Tutor Versus Peer Group Assessment of Student Performance in a Simulation Training Exercise

The performance of a group of third‐year higher diploma students from the Department of Hotel & Tourism in a simulation training exercise was assessed separately by the tutor and peer group, using an identical checklist. Ninety‐six pairs of tutor and peer group assessment marks were obtained and compared. Results showed that there was some degree of agreement between tutor and peer group markings, although the level of congruence was somewhat less than reported in earlier studies. However, when the tutor and peer group average marks were converted to grades, agreement was found in only 46.9% of the cases and the level of agreement between the two gradings was not statistically significant. Significant differences were also found in the variability of tutor and peer group markings. Furthermore, there were indications that peer group markings tended to be more stringent than tutor markings in the higher mark range, but relatively more lenient in the lower mark range. This trend was particularly obvious when the tutor and peer group marks were converted into grades. Implications of the findings are also discussed.

Memory for everyday information in students with learning disabilities

This study compared students with and without learning disabilities (LD) on their recall of academic information and information encountered in the students' everyday lives. The academic recall measures included a sentence listening span test, a rhyming words working memory test, and a visual matrix working memory task. Students' cued recall of all the tasks was also measured. The everyday working memory tasks included a dance episode event recall test; a library procedure recall test; and recall tests of commonly found objects, such as a coin, a telephone, and a McDonald's sign. Compared to students without LD, students with LD performed poorly on both the academic recall tasks and the everyday recall tasks. These results support the notion that some students with LD may have working memory problems that affect their performance on tasks other than reading. The results of the cued recall showed that the availability of cues significantly decreased the ability group differences on many of the academic and everyday tasks. This result replicates prior research findings that students with LD do not use retrieval strategies effectively and that some students with LD may have a production deficiency that affects their retrieval of previously encoded information.     

Differential effects of three professional development models on teacher knowledge and student achievement in elementary science

To identify links among professional development, teacher knowledge, practice, and student achievement, researchers have called for study designs that allow causal inferences and that examine relationships among features of interventions and multiple outcomes. In a randomized experiment implemented in six states with over 270 elementary teachers and 7,000 students, this project compared three related but systematically varied teacher interventions—Teaching Cases, Looking at Student Work, and Metacognitive Analysis—along with no‐treatment controls. The three courses contained identical science content components, but differed in the ways they incorporated analysis of learner thinking and of teaching, making it possible to measure effects of these features on teacher and student outcomes. Interventions were delivered by staff developers trained to lead the teacher courses in their regions. Each course improved teachers' and students' scores on selected‐response science tests well beyond those of controls, and effects were maintained a year later. Student achievement also improved significantly for English language learners in both the study year and follow‐up, and treatment effects did not differ based on sex or race/ethnicity. However, only Teaching Cases and Looking at Student Work courses improved the accuracy and completeness of students' written justifications of test answers in the follow‐up, and only Teaching Cases had sustained effects on teachers' written justifications. Thus, the content component in common across the three courses had powerful effects on teachers' and students' ability to choose correct test answers, but their ability to explain why answers were correct only improved when the professional development incorporated analysis of student conceptual understandings and implications for instruction; metacognitive analysis of teachers' own learning did not improve student justifications either year. Findings suggest investing in professional development that integrates content learning with analysis of student learning and teaching rather than advanced content or teacher metacognition alone. © 2012 Wiley Periodicals, Inc.

The Effect of School Culture on Science Education at an Ideologically Innovative Elementary Magnet School: An Ethnographic Case Study

This ethnographic case study investigated the science practices of teachers at one public elementary magnet school in light of how school culture influenced science curriculum design and instruction. The purpose of the study was to address how school culture impacted the school??s overall treatment of science as a viable content area. Key informant teachers were interviewed to explore their personal beliefs and values, teaching, access to materials, and views of the adopted integrated thematic curriculum model and magnet structure. The resulting data, triangulated with informal observation and artifact collection, were analyzed using a theoretical framework that emphasized five interdependent school culture indicators (values, beliefs, practices, materials, and problems). Findings suggest that the school??s culture adversely influenced the treatment of science.     

Power Dynamics and Questioning in Elementary Science Classrooms

We describe the dynamic discourse interactions between a teacher and her students in a third-grade science classroom. We focused on how the teacher and students initiate, prompt, respond, and provide feedback; use questioning and power strategies; and how questions are associated with power dynamics. We relate the consequences of teacher use of power to the engagement of student with subject matter. Two classroom sessions were observed and teacher?Cstudent interactions audio recorded. Data were transcribed and a method was developed for analyzing teacher-student interactions, power dynamics, and types of questions asked. Results revealed that teacher talk was twice as frequent as students?? talk; questions were primarily closed-ended and task-oriented; and students asked few questions. The teacher exercised power by keeping activities organized and conventional, and utilizing subject matter. The developed methods showed us the complexity of question and power dynamics in classroom discourse and have implications for professional development and research.     

Trends in culturally relevant interface design features for Latino Web site users

There is a lack of published research on designing Web-based instruction for the adult U.S. Latino population. Instructional designers need guidance on how to design culturally relevant learning environments for this audience, particularly for Latino people from Mexican heritage. The authors used content analysis to investigate the extent to which 20 U.S. state food stamp Web sites and 20 Mexican state government Web sites contained culturally relevant interface features targeted at the Spanish-speaking Latino population. Web sites were coded for 10 features distilled from Hofstede??s work on cultural differences. Results indicated that more culturally and linguistically relevant features, including Hofstede??s dimensions of collectivism, power distance, and uncertainty avoidance, as well as adequacy of information in Spanish, were found on Mexican than on U.S. Web sites. The findings suggest that Hofstede??s cultural dimensions theory might provide a useful framework for designing Web-based resources for the adult U.S. Spanish-speaking Latino population and provides additional evidence to further investigate if Web-based interface features tailored for U.S. Latino Web users motivate users, strengthen communication, and promote learning.     

Developing Children's Early Competencies to Engage With Science

Science educators have long been concerned with how formal schooling contributes to learners’ capacities to engage with science after school. This article frames productive engagement as fundamentally about the coordination of claims with evidence, but such coordination requires a number of reasoning capabilities to evaluate the strength of evidence, critique methods, and other factors upon which evidence evaluation rests, evaluating sources and potential biases, and so on. Although the general discourse on education commonly suggests students are bad at such things, we review cognitive development research that demonstrates children display a variety of capabilities, even at early ages, that can be productively built upon by formal science instruction. We use this research to suggest some possibilities for formal schooling to develop children's capacities for evaluating claims within the pursuit of personally meaningful goals. We conclude with observations of useful directions our analysis opens to research.     

Relationships matter: some benefits,challenges and tensions associated with forming a collaborative educational researcher group

Growing recognition of the complexity of children’s lives has led to strong advocacy in education research literature for greater collaboration between researchers from different paradigms to address the ‘wicked’ problems that face contemporary children and families. There is little literature, however, exploring how collaboration works in practice. This paper, drawing on researcher reflective narrative, and using Cultural Historical Activity Theory as a heuristic framework, describes and critiques the formative stages of an educational research collaborative group of five early and one mid-career early childhood education researchers (the authors), from two universities, and with quite different epistemological and ontological understandings. It outlines, from an insider perspective, some of the outcomes, challenges and tensions associated with participating in the research group, and concludes by providing some implications for policy and considerations for those contemplating forming a collaborative group.
