Abstract
This study aims to assess the understanding of elementary school sixth graders on the tentativeness of scientific knowledge by using the revised NSKS. Answers to the following questions were sought in a survey: (1) Are there four factors that correspond to each of the four subscales? (2) Which statements did the elementary school sixth graders misunderstand? The revised NSKS was administered to 638 elementary school sixth graders. The instrument contains 24 statements with a Likert scale response format with three choices that include agree, neutral, and disagree. The subscales consist of four areas, namely creative, developmental, parsimonious, and testable. The results of the survey show that: (1) There are four factors that correspond to each of the four subscales; and (2) The sixth graders misunderstood the statement, "There is an effort in science to build as much as possible great laws and theories".
