The VOSI questionnaire elicits details of learners’ ideas of what scientists do in the production of valid scientific knowledge. Understanding about scientific inquiry is an integral component of scientific literacy, along with NOS. The VOSI is useful alone, or in combination with the VNOS to gain in-depth insights into respondent’s epistemological views of science. The VOSI targets aspects unique from, but complementary to, the VNOS instrument.

Probes personal beliefs about the nature of science within 3 scientific dimensions (structure, methodology, and validity of science) and learning science within 3 cognitive dimensions (learnability, reflective thinking, and personal relevance of science).
The inventory consists of eleven items, each representing a different skill in the science inquiry process. Youth are prompted to respond to each statement using a 4-point Likert scale indicating how often they practice each of the items when doing science: Never (1), sometimes (2), usually (3), and always (4). Recommended scoring of the SPSI is the calculation of a composite science process skills score. This is calculated by summing the individual ratings for each item. The score range for the composite score is 11-44.
