A specially designed questionnaire and a modification of the “Science Classroom Activity Checklist” by L. H. Krockendorfer were used to categorize 299 life science students at the University of Iowa into two groups; those with high school biology backgrounds founded in the BSCS philosophy and those with traditionally oriented backgrounds. These groups were compared with respect to grade achievement in a college life science course, ratings of their background for the college course, and their attitude toward biology as established by their high school experience. With respect to inquiry and student-centered methods, texts were revealed as poor indicators of types of programs offered.  相似文献

To assess the developmental relationship of perceptions of self-concept and gender role identification with adolescents' attitudes and achievement in science, a two-year longitudinal study was conducted. A battery of instruments assessing 16 dimensions of self-concept/gender role identifications was employed to predict students' achievement and attitudes toward science. Specific behaviors studied included self-concept in school and science and mathematics, attitudes toward appropriate gender roles in science activities and careers, and self-perceptions of masculine and feminine traits. One hundred and fifty-five adolescents, enrolled, respectively, in the seventh and eighth grades, participated in the study. Through Fisher z transformations of correlation coefficients, differences in relationships between these two sets of variables were studied for males and females during the two years. Results indicated that students' self-concepts/gender role perceptions were related to both achievement and attitudes toward science, but more related to attitudes than achievement. These relationships became more pronounced for students as they matured from seventh to eighth graders.  相似文献

Grade 10 students' perceptions of classroom practices and activities, as well as their attitudes toward science teaching and school science, were assessed in the Westend School District (pseudonym) in British Columbia, using both quantitative (statistics of Likert-type scales) and qualitative (critical interpretive analysis of interview data) methods. The major findings of the study were that students do not appreciate the most prevailing contemporary practices in science classes, perceived by them as mainly the copying of the teacher's notes, and that they prefer science teaching and learning in which they take an active and responsible part. Additionally, teaching style appears to be the major determinant of high school students' attitudes toward science and science teaching. No change in students' perceptions of and attitudes toward science teaching and school science (in 1989 compared with 1986) could be detected in spite of the impact made by the recently advocated constructivist and science-technology-society (STS) approaches on science curriculum and science education. It is argued, therefore, that more emphasis must be placed on the science teachers' role and their teaching style if an educational change in the constructivist/STS direction is to be achieved.  相似文献

A two part study investigated any relationship between student achievement and textbook content as well as any impact of a national project's recommendations on textbook content. First, analyses of student responses to biological items on the 1977 National Assessment of Educational Progress's survey of science showed a direct, linear relationship between achievement level and concept emphasis in biology textbooks. Second, a comparison between biology textbooks, published a decade apart, indicated significant changes in the degree of emphasis placed on 10 commonly accepted conceptual areas. Closer examination revealed that change in the amount of emphasis in one conceptual area, Growth and Development, was responsible for the significant difference found. Generally, the recommendations of the biology project were not reflected in the newer textbooks.  相似文献

The purpose of this study was to investigate the perceptual orientation and attitudes toward science of freshman community college students and the relationship of these characteristics toward science achievement. It was found that perceptual orientation (field independence-dependence) was related to attitudes toward science. In addition, it was found that students who were field independent and possessed a positive attitude toward science scored significantly higher on the science achievement test than students who were field dependent and possessed a negative attitude toward science.  相似文献

The proliferation of bioinformatics in modern biology marks a modern revolution in science that promises to influence science education at all levels. This study analyzed secondary school science standards of 49 U.S. states (Iowa has no science framework) and the District of Columbia for content related to bioinformatics. The bioinformatics content of each state's biology standards was analyzed and categorized into nine areas: Human Genome Project/genomics, forensics, evolution, classification, nucleotide variations, medicine, computer use, agriculture/food technology, and science technology and society/socioscientific issues. Findings indicated a generally low representation of bioinformatics-related content, which varied substantially across the different areas, with Human Genome Project/genomics and computer use being the lowest (8%), and evolution being the highest (64%) among states' science frameworks. This essay concludes with recommendations for reworking/rewording existing standards to facilitate the goal of promoting science literacy among secondary school students.  相似文献

This study was designed to determine the influence of resequencing general science content on sixth grade students' science achievement, attitudes toward science, and interest in science. Resequencing content was accomplished for experimental group students through revising the order of textbook chapters in a general science course, in order to clarify content structure and establish interrelationships among major concepts. The subjects were 203 sixth grade learners randomly assigned to the two treatment groups of resequenced content and nonresequenced content. The findings revealed that students for whom content structure was clarified through resequencing general science chapters exhibited significantly higher science achievement, significantly more positive attitudes toward science, and significantly greater interest in science than students for whom general science content was not resequenced.  相似文献

A 2 × 2 factorial design was employed in a quasi-experiment to investigate the effects of guidelines in group or individual settings on the calibration accuracy and achievement of 82 high school biology students. Significant main effects indicated that calibration practice with guidelines and practice in group settings increased prediction and postdiction accuracy. A significant interaction showed that students who practiced calibration in groups using guidelines showed the greatest accuracy in their predictions and postdictions. Students in the guidelines condition and in the group setting condition had significantly higher achievement scores. The findings of this study suggest that the use of guidelines and group settings can promote calibration accuracy and achievement in high school biology courses.  相似文献

The objective of this experimental study is to investigate the relationships among science teacher characteristics and student outcomes. The selected characteristics of teachers are their understanding of science processes and their ability to control variables, and the outcomes of students are the achievement in science contents and processes. The results support the hypothesized relationships and show that the teacher ability to control variables is a more valuable characteristic than the understanding of science processes for student achievement. Conclusions are drawn about the implications for the education of science teachers.  相似文献

This study explored the effects of an integrated video media curriculum enhancement on students' achievement and attitudes in a first-year general high school chemistry course within a multiculturally diverse metropolitan school district. Through the use of a treatment-control experimental design, approximately 450 students in Grades 9–12 were sampled on measures of chemistry achievement and attitude over the period of 1 academic year. The results revealed significantly higher achievement scores on standardized measures of achievement as well as on microunit researcher-designed, criterion-referenced quizzes for the treatment students who experienced a general chemistry course enhanced with an integrated use of a structured chemistry video series. Correlation of student achievement with logical thinking ability revealed that students with high levels of logical thinking ability benefited most from the video-enhanced curriculum. Treatment students also scored significantly higher than control students on the chemistry attitude instrument. These results along with qualitative supportive evidence suggest that this integrated video media curriculum intervention can positively affect student chemistry achievement and attitude across ability levels and across a diverse multicultural population. Furthermore, the data suggest that educational science video media in general, and the World of Chemistry video series in particular, are instructional tools that can be used effectively to bring the often abstract, distant worlds of science into close focus and within the personal meaningful realm of each individual student. © 1997 John Wiley & Sons, Inc.

In 1983, the Richardson Independent School District conducted an internal audit to assess the status of science education. The audit was in anticipation of Texas Administrative Code Chapter 75 which requires an inquiry-oriented, process-approach to the teaching of science. In response to the data, and to national reports advocating a broadening of the science education curriculum to address the needs of all students, the district established a committee to implement and evaluate their new K-6 SCIENCE THROUGH DISCOVERY curriculum. The Science Curriculum Improvement Study (SCIIS) was adopted as the focal component of the overall curriculum with subsequent, planned innovations to occur in accordance with the Concerns-Based Adoption Model. The purpose of this study was to assess the attitudes toward science of students who had completed one year of SCIIS compared to students in non-SCIIS classes. In addition, the attitudes of teachers who received inservice education and who had instructed SCIIS were compared to non-SCIIS teachers. While SCIIS and non-SCIIS teachers possess similar perceptions of science, drastic attitudinal differences were observed between SCIIS and non-SCIIS students. The results indicate that the nature of the curriculum, in conjunction with the necessary implementation support including inservice education, greatly enhances students perceptions of science.  相似文献
