Introduction

Learning outcomes for the geology major were assessed according to 8 criteria that that correlate with the 8 learning outcomes developed by the Geology Department faculty (Appendix 1).  In order to gage the department’s effectiveness in guiding students towards achieving its learning outcomes, we decided that the faculty would assess student performance in the required courses for the major.  We developed a checklist for faculty to rank the student’s achievement of each of the learning outcomes on a 5 point scale (Appendix 2). 

            During the 2004-2005 academic year, all 9 of the required courses for the geology major were taught.  Due to the departure of a faculty member at the end of the spring semester, one of the courses was not assessed.  Two of the courses (GEOL 1121 and 1122) are part of the undergraduate core.  Most of the students in these courses are not geology majors.  Many large sections of these courses are taught each year.  In contrast the other courses in the geology major are populated exclusively by majors.  The class sizes are small (10-15 students) and only one class is offered each year.  Most of our majors take 3 or 4 of these courses in a single year.  Therefore, for example, many of the same students that were assessed in GEOL 3002 were also assessed in GEOL 4013 and GEOL 4009.  Due to the difference in populations between the core courses and the courses for majors, we decided to consider them separately here. 

 

Results from Assessment of Student Learning Outcomes

 

GEOL 1121 and 1122

            These courses are part of the undergraduate core as well as required courses for our major.  With the exception of a single section for freshmen honors students, they are taught in large (>40 students) sections and assessed with multiple choice exams.  Labs are taught by teaching assistants.  Performance in lab is also assessed by multiple choice tests.  Responses for the assessment checklist for faculty teaching 1121 and 1122 are compiled in Table 1.  Nine sections were evaluated.  The columns list the number of courses assessing each outcome, the average assessment score and the standard deviation.

Faculty members disagree as to whether they were able to assess student’s performance on outcomes 1-4 and ratings of student performance by faculty are highly variable.  Since these are large classes, taught in very much the same style, such large variations between achievement of learning outcomes of entire sections is not expected.  We attribute the apparent variation instead to differences in faculty expectations and interpretation of the meaning and goals of the checklist instrument.  This interpretation is supported by the observation that average standard deviations of scores assigned by individual faculty members for learning outcomes 5-8 (which are content oriented) is much smaller (s=.12) that the average of the standard deviations for each outcome (s =1.2) as assessed by all faculty members. 

 

Upper Division Required Courses

Responses for the assessment checklist for faculty teaching required courses in the geology major are compiled in Table 2.  Six courses, GEOL3002, GEOL4013, GEOL4009, GEOL4015, GEOL4016, and GEOL4095 were assessed. The columns list the number of courses assessing each learning outcome, the average assessment score and the standard deviation.

Courses in the major are highly focused.  No course is expected to address all of the learning outcomes (Appendix 1).  As observed with the checklist for 1121 and 1122, faculty rankings of student performance are highly variable.  This could represent 1) differences in subpopulations of majors, 2) improvement as majors move through the program or 3) differences in faculty expectations and interpretation of the meaning and goals of the checklist instrument. The second interpretation is not supported by the observation that the lowest scores for objective #1 were awarded by the instructor of GEOL4016 and 4015, which are generally the last academic year courses taken in the major.  The first interpretation is not supported by the observation that the same instructor rated essentially the same cohort of students as excellent for objective #1 during the spring semester and good during the following summer semester.  The data can best be explained by assuming that some faculty have differing expectations for students and that some faculty interpreted the instrument as asking them to rate how well their courses addressed each learning outcome rather than how well students performed relative to those outcomes. 

 

Suggestions for Improving Student Performance

 

GEOL 1121 and 1122

            Faculty suggestions for improving student performance include the use of open discussions in class, encouraging students to work in groups during lab, adding more specimens to lab exercises, spending more time in lecture on certain topics and adding more problem solving and critical thinking type questions to exams. 

 

Upper Division Required Courses

            Suggestions for improving student performance included adding writing assignments to courses, adding computer programming, GIS and other technology based exercises to courses, as well as adding more in-depth thin section interpretation, increasing the diversity of rock types in labs and adding questions to labs that stimulate critical thinking. 

 

Suggestions for Improving Department’s Assessment Strategy

 

GEOL 1121 and 1122

            The department will improve the assessment of learning outcomes in these courses by incorporating a set of questions into the student’s final exams that are specifically designed to assess the department’s content objectives (objectives 5-8) and to test the student’s performance in critical thinking and quantitative problems.  The most likely venue for these questions will be the laboratory final, since there is already a single exam used for all sections. 

 

Upper Division Required Courses

            To better assess student outcomes the department will modify the learning outcomes assessment checklist to contain a more detailed rubric.  The rubric will separate different components of the learning outcomes, eliminate faculty confusion and narrow the latitude for personal interpretation of terms (such as good and very good).  For example:

Conclusion

            Our first efforts as assessing our student’s achievement of our learning outcomes has allowed us to learn more about the assessment process and has benefited the program by helping faculty to focus their courses to more specifically address the learning outcomes.  For example, as a result of this process, two of the major’s courses (GEOL3002 and GEOL4015), that did not have a writing component, have now been converted to writing intensive courses.  In the coming year we will refine our assessment strategy to improve data quality.
