General Education Information Approved College Associate Degree GE Applicability CSU GE Applicability (Recommended-requires CSU approval) Cal-GETC Applicability (Recommended - Requires External Approval) IGETC Applicability (Recommended-requires CSU/UC approval) Articulation Information CSU Transferable UC Transferable Methods of Evaluation Essay Examinations Example: On an exam a student is asked to explain, in writing, how adding a "common" ion would affect the solubility of a different specific compound (product or reactant). Objective Examinations Example: On an objective examination (unit exam), the student is asked to calculate the solubility of barium phosphate in water taking into account the basic nature of the phosphate ion and its related reactions with water. Problem Solving Examinations Example: As part of a unit exam a student is asked to analyze how multiple different procedural skills would affect the results of an experiment they are familiar with. For example "explain how would misreading the buret due to a parallaxis error would affect the result for molarity in the standardization portion of a titration." Projects Example: Students are asked to complete a forensics project in which they design, write and perform laboratory procedures to match samples from a mock crime scene with samples taken from mock suspects. Reports Example: Students are asked to complete an organized report containing pertinent calculations, statistical analysis and discussion of results for each lab, for example Gravimetric analysis of Chloride. Skill Demonstrations Example: Students demonstrate laboratory skills needed to titrate a hard water sample with EDTA to determine the concentration. Repeatable No Methods of Instruction Laboratory Lecture/Discussion Distance Learning Lab: Instructor provides a basic procedure for gravimetric analysis and introduces the concept of gravimetric analysis using lecture and/or multimedia presentation and class discussion. Students edit this basic procedure, adding their own understanding, to produce a more robust procedure that they will use to complete the experiment. This might include diagrams and/or calculations pertaining to the amount of chemicals needed or necessary dilutions. The instructor then reviews the student procedure and oversees the students perform the laboratory experiment based on the procedure that each student prepared. Students perform the experiment and collect qualitative and quantitative data. Students adjust procedure and techniques accordingly with the support of the instructor who facilitates critical thinking. When the analysis is finished, students perform calculations to determine the unknown concentration. Students complete a written or typed formal lab report that contains example calculations, results and discussion of systematic and random errors and a statistical analysis of the trials performed. Students are evaluated on their ability to perform glassware techniques, identify procedural errors, and perform necessary calculations. (Lecture objectives 1-6, 13, 28 and lab objectives 1,2,4,9) Lecture: Instructor presents the topic of uv/vis analysis using lecture, multimedia presentation. This presentation builds on a prior lesson about calibration curves and error analysis of calibration curves. The instructor demonstrates the use of a spectrometer to find absorbance of a solution. The students use prior learning to perform calculations and propose (in writing) a procedure to make standard solutions. The instructor and students discuss the proposed procedure and the instructor suggests modifications if needed. The students make their standard solutions and create a calibration curve, then use statistical analysis to decide if any calibration points need to be re-analysed. The students analyse a mixture of unknown concentration and use the calibration curve to determine the concentration. Students are evaluated on their ability to perform volumetric glassware techniques, determine limitations of calibration curves using error analysis, produce a usable calibration curve and ability to perform necessary calculations. (Lecture objectives 1,2,3,4,7,8, and 27 and lab objectives 1, 2, 3, 8, 9) Distance Learning Instructor presents the topic of uv/vis analysis by either recording a lecture and posting it on the LMS or by using an online meeting program to present the information to the students. This presentation builds on a prior lesson about calibration curves and error analysis of calibration curves. The instructor shows examples of current instruments and explains how they would be used to find absorbance of a solution. After the presentation (or watching the video) students use prior learning to perform calculations and propose a procedure to make standard solutions as a discussion board assignment . The instructor then either uses the discussion board format or online class meeting time to discuss the proposed procedures and the instructor suggests modifications if needed. The instructor then provides the students with mock standard solution data and data for an unknown. The students use their mock data to create a calibration curve and use the calibration curve to determine the concentration of the unknown. Students also perform a statistical analysis of the calibration curve to determine possible systematic errors and the effect of those errors on the result of the unknown concentration, including suggesting ways to minimize those errors. This is done as a written assignment similar in format to on ground assignments in the laboratory notebook. Students are evaluated on their ability to determine limitations of calibration curves using error analysis, produce a usable calibration curve, depth of problem solving skills and ability to perform necessary calculations.
