Description
The nature of an undergraduate, nonmajors biology laboratory was investigated in this study. Student participants were enrolled in a general education biology laboratory course at the University of Northern Iowa. The researcher's purpose was to gain a characterization of the instructional format and laboratory activities experienced by students.
Interpretation of student and instructor responses enabled an insider's view of the biology laboratory. The laboratory period was consistently described by both students and instructors as having three parts, Beginning, Middle, and End, with the End being of special importance for conceptual development. The instructional format of the three instructors differed within the three portions of the laboratory period, ranging from an inquiry-oriented, partial learning cycle to a fairly expository model labeled inform/verify/practice. There was striking similarity in intrasectional student and teacher descriptions of instructional format. Additionally, students experiencing the alternate instructor provided the same characterizations of instructional format as those provided by the instructor's usual students. There were no discernible patterns of instructional format based on sex or reasoning level. In addition to the central role of instructional format, three areas of importance emerged: the social aspects of learning, the collaborative and cooperative nature of laboratory work and learning, and the role of self-efficacy.
Theory developed from and grounded in the data showed six factors important in the introductory college biology laboratory: collaborative and cooperative learning, student-student and teacher-student interactions, attitude and self-efficacy, learning process and learning style, effective instructional format, and science content. These factors were found to be similar to factors identified in the literature as important in K-12 science education. These factors were set in the context of schooling and learning paradigms, paralleling J. J. Schwab's four conditions of a curriculum (subject matter, learners, teachers, and milieus), Benjamin Bloom's model of important factors in student achievement and schooling (cognitive entry behaviors, affective entry behaviors, and quality of instruction), and fitting a constructivist epistemological framework.
