An equivalence class exists if the stimuli that comprise the class are related by the properties of reflexivity, symmetry, and transitivity. Through these properties, new behavior that has not been taught emerges. For example, when taught to match Set A stimuli to Set B stimuli and to match Set A stimuli to Set C stimuli, if equivalence classes have formed, subjects will (with no explicit instruction) match Set B stimuli to Set C and Set C stimuli to Set B stimuli. Although equivalence classes have been studied extensively, few studies have considered the application of this technology to educational concerns. The purpose of this study was (a) to determine if phonics skills could effectively and efficiently be taught to young children through the formation of equivalence classes and (b) to investigate the generality of those acquired skills. Using a conditional discrimination procedure, children were taught to match printed letters to dictated phonetic sounds and to match the initial sound of pictured items to dictated phonetic sounds. Test results indicated that equivalence classes had emerged and that generalization did occur. The children could match the initial sound of pictured items to printed letters and vice versa and could name letter sounds and initial sounds of pictured items. During generality testing, each child could identify the initial sound of several novel pictured items and could sound out the letters within the words. However, reading did not occur. Only 1 of 5 children could blend the sounds of letters into recognizable words. A significant difficulty encountered throughout the study was maintaining the children's motivation, possibly due to the children's inexperience in attending to academic tasks. This study did, however, demonstrate that the formation of equivalence classes is an effective and efficient method for teaching phonics and that the formation of generalized equivalence classes is effective in extending those taught relations to novel stimuli. / Department of Special Education

This study investigates the differences in receptive language of kindergarten children who are taught by different language systems. This study compares the effectiveness of the three most widely adopted oral language systems in the state of Texas. The systems used were (A) Alpha Time, (B) Beginning Readiness Kit; Beginning to Read, Write, and Listen Kits I and II, and (c) McMillan Series R, Bank Street, Threshold K. S. Analysis of variance techniques were used to analyze statistically pretest and posttest scores derived from the sample. The .05 level of significance was used throughout the statistical analyses for rejection or retention of the null hypotheses. Preliminary analysis of data determined no systematic bias for teacher variability or for within group variability. Hypotheses 1, 2, 3, and 5 were tested using a 2 x 3 analysis of covariance. The pretest was used as the covariant in this analysis. No statistically significant differences in the classroom mean scores were determined between teaching methods, teaching methods with only girls as subjects, teaching methods with only boys as subjects, and boys and girls. Hypothesis 4, concerning the pretest differences between boys and girls, was tested using a t-test for independent samples. No statistically significant differences were found. From the findings several conclusions can be drawn. The receptive language of kindergarten children can be expected to improve when taught by any of the three selected oral language systems. Boys do not need different oral language experiences from girls; therefore the sex of the children need not be a major consideration when an oral language system is selected. Other factors which need not be major considerations in the selection of an oral language system are the race and socioeconomic level of the children.

Recent research in phonological awareness found a strong link between rhyming ability in preschool children and later reading achievement. The use of orthographic analogy, the ability to make inferences from similarities in spelling to similarities in sound, was proposed as the mechanism to explain this relationship (Goswami & Bryant, 1990). Literature was presented that suggested the need for further research. Four research questions were examined. First, can prereaders learn to read unfamiliar words on the basis of orthographic analogy after brief training with rhyming words? The evidence supported the view that they could. Second, will the ability to read words by orthographic analogy be enhanced by phonological training in onset and rime, and by the use of segmented text? The brief phonological training did not increase analogy word reading over the same training without it. However, using text segmented at the onset-rime boundary for training items did increase analogy word reading. Third, will reading by orthographic analogy vary according to the level of prereading skills (rhyming ability, phoneme identity, letter-sound knowledge)? The majority of children with high prereading skills learned to read analogy test words whereas most children with low prereading skills found the task too arduous. Fourth, will rhyming ability make an independent contribution to reading achievement? The results were equivocal. Rhyming ability did make an independent contribution to the number of trials taken to learn the training items. It did not when analogy word reading was the dependent variable. Phoneme identity accounted for most of the variance in analogy word reading. Further analyses found that the ability to identify the final phoneme was the best discriminator between children who learned to read analogy test words and those who did not. A possible explanation was that children used the final phoneme to determine the sound of the rime ending rather than the last two phonemes together. / Education, Faculty of / Educational and Counselling Psychology, and Special Education (ECPS), Department of / Graduate

This field study of two-year-old children using art materials in a preschool setting was concerned with how children constructed meaning about the art-making process through their interactions with others. The study was theoretically grounded in the work of George Herbert Mead, Herbert Blumer and Lev Vygotsky, who share a common view that meaning is socially constructed through interpersonal interactions. The study focused on children’s early use of art media and their social interaction as a significant factor in their artistic expression. Monthly videotaped and written observations documented four 2-year-aids’ participation with art media during their attendance at weekly parent-2-year old program. Over two subsequent years, the data were expanded to include observations of additional 2- year-aids, and parent and teacher interviews. Observations in a 3 and 4-year-old classroom coupled with extensive teacher interviews provided insights into teachers’ assumptions and values which guided their interactions. Observations of the 2-year-olds were coded into art episodes, and analyzed in terms of behaviours, interactions, and values. Based on Vygotsky’s idea that children’s shift from biological development to higher cognitive functioning occurs through interpersonal interaction, children’s exploratory use of materials was described. Analysis of their explorations revealed that intentionality and visual interest were crucial components in their art experiences. Analysis suggested that children as young as 2 years possess aesthetic sensitivity. There did not appear to be any single factor that could account for children’s selection or placement of colors or marks on a piece of paper. Social interactions around art-making occurred within spatial-temporal frames which contributed to the way the art-making context was defined by the participants. Through interpretations derived from interactions with peers and adults, children constructed understanding about cultural values for work, production, ownership, and neatness. They learned little about art skills or the relationship of their art-making experiences to art in the adult world. The study concludes with presentation of an interactionist model of children’s artistic expression which describes the dialectical relationship between biological development and social interaction. The model eliminates the need to debate issues around innate or cultural origins of children’s visual expression, through its inclusion of biological and social components. Using the interactionist model and Vygotsky’s notion of scaffolding can help teachers address conflicts surrounding the definition of developmentally appropriate art education for young children. / Education, Faculty of / Curriculum and Pedagogy (EDCP), Department of / Graduate

Effective training procedures are necessary when teaching behavior analytic techniques because the techniques are so complex and precise; and there is a correlation between the changed skills in the trainees to be beneficial to the client. Instructors who may previously exhibit effective teaching techniques in a one-to-one setting may not exhibit those techniques in an inclusive setting. This study examines the effects of a training package and an instruction on the performance of experienced instructors, and desired responding from both preschool-aged children with autism and typically developing peers. The training took place with 3 triads of one instructor, one child with autism, and one peer in a center-based inclusionary preschool. Instructor skills targeted were prompt and consequence delivery for the target social skills, getting attention and responding to peers. Corroborative data on children's responding were obtained.

The present study investigated the basic question: Will preschool, kindergarten, and first grade students have a greater increase in knowledge of selected nutritional concepts as a result of viewing a puppet story than a similar composite will have when the same material is presented via dramatic storytelling?

The concept of flow was examined in relation to the play behavior of preschool children. Thirty-five preschoolers were encouraged to play a beanbag toss game on three separate occasions called Phases I-III. In Phase I, children were allowed to match their skills to the challenges of the task in a choice condition. In Phase II, one group of 12 children again played the game under the choice condition. Two other groups of 11 and 12 children were required to play the game under conditions in which the challenges of the task were assumed to be either greater than or less than their levels of skill. In Phase III, all children again played the game under the choice condition. Five measures of the characteristics of flow, including number of attempts, percentage of successes, ratio of evaluation-seeking behaviors to number of attempts, ratio of off-task behaviors to number of attempts, and ratio of time spent off task to time spent on task were obtained for all phases. A repeated measures MANOVA with three groups and three phases was used to examine the data. A significantly greater number of evaluation-seeking behaviors per attempt were found at Phase I than at Phases II and III, regardless of condition. A significant phase x group interaction for the variable percentage of successes was also found. Post hoc analyses indicated that children in the assigned easy group had a significantly higher success rate at Phase II than at Phases I and III, while the assigned difficult group had a significantly lower rate. The percentages of successes between the three groups were significantly different at Phase II only. The single exposure to an assigned level of challenge may have been insufficient to produce the predicted effects on the characteristics of the flow experience. Subjective comments of the children obtained in Phase II indicated there were some differences in the levels of enjoyment of the task between the three groups. These subjective perceptions offer a possible explanation for the lack of differences on the measures of flow. The subjective comments indicate that throwing the beanbag at the target was enjoyable to the children regardless of their ability to hit the target; therefore the level of challenge may not have been critical. Several suggestions for future testing of the flow model are offered. / Ph. D.

This study examined the effects of a computer-mediated intervention on "at-risk" preschool students' receptive vocabulary development, computer-literacy skills, and enthusiasm for leaning. Twenty-two preschool-aged children attending an urban primary public school and participating in government subsidized school lunch program participated in the study. A pretest/posttest control-group design and case-study participant observations were used for data collection. Students were assigned to one of two treatment groups. Eleven preschool students with pretest School Readiness Composite (SRC) standard scores of 80, or below, on the Bracken Basic Concept Scale-Revised (BBCS-R), were assigned to the intervention group. Eleven pre-school students matched by age level and teacher comprised the comparison group. The intervention group received computer-mediated instruction while the comparison group received classroom teacher instruction. The first research question examined the effect of the intervention on students' receptive vocabulary analyzing groups' pretest and posttest BBCS-R School Readiness Composite mean scores. Combined analysis of a Two-Factor Repeated Measures and a Posttest only ANCOVA revealed that computer-mediated instruction was as effective as classroom teacher instruction in helping "at-risk" students acquire readiness receptive vocabulary. The second research question examined the effect of the intervention on "at-risk" student's computer-literacy skills analyzing participants pretest and posttest mean scores on the Computer Input Observation Rubric (CIOR), a rubric developed by the researcher. Analysis of One-Factor ANOVA and of Two-Factor Repeated Measures indicated that computer intervention significantly increased students' computer literacy skills. The third research question examined the impact of computer-mediated intervention on preschool students' enthusiasm for learning and followed descriptive case study methodology. Students' level of task involvement and positive-self statements confirmed enthusiasm for learning with technology.
