Calculus is typically one of the first college courses encountered by science, technology, engineering, and mathematics (STEM) majors. Calculus often presents major challenges affecting STEM student persistence, particularly for students from groups historically underrepresented in STEM. For life sciences majors, calculus courses may not offer content that is relevant to biological systems or connect with students' interests in biology. We developed a transformative approach to teaching college-level math, using a dynamical systems perspective that focuses first on demonstrating why students need math to understand living systems, followed by providing quantitative and computational skills, including concepts from calculus, that students need to build and analyze mathematical models representing these systems. We found that students who complete these new math courses perform better in subsequent science courses than their counterparts who take traditional calculus courses. We also provide evidence that the new math curriculum positively impacts students' academic performance, with data that show narrowing of the achievement gap, based on students' math grades, between student subgroups in the new math courses. Moreover, our results indicate that students' interest in the concepts and skills critical to the quantitative preparation of 21st-century life sciences majors increases after completing the new contextualized math curriculum.
微积分通常是科学、技术、工程和数学(STEM)专业学生首先接触到的大学课程之一。微积分通常会带来重大挑战,影响 STEM 学生的坚持度,尤其是对历史上代表性不足的 STEM 群体的学生。对于生命科学专业的学生来说,微积分课程可能没有提供与生物系统相关的内容,也无法与学生对生物学的兴趣产生联系。我们开发了一种变革性的大学数学教学方法,采用动态系统的视角,首先强调为什么学生需要数学来理解生命系统,然后提供定量和计算技能,包括微积分的概念,这些是学生构建和分析代表这些系统的数学模型所需的。我们发现,完成这些新数学课程的学生在后续的科学课程中的表现优于那些修传统微积分课程的学生。我们还提供了证据表明,新的数学课程对学生的学业成绩产生了积极影响,数据显示,根据学生的数学成绩,新数学课程中学生群体之间的成绩差距缩小。此外,我们的结果表明,学生对 21 世纪生命科学专业定量准备至关重要的概念和技能的兴趣在完成新的情境化数学课程后有所增加。
