  Abstract: Sampling is an important scientific reasoning ability frequently used in experimental design and data interpretation. As part of the research on assessment of students' scientific reasoning skills, we designed a series of multiple-choice instruments that probe students' understanding of the concept of sampling. The assessment was carried out among the students from grade four to grade 11 to study the development of students' understanding about sampling which was involved in the scientific context. Results from students at different grade levels indicated that students did not understand and consider the concept of sampling as a significant scientific reasoning skill until grade eight.
