Learning objects are instructional materials found on the Internet that can be used to illustrate, support, supplement, or assess student learning. Small in size, they can provide instruction that is just enough, just in time, just for you. Is it time to move your classroom into the twenty-first century? In this article, the author explores what learning objects are, where one might find them, and attributes of a twenty-first century curriculum. Today's students expect to use technology when learning; learning objects are a natural way to integrate technology into your classroom. 相似文献

Knowledge of the difficulties involved in processing deformable objects is necessary if learning activities are to be devised which develop visualisation skills in spatial aspects of mathematics. The research reported here attempts to determine an ordering in terms of complexity of tasks involving the mental manipulation of deformable objects, tasks which require the same skills as those employed in mathematical imagery.Subjects performed a series of spatial tests involving the comparison of diagrams of interlaced ropes, or knots at varying orientations. Knots were chosen not only because there is a mathematical structure to describe their properties but also, since they are deformable, the tasks differ from those in earlier work based upon the rotation of rigid objects.Results indicated that certain knot shapes are processed faster than others and, as with rigid objects, greater relative rotation of one of the deformable shapes increases the decision time. Tasks with more crossings were predicted to be of higher complexity, and to require longer decision times. However, this was found not to be the case, particularly where strong bilateral symmetry existed which significantly reduced decision time. 相似文献

BSP树在计算机图形学中应用于视点运动三维场景显示的计算。一般BSP树以递归的方式对平面进行分割,但实际应用的三维场景复杂度较高,也就使得树的复杂度非常高,预处理时间长。文章针对三维场景模型渲染速度慢的问题,基于空间BSP树的理论基础,通过引入包围体的方法使场景中的物体能够快速实现空间二分树划分,进而提高渲染速度。通过实验比较直接渲染和包围体渲染的速度,验证了引入包围体能够缩小预处理时间,提高场景的渲染速度。 相似文献

Associations between infants' transition to walking and object activities were examined. Fifty infants were observed longitudinally during home observations. At 11 months, all infants were crawlers; at 13 months, half became walkers. Over age, infants increased their total time with objects and frequency of sharing objects with mothers. Bidirectional influences between locomotion and object actions were found. Walking was associated with new forms of object behaviors: Walkers accessed distant objects, carried objects, and approached mothers to share objects; crawlers preferred objects close at hand and shared objects while remaining stationary. Earlier object activities predicted walking status: Crawlers who accessed distant objects, carried objects, and shared objects over distances at 11 months were more likely to walk by 13 months. 相似文献

The present study examined developmental differences in the effect of route extensity on the memory for the locations of objects in a spatial array. Kindergarten and adult subjects were trained to remember the locations of 4 objects. During this training, objects were either connected by a combination of indirect, looped train tracks and direct train tracks (experimental subjects) or connected by entirely direct train-track routes (control subjects). Analyses of actual interobject distances, from subjects' reproductions of object locations on a response board (without train tracks), revealed that children, but not adults, distort distance in terms of the nature of travel observed between objects. Further testing revealed that differences in the amount of time taken for travel could not account for the results obtained with children. 相似文献

This paper draws on the presentation of three online pilot ‘series’ of learning objects aimed at offering university staff convenient updating opportunities around issues connected with e‐learning. The ‘Hot Topics' format presented short themed sets (series) of learning objects to a wide‐range of staff, encouraging sampling strategies to support variable levels of engagement and re‐scheduling within the series which reflects each participants’ personal preferences, time or other constraints. Developed by the Institute of Educational Technology (IET) at the UK Open University, and delivered using IET's knowledge‐sharing Knowledge Network, this format suggests a new way of facilitating continuing professional development in HEIs, and also offers fresh insights into the consequences of using learning objects for staff development and the difficulties of evaluating staff development activity based on learning objects. This paper is particularly concerned with the consequences of offering choice to the series' participants and more flexible options for dissemination to potential contributors. 相似文献

Infants' visual short‐term memory (VSTM) for simple objects undergoes dramatic development: Six‐month‐old infants can store in VSTM information about only a simple object presented in isolation, whereas 8‐month‐old infants can store information about simple objects presented in multiple‐item arrays. This study extended this work to examine the development of infants' VSTM for complex objects during this same period (N = 105). Using the simultaneous streams change detection paradigm, Experiment 1 confirmed the previous developmental trajectory between 6 and 8 months. Experiment 2 showed that doubling the exposure time did not enhance 6‐month‐old infants' change detection, demonstrating that the developmental change is not due to encoding speed. Thus, VSTM for simple and complex objects appears to follow the same developmental trajectory. 相似文献

Multimodal instruction with text and pictures was compared with uni-modal, text-only instruction. More specifically, 44 students used a visual or a textual manual to learn a complex software application. During 2 103-116-min training sessions, cognitive load, and time and ability to recover from errors were measured. After training, the authors tested students' learning on trained and untrained tasks. The results for cognitive load, training time, and learning effects initially supported dual coding theory. The results show that even in this complex situation, multimodal instruction led to a better performance than unimodal instruction. That is, the multimodal manual led to a stronger mental model of the computer program, improved identification of window elements and objects, and speeded up the location of window elements and objects. 相似文献

张爱玲是一个具有鲜明的＂现代性＂倾向的作家,时间的飞快流逝经常成为她的小说的主题,因此也就出现了众多时间性场景的描述。其中以服饰、镜子等物象为代表的＂隐性时间＂和以时钟、月亮等物象为代表的＂显性时间＂,在这些时间性场景中尤为突出。张爱玲正是借助这些不同的物象,表达了她对时间的独特感悟。 相似文献

The features of collaboration in design education include effective and efficient communication and reflection, and feasible manipulation of design objects. For collaborative design, information and communication technology offers educators the possibility to change design pedagogy. However, there is a paucity of literature on relative advantages and disadvantages of online collaboration for real‐time manipulation of design objects and prototypes, particularly in web design education. Using survey instrumentations, this study investigated online collaborative design practices with an application by measuring experiences of communication and interaction among twelve designers who are enrolled in a Master's programme in interactive design. The study identified barriers to online collaboration design: (1) real‐time manipulation of design objects and prototypes may increase complexity of communication interaction; (2) records of communication and invisibility of team members may attenuate quality and frequency of critical feedback to each other; (3) students’ attitudes towards collaboration, individual students’ learning goals, and completing tasks in a timely manner could reduce their engagement and increase their reliance on teacher intervention. 相似文献

Sixty-two second-, fourth-, and sixth-graders were asked to judge the temporal duration of objects and events when the objects were changed in height or subjected to decay, when an event was reversed, and when an event was given an affective dimension. Nonconservers of time were those who judged that these irrelevant transformations affected the temporal aspects of the objects or events. The shift from nonconservation to conservation of time occurred between the second and fourth grades for most problems. The results indicated that young (under eight or nine years) children's concept of time is surprisingly defective. The relation of these findings to other conservation concepts was discussed. 相似文献

The present research investigated the development of word retrieval abilities late in the second year when most children display a marked increase in word production. When asked what was hidden in a given box, children with still quite limited productive vocabularies were reliably less likely to produce the labels of the hidden objects than were children with larger productive vocabularies even though (1) all children could name those objects and (2) all children did well when asked to find those same hidden objects. Additionally, the provision of pictorial cues facilitated word retrieval, especially in the early stage of lexical development. Naming errors during a naturalistic book-reading session peaked in children whose productive vocabularies had recently begun to expand, further suggesting that word retrieval processes undergo significant changes at this time. 相似文献

The purpose of this study was to investigate the effects of limited oral and physical teacher intervention on object manipulation by preschool and early elementary children. The population consisting of 70 children, three, four, five, and six years old from two preschools and two kindergarten classes were randomly assigned to control and experimental groups. Children were observed as they manipulated magnets in classroom settings. Experimental students had the objects placed in their hands and were orally invited to explore. Results showed that there were significant differences between the groups in total time spent with the objects, number of activities performed, and cognitive level of operation. No significant differences were found in the number of contacts or in the interactive effects of treatment and testing day. The findings suggest that teacher roles may have an effect on student exploration and quality of interaction with unfamiliar objects. 相似文献
