Online educational technologies and e‐learning tools are providing new opportunities for students to learn worldwide, and they continue to play an important role in anatomical sciences education. Yet, as we shift to teaching online, particularly within the anatomical sciences, it has become apparent that e‐learning tool success is based on more than just user satisfaction and preliminary learning outcomes—rather it is a multidimensional construct that should be addressed from an integrated perspective. The efficiency, effectiveness and satisfaction with which a user can navigate an e‐learning tool is known as usability, and represents a construct which we propose can be used to quantitatively evaluate e‐learning tool success. To assess the usability of an e‐learning tool, usability testing should be employed during the design and development phases (i.e., prior to its release to users) as well as during its delivery (i.e., following its release to users). However, both the commercial educational software industry and individual academic developers in the anatomical sciences have overlooked the added value of additional usability testing. Reducing learner frustration and anxiety during e‐learning tool use is essential in ensuring e‐learning tool success, and will require a commitment on the part of the developers to engage in usability testing during all stages of an e‐learning tool's life cycle.

Medical schools are increasingly looking to case-based formats such as problem-based learning (PBL) for their medical students. However, the effects of PBL have not been adequately assessed for an informed decision. An approach to assessment should consider not just the knowledge outcomes expected of all students, but should be tailored to the theoretical goals of PBL: clinical reasoning, integration of scientific and clinical knowledge, and lifelong learning skills. This means that problem-solving processes as well as products need to be measured. In addition, cognitive measures associated with expert performance can be used to assess the extent to which PBL affects the development of expertise. In this study, students taking an elective in PBL were compared with students taking other electives on a realistic pathophysiological explanation task. The problem-solving protocols were examined for coherence, use of science concepts, strategy use, and self-directed learning. The results indicate that cognitive measures can be used to distinguish students who have participated in PBL from their counterparts in terms of knowledge, reasoning, and learning strategies. This suggests that such measures may play a meaningful role in assessment of student learning. 相似文献

Infographics are a visualisation tool that can be used to improve retention, comprehension and appeal of complex concepts. The rise of infographic use in education has facilitated new forms of application and design of these tools. Instructor-provided summary infographics are a new form of infographic, whereby key learning objectives and content are summarised in graphical form at the end of a lesson. However, it is unknown whether these types of infographics can support learning in online environments. This exploratory research investigates student perceptions, retention, applications and activity generation of instructor-provided summary infographics in a massive online learning environment. Using both post-course learner survey data (n = 1,899) and text mining analysis (n = 72,490 words), results present how learners perceived instructor-provided summary infographics as useful and appealing for retaining, clarifying and understanding learning concepts. The research contributes a novel understanding of summary infographics in online learning environments, and supports their use as a design tool for educational delivery in the online space. 相似文献

Cognitive Load Theory and Complex Learning: Recent Developments and Future Directions 总被引：27，自引：0，他引：27
Traditionally, Cognitive Load Theory (CLT) has focused on instructional methods to decrease extraneous cognitive load so that available cognitive resources can be fully devoted to learning. This article strengthens the cognitive base of CLT by linking cognitive processes to the processes used by biological evolution. The article discusses recent developments in CLT related to the current view in instructional design that real-life tasks should be the driving force for complex learning. First, the complexity, or intrinsic cognitive load, of such tasks is often high so that new methods are needed to manage cognitive load. Second, complex learning is a lengthy process requiring learners motivational states and levels of expertise development to be taken into account. Third, this perspective requires more advanced methods to measure expertise and cognitive load so that instruction can be flexibly adapted to individual learners needs. Experimental studies are reviewed to illustrate these recent developments. Guidelines for future research are provided. 相似文献

Design-based learning is a teaching approach akin to problem-based learning but one to which the design of artefacts, systems and solutions in project-based settings is central. Although design-based learning has been employed in the practice of higher engineering education, it has hardly been theorised at this educational level. The aim of this study is to characterise design-based learning from existing empirical research literature on engineering education. Drawing on a perspective that accounts for domain-specific, idiosyncratic and learner-centred aspects of design problems in the context of engineering education, 50 empirical studies on project-based and problem-based engineering education, to which the design of artefacts is central, were reviewed. Based on the findings, design-based learning is characterised with regard to domain-specificity, learner expertise and task authenticity. The implications of this study for the practice of engineering education are discussed. 相似文献

教学之目的在促进学生之学习。有效的学习过程和显著的结果性体现构成学生的深层学习。深层学习关注学习者认知发展和深度参与。内驱力强、学习者参与度高是深层学习的外在体现。深层学习视域下中学阶段实现有效教学的主要阻点为“教”和“学”双方面投入度不足、知识灌输和认知发展不匹配、学业评价欠完备等。经过长期实践探索,要解决教育根本问题还需回到教学“根部”,创造多元性、批判性学习环境,实现学生自主参与性、学业评价多样化体系,旨在完善中学有效教学策略。 相似文献

Questioning how and why simulations can be suitable for supporting intraindividual learning and expertise development motivated this study. We depart from an empirically well supported cognitive perspective of expertise that focusses on cognitive adaptations through long-term engagement with professional work activities. The strength of simulation learning is seen in its multiple explanatory base, which is used to build the framework PETS (Promoting Expertise Through Simulation). The PETS model specifically addresses how simulations can contribute to intraindividual knowledge restructuring through case processing and learner-tailored guidance of a trainer supporting the thorough engagement in deliberate practice activities to go beyond automatization. Preparation, briefing, repetitive practice opportunities, and debriefing are phases of instructional embedding in simulation learning for which the PETS model identifies important prerequisites to enhance understanding of what works for whom under which conditions and why during expertise development. 相似文献

Starting from Perkins’ (1985) framework, this study addresses tool use in a computerbased learning environment. In line with Perkins, first the effects
of tool use on performance were investigated to gain insight into the functionality of the tools. Next, the influence of advice
was studied to identify whether this advice could make students more knowledgeable with respect to the tools, and hence encourage
them to make more (adequate) use of the tools. A third research question addressed learner related variables. The influence
of metacognitive skills, goal orientation, and instructional conceptions on students’ tool use was investigated. An experimental
design was used to address these research questions with one control group and two experimental groups, one with advice and
one without advice. Results reveal that the tools were functional, the two experimental groups outperformed the control group.
With respect to advice, the group of students receiving advice used tools more frequently and spent more time on their use.
Finally, the study reveals mastery orientation to be an important variable. The more students are mastery oriented, the less
they use tools. 相似文献

In the knowledge economy, many companies are well aware of the vital need to maintain the professional expertise of their workers at a high level. Though there have been a lot of research studies in the areas of professional expertise and workplace learning, few examined the learning pathways novice workers went through to become experts in their professions. Most of the research studies on expertise focused on the nature of expertise and few on its development. As for workplace learning research, most studies focused on the learning resources and methods workers used and the affordances of the workplace in making learning possible. Based on the accounts of expertise development collected from individual information technology (IT) workers in Hong Kong, this paper proposes a four-phase model of professional expertise development in the workplace and discusses its similarities to and differences from extant theories of expertise and skill development. 相似文献

学习是对现有知识结构的丰富和重构。丰富是现有知识对新知识的同化过程,重构则是概念改变,表现为理论的修正和改变。上述学习理论运用于教学中的一个重要方面就是设计和组织学习材料。学习材料具有多种形式,包含着与学习者固着观念相联系的同化点,能引发学习者的认知冲突,或显示新知识的特性导致概念改变,并且能提供新的情景便于学习者的知识迁移。因此综合设计和组织学习材料是促进学习者对知识进行有意义建构,提高其学习能力的关键。 相似文献

In the field of second and foreign language learning, how various task characteristics affect language learning has been the focus of many recent studies. Much of this research examined the relationship between task characteristics and task performance without fully taking into account learner related variables. The present study aimed to assess task complexity and sequence in relation to the learner related variables drawn from the social cognitive perspective of self-regulated learning, i.e. self-efficacy beliefs and frequency of learning strategy use, as they were applied to two versions of vocabulary learning from reading tasks. The tasks designed for the present study were based on the componential framework for second language task design. With tasks and task sequence counterbalanced, 146 first-year university students (mean age?=?18.59 years) were randomly assigned to one of four groups. Results reveal a significant effect of task sequence on vocabulary learning self-efficacy beliefs, frequency of learning strategy use and task performance, and a significant interaction effect of sequence with task complexity. Findings are discussed in terms of complex interactions between task and learner factors. 相似文献

The article reviews studies that explain the role of graphical displays in learning and synthesizes relevant findings into principles for effective graphical design. Three theoretical perspectives provide the framework that organizes the review: dual coding theory, visual argument, and conjoint retention. The three theories are compatible although they are based on different assumptions. Research suggests that graphics are effective learning tools only when they allow readers to interpret and integrate information with minimum cognitive processing. Learners' characteristics, such as prior subject-matter knowledge, visuospatial ability, and strategies, influence graphic processing and interact with graphical design to mediate its effects. Future research should investigate the interplay between display and learner characteristics and how graphical design can address individual differences in learning from graphics. 相似文献

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

Learner motivation is considered an important premise for learning achievement. One of the theories used to explain learner motivation in physical education is the Self-Determination Theory (SDT). Different from others, SDT acknowledges the controlling nature of institutionalized education and builds its application around externally imposed regulatory mechanisms to enhance learner motivation. In this article, we review research findings on SDT in physical education and reason for the use of externally regulated motivation approaches as a primary strategy in physical education. We frame our arguments in the constructivist learning theories and argue that using external regulation mechanisms to maximize learner motivation is not inconsistent with the constructivist learning theories. Our pedagogical understanding about satisfying the basic human needs for competence, relatedness, and autonomy leads us to believe that the priority should be placed on competence development with relatedness as a pedagogical platform for competence development in physical education. 相似文献
