The purpose of this study is to investigate the effect of school type (private and public) and gender on sixth, seventh, eighth and tenth grade students’ attitudes toward the environment. A total of 1497 students (n?=?765 girls; n?=?715 boys; and n?=?17 gender not provided) attending public (n?=?603) and private schools (n?=?892) located in Ankara participated in the study. A 45‐item Likert‐type questionnaire consisting of four dimensions, namely, awareness of environmental problems, national environmental problems, solutions to the problems and awareness of individual responsibility, was used to measure students’ environmental attitudes. A two‐way multivariate analysis of variance (MANOVA) was conducted to determine the effect of school type and gender on four dimensions of the environmental attitude questionnaire. Results showed that school type and gender had a significant effect on the collective dependent variables. Univariate ANOVAs indicated that mean scores on each dimension of the questionnaire were significantly different for students in public and private schools. Moreover, there was statistically significant mean difference between boys and girls with respect to scores on each dimension of the questionnaire. It is concluded as a result of the study that, although there are differences between categories of individuals, there is a widespread support for conservation of the environment among young people living in Ankara/Turkey. 相似文献

Environmental attitudes depend on the relative importance that individuals attach to themselves, other people, or all living things. These distinct bases have been found to predict environmental concern, and may act as statistically significant determinants of pro-environmental behaviours. We claim that examining the complex nature of value orientations and concern levels among elementary school students as well as the interrelationships between these attributes could guide researchers and educators in Turkey. This study aimed (1) to explore Turkish elementary students’ ecocentric and anthropocentric attitudes, and environmental apathy; (2) to investigate their egoistic, altruistic and biospheric value orientations as well as their environmental concerns; (3) to examine relationships among environment-related attributes and (4) to determine the role of gender on these attributes. Participants seemed to be highly concerned and held favourable ecocentric attitudes. Furthermore, students with higher levels of anthropocentric attitudes tended to exhibit higher levels of environmental apathy, and those expressing biospheric concerns held lower levels of egoistic concerns. The findings suggest that girls were significantly more concerned about environmental problems and tended to value nature more for its own sake than boys. 相似文献

The present study examined the comparative effects of a prediction/discussion‐based learning cycle, conceptual change text (CCT), and traditional instructions on students' understanding of genetics concepts. A quasi‐experimental research design of the pre‐test–post‐test non‐equivalent control group was adopted. The three intact classes, taught by the same science teacher, were randomly assigned as prediction/discussion‐based learning cycle class (N = 30), CCT class (N = 25), and traditional class (N = 26). Participants completed the genetics concept test as pre‐test, post‐test, and delayed post‐test to examine the effects of instructional strategies on their genetics understanding and retention. While the dependent variable of this study was students' understanding of genetics, the independent variables were time (Time 1, Time 2, and Time 3) and mode of instruction. The mixed between‐within subjects analysis of variance revealed that students in both prediction/discussion‐based learning cycle and CCT groups understood the genetics concepts and retained their knowledge significantly better than students in the traditional instruction group. 相似文献

This study investigated students’ scientific epistemological beliefs in relation to socio-economic status (SES) and gender.
Data were obtained from 1,152 eight grade Turkish elementary school students using Scientific Epistemological Beliefs instrument.
Canonical correlation analysis indicated that students with a working mother and educated parents as well as greater number
of books at home together with a separate study room are more likely to have tentative views and less likely to have fixed
views about science compared to students with unemployed mother, uneducated parents, less books at home, and no separate study
room. Generally, results revealed while family SES correlated positively with tentative views, it was negatively associated
with fixed views, implying that students from high SES family were more likely to believe that knowledge is uncertain and
not handed down by authority compared to students from low SES family. This study, however, failed to indicate any relationship
between father work-status, buying daily newspaper and epistemological beliefs. In addition, Multivariate Analysis of Variance
indicated that boys more likely to have tentative beliefs compared to girls. 相似文献

In this study, the effect of conceptual-change-texts-oriented instruction to seventh-grade students' understanding of ecological concepts was investigated. Using information collected through interviews and related literature, the Ecology Concept Test was developed and administered to 58 elementary students in two classes of an elementary school before and after the treatment. The experimental group received conceptual-change-texts-oriented instruction and the control group received traditional instruction. Results of independent t test analysis revealed a statistically significant difference between the gain score means of the students in both groups with respect to ecological concepts in favor of experimental group after the treatment. 相似文献

This study investigated the effectiveness of combining conceptual change text and discussion web strategies on students' understanding
of photosynthesis and respiration in plants. Students' conceptual understanding of photosynthesis and respiration in plants
was measured using the two-tier diagnostic test developed by Haslam and Treagust (1987, Journal of Biological Education 21: 203--211). The test was administered as pretest and posttest to a total of 233 eighth-grade students in six intact classes
of the same school located in an urban area. The test of logical thinking was used to determine the reasoning ability of students.
The experimental group was a class of 116 students received discussion web and conceptual change text instruction. A class
of 117 students comprised the control group received a traditional instruction. After instruction, data were analyzed with
two-way analysis of covariance (ANCOVA) using the Test of Logical Thinking and pretest scores as covariate. The conceptual
change instruction, which explicitly dealt with students' misconceptions, produced significantly greater achievement in understanding
of photosynthesis and respiration in plant concepts. Analysis also revealed a significant difference between performance of
females and that of males in the favor of females, but the interaction of treatment with gender difference was not significant
for learning the concepts. 相似文献

This study investigated students' achievement regarding photosynthesis and respiration in plants in relation to reasoning ability, prior knowledge and gender. A total of 117 eighth‐grade students participated in the study. Test of logical thinking and the two‐tier multiple choice tests were administered to determine students' reasoning ability and achievement, respectively. An analysis of covariance (ANCOVA) was conducted to assess the effect of reasoning ability on students' achievement. The independent variable was the reasoning ability (low, medium, high), the dependent variable was the scores on the two‐tier test. Students' grades in science in previous year were used as a covariate. Analysis revealed a statistically significant mean difference between students at high and low formal levels with respect to achievement. Stepwise multiple regression analysis revealed that reasoning ability, prior knowledge and gender were significant predictors of students' achievement in photosynthesis and respiration in plants, explaining 42% of the variance. 相似文献

This study proposed a path model of relationships among understanding and acceptance of evolution, views on nature of science, and self-efficacy beliefs regarding teaching evolution. A total of 415 pre-service science teachers completed a series of self-report instruments for the specified purpose. After the estimation of scale scores using unidimensional IRT models, path analysis suggested that sophisticated views on NOS were associated with higher levels of both understanding and acceptance of evolution, and the higher level of understanding of evolution was related to the higher level of acceptance of evolution. Besides, higher levels of both understanding and acceptance of the theory and na?ve views on NOS were found to be associated with stronger self-efficacy beliefs for teaching evolution effectively. 相似文献

The authors conducted a correlational study to investigate the relations among seventh-grade Turkish students’ cheating behavior, academic self-efficacy beliefs, usage of self-handicapping strategies, personal goal orientations, and classroom goal structures specific to the science domain. The Patterns of Adaptive Learning Scales was administered to 1,950 seventh-grade students enrolled in 12 public schools. The authors conducted hierarchical linear modeling analyses to measure to what extent personal and contextual factors can be used to predict students’ cheating behavior. Analyses revealed that although students’ cheating behavior was positively predicted by performance-approach goals, it was negatively predicted by mastery goals. Students who used more self-handicapping strategies and who were less self-efficacious were also more likely to demonstrate cheating behavior. The authors found that the mastery goal–structured science-learning environment, in which understanding the material and self-improvement was emphasized, discouraged cheating. 相似文献
