1 Assessing Student Learning Outcomes in Chemistry Dr. Saloua SaidaneSan Diego Mesa College
2 How did it Strat? Accreditation As part of accreditation process, Intitution required that:Each department develops Program Level SLOsDevelop, and assess, Course Level and Program level SLOsInstitution purchased software to help achieve requirements.
3 Taskstream It is a software that allows to: Map/align Institution SLOs to Department SLOs as well as department SLOs to course level SLOs.Map assessment activities to Course Level SLOs.Publish SLOs, assessment plans and results at the institution, department and course levels.
4 What did we do?Since Assessment had to be done both at the course and program level, we adopted the following:Develop Chemistry Department SLOs.Use course outlines and find common activities/topics in these courses.Cluster Courses based on Activities/topics.Align Activities to department’s SLOs.Align department’s SLOs to institution’s SLOs.Develop assessment plan for the accreditation cycle.
5 Mesa College Chem Dept SLOs 1. Communication: Demonstrates ability to report scientific information appropriately.2. Critical Thinking: Utilizes the scientific method to analyze and interpret data.3. Technology awareness: Investigates questions utilizing modern and appropriate tools.4. Personal responsibility: Comes prepared for class and does assigned work thoughtfully.5. Environmental responsibility: Demonstrates understanding of impact of chemistry on environment and society.
6 Clustering Courses Lab Courses based on activities (Lab notebook). Lecture Courses based on topics in course outlines.
7 Lab Courses Assessment Department developed lab notebook policy and Lab notebook rubric to assess the SLOs as part of the lab courses.
8 Chemsitry Department Lab Notebook Policy All students will maintain a lab notebook. There will be a progression of rigor and formality as follows:Fundamental and Intro Chem Gen. Chem I Gen. Chem II/Org ChemTitle Title TitlePurpose Purpose PurposeTheory Theory TheoryMaterials MaterialsProcedure (cited) Procedure (cited OK) ProcedureData/Calculations Raw data/Calculations Raw data/CalculationsData summary (not Necessary) Data summary/ TablesDiscussion (not for all labs) Discussion DiscussionConclusion Conclusion Conclusion
9 Laboratory Notebook Assessment Rubric SLOOrganization1 and 4Purpose and Theory1, 2, 3 and 4Materials, Safety andExperimental Procedure1, 4 and 5Observations, Data,Calculations, andData Sheets1, 2 and 3Discussion, Conclusion1and 2FocusQuestionIs the notebookSufficiently organizedand legible so thatanother scientist canFind informationin the notebook.Understand whatwas done?Can someone elseunderstand why theexperiment was doneand what theory is behind it?Can someone else follow the procedure to repeat the experiment and address safety and disposal?Are records sufficiently detailed so that one can troubleshoot or detect errors?Were the results analyzed critically? Does the conclusion list what was learned in the experiment and/or what can be done next?LEVEL5Each experiment has the required elements of: title, purpose, theory, procedure, observations, data, calculations, discussion, and conclusion. Name on cover and inside of lab notebook; pages sequentially numbered; entries are written in pen, are dated and legible. There is a table of contents.The experiment has (a)clearly stated purpose(s).A detailed explanation ofthe theory behind theexperiment is described,including chemicalreactions, formulas thatwill be used in thecalculations.The notebook provides detailedinformation about the equipment,chemicals, reagents,concentrations, safety anddisposal information.Experimental procedure isprovided or cited. Any changes to the experimental procedure are described.All data, observations, and graphs, are clearly recordedin lab notebook. And allcalculations are shown with appropriate equations and units.Has detailed discussion and summary of results. Conclusions are drawn that correlate to the purpose and show a clear understanding of the experiment.
10 Laboratory Notebook Assessment Rubric 4Most experiments are clearly documented, having all the required elements. Name on cover and inside of lab notebook; pages sequentially numbered; most entries are written in pen (some in pencil); most entries are dated and legible. There is a table of contents.The experiment has (a)clearly stated purpose (s).A sufficient summary andexplanation of the theorybehind the experiment isdescribed, includingchemical reactions,formulas that will be usedin the calculations.The notebook provides adequateinformation about the equipment,chemicals, reagents,concentrations, safety anddisposal information.Experimental procedure isprovided or cited. Anychanges to the experimentalprocedure are described.Most data, observations, and graphs, are clearly recorded in lab notebook. And most calculations are shown with appropriate equations and units.Has adequate discussion and summary of results. Conclusions are drawn that correlate to the purpose and show an adequate understanding of the experiment.3Some experiments are clearly documented, having all the required elements.Name on cover and inside of lab notebook; pages sequentially numbered; some entries are written on one side of the sheet, in pen (most in pencil); some entries are dated and legible. There is no table of contents.The experiment has (a) stated purpose (s) and a tentative explanation of the theory behind the experiment.The notebook provides sufficient information about the equipment, chemicals, reagents, concentrations, safety and disposal information.Experimental procedure is provided or cited.Most data, observations, and graphs, are recorded in lab notebook. And some calculations are provided with appropriate equations and units.Has a discussion. Conclusions are drawn that correlate to the purpose and show an understanding of the experiment.
11 Laboratory Notebook Assessment Rubric 2Few experiments are clearly documented, having all the required elements.One has difficulty finding information in the notebook.Name on cover and inside of lab notebook; pages are not numbered; some entries are written on both sides of sheet in pen (most in pencil). There is no table of contents.Purpose (s) and theory are insufficiently stated.The notebook provides insufficient information about the equipment, chemicals, reagents, concentrations, safety and disposal information.Experimental procedure is provided or cited.Some data, observations, and graphs, are recorded in lab notebook. And some calculations are provided with appropriate equations and units.Has an incomplete discussion and conclusions may not correlate to the purpose. Shows inadequate understanding of the experiment.1Documentation of experiments is sketchy. Some data and results are not recorded. Information is difficult to find.Name on cover and inside of a notebook; pages are not numbered; entries are written on both sides of sheet and in pencil. There is no table of contents.Purpose (s) and theory are unclear or irrelevant.Description of experimental procedure is not cited or safety and disposal information is incomplete.Few data, observations, and graphs, are recorded in lab notebook or calculations are missing.Discussion or conclusions are incomplete or missing. Shows poor understanding of the experiment.
12 Laboratory Notebook Assessment Fundamental and Intro Chem: Students will be at level 3 in the rubric.General Chem I: Students will be at level 4 in the rubricGeneral Chem II and higher: Students will be at level 5 in the rubric.Each year assessment is done for one of the activities/columns in the rubric.Results are reported for each course.Summary of all these assessments are reported at the department level.

17 Lecture Courses Assessment Students will answer five multiple choice questions on one of the topic selected by the department.Target is 70% of correct answers.Results are reported for each course.Summary of all the assessments are reported at the department level.
18 Examples of Assessment. Lab Courses Assessment collected on Discussion for three experiments.Results recorded for each course level and program level.Results discussed at the department. If target is reached, we move to the next activity (e.g. data and calculations) if not, we discuss possible reason, restart the assessment and analyze results for next assessment cycle.
