Comparison of Pre- and Posttraining Verbal Interaction of Caregivers and Children During Story Time

Description: The purpose of this descriptive study was to create a read-aloud instructional program which could be used in teaching caregivers to promote quality verbal interaction among participants during story time. Prior to and subsequent to instruction, selected high-school students participating in a vocational-technical child development program were audio- and videotaped as they read stories aloud to children. All tapes were transcribed in full. Using the storybook Reading Analysis System (Teale, Martinez, & Glass, in press), dialogue was categorized into form, type of information, focus, instructional intent, and importance categories.

A Comparison of Profiles of Success in Two Instructional Methods

Description: The problem of this study was to isolate predictors of academic success in both self-paced classes and lecture classes in Introductory Accounting. The purposes of the study were to determine if learning style, locus of control, reading ability, age, sex, accounting work experience, and prior accounting academic experience are predictors of success in Introductory Accounting classes taught using self-paced methods of instruction and lecture methods of instruction. Another purpose was to determine if there is a difference in the set of predictors of success in the two instructional methods and to provide some direction as to determinants of success which may be addressed by counselors in advising students. The data were collected from 463 students at a suburban community college in the Southwest. Each of the variables was analyzed by a stepwise multiple regression analysis and a backward elimination regression for students grouped according to instructional method. A two-way multivariate analysis of variance was used to examine whether the distribution of scores on the potential predictor variables were equivalent for students in the two teaching methods and for successful completers of the course and noncompleters. Consideration of the data findings of this study permitted the following conclusions: 1. Age and reading ability have a positive relationship to academic success in an Introductory Accounting course taught in a lecture format. 2. Concrete learning style, as measured by the Learning Style Inventory, age, reading ability, and accounting work experience have a positive relationship to success in an Introductory Accounting course taught in a self-paced format. 3. Age, reading ability, accounting work experience, and a concrete learning style have a positive relationship to academic success in Accounting courses taught using either method. 4. There is a difference in the set of predictors of success for Accounting classes taught using the two instructional methods. ...

A Comparison of Recall by University Bible Students After Discussion and After Self-Study

Description: Recall of expository prose after one of two learning techniques was determined. Pearson correlation did not discover a significant difference between the recall writings of the examinees who studied by discussion and those who studied by underlining. The significance of the difference between two proportions found that the group which underlined recalled significantly better than the group which discussed what they had read. This highly significant difference was almost identical when all synonyms from the Turbo Lightning computer program were considered correct recall and analyzed by the significance of the difference between two proportions.

A Comparison of Some Continuity Corrections for the Chi-Squared Test in 3 x 3, 3 x 4, and 3 x 5 Tables

Description: This study was designed to determine whether chis-quared based tests for independence give reliable estimates (as compared to the exact values provided by Fisher's exact probabilities test) of the probability of a relationship between the variables in 3 X 3, 3 X 4 , and 3 X 5 contingency tables when the sample size is 10, 20, or 30. In addition to the classical (uncorrected) chi-squared test, four methods for continuity correction were compared to Fisher's exact probabilities test. The four methods were Yates' correction, two corrections attributed to Cochran, and Mantel's correction. The study was modeled after a similar comparison conducted on 2 X 2 contingency tables and published by Michael Haber.

A Comparison of the Effectiveness of the Intensive and Concurrent Scheduling Plans for Teaching First-Semester English Composition in the Community College

Description: The purpose of this study was to observe the differences in English achievement, critical-thinking ability, and attitude toward subject attributable to two scheduling approaches -- "Concurrent" and "Intensive"--in the teaching of first-semester freshman English composition to community college students. Further, the study was initiated in order to provide factual information as a basis for administrative and instructional judgments affecting future planning for accelerated scheduling at the experimental institution. Two classes of first-semester freshman English composition, meeting three hours weekly for fifteen weeks, comprised the control group (Concurrent); two classes of first-semester freshman English composition, meeting nine hours weekly for five weeks, comprised the experimental group (Intensive). The same form of three criterion instruments was administered to both groups before and after the experimental treatment. The instruments were the Cooperative English Expression Test, the Watson-Glaser Critical Thinking Appraisal, and the Purdue Attitude Scale, Part A -- Attitude Toward Any Subject. Three instructors were involved in the experiment during the fall and spring semesters of the 1973-74 school year. Conventional methods of instruction, using the same course of study, were duplicated in all situations. Statistical analyses utilized in the study were analysis of covariance and multiple linear regression. It was felt that Intensive scheduling was superior to Concurrent as a means of promoting student-faculty harmony. Also, the frustrations experienced within the traditional classroom situation could be lessened by granting greater freedom from the constraints of hourly schedules and competing classes. With tensions reduced, English proficiency could be increased. Acting upon these suppositions, three hypotheses--related to each of the criterion measures-- were formulated. All hypotheses stated that the adjusted post-test scores for the experimental groups would be significantly greater than the adjusted post-test scores for the control groups. The results of the experiment, however, showed no significant difference for any of the hypotheses ...

Comparison of the Effectiveness of Two Interentions for the Treatment of Agoraphobia

Description: The problem with which this investigation was concerned is that of treating agoraphobia with cognitive-behavioral group therapy and cognitive-behavioral group therapy combined with the drug alprazolam (Xanax). The purpose of the research was twofold. The first goal was to determine the relative effectiveness of the two treatment conditions on phobic behavior, anxiety, and depression. A second goal was to analyze the results and make recommendations concerning each of these modalities available to agoraphobics, their families, and to treatment specialists. The research design of this study was a randomized, pretest-posttest, experimental group design. The sample (N = 15) consisted of Group I (N = 7), who received behavioral-cognitive group therapy combined with the medication alprazolam, and Group II (N = 8), who received behavioral-cognitive group therapy only. The treatment included 15, 2-hour weekly group sessions, with the addition of a brief medication evaluation prior to each group meeting for Group I. During these sessions, the subjects received information about agoraphobia in the form of brief didactic segments, treatment materials, homework assignments, group interaction, and various forms of desensitization. Based on the findings of this study, the following conclusions were drawn: 1. Multidimensional behavioral-cognitive group therapy can significantly reduce phobic avoidance, anxiety, and depression associated with agoraphobia; and 2. Multidimensional behavioral-cognitive group therapy in combination with administration of alprazolam, can significantly reduce phobic avoidance and anxiety associated with agoraphobia.

A comparison of the Effects of Different Sizes of Ceiling Rules on the Estimates of Reliability of a Mathematics Achievement Test

Description: This study compared the estimates of reliability made using one, two, three, four, five, and unlimited consecutive failures as ceiling rules in scoring a mathematics achievement test which is part of the Iowa Tests of Basic Skill (ITBS), Form 8. There were 700 students randomly selected from a population (N=2640) of students enrolled in the eight grades in a large urban school district in the southwestern United States. These 700 students were randomly divided into seven subgroups so that each subgroup had 100 students. The responses of all those students to three subtests of the mathematics achievement battery, which included mathematical concepts (44 items), problem solving (32 items), and computation (45 items), were analyzed to obtain the item difficulties and a total score for each student. The items in each subtest then were rearranged based on the item difficulties from the highest to the lowest value. In each subgroup, the method using one, two, three, four, five, and unlimited consecutive failures as the ceiling rules were applied to score the individual responses. The total score for each individual was the sum of the correct responses prior to the point described by the ceiling rule. The correct responses after the ceiling rule were not part of the total score. The estimate of reliability in each method was computed by alpha coefficient of the SPSS-X. The results of this study indicated that the estimate of reliability using two, three, four, and five consecutive failures as the ceiling rules were an improvement over the methods using one and unlimited consecutive failures.

A Comparison of the Problem Solving Ability of Physics and Engineering Students in a Two Year College

Description: The problem with which this study was concerned is a comparison of the problem solving ability of physics and engineering students in a two year college. The purpose of this study was to compare the problem solving ability of physics and engineering students in a two year college and determine whether a difference exists. Data was collected from an instrument administered to twenty-six engineering students and twenty-three physics students as a major examination in their regular courses. The instrument was validated by being taken from representative texts, by approval of the instructors using the examination, and by approval of a physics professor at a university. The instructors and professor were considered a panel of experts. Comparison of test scores of students who were registered in both physics and engineering and who took the exam twice, established concurrent validity of the instrument. A questionnaire was also administered to both groups of students to determine their personal problem solving strategies, if any, and to collect other demographic data. Additional demographic data, as available, was 2 obtained from the registrar. Instructor profiles were determined from interviews with each of the four instructors involved. Analysis of the data indicated there is a significant difference in the ability of engineering students and physics students to solve statics problems. The engineering students scored significantly better in solving both engineering problems and in overall problem solving, as hypothesized. The engineering students also scored significantly higher in problem solving ability on physics problems, resulting in the rejection of the hypothesis that there would be no difference in the problem solving ability of the two groups on physics problems.

A Comparison of the Teaching of History in Teacher Colleges in the Metropolitan Region and Other Regions in Thailand

Description: The purpose of this study is to compare and analyze the teaching of history in teachers colleges in the Metropolitan region and other regions in Thailand. Variables examined in this study include the following: salary, teaching experience, degrees held, the number of graduate credit hours in history, the number of graduate credit hours in education, attendance at professional meetings, the number of publications, membership in professional organizations, the number of hours devoted to course preparations, teaching load, and teaching behaviors. The comparison is based on geographical location of the teachers colleges by region. The survey instrument, after intensive review and validation by selected faculty both in Thailand and the United States, was distributed to the 180 history instructors in the teachers colleges in the six major regions of Thailand. The total number of responses was 138, or 76.7 per cent. The statistical procedures used in the analyses of data include frequency and percentage of responses, a chi square test of independence, t test, the Yates* correction for continuity, and Fisher's Exact Probability Test (2-tailed). The data findings from this study indicate that there is a high degree of similarity between the respondents from the Metropolitan region and other regions' history instructors in Thai teachers colleges with respect to the majority of the criteria. Although some significant differences were found, it would be difficult to state that there is a difference between history instructors in the Metropolitan region and other regions groups. Recommendations are made for the history instruction programs in Thailand based on the responses from both groups and the information gathered from a review of the literature.

A Comparison of Two Methods of Training Naive Users in the Use of a Microcomputer System

Description: The problem addressed in this study is the need for efficient and economic methods to train naive college students to operate microcomputers as a necessary step in their acquisition of computer proficiency. Two methods of training were compared. These were training by live demonstration and training by videotape. These methods were considered economically viable because each could be presented in a classroom and neither required a one-to-one student-to-computer or student-to-tutor ratio. Four sections of an introductory computer science class were used in the study. Two classes were presented each treatment. The effectiveness of the presentations was measured by means of a written quiz administered immediately after the presentation and by the number of microcomputer system operation tasks successfully completed during an individual laboratory session. The computer anxiety level of each participant was measured prior to the presentation to determine if anxiety was a factor in finding the best training method. When scores of naive users who saw the videotape were compared with the scores of naive users who saw the live demonstration, no significant differences were found. However, when novice users (those who had some previous experience with operating or programming a microcomputer) were included, the group that saw the videotape scored significantly higher on the written quiz than the group that saw the live demonstration. A two by two analysis of variance showed no significant interactions between anxiety and treatment. User satisfaction was found to be significantly higher for the videotape group than for the live demonstration group. This study concluded with the recommendation that the Computer Science Department of North Texas State University utilize videotapes to train students in introductory classes to use a microcomputer system. This recommendation was based on the superior test results for naive and novice users who saw the videotape, the user satisfaction scores ...

A Comparison Study of Individual and Group Play Therapy In Treating Kindergarten Children with Adjustment Problems

Description: This study was designed to determine the effectiveness of individual child-centered play therapy in the elementary school in: 1) enhancing the self-concept of kindergarten children who are experiencing adjustment difficulties; 2) decreasing the overall behavioral problems of kindergarten children experiencing adjustment difficulties 3) decreasing externalizing behavior problems such as aggression and delinquency of kindergarten children experiencing adjustment difficulties; 4) decreasing the internalizing behavior problems such as withdrawal, somatic complaints, anxiety and depression of kindergarten children experiencing adjustment difficulties; 5) increasing parental perception of change in the problematic behaviors of kindergarten children experiencing adjustment difficulties; and 6) enhancing self-control in kindergarten children experiencing adjustment difficulties. A secondary objective was to compare the participants involved in individual child-centered play therapy with participants in a previous study who were involved in child-centered group play therapy on the above named dimensions. The experimental group, consisting of 14 kindergarten children experiencing adjustment difficulties, received 10-12, 30-minute individual play therapy sessions in a 12 week period in their elementary school. The comparison group, utilized from the 1999 McGuire study, consisted of 15 children with adjustment problems and received 12-14, 45-minute group play therapy sessions in 14 weeks in their elementary school. The control group, consisting of 13 children experiencing adjustment problems, received no play therapy intervention over a 12 week period. An Analysis of Covariance revealed significant findings in 1 of the 6 hypotheses and one subscale hypothesis examining the effectiveness of individual play therapy versus the wait list control group. Specifically, children with adjustment problems in the experimental group exhibited a significant reduction in total behavior problems and a significant reduction in externalizing behavior problems as measured by the Child Behavior Checklist-Parent Form (CBCL). Additionally, an Analysis of Covariance revealed significant findings in 1 of the 6 hypotheses examining the comparison of the effectiveness of ...

Comparisons of Improvement-Over-Chance Effect Sizes for Two Groups Under Variance Heterogeneity and Prior Probabilities

Description: The distributional properties of improvement-over-chance, I, effect sizes derived from linear and quadratic predictive discriminant analysis (PDA) and from logistic regression analysis (LRA) for the two-group univariate classification were examined. Data were generated under varying levels of four data conditions: population separation, variance pattern, sample size, and prior probabilities. None of the indices provided acceptable estimates of effect for all the conditions examined. There were only a small number of conditions under which both accuracy and precision were acceptable. The results indicate that the decision of which method to choose is primarily determined by variance pattern and prior probabilities. Under variance homogeneity, any of the methods may be recommended. However, LRA is recommended when priors are equal or extreme and linear PDA is recommended when priors are moderate. Under variance heterogeneity, selecting a recommended method is more complex. In many cases, more than one method could be used appropriately.

Competencies Required for the Design and Implementation of Manufacturing Systems for Advanced Composite Structures

Description: The problem with which this investigation is concerned is that of identifying and prioritizing the competencies required to design and implement manufacturing systems for advanced composite structures. The classical Delphi procedure is the research method used for the conduct of this study. A five-member advisory board developed a list of seventeen categories under which the competencies would reside. In the first-round questionnaire, the seventeen categories were presented to a Delphi panel of experts who provided up to five competencies required in each category. The first-round returns provided two new categories and 973 competency statements. Duplications were eliminated and 366 competency statements remained in nineteen categories. The second, third, and fourth rounds were a reiterative rating process. The panel was asked to rate the items in the questionnaire based on their relative importance to the intent of the study. The importance rating scale included "very important," "important," "slightly important," and "unimportant." The means and interquartile ranges were calculated for each statement and provided as feedback in the successive round. Kendall's coefficient of concordance W for tied ranks was used to validate the panel consensus. The W was significant at the .01 level for each of the three rounds where rating was performed. The data were presented in rank order within categories by importance level. Eighteen percent of the competency statements were rated "very important," 77 percent "important, and 5 percent "slightly important." No statements were rated "unimportant" by the panel. It was concluded that, as indicated by the 19 categories and 366 competencies, the scope of the requirements for designing and implementing manufacturing systems for advanced composite structures represent a broad range of knowledge and skill requirements. The breadth of the range of the requirements indicated the need for the development of areas of specialization within the subject field to adequately ...
