  1. First semester General Chemistry (CHEM 200) at SIUC • Required in every Dept. in the College of Science and majors in Engineering and Agriculture • Typically enrolls ca. 600 students per AY • Prior to AY07 taught using a typical large university format→ Large lecture sections, typically 80-200 students→ Attendance expected, but not monitored→ 4 mid-semester, multiple choice exams, plus comprehensive final→ Homework assigned, but not graded→ Blackboard used for lecture note and grade posting Southern Illinois University Carbondale(Go Saluki’s!) Historically, the pass rate (C, or better) for CHEM 200 has been poor (40-50%) and is trending downward!

  2. Beginning in AY07 the Department decided to implement 2 major technology-based changes in the delivery of the CHEM 200 course. • All students are REQUIRED to purchase the eInstruction Classroom Performance System (CPS) and this system is used in every lecture section.CPS: 10% of grade; typically 1-3 questions / lecture; 1 point for trying / 2 points if correct; peer learning encouraged. • All students are REQUIRED to attend weekly, 1-hour, GTA proctored Structured Learning Workshops (SLWs) wherein the McGraw Hill ARIS system is used to deliver algorithmic computer-based problem sets.SLW ARIS: 10% of grade; typically 8-12 questions / 1-hr SLW; peer learning encouraged.

  3. Analysis of student outcomes shows that the use of this technology resulted in a substantial improvement in student success. Grade AY06-07 % AY07-08 % A 81 12.7% 89 15.5% B 108 16.9% 113 19.7% C 143 22.4% 143 25.0% D 107 16.7% 85 14.8% F 119 18.6% 94 16.4% W 81 12.7% 49 8.6% Total 639 573 %Pass 52.0% 60.2%

  4. What is the source of the success? • Use of the “clicker” allows us to encourage attendance and engage students in the lecture. • Required attendance at SLW-ARIS sessions forces students to develop at least minimal study discipline. • In-class and SLW-ARIS exposure to relevant problems challenges student perception of “understanding” the material. • Small class size SLW-ARIS sessions encourage GA and peer mentoring when comprehension challenges are identified.

  5. Classroom Performance System (CPS) Sample Size: 168 Responses Do the questions asked in lecture requiring an in-class response using your CPS handheld device (aka clicker) help you understand the concepts?a. Neverb. Rarelyc. Sometimes Fall 2007: 3.53d. Oftene. Always Has the knowledge that you will be asked questions requiring use of the CPS handheld device improved your attendance in lecture?a. Definitely nob. Not surec. Perhapsd. Often Fall 2007: 3.90 e. Definitely yes Did the in class response questions help your final grade in the course?a. Definitely nob. Not surec. Perhaps Fall 2007: 3.07d. Yese. Definitely yes

  6. Structured Learning Workshop Sample Size: 168 Responses 181 Responses Did the questions asked in the Structured Learning Workshops help you understand the concepts?a. Neverb. Rarelyc. Sometimesd. Often Fall 2007:3.95 Spring 2008: 4.13e. Always Did you find having a teaching assistant present useful when you needed assistance with the questions?a. Neverb. Rarelyc. Sometimesd. Often Fall 2007:4.44 Spring 2008: 4.50e. Always Did the Structured Learning Workshops help your final grade in the course?a. Definitely nob. Not surec. Perhapsd. Yes Fall 2007:3.81 Spring 2008: 4.05e. Definitely yes

  7. Some cost / benefit comments … • What did it cost to do this? • Students paid for the clicker, the registration code and the ARIS registration • Implementation required 4 GTAs @ $15,000 / 9-month salary = $60,000 • Computer lab renovations (one time charge) = $25,000 • What is the return? • An 8% increase in student success = 50 more students passing CHEM 200 / AY • If all students (i.e. 100% rather than 40%) register for 1 additional AY: 30x $10,000 / AY = $300,000 • If a proportionate no. (i.e. 70% rather than 40%) complete their degree in 5 years: 15x $10,000 / AY x 3 years = $450,000 • If the SLW is turned into a 1 credit hour course 600x $250 = $150,000 So, for a ~$90,000 investment there is potentially a $900,000 return!
