One of the topics students have understanding difficulties in science is pressure. The study investigates the effectiveness of an active-learning environment on the students' understanding of the concept of pressure. The sample consisted of 30 students from a public secondary school in Turkey. This study used a pre-test, post-test, quasi-experimental research design with a control group. Ten lessons were conducted with both groups. The control group was taught using the coursebook's two activities, while the experimental group was taught using additional activities and models. After the treatment, a post-test was given to both groups to determine the active-learning environment's effectiveness on the students' understanding of the concept of pressure. Interviews were also conducted with the experimental group. The post-test results showed a significant difference in favor of the experimental group. It was determined that students in both groups had misunderstandings of the topic before and after instruction. The interviews showed that the experimental group students perceive that the active learning environment facilitated better and easier learning. The conclusion that can be drawn is that the active learning environment was more effective for the students in the experimental group to learn about the concept of pressure.

This research was designed to find out the effects of vocabulary analogy to reading comprehension of seventh grade students of State Junior High School 9, Yogyakarta, Indonesia. Specifically it sought to answer the following questions: 1) How is the effects in reading comprehension of the students taught with  Vocabulary  Analogy  or  without  vocabulary  analogy?  2)  Is  there  a significant difference in the reading comprehension between the control and experimental groups based on the pre-test and post-test results? A test was conducted for control and experimental groups before and after the treatment process. T-test was computed to reveal whether there was a significant  difference in  the pre-test  and post-test results of the control and experimental groups. Findings of the research were: 1) The use of vocabulary analogy improved students’ reading comprehension 2) The computed T value based from the results of pre-test in the control and experimental groups is 0.130,  lower  than  T  tabular  value  of  1.996.  This  result  accepts  the  null hypothesis that there is no significant difference in the results of pre-test of control and experimental groups. Moreover, treatments were given to control and experimental groups after the pre-test, control group was taught without vocabulary analogy and experimental group was taught with vocabulary analogy before the post-test for each group. The computed T value in the post-test of the control and experimental groups is 11.15, higher than T tabular value of 1.996 at5% level significance. This result rejects the null hypothesis that there is no significant difference in the results of pre-test and post-test of control and experimental groups. Based on findings, the following conclusions were drawn: 1) The use of vocabulary  analogy  had  significantly  influenced  students’  reading comprehension particularly of the experimental group 2) There is significant difference in the post-test results of the control and experimental groups. Null hypothesis was rejected since the computed T value was higher than the T tabular value.

The aim of this study is to examine the effects of 6-week Zumba exercises on flexibility, leg strength, back strength and muscular endurance parameters in women aged 25-45. The research group consists of a total of (n=20) women, (n=10) in the experimental group and (n=10) in the control group, between the ages of 25-45 living in Istanbul. The participants in the experimental group were given 60 minutes of Zumba exercises 3 days a week for 6 weeks, and sit-reach, 1-minute sit-up and strength test measurements were made to the participants before and after the exercise program. Participants in the control group were not included in any exercise program. As a result of the analysis, it was determined that there was a statistically significant difference between the participants' flexibility, leg strength, back strength and muscular endurance values between the pre-test and post-test within the group (p< 0.05). In addition, there was no significant difference between the pre-test and post-test values between the groups (p< 0.05). In conclusion; It was determined that zumba exercises applied to the experimental group did not have a significant effect on flexibility, muscular endurance and back strength. In the leg strength parameter, the effect of zumba exercises applied to the experimental group on leg strength was found to be significant at a rate of 34%. In the light of these data, it was concluded that zumba exercises performed in sedentary women have a positive effect on lower extremity strength.

The learning assessment centre helps managers define learning objectives based on feedback in a group of peers. This study tested the hypothesis that the centre empowers managers to cope with change. Statistical methodology for a pre-test, post-test design using ordinal (Likert) data is also reviewed. Middle managers from a bank undergoing major reorganisation were divided into two matched groups. The experimental group spent three days in a learning assessment centre designed to give them self-insight and an understanding of the bank's requirements during the transformation. The control group received no treatment. Both groups were measured before and after the centre on a self-report measure and completed a peer assessment questionnaire completed by subordinates. Fifty-eight managers completed both pre-test and post-test measures. Whilst the subordinates of the control group reported a drop in their managers' empowerment, the subordinates of the experimental group reported a substantial improvement in their managers' empowerment. The difference between the groups was significant for five of the six areas measured. The difference between the self-reported performance of the two groups of managers was significant for only one area. These findings suggest that the learning centre could provide a solution to companies faced with the potentially destructive impact of major transition on management effectiveness.

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

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.

Rotation Model

Station rotation model has recently become a promising innovation in education in which learners lead to deeper learning and problem-solving development (Jones, 2018). The study determined the effectiveness of station rotation model with ICT integration to enhance the problem solving skill of ninth grade students of ARMM Regional Science High School during five weeks of intervention. The data of this study were obtained from the pre-test and post-test with open-ended questions from Control and Experimental Groups. These tests were administered before and after the intervention and scored using rubric. Moreover, attitude test was answered by the students to provide feedbacks on the use of station rotation model with ICT integration. Results revealed that there is no significant difference in the post-test performances under the Control Group (K-12 teaching instruction) and the Experimental Group (SRM with ICT Integration), t (25) =-1.324, p=.197. At the end of the study, experimental group under station rotation model with ICT integration does not significantly enhance students’ problem solving skill in Physics.

This research aims to determine how the effect of combination of Moringa Leaf consumption with aerobic exercise against VO2Max and Lactate Threshold as ergogenic aids. 16 Taekwondo athletes are participated in this research. Participants are divided into 2 groups: the experimental group, which has been given the treatment of Moringa leaves and aerobic exercise, and the control group, which has been given an aerobic treatment only. The method used is experimental method with randomized pretest-posttest comparison group design. This research took 6 weeks length with aerobic exercise 4 days a week. Moringa leaves consumed at a dose of 2000mg during treatment. The data collection used a Balke Test to measure the VO2max and modified Conconi Test to measure the lactate threshold. The results of this research showed a significant increase in mean before and after treatment in both variables from each group (p <0.05). However, the value of the increase in both variables between the two groups did not show significant difference (p> 0.05). These results, it can be concluded that there is a significant increase of VO2Max and Lactate Threshold between pre test and post test in each group, but there is no significant difference from deviation of increase of between control and experiment group although the experimental group increase is higher than the control group.

This study aimed to find out if Physics Education Technology (PhET) simulations can improve the performance of the Baybay City Senior High School STEM students on the selected topic in physics, that is, electrodynamics. This study utilized a quasi-experimental type where pre-test and post-test are multiple choice type of test and involved 72 STEM students. The grouping of the students was identified based on their sections, one section served as the control group and other is the experimental group. Experimental group is allowed to play the PhET simulation for an hour utilizing their vacant period every day, while the control is not exposed to any activity that intervene leading to the creation of formal construct of ideas in electrodynamics. Result showed that mean scores of the control and experimental groups does not imply a significant difference, despite of the interest shown by the students in playing the said simulation. Perhaps, students are more attracted to simulation in which they have gone through during their lectures. Furthermore, study shows that the performance of students before and after exposure to PhET simulation does not necessarily pose a big difference but indicates a slight improvement to their performances.
