46 students took an exam with 50% multiple choice and 50% written. A t test showed no significant different between the grades from the 2 question types. Linear regression analysis showed an R squared value of .6. A student getting -8 on the MC, was likely to get close to a -8 on the written. This suggests to me that test preparation is more important than the type of question asked, but written portions will encourage additional development of writing skills.
Not all faculty have the time or nor want to teach in the calculus/physics learning community. So, how do we help faculty who teach stand alone calculus courses? Also, stand alone calculus courses do not have another instructor present to help emphasize concepts. So, Becky is teaching a stand alone calculus course in Fall 18 to see if she can cut down on some competencies, incorporate labs, and she will compare her course to other instructors who teach non-learning community calculus courses. Did Becky's class perform the same, worse or better on the common final? If worse, why?
The purpose of this CATS is to document a qualitative review on my experience in the 2nd semester calculus/physics learning community (MAT231/PHY131). Second semester physics covers charges, electric and magnetic fields, circuits, current (etc), and these concepts have been quite difficult for me to grasp and tie into calculus without Dwain’s help. The attached narrative provides my previous experiences, current experience, and plan for the future .
Need: Streamline 1st 4 weeks of Differential Equations. Create clearer expectations, journal instructions, MATLAB directions, problem sets, and activities. Alleviate student confusion.
This CATS' purpose was to determine if part of an ACC230 exam resulted in a statistically significant difference between an onine course and a F2F course. In Fall of 2017, I piloted an ACC230 online class. I wondered if there would be a major grade/score difference on an Inventory Valuation problem using First-In-First-Out (FIFO) and Last-In-First-Out (LIFO) between the two, different, instructional modalities. I picked this accounting topic because it was used in two prior CATS (candy example). My hypothesis was that online students would score lower, because learning accounting online
Introductory Chemistry (CHM130) instructors have been using a pre/post test at the beginning and end of the semester in the hope of using the data to determine how conceptual understanding changes as a result of instruction. The original test was not personalized to the curriculum with several topics not even addressed and as a result it was insufficient for detecting student misconceptions. A new Concept Inventory (EMCCi) was developed, thanks to an EMCC learning grant, that was personalized to the CHM130 curriculum.
For many years now, physics/chemistry faculty require students to journal after each class period (note: there are other faculty on campus who have been journaling for years, as well). In Fall 2017, a few non-phy/chem faculty incorporated journaling in their classrooms for the first time. In Spring 2018, during week of accountability, approximately 15 instructors met and discussed best practices in journaling.
Statistics elicit overall student angst, which affects grades, attitude, attrition and learning. Although students attended tutoring, were allowed to re-do homework and engaged in interactive classroom experiences, PSY 230 course retention rate remained at 25%. I used a different pedagogical technique this semester - Mastery Learning - which was used successfully in K-12 grades. Rather than a traditional letter grade or percentage on assignments, students received "not yet" grades and instructor feedback. Resubmissions were accepted as many times as necessary to reach mastery.
A prerequisite to physics is MAT182. Students need to know law of sine/cosine, and vector concepts from trig to be successful in physics. In the past, I would spend a lot of time classify triangles (SSS, ASA, etc) to help students know which "law" to use, and this was done at the end of the semester. I did not spend time using law of sine/cosine with vector applications . Students typically scored a low B on law of sine/cosine problems. In F17, I taught the "laws" and incorporated vectors in week 4 to show students real life applications.
Several years ago, Holly Dison, math faculty, found a calculus concept pre-post test to give in our MAT22X courses. This pre-post exam was copyrighted by another college, but approval was given to use it in our classes as long as we did not share the results with anyone. The exam consisted of 22 multiple choice questions. Each question is designed to see if students understand the CONCEPT; the problems are not procedural. Each multiple choice option is designed to be common misconceptions.
