In the revised curriculum 2017, computational thinking skills have been
integrated into the curriculum contents of all existing subjects in primary and
secondary schools in Malaysia. The newly revised curriculum calls for an
urgent need to prepare teachers to deliver computational thinking skills in
the classroom and assess the teaching and learning outcomes of
computational thinking skills. This paper reports the development of an
assessment rubric, myCTRubric, designed to evaluate the teaching and
learning outcomes of the newly integrated computational thinking skills
among primary school students in Malaysia. An action research approach
guided the design and development of myCTRubric. myCTRubric was
reviewed and validated by a panel of computational thinking subject matter
experts. Analyses of results show that myCTRubric is reliable and has strong
content validity. This pioneering work is expected to lend insights into the
teaching and learning practices of computational thinking in Malaysian
classrooms and served as a practical guideline for future research.
