Teaching and Learning Goals Established by Truman College
Taking a course in Chemistry helps a student achieve all of the following general education goals. How this occurs is explained below.
- Communicate effectively in both written and oral forms
- Gather, interpret and analyze data
- Demonstrate the ability to think critically, abstractly and logically
- Work with a variety of technologies
- Exhibit social and ethical responsibility
- Perform productively in the workforce
- Demonstrate the ability to learn independently
- Gain awareness of their role in the global community
Students will keep a laboratory notebook and learn to record careful observations, draw appropriate conclusions and reflect on what they have learned.
Students will learn to collect data in the laboratory, create graphs, compare quantitative data and draw conclusions about the data obtained.
The Scientific Method is predicated upon deductive and inductive logical reasoning. Students will study applications of the scientific method to information gathered by the scientific community. Students will read articles about chemical discoveries. Abstract thinking is developed in many ways in chemistry from the use of symbols and models to the use of mathematics to solve a variety of problems.
Students use computers, data acquisition equipment, microscopes, digital imaging devices, media, the Internet, podcasts, digital balances, all in the pursuit of scientific knowledge.
This very serious goal is addressed on many levels in the chemistry course, from the discussion of the importance of careful and precise measurements that could affect the life of a patient to the discussion of what happened when the space ship Challenger exploded or a grain elevator explodes - we examine the role of responsible use of chemical knowledge.
Because Chemistry education is comprehensive in utilizing the body (kinesiology), the mind (both spatial and analytical reasoning) and the heart (looking at the connection of chemistry to the world) it is an excellent course to prepare individuals for the workforce.
Students are given independent projects to complete in the course. They are also given questions to research independently. Reporting these results to the class develops their ability to speak confidently to their peers.
By discussing the way that chemistry is connected to other occupations and careers we develop student awareness about their career choice and its dependencies on a basic understanding of chemistry.
- GEG1: The student exhibits social and ethical responsibility and is aware of her or his place in the global community.
- GEG2: The student performs effectively in the workplace and has the ability to work and make effective use of a wide variety of current technologies.
- GEG3: The student communicates effectively in both written and oral formats.
- GEG4: The student demonstrates the ability to think critically, abstractly, and logically.
- GEG5: The student gathers, interprets and analyzes data.
