This study determined the effectiveness of synectics in teaching Grade 9 science in one private high school in Mandaue City, Cebu. A quasi-experimental design using the control and experimental groups was utilized. The experimental group was taught science concepts using synectics, while the lecture method was used in teaching the control group. Pretest and posttest evaluations were utilized to measure the academic performance of both groups of students. The results of the study showed that the pretest scores of the control and experimental groups on the three topics covered were fair and that the pretest mean values for the two groups were comparable or closer with each other. It also revealed that the posttest scores of both groups marked an increase in good performance level and the posttest mean value of the group with an intervention using synectics in teaching was greatly or highly improved compared to the group taught using the lecture method. The results also showed that there was a significant difference in the pretest and posttest scores between the control and experimental groups. Using synectics in teaching science concepts is an effective technique in improving students ‘performance since it provides them with a meaningful and authentic understanding of scientific concepts by associating these concepts to real-life situations.

The quest for better strategies in teaching is a never-ending process. This scenario is heightened more by the myriad online instructional materials fit for classroom use. The study aimed to determine the effectiveness of video lecture materials for statistics proficiency of first year students of Davao Doctors College.The researchers employed quasi-experimental design that involved purposively chosen 31 students for the control group and 26 students for the experimental group. The control group received traditional instruction while the experimental group utilized video lecture materials as the instructional tool. The questionnaire consisted 50 multiple choice items and established a reliability index of .82. This investigation used t-test analysis to establish the same level of statistics proficiency among the students before the conduct of the study. The study concluded that both learning strategies were effective in teaching students the basic concepts of statistics as indicated by the significant improvement of their pre-test to posttest scores. Although the posttest results of the students who were taught using video lecture materials were higher than those supervised using lecture method, the significance of this difference was never established. Thus, the use of video learning material as an instructional tool in statistics is equally effective with the traditional lecture method. Keywords - Mathematics education, video lecture material, effectiveness, statisticsproficiency, quasi-experimental design, significant difference, t-test, Philippines

BACKGROUND: The recent epidemiological and experimental evidence suggest possible antioxidant effect of carbocysteine in patients with chronic obstructive pulmonary disease (COPD).AIM: To assess efficacy and tolerability of carbocysteine in the management of stable COPD.METHODS: We performed an observational, non-randomized, open study (a real life study) including 87 patients with stable COPD (group B and D by combined COPD assessment) divided in two groups, examined group (EG) and control group (CG). All participants were treated with the regular treatment of the stable disease, but in the participants of the EG carbocysteine 1,500 mg daily was added to their regular treatment during the period of two months. The study protocol included completion of the COPD Assessment Test (CAT) and spirometric measurements at initial visit and at the end of the mentioned period.RESULTS: We found significantly lower mean value of the overall CAT score in the EG at the end of the study as compared to its mean value registered at initial visit (26.9 vs. 24.3; P = 0.007). In regard to certain CAT items, we found significantly lower values of the mean scores related to cough phlegm and sleep disturbances as compared to their mean scores at initial visit. In addition, the mean values of the overall CAT scores at initial visit and at the end of the study in controls were similar. In EG we found significantly higher mean value of the MEF 25-75 at the end of the study as compared to its mean value registered at initial visit (59.3% vs. 67.2%; P = 0.003). There was no significant difference in the mean values of other spirometric parameters at the end of the study as compared to their mean values at initial visit. In controls we registered similar values of all measured spirometric parameters at the end of the study as compared to their values registered at initial visit. Mild gastrointestinal manifestations were registered in 13.3% of the participants of the EG during the examined period.CONCLUSION: Our findings indicate positive effects of carbocysteine regarding the symptoms and lung function, as well as its good tolerability in the patients with stable COPD.

AbstractThis quasi-experimental study investigated the effect of teaching aesthetic skills to faculty members on development of their effective teaching performance through a two-group pretest-posttest design. The sample included 32 faculty members at a major Iranian university who were divided into the experimental (11 participants) and control groups (21 participants). The experimental group was taught to use aesthetic skills in the teaching and learning processes; however, no intervention was applied to the control group. To evaluate the effective teaching performance of the faculty members, a tailor-made questionnaire was used in two pretest and posttest stages, where randomly chosen students were asked to express their opinions about the faculty membersí performance. The sample size of the students was 1096 in the pretest stage and 935 in the posttest stage. Paired t-test results showed that there was no significant difference between the mean effective teaching scores of the faculty members in the control group in the pretest stage and in the posttest stage. However, the mean effective teaching scores of the faculty members in the experimental group were found to be significantly higher in the posttest. In addition, although there was no significant difference between the mean effective teaching scores of the two faculty groups in the pretest, faculty members in the experimental group outperformed their counterparts in the control group. Based on the findings, applying aesthetic skills by faculty members in the teaching and learning processes can pave the way for sustainable development of their effective teaching performance. Therefore, faculty members are recommended to acquire the required knowledge and skills to better use aesthetic skills in the teaching process.

One of the factors that influence Kadarzi's achievement is the knowledge and attitudes of the toddler's mother. This study aims to determine the effect of counseling using backsheet media on the knowledge and attitudes of toddlers' mothers about Kadarzi in the Cipeundeuy Health Center District of West Bandung Regency. The research design used was quasi-experimental with a pre-post test control group design model with a total sample of 28 people each for the experimental group and the control group. The experimental group was given an intervention in the form of counseling using flipchart media, while the control group was given an intervention in the form of counseling using leaflet media. The results obtained from the Wilcoxon test in the experimental group and the t-dependent test in the control group were changes in the increase in knowledge and attitude scores in the experimental group and the control group after intervention (p <0.005). The results of the Mann-Whitney test showed no significant difference between knowledge and attitude scores in the experimental group and the control group (p> 0.005). It is better to do further research related to Kadarzi's behavior so that the application of the Kadarzi indicator can be monitored so that it can describe the results of attitudinal changes, and to increase Kadarzi's knowledge and attitudes to toddler mothers.

Background: Health problem are culturally associated with smoking in developing countries. Many hazardous chemicals are taken up by direct or passive smoking causing lipid peroxidation resulting in oxidative stress. Objectives: To estimate the occurrence of smoking and its effects on the lipid profile in populations of Hasilpur, Pakistan. Methodology: The current study was conducted from April - August 2014. Out of 247 apparently healthy subjects of both genders (male=220; female=27), 134 were smokers and 113 were non-smokers. In order to analyze lipid profile, blood samples were collected in early morning hours from the selected members who were asked to fast all night. By using Chem-100 chemistry analyzer, cholesterol, triglyceride, HDL, LDL and VLDL were analyzed. Results: The overall prevalence of smokers was 54.25%. The results showed 60.9% prevalence in males and 0% in females. The mean value of serum triglyceride in control, light smokers and heavy smokers was 147.4±11.7mg/dl, 190.8±41.4 and 205.3±29.7mg/dl, respectively. The results of cholesterol in control, light smokers and heavy smokers were 147.38±7.99mg/dl, 136.8 ±12. 8mg/dl and 173.44±8.63mg/dl, respectively. There was a considerable distinction in the mean level of serum triglyceride and cholesterol between the control group, light smokers and heavy smoker groups (P<00.5). The mean value of HDL of control, light smokers and heavy smokers was 30.93±1.30mg/dl, 31.10±2.45 and 34.58±1.55mg/dl, respectively. The mean values of LDL and VLDL of control, light smokers and heavy smokers were 110.46±3.63mg/dl, 106.00±4.52mg/dl, 117.19±3.48mg/dl and 33.54±3.11mg/dl, 49±9.02mg/dl, 41.06±5.34mg/dl, respectively. There was significant difference in the mean level of HDL, LDL and VLDL between the control group, light smokers and heavy smoker groups (P<0.05). Conclusion: This study concluded that smoking is the reasons of variation in the lipid profile. Elevated period of smoking and the number of smoked cigarettes/day reason the alteration in serum lipid levels and is probably related with increased danger for coronary artery disease.

Attitudes Towards Learning

A positive attitude correlates to successful learning; while a negative attitude leads to poor learning. The present study aimed to compare the pre-service biology teachers’ attitudes towards learning biology and assessing their attitudinal change before and after being taught by resource-based instructions (RBI) in Rwanda. A survey-research design was used, in combination with a quasi-experimental control group, and the equivalent time-series designs. Pre-service biology teachers were taught at a public university in three separate groups, with one control group and two experimental groups. Each group received a pre-attitude and a post-attitude assessment. In contrast, at a private university, they were taught as a single group, in a series of instructions, starting with the lecture method, followed by animation-based instruction and small- group laboratory activities, in which at each stage, the pre-service biology teachers received the same assessment. The biology Attitudinal Scale showed a Cronbach alpha reliability of 0.625 before its use. The data were analyzed quantitatively; and the results revealed no statistically significant difference between the public and the private pre-service teachers’ attitudes before learning microbiology. After the teaching interventions, the results revealed that both the traditional and the resource-based instructions improved the pre-service biology teachers’ attitudes towards learning biology, as a result of their improved maturity and their anticipated future teaching career.
