This study investigated the comparative effectiveness of pedagogical pattern of running a course and talk-chalk methods on senior secondary school students’ achievement in waves. It is triggered by reports of persistent students’ low achievement in physics contributed largely by students’ poor performance in waves-related items. It adopted the quasi-experimental pretest-posttest control group design. Three research questions and hypotheses guided the study. There were 216 students who participated in the study. Physics Achievement Test (PAT) containing 50 multiple-choice researcher-developed items were used as instrument for data collection. Mean and standard deviation were used to answer the research questions while ANCOVA was used to test the hypotheses at 0.05 level of significance. Results showed that: the pedagogical pattern of running a course method was superior method in fostering students’ achievement in waves; female students achieved higher than male students using pedagogical pattern of running a course strategy to teach waves; and there was no significant interaction effect of teaching methods and gender on students’ achievement in waves. From the findings, it was recommended that the pedagogical pattern of running a course strategy should be used in teaching physics in secondary school education system and in training of teachers.

With the increasing technological and electronic development, methods have been developed to hide important information using text steganography as a new technology, since it is not noticeable and easy to send and receive. The use of the Arabic language is one of the new methods used to hide data. In this work, we preview our method that depends to use the part of Arabic language properties to embed the secret English message in to cover text to create text steganography. More than half of the Arabic characters contain dots. Several characters have upper dots and others have lower dots. Some have one dot others have two dots. Few have even three dots. In this new idea, we will use the dots of charters to embed the English secret message. First, we will compress the secret message by using the 5-Bit Encoding (T-5BE) to make the cover text able to embed more bits of the secret message by 37.5%. Then we start using the Arabic semantic dictionary to correct the hiding path and enhancement the stego-cover text to eliminate errors caused by switching words. In this research, we were able to extract experimental results that show that the proposed model achieves high masking accuracy in addition to the storage capacity of the cover text.

The intensity of cigarette exposure is associated with the severity of the inflammatory reaction. Treg cell plays a role in suppressing the inflammatory response. There has been no clear evidence on the relationship between smoker behavior with the nicotine level and Treg number. We will investigate the relationship between smoking behavior with the nicotine level and Treg number. We conducted a cross-sectional study of 106 healthy volunteers in Yogyakarta. We interviewed the subjects and took their blood samples for hemogram, Treg number, nicotine level, and blood chemistry examination. The inclusion criteria were fit, male or female, aged 18 years or older, and willing to volunteer proven by completing and signing the informed consent. We collected the data on smoking habits through interviews guided by a questionnaire. We examined hemogram and blood chemistry using a spectrophotometer, while the levels of nicotine were measured using The enzyme-linked immunosorbent assay (ELISA). We described the characteristics of the subjects by univariate analysis. The bivariate analysis was to determine the relationship between cigarette smoking length with nicotine level and Treg number. The results show a connection between the range of tobacco and cigarette number with nicotine levels in the blood with a value of r=0.63 in the Pearson correlation test p<0.00. It can be concluded that there is a relationship between behavior smoking with nicotine levels and Treg counts.

In this study, breast cancer prediction model is proposed with decision tree and adaptive boosting (Adboost). Furthermore, an extensive experimental evaluation of the predictive performance of the proposed model is conducted. The study is conducted on breast cancer dataset collected form the kaggle data repository. The dataset consists of 569 observations of which the 212 or 37.25% are benign or breast cancer negative and 62.74% are malignant or breast cancer positive. The class distribution shows that, the dataset is highly imbalanced and a learning algorithm such as decision tree is biased to the benign observation and results in poor performance on predicting the malignant observation. To improve the performance of the decision tree on the malignant observation, boosting algorithm namely, the adaptive boosting is employed. Finally, the predictive performance of the decision tree and adaptive boosting is analyzed. The analysis on predictive performance of the model on the kaggle breast cancer data repository shows that, adaptive boosting has 92.53% accuracy and the accuracy of decision tree is 88.80%, Overall, the adaboost algorithm performed better than decision tree.

The purpose of this study was to explore the use of reflective practice by English language teachers in providing effective English language teaching in primary school classrooms. This qualitative case study involving six in-service English language teachers who were selected based on purposive sampling. The data in this study were collected using teachers’ reflection logs and a series of semi-structured interviews with the English language teachers. Thematic analysis was used to identify emerging themes based on the codes gathered from the interviews and teachers’ reflections logs. The results showed that the English language teachers used reflective practice erstwhile in preparing and providing effective English language teaching for the students. They reviewed what has been accomplished and identify constructive guidelines to follow to succeed in the future teaching. They have also been doing variations of changes in teaching based on reflecting on the quality of instruction, levels of instruction, using incentive to motivate the students and managing time equally in teaching and learning process to help the children in learning English language. Since there is no clear guideline for teachers who use reflective practice in their classes, this study provided some insights on the preparations and the use of reflective practice as part of their teaching and learning process.
