Success GTAs: What Are They and Why Do We Need Them

Posted on by | Leave a reply

Instructors Margie Haak and Paula Weiss will give a seminar titled, “Success GTAs: What Are They and Why Do We Need Them” at the 2014 Biennial Conference on Chemical Education, August 3-7 2014 at Grand Valley University in Michigan.

In Fall term 2013 we created the Success GTA position as part of a larger university-wide pilot program focused on increasing student success in first-year courses that historically have high percentages of students earning grades of D or F, or withdrawing from the course (DFW rates).  The fall term enrollment in our three different general chemistry courses (science majors, engineering majors, and majors other than physical sciences) range from 750 to 1200 students and each course has between 3 and 7 lecture sections.

The Success GTAs had several roles in the courses.  They all taught at least one recitation or lab section in their assigned course, half the load of a regular GTA .  In addition they were responsible for identifying and contacting students who were doing poorly in some aspect of the course: not registered for Mastering Chemistry or not completing the Mastering Chemistry assignments, exams scores well below the class median, not attending recitations or labs.  They were also part of the CH 199 courses that were offered to provide extra support to students struggling in general chemistry.

We will present results showing the impact of the Success GTA interventions, discuss the training Success GTAs received prior to the start of fall term classes, and lessons learned from the first year of this program.

Design and Implementation of General Chemistry Support Course

Instructors Paula Weiss and Margie Haak will give a seminar titled, “Design and Implementation of General Chemistry Support Course” at the 2014 Biennial Conference on Chemical Education, August 3-7, 2014 at Grand Valley State University in Michigan.

~~~~~~~~~~

We will discuss the design and implementation of a full-year support course to  increase student success in General Chemistry. The course provides support for developing problem-solving skills, effective study skills for chemistry courses, math review, and additional exposure to the chemistry concepts covered in General Chemistry.  In the classroom students are engaged in problem-solving with other students, with guidance from general chemistry faculty and graduate teaching assistants. This presentation will focus on lessons learned in our first year of offering the course and plans for future implementations.

Less Class Time, More Learning

Instructors Margie Haak and Michael Burand will give a lecture on Less Class Time, More Learning at the 2014 Biennial Conference on Chemical Education, August 3-7 at Grand Valley State University in Michigan.

A hybrid-format general chemistry course for science-majors was implemented in the winter term of 2014. Two sections of approximately 160 students each were included. This course was a “trailer” course insomuch as students began the sequence in the second 10-week term of the academic year. Students in trailer courses have historically been more at risk for poor academic performance.

The format of the course included short, topical videos which were custom-made for this course and were made available to students online. Students were assigned to groups of approximately four for the duration of the term and biweekly class meetings consisted almost exclusively of students working on solving problems within their groups. Generally two faculty members and four teaching assistants were present to assist student groups. Typically some time was reserved at the end of the class periods for student groups (selected at random) to come before the class and present their solution to a problem.

Preliminary data show that students in this hybrid course performed significantly better on exams than historical averages for the traditional lecture format. This result is especially noteworthy given that the students in the hybrid course have only 60% of the class time compared to students in the traditional version of the course. A survey of students’ views regarding this hybrid course format was also conducted and will be discussed.

Letter Writing: A Pathway to Better Laboratory Comprehension

Instructor Michael Burand will give a presentation titled, “Letter Writing: A Pathway to Better Laboratory Comprehension” at the 2014 Biennial Conference on Chemical Education, August 3-7 at Grand Valley State University.

General chemistry students in honors and majors-only laboratory courses are required to write a letter in lieu of a traditional laboratory report for one of their laboratory projects. The students use the letter to explain their results to a recipient whom they are told does not necessarily have background in science. This requirement to explain their laboratory results in nonscientific terms causes the students to think more thoroughly about the underlying concepts involved. Indeed, survey results indicate that 94% of the laboratory students polled felt they had gained a deeper understanding when they wrote the letter as opposed to a traditional laboratory report. The details of the assignment will be discussed along with students’ survey responses.

The laboratory activity chosen for this letter-writing project involved testing for lead contamination in urban soils via atomic absorption spectroscopy. This provided a viable means of incorporating a service-learning aspect into the project. Students indicated that they put forth a more substantial effort in writing the letter knowing it would be sent to an actual recipient, not only the student’s TA and/or laboratory instructor. Thus, this project combines the nontraditional laboratory pedagogical approach of letter writing with a service-learning component. How this leads to students attaining a deeper understanding and facilitates better student engagement and ownership will be discussed.
