Nature of Science Test (NOST) (Billeh & Hasan, 1975). This instrument consists of
60 multiple-choice items addressing the following components of NOS: Assumptions
of science (8 items), Products of science (22 items), Processes of science (25 items),
and Ethics of science (5 items). The test consists of two types of items. The first type
measures the individual’s knowledge of the assumptions and processes of science,
and the characteristics of scientific knowledge. The second type of question presents
situations that require the individual to make judgments in view of his/her
understanding of the nature of science. The major shortcoming of this instrument is
not its content, but rather, that no subscales exist. Thus, only a global or unitary
score can be calculated.
