Speaking personally—with Barbara A. White     

Connie L. Dillon 《The American journal of distance education》2013,27(2):73-79

This study examined the influence of group structures upon six groups of distributed graduate students as they pursued a six-week problem-based learning activity by communicating in an asynchronous computer conference. Henri and Rigault's (1996) content analysis framework and Howell-Richardson and Mellar's (1996) guidelines for interconnectedness of messages were used to analyze the messages. In addition, learners' perceptions of interdependence and intersubjectivity were gauged from a self-reported survey developed by the researcher. Overall comparisons revealed that group conferences with role assignment had higher levels of interconnected messages. Weekly comparisons also indicated higher perceptions of intersubjectivity and deep processing for the role assignment group during the initial weeks of the activity. Over time, however, these levels equalized across group structures.  相似文献   

Nonword repetition with spectrally reduced speech: some developmental and clinical findings from pediatric cochlear implantation     

Burkholder-Juhasz RA  Levi SV  Dillon CM  Pisoni DB 《Journal of deaf studies and deaf education》2007,12(4):472-485

Nonword repetition skills were examined in 24 pediatric cochlear implant (CI) users and 18 normal-hearing (NH) adult listeners listening through a CI simulator. Two separate groups of NH adult listeners assigned accuracy ratings to the nonword responses of the pediatric CI users and the NH adult speakers. Overall, the nonword repetitions of children using CIs were rated as more accurate than the nonword repetitions of the adults. The nonword repetition accuracy ratings from both groups of subjects were correlated with open- and closed-set word recognition scores and forward digit spans. Only the perceptual accuracy scores from pediatric CI users were correlated with measures of speech production accuracy. These results suggest that although the pediatric CI users had more experience and success in perceiving speech under degraded auditory conditions, developmental differences in their memory skills prevent them from performing as well on working memory tasks as mature listeners.  相似文献

Thesaurus-based automatic book indexing     

Martin Dillon 《Information processing & management》1982,18(4):167-178

This paper describes a technique for automatic book indexing. The technique requires a dictionary of terms that are to appear in the index, along with all text strings that count as instances of the term. It also requires that the text be in a form suitable for processing by a text formatter. A program searches the text for each occurrence of a term or its associated strings and creates an entry to the index when either is found. The results of the experimental application to a portion of a book text are presented, including measures of precision and recall, with precision giving the ratio of terms correctly assigned in the automatic process to the total assigned, and recall giving the ratio of correct terms automatically assigned to the total number of term assignments according to a human standard. Results indicate that the technique can be applied successfully, especially for texts that employ a technical vocabulary and where there is a premium on indexing exhaustivity.  相似文献   

The effect of practical work on students' understanding of combustion     

Rod Watson  Teresa Prieto  Justin S. Dillon 《科学教学研究杂志》1995,32(5):487-502

This paper describes a study which investigated 14 and 15 year old students' understanding of combustion in both England and Spain, and explores the effect of practical laboratory experience on students' understanding. The teaching and learning styles used with the students in the study were explored using questionnaires and interviews. The students' understanding of combustion was explored using a questionnaire. The responses of English and Spanish students are significantly different. The quality of the responses is explored in terms of the awareness of students of the involvement of gases in combustion, and it appears, however, that the more extensive use of practical work in English schools has had only a marginal effect on their understanding of combustion.  相似文献   

Financial aid and student persistence in online education in the United States     

Adnan Qayyum  Sarah Zipf  Ramazan Gungor  Janet May Dillon 《Distance Education》2019,40(1):20-31

Distance education has historically had lower completion rates. Several models of persistence, for on-campus students, indicate that students’ financial status affects their decision to persist. This study involved providing distance education students’ financial aid in the form of institutional scholarships (N = 545) at Penn State University in the United States. The recipients were students who were not overachievers and not at-risk of failing, but somewhere in the middle. The purpose of the study was to test if receiving financial aid was related to students’ persistence. Using logistic regression and Chi-square analysis, this study found that scholarship-receiving students with higher financial need were two times more likely to persist in their studies than those with lower financial need. Results suggest that there is a positive relationship between providing even small financial aid to students with high-financial need and their persistence in their studies.  相似文献   

NARST: a lived history

In this Forum, we construct a history of the National Association for Research in Science Education (NARST) through the analysis of documents and through the personal perspectives of individuals. The history of NARST is inseparable from the biography of the individuals through whose lives it was produced and reproduced. The history of NARST is a living history that both shapes and was shaped by the biographies of its members.

Exploring students’ epistemological knowledge of models and modelling in science: results from a teaching/learning experience on climate change     

Giulia Tasquier  Olivia Levrini  Justin Dillon 《International Journal of Science Education》2016,38(4):539-563

The scientific community has been debating climate change for over two decades. In the light of certain arguments put forward by the aforesaid community, the EU has recommended a set of innovative reforms to science teaching such as incorporating environmental issues into the scientific curriculum, thereby helping to make schools a place of civic education. However, despite these European recommendations, relatively little emphasis is still given to climate change within science curricula. Climate change, although potentially engaging for students, is a complex topic that poses conceptual difficulties and emotional barriers, as well as epistemological challenges. Whilst the conceptual and emotional barriers have already been the object of several studies, students’ reactions to the epistemological issues raised by climate changes have so far been rarely explored in science education research and thus are the main focus of this paper. This paper describes a study concerning the implementation of teaching materials designed to focus on the epistemological role of ‘models and the game of modelling’ in science and particularly when dealing with climate change. The materials were implemented in a course of 15 hours (five 3-hour lessons) for a class of Italian secondary-school students (grade 11; 16–17 years old). The purpose of the study is to investigate students’ reactions to the epistemological dimension of the materials, and to explore if and how the material enabled them to develop their epistemological knowledge on models.  相似文献
