Abstract

As one of the mathematical mnemonic tactics that use a visual approach, the Onion Skin Method (OSM) compares the structure of an onion to that of a mathematical problem. The study aimed to determine, through pre-and post-testing, the influence of incorporating the OSM into the learning of solving basic linear equations. The sample involved two Year 10 classes consisting of 31 students. Using a paired t-test, the study demonstrated a considerable improvement in students’ ability to solve linear equations. A semi-structured interview with six students was done to examine their perceptions. Five themes were derived from the interviews: the time spent by students to solve simple linear equations, students’ reactions to their performance on the post-test, students’ preferred method for solving linear equations, students’ perception of the OSM, and students’ future use of the OSM. The findings indicated that the OSM accommodates the learning styles of the participants, which predominantly employ mnemonic strategies. This research may inspire teachers to use alternative methods when instructing students on solving fundamental linear equations, allowing them to modify their instruction or develop more practical lessons for teaching.

Abstract

This experimental case-study examined the performance of convenient sampling of fourty-five Year 9 students in solving word problems involving percentage from two classes in one government secondary school in Brunei Darussalam, using Bar Model as a solving strategy. Data was gathered quantitatively through written tests in the form of six word problem items as pre-test and post-test.  The mean score of the pre-test was 0.93 indicating that the performance of the participating Year 9 students in solving word problems involving percentage was low prior to intervention. Intervention lessons produced a gain in the post-test mean to 2.87.  Although the mean of post-test marks is still lower than the passing mark of the test, paired-sample t-test provided evidence of significance, thus proving that Bar Model Method had positive effect to the performance of word problem involving percentage. Evidence also indicated an increase in the students’ overall marks  from pre-test to post-test, with almost all except two students failed the pre-test to twenty-six students achieving marks above passing mark of 3 in post-test.  Item-by-item analysis showed increase in correct responses in every item in post-test, even those with no attempts in pre-test.  These provided further evidence that there is overall improvement in students’ performance in word problems related to percentage after the use of Bar Model as intervention.

Abstract

The science show is a form of informal science learning (ISL) that can potentially develop students' interest in science. However, there needs to be a gap in bridging the ISL elements, such as science shows, into formal teacher education programs as one innovative pedagogical approach. Thus, this study investigates how secondary science teacher candidates' perceptions of science displays shifted after carrying out their science shows and explores their shared experiences as part of their teacher training program. Data were collected from 16 secondary science teacher candidates of cohort 2020 based on their written reflections on their experiences before, during, and after conducting science shows. The study found that some science teacher candidates' perceptions of science shows had shifted, and the others had remained the same. The science teacher candidates' everyday experiences during the science show implementation were their effort to conduct a successful demonstration and develop video-making skills.
