Interactions between two pairs of subjects were conducted face‐to‐face and over a two‐way closed‐circuit television medium and were tape recorded. The speech for each subject over each medium was edited to remove silent intervals and the resulting edited speech segments, each about 1 minute in duration, were analyzed by a computer implementation of the cepstrum method of fundamental‐frequency determination. The speech of all four subjects showed a statistically significant rise in fundamental frequency ranging from 3.89% to 7.83% for the closed‐circuit television condition relative to the face‐to‐face condition. This result could imply that two‐way closed‐circuit television is a more tense or stressful medium than face‐to‐face communication. Alternatively, the effect could be explained by such other factors as a rise in speech level caused by a greater perceived distance between the participants in the closed‐circuit television condition.  相似文献

This study investigates the diversity of early prosocial behavior by examining the ability of ninety‐five 2‐ to 4‐year‐olds to provide aid to an adult experimenter displaying instrumental need, emotional distress, and material desire. Children provided appropriate aid in response to each of these cues with high consistency over multiple trials. In contrast to the consistency with which the children provided aid within each task, there were no cross‐task correlations, and the tendency to respond to each of the cues revealed unique developmental trajectories. Taken together, these results provide preliminary support for the importance of examining the cues to which children are responding and of differentiating between varieties of aid when considering the development of prosocial behavior.  相似文献

Live Interactive Television is a popular medium for delivering educational programs to students in remote areas in Australia. The medium uses television to deliver a live one‐way video signal and standard telephony to provide two‐way audio communication between the instructor and students. Much of the potential of this medium is derived from the interactivity that it supports and the ensuing educational advantages to be derived. Because all interactions are ultimately student‐initiated, the medium has a number of unique and characteristic features. This paper describes a study that investigated the form and nature of the interactions evident in LIT programs. The purpose of this investigation was to establish the impact of the interactivity on the form and scope of the instructional sequences used. The study sought to identify different kinds of interactivity employed by instructors and students and to investigate the impact and role of these interactions on the ensuing instructional activities.  相似文献

After nearly 20 years of educational television, it can still be argued that ETV has not yet ‘arrived’ in the sense of being an accepted, taken‐for‐granted teaching tool. Although production standards are high, both technically and educationally, and although applications of television to learning are well established, television has certain limitations and deficiencies as a presentation medium. This paper discusses these shortcomings from the stand‐points of large‐group viewing, in lecture theatres and classrooms, and of individual study, and suggests that technical developments now in sight could overcome the limitations, to allow ETV to become the normal presentation medium in education and training  相似文献

Medical professionals and public consumers expect that new physical therapy graduates possess cognitive, technical, and behavioral skills required to provide safe and high‐quality care to patients. The purpose of this study was to determine if a repertoire of ten professional behaviors assessed at the beginning of doctorate of physical therapy education and before the first significant clinical internship could be enhanced in a semester course in gross human anatomy using individual formative feedback. During the human anatomy course, 28 first‐year physical therapy students completed six biweekly, anonymous self‐ and peer assessment surveys that targeted ten professional behaviors important to physical therapists. All professional behaviors were assessed using a five‐point Likert scale. Feedback reports occurred at week eight (mid‐semester) and week 16 (end‐of‐semester) and comprised the direct intervention components of this study. At the midpoint of the semester, professional behavior scores and narrative comments from weeks two, four, and six were compiled and shared with each student by one of three faculty members in a feedback session. Students then submitted biweekly self‐and peer professional behavior assessments (weeks 10, 12, and 14) for the remainder of the human anatomy course. Differences between preintervention and postintervention scores for each of the ten professional behaviors were compared using the Wilcoxon signed‐ranks test. Upon receiving mid‐semester individual feedback, students demonstrated significant improvement in each of the ten professional behaviors. Results from this study indicated a gross anatomy laboratory dissection experience during the first academic semester provided an effective opportunity for teaching and assessing professional behaviors of doctoral students in physical therapy.

Twelfth‐grade physics classes with 344 students participated in a quasi‐experimental study comparing two small‐group learning settings. In the jigsaw classroom, in contrast to the cyclical rotation method, teaching expectancy as well as resource interdependence is established. The study is based on the self‐determination theory of motivation, which states that the satisfaction of the ‘basic needs’ for experiencing autonomy, competence, and social relatedness is essential to promote intrinsic motivation. Regarding the experience of competence, a small effect in favour of the jigsaw classroom was found, whereas students in the cyclical rotation setting showed medium‐sized benefits in experiencing autonomy. A path analysis revealed that these opposing effects balanced each other; that is, no effect from small‐group method to intrinsic motivation was found. In contrary to the motivational variables, achievement effects depended on the underlying study topic: based on scanning electron microscopy, the cyclical rotation setting outperformed jigsaw classroom, whereas an opposed trend is observed with regard to the microwave oven learning unit. The higher interestingness of the latter learning unit was revealed as a weak mediator from study topic to academic achievement.  相似文献

It has been suggested that improvements in the quality of distance‐teaching materials could be effected if the mental responses that mediate study of and learning from such materials were known. This project aimed at identifying the types and origins of students’ convert mediating responses to distance‐teaching materials during study sessions. Three one‐half hour study sessions were videotaped for each of four student volunteers in a room set up on the campus. Immediately following each study session stimulated‐recall interviews were conducted, the data from these being audiotaped and then transcribed for further analysis. Interview protocols revealed that approaches to study were influenced by a set of interdependent factors, which, when combined with a set of study strategies, resulted in two broad classes of study orientation. Twenty different types of mental processes were identified, seven of which were used more frequently than the others. Furthermore, textual features which activated mental processes were identified using the stimulated‐recall technique, and promising suggestions for textual design were gleaned from the data. Areas for further research were also identified.  相似文献

Every year, many students in the UK fail to achieve a place at their preferred university because they take the wrong A‐level subjects. This study aims to suggest a framework for helping students choose the right subjects. Data on student achievement in A‐level examinations were obtained from a UK sixth form college over a four‐year period. Statistical techniques were employed to support our hypothesis that a student’s choice of A‐level subjects should be based on both the student’s ability and a university’s preference for particular subjects and grades. Despite the limitation of small sample size, a model has been created that will maximise a student’s chance of achieving a place at his/her university of choice. The model presented could easily be extended in future to incorporate more levels in each of the attributes considered, and in this way it could provide the optimal choice of subjects for each individual student given his/her particular aspirations.  相似文献

This paper describes the process employed by a psychological service to gather the views of children and young people using guided discussion groups and questionnaires. Pupils in the guided discussion groups were asked to identify issues that affect them and how adults could help. This information was analysed using thematic analysis. Seven themes were identified as issues: managing feelings; friendships; behaviour; specific difficulties that can affect learning; not being accepted; bullying; and ‘other important issues’, including bereavement and family difficulties. In relation to each of these themed issues, several sub‐themes regarding how adults could help were collated. Questionnaire data was analysed using inferential statistics. The questionnaire rated the importance of help from adults in the areas of learning, friendships and feelings. Results suggested that these were equally important to primary‐aged pupils. Findings were used to contribute to the development plan and shape future practice.  相似文献

Children with motor difficulties are a very varied group. In order to target interventions more effectively researchers have attempted to identify specific sub‐groups; however, attempts to identify sub‐groups and provide interventions accordingly have met with limited success. Currently interventions can be classified into two main types, namely, general abilities and normative functional approaches. The current study outlines the Manchester Motor Skills Programme (MMSP), which adopts a normative functional approach and has been developed jointly by educational psychologists (EPs), specialist teachers and schools. In order to evaluate the effectiveness of the MMSP a quasi‐experimental repeated measures study was undertaken involving 24 children. The quasi‐experimental study yielded a medium effect size, which is a promising result for a naturalistic intervention. Methodological limitations and areas of future research are considered and identified.  相似文献

Abstract

The purpose of the study was to examine the engagement of preservice teachers in the kind of authentic experiences that provided the modeling needed to make high‐quality instruction in mathematics a reality for young children. Inasmuch as these preservice teachers had not yet received any formal methods classes in mathematics, the authors theorized that classroom teachers whose practices and dispositions were congruent with the National Council of Teachers of Mathematics standards and the State of South Carolina Mathematics Standards could model effective teaching instruction for young children using the project approach. These same teachers could then provide mentoring and encouragement to preservice teachers as they became involved in this high‐quality program for 4‐year olds, deepening the knowledge base of the preservice teachers regarding developmentally appropriate ways to teach numeracy to 4‐year olds. © 2005 Elsevier Inc.

Prompting systems are guidelines of when to provide learners with prompts and when to fade prompts. Today, there are several prompting systems implemented to teach receptive labeling to individuals diagnosed with autism spectrum disorders and other disabilities. This study compared most‐to‐least prompting to an error correction procedure involving feedback and remedial trials for teaching two children with autism a variety of receptive labels. All teaching was implemented in a one‐to‐one instructional setting. Researchers taught each participant how to receptively identify 18 pictures; nine were taught using error correction and nine were taught using most‐to‐least. The researchers utilized an adapted alternating treatment design nested into a multiple probe design to evaluate the two procedures. Results indicated that participants were able to reach mastery criterion on 100% of skills taught using the error correction and were able to reach mastery criterion on 88.9% of skills taught using most‐to‐least. Additionally, error correction tended to require fewer trials for participants to reach mastery criterion.  相似文献

There is a trend in Irish universities to utilise the benefits of the e‐learning as a mechanism to improve learning performance of campus‐based students. Whilst traditional methods, such as face‐to‐face lectures, tutorials, and mentoring, remain dominant in the educational sector, universities are investing heavily in learning technologies, to facilitate improvements with respect to the quality of learning. The technology to support reuse and sharing of educational resources, or learning objects, is becoming more stable, with interoperability standards maturing. However, debate has raged about what constitutes effective use of learning technology. This research expands upon a study carried out in 2003 examining students’ perceptions of e‐learning in a large undergraduate accounting class environment. As a result, improvements were made to the instructional design of the course, to enable students to engage interactively with content. The subsequent study, reported in this paper, adopted a broad range of techniques to understand students’ learning experience in depth. The findings of this research provide an insight into how these students really work and learn using technologies, if at all. It is hoped that our findings will improve the experience for both students and lecturers who engage in teaching and learning through this medium.  相似文献

The purpose of this study was to investigate how concept cartoons, together with other diagnostic and scaffolding tools, could be used in formative assessment, to stimulate talk and argumentation among students in small groups, as part of peer‐assessment and self‐assessment; and to provide diagnostic feedback about students’ misconceptions to the teacher for teaching towards conceptual change. Two classes of Primary 5 and 6 students worked in small groups to discuss the opposing viewpoints posed by the cartoon characters, using scaffolding tools to guide their discussions and to evaluate, challenge, and document each others’ ideas. Students also used drawings to depict their ideas. The conversation from one group was audio‐taped. These tools provided a record of students’ thinking in a form that was accessible to the teacher for monitoring and feedback purposes. Findings showed dialogic talk and interactive argumentation among students where they made their reasoning visible. Students’ assertions and questions had formative potential as they encouraged exploratory and reflective discourse by drawing upon each others’ ideas. The teacher’s discursive practices, as well as her role in designing scaffolding structures for supporting ‘assessment conversations’ when using concept cartoons and in devising strategies that take into account students’ conceptual and epistemic thinking, are emphasised.  相似文献

Young children have better math abilities when their parents engage in more math‐related conversations with them. Yet, previous studies have found that math talk occurs only very infrequently in everyday interactions. In the present study, we sought to promote adult–child conversations about math in a naturalistic context using minimal instructions. We observed 179 adult–child dyads while they shopped in grocery stores with signs prompting them to engage in math‐related conversations (math condition), signs prompting them to talk about other topics (general language condition), or without any signs (baseline condition). In the math condition, more adults talked about math compared to the general language or the baseline condition, and this finding could not be explained by demographic characteristics of the dyad or the overall amount of conversations. This study demonstrates that cost‐effective signs placed in everyday contexts can promote math‐related conversations and potentially provide math learning opportunities for children.  相似文献

This paper attempts to trace the dynamic processes involved in the establishment and maintenance of teacher‐pupil relationships and to explore some of the frameworks to be found at the level of face‐to‐face interaction. The article draws upon a qualitative study of one‐to‐one adult literacy tuition (Braund, 1981), which utilises the perspectives, experiences and definitions of grass‐roots participants to provide illumination and insight into an essentially ‘closed’ world. To these everyday interpretations, concepts from social phenomenology and symbolic interactionism are applied. The study reveals the stage by stage evolution of tutor‐student relationships during which individual interpretations and definitions of the situation are combined through negotiation to form a tailor‐made working concensus within each dyad. It goes on to show how the seeds of change contained within each relationship cause it to be in a state of constant evolution leading ultimately to its metamorphosis or termination. This emerging pattern, or relationship ‘career’, provides a framework to an apparently unstructured situation and it is the analysis of this process which forms the basis of the paper.  相似文献

Absctract. This article describes a two‐year study addressing the effectiveness of a highly structured, systematic tutoring intervention implemented by minimally trained college students with two cohorts of at‐risk first‐grade readers. Participants were 61 first‐grade children in Cohort 1 and 76 first‐grade children in Cohort 2. Tutors participated in three one‐hour training sessions and received occasional on‐site assistance. Individual tutoring sessions were scheduled for three to four times each week for one school year, with each cohort receiving approximately 10–14 hours of instruction across 44 sessions. The curriculum included a game to teach phonemic awareness and letter‐sound correspondence, structured word‐study activities, reading of leveled books, and simple comprehension strategies. Significant differences were found on measures of phonemic awareness and nonsense word reading for both cohorts. For Cohort 1, but not Cohort 2, significant differences were also detected for real‐word identification. Our results support using tutors to provide additional assistance and instruction in early reading, even when tutors are not professionally trained teachers.  相似文献

The applications of item response theory (IRT) models assume local item independence and that examinees are independent of each other. When a representative sample for psychometric analysis is selected using a cluster sampling method in a testlet‐based assessment, both local item dependence and local person dependence are likely to be induced. This study proposed a four‐level IRT model to simultaneously account for dual local dependence due to item clustering and person clustering. Model parameter estimation was explored using the Markov Chain Monte Carlo method. Model parameter recovery was evaluated in a simulation study in comparison with three other related models: the Rasch model, the Rasch testlet model, and the three‐level Rasch model for person clustering. In general, the proposed model recovered the item difficulty and person ability parameters with the least total error. The bias in both item and person parameter estimation was not affected but the standard error (SE) was affected. In some simulation conditions, the difference in classification accuracy between models could go up to 11%. The illustration using the real data generally supported model performance observed in the simulation study.  相似文献

The objective of this study was to investigate the effects of three different screen sizes (small, medium and large) and two types of multimedia instruction (text only and text with pictorial annotation) on vocabulary learning. One hundred thirty‐five Korean middle school students learning English as a foreign language were randomly distributed into six groups and were given a pretest, a self‐study multimedia instruction, a posttest and a retention test online. The pretest, posttest and retention test were identical and included 30 vocabulary questions. Results show that the large screen multimedia instruction helped the students to learn English vocabulary more effectively than the small screen instruction as demonstrated on both the posttest and retention test. However, there was little difference in vocabulary learning between the text‐only and text‐with‐pictorial annotation instructions. Although visual perception can be influenced by each learner's expectations and knowledge, using a smaller screen for instruction causes more challenges for learners to perceive and comprehend vocabulary learning.  相似文献
