Students of Office Technology and Management (OTM) in Nigerian polytechnics have consistently performed below expectations both academically and at work. This may be attributed to use of inappropriate instructional method. The need to improve this situation necessitated the research on effects of peer tutoring on students’ academic achievement in OTM in Nigerian polytechnics.  Using a research question to guide the study, and a null hypothesis was tested at 0.05 level of significance. A non-randomized quasi experimental research design, adopting pre-test; post-test non-equivalent control group design was used. South West Nigeria was the region of the research work with a populace of 503 National Diploma Year II (ND II) OTM students in four federal polytechnics.  Using cluster random sampling, a sample of the intact classes of 227 students from two states in the area of the study was drawn. Three OTM experts validated the “Office Technology and Management Achievement Test (OTMAT)” 100 items instrument for face and content validity. The Experts input modified some items and cancelled some which reduced 140 test items to 100 used for collecting data. Descriptive statistics of mean was used to analyze data and to respond to the research question while t-test and Analysis of Covariance were used to test the null hypothesis. Kuder-Richardson Formula 21 was adopted to establish internal consistency and reliability of the instrument which yielded a coefficient of 0.86. The research showed that Peer Tutoring Instructional Technique (PTIT) has higher positive effects on students’ academic achievement in OTM than Teacher-dominated Instructional Approach (TDIA), thus it can enhance students’ academic achievement in OTM. It was, therefore, suggested that OTM lecturers should include the use of Peer Tutoring Instructional Technique to boost learning in teaching their students.

Academic knowledge and transfer of knowledge retention after graduation to the workplace by office technology and management (OTM) students in Polytechnics has been worrisome to stakeholders in education. This study seeks to determine if peer tutoring instructional technique could solve these aforementioned problems. The study adopted a quasi-experimental design of a pre-test, post-test and delayed posttest (knowledge retention) for non-randomized un-equal two groups. The population for the study is 503 National Diploma (ND) II OTM students in four Polytechnics in South West, Nigeria. Through purposive sampling, we selected a sample of 227 (120 experimental and 107 control) students from two polytechnics in two states. These instruments; lesson plan for the experimental group, lesson plan for the control group and Office Technology and Management Achievement Test (OTMAT), were used for data collection. Three OTM experts validated the instruments. The reliability coefficient of the OTMAT was established as 0.86 through the use of Kuder-Richardson formula 21 techniques. Mean and standard deviation were used to answer the research question while Analysis of Covariance (ANCOVA) was used to test the hypothesis. Results revealed knowledge gain for the experimental group. Thus, peer-tutoring enhances academic knowledge retention among OTM polytechnic students. It is therefore recommended that peer-tutoring instructional technique be used to teach OTM students in Polytechnics. Stakeholders should create platforms (workshops and conferences) for OTM lecturers and students in Polytechnics to utilize the peer-tutoring technique in the teaching/learning process.

Purpose Semi-occluded vocal tract (SOVT) exercises with tubes or straws have been widely used for a variety of voice disorders. Yet, the effects of longer periods of SOVT exercises (lasting for weeks) on the aging voice are not well understood. This study investigated the effects of a 6-week straw phonation in water (SPW) exercise program. Method Thirty-seven elderly subjects with self-perceived voice problems were assigned into two groups: (a) SPW exercises with six weekly sessions and home practice (experimental group) and (b) vocal hygiene education (control group). Before and after intervention (2 weeks after the completion of the exercise program), acoustic analysis, auditory–perceptual evaluation, and self-assessment of vocal impairment were conducted. Results Analysis of covariance revealed significant differences between the two groups in smoothed cepstral peak prominence measures, harmonics-to-noise ratio, the auditory–perceptual parameter of breathiness, and Voice Handicap Index-10 scores postintervention. No significant differences between the two groups were found for other measures. Conclusions Our results supported the positive effects of SOVT exercises for the aging voice, with a 6-week SPW exercise program being a clinical option. Future studies should involve long-term follow-up and additional outcome measures to better understand the efficacy of SOVT exercises, particularly SPW exercises, for the aging voice.

Among the various impediments to controlled research in applied settings are the difficulties attendant upon the withholding or withdrawal of treatment that might prove beneficial to subjects and the inability of researchers to present simultaneously treatment conditions to all subjects. The multiple pretest-posttest control group design is introduced as an efficient and effective remedy to the problems with special focus upon controls for internal and external validity threats. Several variations of this basic strategy, including the alternating model, the staggered model, and the multiple pretest-posttest replications design, are illustrated and discussed. Finally, the arrangement of factors for statistical analysis is presented for both the case of analysis of covariance with posttest scores and analysis of variance using corrected gain scores.

This study aimed at investigating the effect of the implementation of mind mapping learning method to the students’ social science achievement viewed from learning interest at the fourth-grade students of an elementary school in Denpasar city in the academic year 2016/2017. This study was quasi-experimental research which applied the posttest-only control group design involving 80 students of grade four at elementary school in Denpasar city who were selected by using the total sample sampling technique. The data of the students’ social science achievement and learning interest were collected and then analyzed using the Analysis of Covariance (Anacova). The result of this study showed that the students’ social science achievement who were treated with mind mapping learning method was higher compared to the students’ social science achievement of those treated with the conventional learning method. This difference was consistent even though the students’ learning interest has been controlled. Based on the result of this study, it is suggested that mind mapping learning method be applied in the teaching and learning process of social science at the elementary school.

Abstract Objectives The purpose of this exploratory non-randomized controlled study was to determine the acceptance and effectiveness of an 8-week mindfulness-based intervention (MBI) co-designed by a police officer. Methods A pretest-posttest control group design was followed. Participants (MBI group = 20; control group = 18) answered baseline and post-training self-reported measures. In addition, the weekly emotional state of the MBI group was collected. Paired-samples t-test and analysis of covariance were performed for pre-post within-group and between-group differences, respectively, as well as linear mixed effects analysis of repeated measures for week-by-week data. Results High acceptance and attendance rates, as well as significant pre-post within-group differences in the MBI group in mindfulness (η2 = 0.43), self-compassion (η2 = 0.43), depression (η2 = 0.54), anxiety (η2 = 0.46), stress (η2 = 0.51), difficulties in emotion regulation, sleep quality (η2 = 0.57), and burnout (η2 = 0.31–0.47), were identified. Moreover, police officers who underwent the MBI experienced a week by week decrease of anger, disgust, anxiety, sadness, and desire. Finally, after adjusting for pre-test scores, significant between-group differences were found in the way of attending to internal and external experiences (observing mindfulness facet; ηp2 = 0.21), depression symptoms (ηp2 = 0.23), general distress (ηp2 = 0.24), and the degree of physical and psychological exhaustion (personal burnout; ηp2 = 0.20). Conclusions The preliminary effectiveness of this MBI on psychopathology and quality of life outcomes in Spanish police officers was discussed. Previous evidence regarding the promising use of MBIs in this population was supported.
