Chemistry Assessment Report 2004: Goal 1

Submitted Fall, 2004

Department Learning Goal #1 -- Upon completing a course required for a Chemistry degree, students will have developed the ability to critically evaluate and solve problems through the application of appropriate chemistry principles

Measurement Tools and Participants

The learning objectives associated with Department Learning Goal #1 were measured in two ways:

Standardized national exams (Direct Measure category 1. a. i.) produced by the American Chemical Society (ACS). Participants were all students in the following courses, each of which has an associated subject-specific ACS Exam.

Learning Objective Subject Area Course(s) Associated ACS Standardized Exam
General Chemistry
  • Fall CHEM 160 - 1st−Semester General Chemistry
    Spring CHEM 161 - 2nd−Semester General Chemistry
 
  • ACS 1st−Term General Chemistry Exam
  • ACS General Chemistry Exam (2−semester content)
 
Organic Chemistry
  • CHEM 361 - 2nd-Semester Organic Chemistry
 
  • ACS Organic Chemistry Exam (2-semester content)
 
Analytical Chemistry
  • CHEM 301 - Techniques of Chemical Analysis
  • CHEM 475 - Instrumental Analysis
 
  • ACS Analytical Chem. Exam
  • ACS Instrumental Analysis Exam
 
Physical Chemistry
  • CHEM 480 - 1st-Semester Physical Chemistry
  • CHEM 481 - 2nd-Semester Physical Chemistry
 
  • ACS Thermodynamics Exam
  • ACS Dynamics and Quantum Chemistry Exams
 

Direct measure 1. a. ii. - local final exams - were used for assessing academic achievement in CHEM 145 (Introductory Chemistry) and 150 (Introduction to Organic & Biochemistry). Participants were all students in these courses. Instructors divided their final exam questions into sections corresponding to material covered in the course. While individual exam questions may vary slightly from year-to-year, the types of exam sections and relative weighting will remain consistent.

Benchmark criterion for successful achievement:

  • Standardized national exams -- student exam scores will average at or above the 50th percentile (the national average)
  • CHEM 145, 150 Exams -- The average score on each exam section for each course will be no lower than 70%. If this benchmark is not met in three successive years, the format and delivery of the course will be reviewed and modified as appropriate.

All courses met the benchmark criterion. This included CHEM 160 and 480, courses that failed to meet the benchmark criterion last year. Future standardized exam results from all of the above courses will be monitored. Three successive years of failing to meet the benchmark criterion will trigger a more detailed review.

CHEM 145 Exam Section Exam Section Average Score (%) CHEM 150 Exam Section Exam Section Average Score (%)
Atomic Theory 71 Molecular Structure 73
Elements, Atoms, Ions 75 Functional Groups 73
Stoichiometry 72 Molecular Properties 73
Bonding 63* Chemical Reactions 73
Intermolecular Forces 68* Biochemistry 73
States of Matter 70    
*did not meet benchmark criterion

Scores from two content areas in CHEM 145 failed to meet the benchmark criterion. These results correlated with anecdotal laboratory evidence that students were weakest in the bonding and intermolecular forces material. Future exam results will be monitored. Two more successive years of failing to meet the benchmark criterion will trigger a more detailed review.
