The effectiveness of concept mapping will be investigated in introductory chemistry students' achievement. The researcher will test the hypothesis which stated that the implementation of concept mapping in teaching introductory chemistry will increase students’' performance. The sample will be two sections, one will be the experimental group and another group will be the control group. Both groups had taken a pretest. The experimental group will draw concept maps for the units taught and will be part of their journal. The units will include naming, moles, balancing equation, stoichiome
Introductory Biology for Allied Health, Bio 156, is a course many students take for the nursing major. This course teaches a number of concepts that are important and repeated throughout other biology prerequisite courses (Bio 201 Anatomy and Physiology I, Bio 202 Anatomy and Physiology II, and Bio 205 Microbiology), nursing block 1-4 courses, and the NCLEX, nursing certification exam. The purpose of this CATS is to question whether the concepts we teach are retained through the courses. We decided to pick one topic and study this process.
Having now completed 3 semesters teaching BIO 182 - General Biology II for Science Majors, the area consistiently identified by student surveys as in need of improvement is the "Quality of the Textbook." The book is expensive (>$100), and yet, I have observed that many/ most students do not read the supplemental chapters that align with lectures / activities / labs unless I assign end-of-chapter comprehension questions. Following being awarded a FRACTYL grant last spring, I have been developing an OER, consisting of a series of engaging, supplemental videos that focus on case studies (
Chemistry students are required to think about the atomic nature of matter, while only being able to see the macroscopic level. To help them, we use particle (atomic) level diagrams that rely on different colors, shapes and lines to represent different types of particles, phases, reactions, and temperatures. These models are used throughout their chemistry courses particularly when systems become too complex to describe concisely in text or formulas. A firm grasp of understanding and drawing these diagrams is important for success in the future. However we never directly assess individu
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.
Students in microbiology struggle with osmosis - the movement of water in and out of cells according to solute content of the environment. This is covered in the pre-req course (BIO 156 or 181). Bio fac have articulated these concepts across the courses. Unfortunately for the last couple of years students were directed to skip the pre-req since HS bio counts. Usually osmosis is taught by introducing terms first then numbers (the conceptual piece) to describe the relative differences in solute concentrations internal and external to cells.
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
One of the biggest challenges for nursing students is to acclimate to the world of the nursing school exam. Gone are the days of one right answer, the nursing student must learn how to prioritize several correct answers to determine which is the "most" correct. During the Spring 2017, utilization of the Adaptive Quizzing/Learning Resources was highly encouraged but not attached to course points. In Fall of 2017, the Adaptive Learning activities were attached to 39 of the 600 total course points, leading to a 206% increase in student utilization.
