Discusses an instructional strategy in which stoichiometric reactions are presented in terms of a recipe. Solutions for two different stoichiometric problems are included. (JN)

Background: The current mode of stoichiometry instruction employs a passive pedagogy that consists of students reading, listening, watching, and memorizing disembodied facts, procedures, and principles in preparation for future application. But chemistry students are often subsequently unable to apply this stoichiometry knowledge in equilibrium…

Describes a sequential problem solving method for teaching stoichiometry to high school students. Provides several sample problems. (CS)

A study was conducted to assess junior and high school students learning achievement in the topic of stoichiometry by using The Student Conceptual Understanding Test (SCUT). The low student achievement on the SCUT test deserves special attention from chemistry teachers, and it is stated that effective teaching strategies to promote student…

The outline for a unit on the chemistry of fitness and nutrition is presented. Topics discussed include the organic basis of life, functional groups, kitchen experiments, micronutrients, energetics, fitness vs. fatness, current topics, and evaluation. This unit reviews the basic concepts of chemical bonding, acid-base chemistry, stoichiometry, and…

Results of a HyperCard method for assessing the performance of expert and novice high school chemistry students solving stoichiometric chemistry problems (balancing chemical equations) is reported. MANOVA results indicate significant difference between expert and novice students solving the five stoichiometric chemistry problems using…

Describes a simple laboratory procedure for changing sodium carbonate into sodium chloride by adding concentrated HCl to cause the reaction and then evaporating the water. Claims a good stoichiometric yield can be obtained in one three-hour lab period. Suggests using fume hood for the reaction. (ML)

Presents two different approaches to teaching stoichiometry. One uses a question and answer technique and the familiar concepts of "pounds" and "degrees" to describe the concept. The second example introduces stoichiometric relationships used in the well-known camper's snack known as S'mores. (TW)
