Critical Thinking

In my differential equations class, students ran an experiment on the accuracy of a nondigital thermometer.  Most directions for use of nondigital thermometers say to leave under the tongue for 2 minutes, so students tested the accuracy of this.   Three groups performed different activities for two minutes (cheweing gum (placebo group), jumping jacks, and drinking a cold refreshing beverage).  Students collected temperature readings every 30 seconds for 4 minutes.  Data was run through Logger Pro, and students analyzed data using best fit lines.

Gene expression is a complex multi-step process that students struggle to learn. There are many terms to memorize and then students need to remember the functions and roles of all the molecular players and the order in which each molecule participates in the overall process. I currently use lecture, diagrams, animations, a worksheet and websites to teach this topic and I have also incorporated a hands-on lab using manipulatives where the students create their own working model of gene expression using yarn, foam pieces, pasta, playdoh, post-its and other random junk (see attached pics).

In my EDU222 class, we are analyzing Special Education models.   Last term I presented on three models, set up in-class discussions, and had students write a research-based essay analyzing the 3.  This semester, I modified the cycle to include a  variety of formative assessments and ended with an in-class debate and essay. Students were much more analytical in their approach and were much better able to form their own conclusions as to what Special Education Model is most effective and why.

This clicker case study will be designed to use existing knowledge gained from class helping make connections between what they might consider separate concepts (chemistry, mitosis, genetics and cancer). This case study will allow student to plan and diagnose, treatment plan, analyze the results of the treatment plan and evaluate if this treatment plan would be ideal for this particular patient.

What I will assess: I will be assessing the comprehension of material to answer multiple choice questions assessing their knowledge of

Students struggle with using direction fields to solve a given problem.  In the 1st two semesters, lecture was primarily used with handouts and group work being utlized more in the last 3 semesters.  Students have continually received a C grade on the direction field exam question and a C/B average on homework questions.  In Fall 2014, the handout was modified, and students worked in groups with no guidance from the instructor.  Technology as incorporated as well (MATLAB) to graph the direction fields.

Minicases provided to students contain info about the bacterium from the patient and the patient signs/symptoms. The objective for the students is to correctly ID which organism causes the infection and explain why to support their answer. Minicases provide info concerning both of the areas(bacteria & patient) in 2-4 sentences. I wanted to see if students could id these two areas cold turkey - no lecture from me, just reading the minicase. The majority of students just identified bacteria info as important - 70%. Only 25% identified both disease info and bacterial info.

As a semester research project for BIO 160, I have students research a disease and write a paper and present with a group their research. In past semesters I have simply posted the grading rubric on the LMS. This semester I decided to present the rubric and have students practice using the rubric in efforst to increase student awareness of thier contribution to their grade. I find that students are not fully aware of thier contribution to thier grade. I am hoping that taking the time to teach students how the project will be evaluated will result in higher quality projects.

In fall 2013, Dwain Desbien and I taught MAT221/PHY121 learning community (LC).  In spring 2014, 8 of these students went on to take MAT230 with me (calculus II).  Here is some info on the LC students as compared to the non LC students.  

A question on my BIO156/181 Unit 5 exam addresses Mendelian genetics and the inheritance of a trait from parents. The trait in question is inherited in a simple Mendelian manner (one gene with two alleles, one allele being dominant and the other allele being recessive.)   Originally the question was about hitchhiker's thumb and involved a kind of "double negative" statement, where "lack of the thumb" was dominant.  I think this wording was making it hard for students to think through the problem.

Science faculty are constantly hearing from their students, "This isn't math! I didn't learn this in my math class". Many students are not able to transfer what they learned in math into their science courses.  Most of the concepts in MAT091 are crucial to success in science.  Throughout the semester, I met with 6 science faculty to discuss HOW students see these topics in science classes.

The general public has numerous misconceptions about science. My PHY101 students explored this intersection of science with society by researching a topic, performing a survey, and creating an educational website. The students chose a topic from a list to research. After researching the student came up with a question to test the misconception and three follow up questions to challenge it. The students presented their results in a non-traditional format, an informative website. This educational website was evaluated based on the attached assessment sheet.

In the last 5 years the chemistry program has made a switch to a fully active learning pedagogy. While we are finding this to be a huge success for the students, it is causing some problems for our instructors. Since this is a novel approach for teaching chemistry classes, most content qualified instructors are not familiar with how to present curriculum in this way.

In teaching Muscle function, I have always used an activity where I physically demonstrate the actions to students. Students then stand and work in pairs, mimic the movements on their own body, and evaluate their partner's motions. I circulate and correct with each new motion. When doing the activity as a class, and only their partner is working with them, students think this activity is fun and interesting. The class is excited and loud.

A new supplement for the microbiology text called Mastering Microbiology was recently released by the publisher. I had heard positive things about the Mastering Biology for BIO 181 (pre-req for micro) and decided to implement Mastering Micro in a like manner. For two semesters prior to utilizing Mastering, the average grade overall at the end of the semesters  was 74.64% (n=73).Not a bad average but many students indicated they wanted practice and micro is very conceptual. I was not sure exactly what I wanted to see with my students other than overall increase in performance.

Many people do learning communities (see MAT and CPD LC's) to try improve retention in classes.  However, the LC between PHY 121 and MAT 221 has been about trying to improve student understanding of the concepts of physics and calculus and how they fit together.  Retention and success in these coures have been fine which is reason for focus on understanding rather than retention.  From the attached file it can be seen that on the Force Concept Inventory the LC students did better than traditional class even though they had less math preparation for the course.
