Implications of the chi-square test for independence are certainly favorable. Higher percentages of perfect scores on the limits and chain rule
assignments (summarized again in Figure 4) were attained during the Spring
2012 semester, the semester during which the just-in-time modules were the
only newly added content-specific components in the Calculus-I syllabus. All
other features related to course content during the Spring 2011 and Spring
2012 semesters, including the textbook, textbook assignments, online calculus assignments, syllabi, and number of exams were either identical or
very comparable. It is safe to conclude that the just-in-time tools certainly contributed positively towards significantly raising the number of students that
reach perfection on the limits and chain rule assignments
