Assessing team-based instructional design problem solutions of hierarchical versus heterarchical Web-based hypermedia cases     

Nada Dabbagh  Katrina Denisar 《Educational technology research and development : ETR & D》2005,53(2):5-22

For this study, we examined the cogency, comprehensiveness, and viability of team-based problem solutions of a Web-based hypermedia case designed to promote student understanding of the practice of instructional design. Participants were 14 students enrolled in a graduate course on advanced instructional design. The case was presented to students using two hypermedia structures, hierarchical (tree-like structure) and heterarchical (network-like structure). Results from analyses of four data sources revealed that problem solutions developed in response to the heterarchical case design were more cogent and convincing than problem solutions developed in response to the hierarchical case design. Specifically, the heterarchical case solutions provided evidence of a heuristic problem-solving process facilitating the identification of an expert-like solution to the case and the articulation of learners' understanding and application of grounded and engaging instructional designs.  相似文献   

Understanding number sequences leads to understanding mathematics concepts

Ninety-six first grade students in an urban school system were tested in October and May on reading, mathematics, and their understanding of sequences of letters and numbers. A time lag analysis was subsequently conducted. In such analyses, cross-correlations between the first measurement of one variable and the second measurement of another are compared. The larger of the correlations indicates the direction of the relationship; i.e., which variable is most likely to be causal. Correlations of the fall scores on the number sequences with spring scores on the mathematics concepts scale were significant, while correlations of the fall mathematics concepts scores with spring number sequence scores were negligible. This indicates that understanding such complex sequences has a directional effect on understanding mathematics concepts. Fall–spring cross-correlations for the letter sequences and reading test, although significant, did not differ, and hence provided no indication of the direction of the relationship. Potential explanations were discussed.  相似文献   

The Effects of Rhetorical and Content Subgoals on Writing and Learning     

Perry D. Klein  Katrina N. Haug  Nina Arcon 《Journal of Experimental Education》2017,85(2):291-308

Argument writing is challenging for elementary students. Previous experimental research has focused on scaffolding rhetorical goals, leaving content goals relatively unexplored. In a randomized experiment, 73 students in grades 5, 6, and 7 wrote persuasive texts about difficult-to-classify vertebrates. Each student received one of three sets of writing prompts: a persuasive goal only (control); a persuasive goal + rhetorical-subgoal prompts; or a persuasive goal + content-subgoal prompts. Rhetorical subgoals increased text quality, variety of rhetorical moves, number of complex propositions, and classification knowledge. Content subgoals increased the number of simple propositions in text. A path analysis indicated that content-subgoal prompts and rhetorical-subgoal prompts elicited different paths to writing and learning.  相似文献   

Validation of Automated Scoring for a Formative Assessment that Employs Scientific Argumentation

Scientific argumentation is one of the core practices for teachers to implement in science classrooms. We developed a computer-based formative assessment to support students’ construction and revision of scientific arguments. The assessment is built upon automated scoring of students’ arguments and provides feedback to students and teachers. Preliminary validity evidence was collected in this study to support the use of automated scoring in this formative assessment. The results showed satisfactory psychometric properties related to this formative assessment. The automated scores showed satisfactory agreement with human scores, but small discrepancies still existed. Automated scores and feedback encouraged students to revise their answers. Students’ scientific argumentation skills improved during the revision process. These findings provided preliminary evident to support the use of automated scoring in the formative assessment to diagnose and enhance students’ argumentation skills in the context of climate change in secondary school science classrooms.  相似文献   

Teacher professional development: a different perspective     

Katrina Roseler  Michael W. Dentzau 《Cultural Studies of Science Education》2013,8(3):619-622

Reform in science education is a slow process. Current professional development experiences may slow the process even more if modeled after traditional top down approaches. The common practice of inviting “experts” to deal with specific local issues supports a covert message that classroom teachers are not capable of meeting the challenges of reform with the resources and expertise provided by their immediate community or network. What is being proposed here is not radical but merely an adjustment in thinking about learning at any level. In any given teacher network, the teachers overall are both highly educated in content and pedagogy, it makes sense to allow them the opportunity to address the obstacles of reform and provide assistance when requested; not mandate professional development that may or may not address the needs of teacher, school or district.  相似文献

Primary school children and self harm: the emotional impact upon education professionals,and their understandings of why children self harm and how this is managed     

Rebecca Simm  Katrina Roen  Anna Daiches 《牛津教育评论》2013,39(6):677-692

There is evidence suggesting that self harm among young people is beginning earlier, in childhood and adolescent years. This paper reports on a qualitative study of primary school staff responses to self harm among children. Some studies with adolescents show self harm presents challenges to education professionals who may lack training or resources to address this issue, yet research concerning self harm among primary school children is limited. The present study provides an analysis of education professionals’ experiences and understandings of self harm in primary school children. Interviews with 15 staff members from six schools in the North of England were analysed using Interpretive Phenomenological Analysis. Key themes discussed concern: how self harm affects staff emotionally; reasons staff ascribe to children’s self harming; how self harm is managed. The present study indicates problems associated with a ‘fire‐fighting’ approach where self harm is only dealt with as it becomes visible. Instead, the authors advocate policy‐level initiatives proactively addressing self harm, as has happened in sex and drug education. Intervention around self harm in schools could usefully broaden staff members’ understandings of self harm, allow opportunity for reflection and discussion, and make resources available to staff working with children who self harm.  相似文献   

Correlates of Geriatric Loneliness in Philippine Nursing Homes: A Multiple Regression Model     

Allan B. de Guzman  Katrina N. Maravilla  Veniza Anne M. Maravilla  Jomille D.V. Marfil  Janine Angelica R. Mariñas  Jorelle Michael B. Marquez 《Educational gerontology》2013,39(8):563-575

Numerous studies have been conducted worldwide about loneliness in older adults living in nursing homes and the factors associated with it. However, only a few studies have focused on social factors that may predispose these older adults to experience loneliness. The purpose of this study was to examine the interplay between and among loneliness, social isolation, social engagement, and life satisfaction among Filipino elderly (n = 180) recruited from government and nongovernment nursing homes in the Philippines. A multiaspect questionnaire, which included the UCLA Loneliness Scale, Revised Index for Social Engagement, Friendship Scale, and Life Satisfaction for the Third Age-Short Form was used to gather the needed data and information. Results of single and multiple regression analyses indicate an effect of the three factors (social isolation, social engagement, and life satisfaction) on loneliness with social isolation having the greatest impact on loneliness. Notably, increased social isolation, inadequate social engagement and decreased life satisfaction consequently aggravate loneliness. Social engagement produced a positive effect to both social isolation and life satisfaction in a way that a decrease in social engagement will decrease life satisfaction and increase social isolation. On the whole, loneliness in geriatric nursing homes is evident, and it is shaped by social isolation, social engagement and life satisfaction. Impliedly, interventions and measures to minimize loneliness are necessary, and further research is needed to explore other variables contributing to loneliness in geriatric nursing homes.  相似文献   

Children's Ideas about Aging before and after an Intergenerational Read-aloud     

Katrina W. Hall  Jacqueline J. Batey 《Educational gerontology》2013,39(10):862-870

This study describes a pilot project that included senior volunteer readers reading aloud to third graders in diverse schools across a district in northeast Florida. The researchers interviewed students about their perceptions of the aging process before and after the read aloud as well as their view of the read aloud events. The children enjoyed being read to by the senior volunteers, who were able to support the children's understanding of a fairly complex book. Further, the senior volunteers, who had expressed some hesitancy about reading to older children, greatly enjoyed the interaction. The study supports the idea that children's ideas about aging may be impacted both by book selection and the reader, and it posits that reading aloud to older children by senior volunteers may be beneficial to all parties involved.  相似文献
