Research Problem Integrate Core Concepts and throughout the Biology Curriculum (Vision and Change, AAAS, 2009) Conceptual learning is is an understanding of a topic in different layers of complexity. It is not the factual recall, and it is stored for the longer time. Limited evidence suggests that active learning approach can result in higher student learning gains (Udovic et al. 2007; Knight and Wood, 2005; Freeman et al. 2007). Smith, Wood, and Knight (2008) designed and validated a 25- questions, Genetic Concept Assessment (GCA), which is reliable assessment instrument for the conceptual understanding. Compared to the traditional lecture course, interventions with different pedagogical approaches can result higher level of conceptual learning in undergraduate genetics classes.

Research Question Research Question: (Constructivist theory) Data analysis from the classic (discovery) research papers promotes the conceptual learning in Genetics course. Research Context: Course: Introductory Genetics (Bio 3450; Writing Enhanced), one of the core courses for the Biology major 70 students per semester (Majority of them are juniors) Sam Houston State University: Total students- 19,000 16% African American, 15% Hispanic, 6% Asian, 53% first generation college students. My question is interesting because: It parallels the goal of Vision and Change-A call for action. Conceptual understanding of Intro. Genetics will help learn advance genetics courses.

Research Methodology Research Instrument: Assessment tool: Genetic Concept Assessment (GCA) Inventory (Smith, Wood, and Knight, 2008): Aligned with learning objectives Development tool: Students Survey (1-5 scale): Does data analysis help the learning objectives? reflections, attitude, worked or did not work Both will be submitted to IRB approval. Intervention Molecular genetics will be taught using data analysis, while Mendelian genetics will be taught using traditional lecture method (Internal control). Statistical Analysis Pre-test (Baseline data) and post-test data analysis Average score gain, Comparison of class score (paired sample T-test) H 0 Hypothesis: No difference in test scores between molecular and Mendelian genetics portion of the Genetic Concept test.
