This study aims to investigate an intervention in the application of the Butterfly Method Algorithm with the Bar Model Concept on the addition and subtractions of Fractions to Year 9 students in one of the Government secondary schools in Brunei Darussalam. The Butterfly Method is an alternative visual method for teaching fractions where the diagonal and horizontal multiplication of the denominators and numerators are employed by drawing the Butterfly. A mixed-method approach was used to explore the impact of the intervention with data gathered from the students’ written pre- and post-tests and interview transcripts. The tests conducted before and after the intervention were used to analyze students’ errors and misconceptions. The students’ written analyses of the post-test results revealed that not all of the students applied the Butterfly Method. A few students were selected for interviews in order to gain deeper insights into how they developed the errors and misconceptions from both tests. Findings from the students’ interview transcripts revealed they were not confident with the Butterfly Method, and they needed more time to be familiar with the concept. Another factor for not applying the Butterfly Method is due to students’ confusion on subtracting fractions that has the same denominators as well as subtracting a proper fraction from a whole number. This study concluded that students who applied the Butterfly Method helped them to remember the new method from the intervention satisfactorily in comparison to those who lack the confidence in applying it.

Mouthwash is an additional mechanical oral cavity cleaning method which is known to reduce oral bacterias that causes plaque build ups. Mouthwash may and may not contain alcohol. The objective of this study was to determine the alterations on the oral cavity environment (salivary pH and plaque index) before and after gargling with alcohol and non-alcohol mouthwash, and to analyze which of the mouthwash is more effective. This study was an experimental study with one group pre test and post test experimental design. The subject of this study was 16 of University of Sumatera Utara’s female undergraduates whose age ranges from 18–23 years old and accorded to the inclusion and exclusion criteria. Subjects were divided in two groups, subjects were instructed to used the mouthwash twice a day for seven days, then salivary pH and plaque index were measured at third and seventh day of used. Repeated Annova test results shown a significant decreas on salivary pH and plaque index after gargled with mouthwash containing alcohol, in the non-alcohol mouthwash there was a significant decreased in plaque index but none on the salivary pH. Dependent T-test results shown that there were no difference in salivary pH and plaque index after gargled with alcohol containing and non-alcohol mouthwash. This study shows that non-alcohol mouthwash is better because there were a significant decrease in plaque index, without caused significant decreases in pH scores.
