This study used a quasi-experimental design to examine the effects of argumentative writing on non-science majors' conceptual understanding and the growth of their writing skills over a semester. To assess gain in conceptual knowledge, tests were given before and after the course; students in the writing group gained significantly more than…

This short-term longitudinal study examined antecedents (academic achievement and achievement goal orientations) of undergraduates' cost perceptions, and the relations between cost perceptions and later achievement. Two waves of data were collected in one semester from 86 diverse students enrolled in a general education biology course for…

Hardy-Weinberg (HW) equilibrium and its accompanying equations are widely taught in introductory biology courses, but high math anxiety and low math proficiency have been suggested as two barriers to student success. Population-level Punnett squares have been presented as a potential tool for HW equilibrium, but actual data from classrooms have…

As discipline-based astronomy education researchers become more interested in experimentally testing innovative teaching strategies to enhance learning in undergraduate introductory astronomy survey courses ("ASTRO 101"), scholars are placing increased attention toward better understanding factors impacting student gain scores on the…

To develop a more scientifically literate society, students need to understand the nature of science, which may be affected by controversial topics such as evolution. There are conflicting views among researchers concerning the relationships between understanding evolution, acceptance of evolution, and understanding of the nature of science. Four…

Undergraduate students enrolled in an introductory biology course for nonmajors during the fall semester of 2007 were administered the Biology Attitude Scale (Russell and Hollander 1975), a constructed Mathematics Attitude Scale, and a portion of the Motivated Strategies for Learning Questionnaire (Pintrich and Smith 1993). Together, the…
