Within the increasing body of research that examines students' reasoning on socioscientific issues, we consider in particular student reasoning concerning acute, open-ended questions that bring out the complexities and uncertainties embedded in ill-structured problems. In this paper, we propose a socioscientific sustainability reasoning…

Research has now demonstrated that students can learn nature of science concepts variously through student-led investigations, contemporary cases, and historical cases. Here we articulate more precisely the merits, deficits, and context of each approach and begin to profile how to integrate them as complementary methods. Emphasis now needs to…

Similar to Dickens's "Tale of Two Cities", this research study is about a tale of two schools. The first type of school is a dysfunctional school. Dysfunctional schools are schools in a state of chaos (Shipengrower & Conway, 1998). The second school is that of order. The researchers refer to this school as a functional school.…

This article investigates the second language (L2) acquisition of two expressions of the semantic feature [definite] in Russian, a language without articles, by English and Korean native speakers. Within the Feature Reassembly approach (Lardiere, 2009), Slabakova (2009) has argued that reassembling features that are represented overtly in the…

Given the current methodological interest in eliciting direct data on the cognitive processes L2 learners employ as they interact with L2 data during the early stages of the learning process, this article takes a critical and comparative look at three concurrent data elicitation procedures currently employed in the SLA literature: Think aloud (TA)…

The present article provides an exploration of ultimate attainment in second language (L2) and its limitations. It is argued that the question of maturational constraints can best be investigated when the reference population is bilingual and exposed on a regular basis to varieties of their first language (L1) that show cross-linguistic influence.…

This study investigates how derivational complexity interacts with first language (L1) properties, second language (L2) input, age of first exposure to the target language, and length of exposure in child L2 acquisition. We compared elicited production of "wh"-questions in French in two groups of 15 participants each, one with L1 English…

In this article, the authors suggest that current notions of advocacy in early childhood education should be expanded to include a view of young children as citizens. The authors ground their discussion in a how-to book project in Providence, Rhode Island, consider different concepts of children and citizenship, share commentary from City Hall and…

Using documentation in professional development has the potential to enhance professional visibility and credibility and to turn attention squarely to learning and teaching. This article targets providers of professional development and offers clear steps to providing an inquiry-based approach using close observation and documentation of…

In the social sciences, latent traits often have a hierarchical structure, and data can be sampled from multiple levels. Both hierarchical latent traits and multilevel data can occur simultaneously. In this study, we developed a general class of item response theory models to accommodate both hierarchical latent traits and multilevel data. The…

Every day, early childhood teachers confront issues, problems, and concerns in their classrooms. Sometimes they do nothing. Sometimes they use trial and error. Sometimes they go to a workshop or read an article. We have found a way to intentionally and systematically research and answer our own questions and to enrich our own professional…

Location, where geographic elements interwork spatially and dynamically, has been one of the enduring themes in geographic studies. There are a number of location theories to explain why things are located where they are. Alfred Weber's location theory stresses that the least cost of delivering products is a key factor in location selection,…

Universal Instructional Design (UID), an approach to curriculum and pedagogy that promotes multiple means of access and expression in the classroom, allows instructors to better prepare diverse learners with twenty-first-century skill sets through nontraditional assignments. However, these nontraditional approaches can be difficult to assess.…

In this study, smoothing and scaling approaches are compared for estimating subscore-to-composite scaling results involving composites computed as rounded and weighted combinations of subscores. The considered smoothing and scaling approaches included those based on raw data, on smoothing the bivariate distribution of the subscores, on smoothing…

This article presents work from an ongoing investigation, where the objective is to understand the impact of recent Portuguese legislation--the Teaching Career Statute and its respective Evaluation of Teacher Performance regulations--on the (re)construction of teacher identity, the teaching career and professional development. From an analysis of…
