A microcomputer/mini-floppy disk system is used by students in the laboratory portion of an introductory physics course for science majors. Its purposes are to store their experimental data, do data analyses, and exchange messages with the lab instructor. The system also provides computer-assisted instruction (CAI) simulations of certain lab experiments, and interfaces with measuring equipment in certain experiments. Each student has a personal diskette for data files and basic utility programs for an entire semester. The ease of disk data manipulation under program control is exploited in the following ways: (i) a wide variety of data reduction techniques are introduced that permit quantitative comparisons between experimental results and theoretical expectations; (ii) facile data reduction and analyses permit preliminary processing of experimental data during the course of the lab period, so that decisions can be made by students concerning the course of the remainder of the experiment; (iii) accumulated data from various experiments become a course database permitting subsequent analyses of old data adapted in several different logical ways (e.g., RC curcuit data first treated as energy storage, later as one of a number of exponential relationships); (iv) comprehensive course database formed by merging regarding the reliability of experiments. These considerations favor laboratory goals different from the demonstration and confirmation of given physical laws. Specifically they inculcate critical thinking and hypothetico-deductive reasoning. I discuss several very real problem areas that plagued this novice and compromised implementation. I compare these problems with the qualitative improvements in laboratory learning. © 1982, American Association of Physics Teachers. All rights reserved.

An electronic device capable of monitoring the rate at which voice intensity increases during voice onset provides an indicator of the abruptness of phonatory initiation. Two groups of 8 subjects were taught to reduce the abruptness of glottal attack. Group A used a seven step program employing the electronic monitor while Group B used the same seven step program but with a traditional approach to the reduction of abrupt glottal attack substituted for monitor use. Both groups used a self-instruct teaching paradigm. Subject recordings of pre and post program production of five voice onset moments were submitted to sonographic amplitude analysis and a time/intensity slope ratio was calculated for each. Further, the pre and post program recordings were judged for abruptness of glottal attack. Post program slope ratios and attack judgments were significantly different (p < 0.01) from pre program data for Group A only. These data suggest that electronic monitoring was effective in producing gradual phonatory initiation.

This investigation examined the prevalence and nature of grief in response to patient suffering, loss, or death among healthcare workers employed at a general hospital and a skilled nursing facility. A questionnaire was constructed for this purpose. Approximately two-thirds of the skilled nursing facility personnel remembered experiencing bereavement as a reaction to the crises of their geriatric patients. Mourning occurred among virtually all of the general hospital personnel who usually serve younger patients. Healthcare personnel mourned most often for those persons who suffered or died of cancer. A selected sample of respondents recalled that psychological symptoms of grief were more evident than physical. Both symptom types often persisted for more than 1 month. Since grief is common among nurses and aides employed at the two medical settings, bereavement counseling is suggested for those healthcare personnel who require this service.
