Biology 490:   Research Design and Methods  Prerequisites: Biol 211A; B with grade C or better. This class is a requirement for students who wish to complete the Honors Degree in the Biological Sciences Program at CSULB. An overview of the methodologies and technologies that are available to scientists for the elucidation of life processes. Students will be expected to have gained the necessary skills to design, initiate and successfully complete research experiments using appropriate designs and methodologies that best address and answer the questions posed by hypotheses. Individual research paper on the design, methodology and predicted results of their senior research thesis is required. (Lecture 3 hours).
