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” students' 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.
