Applied researchers increasingly report the use of paraprofessionals to implement key program components. However, despite such apparent advantages as increased availability and lower salaries, problems in maintaining acceptable levels of on-the-job performance in these workers have been reported. This study assessed the effects of a supervisory package on the work behavior of five paraprofessional tutors in a remedial reading program. The package consisted of written handouts and instructions, tests of tutor understanding, a video tape, mention of tutor performance by supervisors, and publicly posted feedback on work performance. One randomly chosen tutor received feedback each day on (1) his degree of completeness in tutoring one student's answers to comprehension-check questions, (2) his accuracy in tabulating that student's data sheet, and (3) his promptness in beginning the first student's tutorial session. The supervisory package produced marked improvement in completeness, some improvement in accuracy, but no improvement in promptness. Application of the supervisory package seemed practical, as an average of nine daily tutorial sessions (approximately 270 min of tutoring) required a total daily average of only 28 min of supervision. It was concluded that completeness performance by nondegreed, paraprofessional tutors was closely related to the extent to which they were supervised. Despite the fact that no improvement was observed in tutor promptness, and only partial improvement was observed in tutor accuracy, the improvement to near-perfect levels in tutor completeness suggests that further research is warranted to develop supervisory packages that might ensure the reliable and efficient use of paraprofessional workers. 相似文献

The author, a professional flutist and psychologist, interviewed four pianists noted for their sight-reading abilities. The results of the interviews are considered from several points of view. Sight-reading is analyzed as a problem in pattern recognition: a movement from a sonata by Handel is used to illustrate the principle of scanning for familiar patterns. The close relationship between musical sight-reading and the reading of conventional texts is also suggested. Finally, drawing on the findings of other studies, a cognitive model of musical sight-reading is proposed. The schematic model of interlocking information-processing systems explains the differences between skilled and unskilled sight-readers; it also explains why some experienced, professional musicians are poor sight-readers. Verification of the model is provided in an additional section in which conversations with unskilled sight-readers are reported. 相似文献

A wide variety of complex waveforms can be generated by approximating the desired analog waveform from an array of digital values. Some basic properties of these digital approximations are discussed in terms of pulse amplitude modulation and sampling theory. The waveforms are generated by transferring the digital values to a digital-to-analog converter followed by a low-pass filter. This usually requires the dedicated use of a computer. We have built a device, incorporating solid state memory, that can store, time, and transfer previously computed digital values, so that a computer is no longer necessary to generate the waveforms. Specifications of the digital-to-analog converter and appropriate settings of the filter are discussed, along with a simplified procedure for calculating waveforms that have line spectra. An adaptation of this procedure enables the device to be used as a high-speed programmable pure-tone source. 相似文献

This paper reviews recent developments in the area of behavioral marital therapy (BMT). New information is summarized regarding the long-term efficacy of BMT and the identification of predictors of positive response to treatment and to relapse. Finally, new applications of BMT techniques are reviewed (e.g., spouse-involved therapies as the sole treatment for presenting problems in which marital distress is not the primary focus such as anxiety and affective disorders). 相似文献
