Abstract Background Good oral health (OH) is essential for physical, social, mental health, and overall quality of life. This study assessed the usefulness of the theory of planned behavior (TPB) in changing oral health-related behaviors among school children aged 11–13 years in Saveh, Iran. Methods In this descriptive before and after study, participants were sixth-grade students at single sex primary schools in Saveh city, Iran. We recruited 356 school children in 2019. Using simple random sampling, a male and a female school per district were allocated to the experimental group and the remaining schools to the control group. Our planned oral health education consisted of four one-hour training sessions over 1 week. The first session familiarized the participants with important information about OH. In the second session, we applied a brain storming exercise to identify the benefits and barriers to flossing and brushing. In the third session, a short film about correct brushing and dental flossing technique was shown and research team also used role-playing to correct any mistakes. In the final session students were taught about the importance and the application of OH planning and given forms to help plan for brushing. Results Participants for the study included 356 students (180 in the experimental group and 176 in the control group) who completed the post-test questionnaire. The mean age ± standard deviation was 11.55 years ±0.93 in the experimental group and 11.58 years ±1.01 in the control group. After the intervention, the paired t-test indicated a significant difference between the mean and standard deviation of the action plan and coping plan constructs in the experimental group before and after the intervention (p < 0.05). Covariance analysis indicated a significant difference between scores of intervention and control groups under statistical control of post-test in two groups (covariate) after a peer-led education program (post-test) (p < 0.05). Conclusion A shortage of professional health workers in education settings together with the ease, usefulness and low-cost of this peer-led method, suggest further steps should be taken to implement it more widely to improve and enhance primary school aged students’ oral health behavior.

The objective of the research is to investigate whether or not there is a significant difference in the mastery of the speaking skill between the students who are taught by using classroom discussion and those who are taught without using classroom discussion. This study is a quasi-experimental study employing two groups. The experimental group is 8A and the control group is 8C. The data were collected by using an achievement test. The data of both pre-test and post-test scores from the control and experimental groups were analyzed by using inferential statistics. To test the hypothesis, the researcher used t-test to find out the differences of speaking skill mastery achievement between control and experimental groups. The result of post-test indicates that t o is higher than the t value at the significance level of 5%, i.e. 2.106<2.000. The level significance is 0.037. It is lower than 0.05. It was found that the mean of the post-test scores and gained scores of the experimental group were higher than that of the control group. The standard deviation of the experimental group decreases from 7.30 to 6.92 or the scores of the experimental group from pre-test to post-test are more homogenous. While, the standard deviation of the control group increases from 7.53 to 8.36 or the scores of the control group from pre-test to post-test are more heterogeneous. Besides, the mean of experimental group increases 207% from the standard deviation of the pre-test. While the mean of the control group also increases 147% from the standard deviation of the pre-test. It is found that classroom discussion is effective in improving English learning achievement in student’s mastery of speaking and there is a significant difference in between the both class.

Background/Objectives: This study examined the effects of introducing programming as a technological tool for teachers’ Technological Pedagogical Content Knowledge (TPACK) development.Methods/Statistical Analysis: Thirty-two teachers were divided into two groups, completing different types of TPACK educational programs. The control group’s TPACK training program was based on information and communication technology (ICT), while that of the experimental group was based on programming. To verify the effectiveness of the TPACK training program, tests were administered before and after the educational program. A statistical analysis of questionnaire results also investigated changes resulting from TPACK.Findings: Both the control and experimental groups showed statistically significant improvements in the post-test compared with the pre-test. However, in the detailed areas of TPACK by group, the improvements in the two groups differed. Unlike the control group, the experimental group showed a statistically significant improvement in the knowledge related to technology. This result illustrated that programming is effective in solving the problem of integrating technology into the classroom. In contrast, there was no significant difference in the post-test, as this was applied in the short term. However, programming has been shown to affect Technological Pedagogical Knowledge (TPK), Technological Content Knowledge (TCK), and TPACK. In summary, the results showed that a TPACK educational program based on programming is effective for teachers’ TPACK development. Keywords: TPACK, In-service teacher, Programming, TPACK-P, Educational program

The current study determines the effectiveness of using task-based language instructions in teaching writing at a high school in Thai Nguyen province. The participants consist of 92 grade 10 students from Bing Yen high school, Dinh Hoa district. The study employs a mix method research design (MMR) as the plan for the research. The results of the study reveals that the results of writing performance were reported at a low level (M=3.72). The results also confirmed that the intervention worked well for the experimental group. The mean score of the pre-test (the baseline for both groups) was M=3.72. The intervention focused on TBLT instructions. After first five weeks, the means of post-test1 were M=4.96 and M=3.83 for experimental group and control group respectively. There was a significant difference between the mean of pre-test and post-test1 for the experimental group (M=3.72 compared to M=4.96), while the control group showed a little improvement (M=3.72 compared to M=3.83) the difference was not significant. After another five weeks, the difference in the mean scores of the experimental group were far more than the mean scores of the control group, M=5.56 and M=4.45 respectively. By the end of the fifteenth week of the intervention, the mean of post-test 3 of the experimental group reached M=6.41, the mean for control group was M=5.54. The difference of the mean scores in the pre-test and post-test revealed a significant improvement in both groups. However, the experimental group showed a greater improvement, M=6.41 and M=5.54 respectively. It can infer that the uses of TBLT writing instruction improved writing achievement greatly.

This research was intended to investigate the effect of a culture-based approach in improving students’ reading comprehension on spoof text. For that purpose, a true experimental study was applied to the eleventh-grade students of SMAN 1 Soreang. The sample of this study was 88 students from that school. These students were divided equally into the control and experimental group. The experimental group was given the Culture-Based Approach (CBA) as the treatment in comprehending the text.  The students’ scores of pre-test and post-test from both groups were statistically analyzed and compared by the T-test. The findings could be summarized that generally, students from the experimental group gained better achievement than from the control group on their post-test scores. The data analysis also showed that there was a significant difference between the mean score of the pre-test (53.45) and the post-test (58.39.). Furthermore, the result of the t-test (5.707) was relatively higher than the t- table (2.018) for a 0.5 percent level of significance. It indicated that the students’ achievement was significantly improved after the treatment of using a Culture-Based Approach. Thus, it is recommended that a Culture-Based Approach should be considered as an alternative choice for English teachers in teaching spoof text.
