Students' explanations of biological phenomena are frequently characterized by disconnects between levels and confusion of levels. The purpose of this research is to investigate the effects of a hands-on lab activity that aims at fostering the ability to reason across levels. A total of 197 students (18 years of age) participated in a randomized, pre–post-test design study. Students in the experimental group engaged in a lab activity focused on artificial selection and designed to demonstrate how selection affects both phenotypes and genotypes. In contrast, the lab activity in the comparison group focused on phenotype alone. Data sources for the study included pre-tests of basic concepts in genetics and evolution and two post-test items requiring the students to reproduce and apply their knowledge about artificial selection. The findings indicated that the lab activity which allowed students to explore the interplay between different levels, provided vertical coherence and enhanced students’ ability to explain evolutionary change in both reproduction and transfer items. In contrast, the lab activity in the comparison group failed to do so, and most students did not improve their ability to explain evolutionary change. Implications for instruction and recommendations for further research are discussed in light of these findings. 相似文献

This study examined individual differences among beginning readers of English as a foreign language (EFL). The study concentrated
on the effects of underlying first language (L1) knowledge as well as EFL letter and vocabulary knowledge. Phonological and
morphological awareness, spelling, vocabulary knowledge, and word reading in Hebrew L1, in addition to knowledge of EFL letters
and EFL vocabulary, were measured. The study also investigated the effect of socioeconomic background (SES) on beginning EFL
readers. Participants included 145 fourth graders from three schools representing two socioeconomic backgrounds in the north
of Israel. The results indicate that knowledge of English letters played a more prominent role than knowledge of Hebrew L1
components in differentiating between strong and weak EFL readers. The Linguistic Coding Differences Hypothesis was supported
by L1 phonological awareness, word reading, and vocabulary knowledge appearing as part of discriminating functions. The presence
of English vocabulary knowledge as part of the discriminant functions provides support for English word reading being more
than just a decoding task for EFL beginner readers. Socioeconomic status differentiated the groups for EFL word recognition
but not for EFL reading comprehension. 相似文献

AbstractIt is a well-documented finding that students tend to neglect their real-world knowledge when solving word problems, even when realistic assumptions are needed. Although studies have successfully shown the extent to which students tend to provide unrealistic responses, the question of where this tendency comes from has yet to be answered. We focused on two major steps needed to solve realistic word problems: noticing missing information and making realistic assumptions. We conducted two studies with fifth graders (Study 1, N?=?108; Study 2, N?=?60) in which we compared students’ (un-)realistic responses to problems that differed in how obvious the missing information was. Study 1 fostered only students’ ability to make assumptions. Study 2 fostered this ability plus the ability to notice missing information. The results indicate that, if the missing information is not obvious, students’ failure to notice it seems to be what prevents them from arriving at a realistic solution. 相似文献

The subject of the study comprised individual differences of creative achievements among 6‐year‐old children in two basic and qualitatively different kinds of child's activity: verbal and artistic. The aim of the research was both the analysis of the creative capacity level differentiation and pointing out the hierarchy of factors which determine certain inter‐ and intra‐individual as well as inter‐ and intro‐group differences.
The study is based on the concepts of the creativity theory of Wallach and Kogan (1970) and the capacity theory of Renzulli (1986) and Monks (1981) developed within the framework of humanistic and cognitive psychology.
The researcher analysed 6,000 drawings and the same number of oral statements produced by 643 children attending two types of pre‐schools and living in three different habitats. The research also covered teachers working with the 6‐year‐old children.
The following were used in the study: the test ‘Draw‐a‐Man’ of Goodenough; Guilford's tests of divergent thinking; Uszynska's Questionnaire of self‐estimation; The Schaefer's and Aaronson's Classroom Behaviour Inventory Pre‐school to Primary Scale; Popek's Questionnaire of Creative Behaviour ‘KANH’, and Uszynska's Questionnaire for parents.
The results of the research confirm a great differentiation of creative capacity levels of children and suggest that the most significant factors determining them are the pedagogic ones, which may directly or indirectly be influenced by the preschool teacher. 相似文献

This article examines the content and methodology of studies on Tai Chi as a sport in health care. We investigate the concept behind the rather simple name “Tai Chi,” concluding that this concept is manifold and highly variable. How did researchers deal with this variability when studying the effects of Tai Chi as a health-care intervention? We then explore how scientific research on Tai Chi has been conducted to date and draw the interim conclusion that the variability was barely taken into consideration. Our analysis of seven Tai Chi interventions reveals that two interventions referred to as Tai Chi may differ considerably in their content. The variability poses difficulty in repeating the intervention and drawing causal inferences. This problem is discussed in the current literature under the term “complexity in health-care interventions.” On the basis of a summary of this debate, we discuss the challenge of researching Tai Chi from a complex perspective—with the aim of achieving solid results that can be repeated. 相似文献

Recent changes in the system of early childhood teacher education in Germany raise the question of whether different academic levels of early childhood teacher education lead to different beliefs and orientations. In this study, prospective early childhood teachers' orientations to scientific knowledge and to research were explored. A questionnaire addressing orientations to the utility of research, educational and psychological theories versus orientations to intuitive theories and personal experience was completed by 712 prospective early childhood teachers. In a latent profile analysis, two types of orientation profiles could be identified: (a) an orientation towards subjective theories, lay theories, and subjective experience, and (b) an orientation towards scientific theories and research results. Results are discussed from the perspective of professionalization in early childhood teacher education. 相似文献

Abstract This paper discusses the problems caused by certain approaches to the measurement of educational product and the way in which these conflict with the longer term objectives of the educational process. It argues that, in many areas of higher education, especially those with vocational or professional links, these approaches to the measurement of student performance produce a tendency towards ‘short‐termism’ that is very similar to trends that have been identified in the management and accounting literature. The author argues that whilst accounting educators in the USA have identified a need to broaden the learning experiences of students, and to reduce the significance of surface learning, there are pressures in the, UK that would seem to be forcing students into increased surface learning and less reflective, deeper learning. 相似文献

Pre-service teachers tend to use their personal experiences as critical filters in accepting and integrating course content that is intended to develop professional decision-making frameworks. This may restrict their abilities to deal with pedagogical issues associated with the acceptance of diversity and individuality, and encourage an unthinking acceptance of the status quo in classrooms, schools and society. To address this problem and nurture the growth of 'reflective practitioners', we structured the content and experiences of one unit of the Graduate Diploma of Education (secondary) to allow for the integration of personal life histories with other views and perspectives. This paper reports on the use of this life-history approach, its potential and its limitations. 相似文献

The importance of quality in the provision of day care services for young children is well established. A project designed to address issues of assessing, maintaining and enhancing standards of service provision in the UK developed a set of self‐assessment materials for use in group day care settings. This paper describes a project to evaluate whether versions of the same materials might be effective in group day care settings in Hungary. Differences and similarities between service provision in the UK and Hungary are described. In a study involving 76 Hungarian day care centres, > 80% of staff involved thought using the materials raised their awareness of quality issues, although the materials did not have a significant impact on the quality of care provided. Key differences between service provision in the UK and Hungary are identified as influencing the potential effectiveness of the materials in assessing, maintaining and enhancing quality. 相似文献
