ABSTRACT
This study examined the level of conceptual understanding in solving stoichiometric
problems in class X chemistry under Trashigang District, Bhutan. In particular, this study
examines the perceptions of teachers and students about conceptual understanding and
algorithmic skills in stoichiometry. In addition, the study also examined the impeding factors
in conceptual understanding and the relationship between students’ ability to solve
stoichiometric problems using conceptual understanding and algorithmic skills. The study
employed a convergent parallel mixed methods design, which allows the collection of
quantitative and qualitative data simultaneously. The target population comprised two
hundred fifteen students and three chemistry teachers from three secondary schools. The
research tools included a Stoichiometry Achievement Test for students and semi-structured
interviews for teachers and students. Despite a strong positive correlation between conceptual
understanding and algorithmic skills in solving stoichiometric problems, 71.16% of students
showed higher algorithmic skills with lower conceptual understanding in the achievement
test, suggesting that conceptual understanding was low in solving stoichiometric problems.
