    One of the key reasons that multimedia, and particularly hypertext systems, are gaining in importance is that they inspire hopes of optimizing learners' processes of knowledge construction. The present study is concerned with the respective influence of individual learner variables (i.e. particularly domain‐specific prior knowledge) on the use of different design attributes. Thirty‐six university students worked through a hierarchically structured two‐part hypertext about the psychology of memory under two experimental browsing conditions (reduced versus free browsing). Results show that deeper‐level comprehension (i.e. structural knowledge) was predicted by the interaction of experimental condition and prior knowledge, but that simply retaining facts was not. Participants with low prior knowledge performed better on the comprehension test if they had worked on the version with reduced access. Moreover, the version with reduced access helped to reduce feelings of disorientation. The measure of disorientation also appeared to be closely linked with the individual's computer experience, self‐concept of computer ability and subject‐related interest. The main implications for educational practice relate to the design of an adaptive multimedia and hypertext learning system and the successful learning with it

    A theoretical view on concept mapping

    Get PDF
    Auto‐monitoring is the pivotal concept in understanding the operation of concept maps, which have been used to help learners make sense of their study and plan learning activities. Central to auto‐monitoring is the idea of a ‘learning arena’ where individuals can manipulate concept representations and engage in the processes of checking, resolving and confirming understandings. The learner is assisted by familiar metaphors (for example, networks) and the possibility of thinking ‘on action’ while ‘in action’. This paper discusses these concepts, and concludes by arguing that maps are part of the process of learning rather than a manifestation of learning itself. Auto‐monitoring is suggested as an appropriate term to describe the process of engaging in the learning arena

    This dissertation project used 80 undergraduate students to examine the effectiveness of three forms of facilitation in hypermedia learning with text and diagrams about the human circulatory system: 1) signaling key terms, 2) prompted referencing of diagrammatic representations, and 3) integration scaffolding which provided facilitation in locating corresponding components within diagrams. These three experimental manipulations were compared to a control condition in which learners used the same hypermedia learning environment, without any facilitative feature in coordinating between text and diagrams. Two measures captured differences in learning: 1) a multiple choice pretest and posttest of declarative and conceptual knowledge and 2) a diagram interpretation task requiring learners to use diagrams to explain their understanding of the circulatory system. Eye-tracking measures and concurrent think-aloud protocols were collected during the 20-minute learning sessions to provide process measures of students\u27 learning and a self-report cognitive load measure was administered immediately after the learning session. Results indicated that the integration scaffolding condition led to higher posttest scores on the multiple choice measure, but no significant differences were detected for the diagram interpretation task. Eye-tracking results demonstrated that the integration scaffolding condition had a higher number of and a higher total duration of fixations on relevant areas within the diagrams. The relevant areas represent diagrammatic representations corresponding to the textual referents within the accompanying text. Additionally, these learners spent a significantly larger proportion of their time inspecting diagrams looking at the relevant areas of the diagrams and a significantly larger proportion of these learners\u27 fixations were on relevant areas. Analyses of learners\u27 self-regulated learning processes, based on concurrent think-aloud protocols, indicated that the integration scaffolding condition also generated more correct summarizations than the remaining groups. The self-report cognitive load measure failed to reveal any differences among the learning conditions. Taken together, these results provide support for models of text-picture integration (Mayer, 2005; Schnotz, 2005) and, to some extent, Cognitive Load Theory. Further, the experiment suggests that directing learners\u27 attention to corresponding elements within text and diagrams can be an effective technique for facilitating the process of text-picture integration

    The use of additional information in problem-oriented learning environments

    Self-directed learning with authentic and complex problems (problem-oriented learning) requires that learners observe their own learning and use additional information when it is appropriate – e.g. hypertextual information in computer-supported learning environments. Research results indicate that learners in problem-oriented learning environments often have difficulties using additional information adequately, and that they should be supported. Two studies with a computer-supported problem-oriented learning environment in the domain of medicine analyzed the effects of strategy instruction on the use of additional information and the quality of the problem representation. In study 1, an expert model was used for strategy instruction. Two groups were compared: one group with strategy modeling and one group without. Strategy modeling influenced the frequency of looked-up hypertextual information, but did not influence the quality of learners' problem representations. This could be explained by difficulties in applying the general hypertext information to the problem. In study 2, the additional information was presented in a more contextualized way as graphical representation of the case and its relevant concepts. Again, two groups were compared: one with a strategy instruction text and one without. Strategy instruction texts supported an adequate use of this graphical information by learners and had an effect on the quality of their problem representations. These findings are discussed with respect to the design of additional help systems in problem-oriented learning environments

    Rich environments for active learning: a definition

    Get PDF
    Rich Environments for Active Learning, or REALs, are comprehensive instructional systems that evolve from and are consistent with constructivist philosophies and theories. To embody a constructivist view of learning, REALs: promote study and investigation within authentic contexts; encourage the growth of student responsibility, initiative, decision making, and intentional learning; cultivate collaboration among students and teachers; utilize dynamic, interdisciplinary, generative learning activities that promote higher-order thinking processes to help students develop rich and complex knowledge structures; and assess student progress in content and learning-to-learn within authentic contexts using realistic tasks and performances. REALs provide learning activities that engage students in a continuous collaborative process of building and reshaping understanding as a natural consequence of their experiences and interactions within learning environments that authentically reflect the world around them. In this way, REALs are a response to educational practices that promote the development of inert knowledge, such as conventional teacher-to-student knowledge-transfer activities. In this article, we describe and organize the shared elements of REALs, including the theoretical foundations and instructional strategies to provide a common ground for discussion. We compare existing assumptions underlying education with new assumptions that promote problem-solving and higher-level thinking. Next, we examine the theoretical foundation that supports these new assumptions. Finally, we describe how REALs promote these new assumptions within a constructivist framework, defining each REAL attribute and providing supporting examples of REAL strategies in action

    AN EXAMINATION OF THE IMPACT OF COMPUTER-BASED ANIMATIONS AND VISUALIZATION SEQUENCE ON LEARNERS' UNDERSTANDING OF HADLEY CELLS IN ATMOSPHERIC CIRCULATION

    Research examining animation use for student learning has been conducted in the last two decades across a multitude of instructional environments and content areas. The extensive construction and implementation of animations in learning resulted from the availability of powerful computing systems and the perceived advantages the novel medium offered to deliver dynamic representations of complex systems beyond the human perceptual scale. Animations replaced or supplemented text and static diagrams of system functioning and were predicted to significantly improve learners' conceptual understanding of target systems. However, subsequent research has not consistently discovered affordances to understanding, and in some cases, has actually shown that animation use is detrimental to system understanding especially for content area novices (Lowe 2004; Mayer et al. 2005). This study sought to determine whether animation inclusion in an authentic learning context improved student understanding for an introductory earth science concept, Hadley Cell circulation. In addition, the study sought to determine whether the timing of animation examination improved conceptual understanding. A quasi-experimental pretest posttest design administered in an undergraduate science lecture and laboratory course compared four different learning conditions: text and static diagrams with no animation use, animation use prior to the examination of text and static diagrams, animation use following the examination of text and static diagrams, and animation use during the examination of text and static diagrams. Additionally, procedural data for a sample of three students in each condition were recorded and analyzed through the lens of self regulated learning (SRL) behaviors. The aim was to determine whether qualitative differences existed between cognitive processes employed. Results indicated that animation use did not improve understanding across all conditions. However learners able to employ animations while reading and examining the static diagrams and to a lesser extent, after reading the system description, showed evidence of higher levels of system understanding on posttest assessments. Procedural data found few differences between groups with one exception---learners given access to animations during the learning episode chose to examine and coordinate the representations more frequently. These results indicated a new finding from the use of animation, a sequence effect to improve understanding of Hadley Cells in atmospheric circulation

    Effect Of Instructor-Provided Concept Maps And Self-Directed Learning Ability On Students Online Hypermedia Learning Performance

    The purpose of this experimental study was to explore the instructional effectiveness of integrating varied instructor-provided concept maps into an online hypertext learning environment, and the effect of learners self-directed learning abilities on their learning performance. The research adopted a randomized posttest with two-control-group design. Two major instructional treatments were traditional and interactive concept maps embedded in the online hypertext material. One hundred twenty-six undergraduate students from a public university in the U.S. participated in the study. Student participants were segregated into two levels of self-directed learning groups. Three criterion tests, including identification, terminology, and comprehension tests, were used to measure students learning performance. Results indicated that (a) the interactive concept map was superior to the traditional concept map in facilitating students knowledge acquisition, (b) students self-directed learning abilities did not influence their learning performance, and (c) the concept mapping strategy did not increase students self-directed learning abilities

    In recent years, interest in self-regulated learning has risen considerably. While self-regulatory activities are controlled cognitively, they encompass more than the monitoring of cognitive activities. Motivational and emotional processes are also important in learning and they too need to be regulated. At the same time, multimedia computer programs and theInternet have come to play un important role in present day 's learning environments. The question therefore arises as to what extent these new technologies facilitate the acquisition and improvement of self-regulated learning strategies. In the present article, we first explore the field of self-regulated learning and then try to come up with un answer to the question posed.En los Ășltimos años, el interĂ©s por el aprendizaje autorregulado se ha desarrollado considerablemente. Aunque las actividades autorreguladas son controladas cognitivamente, abarcan mĂĄs que el control de las actividades cognitivas. Los procesos motivacionales y emocionales tambiĂ©n son importantes en el aprendizaje y tambiĂ©n requieren ser controlados. Al mismo tiempo los programas multimedia e Internet han logrado unpapel importante en los entornos de aprendizaje y se presenta la pregunta de si las nuevas tecnologĂ­as facilitan la adquisiciĂłn y el perfeccionamiento de las estrategias autorregulativas. En este articulo exploramos primero el campo de aprendizaje autorregulado y despuĂ©s tratamos de dar una respuesta a la pregunta planteada
