三、教学内容(四号黑体)
(具体描述各章节教学目标、教学内容等。实验课程可按实验模块描述)
第一章 the atomistic model of matter and the role of energy in transformations
(小四号黑体)
1.教学目标 Describe fundamental chemical concepts and principles, including: three dimensional molecular structure, kinetics and reaction mechanisms, and equilibria/free energy as applied to organic chemistry, acid-base chemistry, and electrochemistry.
2.教学重难点 Solve a wide variety of integrative chemistry problems that connect ideas across topics, such as the prediction of battery voltages with time.
3.教学内容 Apply submicroscopic models of matter to explain observed macroscopic phenomena, including: chemical and physical characteristics of organic molecules, activation energies of chemical reactions, chemical processes favored or disfavored by entropy, and flow of electrons and ions between electrochemical cells
4.教学方法 Visualize and apply chemical and mathematical models to determine reaction rates, to predict equilibrium concentrations of chemical species before and after system disturbances, to deduce the spontaneity of chemical processes, and to calculate the voltages of electrochemical cells
5.教学评价Design, conduct, and analyze experiments pertaining to organic synthesis, kinetics, equilibrium, thermodynamics, acid/base chemistry, and electrochemistry while augmenting fundamental safety and analysis practices.
第二章 operate as a scientist by learning how to think logically
1.All matter is comprised of atoms; atoms are made of subatomic particles (protons, neutrons, and electrons).
2.Atomic structure and molecular structure affect chemical and physical properties of atoms, molecules, and ions
3.Forces of attraction / repulsion exist between subatomic particles, between individual atoms, and between molecules; these forces, along with structure, influence chemical and physical properties.
4.Atoms, molecules, and ions are in constant motion and possess kinetic energy; kinetic energy influences how often atoms, molecules, and ions collide into and therefore interact with each other
5.Chemical bonds and intermolecular attractions can be broken and reformed; equilibrium occurs when these two processes occur at the same rate.
6.Breaking chemical bonds (and/or overcoming intermolecular forces) consumes energy; making bonds releases energy.
第三章Strategies/ communicate effectively, and solve problems methodically
1.Understand reaction mechanisms and how they lead to rate laws.
2.Determine whether equilibrium has been established and calculate equilibrium concentrations.
3.Understand the difference between nuclear reactions and chemical reactions
4.Understand the difference between Voltaic (galvanic) and electrolytic electrochemical cells.
5.Understand simple organic reactions like substitution, addition, elimination, free-radical and polymerization.
