This study describes a tutoring program designed to help children in grades 3 through 5 who underwent an unscheduled school transfer. We examined gender differences in self-concepts, academic performance, teacher evaluations, and peer ratings. Gender differences were found in several measures, although gender did not substantially interact with the intervention. As expected, female transfer students reported lower self-concepts than males; teachers reported that boys were more popular; peers also rated boys as more aggressive and girls as more likable. Findings suggest that preventive interventions for transfer students need to account for effects of gender.  相似文献

Project SEARCH (Science Education and Research for CHildren) is an outreach program designed to teach science and to foster positive attitudes toward science. Through the project, university science students bring activity-based learning, plus materials and content expertise, to local classrooms and after-school programs. Using observations, surveys, and interviews, we examined the experiences of these students as curriculum planners, teachers, and role models for the children. We found that teachers value the enthusiasm and the resources provided by the SEARCH students. Children were engaged in the activities and looked forward to the students' visits. They also see them as positive and diverse models for the role of scientist. But there were often problems in the areas of preparation, scheduling, and communication, and the classroom activities often replicated traditional didactic lessons. The SEARCH experience highlights both the value of providing diverse and challenging experiences for children, and the need for dialogue and reflection on those experiences. Despite several concerns, the SEARCH model is one that deserves expansion and further study as it is extended into new settings. © 1997 John Wiley & Sons, Inc.

Epistemological beliefs, or beliefs about the nature of knowledge and knowing, are currently a target of increased research interest. The present study examined two research questions: (1) how do epistemological beliefs change over time? and (2) what role do gender, ethnicity, SES, and achievement play in their development? The study was correlational with an ethnically diverse sample of 187 fifth grade students (46% Latino, 27% Anglo, and 27% African American, and 67% low SES). Self-report questionnaires that tapped four dimensions of beliefs (source, certainty, development, and justification) were given to students at two time points during the course of a nine-week science unit. Results showed that students became more sophisticated in their beliefs about source and certainty of knowledge over time, but that there were no reliable changes in development and justification. There also were no main or moderating effects of gender or ethnicity, but there were main effects of SES and achievement. Low SES and low achieving children had less sophisticated beliefs in comparison to average SES and high achieving children. There were no significant interactions between gender, ethnicity, SES, and achievement for any of the four belief measures. Results are discussed in terms of personal and contextual factors and their role in the facilitation of epistemological belief development.  相似文献

An analogy is a model drawn from one contextand used to support understanding in anothercontext. This study investigates the extent towhich analogies in instructional science booksare provided by authors. The books surveyed areavailable from commercial suppliers andintended for use in the elementary schoolclassroom with 7 to 11 year old children.Eighty texts were analysed for the presence orabsence of analogies. Forty-five of the booksoffered no analogies at all. In the remainingthirty-five books, 92 analogies were found.These were classified in line with earlier workon analogies for older students by Curtis andReigeluth (1984) and the findings arediscussed. The extent to which teachers candraw upon the analogies in such texts tosupport children's understanding isconsidered.  相似文献

The purpose of this study was to determine the quantitative and qualitative portrayal of females and minorities in the illustrations of seven contemporary elementary science textbook series. An evaluation instrument was devised to determine the current status of the targeted groups. Illustrations were evaluated on the basis of minority/nonminority and male/female repesentation. The activity and assumed role of the individuals were also tabulated. More than 5900 human illustrations were evaluated. The results reveal that female children as a group are represented with greater frequency than are other child groups. Minority children are represented less often than nonminority children and female and minority adults are depicted less often than nonminority male adults. The textbooks evaluated in this study display science positively for most societal groups. However, minorities are underrepresented and illustrated in a limited number of career roles. Implications and suggestions for teachers, supervisors, and teacher educators are provided.  相似文献

The need for students to learn science, technology, engineering, and mathematics (STEM) has increased steadily, while student motivation in this area continues to fall behind. We investigated the effects of science utility value intervention in increasing the science motivation (i.e., interest in science, appreciation of the role of science in future careers, and intention to engage in science-related activities) of Korean 5th and 6th graders. The usefulness of science for attaining the personal and communal goals inherent to various non-STEM careers was emphasized and internalized through classroom activities including postcard writing. At the end of the semester, students in the experimental group (n = 219) perceived greater personal and communal utility in science than those from the control group (n = 197). This enhanced perception of science utility led to greater interest, a higher likelihood of cognitively connecting science to future careers, and the willingness to engage in scientific activities.  相似文献

Abstract: This article reports on a study that investigated the ways that children's use of science journals aided their acquisition of science understandings in one kindergarten and one fourth‐grade classroom. The questions for investigation were: how does the child contextualize the science experience on the journal page? How do child‐produced graphics on the journal page reflect the children's experiences with other school texts? The study found that children recontextualized their understandings of the science investigation and phenomena by using three types of mental contexts that were reflected in their science journals: these contexts were imaginary, experienced, and investigative worlds. By drawing on these three worlds or internal contexts, the children were able to pull the external phenomenon into an internal context that was familiar to them. The child's construction of ideas about a current science experience as expressed on the journal page may reflect experiences with other conventional texts. In this study the children's representations of their imaginary, experienced and/or investigative worlds were shaped by other texts and structures such as school science texts. © 2000 John Wiley & Sons, Inc.

Background: There is a growing interest in investigating attitudes towards science and views of Nature of Science among elementary grade students in terms of gender, cultural backgrounds, and grade level variables.

Purpose: The purpose of this study is to examine the attitudes toward science and views of Nature of Science among Spanish students, Spanish students of gypsy ethnicity and second-generation Spanish students with east-European heritage, and to determine if their attitudes are related to their views of Nature of Science.

Sample: Data for this study was gathered from seven elementary schools in Spain, forming a convenience sample of 149 students enrolled from 2nd to 5th grade.

Design and Methods: The Nature of Science Instrument (NOSI) and an adaptation of the Test of Science Related Attitudes scale (TOSRA) were used. Follow-up structured interviews were performed with 15 participants.

Results: Regarding gender, boys had better attitudes toward Science than girls but more naïve views of the empirical Nature of Science. In relation to cultural background, second generation Spanish students with east-European heritage reported significantly better attitudes toward Science than Spanish students and Spanish students of gypsy ethnicity. No differences in Nature of Science views were found. Concerning grade level, third graders had more positive attitudes toward Science than fifth and sixth graders and more informed views of the tentative Nature of Science. Finally, no relation between Nature of Science views and attitudes towards Science were identified.

Conclusion: This study stress the need to address the steady decline in positive attitude toward Science and to improve students’ views of Nature of Science from early elementary grades, and to use gender and culturally inclusive science teaching strategies.  相似文献

The study investigated the ability of primary and elementary school subjects to generalize two science concepts, Insect and Animal with and without instruction in the form of a mental set. It also examined the effects of age, IQ, and sex on the ability of the children to generalize these concepts. Two instruments measuring the ability to generalize the concepts Insect and Animal were developed. The results indicate that of the independent variables investigated, age and mental set significantly affected the ability to generalize the concepts Insect and Animal. It was found that the younger children's concepts were least developed and with age these concepts became more developed and more conceptual in nature. The ability to use information given in a mental set was found to be a function of age. The children in this study were more able to generalize the concept Insect than the concept Animal. The results suggest that children with age and instruction axe better able to master less general concepts than more geaeral ones. In addition, the study demonstrated that children are able to improve their learning of general concepts provided a great number and variety of instances and noninstances of the concept are used in the instruction. It was also found that the younger children were more perceptually bound than the older children. The younger children were unable to overcome the pull of perceptual attractiveness that the noninstances held for them despite instruction. The results suggest that teachers of such children should be aware of the conceptual level of the content being taught to such children to ensure appropriate and meaningful learning takes place.  相似文献

This study examined the impact of an inquiry‐based instructional intervention on (a) children's ability to conduct science inquiry overall and to use specific skills in inquiry, and (b) narrowing the gaps in children's ability among demographic subgroups of students. The intervention consisted of instructional units, teacher workshops, and classroom practices. The study involved 25 third‐ and fourth‐grade students from six elementary schools representing diverse linguistic and cultural groups. Quantitative results demonstrated that the intervention enhanced the inquiry ability of all students regardless of grade, achievement, gender, ethnicity, socioeconomic status (SES), home language, and English proficiency. Particularly, low‐achieving, low‐SES, and English for Speakers of Other Languages (ESOL) exited students made impressive gains. The study adds to the existing literature on designing learning environments that foster science inquiry of all elementary students. © 2005 Wiley Periodicals, Inc.
