Development of the Biology Card Sorting Task to Measure Conceptual Expertise in Biology

There are widespread aspirations to focus undergraduate biology education on teaching students to think conceptually like biologists; however, there is a dearth of assessment tools designed to measure progress from novice to expert biological conceptual thinking. We present the development of a novel assessment tool, the Biology Card Sorting Task, designed to probe how individuals organize their conceptual knowledge of biology. While modeled on tasks from cognitive psychology, this task is unique in its design to test two hypothesized conceptual frameworks for the organization of biological knowledge: 1) a surface feature organization focused on organism type and 2) a deep feature organization focused on fundamental biological concepts. In this initial investigation of the Biology Card Sorting Task, each of six analytical measures showed statistically significant differences when used to compare the card sorting results of putative biological experts (biology faculty) and novices (non–biology major undergraduates). Consistently, biology faculty appeared to sort based on hypothesized deep features, while non–biology majors appeared to sort based on either surface features or nonhypothesized organizational frameworks. Results suggest that this novel task is robust in distinguishing populations of biology experts and biology novices and may be an adaptable tool for tracking emerging biology conceptual expertise.     

Group Behavior and Learning in Electronic Forums: A Sociotechnical Approach

The term community is widely and often uncritically used to characterize groupings of people who meet in electronic forums (e-forums). The research reported here shows how the casual use of the term community to characterize these groups can actually undermine their transformation into forms of social organization that are justifiably characterized as communities. This article examines how transforming a group into a community is a major accomplishment that requires special processes and practices. Primary data come from a particular project, the Inquiry Learning Forum (ILF), that aimed to develop "communities of practice" (CoPs) among high school science and mathematics teachers through an elaborate dedicated web site. We examine participants' behaviors in some of the differently structured forums within the ILF web site. While the project's developers expected CoPs to develop autonomously, there was no evidence of CoP formation in open public online forums. The article contrasts two approaches to building online communities that differ sharply: "IT-led community development" and "IT-supported community development." The experience of the ILF project shows that IT-led strategies community development strategies are much more difficult to make workable than are the "IT-supported" strategies.     

Identity(ies) Explored: How Journalists’ Self-conceptions Influence Small-town News

Existing literature on community journalism suggests it is worthwhile to theoretically and conceptually examine journalists in small towns. These reporters and editors always wear multiple hats, including news worker, community member, and booster. Therefore, drawing on newsroom observations and interviews, and applying the interpretive lenses of sociology and identity theory, this study examines the self-perceived identities of weekly newspaper news workers, and how those identities influence their news production. Findings across three organizations show that for these journalists, professional identity is intertwined with personal identity as a church member or baseball coach. Simply put, these journalists see themselves as members of the community that their newspaper covers. Their interactions with friends and neighbors are also interactions with sources – and with advertisers. This sense of personal connection further serves as a key motivation to produce meaningful news for their communities, which the author suggests has served as a safeguard to declines in readership for many small-town weekly newspapers.     

Does defending victimized peers put youth at risk of being victimized?

Defending peers who have been bullied is often thought to put defenders at risk of becoming victimized themselves. The study investigated the concurrent and prospective associations between defending and (peer- and self-reported) victimization, and examined popularity and classroom norms as potential moderators. Participants included 4085 Finnish youth (43.9% boys; M_age = 14.56, SD = .75; 97% born in Finland). Concurrently, defending was positively associated with self-reported victimization in classrooms with high bullying-popularity norms (b = .28, SE = .16). Defending was negatively associated with peer-reported victimization in classrooms with high defending-popularity norms (b = −.07, SE = .03). Defending was not significantly associated with future victimization, suggesting that it is generally not a risk factor for victimization.

Signaling organization and stance: academic language use in middle grade persuasive writing

Effective academic writing is accessible to readers because writers follow shared conventions for organization and signal their stance on particular topics; however, few specifics are known about how middle graders might develop knowledge of and use these academic language forms and functions to signal their organization and stance in persuasive essays. This study examined how differences in organization and stance marker use was related to writing quality in 664 persuasive essays written by 176 sixth, seventh, and eighth grade students. Essays were collected in the context of a supplemental vocabulary program, transcribed and analyzed for length by researchers, scored for overall writing quality by a team of teachers, and then coded for markers of organization and stance by researchers. Multilevel modeling results reveal that two specific emergent organizational marker types (evidence markers and code glosses) have statistically significant negative relationships to quality, and the variety of stance markers used is a positive predictor of quality when an interaction with length is included in the model. Findings give insight into the ways students are using organization and stance markers and point toward these language forms and functions as potentially pedagogically-relevant and worth assessing.     

Language- and literacy-learning opportunities in early childhood classrooms: Children's typical experiences and within-classroom variability

The present study examined the language- and literacy-learning opportunities of 400 young children enrolled in 81 early childhood classrooms to address two research aims: (1) to describe typical language- and literacy-learning experiences afforded to young children in classrooms, and (2) to investigate the extent to which young children had different experiences within classrooms. Results revealed that participating children, on average, spent over 18 min, or 20% of their day, learning in key language and literacy domains. Further, our findings highlight considerable between- and within-classroom variability in language- and literacy-learning opportunities and suggest that young children are afforded different experiences in their classrooms, particularly in specific learning domains. Future investigations ought to further unpack classroom educational practices to ensure that all young children develop the requisite knowledge and skills necessary for academic success in kindergarten and beyond.
