Immediate Effects of a School Readiness Intervention for Children in Foster Care

Research Findings: School readiness is a strong predictor of adjustment in elementary school and beyond. Children in foster care are at particular risk for academic and social difficulties in school. Limitations in self-regulatory skills and caregiver involvement among these children might contribute to a lack of school readiness. This study presents the immediate effects on school readiness of a targeted, short-term intervention designed to improve children's early literacy, prosocial, and self-regulatory skills during the summer before kindergarten entry: Kids in Transition to School. Using a randomized controlled trial design, we assigned 192 children in foster care to either an intervention or services as usual comparison condition. Multimethod, multi-informant assessments were conducted immediately prior to and following the completion of the intervention. The results from structural equation modeling indicated that the intervention had significant positive effects on early literacy and self-regulatory skills. Practice or Policy: An efficacious, short-term, readily scalable, theoretically based intervention targeted at specific vulnerabilities for children in foster care may help to improve the school readiness and eventual school adjustment of these children.     

Concept map engineering: methods and tools based on the semantic relation approach

The purpose of this study is to develop a better understanding of technologies that use natural language as the basis for concept map construction. In particular, this study focuses on the semantic relation (SR) approach to drawing rich and authentic concept maps that reflect students’ internal representations of a problem situation. The following discussions are included: (a) elaborate classifications of concept map approaches that use natural language responses (e.g., student essay); (b) the SR process of eliciting concept maps, established using studies on domain ontology; and (c) a more effective way to identify key concepts and relations from a concept map generated by the SR approach. By comparing the SR approach to other promising concept map technologies that constrain the analytical process in various ways, this study suggests that the SR approach is likely to draw richer and more authentic concept maps. In addition, this study suggests that a certain combination of graph-related metrics be used to filter key concepts from a SR concept map drawn from a written text of 350–400 words. The methods suggested in the study could be used to design an automated assessment technology for complex problem solving and to develop adaptive learning systems.     

The development and implementation of a web-based formative peer assessment system for enhancing students’ metacognitive awareness and performance in ill-structured tasks

An assessment was conducted of a web-based formative peer assessment system (WFPAS) emphasizing learners’ metacognitive awareness for their performance in ill-structured tasks. Results indicate that the WFPAS group achieved significantly higher scores for metacognitive awareness and performance in ill-structured tasks than the traditional peer assessment group and that a traditional peer assessment group achieved higher scores for metacognitive awareness than a self-assessment group. In addition, the WFPAS group showed significantly higher scores in motivation than the traditional peer assessment group. Results are explained from the perspective of peer interaction and scaffolding. The potential challenges and implications of the WFPAS are discussed.     

Comparing learning outcomes of video-based e-learning with face-to-face lectures of agricultural engineering courses in Korean agricultural high schools

This study investigated the effectiveness of e-learning by comparing the learning outcomes in conventional face-to-face lectures and e-learning methods. Two video-based e-learning contents were developed based on the rapid prototyping model and loaded onto the learning management system (LMS), which was available at http://www.greenehrd.com. Eighty-five Korean agricultural high school students were randomly assigned into the two groups: face-to-face lecture (control group), and video-based e-learning (experimental group). The students of the experimental group logged onto the LMS in the school computer lab and completed each e-learning module. All students were required to take a pretest and posttest before and after learning under the direction of the subject teachers. One-way analysis of variance (ANOVA) was used to examine any difference between the two groups in terms of learning outcomes. One-way analysis of covariance (ANCOVA) was also administered to verify whether there was any difference between the two groups after controlling for the covariate variable: pretest score. According to the results, e-learning resulted in better learning outcomes than face-to-face lecturing. These findings suggest that the use of well designed and appropriately applied e-learning could be worthy even in agricultural education, which stresses hands-on experience and lab activities. Further research should focus on a different e-learning content type in different agricultural subject fields and its relationship with learning outcome.     

When the Rules of Discourse Change,but Nobody Tells You: Making Sense of Mathematics Learning From a Commognitive Standpoint

The interpretive framework for the study of learning introduced in this article and called commognitive is grounded in the assumption that thinking is a form of communication and that learning mathematics is tantamount to modifying and extending one's discourse. These basic tenets lead to the conclusion that substantial discursive change, rather than being necessitated by an extradiscursive reality, is spurred by commognitive conflict, that is, by the situation that arises whenever different interlocutors are acting according to differing discursive rules. The framework is applied in 2 studies, one of them featuring a class learning about negative numbers and the other focusing on 2 first graders learning about triangles and quadrilaterals. In both cases, the analysis of data is guided by questions about (a) features of the new mathematical discourse that set it apart from the mathematical discourse in which the students were conversant when the learning began; (b) students' and teachers' efforts toward the necessary discursive transformation; and (c) effects of the learning–teaching process, that is, the extent of discursive change actually resulting from these efforts. One of the claims corroborated by the findings is that school learning requires an active lead of an experienced interlocutor and needs to be fueled by a learning-teaching agreement between the interlocutor and the learners.     

Guest Editor's Introduction: Analyzing Tools: Perspectives on the Role of Designed Artifacts in Mathematics Learning

Concentrating the attention on one aspect makes it leap into the foreground and occupy the square, just as, with certain drawings, you have only to close your eyes and when you open them the perspective has changed. (Calvino, 1983, p. 7)     

Getting to Evo-Devo: Concepts and Challenges for Students Learning Evolutionary Developmental Biology

To examine how well biology majors have achieved the necessary foundation in evolution, numerous studies have examined how students learn natural selection. However, no studies to date have examined how students learn developmental aspects of evolution (evo-devo). Although evo-devo plays an increasing role in undergraduate biology curricula, we find that instruction often addresses development cursorily, with most of the treatment embedded within instruction on evolution. Based on results of surveys and interviews with students, we suggest that teaching core concepts (CCs) within a framework that integrates supporting concepts (SCs) from both evolutionary and developmental biology can improve evo-devo instruction. We articulate CCs, SCs, and foundational concepts (FCs) that provide an integrative framework to help students master evo-devo concepts and to help educators address specific conceptual difficulties their students have with evo-devo. We then identify the difficulties that undergraduates have with these concepts. Most of these difficulties are of two types: those that are ubiquitous among students in all areas of biology and those that stem from an inadequate understanding of FCs from developmental, cell, and molecular biology.     

Science education for sustainability, epistemological reflections and educational practices: from natural sciences to trans-disciplinarity

In this three-part article we seek to establish connections between the emerging framework of sustainability science and the methodological basis of research and practice in science education in order to bring forth knowledge and competences for sustainability. The first and second parts deal with the implications of taking a sustainability view in relation to knowledge processes. The complexity, uncertainty and urgency of global environmental problems challenge the foundations of reductionist Western science. Within such debate, the proposal of sustainability science advocates for inter-disciplinary and inter-paradigmatic collaboration and it includes the requirements of post-normal science proposing a respectful dialogue between experts and non-experts in the construction of new scientific knowledge. Such a change of epistemology is rooted into participation, deliberation and the gathering of extended-facts where cultural framings and values are the hard components in the face of soft facts. A reflection on language and communication processes is thus the focus of knowledge practices and educational approaches aimed at sustainability. Language contains the roots of conceptual thinking (including scientific knowledge) and each culture and society are defined and limited by the language that is used to describe and act upon the world. Within a scenario of sustainability, a discussion of scientific language is in order to retrace the connections between language and culture, and to promote a holistic view based on pluralism and dialogue. Drawing on the linguistic reflection, the third part gives examples of teaching and learning situations involving prospective science teachers in action-research contexts: these activities are set out to promote linguistic integration and to introduce reflexive process into science learning. Discussion will focus on the methodological features of a learning process that is akin to a communal and emancipatory research process within a sustainability scenario.     

Finding autonomy in activity: Development and validation of a democratic classroom survey

This paper developed a Democratic Classroom Survey to measure students’ perceived democratic environment of the classroom. Perceived democratic environment is one of the most important variables for understanding classroom activity and indeed any type of group activity, but actually measuring perceptions in an objective manner has been problematic. We developed the survey items from both a strong theoretical and a practical perspective, with the contention that Pleasing Authority/External Motivation, Performance Orientation, Cooperation/Collaboration, Integrated Activity, and Goals before Trust/Inter-subjective would be important factors for measuring individual students’ perceptions of the classroom along an authoritarian/democratic continuum. Factor analyses (Exploratory followed by Confirmatory analyses) confirmed the structure of the hypothesized subscales, and the good model fit indicated that the survey is valid. Also, correlation analyses with Classroom Community Scale showed good construct validity. Finally, reliability tests for each subscale and split-half reliability tests showed that the survey is a reliable tool to use in college classrooms. Implications and future directions are discussed.     

Exploring teaching concerns and characteristics of graduate teaching assistants

The purpose of the study was to explore a conceptual structure of graduate teaching assistant (GTA) teaching concerns. Results indicated that GTAs experience five distinct, inter-related types of concerns: class control, external evaluation, task, impact and role/time/communication. These ‘teaching concerns’ were further analysed by examining their relationship with the value placed on them by the GTAs and the confidence in dealing with the teaching-related issues of concern. The results revealed that GTAs tend to have concerns about self, task or role/time/communication-related issues when the nature of the concerned issues is perceived as being valuable but challenging. On the other hand, GTAs are more likely to have concerns with impact-related issues when the nature of the issues is perceived as both being valuable and manageable. Several GTA characteristics, such as teaching experience, teacher efficacy, participation in professional development and values on teaching practices, were examined as predictors of GTA teaching concerns.
