<p><em>This paper describes some activities that the author has designed using Project Based Learning (PBL) to develop students’ understanding of statistics. This study used a quasi-experimental method with a one group pretest-posttest quantitative research design. The subjects in this study are 30 students of class VII in SMP Negeri 6, Surabaya, Indonesia. The data collected using a questionnaire and a test. The validity of students’ response used product-moment correlations and the reliability test used the Cronbach’s Alpha formula, and the hypothesis was tested using the t-test (one sample t-test). The results showed that the positive response of students using PBL design to expand mathematics students’ understanding of statistics, namely 85.83%. Furthermore, there was a difference in the students’ learning outcomes before and after they learned through the PBL learning design, indicated by pretest the mean of score is 38.30 and a posttest mean score is 67.17. Besides that, t<sub>observed</sub> of pretest is 15.931 and t<sub>observed</sub> of posttest is 34.655, both are greater than t<sub>table</sub> with a significant level ?=0.05 is 2.042. Thus, we could be concludes that there as a difference the understanding of statistics students’ outcome before and after learning with PBL design.</em></p>

The Difference

Background: The important aspect for child especially children with mental retardation is oral health. Children with mental retardation have limitations in motoric activities that relate to the actions of dental hygiene in normally, that activities is toothbrushing and it can do by bass and horizontal method. The aim of this study is to know the difference effectiveness toothbrushing with bass and horizontal method on the changed of plaque index in children with mental retardation. Method: The quasi experimental methods with non-equivalent group design with post test design was used in this research and have done on 24 children with mild mental retardation at SDLB Purwosari Kudus which divided two groups, 12 students brushing with bass method and 12 students brushing with horizontal method. Result: The data were tested with paired t-test to compare plaque index before and after toothbrushing with bass and horizontal method, showed that there were meaningful differences (p<0,05). Independent t-test to compare the changed of plaque index between both methods, showed that there were no meaningful differences (p>0,05). Conclusion: It concluded that both bass and horizontal method effectively on the changed of plaque index in children with mental retardation. There was no difference effectiveness between both methods.

Dentifrices used to aid plaque removal from dental surfaces and gums while teeth brushing. Propolis is one of bee products that can be added into dentifrices and its property is to inhibit plaque-forming bacteria growth. The main objective of this study was to rule out any plaque index differences before and after teeth brushing with and without propolis contained dentifrices. It was a quasi-experimental research with the single blind-parallel method. Subjects were 30 students from 33 Junior High School Bandung aged 11-13 years old, collected by purposive sampling technique. Subjects divided into groups which using propolis and without propolis dentifrices, teeth brushing. The plaque was assessed using the Patient Hygiene Performance (PHP) Index from Podsadley and Haley. Data collected would be tested using the paired t-test and independent t-test. This study concluded that there was a difference of plaque index before and after teeth brushing with and without propolis contained dentifrice. Indeed, the propolis contained dentifrice less much decrease the plaque index compared to the without propolis contained dentifrice.

The aim of this study was to know the effectiveness of the use of alphabet cards game as interesting tool to explain vocabularies and it make it easier to remember their meanings. This study belongs to the quasi experimental research and presents pre-test, post test and to investigate the effect of using alphabet cards game on vocabulary mastery of commercial business administration students. The participants were the students from commercial business administration students at the third semester (N=54) of State Polytechnic Bengkalis and divided into two groups. Both groups were taught vocabulary, however, the experimental group students who are exposed to alphabet cards game and the controlled group students who received conventional method. Pre-test and post-test were given to both experimental group students and controlled group students. The score of the vocabulary tests were compared through independent sample t-test. The mean value of pre-test of experimental class was 61.35, while the control class was 52.23. After learning using alphabet card games in experimental class the mean value obtained in post-test was 78.85, while in control class was 59.04.  The improved of learning outcomes can be seen from the level of significance was 0.000 and it was lower than t test 0.000<0.05.  It means that the hypothesis null is not accepted. Therefore, it can be concluded that the score of the students in learning vocabulary between the experimental group and control group was significantly different. The experimental group students who learned vocabulary using alphabet cards game had increased their vocabulary mastery.

This study tried find the students’ improvement in listening achievement after having taught by using the shadowing technique. The method used was a quasi-experimental that involved two groups, namely the control group and experimental group. The population of this study was all the tenth graders of SMA Negeri 3 Unggulan Kayuagung with a total number of 198 tenth graders. Purposive sampling method was applied to select the sample involved 72 tenth graders. In collecting the data, try out the test was used to get the desirable questions that would be used in the pretest and posttest to both groups in the control and experimental group. To verify the hypothesis, the normality and homogeneity of the data were firstly analyzed before being continued to be analyzed by using a t-test. Based on the result of data analysis in an independent sample t-test, there were some findings found. First, the mean score of a posttest (75.56) in the experimental group was higher than the pretest (69.03) in the control group. Secondly, the value of tobtained was 2.77 at the significant level of p<0.05 in two-tailed testing with df = 70, the critical value of ttable was 1.99. Since the value of tobtained was higher than ttable, the null hypothesis (Ho) was rejected and the research hypothesis was accepted. In conclusion, it showed that the shadowing technique could improve the tenth-grade students’ listening achievement at SMA Negeri 3 Unggulan Kayuagung.
