Annual Progress Report (2011) Assessment of Student Learning DEPARTMENT/PROGRAM: Chemistry DATE SUBMITTED: June 2011 ASSESSMENT COORDINATOR: Darlene Gandolfi DEPARTMENT CHAIR: Darlene Gandolfi For each box, please address the following: LEARNING OBJECTIVE Which of your student learning objectives were measured? MEASURES USED What material from class did you use to evaluate the learning objective? (e.g., exams, written assignments, presentations, final project) What measure did you use? (e.g., exam scores, rubric, survey) Note: Please attach any rubrics or evaluative criteria RESULTS OF ASSESSMENT How many students were assessed? What % of students met the learning objective? ACTIONS RECOMMENDED TO IMPROVE STUDENT LEARNING What curricular or specific course concerns arose? What actions does your Dept. plan to take? What additional resources would be needed to implement these actions? LEARNING OBJECTIVE MEASURES USED RESULTS OF ASSESSMENT ACTIONS RECOMMENDED TO IMPROVE STUDENT LEARNING Students must comprehend the principles of all basic areas of chemistry (analytical, biochemistry, inorganic, organic, and physical). Standardized American Chemical Society (ACS) examination scores in core courses were compared to national norms and test results were evaluated by topic. The ACS examinations evaluate students’ knowledge of facts, skills, and procedures that should have been acquired as a function of the undergraduate curriculum. Organic Chemistry Eighteen undergraduate students took the FullYear Organic Chemistry ACS test (Form 2004). (Note: This year no post-baccalaureate students were enrolled in Organic Chemistry in Fall/Spring.) The class average for this exam was 37/70, which falls in the 45th percentile. (The national average (50th percentile) score was (39 + 12.16)/70.) By comparison to national norms, students performed within the standard deviation of the average. When considering the Organic Chemistry No actions planned for the course. However, a conversation with Admissions about recruiting stronger majors is warranted. This year, ACS examinations were administered at the completion of Organic Chemistry (Spring 2011), Analytical Chemistry (Fall 2010), Physical Chemistry I (Fall 2010 – Thermodynamics) and Physical Chemistry II (Spring 2011 – Quantum Mechanics and Statistics). Comprehensive exams were administered as the Senior Evaluation. These exams included the online version of the ETS Major Field Test in Chemistry and an inhouse comprehensive exam. undergraduate-only average from last year (34/70, or 37th percentile), this year’s results are an improvement. Four of the 18 students were Chemistry majors. The average for the majors was below average (21st percentile). This percentile was lower than that for four majors last year: 23rd percentile. It must be noted that some topics/questions that appeared on the test were not covered in the course. Additionally, this was a full-year test so students may not have recalled all topics covered in the Fall semester. Topics analysis is provided in Appendix A. Analytical Chemistry Four students (1 major, 3 minors) in CHM 3003 took the Analytical Chemistry ACS test (Form 2001). The class average for this exam was (22.3+ 3.27)/50, which falls in the 19th percentile. (The national average (50th percentile) score was (28.48 + 7.58)/50.) By comparison to national norms, students overall performed within the standard deviation of the average. All topics that appeared on the test were covered in the course. However, these topics were covered to varying degrees. It was found that students performed poorly on questions involving “Acid-Base Chemistry,” “Coordination Chemistry,” “Electrochemistry,” and “Spectroscopy” and that they performed well on questions involving “Data Evaluation and Error Analysis,” “Solutions and Volumetric Analysis,” and “Separations.” There were some differences in how students performed on the topics from last year. This could be a consequence of the background of the instructors: Inorganic (F08) versus Physical (F10). However, students continue to do poorly on the “Electrochemistry” questions. Comparison of results over the past three years indicates that students perform better on the ACS exam when CHM 3003 is taught by a full-time instructor: 52nd percentile (F08/Gandolfi) versus 19th percentile (F09/Wilkowski and F10/Ravi). A topics analysis is given in Appendix A. Analytical Chemistry (1) D. Gandolfi will teach CHM 3003 again in Spring 2012. However, a fulltime, tenure-track faculty member is needed in Analytical Chemistry. (2) A new, more student-friendly textbook has been selected for Spring 2012. The new text provides additional resources for student engagement. Physical Chemistry I – Thermodynamics (FALL) Eleven students (all Chemistry or Biochemistry majors; four from SUNY Purchase) in CHM 2009 completed the Thermodynamics section of the Physical Chemistry Combined Semester ACS exam (Form 2006). The class mean for this exam was (19.6 + 7.13)/40. Unfortunately, a national mean was not available since the ACS does not provide means for individual section. Upon further scrutiny, it was noted that Purchase students performed significantly better than Manhattanville students: 26.5/40 (Purchase) versus 15.7/40 (Manhattanville). Overall, students that performed better on regular course exams throughout the semester scored better on the ACS exam. (Notes: This was the first time that the Physical Chemistry ACS exam was administered as a final exam for Physical Chemistry I. This course was taught by an adjunct.) Physical Chemistry Students will complete an additional section with Thermodynamics section on ACS exam in CHM 2009 in Fall 2011 so that national norms are available for comparison. No actions are planned for CHM 2010. Physical Chemistry II – Quantum Mechanics & Statistical Mechanics (SPRING) Eight students (all Chemistry or Biochemistry majors; four from SUNY Purchase) in CHM 2010 completed the Quantum Mechanics and Statistical Mechanics sections of the Physical Chemistry Combined Semester ACS exam (Form 2006). The class mean for this exam was (23.75 + 6.68)/50. The national mean was (23.69 + 5.78)/50. Collectively, the students in Physical Chemistry II performed acceptably on the exam. Upon further scrutiny, it was noted that Purchase students performed significantly better than Manhattanville students: 28.5/50 (Purchase) versus 19/50 (Manhattanville). In general, students performed slightly better on the Quantum Mechanics questions (mean: 19.4/40) than the Statistical Mechanics questions (mean: 4.4/10). The ACS does not provide means for individual section. (Note: This was the first time that the Physical Chemistry ACS exam was administered as a final exam for Physical Chemistry II. This course was taught by an adjunct.) Senior Evaluation Two Chemistry majors took the online version of Senior Evaluation The design of the on-line version of the the ETS Major Field Test in Chemistry. One student scored in the 35th percentile and the other scored in the 25th percentile. While it was possible to view scores for each of the sub-sets of questions (i.e., Physical, Inorganic, Organic, and Analytical), faculty members were not able to see the specific questions that were asked of the students. (In order to have access to this information, the ETS requires at least five students to take the exam in a given cohort.) Given the poor performance of the two students on the ETS MFT, a faculty-developed comprehensive exam was administered. Like the MFT, all questions on this exam were multiple choice questions. Though the students fared somewhat better in certain sub-sets of questions (i.e., Physical, Inorganic, Organic, or Analytical), overall results were poor; one student answered only 21 out of 40 questions correctly and the other only 22 out of 40 questions correctly. Graduating Seniors to whom this same exam was administered in the past performed similarly on the test. ETS Major Field Test in Chemistry exam did not suit our needs, as we were not able to fully analyze questions on the exam. It is unlikely that we will use this on-line exam in the future. The paperbased version of the exam may be considered for the future. The in-house exam, though designed to contain questions that were definitely covered in the students’ courses, does not seem to be eliciting the desired scores. Additionally, it does not provide national standards with which to compare our students’ results. The use of the Chemistry GRE, will be discontinued indefinitely. Though it was used by the department for many years, the test proved to be too difficult and too expensive for our students. Other exams, like the American Chemical Society’s Diagnostic of Undergraduate Chemistry Knowledge (DUCK) exam, will be reconsidered on a trial basis. As a backup to the nationally normed exams, for next Spring, faculty members will design a new comprehensive exam, perhaps one with different types of questions. Additional Info While the department maintains that our majors must have basic comprehension of Biochemistry, we currently do not require a course in this target area. We cannot add this course unless we are permitted to hire a full-time professor who is able to teach a Chemistry-based Biochemistry course on an annual basis. This professor could be a joint appointment with the Biology department and offer the twosemester Biochemistry course required for the Biochemistry major, which has been taught by an adjunct instructor for several years. LEARNING OBJECTIVE MEASURES USED RESULTS OF ASSESSMENT ACTIONS RECOMMENDED TO IMPROVE STUDENT LEARNING Students must apply proper methodology and technique to the investigation of chemical principles through experimentation Scores on faculty-developed rubrics (see Appendix B) were utilized in CHM 3004: Chemical & Instrumental Analysis Lab. Two Senior Chemistry majors and one Senior Chemistry minor took CHM 3004 in Fall 2010. All three students demonstrated high levels of competency as evidenced by scores on rubrics designed to assess their efforts. (Cumulative data is in Appendix B.) The rubric used to assess methodology and technique was new this year. While the criteria make sense, the scoring approach needs revision. Assessment-focused lab practicals are still under consideration. However, rather than developing our own, we await the availability of the American Chemical Society’s practical exam series with scoring rubrics that will allow for national norming of student performance. LEARNING OBJECTIVE MEASURES USED RESULTS OF ASSESSMENT ACTIONS RECOMMENDED TO IMPROVE STUDENT LEARNING Students must independently operate chemical instrumentation and interpret instrument outputs. Scores on faculty-developed rubrics (see Appendix C) were applied to students’ use of instrumentation in select experiments in CHM 3004: Chemical & Instrumental Analysis Lab. Two Senior Chemistry majors and one Senior Chemistry minor took CHM 3004 in Fall 2010. Additional pre-lab practice problems may be utilized. All three students were able to operate the IR spectrometer and properly interpret their results in one experiment. All three students were able to operate the UV-Vis spectrophotometer in two experiments. However, they all had difficulties with data interpretation and calculations involving their UV-Vis data in both experiments. (See Appendix C.) Students have the opportunity to practice calculations with UV-Vis data in the lecture portion of the course (CHM 3003). Calculations are also reviewed in the pre-lab discussion. Extra time was spent explaining the necessary calculations for the second UV-Vis experiment, but no improvement was achieved. It is notable that one of the sections on which students performed poorly on the ACS Analytical Chemistry exam was on Spectroscopy (see above). NOTE: The content of CHM 3004 was redesigned during the summer of 2010 to incorporate more instruments for the purpose of providing more opportunities for this learning objective to be measured. Therefore, this year’s assessment was supposed to include additional instruments, namely the Nuclear Magnetic Resonance spectrometer, the Gas Chromatograph, and the Liquid Chromatograph. However, this assessment was hindered by technical difficulties with these instruments. It is imperative for effective student learning that properly functioning instrumentation is available. To that end, a full-time or part-time lab technician is needed. Maintenance is also needed annually. Specific instruments used in this year’s assessment were the IR spectrometer and UV-Visible Spectrophotometer. One of the three students, who consistently sought additional help with data interpretation in a different lab course (CHM 2016) last year was more independent this year. LEARNING OBJECTIVE MEASURES USED RESULTS OF ASSESSMENT ACTIONS RECOMMENDED TO IMPROVE STUDENT LEARNING Students must gain sustained, hands-on experience in the scientific research process that unifies their mastery of chemical principles and techniques with problem-solving abilities and oral and written communication proficiencies. Scores on faculty-developed rubrics (see Appendix D) were utilized in CHM 4450: Research. Two Senior Chemistry majors took CHM 4450 in Fall 2010. The written component of upper-level lab courses will be scrutinized to determine if more emphasis on the identification of experiment objectives is needed. Overall, the students’ performance was satisfactory as evidenced by scores on rubrics designed to assess their efforts. However, as with past students, these students had difficulty identifying the main objective of their project and describing the purpose and progression of their experimentation in their final papers. These problems persisted, despite the fact that the students were required to submit drafts of sections of their paper throughout the semester, these drafts were reviewed by their instructor and returned promptly, and the instructor discussed her comments with the students upon returning the drafts. (Note: Drafts were adopted rather than the monthly research reports mentioned in the Fall 2008 assessment report.) The students were also not able to use technical vocabulary correctly in their papers. One area in which both students performed very well was in the application of safe practices in the laboratory. However, neither student demonstrated the levels of proficiency and confidence in performing their experiments that are expected of a graduating Senior. 1. More faculty-led discussion about relevant journal articles is also needed. Reading and discussing more articles would help students become accustomed to appropriate language and format for scientific writing. However, the extra time needed for this undertaking warrants addition of either a Seminar course or another semester of research. To that end, more full-time faculty members are needed. The eventual adoption of laboratory practicals that is mentioned above should help the department identify skill-area needs earlier in the students’ academic career. Addressing problem areas earlier will enable the students to be more prepared for Senior-level research. NOTE: To improve the students’ research learning experience, it is necessary to invest in properly functioning instrumentation and library resources. Are you satisfied overall that your majors are achieving your defined learning objectives? Chemistry majors are only minimally achieving the department’s learning objectives. This is most apparent when comparing the scores of the majors to the national standard on the American Chemical Society (ACS) exams. Notably, Chemistry majors from SUNY Purchase, who took courses at Manhattanville, scored better on the ACS exams than Manhattanville Chemistry majors. It is unclear why this distinction exists. In the laboratory, students perform satisfactorily overall. However, a higher level of competency is desired. 2. What program strengths became evident as a result of this assessment? The department has successfully emphasized the importance of safety in the chemical laboratory. Students also demonstrated high levels of competency in the application of proper experimental methods and techniques. 3. What program weaknesses became evident as a result of this assessment? In the laboratory, students had difficulties making connections between what they learned in lecture and applied in the laboratory. Research students also had trouble identifying the objectives and goals of their full-semester research projects. More emphasis will be placed on developing these skills in students. 4. Are there any institutional-level actions (i.e., those that extend beyond the purview of your department into other areas of the College) that you would recommend? Because of the significant difference in ACS exam scores of Manhattanville versus Purchase students, the department perceives a need to work with Admissions to recruit academically stronger majors. In their writing courses, students should learn about the appropriate use of synonyms.
