For better or worse, our university’s school of engineering assumes that most (if not all) incoming students should begin with Calculus II. In addition, there is an increasing number of students who begin their college math with multi-variable calculus. In the Fall 2017 semester, less than 15% of our incoming students began with Calculus I. As a result of this trend away from Calculus I, most of our degree programs now assume that students complete calculus by the end of their first year. Unfortunately, much of the second year schedule is structured around this assumption, which can create difficulties for students that took Calculus I in the fall semester of the previous year. (Note that these students must take three semesters of calculus and are therefore unable to complete the calculus requirement by the end of their first year.) These systemic forces result in an unhealthy dynamic that generates many negative feelings and poor decisions: (1) incoming students that enroll in Calculus I are often afraid of falling behind their peers, while (2) many incoming students that struggle with Calculus II won’t move to Calculus I because they’re also afraid of falling behind.
It’s our opinion that many more of our students would benefit from beginning with Calculus I rather than Calculus II. Unfortunately, this isn’t likely to happen any time soon, for many of the reasons described above. As a consequence, we’ve responded to the problem by developing a new two-semester sequence for students that should begin with Calculus I. We hope to eliminate worries/pressures related to “falling behind their peers” and even some of the stigma that students can sometimes feel. (Engineering school can be a very competitive place!)
This new sequence includes the most essential elements of single-variable and multi-variable calculus. We’ve kept many topics often skipped in high school (e.g., hyperbolic trigonometric functions, related rates, optimization, Newton’s method, work, force of a fluid), but we’ve also “trimmed the fat” by eliminating some less essential topics (e.g., trigonometric substitution). In addition, many topics have been stream-lined. For example, our coverage of trigonometric integrals has been reduced to the forms they will encounter most in their future engineering courses, and we cover infinite series with a focus on applications of power series rather than covering each and every convergence test  .
This is the second step in a three-year plan to redesign our calculus sequence. Ultimately, we hope to develop three tracks which target engineering students of different skill levels. The advanced track was launched in 2016-2017, and our preliminary results were reported at the 2017 ASEE conference . As an ongoing project, we continue to investigate the impact of the redesign on student learning. In this paper, we will present the main features of the implementation of this new track and examine some preliminary results. This will include a comparison of student performance in all three tracks relative to their performance on an initial assessment of their pre-calculus preparation. Furthermore, the changes and improvements made for the advanced track will also be discussed.
