Evaluating two approaches to helping college students understand evolutionary trees through diagramming tasks

To understand evolutionary theory, students must be able to understand and use evolutionary trees and their underlying concepts. Active, hands-on curricula relevant to macroevolution can be challenging to implement across large college-level classes where textbook learning is the norm. We evaluated two approaches to helping students learn macroevolutionary topics. Treatment 1 is a laboratory for the software program EvoBeaker designed to teach students about evolutionary trees. We tested Treatment 1 among nine college-level biology classes and administered pre/posttests to assess learning gains. We then sought to determine whether the learning gains from Treatment 1 were comparable to those derived from an alternate hands-on treatment, specifically the combination of a prerecorded lecture on DVD and paper-based activity based on Goldsmith's Great Clade Race (Treatment 2). Comparisons of pre- and posttests among participants using either Treatment 1 or 2 show large learning gains on some misconceptions and skills beyond knowledge gained from reading standard textbook entries. Both treatments performed equivalently in overall learning gains, though both had areas where they performed better or worse. Furthermore, gains among students who used Treatment 1 representing a wide range of universities suggest that outcomes are potentially applicable to a variety of "real-world" biology classes.     

Effects of Visual Spatial Structure on Textual Conversational Multitasking

Textual computer-mediated communication gives rise to conversational multitasking—participation in several concomitant synchronous textual conversations. This study examined how this communication competence is affected by several visual parameters—the distance between conversation windows, number of windows, and window size. Results show that comprehension of concomitant textual conversations is not affected by the distance between conversation windows, and that the advantage of separating conversation threads into distinct windows is greater when overall window size is larger. This study considers the implications and applications of these results to communicative multitasking phenomena, in general, which become prevalent in technologically advanced societies.     

Learning to teach with technology: authoring practised identities

Over the years there has been a strong urge to incorporate information and communications technology (ICT) in teaching practices; however, the pace of integration has been characterised as disappointing. Teachers’ lack of competence, their resistance and lack of availability and stability of computers and infrastructure have been offered as explanations. The paper advocates sociocultural theory as a fruitful approach in the research on developing teaching practices with ICT. Empirical evidence from the discourses of student teachers and mentors during internship is used to illustrate how practised identities for teaching with ICTs emerge in action through processes of positioning and authoring. An enhanced understanding of the situated interplay of personal and institutional horizons for meaning making could be crucial for the development of programmes for learning to teach with ICT.     

Dare to Dream: New Venture Incubator for Older Adults

The purpose of this article is to describe a project that aims to foster active aging through entrepreneurial activities among older adults. The project establishes the feasibility of implementing an intervention program that assimilates the concept and capabilities of entrepreneurship among older adults and supports them while launching new ventures. A 12-meeting training program was provided to the selected participants followed by continuing support through a tailor-made incubator. The pilot experiment selected a group of retirees who sought work and had no previous entrepreneurial experience. Of the 22 participants in the intervention program, 15 (70%) actually started a microenterprise based on their previously formulated ideas and past work experience and encouraged by participation in the program. Fostering older adults’ entrepreneurial activities has value much further than fulfilling individual needs because it provides benefits to the welfare of the community as well as to the economy. The pilot experiment suggests that this type of intervention program is feasible and warrants further studies.     

Exploring Community College Faculty Perceptions of Student Outcomes: Findings of a Pilot Study

This study explored the paradigmatic differences in perceptions of community college faculty employed at select Virginia and West Virginia community colleges collected via a web-based survey. The study is framed within the faculty self-classification along the “hard” and “social/behavior” science paradigm continuum. Given the paradigmatic continuum, faculty perceptions' of student outcomes were examined. Faculty respondents consistently reported the importance of intellectual growth; however, differences in relative importance of outcomes tied to emotional, cultural, and social growth exist. The potential implications of these perceptions on student experiences and outcomes are considered.     

Teachers “in the making”: Building accounts of teaching

In this paper, mentoring practices during internship in teacher education are identified as boundary activities between schools and universities. By using the notions of common places and accounting practices, the emerging discourses of student teachers and mentors in a Norwegian school are explored to expand our understanding of how conceptual, practical and contextual resources are used to construct justified accounts of experiences. The results of this study indicate that during internship the student teachers learn ways of seeing, representing and talking about their experiences that are deemed relevant within the school's practice, using and transforming resources accordingly.

From Hard to Soft Governance in Multi‐level Education Systems

Decision‐making in educations systems has become more complex: while decentralisation has moved the locus of power to lower governance levels, the central level still is held responsible for the quality of outcomes. As a consequence, new steering strategies have emerged that tend to apply softer modes of governance as opposed to harder ones in the past. This article aims at shedding empirical and conceptual light on these new developments. It compares two national examples for soft modes of governance with a supra‐national one (the EU's Open Method of Co‐ordination OMC) and argues that OMC might be both a useful analytical lens to categorise new steering mechanisms and a possibly promising policy strategy at the national level.
