Disentangling the Role of Domain-Specific Knowledge in Student Modeling

Research in Science Education - This study explores the role of domain-specific knowledge in students’ modeling practice and how this knowledge interacts with two domain-general modeling...     

Designing learning environments to promote competent lay engagement with science

An important goal of science education is promoting scientific literacy—the competence to interact with science as laypeople to solve problems and make decisions in their personal and community lives. This is made more challenging in an age of increasing science denialism. In this article, we discuss how to design learning environments for science education that can help students attain scientific literacy. We argue that science curricula should encompass lessons with two distinguishable foci. One focus engages students in understanding the reliability of science. The second focus engages students as laypeople interacting with science in the public sphere. We discuss these two curricular foci, presenting examples from our own work on designing and implementing instruction with the first focus.     

Multiple worlds/mismatched meanings: Barriers to minority women engineers

Despite receiving over 55% of U.S. bachelor's degrees in 1996, women earned <19% of engineering degrees. Polynesian and Filipino women compose an almost vanishing percentage of these graduates. Interviews with four minority women who were close to or had recently completed degrees in civil or mechanical engineering reveal issues of class, race, and gender that affect school success in general and science success in particular. They specifically describe how stereotyping can lead to social stratification and unequal academic and occupational expectations. Narratives are interpreted through Butler's sex/gender theories, Bhaba's postcolonial theories of mimicry, Bourdieu's concepts of social capital and habitus, Bakhtin's theory of speech genres, and Stanton‐Salazar's concept of social networks. The results suggest that Grade K–12 educators, especially in elementary grades, need to challenge practices that segregate students into groups that reflect socioeconomic and ethnic status. In addition to content knowledge, teachers need the kind of multicultural preparation that will help them work effectively with diverse students and their families. © 1999 John Wiley & Sons, Inc.

Authentic science experiences as a vehicle for assessing orientation towards science and science careers relative to identity and agency: a response to “learning from the path followed by Brad”

This response draws from the literature on adaptive learning, traditional ecological knowledge, and social–ecological systems to show that Brad’s choice is not a simple decision between traditional ecological knowledge and authentic science. This perspective recognizes knowledge systems as dynamic, cultural and historical activities characterized by diverse worldviews and ways of constructing and legitimizing knowledge. Brad’s decision is seen as an example of adaptive learning, identity development and personal/collective agency oriented to increasing tribal influence in resource management decisions and policies. I will conclude that science literacy for all is not served by a transcendent, universal, Western modern view of science.

The employment styles of school principals recruiting beginning teachers

In New Zealand, school principals (headteachers), sometimes with a sub-committee of the school board of trustees, interview and hire their own teachers. This research examined whether school principals exhibit different styles in recruiting beginning teachers. A small group of principals was interviewed and items reflecting their views were then developed and put on cards. The cards were sorted by people familiar with educational vocabulary to enable category setting using Kirkland and Bimmler's GOPA technique. Seventy-one principals then prioritized the items. A k-means algorithm was used to cluster principals with similar responses. Analysis of the clusters suggests that recruiting styles do exist. General compatibility emerged as being most important. This suggests that having schools appoint their own staff may lead to greater diversity between schools and greater conformity within them.     

The Human Face Becomes Mapped as a Sensorimotor Reaching Space During the First Year

Although recent behavioral and neural research indicates that infants represent the body’s structure, how they engage self-representations for action is little understood. This study addressed how the human face becomes a reaching space. Infants (N = 24; 2–11 months) were tested longitudinally approximately every 3 weeks on their ability to reach to a vibrating target placed at different locations on the face. Successful reaches required coordinating skin- and body-based codes for location, a problem known as tactile remapping. Findings suggest that a functional representation of the face is initially fragmented. Infants localized targets in the perioral region before other areas (ears/temples). Additionally, infants predominantly reached ipsilaterally to targets. Collectively, the findings illuminate how the face becomes an integrated sensorimotor space for self-reaching.     

Looking through the lenses of science literacy and cultural diversity: learning from Helena’s mistake

Maria Andrée focuses on an immigrant student whose error in a laboratory activity leads to a novel, colorful outcome that she excitedly shares with peers. After engaging in class activities for a few weeks she returns to her earlier dislike of science, saying: "I hate science, particularly Chemistry." The classroom activity system focused on reproduction of school knowledge did not expand to accommodate Helena's “new activity system with an object of learning science.” This essay suggests teachers be prepared to teach diverse students in ways supporting multiple ways to engage in science. This becomes possible when teachers view their classrooms as dynamic, participatory activity systems that support content mastery as contributing to but not being identical to science identity and science literacy.
