Students' perceptions of instructional quality have become an important information source for teachers' professional development. This requires knowledge of the structure of these perceptions, their validity, and generalizability. To this end, we conducted a study with 15,005 German 512 grade students from 690 classrooms in three different school types and three different grade levels. Assuming three basic dimensions of instructional quality with 7 facets, we investigated the factorial structure of students' perceptions with two-level confirmatory factor analyses as well as their generalizability with two-level measurement invariance analyses. Our results confirmed the postulated factorial structure and strict invariance across subject groups, school types, and grade levels. We confirmed the same structure in teachers' assessments of their instructional quality that were positively correlated with the students' assessments. As such, these findings shed light on the structure, validity, and generalizability of students’ perceptions of instructional quality.  相似文献

The increasing complexity of the subjectmatters taught through distance education calls for a cognitive approach to instructional design. Cognitive task analysis‐based instructional design (CTA‐BID) is especially appropriate for distance education, which requires high‐fidelity instructional materials that teach cognitive content with little or no classroom instruction. CTA‐BID organises instructional materials around the results of a cognitive task analysis that identifies the optimal knowledge structures, mental models, strategies, and skills underlying expertise in the subject matter. CTA‐BID has produced innovative instructional programmes aimed at teaching cognitive skills, accelerating the development of expertise, and improving student performance and training efficiency. This article provides an overview of CTA‐BID and its applications in the design of instructional and testing materials for distance education. I also review recent developments in education, psychology, and instructional design that complement CTA‐BID.  相似文献

There is now evidence to suggest that the degree to which hypertext or web‐based instructional systems facilitate recall of information appears to be contingent on an individual’s cognitive or information processing style. Concept maps also reflect the way in which individuals process information and therefore it is possible that cognitive style and hypertext architecture might influence concept map drawings produced by hypertext users. In this study, 55 participants were assigned to one of three hypertext conditions and were required to recall information and produce maps of the hypertext. Cognitive style was assessed using the analyst–intuition dimension of cognitive style. The findings confirmed earlier research that individuals possessing different cognitive styles differed in recall performance when using different hypertexts. Furthermore, the concept maps produced by participants with different cognitive styles differed between architecture conditions. The findings are explained partly as being due to differences between individuals’ perceived ease of use of hypertext.  相似文献

Recent studies have tested the addition of worked examples to tutored problem solving, a more effective instructional approach than the untutored problem solving used in prior worked example research. These studies involved Cognitive Tutors, software designed to support problem solving while minimizing extraneous cognitive load by providing prompts for problem sub-goals, step-based immediate feedback, and context-sensitive hints. Results across eight studies in three different domains indicate that adding examples to Cognitive Tutors is beneficial, particularly for decreasing the instructional time needed and perhaps also for achieving more robust learning outcomes. These studies bolster the practical importance of examples in learning, but are also of theoretical interest. By using a stronger control condition than previous studies, these studies provide a basis for refining Cognitive Load Theory explanations of the benefits of examples. Perhaps, in addition to other reasons, examples may help simply because they more quickly provide novices with information needed to induce generalized knowledge.  相似文献

Visuo-spatial text adjuncts such as static or animated pictures, geographic maps, thematic maps, graphs, and knowledge maps that have been analyzed in the articles contained in this special issue provide complex pictorial information that complements the verbal information of texts. These spatial text adjuncts are considered as depictive representations that can support communication, thinking, and learning. An essential precondition of this supportive function is that the visuo-spatial displays interact appropriately with human visual perception and the individual's cognitive system, which is characterized by prior knowledge, cognitive abilities, and learning skills. Accordingly, effective learning with visuo-spatial text adjuncts can be fostered by instructional design and by adequate processing strategies, both dependent on sufficient understanding of how the human cognitive system interacts with these displays. Perspectives for further research in this area are provided.  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.

Within the cognitive load theory framework, we designed and compared three alternative instructional solution formats that can be derived from a common static hierarchical network representation depicting problem structure. The interactive-solution format permitted students to search in self-controlled manner for solution steps, static-solution format displayed all solutions steps, and no-solution format did not have solution steps. When we matched instructional time across the formats, in relation to the complex molarity problems rather than the dilution problems, differential transfer performance existed between the static-solution or no-solution formats and the interactive-solution format, but not between the static-solution format and no-solution format. The manner in which learners interact with the static-solution and no-solution formats depends on their level of expertise in the chemistry domain. With considerable learner expertise, provision of solution steps may be redundant incurring extraneous cognitive load. Absence of the solution steps may not have left sufficient cognitive capacity for germane cognitive load as some beginning learners lacked the prior knowledge to deduce the solution steps. Searching for solution steps presumably incurred extraneous cognitive load which interfered with learning and hence, in the interactive-solution format, it outweighed the benefit of engaging in self-regulated interaction with the content. Hence, cognitive load theory is a promising tool to predict the mental load associated with learning from the three alternative computer-based instructional formats.  相似文献

Assessment of student learning in complex areas is challenging, particularly when there is interest in students’ deeper understanding and connectivity of concepts. Assessment of ethics learning has been limited by lack of consensus regarding what is effective and an overfocus on quantification at the expense of clinical or ethical relevance. Cognitive maps provide one means to evaluate depth and personal meaning of students’ ethics knowledge. A pre-/post-test design using cognitive maps and the structure of observed learning outcome (SOLO) taxonomy was used to assess student learning on completion of a six-week intensive ethics course. Thirty-seven students completed the research. Student learning was supported by significant changes in component (content, labelling, relationships and structure/visual message), and total pre- and post-test cognitive map scores, and significant change in pre- and post-test SOLO scores. A strong relationship was found between cognitive map improvement and SOLO improvement. Student written commentaries describing their post-test cognitive map provided a richer, more elaborated account of their understanding that qualitatively enhanced their cognitive maps. Cognitive maps offer an alternative to traditional ethics assessment strategies.  相似文献

Beliefs about knowledge have been found to relate to a variety of student outcomes and to vary across educational domains and instructional contexts. However, there are limited data on students’ beliefs about information and truth, vis-à-vis knowledge (i.e., epistemic beliefs) and how these beliefs differ across instructional settings. Undergraduates from two educational contexts, in the USA (n?=?240) and the Netherlands (n?=?72), participated in this study. While students in the USA were enrolled primarily in lecture and discussion classes, students in the Netherlands followed a problem-based learning curriculum. Beliefs about knowledge, information, and truth and their interrelations were examined across these two contexts through graphical and written justification tasks. Results from this exploratory study indicate that Dutch students were more likely than American students to depict knowledge, information, and truth as subjective and to define knowledge and information as synonymous. Commonalities and differences associated with educational backgrounds are considered in relation to instructional implications.  相似文献

Although it is common to see extreme case reasoning included in lists of expert heuristics for problem solving, little work has been reported on the role that extreme cases can play in learning that leads to conceptual change. Evidence is presented from video tapes of think-aloud tutoring sessions to document the learning from extreme cases in a unit about levers for seventh graders. The observations support the view that one role of extreme cases is to provide a firm data point or comparison that helps students to establish an ordinal relation between two given variables. Two new additional roles for extreme cases in fostering learning are also identified: (a) their role in activating an intuition, often in the form of a perceptual motor schema, that is used in constructing an imageable, intuitively, grounded, explanatory model as opposed to an empirical role; and (b) their role in facilitating the formation of new causal variables. Pending confirmation of similar effects in other subject areas, these roles are candidates for being included in a set of general learning strategies for science instruction. This illustrates the function that "learning-aloud" studies can play in documenting new types of learning processes and instructional strategies. The study highlights the importance for instructional design of research that uncovers students' existing knowledge structures and natural reasoning processes. The study suggests that explanatory model construction, causal relation construction, and concept formation can result from such instructional designs. The extent to which these three outcomes are evidence for strong conceptual change is also discussed.  相似文献

Learning through writing is a way of learning not only the appropriate written expression of disciplinary knowledge, but also the knowledge itself through reflection and revision. This study investigates the quality of a writing experience provided to university students in a first-year biology subject. The writing instruction methodology used is Genre-based literacy pedagogy, designed to help both with learning disciplinary knowledge and its appropriate written presentation. Evaluative research methodologies from Student Learning Research are used and include the use of three closed-ended questionnaires and an open-ended questionnaire. The results of the research suggest ways of improving the writing instruction by better understanding the previous writing experiences of the students, improving the instructional materials, clarifying goals of the writing tasks at key stages in the writing process, and helping students to improve their approach to the writing experience.in final form: 23 August 2004  相似文献

The Cognitive-Situative Divide and the Problem of Conceptual Change   总被引:1,自引:1,他引:0  
In this article we argue that both the cognitive and situative perspectives need to be modified to account for the empirical evidence on learning, taking as a central example the problem of knowledge transfer. Our proposal is that we need an approach that takes as a unit of analysis the individual in a constructive interaction with the world through a variety of mediated symbolic structures, some internal and some external, in rich sociocultural settings. This should be done without denying that knowledge can be represented in some form in the memory system. While internal mental structures are acceptable in this framework, concepts should not be seen as stable and unchanging but, rather, as flexible, malleable, and distributed. To explain conceptual change, we should allow for the possibility that what is already known can be radically restructured and that new, qualitative different structures emerge. Teaching for conceptual change, we argue, should utilize but cannot solely rely on cognitive apprenticeship types of methods. Attention must be paid to the appropriate design of curricula and to the acquisition of subject matter knowledge, together with the development of instructional methods that utilize socio-cultural processes, like classroom discussion, to develop students' metaconceptual awareness and the ability to engage in intentional learning.  相似文献

The main task of an educational system is to generate instructional situations which induce students to learn knowledge and problem solving abilities as applied to a cognitive domain.
To this end, an instructional dialogue must be seen as a process aimed at making student and teacher learn from each other: the student has to learn the subject matter from the teacher, while the teacher has in turn to learn from the student how to regulate instructional interaction. The process relies on different kinds of expert knowledge: experience of the domain, about the actual student, and of teaching methods and objectives. This means that an instructional dialogue cannot be realised without an explicit representation of all the kinds of knowledge involved.
Research has established that Knowledge Based Educational Systems (KBESs) can be the keystone in building effective learning tools, but because of the difficulty in realising a system of this kind, most existing systems are prototypes and are intended only as workbenches for the computational analysis of educational processes.
This paper analyses the main problems which underlie the realisation of such systems, with reference to research into knowledge based systems intended for use with teaching/learning mathematics.  相似文献

Several cognitive psychologists have written about the importance of placing instruction within “authentic” contexts that mirror real-life situations. They argue that knowledge learned in academic settings does not necessarily transfer to non-academic settings. Whether preparing performance technologists or instructional designers, educators must strive to create meaningful problem-solving contexts that enable students to define, and subsequently solve, real-world problems. In an attempt to address this issue we have modified the way we teach instructional design. This paper discusses a cognitive apprenticeship approach to teaching design, which incorporates elements of modeling, coaching, reflection, articulation, and exploration. We describe how these features are embedded within three phases (orientation, situated training/learning, and exploration) of an introductory instructional design course designed to move our novice designers along a continuum of expertise as they develop and refine their own professional design skills. Although the apprenticeship model described here specifically addresses concerns within the context of preparing instructional designers, we believe that this model can be adapted to address similar issues in the education of performance technologists.  相似文献

The purpose of this study was to examine relationships between structural characteristics of students' concept maps about chemical equilibrium and independent measures of their achievement in chemistry. Fifty students in 1991 and seventy students in 1992 completed a concept-mapping task using twenty-four specified concepts. Using similarities in concept map structure, based on the presence or absence of linked pairs of concepts, non-metric multidimensional scaling (MDS) was used to plot the location of the concept maps in coordinate space. The distribution of maps was based on differences in their structure, but also reflected levels of student achievement on independent tests. The relationship between the coordinate location of each student's maps and his or her test scores on independent chemistry achievement tests was sought by canonical correlation analysis of the 1991 data set. This revealed significant relationships between the MDS coordinates and test scores of recall of knowledge and its application. Multiple regression analysis of sixty-one students' maps from the 1992 data set against their percentile rank scores on a national chemistry quiz revealed significant relationships. The results are interpreted as revealing structural differences in conceptual organisation about chemical equilibrium among students with different levels of achievement and thus relative expertise in the domain. The significant relationship between map structure and cognitive process scores in chemistry also supports the view that the organisation of declarative knowledge influences its accessibility in cognitive tasks.  相似文献

Knowledge elaboration: A cognitive load perspective   总被引:3,自引:3,他引:0  
The process of knowledge elaboration is considered from the perspective of cognitive load theory. This theory assumes that the available knowledge structures in long-term memory (LTM) are used to organize and guide cognitive processing in complex learning. Accordingly, the role of external instructional guidance in the process of knowledge elaboration could be described as providing a substitute for knowledge structures missing from LTM. Thus, the executive guidance in complex learning environments is shared between the person (based on his/her LTM knowledge structures) and another expert or instructional means. This article analyzes instructional implications of this assumption. Adaptive learning environments are suggested for tailoring knowledge elaboration processes to changing characteristics of individual learners. Means for identifying and predicting the learner's LTM-based executive guidance are proposed so that they can be utilized in the building of adaptive learning environments.  相似文献

This article reviews some problems in aptitude treatment interaction (ATI) research, which is the knowledge base for adaptive instruction. Inconsistent ATI results were attributed to findings indicating that varying instructional methods do not necessarily invoke different types or frequencies of cognitive processing of instruction nor are individual difference measures consistently related to such processing. It is suggested that more consistent processing, and more replicable ATIs may be found by training students in the cognitive processes presumed to be invoked by instructional methods. Finally, it is suggested that the inclusion of affective variables in research on cognitive processing of instruction may lead to findings of more effective and consistent processing by students and to more reliable ATIs.  相似文献
