An experimental comparison was made of the effects of teacher participation, teacher probing behavior, and nonparticipation by teachers during the sociodramatic play sessions of three groups of Head Start preschool students (twelve subjects). A combination of the multiple baseline and multielement single-subject designs was employed to study the effects of teacher participation in sociodramatic play on the amount of language production exhibited by Head Start students. A Placheck method was utilized to record student language production at the end of each 10-second interval throughout each 10-minute session. Thirty play sessions were observed and recorded by both the researcher and a videocamera. Students were selected by their teachers, and all play sessions took place within the children's own classroom. Subjects included six males and six females.The study was divided into three phases. The Baseline phase included the alternation of the conditions of teacher participation and nonparticipation. At the end of this phase, teachers were trained in the use of probes, or questions to which the answer is not known by the teacher. During the Probe phase, teachers participated in play sessions daily and utilized frequent probes. During the Multielement Manipulation phase, the conditions of teacher participation alone and teacher participation emphasizing the use of probes were randomly alternated. Graphic representations of subject performance data were used to portray intersubject and intrasubject variability.Results indicated that rates of student language production increased for 10 out of 12 students (83%) when exposed to the condition of teacher probing during the Probe phase of the study. When the effects of teacher participation and teacher participation emphasizing probing were compared, it was found that 11 out of 12 students (92%) exhibited higher rates of language production during the condition of teacher probing.It was concluded that the use of teacher participation in the sociodramatic play of Head Start students, particularly with an emphasis on probing behavior, proved to be most beneficial in enhancing the amount of language production of the students. The findings of the present study lend support to the concept that teacher participation in the sociodramatic play of low-income preschool children can result in increased student language development.

This scale uses one or two word descriptors for hearing level categories and is based on a pure tone average (PTA), the average of hearing thresholds at 500, 1000, and 2000 Hz. Although these categories were developed from clinical and educational observations (Goodman, 1965), degree of hearing loss has not been shown to reliably predict the educational or language performance of children with hearing impairment (Martin & Clark, 1996). This study was designed to evaluate how the presentation modality (hearing loss simulation vs. using a term to describe the hearing loss using the Goodman scale) affects predictions of children&softsign;s communication difficulties in the classroom by graduate speech-language pathology students. / ABSTRACT: The perceptions of graduate speech-language pathology students were of interest because this population had not been included in earlier investigations, despite the fact that they often work with hearing-impaired children in the school systems. Three levels of hearing loss (mild, moderate, and severe) were introduced using two different presentation conditions. In one condition, a descriptive term from the Goodman scale was used to describe the hearing loss. In the other presentation conditions, a simulated hearing loss was presented to the participants. Following each presentation of each hearing loss, the participants rated the potential communication difficulty a child with that loss may have in the classroom using a questionnaire composed of nine different communication-related tasks (Appendix A). / ABSTRACT: In general, participants predicted significantly greater difficulty when presented with the simulated hearing loss, than when presented with the descriptive term for the same degree of hearing loss with a few exceptions. The results of this study indicated that the standard method of classifying hearing loss results in underestimation of the impact a hearing loss might have for a child. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.

The purpose of the investigation was to examine the effect of training on the use of morphology and syntax of language delayed children. Performance with no instruction was compared to performance with two methods: (1) a Standard Remedial Instruction Approach and (2) the Individualized Instruction Approach. The intent was to determine if a standard method would be superior to no instruction; and then, if individualization of training procedures, based on a functional analysis of the child's approach to learning tasks, would facilitate progress over what might be achieved with the standard method. Finally, a follow-up test was done to check if skills were maintained. Three language delayed children in a Primary Resource Classroom served as the subjects. A multiple baseline across subjects design was employed, with a sequential multiple intervention component added. Using each subject as his own control, his performance was compared across adjacent phases. Instructional phases were introduced to subjects in a staggered fashion rather than at the same time to test the power of each intervention. The method chosen as the Standard Remedial Instruction approach was the Interactive Language Development Teaching method. The Individualized Instruction approach was devised from a functional analysis. Diagnostic teaching provided the means for doing the functional analysis, during which the child's responsiveness to varied stimulus, response, affective and cognitive dimensions of tasks was observed. Performance under the different phases of the study was measured by experimenter-made criterion referenced tests on the specific language forms being taught. Each test required a degree of generalization since novel stimulus materials were used. Visual analysis of the data was facilitated by use of trend lines made by the method of least squares, to determine changes between phases. Trend lines of adjacent phases were compared in terms of level and slope. The procedures described above yielded the following results: (1) All three subjects showed notable improvement in performance with Standard Remedial Instruction as compared to Baseline performance; (2) All three subjects displayed some improvement with Individualized Instruction over Standard Remedial Instruction, but by trend analysis, only one exhibited marked improvement; and (3) The performance of two subjects on follow-up testing was commensurate with the level of performance obtained during Individualized Instruction. The findings of the study indicate that, within the context of the public schools, improvement in morphology and syntax of language delayed children is dependent upon the use of systematic language instruction. Provision of such instruction, and the establishment of more efficient screening procedures for identifying expressive syntax problems, therefore seem warranted. If a standard remedial instruction program does not seem to be effective, an individualized program may be needed. A functional analysis of the child's learning characteristics appears to provide a sound basis from which to develop an individualized program. Speech and language clinicians, thereby, could increase their effectiveness by learning to conduct a functional analysis. The study further documents the promise of time-series research for use with a handicapped population. A public school system could use such a design to evaluate methods or programs. It would be relatively easy and inexpensive to conduct. A limitation of the particular design used for this study was that the effect of method two could not be separated from the effect of method one since it was always preceded by method one. An alternation of methods could alleviate the problem. A study of this type has minimal significance by itself but in a series can make a contribution.
