student learning, critical approach, and alternative strategies. In both studies, the ability to analyze instruction improved significantly on all five criteria. These data suggest promising directions for the development of both an instrument to measure lesson analysis abilities and a model for teacher learning. 相似文献

A particular difficulty in physics learning is the fact that pupils’ “intuitive” concepts are often resistant to instruction. This article reports empirical results from two related studies within an interdisciplinary project of physics education and educational psychology in ray optics. Two different kinds of treatment groups (TG A and TG B), both targeted at widespread pupils’ intuitive concepts (N?=?511), were compared with the results of a control group (CG C) learning with conventional tasks (N?=?218) provided by a related study II. Pupils in TG A) of study I worked on cognitively activating tasks related to widespread intuitive concepts in ray optics explicitly requiring them to deal with multiple representations. Pupils in the TG B) of study I worked on the same intuitive concepts, but without the cognitively activating representational component. TG A) and B) were compared with each other and with CG C) learning with conventional tasks. The results indicated that tasks addressing widespread intuitive pupils’ concepts improved conceptual understanding significantly more than conventional tasks. There was evidence of a significant intermediate effect showing medium-term stability. 相似文献

This qualitative study examined the connections between elementary teachers’ conceptions of how scientists use writing and how the teachers used writing during science lessons. Data collected included lesson observations, interviews, handouts to students, and curriculum resources. The findings revealed that teachers in this study thought scientists write for several purposes: the presentation of data, observations, experiences, procedures, and facts. The teachers used writing tasks that mirrored this with their students. The teachers also had a limited definition of creativity in writing, and when they had students write creatively in science it was to add in fictional elements. Implications of this study include providing teachers with better models for how and why scientists write, including these models in more inquiry-based science lessons, and directly relating concepts of nature of science to elementary science writing. 相似文献

Although videotapes are a popular instructional medium in the training environment, viewers often adopt a passive stance toward learning from video. Viewers perceptions of video as a passive, “easy” medium may minimize the information they gain from video-based instruction. If instructional designers and trainers want to encourage the “couch potato” to process the content of a video-based lesson in an active manner, they should make sure that their lessons are designed to facilitate this process. This article discusses the relationship of mental effort to achievement, provides recommendations for designing video-based materials to increase the effort learners invest in the instruction, and presents a list of practical techniques for increasing learners' mental effort and achievement that can be incorporated into lessons that include video-based materials. 相似文献

Young children with learning disabilities typically encounter difficulty with academic tasks requiring intentional effort and effective use of metacognitive skills--qualities that competent readers and writers possess. In response to these difficulties, special educators often modify literacy instruction, isolating the "basic skills" of literacy (such as decoding and penmanship) from meaningful reading and writing activities. Such instruction contributes to impoverished notions of literacy and exacerbates problems of metacognition. The two research programs reported here challenge the conventional literacy instruction provided to many young students with LD. The programs are rooted in developmental and cognitive theory and research, as well as emergent literacy theory. The social nature of learning is emphasized, with a focus on the role of the teacher, the form of discourse, and the role of text in literacy instruction. Results show that children with learning disabilities benefit from strategy instruction occurring within classroom cultures that support collaborative discourse, the flexible application of comprehension strategies, and appropriate, meaningful opportunities for reading and writing. 相似文献
