Assessment Measures Assessment Results Use of Results In the boxes below, summarize the methods used to assess program or discipline, or course outcomes during the last year. Students complete the Light & Spectroscopy Concept Inventory as a pre-course and postcourse survey. The Normalized Hake Gain is used as a measure of student learning gains. Students complete a precourse/post-course concept inventory regarding scientific thinking. The Normalized Hake Gain is used as a measure of student learning gains. In the boxes below, summarize the results of your assessment activities during the last year. In the boxes below, summarize how you are or how you plan to use the results to improve student learning. Fall 2009 D01 (Case) <g> = .07 N01 (Case) <g> = .06 E50 (Loranz) <g> = .26 Assessment data will be shared with part-time instructor Case. Light & Spectroscopy Concept Inventory is a nationally validated intro astronomy content diagnostic. I will continue to use this survey. Scientific Thinking must be explicitly addressed. I have been revising my section of AST 104 to do this. So far results are encouraging that mitigating student miscomprehensions about scientific thinking can be done. I am developing a Nature of Science concept inventory. I will use the results from this year to refine the questions asked in this survey. Spring D01 (Loranz) <g> = .38 N01 (Case) <g> = .07 Students appear to enroll in our non-majors science courses with almost no understanding of scientific thinking. In addition, unless specifically addressed as part of the course curriculum, students do not show any improvement in their understanding. Effect on the Program, Discipline or Course Based on the results of this assessment, will you revise your outcomes? If so, please summarize how and why in the boxes below. Outcome #3: PHYS 151 Content Mastery: Actively engaged students will gain a working knowledge of algebra based Newtonian Mechanics. Administer Force Concept Inventory (FCI) as pre/post test. Measure learning gains by calculating the Hake gain. Fall 2009 D01 (Jensen) – no data N01 (Porter) <g> = .43 Outcome #4 PHYS 180 & PHYS 181 Content Mastery: Actively engaged students will gain a working knowledge of calculus based Newtonian Mechanics and Maxwellian Electromagnetic Theory Students solve exam problems closely tied to course learning objectives. Please see attached summary. Jensen and Porter have the FCI data for their sections. I am not aware of how they will use this data. Our use of the FCI is giving us results consistent with those of other colleges and universities across the nation. I will continue to use the FCI as a benchmark for student learning gains in PHYS 151. Please see attached summary. This assessment approach provides a good summary of student performance. However, it would also be useful to measure learning gains. I am still looking for a reasonable pre-test/post-test diagnostic for use in PHYS 180 and PHYS 181. Spring 2010 D01 (Jensen) <g> = .28 N01 (Porter) <g> = .38 For Discipline Assessment Reports: I have reviewed this report: ________________________________________________ Dean _______________________________________________ Vice President for Academic Affairs & Student Services Date_______________ Date_______________ Physics and Astronomy Assessment for 2008-2009 Results for AST 104 FACULTY INVOLVED Daniel Loranz (tenured faculty) and Clint Case (part-time instructor) SUMMARY OF ASSESSMENT ACTIVITIES I used the Light and Spectroscopy Concept Inventory (LSCI) to assess student learning gains in introductory astronomy. The LSCI is a nationally validated diagnostic used in many intro astronomy courses across the nation. The LSCI was administered as a pre-test and post-test and these results were used to calculate the normalized Hake gain. WHAT WERE THE RESULTS? Fall 2009 – AST 104 D01 Instructor: Clint Case Average Hake Gain for the class = 0.07 Fall 2009 – AST 104 N01 Instructor: Clint Case Average Hake Gain for the class = 0.06 Fall 2009 – AST 104 E50 Instructor: Daniel Loranz Average Hake Gain for the class = 0.26 Spring 2010 – AST 104 D01 Instructor: Daniel Loranz Average Hake Gain for the class = 0.38 Spring 2010 – AST 104 N01 Instructor: Clint Case Average Hake Gain for the class = 0.07 SPECIFICALLY, HOW ARE YOU OR HOW DO YOU PLAN TO USE THE RESULTS TO IMPROVE STUDENT LEARNING? Examining individual questions, students in my sections appear to need more help understanding the following concepts. (Data available upon request.) - Understanding the different sources for emission spectra, absorption spectra and continuous spectra. - Understanding that color and spectral lines are not linked. - Being able to apply Doppler shift concepts. - Being able to rank star sizes based upon their luminosity plots. Clint Case will also have his LSCI data. I am not aware of how he will use this information. BASED ON THE RESULTS OF THIS YEAR, WILL YOU REVISE YOUR ASSESSMENT PLAN? HOW AND WHY? The LSCI is a nationally validated diagnostic for intro astronomy, and it has provided useful data this year. I will continue to use the LSCI as a benchmark. Results for AST 104, CHEM 100 and PHYS 100 FACULTY INVOLVED Tenured Faculty: Daniel Loranz Part-time Faculty: Rio Andaya, Clint Case, John Hadder, Cullen Jones, Steve Kohl, Cindy Porter, Ileana Tibuleac, Robert Weise SUMMARY OF ASSESSMENT ACTIVITIES During the 2008/2009 academic year, I collected student responses to the question “What is Science”. Using these responses, I have written a draft survey on scientific thinking. For 2009/2010, this draft survey was used to assess student learning gains on understanding scientific thinking. The survey was given as a pretest/post-test to all face-to-face sections of AST 104, CHEM 100, and PHYS 100. In addition, all instructors of face-to-face AST 104, CHEM 100 and PHYS 100 sections were asked to complete a short self-evaluation regarding whether or not they directly address scientific thinking in their courses. Only three instructors responded to this request. Based upon these responses and other anecdotal stories, most instructors of these courses are apparently NOT directly addressing scientific thinking in their classes. Instead they are focusing on discipline specific content and hoping that students will learn about scientific thinking as a side benefit of engaging with the specific scientific models presented in the course. My hypothesis is that this approach is not working, and I have begun a significant revision to my section of AST 104 to directly address scientific thinking as a fully integrated part of the course. I began these revisions in my Fall 2009 AST 104 E50 section. These revisions were further refined in my Spring 2010 AST 104 D01 section, and will be refined yet again next year. WHAT WERE THE RESULTS? Spring 2010 AST 104 N01 CHEM 100 D01, D02, D03, N01 PHYS 100 D01, D02, N01 Spring 2010 AST 104 D01 Aggregate Scores Ave. Pre-Score = 69% Ave. Post-Score = 71.5% Ave Hake Gain = .07 Ave. Pre-Score = 69% Ave. Post-Score = 80.6% Ave. Hake Gain = .37 The data suggests that students start with a poor understanding of the scientific thinking, and that experiences in AST 104, CHEM 100, and PHYS 100 predominantly have no impact on improving student understanding of this topic. This lack of affect is not surprising, given that currently the AST 104, CHEM 100 and PHYS 100 sections predominantly do NOT explicitly address the scientific thinking. The exception is for my revised section of AST 104, where I do explicitly address scientific thinking. In that case, students start on par with other sections but experience an average learning again of .37 and have an average final score of 80.6% on the post-course survey. SPECIFICALLY, HOW ARE YOU OR HOW DO YOU PLAN TO USE THE RESULTS TO IMPROVE STUDENT LEARNING? As we should perhaps have expected, indirectly addressing scientific thinking (e.g. by example) appears to have almost no effect on improving student of this topic. And yet, scientific thinking is a learning objective for all these non-majors science courses. Encouragingly, directly addressing scientific thinking does appear to significantly improve student understanding of this topic. As a result, I will continue to refine my curriculum to specifically address this topic. As this curriculum begins to take shape, I will then happily share it with other instructors in these non-majors science courses. BASED ON THE RESULTS OF THIS YEAR, WILL YOU REVISE YOUR ASSESSMENT PLAN? HOW AND WHY? The pre/post survey described here is still undergoing refinement. I will use student responses from this year to further improve the survey. Results for PHYS 151 FACULTY INVOLVED Lars Jensen (tenured faculty) and Cindy Porter (part-time instructor) SUMMARY OF ASSESSMENT ACTIVITIES We continue to use the Force Concept Inventory (FCI) to assess PHYS 151 student learning gains in the Analytical Thinking learning outcome in the context of Newtonian Mechanics. The FCI was administered as a pre-test and post-test and these results were used to calculate the normalized Hake gain. WHAT WERE THE RESULTS? Fall 2009 – PHYS 151 D01 Fall 2009 – PHYS 151 N01 Instructor: Lars Jensen Instructor: Cindy Porter No Data. Jensen decided to not participate in Average Hake Gain for the class = 0.43 this assessment activity – perhaps because only 3 students were left in his section by the end of the semester. Spring 2010 – PHYS 151 D01 Instructor: Lars Jensen Average Hake Gain for the class = 0.28 Spring 2010 – PHYS 151 N01 Instructor: Cindy Porter Average Hake Gain for the class = 0.38 For comparison, nationally reported Hake gains from the FCI are … - about 0.23 +/- 0.04 in traditional lecture style physics courses - about 0.48 +/-0.14 in active-learning style physics courses. SPECIFICALLY, HOW ARE YOU OR HOW DO YOU PLAN TO USE THE RESULTS TO IMPROVE STUDENT LEARNING? Jensen and Porter both have their FCI data. I am not aware of how they will use this information. BASED ON THE RESULTS OF THIS YEAR, WILL YOU REVISE YOUR ASSESSMENT PLAN? HOW AND WHY? The FCI has now been used successfully for many semesters to measure student learning gains in analytical thinking within a Newtonian Mechanics context. We will continue to use this nationally validated diagnostic tool. Results for PHYS 180 and PHYS 181 FACULTY INVOLVED Daniel Loranz SUMMARY OF ASSESSMENT ACTIVITIES - Students answer fifteen exam questions during each semester. These exam questions are carefully written to address the specific learning objectives for the course. - Each question is scored on a scale from 0 to 15 points. - Scores of 10 thru 15 points indicate student success on the learning objective. (After the questions are scored, students are allowed to submit corrections. An initial score of 10 points means students can still possibly at least a “B” grade on the question after submitting corrections.) WHAT WERE THE RESULTS?

In general, PHYS 180 and PHYS 181 students appear to be successfully learning the course content, with some noticeable exceptions. These are addressed below. PHYS 180 - Ex2 Q4, Ex2 Q5, and Ex3 Q1: Rotational Kinematics and Rotational Dynamics. Students have difficulty transitioning from linear mechanics to rotational mechanics, especially in grappling with rotation axes, center of mass, and moment of inertia. Possible remedies might include an additional lab experience on this set of topics and/or the possibility of deleting the vector nature of rotation from the curriculum. - Ex3 Q4: Combined Analysis of Translational and Rotational Motion. This is an end-of-semester, big-picture application problem. Even though students may have mastered all parts needed to solve this comprehensive problem, they still struggle with assembling all the pieces for a complete solution. Given the introductory nature of this course, I am not surprised that students have difficulty with this sort of comprehensive problem. - Ex3 Q5: Simple Harmonic Oscillators Data on this problem is an outlier. Review of scores show that students generally did just fine with the physics of this problem but panicked when the problem presented the binomial expansion and asked students to use the expansion to simplify their solutions. Bottom line – students did fine with the physics part of this problem, and only balked unnecessarily at the math. PHYS 181 - Exam 2 Q2: Conceptual Understanding of Simple DC Circuits Students are not making the connection that knowledge of power usage in an Ohmic circuit gives rankings for both current and potential. This link should be made more explicit in the lab for this topic. BASED ON THE RESULTS OF THIS YEAR, WILL YOU REVISE YOUR ASSESSMENT PLAN? HOW AND WHY? I will continue to use this approach. The assessment method described for PHYS 180 and PHYS 181 provides a reasonable summary of student performance on all major course learning objectives. Unfortunately, the current assessment methodology does not measure learning gains (only final student performance). So I will also examine the utility of multiple-choice style pre-test/post-test diagnostic tools for use in PHYS 180 and PHYS 181. It would be valuable to know what student learning gains are.
