The effect of sodium pentobarbital on attraction in the albino rat     

Lee A. Becker  Dennis C. Wright  David Kelley  Steve Harkins  Laura Majcher  Bruce Lammers 《Learning & behavior》1973,1(1):77-80

Two “target” rats, one drugged and one undrugged, were tethered on opposite sides of an open arena in which single, undrugged “subject” rats were allowed to roam free. On the last 2 days of testing, the S rats spent significantly more time in physical contact with the undrugged target rat than with the drugged target rat. Prior adaptation to the arena of S rats had no effect on the relative preferences for the target animals.  相似文献

Employing phenomenological techniques this qualitative study investigates perceptions of collaborative relationships between instructional designers and faculty at an R1 university. While past research has considered the growing involvement of instructional designers in course development, and knowledge and skills expected from an instructional designer, little attention has been paid to what constitutes an effective collaboration and how it can be developed from the perspectives of both instructional designers and faculty. Based on semi-structured interviews of faculty and instructional designers, the following four thematic categories were uncovered: (1) reasons for collaborative efforts; (2) structure of collaborative relationships; (3) supports of and barriers to collaboration; and (4) essential competencies and strategies for instructional designers and faculty in a collaborative partnership. Our findings support the existing research on the importance of collaboration between instructional designers and faculty, and spotlights instructional designers in the higher education setting. They also outline key elements of an effective relationship, including understanding the role of an instructional designer, trust and rapport building (and its components), administrative support and faculty buy-in. Suggestions are made for to how overcome potential barriers to ensure an effective and collaborative partnership. Implications and future directions for research and training programs are discussed.

The relationship between working memory and writing in younger and older adults     

Hoskyn  Maureen  Swanson  H. Lee 《Reading and writing》2003,16(8):759-784

This study investigated therelationship between working-memory (WM) spanand writing performance in three age groups(mean of ages of 15, 30, 77 years). Asexpected, older adults' performance wasinferior to younger adults on measures ofverbal and visual-spatial WM and structuralcomplexity in writing. More important, WM spanmoderated structural complexity in writingacross age and those effects remainedsignificant when short-term memory, readingcomprehension, word knowledge, spelling andhandwriting speed were partialed from theanalysis. Overall, the results support thenotion that age-related changes in textgeneration are moderated by limitations in ageneral WM system.  相似文献   

Problems in Teaching the Topic of Redox Reactions: Actions and Conceptions of Chemistry Teachers     

Onno De Jong  Jeannine Acampo  Adri Verdonk 《科学教学研究杂志》1995,32(10):1097-1110

Although there is growing interest in studies of teachers' actions and conceptions, little is known about content-related teaching problems arising in science classrooms. This article presents a case study of problems which can occur when teaching the topic of redox reactions to Grade 11 students. Two chemistry teachers, a senior and a junior teacher, were involved in the study. Their reflective comments on the teaching problems were also investigated. Research data were obtained from classroom observations and audiotaped recordings of classroom practice. After the lessons, we conducted semistructured interviews with the teachers. The teaching problems are reported in terms of teaching activities causing difficulties for students in considering new conceptions to be necessary, intelligible, plausible, or fruitful. Analyses of the teachers' comments on these teaching activities clarifies a number of reasons why they acted as they did. It can be concluded that teachers' scientific expertise is an important source of difficulties when teaching redox reactions. Implications for an improvement of current chemistry classroom practice and content-related teacher training are offered.  相似文献

The influence of prior knowledge on experiment design guidance in a science inquiry context     

Siswa A. N. van Riesen  Hannie Gijlers  Anjo Anjewierden  Ton de Jong 《International Journal of Science Education》2018,40(11):1327-1344

Designing and conducting sound and informative experiments is an important aspect of inquiry learning. Students, however, often design experiments that do not allow them to reach conclusions. Considering the difficulties students experience with the process of designing experiments, additional guidance in the form of an Experiment Design Tool (EDT) was developed, together with reflection questions. In this study, 147 pre-university students worked in an online inquiry learning environment on buoyancy and Archimedes’ principle. Students were randomly assigned to one of three conditions, each of which contained a different version of the EDT. Since students’ prior knowledge has been found to influence the amount and type of guidance they need, the versions of the tool differed with respect to the level of guidance provided. A pre- and post-test were administered to assess students’ conceptual knowledge. No overall differences between conditions were found. In a subsequent analysis, students were classified as either low, low-intermediate-, high-intermediate, or high prior knowledge students. For Archimedes’ principle we found that low-intermediate prior knowledge students gained significantly more conceptual knowledge than low prior knowledge students in the fully guided condition. It is hypothesised that students need at least some prior knowledge in order to fully benefit from the guidance offered.  相似文献   

Additive effects due to biochar and endophyte application enable soybean to enhance nutrient uptake and modulate nutritional parameters     

Muhammad Waqas  Yoon-Ha Kim  Abdul Latif Khan  Raheem Shahzad  Sajjad Asaf  Muhammad Hamayun  Sang-Mo Kang  Muhammad Aaqil Khan  In-Jung Lee 《Journal of Zhejiang University. Science. B》2017,18(2):109-124

We studied the effects of hardwood-derived biochar (BC) and the phytohormone-producing endophyte Galactomyces geotrichum WLL1 in soybean (Glycine max (L.) Merr.) with respect to basic, macro- and micronutrient uptakes and assimilations, and their subsequent effects on the regulation of functional amino acids, isoflavones, fatty acid composition, total sugar contents, total phenolic contents, and 1,1-diphenyl-2-picrylhydrazyl (DPPH)-scavenging activity. The assimilation of basic nutrients such as nitrogen was up-regulated, leaving carbon, oxygen, and hydrogen unaffected in BC+G. geotrichum-treated soybean plants. In comparison, the uptakes of macro- and micronutrients fluctuated in the individual or co-application of BC and G. geotrichum in soybean plant organs and rhizospheric substrate. Moreover, the same attribute was recorded for the regulation of functional amino acids, isoflavones, fatty acid composition, total sugar contents, total phenolic contents, and DPPH-scavenging activity. Collectively, these results showed that BC+G. geotrichum-treated soybean yielded better results than did the plants treated with individual applications. It was concluded that BC is an additional nutriment source and that the G. geotrichum acts as a plant biostimulating source and the effects of both are additive towards plant growth promotion. Strategies involving the incorporation of BC and endophytic symbiosis may help achieve eco-friendly agricultural production, thus reducing the excessive use of chemical agents.  相似文献   

Teaching Kindergartners Racial Diversity Through Multicultural Literature: A Case Study in a Kindergarten Classroom in Korea     

So Jung Kim  Young Mi Lee 《Early education and development》2016,27(3):402-420

Research Findings: This qualitative case study examines Korean kindergartners’ literary discussions about racial/cultural diversity during a whole-group read-aloud. Using multiple sources of data, including observations, open-ended interviews, and written materials and children’s artifacts, this study found that (a) the children exhibited a biased attitude toward African characters, and their stereotypical views reflected their allegiance to their social/cultural contexts; (b) literary discussions about race provided the children with valuable opportunities to explore racial diversity, equality, injustice, and freedom; and (c) reading multicultural literature helped the children develop and practice their racial language and literacy skills. Practice or Policy: The findings of the study add several important contributions related to teaching young children multicultural literature. Reading literature should be used to provide a chance to explore real-life problems and critically analyze all of the differences children encounter on a daily basis. Teachers should encourage young children to freely share their views about diverse social issues by creating a space where children feel secure in exchanging different views. In order to create a more supportive literacy surrounding, teachers should understand how profoundly children’s social and cultural environments affect their reading practices.  相似文献
