Effects of a Brain Improvement Program on Students' Reading Achievement

Description: How to close the reading achievement gap among K-12 students is an ongoing emphasis for educators in the 21st century. The purpose of the study was to determine if using kinesthetic movements from the Brain Gym® program improved the reading achievement of Grade 3 Hispanic and African American students. Students from four elementary schools participated in the study. The students in the control and experimental groups completed a 2004 release TAKS third grade reading assessment for the pretest and posttest. Students in the experimental group completed five selected kinesthetic movements from the Brain Gym® program five minutes at the beginning of each Monday through Friday school day. The intervention lasted 30 days and a total of 150 minutes. Data were analyzed using a 2 x 2 mixed between-within subjects analysis of variance. Findings revealed that performing the five kinesthetic movements from the Brain Gym® program did not increase students' reading achievement scores. Only the variable of time between pretest and posttest affected students' reading scores. The results from this study did not support the findings of other studies of the effectiveness of kinesthetic movements.

The Effects of a Career Education Program on the Career Choices of Fifth-grade Students.

Description: The career development of students, demonstrated by students' career interest, is important for a more effective career education program. This study focused on the career choices of fifth grade students through the use of a career interest inventory before and after the use of a career education program. The design was experimental, and the purpose was to determine if there were differences in the career interest of fifth grade students who participated in a career education program compared with the career interest of fifth grade students who did not participate in a career education program. The COPS-PIC Picture Inventory of Careers (COPS-PIC) was used as a pretest and posttest for fifth grade students to determine baseline career interests. The COPS-PIC career inventory results were incorporated into the career education program and served as a career planning guide for incorporating students' input into career choices and exploration of those choices for a better understanding of the process of finding out who they want to be and what type of careers exists. The experimental group was provided instruction and career exploration opportunities for 4 weeks. The control group was not provided career education instruction and career exploration opportunities. This study suggests that fifth grade students who participated in a career education program were able to make more concentrated career choices at higher levels of interest after participating in the career education program. Additional studies that include the use of career interest inventories and a career education program are needed before extensive generalizations can be made.

The Effects of a College Human Sexuality Course on Students' Sexual Knowledge, Attitude, and Behavior.

Description: Using an experimental-comparison group design, data were collected at the beginning and end of a semester to assess the effect of a human sexuality course on students' sexual knowledge, sexual attitude, and sexual behaviors. Data analysis by t-tests showed statistical differences between the experimental and comparison group only on sexual knowledge scores ( p < .001), with the experimental group scoring higher. T-tests showed statistical difference between males and females in sexual attitude (p< .001) and sexual behavior (p< .001) with women scoring higher than men in the experimental group, and also when experimental and control groups were combined. Although not statistically significant, women scored higher in sexual knowledge than males.

The Effects of a Computer-Assisted and Managed Learning Program on Test Outcomes in a Basic Communication Course

Description: The problem of this investigation was concerned with the effects that a computer-assisted and managed learning program had on the test outcomes of college students enrolled in a basic communication course. The purpose of the study was to determine the effects of participation in a computer-assisted and managed learning on the test outcomes of college students enrolled in a basic communication course. In order to facilitate the experiment, four hypotheses were formulated: 1. There will be significant differences in the posttest scores among the three groups. More specifically (a) the computer-assisted and managed learning (CAML) group will have significantly higher posttest scores than the teacher-assisted learning (TAL) group and the control group. 2. Computer apprehension will be significantly lower for students assigned to the CAML program, than students assigned to the TAL or control groups. 3. Computer complexity will be significantly lower for students assigned to the CAML group, than the students assigned to the TAL or control groups. 4. Computer utility will be significantly higher for students assigned to the CAML group, than students assigned to the TAL or control groups. Two experimental and one control group was used in the study. The experimental groups consisted of CAML (computer-assisted and managed learning) and TAL (teacher assisted learning). The control group was not treated with assisted instruction or practice testing. There were significant differences found among the posttest scores of the three groups. Students assigned to the CAML and TAL groups did have significantly higher posttest scores than students assigned to the control group. Although there were observable differences in the posttest scores between CAML and TAL, the differences were not statistically significant. Computer apprehension was significantly lower for the CAML group than the TAL or Control groups. Computer complexity was significantly lower for CAML than the TAL or Control ...

Effects of a Computer-based Self-instructional Training Package on Novice Instructors’ Implementation of Discrete Trial Instruction and a Naturalistic Developmental Behavioral Intervention

Description: Discrete trial instruction (DTI) and naturalistic developmental behavioral interventions (NDBIs) are often incorporated into early intensive behavioral interventions for young children with autism. Recent advances in staff training methods have demonstrated that self-instructional manuals, video models, and computer-based training are effective and efficient ways to improve staff implementation of these teaching strategies however research in this area is limited. The current evaluation assessed the effects of a computer-based training package including self-instructional manuals with embedded video models on direct-care staff’s implementation of DTI and an NDBI. All participants’ DTI teaching fidelity increased during role-plays with an adult and with a child with autism and all participants increased teaching fidelity across untrained instructional programs. In addition, moderate improvement was demonstrated following NDBI training on the use of correct prompts, environmental arrangements, and response interaction. Together, these results indicate that therapists are able to acquire a large number of skills using two teaching techniques, DTI and NDBI, following brief computer-based training.

The Effects of a Computer-mediated Intervention on "At-risk" Preschool Students' Receptive Vocabulary and Computer Literacy Skills.

Description: 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.

The Effects of a Conflicting Instruction on a Fr 5 Performance

Description: The purpose of this experiment was to evaluate the effects of a conflicting instruction on FR-5 performances by an ABABC design. After all four college students were consistently pressing 1-5-3 followed by sound-clips, the schedule value changed to FR-5 (A). Then they were presented with the written instruction "Press 426" (B) in addition to the previous condition. In the last condition (C), 1-5-3 responses were then scheduled for extinction in three participants and the reinforcer was changed from sound-clips to points for one participant. The results showed that unlike previous experiments, instructions did not override the scheduled contingencies. Instruction-following occurred only when there were no other contingencies (i.e., extinction of 1-5-3) or the scheduled reinforcer for FR-5 performances was weak.

The Effects of a Feedback Package on the Facial Orientation of a Young Girl with Autism During Restricted and Free Operant Conditions

Description: A multiple baseline design across activities and people was used to assess the effectiveness of a feedback package on the facial orientation of a young girl with autism. During baseline, observations indicated low rates of facial orientation and high rates of gaze avoidance during conversation (restricted operant) and play (free operant) conditions. After treatment, facial orientation rates increased and gaze avoidance rates decreased to levels similar to typically-developing peers and maintained at one month follow up. These results suggest that the feedback package was effective in producing durable facial orientation across different environments and people. Possible interpretations, strengths, and limitations are discussed.

The Effects of a Group Parent-coaching Package on the Behavior of Children with Autism and Their Parents

Description: Support for parents is an important part of treatment programs for children diagnosed with autism. Parent training programs have generally focused on prescribed goals in one-on-one training settings with measures directly related to the goals. Of interest here are the few studies that included collaborative goals, expanded measures, and group training. Benefits of such approaches include the establishment of natural communities of reinforcement and better understanding of the breadth of effects. The purpose of this study was to determine if a group coaching approach would be effective in changing a large range of parent and child skills. This experiment involved group sessions (presentations, discussion, video sharing, and problem solving) and three individual in-vivo coaching sessions. The intervention took place over the course of four weeks. Direct measures included a parent skills checklist and child target behaviors. Results indicated an overall improvement on most measures that maintained or improved at follow-up.

The Effects of a Human Developmental Counseling Application Curriculum on Content Integration, Application, and Cognitive Complexity for Counselor Trainees.

Description: Although professional counselors have distinguished themselves among helping professionals through a focus and foundational framework in normal human growth and development over the life-span, a majority of programs neglect to incorporate training opportunities enabling students to translate developmental theory to clinical practice. In this mixed-method study, the researcher explored the effects of a human developmental counseling application curriculum and examined cognitive complexity levels among counselor trainees. Qualitative results support gains in both the integration and application of developmental content while quantitative results offer partial support for cognitive complexity gains among trainees. This study identifies a curricular training experience in which counselor trainees' integration and application human developmental theory as well as cognitive complexity, are notably enhanced.

The Effects of a Human Resources Information Technology Intervention on Background Check Processing in a Financial Institution: a Process Level Analysis.

Description: The human resources department of a financial institution implemented a multi-component intervention to replace a paper-based hiring system. Organization-wide impacts included changes in the background check operations. To support changes, training was conducted and procedure manuals distributed. Turn time for background checks decreased, but a combination of factors may be responsible. Other metrics are either inconclusive or suggest a confounding variable, yet quality of work did not suffer was maintained. Desired system use was achieved, accompanied by improvements in time-to-fill, voluntary turnover, and quality of applicants. Considerations for analysis and challenges faced are discussed, along with suggestions for further clarification and improvements.

The Effects of a Human Trafficking Prevention Workshop Package on Participant Written and Simulation Responses

Description: This study evaluated the effects of a community workshop designed to teach community members about human trafficking prevention. Participants were trained to identify the critical and non-critical features of human trafficking and safe ways to respond to identified trafficking situations. A pre-post treatment design was used to assess the effects of a community workshop across written and verbal target behaviors. This included written responses as well as simulation assessments across five different trafficking scenarios. Results indicate that all participants engaged in more correct responding within the written assessment and asked specific relevant questions with greater confidence within the simulation assessment following training. However, social media and empathy responses following the workshop did not differ from baseline. This study is one of the first empirical studies aimed at formally evaluating the effects of human trafficking prevention workshops. Results are discussed in the context of instructional design, measurement of outcomes, and interdisciplinary collaboration.

The Effects of a Kindergarten-First Grade Looping Program on Academic Achievement and Self-Esteem

Description: The purpose of this study was to determine if academic achievement and academic self-esteem can be linked to the non-traditional organizational pattern of looping in kindergarten and first grade classes. Looping is defined as one teacher remaining with the same students for two or more years. Using a control group-experimental group design where the experimental group participated in the looping program and the control group did not, and applying the statistical procedure of multivariate analysis of variance (MANAVO), it was found that there was no significant difference between the subjects in the two groups on the criterion variable of academic achievement as measured by the Iowa Test of Basic Skills, and the criterion variable of academic self-esteem as measured by the Culture-Free Self-Esteem Inventory, Second Edition. It was concluded that further study would need to be done to determine if there are advantages to an organizational pattern of looping for students in public elementary schools.
