超媒体环境下自主学习有效干预模式研究——扶助式学习与英语阅读 总被引：1，自引：0，他引：1
近年来,自主学习逐渐成为学术界的一个热点问题。然而,超媒体环境下自主英语学习的有效干预模式研究却为数不多。本研究探讨超媒体环境下扶助式学习与英语阅读的关系,某综合性高校经选取的某班30名大学本科学生被随机分为两组：即无扶助学习组（NS）及概念建构组（CS）,均要求在半小时的时间内在超媒体环境下学习有关美国文化的内容。数据收集工具为有声思考法。结果显示,30分钟的自主阅读过程中,CS组的学生无论是在学习计划、学习监控,还是学习策略的使用上,都显著的高于NS组的学生;两组同学在各项学习监控指标上都呈下降趋势。研究结果还证明,有声思考法是考察超媒体环境下自主阅读过程的有效方法。 相似文献

The study investigates immediate and delayed effects of different hypermedia glosses on incidental vocabulary learning and
reading comprehension of advanced foreign language learners. Sixty-nine freshman TEFL students studying at a Turkish university
were randomly assigned to three types of annotations: (a) definitions of words, (b) definitions coupled with associated pictures,
and (c) definitions coupled with associated short videos. Subjects were asked to read an annotated text with the intention
of comprehension. The data were collected through a vocabulary pre-test, a vocabulary post-test, a delayed vocabulary test
as well as a reading comprehension test. In order to measure incidental vocabulary learning, subjects were not told that they
were going to be given vocabulary tests. Results showed that the groups that had access to definitions along with both types
of visuals had significantly higher vocabulary scores on both immediate and delayed post-tests than the definition only group.
However, no differences were observed on the reading comprehension test. Finally, the qualitative data revealed that hypermedia
reading had positive impact on participants’ attitudes towards foreign language reading and vocabulary learning.

Global comparisons of learning from hypertext/hypermedia and traditional presentation formats like text have yet failed to
show major advantages concerning the effectiveness of hypermedia learning. Thus, it is proposed in the current paper to evaluate
hypermedia environments more specifically with regard to their potential to implement and support well-defined learning approaches.
According to this view, an effective hypermedia design needs to be based on thorough cognitive task analyses with regard to
structures, processes, and resources that are required to benefit from a specific learning approach. This claim is illustrated
by two experiments in which we explored the instructional potential of hypermedia environments for improving schema acquisition
from worked-out examples. A cognitive task analysis was used to identify specific types of information comparisons that are
crucial for successful schema induction and that might be effectively supported by suitably designed hypermedia environments.
The experiments investigated two methods for enhancing comparison processes in hypermedia-assisted learning from worked-out
examples, namely, elaboration prompts and an interactive comparison tool. Both methods improved performance for near-transfer
problems. Ways of extending this task-analytical approach to facilitating far transfer are also discussed.

Think-aloud and pre-test data were collected from 49 undergraduates with varying levels of prior domain knowledge to examine the relationship between prior domain knowledge and self-regulated learning with hypermedia. During the experimental session, each participant individually completed a pretest on the circulatory system, and then one 40-min hypermedia learning task during which he or she learned about the circulatory system. Think-aloud data were collected during the 40-min learning task to measure each participant’s use of specific self-regulated learning processes related to planning, monitoring, and strategy use. Results indicate that prior domain knowledge is significantly related to how the participants self-regulated their learning during the 40-min learning task with hypermedia. Specifically, prior domain knowledge is positively related to participants’ monitoring and planning and negatively related to their use of strategies during the hypermedia learning task. 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.

A number of available resources offer guidance about hypermedia design strategies, many of which rely on principles of user-centered
design. Many recent efforts, however, have focused more on developing learner-centered hypermedia. Learner-centered hypermedia is designed to help learners achieve their educational goals, rather than offer mere
usability. Unfortunately, this endeavor is hamstrung by a lack of empirical research on the topic. Research conducted in my
laboratory and others has provided some insight, however. It is now understood that several system and user characteristics
influence outcomes of hypermedia-assisted learning (HAL). Among the most relevant factors are learners’ levels of metacognition
and prior knowledge, and the interaction between these factors and hypermedia structure. By capitalizing on this research,
it is possible to create hypermedia that scaffolds learners in their quest to build knowledge and understanding. The present
article draws from empirical findings to suggest hypermedia design strategies aimed at scaffolding learners engaged in HAL.
These guidelines target learners’ knowledge and metacognitive ability to structure hypermedia that maximizes learning potential.

This paper focuses on theory and research issues associated with the use of hypermedia technologies in education. It is proposed
that viewing hypermedia technologies as an enabling infrastructure for tools to support learning—in particular learning in
problem-based pedagogical environments involving cases—has particular promise. After considering research issues with problem-based
learning related to knowledge transfer and conceptual change, a design framework is discussed for a hypermedia system with
scaffolding features intended to support and enhance problem-based learning with cases. Preliminary results are reported of
research involving a new version of this hypermedia design approach with special ontological scaffolding to explore conceptual
change and far knowledge transfer issues related to learning advanced scientific knowledge involving complex systems as well
as the use of the system in a graduate seminar class. Overall, it is hoped that this program of research will stimulate further
work on learning and cognitive sciences theoretical and research issues, on the characteristics of design features for robust
and educationally powerful hypermedia systems, on ways that hypermedia systems might be used to support innovative pedagogical
approaches being used in the schools, and on how particular designs for learning technologies might foster learning of conceptually
difficult knowledge and skills that are increasingly necessary in the 21st century.

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

In this study, we examined the effectiveness of instructional materials designed to control redundancy and split attention
in the teaching of complex orthopedic physical therapy skills. Participants included 41 first-year physical therapy students.
The modified instruction group received a modified unit of instruction designed to reduce cognitive load, while the control
group received a traditionally designed unit of instruction. Four hypotheses were tested relating to achievement on cognitive
and psychomotor tests, ratings of cognitive load, and task completion times. The multivariate analysis yielded significant
results for three of the four hypotheses (ES = +0.52). As predicted, the participants receiving the modified instructional
materials scored significantly higher on the written post-test and psychomotor tasks, while reporting a lower level of cognitive
load on both tasks. These results suggest that designers can increase the germane cognitive load by reducing the extraneous
cognitive load through good instructional and message design practices.

This study investigated the effects of collaboration mode and group composition during a computer-mediated collaborative (CMC)
program. Six intact sections of a computer literacy course were assigned to either a face-to-face or a virtual, online collaboration
treatment condition. Groups consisted of homogeneous lower-ability, homogeneous higher-ability, or heterogeneous-ability pairs.
The study examined the effects of collaboration mode and group composition on individual posttest performance, group project
performance, collaborative interaction behavior, and attitudes towards the instruction. Results indicated that virtual dyads
exhibited significantly more questioning behaviors and significantly better project performance than those who collaborated
face-to-face. By comparison, students in the face-to-face condition performed significantly better on the individual posttest
than those in the virtual online condition. Findings suggest that both virtual and face-to-face collaboration can be effective
in achieving learning goals. However, consideration should be given to the collaborative structure of the lesson and the type
of task in the design of CMC environments.

To better inform and improve classroom teaching and learning, now more than ever before, educational researchers need to effectively and efficiently describe essential components of positive learning environments. In this article, we discuss how our research findings about motivation in classrooms have led to a closer examination of emotions. We describe how motivation theories such as Academic Risk Taking, Flow Theory, and Goal Theory have helped us better understand emotions in our classroom research. Our findings suggest that engaging students in learning requires consistently positive emotional experiences, which contribute to a classroom climate that forms the foundation for teacher–student relationships and interactions necessary for motivation to learn. We conclude that we need to integrate emotion, motivation, and cognition theoretically and methodologically to move our research forward. New theories and methods, even new forms of intellectual discourse, are required. Therefore, we end this article by beginning a discussion of new directions for conceptualizing and researching classrooms in ways that will involve examining the emotions of students and teachers.

Troubleshooting skills are integral for the Information Technology professional. In order to address faculty concerns that
students were not effectively learning required troubleshooting skills, a standardized troubleshooting methodology (the DECSAR
Method) was created and integrated into the standard curriculum of a college information technology program. Components of
troubleshooting were measured using a pre-/post-testing approach with the Social Problem Solving Inventory—Revised. Testing
indicated improvement in several areas of troubleshooting reinforced by DECSAR. The context in which the troubleshooting methodology
was applied was associated with post-test change.

The development of two observational tools for assessing metacognition and self-regulated learning in young children 总被引：1，自引：1，他引：0

This paper reports on observational approaches developed within a UK study to the identification and assessment of metacognition
and self-regulation in young children in the 3–5 year age range. It is argued that the development of observational tools,
although containing methodological difficulties, allows us to make more valid assessments of children’s metacognitive and
self-regulatory abilities in this age group. The analysis of 582 metacognitive or self-regulatory videotaped ‘events’ is described,
including the development of a coding framework identifying verbal and non-verbal indicators. The construction of an observational
instrument, the Children’s Independent Learning Development (CHILD 3–5) checklist, is also reported together with evidence
of the reliability with which it can be used by classroom teachers and early indications of its external validity as a measure
of metacognition and self-regulation in young children. Given the educational significance of children’s development of metacognitive
and self-regulatory skills, it is argued that the development of such an instrument is potentially highly beneficial. The
establishment of the metacognitive and self-regulatory capabilities of young children by means of the kinds of observational
tools developed within this study also has clear and significant implications for models and theories of metacognition and
self-regulation. The paper concludes with a discussion of these implications.

This is a report of one case of a design and development research study that aimed to validate an overlay instructional design
model incorporating the theory of multiple intelligences into instructional systems design. After design and expert review
model validation, The Multiple Intelligence (MI) Design Model, used with an Instructional Systems Design (ISD) Model, was
tested for use by four practicing instructional designers. Instruction developed for learners using this model was then evaluated
measuring post-test and attitudinal scores with 102 participants. This report also provides a reflection on the lessons learned
in conducting design and development research on model validation. The procedures and findings have implications for the processes
involved in instructional design model validation through designer use and program implementation.

A study on classroom based training of self-regulated learning was conducted with fourth grade pupils attending German public
schools. The participating classes were assigned randomly to either a training group or a control group. The pupils in the
training group received 5 weeks of training, as depicted by Zimmerman, Bonner, & Kovach (American Educational Research Journal
31:845-862 1996), during normal classroom instruction and homework activities. Training effects were confirmed for various skills associated
with self-regulation, motivation and performance. By reviewing the solution rates to daily assignments with the help of hierarchical
linear models, a linear growth in the solution rates over the course of the 5 weeks was proven, which weakened towards the
end of the training. Significant differences in the growth rates among the students were also confirmed. Skills in time management,
learning goal orientation and self-efficacy that were evidenced by the students prior to the training proved to be able to
explain variances among the growth curves.

This paper reports the findings of an investigation aimed at gaining a clearer understanding of the nature of vocabulary difficulties
associated with dyslexia and associated risk status. Three studies were conducted to examine preschoolers’ access and mastery
of syntactic- and phonological-based processes believed to support word learning. Results are reported for 82 participants
whose (reading) risk status was assessed from a composite of measures known to be related to reading development. As expected,
risk status correlated positively with participants’ ability to recall the phonological form of novel nouns. No relationship
was found between risk status and participants’ use of syntactic form-class cues in interpreting the noun class of novel names
in isolation. However, the ability to use form-class cues was impaired for at-risk participants on a task that required them
to learn both the phonological form and noun class. Findings are discussed in relation to the suggestion that limitations
in processing resources such as working memory rather than in the availability of language structures may be at the root of
the reported poor performance by at-risk children on vocabulary and other linguistic measures.

Socio-emotional orientations and teacher change 总被引：1，自引：0，他引：1

In this article we consider how elementary education students’ views of mathematics changed during their mathematics methods
course. We focus on four female students: two started the course with mainly positive views of mathematics and a task orientation,
two with negative views of the subject and an ego-defensive orientation. The biggest change observed was that the trainees’
views of teaching and learning mathematics became more positive. Moreover, what had been an ego-defensive orientation changed
towards a social-dependence orientation. The crucial facilitators of change seemed to be (1) handling of and reflection on
one’s experiences of learning and teaching mathematics, (2) exploring content with concrete materials, and (3) collaboration
with a partner or working as a tutor of mathematics.

Our 5-year professional development intervention is designed to promote elementary teachers’ knowledge, beliefs, and practices
in teaching science, along with English language and mathematics for English Language Learning (ELL) students in urban schools.
In this study, we used an end-of-year questionnaire as a primary data source to seek teachers’ perspectives on our intervention
during the first year of implementation. Teachers believed that the intervention, including curriculum materials and teacher
workshops, effectively promoted students’ science learning, along with English language development and mathematics learning.
Teachers highlighted strengths and areas needing improvement in the intervention. Teachers’ perspectives have been incorporated
into our on-going intervention efforts and offer insights into features of effective professional development initiatives
in improving science achievement for all students.

This article reports on the development of a methodology that integrates virtual and hands-on inquiry in a freshman introductory
biology course. Using a two time × two order-condition design, an effective combination (blend) of the two environments was
evaluated with 39 freshman biology participants. The quantitative results documented no significant effect of presentation
order but demonstrated a significant effect of the combined learning experience. The qualitative results showed a strong preference
by students for the virtual work preceding the hands-on laboratory. The study provides practitioners an effective alternative
to traditional instructional practices by combining virtual and hands-on inquiry learning.
