Description: Our project aims to develop and test a calculus concept inventory while continuing our effort to implement and investigate the flipped classroom for calculus courses (MATH 150, 151 and 152). Students are not blank slates; instead, students bring with them often deep-seated preconceptions. Identifying the levels and types of the preconceptions of individual students is a critical first step to ensure the effectiveness of subsequent instruction.

A concept inventory (CI) is one of the tools that can be used to assess a learner鈥檚 understanding of fundamental concepts of a subject matter. A concept inventory is defined as a  designed to evaluate whether a student has an accurate working  of a specific set of concepts. Such a test can be used to assess students鈥� understanding of a subject matter鈥檚 fundamental concepts prior to instruction. This knowledge would guide subsequent instruction to address students鈥� preconceptions and allow measuring of learning gains at the end of instruction. Surprisingly, there is no well-established CI in wide use in calculus despite its foundational importance for many science and applied science disciplines. Additionally, the present best-known Calculus inventory uses the words such as 鈥渓imit鈥� and 鈥渄erivative鈥� which are fundamental concepts of calculus. Problematically, it is difficult to test students鈥� preconception of these concepts when they are explicitly referred to in the questions

We plan to engage in the challenging process of developing a CI for Calculus that does not make explicit reference to Calculus concepts. Such a tool would allow us, as well as others, to assess the students prior understanding of calculus concepts before they are introduced to the concepts through formal instruction.

Questions addressed:

• What previous work has been done to develop a calculus concept inventory (CCI)?
• What are the fundamental concepts that need to be assessed in a CCI?
• What test items need to be developed for each of the identified concepts in a CCI? What would these items and their answer options look like to reflect different levels of understanding? How can these options be best weighted to give partial credit/score?
• How can we begin to build and improve our CCI鈥檚 validity and reliability through pilot testing of the developed items in 麻豆视频first-year calculus courses?

Knowledge sharing: Dissemination will be done through discussing and sharing the instrument with the math department, via the Teaching Matters Seminar at SFU, and with colleagues who teach calculus at other institutions nationally and internationally. We also plan to present our initial results at the annual 麻豆视频Teaching and Learning Symposium and other local, national, and international conferences. Additionally, the development of the CCI can have wide application at other institutions nationally and internationally. It can contribute significantly to calculus assessment and teaching practices.
