The cognitive processes used by children during problem solving have received considerable attention in recent years. The identification of the processes used by both successful and unsuccessful problem solvers has been hampered by the difficulties involved in making accurate observations of mental processes which may or may not have physical manifestations during problem solving. In addition, problem solvers themselves often are unaware of many of the thought processes they use while attempting to solve problems. The most popularly used methods for studying problem solving processes are not sufficiently reliable or valid. This study explored the potential effectiveness of a new procedure for identifying and studying certain of the cognitive processes used during problem solving. In addition, the procedure was used to categorize the types of conceptual thinking problem solvers employ, to study the use of trial and error behavior, and to investigate problem solvers’ abilities to coordinate multiple bits of information. It appears that the procedure has application for generating hypotheses about cognitive processes problem solvers use. 相似文献

The article looks at the practice of teaching in the light of the Part One of Martin Heidegger's major work Being and time. After discussing the main themes of this work, and particularly Heidegger's argument that our fundamental way of being is not cognitive, it examines their implications for such issues as the place of theory and reflection in education. The article then considers generalised approaches to professional work, notably those of Donald Schön and Andrew Abbott. It concludes that teaching has unique characteristics which are illuminated by Heidegger's writing. It suggests that teachers’ practice exhibits a tension between instrumentality and a concernful being-with children, but is fundamentally grounded in the latter. 相似文献

The Third Edition of the ACEI Global Guidelines Assessment (GGA) was evaluated for its effectiveness as an international assessment tool for use by early childhood educators to develop, assess, and improve program quality worldwide. This expanded study was conducted in nine countries [People’s Republic of China (2 sites), Guatemala, India, Italy, Mexico (2 sites), Peru (2 sites), Taiwan, Thailand, United States] to continue the investigation of the psychometric properties of the GGA. A total of 346 programs and 678 early care and education professionals participated in this study. Results primarily confirmed the findings of the previous study, (Hardin et al. in Early Child Educ J 41(2): 91–101, 2013), indicating that the GGA showed strong to moderate internal consistency and interrater reliability for subscale ratings across this larger number of countries and programs. The congruence of item ratings and written evidence to support ratings was acceptable, although some programs had lower participation in providing evidence. To test concurrent validity of ratings, external raters also evaluated a subset of programs (n = 44 from Peru and United States) on both the GGA and the Early Childhood Environment Rating Scale-Revised that showed moderate positive correlations. Patterns of program practices were also identified within and across the participating sites and countries. Results suggest that the GGA can be used as an onsite evaluation method that can help stakeholder participants (teachers and administrators) increase their awareness of program quality standards and serve as an assessment method for their own programs. In particular, the results suggest the GGA is a reliable and useful instrument that can be used effectively by early childhood stakeholders for assessing and improving program quality worldwide (Bergen and Hardin in Child Educ 91(4): 259–264, 2015). 相似文献

Groups of 11‐year‐olds in their first term at secondary school were given three cognitive tests. Girls and boys were found to be approximately equal in science knowledge. Boys did slightly better on tests of physical science, especially when these were in multiple choice form, but otherwise there were few sex differences. Neither the style of the question (multiple choice or structured) nor the content (feminine or masculine) had any great effect on sex differences in performance. However, boys performed markedly better than girls on tests of spatial ability and mechanical reasoning. These skills may be important for later success in technical studies at school. 相似文献

ABSTRACT: Commercial, nonthermal processing of food, such as high hydrostatic-pressure processing (HPP), has increased. The safety and quality of foods produced by HPP has not been well communicated to the public. An online, nationwide consumer survey was implemented to assess awareness of alternative food processing technologies, consumer food safety attitudes and knowledge, and willingness to pay (WTP) for HPP products. The consumer survey was administered by Zoomerang™, an online survey clearinghouse. The survey was completed by 1204 adults. Frequencies and crosstabs were calculated on Zoomerang and SPSS used for one-way ANOVA and chi-square analyses. The survey assessed knowledge of HPP, attitudes about new food processing techniques, WTP for HPP foods and demographics. Overall, many demographic characteristics reflected U.S. census population. While traditional methods, that is, canning, freezing, and microwaving were all well recognized by over 80% of respondents, only 8% recognized HPP. Trends indicated an increase in age, education, and income reflected greater food safety knowledge. Regardless of demographics, no survey respondent exhibited knowledge mastery (80%). Given an explanation of HPP and its benefits, 39% of respondents indicated they would be WTP an additional cost, with higher income and education having the most impact. Majority of respondents indicated a WTP of $0.25 to $0.50 regardless of the value of the food product. More respondents were WTP slightly more for a more expensive product. New technologies often encounter a stumbling block in consumer acceptance and processing costs. A consumer's WTP, once they were informed, could encourage industry to look favorably on this technology. 相似文献

This paper points out that globalization has raised fundamental questions about knowing and learning and that it is essential for educators to engage in collective knowledge generation by crossing community boundaries. Drawing on the theoretical framework of Activity Theory, this paper reports on a study on the expansive learning that was afforded by a school–university partnership as university tutors, mentor teachers and student teachers engaged in a new activity system mediated by lesson study. The study showed that in the course of resolving contradictions that were inherent in the boundary zone, they negotiated the mediating tool and consequently, the activity system was transformed from helping student teachers learn to teach into learning for all participants. This paper concludes that it is essential for teachers and teacher educators to develop the capability to engage in expansive learning through tackling ill-defined problems in boundary zones. 相似文献

The purposes of this study were to (a) examine the developmental patterns in pseudoword reading and oral reading fluency in Spanish and English for Spanish-speaking English learners (ELs) in grades 1?C3, and (b) investigate whether initial status and growth rates in reading fluency in Spanish and English, significantly predicted reading comprehension within languages and across languages. Participants were 173 Spanish-speaking ELs in first grade, 156 ELs in second grade, and 142 ELs in third grade across four schools providing a paired bilingual reading program. Results of hierarchical linear modeling indicated different patterns of reading growth in Spanish and English across measures and across grades. ELs at the beginning of first grade had higher scores on pseudoword reading in Spanish than in English and had a higher rate of growth on Spanish pseudoword reading. In second and third grades, initial scores on oral reading fluency were comparable in both languages, but oral reading fluency growth rates were higher in English than in Spanish. Results from regression and path analysis indicated that student initial scores and growth on reading fluency were strong and direct predictors of their reading comprehension within the same language, but not across different languages. 相似文献

The purpose of this study was to investigate the effect of orienting activities and type of practice on achievement, continuing motivation, and student behaviors in a cooperative learning environment. Eighty graduate education majors were assigned to cooperative groups and required to learn instructional design principles from three instructional television lessons. Each lesson included specific orienting activities (advance organizers or objectives) and different types of practice (verbal information or intellectual skills). Results indicated that subjects who worked in groups that received intellectual skills practice performed better on the application portion of the posttest than those who received verbal information practice. Knowledge acquisition and student behaviors were affected by a combination of type of practice and orienting activity. Groups that received intellectual skills practice discussed more content, gave more help to their fellow group members, and exhibited less individual behavior than groups that received verbal information practice. Groups given objectives discussed significantly more content than groups given advance organizers. The authors wish to thank Steven Ross and the reviewers ofETR&D for their helpful comments on an earlier draft of this paper. 相似文献
