Gender Differences in Science: An Expertise Perspective

The purpose of this paper is to propose a new approach to research on gender differences in science that uses the work on expertise in science as a framework for understanding gender differences. Because gender differences in achievement and participation in the sciences are largest in physics, the focus of this review is on physics. The nature of expertise is first discussed and a framework that focuses on factors that influence the emergence of expertise in physics is presented. This is used to interpret what is known about gender differences in science, particularly physics. Next, the potential contributions of the research on gender differences to our understanding of expertise are discussed. Using what is learned from these two areas of research, recommendations are made for future research examining gender differences in physics. It is suggested that such an approach be used for other areas of science, such as chemistry, where large gender differences in achievement and participation also exist.     

Classroom Community and Peer Culture in Kindergarten

This study reflects a naturalistic, interpretive 5-month study in a public school morning kindergarten regarding the children’s social development and creation of a peer culture during the transitional months into public education. The main focus of the research was the children’s perspectives on these transitions and their evolving classroom community and peer culture in response to the teacher, classroom and school environment. This study captures the dynamic and complex flow of activity that occurs in classrooms, the give and take of relationships, and the agency that children take in developing peer culture as one piece of community. Elements of the peer culture that are foregrounded include secondary adjustments as realized in clean-up strategies, protecting play materials over time, and hypothetical competition with the afternoon kindergarten class.     

Anatomy as a Model Environment for Acquiring Professional Competencies in Medicine: Experiences at Harvard Medical School

Anatomy education provides students with opportunities to learn structure and function of the human body, to acquire professional competencies such as teamwork, interpersonal skills, self-awareness, and to reflect on and practice medical ethics. The fulfillment of this wide potential can present challenges in courses that are part of an integrated curriculum and shorter than traditional courses. This new reality, together with students' increasing concern about the stresses within medical education, led to efforts at Harvard Medical School to implement practical steps toward an optimal learning environment in anatomy. These were based on core elements of ethical anatomy education and principles of trauma-informed care. Anatomy is conceptualized here as the “first clinical discipline,” with relational interactions between anatomical educators, medical students, and body donors/patients. Essential prerequisites for the implementation of this work were support by the medical school leadership, open partnership between engaged students and faculty, faculty coordination, and peer-teaching. Specific interventions included pre-course faculty development on course philosophy and invitations to students to share their thoughts on anatomy. Student responses were integrated in course introductions, combined with a pre-dissection laboratory visit, an introductory guide, and a module on the history and ethics of anatomy. During the course, team-building activities were scheduled, and self-reflection encouraged, for example, through written exercises, and elective life-body drawing. Students' responses to the interventions were overall positive, but need further evaluation. This first attempt of a systematic implementation of an optimal learning environment in anatomy led to the identification of areas in need of adjustment.     

Community-based inquiry improves critical thinking in general education biology

National stakeholders are becoming increasingly concerned about the inability of college graduates to think critically. Research shows that, while both faculty and students deem critical thinking essential, only a small fraction of graduates can demonstrate the thinking skills necessary for academic and professional success. Many faculty are considering nontraditional teaching methods that incorporate undergraduate research because they more closely align with the process of doing investigative science. This study compared a research-focused teaching method called community-based inquiry (CBI) with traditional lecture/laboratory in general education biology to discover which method would elicit greater gains in critical thinking. Results showed significant critical-thinking gains in the CBI group but decreases in a traditional group and a mixed CBI/traditional group. Prior critical-thinking skill, instructor, and ethnicity also significantly influenced critical-thinking gains, with nearly all ethnicities in the CBI group outperforming peers in both the mixed and traditional groups. Females, who showed decreased critical thinking in traditional courses relative to males, outperformed their male counterparts in CBI courses. Through the results of this study, it is hoped that faculty who value both research and critical thinking will consider using the CBI method.     

Assessment matters: In search of the wizard of assessment

At first, the shift in measurement of educational success from bodies in seats to learning outcomes sent student affairs educators at California State University, Northridge, into a panic. Persistence, support, and a clear framework for understanding learning led to the discovery that there was a little bit of assessment wizard in all of them.     

Timing in retroactive interference

Retroactive interference is conventionally viewed as attenuated retrieval of a target association due to the training of a second association between training and testing of the target association. In three experiments in which water-deprived rats were used as subjects, we manipulated the durations of the time between cue termination and outcome onset (Experiment 1), the durations of the target and the interfering cues (Experiment 2), and the durations of the outcome used during target and interfering training (Experiment 3). Greater interference was consistently observed between associations bearing a high degree of similarity in their temporal structure, which suggests that interference occurs between complex representations that encode not only the physical attributes of the stimuli, but also their temporal characteristics.     

Cultural cognition and climate change education in the U.S.: why consensus is not enough

Abstract

Integrating climate change into environmental education programs and formal science classrooms can be difficult, as the issue remains controversial and highly politicized among the American public. This study proposes that the same cultural values that shape worldview differences and divide public opinion on anthropogenic climate change will influence if and how science educators support education on the topic. An online survey with quantitative and qualitative measures was distributed among science educators in the southeastern United States to test what, if any, impact cultural cognition has on their opinions about climate change education. The results suggest that respondents’ cultural values have a significant influence on their intentions to support climate change education and preferences for curricula content. The findings also suggest potential avenues for the field of environmental education to develop climate change materials that may help decrease unintentional biases among science educators and more effectively engage their support in teaching its causes and potential solutions regardless of worldview differences.     

Using Games to Engage Students in Inquiry

Abstract

This paper discusses the author’s experiences of getting advanced undergraduate math students to engage in mathematical inquiry by using games as a vehicle for exploration. The students explored the mathematics behind SET^®1, Spot it!^®2, Blokus^®3, and Six^®4. Specifically, we present the experience of the instructor and students and how the games were used to promote and incite inquiry.     

Teachers'' Perceptions of a Learner-Centered Teacher Evaluation System

Promoting success for all students is the driving force to develop and implement sound teacher evaluation systems. As Stronge suggests, the two most frequently cited purposes of personnel evaluation are accountability and performance improvement (1997, p. 3). As a result, researchers are conceiving of teacher evaluation as a mechanism for improving teaching and learning (Danielson and McGreal, 2000). On the other hand, others affirm that the trend in teacher evaluation is toward more self-evaluation and expanding one's teaching repertoire (Association for Supervision and Curriculum Development, 1999, p. 8). However, teachers' voices relative to emerging teacher evaluation trends are missing. Thus, this study explored teachers' perceptions about the support for professional development available to them, the perceived potential benefits of a learner-centered teacher evaluation system to enhance their professional growth, and pitfalls. Only elementary school teachers participated in the study. The researcher analyzed teachers' written responses to open-ended questions, and generated categories by emerging themes to determine teachers' perceptions.Findings of the study suggest that teachers receive support from both campus level and central office level. Teachers also believe that a learner-centered teacher evaluation fosters walk-through observations, opportunities for professional growth, feedback, learner-centered dialogue, a holistic perspective, and teacher self-evaluation. On the other hand, findings suggest that teachers question the labels for each level of performance, and are concerned that the system might be somewhat subjective. Finally, suggestions are made to conduct additional studies to further illuminate teachers' voices associated with teacher evaluation and development at other school levels, and to expand our understanding of emerging teacher evaluation formats which aim at student success.
