This paper presents a research conducted in Teluk Intan Community College aimed to evaluate the effectiveness and usability of integrating the Augmented Reality (AR) technology as an aid for animation course in Teluk Intan Community College. The focus was to integrate AR tool as an aid for students in the task of 3D modelling. For this research, the intended outcome is to compare the effectiveness between using the AR tool and written tutorial. The AR tool which later be called as ARC-3DM (Augmented Reality Courseware for 3D Modelling) will be developed and be tested in the experiment. Quantitative approach and quasi-experimental design were used in the study. A total of 54 animation students are involved in the study. The students were divided into two groups: control and treatment. A pretest and posttest were conducted to both groups. System Usability Scale (SUS) Questionnaire were administered to treatment group after the posttest to evaluate usability. Statistical methods involved were descriptive analysis and the analysis of covariance (ANCOVA) with the pretest as the covariate  at significant level of 0.05 was conducted to answer the hypothesis. The results indicate that the treatment group performed better than the control group in completing the task of 3D modelling. In terms of usability, the results showed that most of the students agreed on the usability in the ARC-3DM.

As the construction industry advances technologically, it becomes imperative to introduce the respective information technology tools to present-day curriculum. This research study was conducted to identify any significant differences in student performance contributed by using an information technology tool, specifically the Apple® iPad® tablet. IPad tablets were used to electronically present construction drawings to a treatment group, and a control group was given traditional paper drawings. Following an instructional lecture, students were given a test based on the provided construction drawings. The test results indicate that there was no significant difference in performance between students who used the information technology tool to complete the test and those who used traditional paper drawings to complete the same test. The treatment group also answered a usability survey, which helped to comprehend how students perceive the tablet’s usability. Students indicated that they would like to use the tool in the future.

Background: We aimed to systematically evaluate the efficacy of high-voltage pulsed current (HVPC) in the treatment of pressure ulcer. Methods: We searched the databases of PubMed, Cochrane Library, Elsevier and EMBASE to identify randomized controlled studies on the application of HVPC in pressure ulcer treatment, up to January 2019. Two authors independently screened the literature according to the inclusion and exclusion criteria, extracted the data and evaluated the quality. RevMan 5.3 software was used for statistical analysis. Four randomized controlled trials involving a total of 176 patients were included in the study. Results: Meta-analysis showed that the percentage of wound area reduction in the HVPC treatment group was higher than that in the control group (95%CI 24.59, 47.76, P<0.001). Descriptive analysis showed that there was no significant difference in wound healing between the HVPC treatment group and the control group. One study reported that there was contact dermatitis, and the rest of the studies reported no adverse events. Conclusion: Compared with the conventional therapy, the combination with HVPC therapy can reduce the area of pressure ulcers more effectively. However, due to the small number of the studies included in this evaluation, the conclusions need to be verified by more high-quality studies.

Two Parameters

When two groups are compared in a pre-post study, two different conclusions can be drawn between the two-sample t-test and the analysis of covariance (ANCOVA). It is known as Lord's Paradox, and it occurs because the parameter in the two-sample t-test and the parameter of interest in the ANCOVA model are not the same quantity. The difference between the two parameters can be explained by the covariance of linearly combined random variables which is an important topic in introductory statistical theory courses. Lord's paradox is frequently observed in practice, and it is very important for students (future researchers) to have clear understanding of the paradox. The objective of this article is to explain Lord's Paradox using the covariance of linearly combined random variables. The paradox is explained using three scenarios in the context of educational research. The first scenario is when the average baseline (pre-score) is greater in the treatment group than the control group, the second scenario is when the average baseline is lower in the treatment group than the control group, and the third scenario is when the average baseline is same between the two groups by randomization. This article is written at the level of introductory statistical theory courses for undergraduate and graduate statistics students to help understanding the difference between the parameter of interest in the two-sample t-test and the parameter of interest in the ANCOVA model.

Mobile augmented reality (MAR) draws attention in terms of providing a flexible learning process and environment. It is thought that learning environments can be more effective using MAR technology. The research aimed to determine the secondary school students' views on the use of MAR technology in science teaching. The research was conducted with 143 students studying in the sixth grade at two different secondary schools in Turkey. In the research, convergent parallel patterns from mixed-method patterns were used. For eight weeks, the research was carried out to cover the systems unit in our body, situated in the 6th-grade science course curriculum. During the process, the Anatomy 4D application was used in the experimental group during the procedure, and the science course curriculum was used in the control group.  In this paper, a part of the mixed research, the qualitative data collected from the experimental group's semi-structured interview form and diaries were analyzed. Descriptive analysis was used to analyze the data. As a result of the research, although the students do not have a clear idea about AR and MAR technologies at the beginning of the application, it is observed that their thoughts change over time, and MAR applications are effective on the success of the course.

Background: Bullying and the lack of social skills are essential for future risk-related problems, such as delinquency and feelings of rejection in children. The present study aimed to assess the effects of coloring mandala as Jungian art to reduce bullying and increase social skills in Afghan male working children. Methods: It was a quasi-experimental study with a pre-test, post-test and a control group design. The research population included all 10- to 12-year-old Afghan immigrant boys in Tehran City, Iran, who were studying in Parto School for Working Children, in 2019. The research sample consisted of 30 children who have obtained maximum scores on the Illinois Bully Scale (IBS) and minimum scores on the Teenage Social Skills Inventory (TSSI). The research participants were selected using a convenience sampling method. Then, they were assigned to the control and treatment groups by drawing lots. The treatment group attended ten 45-minute sessions of coloring mandalas and Jungian art. The data collection tools were the IBS: Student Version (Espelage & Holt, 2001) and the TSSI (Inderbitzen & Foster, 1992). The data were analyzed using the one-way Analysis of Covariance (ANCOVA) in SPSS. Results: The present research results suggested that the bullying scores for the participants in the treatment group significantly decreased at the post-test, compared to the pre-test (F=24.29, P=0.001); however, their social skills scores significantly increased at the post-test, in comparison with the pre-test (F=42.41, P=0.001). However, no significant differences were found in the bullying and social skills scores of the controls between the pre-test and post-test phases. Conclusion: Mandala coloring art was effective in reducing bullying behaviors and increasing social skills among the explored Afghan migrant working children. Therefore, this artistic method can be used as a suitable option for psychological therapies, teaching social skills, and creating participation and empathy in children in educational centers and schools for child labor.

This study evaluates the effect of a school programme called PRODIGY that uses counseling skills to motivate students in rural areas in Perak, Malaysia. A total of 78 students (N = 78), who were 12 years of age participated in this study. The effect of the programme was measured by comparing the difference between mean scores of the pretest and the posttest. The instruments used to measure school motivation were (a) Elementary School Motivation Scale by Guay, Marsh, Dowson and Larose (2005) and (b) Intrinsic and Extrinsic Motivation by Harter (1981). Descriptive analysis was used to find the difference in mean scores and the standard deviation of the data. Results show that the mean score among students from the treatment group was higher compared to the control group. Teachers commented that children in the treatment group were more confident and took the initiative to meet with teachers whenever they have difficulties in their studies.
