Within the framework of social cognitive theory, we examined the motivation of students (14-16 years old) to learn science in their introductory science courses. The students responded to a questionnaire about their intrinsic motivation, self-efficacy, and self-determination. The students also wrote essays about their motivation, and individual interviews were conducted with a representative sample of students. We found that the students' intrinsic motivation, self-efficacy, self-determination, and achievement were related. Consistent with social cognitive theory, self-efficacy was the motivation factor most related to achievement. The Advanced Placement Program (AP) aspirants were higher than nonaspirants in intrinsic motivation, self-efficacy, self-determination, and achievement. Patterns in students' essays and interviews identified inspiring teachers, career interests, and collaborative-learning activities as strong motivators. The findings suggest that science teachers should use social modeling and collaborative-learning activities to foster students' motivation, achievement, AP intent, and interest in science careers.

This qualitative study examined the role of discourse (verbal elements of language) and Discourse (nonverbal elements related to the use of language, such as ways of thinking, valuing, and using tools and technologies) in the process of group knowledge construction of mechanical engineering students. Data included interviews, participant observations, and transcripts from lab sessions of a group of students working on their senior design project. These data were analyzed using discourse analysis focusing on instances of concept negotiation, interaction in which multiple people contribute to the evolving conceptual conversation. In this context, despite instructors' attempts to enhance the collaboration of group members, concept negotiation was rare. In an effort to understand this rarity, we identified themes related to an engineering Discourse, which included participants' assumptions about the purpose of group work, the views about effective groups, and their epistemologies and ontologies. We explore how the themes associated with the engineering Discourse played a role in how and when the group engaged in concept negotiation. We found that underlying ideologies and assumptions related to the engineering Discourse played both facilitating and inhibitory roles related to the group's conceptually based interactions. © 2004 Wiley Periodicals, Inc.

As colleges and universities aim for greater diversity in their undergraduate populations, one population researchers consider is first‐generation students, or students whose parents do not have a college education. The research reported here addresses first‐generation college students' discipline of study (e.g., biology) and its impact on their persistence. Exploring how female, low‐income, first‐generation college students evaluate their persistence within undergraduate science learning environments contributes to understanding how gender and social class influence persistence in STEM fields. Two White, female, low‐income, first‐generation college students were interviewed during their last year in college. Using constant comparative coding methods and Ricoeur's (Ricoeur [1984] Time and narrative, Volume I (K. McLaughlin & D. Pellauer, Trans.). Chicago, IL: The University of Chicago Press) description of narrative construction, common tensions were identified related to participants' descriptions of undergraduate science as competitive. These persistence‐related tensions are (1) differing experiences in lecture and lab, (2) managing time to work, study, and maintain family relationships, and (3) weighing their personal (family) priorities against the longer time it would take them to reach their science‐related career goals. These tensions depict a traditional undergraduate science learning environment focused on individuals and abstract knowledge that positions female lower‐income students as “academic non‐competitors” because of the importance of kinship ties and physical skills in their cultural background (Lareau [2002] American Sociological Review 67(5), 747–776; Lareau [2003] Unequal childhoods: Class, race, and family life. Berkeley: University of California Press). The participants' experiences support that the gendered and classed expectations needed to succeed in a science environment could be somewhat alleviated through reforms to traditional lecture and laboratory undergraduate science courses that promote cooperative student learning groups and integration of lecture with hands‐on activities. © 2013 Wiley Periodicals, Inc.
