- VII. Required Course Content and Direction
Students seeking a career in Chemical Laboratory Technology should be advised to enroll in this course as soon as the prerequisite is completed. This step will benefit the students because they will be provided with an orientation to career opportunities and occupational skills required of the chemical technician.
Students who enroll in this program are seldom aware of the variety of employment opportunities available to the trained chemical technician in the Delaware Valley. In order to prepare themselves adequately for rewarding careers in this occupation area, students need to become informed of the role chemical technicians have in various chemical operations, such as research and development, pilot plant, production, quality control, and technical sales. Only then can the students seek to match their interests and abilities with the occupation skills required and, thus, make a suitable career choice.
Chemistry, as one of the Natural Sciences, has evolved out of careful observation and experimentation; as technology evolves, so does the body of chemical knowledge. This course will integrate relevant technological advances and their impact in the formulation of chemical principles and their applications. Furthermore, the laboratory component of the course will help to illustrate and apply some of these technological advances.
The course content will revolve around what an employer may expect of the trained chemical technician. This includes attitude, as well as knowledge and skills associated with laboratory experimentation. Students will be taught how to process data, using standard computer programs, to plan and organize the assigned work, to keep accurate and complete records of the experimentation performed, to write a report of the results obtained following procedures established by others, to search the chemical literature for answers dealing with questions and problems encountered in the carrying out of the work assignment, to exercise safe practices in the handling and use of chemicals and equipment, to deal with common laboratory emergencies, such as fire, explosion, and first-aid for injured personnel.
Course Learning Goals
- demonstrate a qualitative understanding of the causal relationships and predictability of all chemical phenomena based on the existence of natural laws;
- describe and explain the sequence of steps used to analyze and solve a quantitative chemical problem in a laboratory setting:
- demonstrate basic skills dealing with techniques of measurement,
- perform necessary laboratory techniques required in the conduct of experiments, and
- interpret the results of observations, including making an assessment of experimental uncertainties in measurements;
- recognize and locate suitable sources of chemical knowledge and scientific information; and read, understand, and interpret this information in verbal, mathematical, and graphical forms;
- apply basic mathematical methods, including arithmetic and algebra to yield pertinent numerical results; and
- describe the role of chemical technicians in different chemically-related industries and in a variety of chemical operations.
