1 | 2021 article | The reliability and usability perception of organic chemistry synthetic pathways board game Rajakumar Ramachandran This study aims to present the reliability and student’s usability perception of an educational board game in teaching and learning synthetic pathways at matriculation level. This board game mainly called as Synthetic Pathways of Organic Compounds (COPS). The research design used was ADDIE model. Needs analysis survey on 35 chemistry teachers and lecturers as well as previous literatures proved synthetic pathways and retrosynthetic reactions can be taught using game-based learning approach. Respondents for the research were one year matriculation program students from one of the colleges in Malaysia which was determined using two stage cluster sampling. Analysis of the usability perception data (mean score) shows students agreed on achieving learning goals (4.57) of organic chemistry synthetic pathways via COPS board game. Besides that, they also agreed on attractive board design (4.45), good board organisation (4.43), excellent playability (4.48) and high usability (4.48). Besides t..... 283 hits |
2 | 2022 thesis | Development of COPS board game on learning organic chemistry synthetic pathways among matriculation students Rajakumar Ramachandran This study aims to develop Synthetic Pathways of Organic Compounds (COPS) and
investigate matriculation students’ perceptions towards the board game. The research
employed the developmental design based on ADDIE model. A total of 171
respondents participated in this study where data were gathered via four types of
questionnaire. The needs analysis survey on 36 chemistry educators revealed 86.1% of
them required or had intention to use GBL in their organic chemistry lessons and 91.7%
agreed on suitability of GBL for the same purpose. After designing and developing
COPS, a questionnaire was administered among five experts whom averagely scored
90.8% of agreement on its validity. Pilot study on 30 respondents showed high
reliability coefficient (α = 0.993). One hundred and five matriculation students strongly
agreed that COPS has positive impact on learning organic synthetic pathways with high
mean scores for all the five constructs. Findings showed mean scores and standard
