This evaluation plan describes the procedures that will be used to evaluate the Spectroscopy of Atoms lab and its addition to the General Chemistry 1 course. This course is an entry-level chemistry course for those interested in natural sciences, pre-medicine, and engineering. Currently, there are no non-major chemistry options available, so this course fulfills a need for science requirements in the college. The background of the module, the purposes of the evaluation, the intended decisions and questions, the proposed methods and instrumentation, the selected sample and inherent limitations, logistics and timeline, and the budget for the evaluation are included in this ...view middle of the document...
This lab will replace one covering the conservation of mass, and replaces it with spectroscopy, a topic not previously explained in other activities. Previous semester evaluations and data suggest that student scores and understanding should increase with the addition of this new lab.
Summary of the lab:
The student will use a spectroscope to look at Helium and Hydrogen emission lines. The helium calibrates the spectrometer, and the hydrogen compares experimental vales to the ordinal values. A colored solution (dye mixed with unknown chemicals) is dropped on glow in the dark paper (which is then absorbed). The students expose the solution-saturated paper to light, and specific colors will glow because of the way light behaves as a particle and a wave.
The course lectures clarify concepts from the textbook and teach students problem solving skills. Homework assignments and pre-lab questions are submitted online. Students are required to purchase a key for the online homework software. Doctoral faculty members that specialize in Chemical education teach the course.
The purpose of this evaluation is to collect timely and accurate data for use by the decision makers in the general chemistry division related to the implementation of a new lab in future semesters of the general chemistry 1 course. The strategies implemented in planning this lab include the fact that it should be reliable, inexpensive, safe, and easy to implement. This is a summative evaluation used to assess the effectiveness of the new lab within the general chemistry course.
• To collect information from the target audience, student enrollees, regarding applicability and effectiveness.
• To collect information from experts in the area of chemistry regarding the appropriateness and functionality of the newly instituted lab activity.
Primary Audience and Stakeholders
The director of undergraduate chemistry, Dr. H, the lab manager, Ms. B, graduate teaching assistants, and the students are the primary stakeholders. Relevant secondary stakeholders include the supporting faculty for this course and coordinators of the other lab courses offered to undergraduates.
The designer and implanters of this evaluation is JoAnn DeSalvatore, a student in TLT 476 Assessment of Instructional Technology, with the guidance of Dr. Amankwatia, the course instructor.
Decisions and Questions
The client to inform major decisions regarding the implementation of this lab will use this evaluation.
These are the assumed decisions:
• Is this a lab that should be used in future semesters?
• It is applicable and appropriate to students enrolled in general chemistry?
• Did they perceive that they have learned more or new information because of this additional lab?
• Pre and post test questions
• Did they enjoy doing the new lab?
• It is relevant for current major or future career path.
• What is their...
