In an experiment with N = 192 university students, we examined whether the effects of incorporating retrieval into learning tasks depend on the learning tasks' complexity. The learning tasks consisted of adjunct questions that were provided together with expository texts relating to the domain of chemistry. We varied (a) whether the adjunct questions required the learners to summarize (low complexity) or generate inferences on the basis of provided information (high complexity) and (b) whether the adjunct questions were implemented in a closed-book style that required learners to engage in retrieval or in an open-book style that did not require learners to engage in retrieval while responding to the questions. Afterwards, all learners took either an immediate or a delayed criterion test. We found that the effect of incorporating retrieval depended on the complexity of the adjunct questions; the net benefit of incorporating retrieval was higher for the low complexity ones. 相似文献

Concreteness fading has been proposed as a general instructional approach to support learning of abstract mathematics and science concepts. Accordingly, organizing external knowledge representations in a three-step concrete-to-idealized sequence should be more beneficial than the reverse, concreteness introduction, sequence. So far, evidence for the benefits of concreteness fading come mainly from studies investigating learning of basic mathematics concepts. Studies on learning natural science concepts are scarce and have not implemented the full three-step-sequence. In an experimental classroom study (N = 70), we compared concreteness fading and concreteness introduction in high school science education about electromagnetic induction using a detailed assessment. Furthermore, we explored whether these sequences differentially affect the use of the different representations during instruction. Both sequences were equally effective and there were no differences in using the representations. We discuss why our results question the proposed advantages of concreteness fading and highlight conceptual differences and learning goals across domains. 相似文献

We examined how self-regulated learning (SRL) and externally-facilitated self-regulated learning (ERL) differentially affected
adolescents’ learning about the circulatory system while using hypermedia. A total of 128 middle-school and high school students
with little prior knowledge of the topic were randomly assigned to either the SRL or ERL condition. Learners in the SRL condition
regulated their own learning, while learners in the ERL condition had access to a human tutor who facilitated their self-regulated
learning. We converged product (pretest-posttest shifts in students’ mental models and declarative knowledge measures) with process (think-aloud protocols) data to examine the effectiveness of self- versus externally-facilitated regulated learning. Findings
revealed that learners in the ERL condition gained statistically significantly more declarative knowledge and that a greater
number of participants in this condition displayed a more advanced mental model on the posttest. Verbal protocol data indicated
that learners in the ERL condition regulated their learning by activating prior knowledge, engaging in several monitoring
activities, deploying several effective strategies, and engaging in adaptive help-seeking. By contrast, learners in the SRL
condition used ineffective strategies and engaged in fewer monitoring activities. Based on these findings, we present design
principles for adaptive hypermedia learning environments, engineered to foster students’ self-regulated learning about complex
and challenging science topics.

Learning can be seen as a task-oriented process which often requires the reorganization of existing knowledge, usually referred to as conceptual change. This paper describes a theoretical framework for the analysis of conceptual change that considers conceptual knowledge as a generative cognitive tool for the creation of more specific mental representations — propositional symbolic structures and analog mental models. According to this view, conceptual change is based on a task-oriented interaction between these different kinds of mental representations. The assumption is made that it is possible to foster conceptual change by presenting to students well-defined tasks that stimulate the construction of elaborated mental models as well as an intensive interaction between these models and the corresponding propositional representations. In order to test this assumption an empirical study was conducted, in which subjects had to express their prior knowledge about a complex subject matter from the field of geography (time differences on the earth), which contained various conceptual deficits. The subjects were then randomly assigned to different groups who received the same learning material but had to solve different learning tasks requiring differently structured mental models. Afterwards, the subjects were asked to express their knowledge about the subject matter again and were tested for understanding with a comprehension test. The results support the view that a task-oriented interaction between propositional structures and mental models can help learners to evaluate the consistency of their conceptual knowledge. Accordingly, conceptual deficits result in the formation of mental models with an inadequate structure. Such deficits can be detected if the respective model is used in a sufficiently variable way, whereas they can remain unnoticed if it is used in a limited manner. 相似文献

While collaborating with a peer can be highly beneficial for learning, more work is needed to understand how instructional activities in collaborative contexts should be designed so as to maximize learning outcomes. To address this, we investigated the impact of different types of preparatory and cognitively engaging tasks on learning from collaborating, using a 2 × 2 experimental study conducted in situ in four introductory psychology classes. We compared individual preparation versus no-preparation and “active” versus “constructive” tasks. A dyadic multilevel analysis showed that preparation prior to collaborating led to better deep learning outcomes, but that the type of preparation did not have a significant effect. We include an exploratory analysis of student dialogues during collaboration to further interpret our findings. We propose that a cognitively engaging preparation phase may lead to better learning because it encourages students to collaborate constructively even when the type of task does not elicit such engagement. 相似文献

An animation can have an informational advantage over a static picture by depicting dynamic features. The aim of this study was to investigate whether the provision of prerequisite knowledge can help learners infer dynamic features from a static picture. It was assumed that this supposedly more active processing with a static picture would result in longer lasting knowledge representations. A 2 × 2 × 2 between-subjects design with visualization format (static picture vs. animation), prerequisite knowledge (provided vs. not provided), and time of testing (immediate vs. one week later) was used (N = 260). The results of a transfer test showed that learners with low prerequisite knowledge benefited from the animation, but this was not the case for learners with high prerequisite knowledge. Time of testing had no influence. In line with the expertise reversal effect, prerequisite knowledge not only fostered learning with the static picture but also hindered learning with the animation. 相似文献

ABSTRACTThis article is based on a preliminary action research (AR) study conducted with selected schools in Limpopo. It intends to report on the progress made and research problem identified during the reconnaissance/preliminary study. The aim of this preliminary research is to ascertain whether the findings conform to the main research question of the overall research. The study focused on senior phase Technology teachers at four identified schools, who are teaching grades 8 and 9 in Limpopo. This investigation entailed the administering of a questionnaire, conducting interviews and engaging in an observation activity. This was a small-scale study, for fact-finding purposes, before the main rollout of AR commences. It was evident from the study that teachers lacked capacity to teach Technology as a subject. The teachers lacked Technology pedagogical content knowledge (TPCK) and were not confident in engaging with practical activities, in their assessment of the learners and with compiling Technology learning programmes. These identified challenges serve as the main drive of the study. It is imperative to engage in an emancipatory paradigm or critical theory as a way to intervene in the challenges faced by Technology teachers. 相似文献

Model-based learning (MBL) has an established position within science education. It has been found to enhance conceptual understanding and provide a way for engaging students in authentic scientific activity. Despite ample research, few studies have examined the cognitive processes regarding learning scientific concepts within MBL. On the other hand, recent research within cognitive science has examined the learning of so-called relational categories. Relational categories are categories whose membership is determined on the basis of the common relational structure. In this theoretical paper, I argue that viewing models as relational categories provides a well-motivated cognitive basis for MBL. I discuss the different roles of models and modeling within MBL (using ready-made models, constructive modeling, and generative modeling) and discern the related cognitive aspects brought forward by the reinterpretation of models as relational categories. I will argue that relational knowledge is vital in learning novel models and in the transfer of learning. Moreover, relational knowledge underlies the coherent, hierarchical knowledge of experts. Lastly, I will examine how the format of external representations may affect the learning of models and the relevant relations. The nature of the learning mechanisms underlying students’ mental representations of models is an interesting open question to be examined. Furthermore, the ways in which the expert-like knowledge develops and how to best support it is in need of more research. The discussion and conceptualization of models as relational categories allows discerning students’ mental representations of models in terms of evolving relational structures in greater detail than previously done. 相似文献

Learning paths have the potential to play an important role in the way educators serve their learners. Empirical research about learning paths is scarce, particularly in a secondary education setting. The present quasi-experimental study took place in the context of a biology course involving 360 secondary school students. A 2?×?2 factorial research design was adopted. Learners were engaged in learning activities in a learning path. These learning activities (1) differed in design and (2) were either undertaken individually or collaboratively. Gender was considered as a critical co-variable, given the focus on science learning. All learning paths were developed on the basis of visual representations, but in the experimental design conditions, learners worked with learning paths designed according to Mayer's multimedia guidelines (2003). Multilevel analyses were applied to study the impact on learning outcomes according to the design of learning paths, the individual/collaborative setting, and the co-variable gender. The study provides empirical evidence that both the design and the group setting (collaborative versus individual) have an impact on learning outcomes. Although there was no main effect, several significant interaction effects with gender were found. The results are helpful to direct research about the design and implementation of learning paths in a secondary school setting and underpin the relevance of representation modes in science learning. 相似文献

In a study investigating different ways to engage students in an individual preparation activity, we assessed learning from collaboration with a peer. Learning was measured at pretest, individual preparation, collaboration, and posttest. Two conditions were compared: generative preparation and nongenerative preparation. With no differences in knowledge at pretest, we found that students who prepared by engaging in the generative compared to the nongenerative preparation task performed worse to a statistically significant degree in both the preparation and collaboration phases. However, in a postactivity transfer task, the students performed to a similar degree as the comparison group evidencing productive failure. In addition, students in the generative condition showed greater learning gains from the preparation to the collaboration phase. We introduce the notion that generative preparation may better invoke learning mechanisms that help students to learn from subsequent collaboration. 相似文献

Providing test questions after an initial study phase is a common instructional technique. In theory, questions that require higher-level (deep) processing should be more beneficial than those that require lower-level (shallow) processing. However, empirical evidence on the matter is inconsistent. To shed light on two potential reasons for these inconsistencies, we conducted an experiment (N = 81) to analyze the role of (a) the share of information to which test questions direct learners and (b) the learning activities performed in the initial study phase with respect to the effects between higher- and lower-level test questions. We found that both the share of focused information and the initial learning activities moderated the effects between higher- and lower-level test questions. 相似文献

In two experiments, eye tracking was used to investigate whether learners construct a mental representation during learning that integrates information from text and pictures. The experimental groups received inconsistent text-picture information on one or two pages of the learning materials. The control groups received only consistent text-picture information. It was expected that learners of the experimental groups should have difficulties in integrating text-picture information when faced with the inconsistencies. This should be reflected in their gaze behavior. Experiment 1 (N = 51) and Experiment 2 (N = 45) confirmed that assumption for several eye tracking variables. Regarding learning outcomes, only in Experiment 1 worse performance of the experimental group was observed. Furthermore, Experiment 2 revealed that the majority of learners did not remember the inconsistency between text and picture when asked for it after learning. In sum, the results add to our understanding about the cognitive processes underlying multimedia learning. 相似文献

We present a teaching sequence aimed at helping pupils (13–14 years) to put into practice the activities of building and using models. Objects (particles) characterised by invariant properties (shape, dimensions, mass) are proposed as the basic elements for building models. We hypothesised that the invariance of the properties of particles would lead pupils to introduce a variability in relations between particles in order to take into account the tranformations observed. The designed learning sequence includes activities for the production of iconic representations, discussion of the relevance of these representations in relation to the phenomena observed and the use of such representations as a predictive tool. The results show the various stages in establishing the meaning of the initial axiom; they enable us to discuss the hypotheses underlying this teaching-learning sequence. 相似文献

This article reports on key aspects of a theory generative study into social presence in text‐based online learning environments. The focus of the article is the nature of social presence as experienced by online learners in those environments. Employing a collective case study design, the study accessed online learners’ experience‐based heuristic knowledge through a multi‐phase dialogical process which functioned as an extended interview. Among the key findings was (a) a definition of social presence drawn from learners’ experiences; (b) explication of the nature of social presence in online learning environments; (c) suggestions for the creation and sustenance of social presence in those environments; and (d) support for a relational view of social presence which emphasizes human agency in mediated social processes and foreshadows a role for social presence as a critical element of online learning environments. 相似文献

Several studies have documented prospective teachers’ (PSTs) difficulties in offering instructional explanations. However,
less is known about PSTs’ learning to provide explanations. To address this gap, we trace changes in the explanations offered
by a purposeful sample of PSTs before and after a mathematics content/methods course sequence. Consistent with prior research,
our study reveals the limitations in PSTs’ explanations at their entrance to the course sequence. It also documents PSTs’
progress in providing explanations, thus providing existence proof that this practice is learnable. Using evidence from multiple
sources, we also propose a component entailed in this learning—learning how to unpack one’s thinking through the use of representations
as explanatory tools—and four factors associated with it, including PSTs’ subject-matter knowledge, active and deliberate
reflection on practice, productive images for engaging in this work, and productive dispositions about engaging in this practice.
We discuss the implications of our findings for teacher education and offer directions for future research. 相似文献

ABSTRACT While retrieval practice has been studied for over a century, it has gained a significant body of research within the past fifteen years in cognitive psychology and the learning sciences. However, there is little discussion in its study and application within topics of adult learning. In this article, we examine the historical and philosophical foundations of self-directed learning and retrieval practice and advocate for functional contextualism as a philosophy of science for self-directed learning research. Functional contextualism provides a synthesis between the norms of humanism and the scientific focus of cognitivism. Particularly, we look at retrieval practice as a potential area of research within self-directed learning, viewing it as an ‘act-in-context’. We hope this article reinvigorates research into self-directed learning, particularly the investigation of empirically-based self-guided learning strategies, the facilitation of metacognition for self-directed adult learners, and the adoption of a functional contextual approach to self-directed learning and other adult learning topics. 相似文献

Learning from texts is an important part of STEM education, but linguistic text features can affect comprehension and learning. We synthesized 45 experimental studies that investigated the effect of linguistic modifications on STEM text comprehension and learning, with a total of N = 6477 learners. In a meta-regression, we distinguished between eight categories of linguistic modifications and several other moderators, including prior knowledge. We found a small positive mean effect of linguistic modifications (g = 0.15). In line with previous research, the results showed that learners with low content prior knowledge benefited more from linguistic modifications. Personalization and increasing clarity and elaboration had positive effects, while reducing complexity and increasing cohesion did not have significant effects. This study highlights the potential and limits of linguistic modifications in STEM texts and provides implications for educational practice. 相似文献

This study examines the effectiveness of three scaffolding conditions on adolescents’ learning about the circulatory system
with a hypermedia learning environment. One hundred and eleven adolescents (n = 111) were randomly assigned to one of three scaffolding conditions (adaptive scaffolding (AS), fixed scaffolding (FS),
or no scaffolding (NS)) and were trained to use a hypermedia environment to learn about the circulatory system. Pretest and
posttest data were collected to measure the qualitative changes in students’ mental models of the topic and quantitative changes
in their declarative knowledge. Verbal protocols were collected during the 40-minute learning task to examine how each condition
affected the way in which students regulated their learning. Findings revealed that learners in both the AS and NS conditions
gained significantly more declarative knowledge than did those in the FS condition. Also, the AS condition was associated
with shift in learners’ mental models significantly more than the other conditions. Associated with these significant shifts
in their mental models, learners in the AS condition regulated their learning by planning and activating prior knowledge,
monitoring their cognitive activities and their progress toward learning goals, using several effective strategies, and engaging
in adaptive help-seeking. By contrast, those in the NS condition used fewer effective strategies, while those in the FS regulated
their learning by using several regulatory processes which seemed to impede their learning. Implications for the design of
scaffolds for fostering students’ self-regulated learning with hypermedia are presented. 相似文献

The R2D2 method—read, reflect, display, and do—is a new model for designing and delivering distance education, and in particular, online learning. Such a model is especially important to address the diverse preferences of online learners of varied generations and varied Internet familiarity. Four quadrants can be utilized separately or as part of a problem‐solving process: the first component primarily relates to methods to help learners acquire knowledge through online readings, virtual explorations, and listening to online lectures and podcasts. As such, it addresses verbal and auditory learners. The second component of the model focuses on reflective activities such as online blogs, reflective writing tasks, self‐check examinations, and electronic portfolios. In the third quadrant, visual representations of the content are highlighted with techniques such as virtual tours, timelines, animations, and concept maps. Fourth, the model emphasizes what learners can do with the content in hands‐on activities including simulations, scenarios, and real‐time cases. In effect, the R2D2 model is one means to organize and make sense of the diverse array of instructional possibilities currently available in distance education. It provides new ways of learning for diverse online students, and demonstrates easy‐to‐apply learning activities for instructors to integrate various technologies in online learning. When thoughtfully designed, content delivered from this perspective should be more enriching for learners. The R2D2 model provides a framework for more engaging, dynamic, and responsive teaching and learning in online environments. 相似文献

Structural features of learning tasks are relevant for problem solving but not salient for novice learners. Feedback in the form of Knowledge of Correct Response (KCR) during practice is expected to help learners recognize the structural features and to profit from learner control over the selection of learning tasks. A 2 × 2 factorial experiment (N = 118) was conducted to study the effects of the KCR feedback (present and absent) and control over the selection of learning tasks (learner control and program control). The presence of the KCR feedback yielded higher efficiency on a near-transfer test as well as higher learner motivation. An interaction between feedback and control, indicating extra beneficial effects of feedback when learners control the selection of learning tasks, was not found. Theoretical and practical implications are discussed. 相似文献
