Building on Each Other’s Ideas: A Social Mechanism of Progressiveness in Whole-Class Collective Inquiry

In recent decades, important advances have been made in understanding how discursive symmetry can be achieved in whole-class dialogue. However, very little is known about how this dialogue may progress in the sense of critically linking ideas in coherent lines of collective inquiry. This article investigates this issue by analyzing 4 consecutive sessions of a science class with children ages 8 to 10 and identifies a social mechanism that can explain the emergence of progressiveness in collective inquiry. The identified mechanism consists of a series of iterations of the sequence (Direction) → Inference ? Observation ? Consensus → Fixation. This sequence enables the transition from local to collective agency and meaning. Direction creates a gap in a semantic structure, leading to the local formation of an inference. This inference then escalates through observation and consensus before finally being fixed through the creation of an artifact that reifies it as a collective meaning. Based on this collective meaning, a new direction leads to a new local inference, and the cycle begins again.     

Why Do Universities Compete in the Ratings Game? An Empirical Analysis of the Effects of the U.S. News and World Report College Rankings

Previous research has concluded that an institution's ranking in the annual U.S. News and World Report Best Colleges issue impacts admission outcomes and pricing decisions at schools in the Consortium for Financing Higher Education. This article expands on the previous work by analyzing the effects of the U.S. News and World Report rankings across a broader range of universities and variables. The results show that many schools' admission outcomes are responsive to movements in the rankings; however changes in rank are more significant at certain locations in the rankings and affect public and private schools differently. The results also show that the socioeconomic and racial demographics of highly ranked universities may also be affected by changes in rank.     

Identifying and developing crosscutting environmental education outcomes for adolescents in the twenty-first century (EE21)

Abstract

While multiple valid measures exist for assessing outcomes of environmental education (EE) programs, the field lacks a comprehensive and logistically feasible common instrument that can apply across diverse programs. We describe a participatory effort for identifying and developing crosscutting outcomes for Environmental Education in the twenty-first Century (EE21). Following extensive input and debate from a wide range of EE providers and researchers, we developed, tested and statistically validated crosscutting scales for measuring consensus-based outcomes for individual participants in youth EE programs using confirmatory factor analysis across six unique sites, including two single-day field trip locations, four multiday residential programs and one science museum in the United States. The results suggest that the scales are valid and reliable for measuring outcomes that many EE programs in the United States can aspire to influence in adolescent participants, ages 10–14.     

Can massive communities of teachers facilitate collaborative reflection? Fractal design as a possible answer

This paper explores the possibility that virtual communities of teachers with large numbers of members (referred to as massive communities of teachers) can offer support to novice teachers by means of collaborative reflection. The paper examines and conceptualises some problems found in professional massive communities and proposes that massification can dilute what some authors have called social presence or engagement. It is argued that this dilution, among other problems, very much hinders collaborative reflection among members of the community. Collaborative reflection is argued to be a crucial part of the support that novice teachers need in their first years in the profession. Therefore, a challenge is envisioned for massive communities of teachers to avoid the dilution of social presence or engagement. The authors argue that this dilution can be overcome by the use of multiple layers within a platform, referred to as fractal design.     

Cognitive Development and Learning: Analyzing the Building of Skills in Classrooms

This article explores the unique and personal experience of learning within a broader framework of development called skill theory. The framework offers a perspective for recognizing within a diversity of experiences a stable order of increasing complexity in skills that individuals display as they execute or demonstrate changes in their understanding. This order is described in terms of a scale, or ruler, that quantifies across domains the achievement of greater levels of complexity in ability. In particular, we explore the process adults follow as they attempt to understand and apply ideas from science and leadership to allow the reader to witness how individual experiences can map onto a "universal" scale of learning and development.     

Learning via direct and mediated instruction by deaf students

Four experiments investigated classroom learning by deaf college students receiving lectures from instructors signing for themselves or using interpreters. Deaf students' prior content knowledge, scores on postlecture assessments of content learning, and gain scores were compared to those of hearing classmates. Consistent with prior research, deaf students, on average, came into and left the classroom with less content knowledge than hearing peers, and use of simultaneous communication (sign and speech together) and American Sign Language (ASL) apparently were equally effective for deaf students' learning of the material. Students' self-rated sign language skills were not significantly related to performance. Two new findings were of particular importance. First, direct and mediated instruction (via interpreting) were equally effective for deaf college students under the several conditions employed here. Second, despite coming into the classroom with the disadvantage of having less content knowledge, deaf students' gain scores generally did not differ from those of their hearing peers. Possible explanations for these findings are considered.     

Using an Approximate Chi-Square Statistic to Test the Number of Dimensions Underlying the Responses to a Set of Items

An approximate χ² statistic based on McDonald's (1967) nonlinear factor analytic representation of item response theory was proposed and investigated with simulated data. The results were compared with Stout's T statistic (Nandakumar & Stout, 1993; Stout, 1987). Unidimensional and two-dimensional item response data were simulated under varying levels of sample size, test length, test reliability, and dimension dominance. The approximate χ² statistic had good control over Type I errors when unidimensional data were generated and displayed very good power in identifying the two-dimensional data. The performance of the approximate χ² was at least as good as Stout's T statistic in all conditions and was better than Stout's T statistic with smaller sample sizes and shorter tests. Further implications regarding the potential use of nonlinear factor analysis and the approximate χ² in addressing current measurement issues are discussed.     

Anatomical knowledge gain through a clay‐modeling exercise compared to live and video observations

Clay modeling is increasingly used as a teaching method other than dissection. The haptic experience during clay modeling is supposed to correspond to the learning effect of manipulations during exercises in the dissection room involving tissues and organs. We questioned this assumption in two pretest–post‐test experiments. In these experiments, the learning effects of clay modeling were compared to either live observations (Experiment I) or video observations (Experiment II) of the clay‐modeling exercise. The effects of learning were measured with multiple choice questions, extended matching questions, and recognition of structures on illustrations of cross‐sections. Analysis of covariance with pretest scores as the covariate was used to elaborate the results. Experiment I showed a significantly higher post‐test score for the observers, whereas Experiment II showed a significantly higher post‐test score for the clay modelers. This study shows that (1) students who perform clay‐modeling exercises show less gain in anatomical knowledge than students who attentively observe the same exercise being carried out and (2) performing a clay‐modeling exercise is better in anatomical knowledge gain compared to the study of a video of the recorded exercise. The most important learning effect seems to be the engagement in the exercise, focusing attention and stimulating time on task.

Social Capital, Financial Knowledge, and Hispanic Student College Choices

Hispanic students are significantly over-represented in community colleges compared to White and Black students. This paper uses a powerful but underutilized statistical technique, the Oaxaca decomposition, to explore the impact of social capital, as manifested through college financial information, on Hispanic student enrollment in 4-year and 2-year programs. Background differences between the groups were found to have only a small effect on the gap in attending 4-year schools, while the effect of differential returns to these background characteristics was strong and significant. The analysis revealed that some variables of college financial information contribute significantly to the gap.
