Market segmentation for improved distance education program planning     

Michele D. Bunn  Robert E. Barnes 《Distance Education》1999,20(2):274-294

Distance education planners face two basic, yet difficult decisions: which students should be targeted and which programs should be offered? This paper reports the process and results of the planning committee of a consortium of engineering schools in the United States that was tasked with these very decisions. A market research study measured the program preferences of potential students. Three program characteristics (course type, delivery method, and time availability) were examined. The results show there is no ‘average’ student and no single program will satisfy all the needs of the student population. Rather, the committee must choose one or more segments based on the program preferences of the students and the resources required to provide the programs.  相似文献   

Orthographic analogies and early reading: Explorations of performance and variation in two transfer tasks     

Savage  Robert  Stuart  Morag 《Reading and writing》2001,14(7-8):571-598

Two experiments investigated the use of orthographic analogies in 6 year olds. In Experiment 1, 26 children were shown CVC clue and target word pairs sharing either rimes (`fork' – `pork'), heads (`fork' – `ford') or were controls (`fork' – `hurl'). A modest advantage for rime-clued over head-cluedtargets was unreliable over by-subject and by-item analyses. Improvements in target word reading were correlated with pretest scaffolding errors (e.g. `pork' misread as `park'). In Experiment 2, 50 children were pretaught three clue words for each target word before being shown words that shared either rimes (`leak' – `peak'), or medial vowel digraphs (`leak') – `bean'), or were controls (`leak' – `herd'). A modest advantage for rime-clued over vowel digraph-clued targets was again unreliable over by-subject and by-item analyses. Neither rime nor phoneme awareness measures were correlated with rime inference use. Vowel, but not rime inference, was correlated with scaffolding errors. Rime detection was the strongest predictor of reading ability, whereas phoneme segmentation was the strongest predictor of the use of scaffolding errors.  相似文献   

Matching Cloze as an Evaluation Procedure for Slow Learning Children     

Richard B. Baldauf Jr.  Robert Morley 《International Journal of Disability, Development & Education》1979,26(1):23-26

The matching cloze procedure, which does not require language production skills and which is simple enough for the classroom teacher to construct unaided, was originally developed to measure reading skills of elementary English‐second‐language pupils. The results of this pilot study with opportunity school children indicate the validity of the procedure as an evaluation technique for slow learning children.  相似文献

The etiology of mathematical self-evaluation and mathematics achievement: understanding the relationship using a cross-lagged twin study from age 9 to 12     

Luo YL  Kovas Y  Haworth CM  Plomin R 《Learning and individual differences》2011,21(6):710-718

The genetic and environmental origins of individual differences in mathematical self-evaluation over time and its association with later mathematics achievement were investigated in a UK sample of 2138 twin pairs at ages 9 and 12. Self-evaluation indexed how good children think they are at mathematical activities and how much they like those activities. Mathematics achievement was assessed by teachers based on UK National Curriculum standards. At both ages self-evaluation was approximately 40% heritable, with the rest of the variance explained by non-shared environment. The results also suggested moderate reciprocal associations between self-evaluation and mathematics achievement across time, with earlier self-evaluation predicting later performance and earlier performance predicting later self-evaluation. These cross-lagged relationships were genetically rather than environmentally mediated.  相似文献   

Teacher Efficacy Research 1998–2009: Signs of Progress or Unfulfilled Promise?     

Robert M. Klassen  Virginia M. C. Tze  Shea M. Betts  Kelly A. Gordon 《Educational Psychology Review》2011,23(1):21-43

This review investigates the state of teacher self- and collective efficacy research conducted from 1998 to 2009. Two hundred and eighteen empirical articles published in 1998–2009 were examined for key characteristics and compared to research published in the previous 12 years (i.e., 1986–1997). Results from the review show increases in overall teacher efficacy research, methodological diversity, domain specificity, internationalization, and focus on collective efficacy. Continuing problem areas were a lack of attention to the sources of teacher efficacy, continued measurement and conceptual problems, a lack of evidence for the links between teacher efficacy and student outcomes, and uncertain relevance of teacher efficacy research to educational practice. An outline of directions for future teacher efficacy research is provided.  相似文献   

Effect of postsecondary education on the economic status of persons who are deaf or hard of hearing     

Schley S  Walter GG  Weathers RR  Hemmeter J  Hennessey JC  Burkhauser RV 《Journal of deaf studies and deaf education》2011,16(4):524-536

This article examines the effect that postsecondary education has on earnings and the duration of time spent in the Social Security disability programs for young persons who are deaf or hard of hearing. Our hypothesis is that investments in postsecondary training increase the likelihood of employment for persons who are deaf or hard of hearing and thus reduce dependency on disability-related income support programs. A longitudinal data set based upon records from the National Technical Institute for the Deaf and Social Security administrative records is used for this analysis. We find that those who graduate, even those who graduate with vocational degrees, experience significant earnings benefits and reductions in the duration of time spent on federal disability programs when compared with those who do not graduate with a degree. This finding suggests that reductions in the duration of time spent on Social Security programs are not limited to those with the highest level of scholastic aptitude and that investments in post-secondary education can benefit a broad group of deaf and hard-of-hearing persons. In addition, the data show that individuals who attend college, but withdraw before graduation, fair no better economically than individuals who never attended college.  相似文献   

Concept learning by pigeons: Matching-to-sample with trial-unique video picture stimuli     

Anthony A. Wright  Robert G. Cook  Jacquelyne J. Rivera  Stephen F. Sands  Juan D. Delius 《Learning & behavior》1988,16(4):436-444

Pigeons were trained to match-to-sample with several new methodologies: a large number of stimuli, computer-drawn color picture stimuli, responses monitored by a computer touch screen, stimuli presented horizontally from the floor, and grain reinforcement delivered onto the picture stimuli. Following acquisition, matching-to-sample concept learning was assessed by transfer to novel stimuli on the first exposure to pairs of novel stimuli. One group (trial-unique), trained with 152 different pictures presented once daily, showed excellent transfer (80% correct). Transfer and baseline performances were equivalent, indicating that the matching-to-sample concept had been learned. A second group (2-stimulus), trained with only two different pictures, showed no evidence of transfer. These results are discussed in terms of the effect of numbers of exemplars on previous failures to find concept learning in pigeons, and the implications of the positive finding from this experiment on abstract concept learning and evolutionary cognitive development.  相似文献   

Perseveration of associative strength in rabbit nictitating membrane response conditioning following ISI shifts     

Robert T. Ross  Michael J. Scavio 《Learning & behavior》1983,11(4):435-438

The present experiment determined whether associative strength based upon 15 CS-US pairings at various interstimulus intervals (ISIs) could survive shifts of the ISI to influence the subsequent acquisition of the nictitating membrane (NM) CR. The choice of 15 preshift pairings was based upon previous work, which had shown that this training level produced substantial associative strength without NM CR acquisition. Consequently, this experiment, by shifting the ISI before the beginning of CR acquisition, served as an extension to traditional ISI-shift studies that have imposed the manipulation after CR acquisition. The findings of the experiment indicated that 15 preshift pairings in Stage 1 at ISIs from 250 to 4,000 msec were as effective as 15 pairings at a 500-msec ISI in determining the number of trials to the first NM CR in Stage 2 in which the training ISI was 500 msec. Moreover, 15 pairings in Stage 1 at ISIs from 250 to 2,000 msec were equivalent to 15 pairings at 500 msec in controlling the number of trials to 10 successive NM CRs in Stage 2. These outcomes demonstrate that, within a large ISI range, the associative strength based upon relatively few pairings is preserved despite various shifts of the ISI. Therefore, these results suggest that the reductions in CR performance, which have been consistently observed in traditional studies following ISI shifts, are not due to the loss of associative strength.  相似文献
