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.

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.

The purpose of this study is to explore the influence of introduction of the physical computing strategy of Arduino Boards in a program design course on coding literacy and the effectiveness of the application in technical high school students. This study selected two classes of twelfth-grade students enrolled in a program design course at a technical high school in Southern Taiwan as the samples. One class was the control group (43 students), and the other was the experimental group (42 students). During the 18-week course, the control group carried out a DBL (design-based learning) programming project, and the experimental group carried out the DBL programming project using the physical computing strategy of Arduino boards. Pre- and posttests and a questionnaire survey were carried out, while ANCOVA (analysis of covariance) was used for evaluation purposes. In the course, students in the experimental group were randomly selected for semi-structured interviews to understand their learning status and to perform qualitative analysis and summarization. This study proposed the physical computing strategy of Arduino boards, featuring staged teaching content, practical teaching activities, and real themes and problem-solving tasks. The results show that the coding literacy of students in the different teaching strategy groups was significantly improved. However, in the Arduino course on DBL programming, the students in the experimental group had a significantly higher learning efficiency in coding literacy than those in the control group. Moreover, according to the qualitative analysis using student interviews, Arduino boards were found to improve students’ motivation to learn coding and to aid in systematically guiding students toward improving their coding literacy by combining their learning with DBL theory. Thus, Arduino technology can be effectively used to improve students’ programming abilities and their operational thinking in practically applying programming theories.

Background: The flipped classroom model provides an ideal ground to convert a traditional classroom into an interactive environment based on problem-solving learning with a focus on university students’ self-determination. Objectives: The present study aimed to investigate the effectiveness of flipped and traditional teaching methods in problem-solving learning and self-determination among university students. Methods: The research method was experimental with a pretest-posttest design and a control group. The statistical population included all female students of Farhangian University in Ahvaz city in the academic year 2019. Using a purposive sampling method, 36 students were selected and randomly divided into experimental and control groups (n = 18 per group). The research instrument included the Problem-Solving Inventory (PSI) and the Basic Psychological Need Satisfaction scale. The experimental group received the flipped teaching program during eight 120-min sessions once a week; however, the control group received the traditional teaching method. multivariate analysis of covariance (MANCOVA), univariate analysis of covariance (ANCOVA), and Bonferroni post hoc tests were used to analyze the data. Results: The posttest scores (mean ± SD) of problem-solving learning and self-determination were 83.77 ± 14.17 and 119.33 ± 13.79, respectively, in the experimental group, which were significantly different from the scores of the control group. The flipped classroom promoted problem-solving learning and components of self-determination among university students in the experimental group when compared to the control group (P = 0.01). The flipped teaching method was more effective than the traditional method in increasing problem-solving learning and self-determination among university students. Conclusions: According to the findings, the flipped teaching method had greater impacts on students’ problem-solving and self-determination than had the traditional method.
