Elementary teachers' epistemological and ontological understanding of teaching for conceptual learning     

Nam‐Hwa Kang 《科学教学研究杂志》2007,44(9):1292-1317

The purpose of this study was to examine the ways in which elementary teachers applied their understanding of conceptual learning and teaching to their instructional practices as they became knowledgeable about conceptual change pedagogy. Teachers' various ways to interpret and utilize students' prior ideas were analyzed in both epistemological and ontological dimensions of learning. A total of 14 in‐service elementary teachers conducted an 8‐week‐long inquiry into students' conceptual learning as a professional development course project. Major data sources included the teachers' reports on their students' prior ideas, lesson plans with justifications, student performance artifacts, video‐recorded teaching episodes, and final reports on their analyses of student learning. The findings demonstrated three epistemologically distinct ways the teachers interpreted and utilized students' prior ideas. These supported Kinchin's epistemological categories of perspectives on teaching including positivist, misconceptions, and systems views. On the basis of Chi's and Thagard's theories of conceptual change, the teachers' ontological understanding of conceptual learning was differentiated in two ways. Some teachers taught a unit to change the ontological nature of student ideas, whereas the others taught a unit within the same ontological categories of student ideas. The findings about teachers' various ways of utilizing students' prior ideas in their instructional practices suggested a number of topics to be addressed in science teacher education such as methods of utilizing students' cognitive resources, strategies for purposeful use of counter‐evidence, and understanding of ontological demands of learning. Future research questions were suggested. © 2007 Wiley Periodicals, Inc. J Res Sci Teach 44: 1292–1317, 2007  相似文献   

Promoting understanding of chemical representations: Students' use of a visualization tool in the classroom     

Hsin‐Kai Wu  Joseph S. Krajcik  Elliot Soloway 《科学教学研究杂志》2001,38(7):821-842

Many students have difficulty learning symbolic and molecular representations of chemistry. This study investigated how students developed an understanding of chemical representations with the aid of a computer‐based visualizing tool, eChem, that allowed them to build molecular models and view multiple representations simultaneously. Multiple sources of data were collected with the participation of 71 eleventh graders at a small public high school over a 6‐week period. The results of pre‐ and posttests showed that students' understanding of chemical representations improved substantially (p < .001, effect size = 2.68‐. The analysis of video recordings revealed that several features in eChem helped students construct models and translate representations. Students who were highly engaged in discussions while using eChem made referential linkages between visual and conceptual aspects of representations. This in turn may have deepened their understanding of chemical representations and concepts. The findings also suggest that computerized models can serve as a vehicle for students to generate mental images. Finally, students demonstrated their preferences of certain types of representations and did not use all types of three‐dimensional models interchangeably. © 2001 John Wiley & Sons, Inc.

Self‐Injury,Gender, and Loneliness Among College Students     

Lorrie Ann Dellinger‐Ness  Leonard Handler 《Journal of College Counseling》2007,10(2):142-152

Several studies have demonstrated relationships between loneliness and numerous psychological and physical difficulties among college students. The purpose of this study was to examine whether loneliness might be a factor associated with increased risk of self‐injury among college students. The findings did not support the hypothesis that self‐injury would be associated with elevated levels of loneliness. The findings were significant but in the opposite direction than expected. Furthermore, the findings regarding gender are in contrast to findings of previous research.  相似文献   

A Six‐Year Longitudinal Study of Texting Trajectories During Adolescence          下载免费PDF全文

Sarah M. Coyne  Laura M. Padilla‐Walker  Hailey G. Holmgren 《Child development》2018,89(1):58-65

This study examined growth trajectories of texting (and other media) over a 6‐year time period. Participants were 425 adolescents from Washington, USA (age 13 at Time 1, age 18 at Time 6; 48% male, 68% European American). Analyses suggested a curvilinear pattern for texting and social media use, with rates peaking during midadolescence. There was also considerable heterogeneity in trajectories of texting. A growth mixture model revealed four distinct classes of individuals: perpetuals (14%), decreasers (7%), moderates (68%), and increasers (11%). Higher levels of depression, being a male, and coming from a single‐parent family predicted being a “perpetual” texter. Perpetuals had the most problematic outcomes compared to other classes, including higher depression, anxiety, aggression, and poor relationships with fathers.  相似文献   

Does Student–Teacher Thinking Style Match/Mismatch Matter in Students’ Achievement?     

Li‐fang Zhang 《教育心理学》2006,26(3):395-409

This study concerns the contingent nature of the relationships of student–teacher style match (or mismatch) to students’ academic achievement. Participants were 135 (59 male and 76 female) students (average age of 21.5 years) from three academic disciplines (mathematics, physics, and public administration) who responded to the Thinking Styles Inventory and rated their own abilities (analytical, creative, and practical). The academic achievement scores in two subject matters for each student were also used. The students’ subject matter teachers responded to the Thinking Styles in Teaching Inventory. Three major findings were obtained. First, the effects of style match/mismatch upon students’ achievement vary as a function of academic discipline and subject matter. Second, the statistical procedures used to analyse the data play an important role in the relationships under investigation. Third, students’ self‐rated abilities make a difference in the tested relationships. Findings have implications for both researchers and teachers.  相似文献

Foucault, narrative and the subjugated subject: Doing research with a grid of sensibility     

Valerie Harwood 《The Australian Educational Researcher》2001,28(3):141-166

This paper introduces the grid of sensibility, a strategy that engages Foucaultian analysis and narrative research to provide a theoretical basis for research on subjugated knowledge. This strategy was devised in response to the specific needs of a study that sought to consider the experiences of subjugated and disqualified young people who had been told they were mentally disordered. The grid of sensibility functioned as a communicative meta-tool that provided a flexible, responsive and connected way to access the ideas and considerations that informed the research process. The grid of sensibility is discussed with reference to this study. The paper outlines the grid of sensibility, how it was applied, and suggests its potential application in other studies seeking to consider the perspectives of subjugated disqualified knowledges.  相似文献

Natoya H. Haskins  Jolie Ziomek‐Daigle  Cheryl Sewell  Lonika Crumb  Brandee Appling  Heather Trepal 《Counselor Education & Supervision》2016,55(1):60-75

Using phenomenological inquiry, this study explored the lived experiences and intersecting identities of 8 African American counselor educators who are mothers. Six themes were identified: race, professional strain, work–life balance, support, internalized success, and mothering pedagogy.  相似文献
