          Methods of Evaluation

          • Objective Examinations
            • Example: Students will take quizzes and examinations utilizing a variety of objective questions like true or false and multiple choice on solving problems using relationships identified in the periodic table (lecture course objective 14). Standard grading. Example Questions: 1. Group 6 elements tend to gain 2 electrons. True or False? 2. Group 7 elements tend to form ____ bond(s). a. 0 b. 1 c. 2 d. 3 e. none of the above
          • Problem Solving Examinations
            • Example: Students will solve problems utilizing molar masses and stoichiometry (lecture course objectives 12, 15, 17 and 19-21). The calculated results are graded based on work shown to demonstrate the student’s problem solving process and arriving at the correct value, units and significant figures. Rubric grading. Example Question: Solid sulfur reacts with oxygen gas to produce sulfur dioxide gas. Calculate the number of grams of the excess reactant remaining when 25.0 grams of sulfur is mixed with 125 grams of oxygen gas.
          • Reports
            • Example: In the course lab manual, students will collect data, calculate results and answer additional questions regarding the topics demonstrated in the lab like studying and utilizing density, the relationship between mass and volume of a substance (laboratory course objective 4). Students will be graded on precision of measurements and use of units and significant figures, as well as ability to convert data collected into desired results with correct units and significant figures. Example Lab Report: Write up the lab report for the "Density" lab. Example Question, "Density" lab: Using the mass and initial and final volumes of water displaced by a rubber stopper, calculate the volume and density of the rubber stopper.
          • Skill Demonstrations
            • Example: Students will utilize lab equipment to obtain precise and accurate data and results like in the titration lab experiment (laboratory course objectives 1-2, 9-10). Students will be graded on precision and accuracy of data. Example Skill Demonstration:: Titration of vitamin C (ascorbic acid) where students use titrations to accurately determine the concentration of a standard sodium hydroxide titrant using weighed masses of potassium hydrogen phthalate and measured volumes of the titrant necessary to neutralize the acid. The standardized titrant is then used to determine the amount of vitamin C in a vitamin C tablet by titrating a measured mass of vitamin C powder.
