Studies on student learning of scientific concepts have shown that students often
experience various difficulties in understanding basic physics concepts such as
vector quantities, as a result of formal and informal learning. The purpose of
the present study is to document Grade 11 students’ difficulties in
understanding vectors and their associated concepts. Specifically, the study
tried to find answers to questions about the overall level of difficulty
experienced by Grade 11 students about vectors, the nature of these
difficulties, and their association with operations, such as scalars, adding
vectors graphically, determining vector magnitude and direction, and multiplying
vectors by numbers. Altogether, 58 Grade 11 students participated in this study.
The study employed a specifically adapted test to assess participants’
understanding of vectors in relation to: (1) identifying whether students can
distinguish between vectors and scalars, (2) adding vectors graphically, (3)
determining the vector magnitude and direction, and (4) multiplying vectors by
numbers. The findings suggested that, although most students were able to
distinguish between vectors and scalars, they had experienced various
difficulties in understanding operations in relation to adding vectors,
graphically and mathematically, determining vector magnitudes and directions,
and multiplying vectors by numbers. The findings were discussed within the
recent UAE educational reform policy.
