Our main goal in this study was to determine whether the use of computer animation and illustration activities in high school can contribute to student achievement in molecular genetics. Three comparable groups of eleventh‐ and twelfth‐grade students participated: the control group (116 students) was taught in the traditional lecture format, whereas the experimental groups received instructions that integrated a computer animation (61 students) or illustration (71 students) activities. We used three research instruments: a multiple‐choice questionnaire; an open‐ended, written questionnaire; and personal interviews. Five of the multiple‐choice questions were also given to students before they received their genetics instruction (pretest). We found that students who participate in the experimental groups improved their knowledge in molecular genetics compared with the control group. However, the open‐ended questions revealed that the computer animation activity was significantly more effective than the illustration activity. On the basis of these findings, we conclude that it is advisable to use computer animations in molecular genetics, especially when teaching about dynamic processes; however, engaging students in illustration activities can still improve their achievement in comparison to traditional instruction. © 2007 Wiley Periodicals, Inc.

A theoretical model of nonscience majors' motivation to learn science was tested by surveying 369 students in a large‐enrollment college science course that satisfies a core curriculum requirement. Based on a social‐cognitive framework, motivation to learn science was conceptualized as having both cognitive and affective influences that foster science achievement. Structural equation modeling was used to examine the hypothesized relationships among the variables. The students' motivation, as measured by the Science Motivation Questionnaire (SMQ), had a strong direct influence on their achievement, as measured by their science grade point average. The students' motivation was influenced by their belief in the relevance of science to their careers. This belief was slightly stronger in women than men. Essays by the students and interviews with them provided insight into their motivation. The model suggests that instructors should strategically connect science concepts to the careers of nonscience majors through such means as case studies to increase motivation and achievement. © 2006 Wiley Periodicals, Inc.

The purpose of this study was to determine the best‐fitting structural equation model between the freshmen's physics achievement and selected affective characteristics related to physics. These characteristics are students' situational interest in physics, personal interest in physics, aspiring extra activities related to physics, importance of physics, importance of electricity, physics course anxiety, physics test anxiety, physics achievement motivation, student motivation in physics, self‐efficacy in physics, self‐concept in physics, and locus of control. The researchers developed the affective characteristics questionnaire that consisted of 12 subdimensions, and has 53 items related to these subdimensions. The questionnaire was applied to 890 freshmen physics students at the universities in Ankara. Two models were tested: a unidimensional model and a multidimensional model. However, a third model, which is more similar to the multidimensional model, exhibited the best fit for the freshmen. Moreover, the results revealed that achievement motivation was the most influential affective characteristic on physics achievement. On the other hand, motivation in physics had a negative influence on physics achievement in the model, and the influence of the students' attitudes towards physics was not statistically significant. Thus, one should especially pay attention to the students' achievement motivation in physics if the aim is to increase students' physics achievement. © 2007 Wiley Periodicals, Inc.

This 2-year quasi-experiment evaluated the effect of peer-led workshop groups on performance of minority and majority undergraduate biology students. The workshop intervention used was modeled after a program pioneered by Treisman (1992). Majority volunteers randomly assigned to workshops (n = 61) performed significantly better than those assigned to the control group (n = 60, p < 0.05) without spending more time studying. Workshop minority students (n = 25) showed a pattern of increasing exam performance in comparison to historic control minority students (n = 21), who showed a decreasing pattern (p < 0.05). Volunteers (n = 121) initially reported that biology was more interesting and more important to their futures than to nonvolunteers' (n = 435, p < 0.05). Volunteers also reported higher levels of anxiety related to class performance (p < 0.05). The relationship of anxiety to performance was moderated by volunteer status. Performance of volunteers was negatively associated with self-reported anxiety (r = –0.41, p < 0.01). Performance of nonvolunteers was unrelated to self-reported anxiety (r = –0.02). Results suggest elevated anxiety related to class performance may increase willingness to participate in activities such as workshop interventions. In addition, students who volunteer for interventions such as workshops may be at increased risk of performance decrements associated with anxiety. Even so, workshop programs appear to be an effective way to promote excellence among both majority and minority students who volunteer to participate, despite the increased risk of underperformance associated with higher levels of anxiety. 相似文献

AbstractA theoretical model of the relationship between class size and achievement is proposed, based on the assumption that a teacher adjusts the style and pace of a lesson to the least able student in the class. It is shown that the model and an extension to take into account the duration of instruction account well for various features of the data collected in the Glass and Smith (1978) meta-analysis of research. In particular, a correlation of 0.62 between predicted and empirical effect sizes was obtained. 相似文献

Active‐learning labs for two topics in high school biology were developed through the collaboration of high school teachers and university faculty and staff and were administered to 408 high school students in six classrooms. The content of instruction and testing was guided by State of Texas science objectives. Detailed teacher records describing daily classroom activities were used to operationalize two types of instruction: active learning, which used the labs; and traditional, which used the teaching resources ordinarily available to the teacher. Teacher records indicated that they used less independent work and fewer worksheets, and more collaborative and lab‐based activities, with active‐learning labs compared to traditional instruction. In‐class test data show that students gained significantly more content knowledge and knowledge of process skills using the labs compared to traditional instruction. Questionnaire data revealed that students perceived greater learning gains after completing the labs compared to covering the same content through traditional methods. An independent questionnaire administered to a larger sample of teachers who used the lab‐based curriculum indicated that they perceived changing their behaviors as intended by the student‐centered principles of the labs. The major implication of this study is that active‐learning–based laboratory units designed and developed collaboratively by high school teachers and university faculty, and then used by high school teachers in their classrooms, can lead to increased use of student‐centered instructional practices as well as enhanced content knowledge and process learning for students. © 2007 Wiley Periodicals, Inc.

This study compared the relationships of self‐efficacy and reasoning ability to achievement in introductory college biology. Based on the hypothesis that developing formal and postformal reasoning ability is a primary factor influencing self‐efficacy, a significant positive correlation was predicted between reasoning ability and degree of self‐efficacy to complete biological tasks. Further, reasoning ability was predicted to be more highly correlated with course achievement than self‐efficacy. The study involved pre‐ and posttesting 459 introductory biology students. Both self‐efficacy and reasoning ability increased during the semester. As predicted, self‐efficacy and reasoning ability were positively correlated. Depending on the nature of the achievement measure, reasoning ability accounted for some 15 to 30 times more variance in achievement than self‐efficacy. Also, as predicted, reasoning ability was a strong predictor of self‐efficacy, but self‐efficacy was not a strong predictor of reasoning ability. Self‐efficacy estimates and achievement were higher for the concrete tasks than for the formal tasks and higher for the formal tasks than for the postformal tasks. In general, students tended to overestimate their abilities to carry out the concrete, formal, and postformal tasks. Results support the study's working hypothesis that intellectual development continues for some students during the college years, that a postformal level of intellectual development exists, and that reasoning ability is a primary factor influencing both self‐efficacy and achievement. Student overestimation of their abilities may contribute to complacency, lack of effort, and to less than optimal achievement. Consequently, it may be advantageous early in the semester to provide students with particularly challenging tasks that “shock” them out of their complacency and perhaps increase their effort, their reasoning skills, and their achievement. © 2006 Wiley Periodicals, Inc.

This study had the goal of investigating the association among elementary students' (N = 276) science and math beliefs and the relationship between those beliefs and teachers' ratings of mathematical and science understanding. Results of structural path analysis indicate that in science, intellectual risk‐taking (IRT; the willingness to share tentative ideas, ask questions, attempting to do, and learn new things) was positively related to teachers' ratings of science understanding, while creative self‐efficacy (CSE) beliefs (i.e., students' confidence in their ability to generate ideas and solutions in science) were indirectly related (working through IRT). Results also indicate that students' scientific certainty beliefs (i.e., the belief that science knowledge is stable, fixed, and represented by correct answers) were negatively related to teachers' ratings of science understanding. With respect to math, results indicate that students' CSE beliefs were positively related to teachers' ratings of math understanding; whereas students' mathematical source beliefs (i.e., believing that math knowledge originates from external sources) were negatively related. © 2012 Wiley Periodicals, Inc.

The results of the Progress in International Reading Literacy Study (PIRLS 2001) were published in 2003. In addition to data about the reading achievements of 10‐year‐olds in 35 countries, PIRLS 2001 also collected questionnaire information from children, their teachers, headteachers and parents. The results showed not just how well students can perform in various reading tasks, but also the relationship between reading abilities and other characteristics, including the characteristics of their homes and schools, the students' attitudes to reading, reading enjoyment, self‐confidence, engagement and perceptions of their reading abilities. Surprisingly enough, children in England were reported as having poor attitudes to reading, compared to children in many other countries, despite high achievement on the reading tests. This paper raises some concerns about the interpretation of results from the study, suggesting a more complex picture than that presented in the summary index published in 2003. Our secondary analysis of the attitude and achievement data from PIRLS shows that pupils with low ability levels have misunderstood the questions which tested their attitudes towards reading. The authors point out that caution is needed when making cross‐country comparisons to avoid naïve approaches to interpretation. 相似文献

There is a need to identify students' early attitudes toward mathematics and science to better support their long-term persistence in science, technology, engineering, and mathematics (STEM) careers. Seventh graders from a nationally representative sample (N = 2,861) were classified based on their responses to questions about their attitudes toward mathematics and science using latent class analysis. Four distinct groups of students that differed in terms of their attitudes were identified. There were relationships between attitudinal group membership, demographic characteristics, mathematics and science achievement, and STEM career attainment. Females and underrepresented minorities were more likely to be in the positive attitude group. However, despite these early positive attitudes, females and underrepresented minorities were less likely to be employed in a STEM career some 20 years later. Information about student interests organized in this manner can be used to better target specific interventions to support and encourage persistence in STEM careers. 相似文献

The reported study investigated students’ perceptions of their high-performing classmates in terms of intelligence, social skills, and conscientiousness in different school subjects. The school subjects for study were examined with regard to cognitive, physical, and gender-specific issues. The results show that high academic achievements in particular school subjects lead to negative reactions in the peer group whereas high achievements in other school subjects result in positive peer reactions. In contrast, the respondents’ gender and the gender of the successful classmates had little influence on student perceptions of high achievers. The results are discussed in regard to their implications for gifted education. 相似文献

This study follows an ethnically and economically diverse sample of 33 high school students to explore why some who were once very interested in science, engineering, or medicine (SEM) majors or careers decided to leave the pipeline in high school while others persisted. Through longitudinal interviews and surveys, students shared narratives about their developing science identities, SEM participation and aspirations. In analysis, three groups emerged (High Achieving Persisters, Low Achieving Persisters, and Lost Potentials), each experiencing different interactions and experiences within science communities of practice in and outside of school and within the extended family. These different microclimates framed students' perceptions of their SEM study, abilities, career options, and expected success, thereby shaping their science identities and consequent SEM trajectories. School science was often hard and discouraging; there were very few science advocates at school or home; and meaningful opportunities to work with real science professionals were scarce, even in schools with science or health academies. Students expressed positive attitudes toward science and non‐science pursuits where they experienced success and received support from important people in their lives. Results underscore the key role communities of practice play in career and identity development and suggest a need for interventions to help socializers better understand the value and purpose of science literacy themselves so as to encourage students to appreciate science, be aware of possible career options in science and enjoy learning and doing science. © 2009 Wiley Periodicals, Inc.

The objective of the present study was to better understand a relatively under-researched topic, namely, undergraduate students’ attitudes towards mistakes and how their attitudes relate to academic achievement. A series of online surveys were administered to a sample of 207 first- and second-year undergraduate students. Using structural equational modelling, a hypothesised model was proposed to evaluate the following four research questions: (1) What is the effect of students’ trust in their instructor on students’ achievement goals? (2) What is the relationship between students’ achievement goals and their attitudes towards mistakes? (3) Is students’ attitudinal behaviour towards mistakes predictive of their perception of feedback? (4) Is students’ openness to discussing mistakes (ODM) and attitudinal behaviours predictive of their academic achievement? Both direct and indirect effects were found. Direct effects indicated that students’ trust in their instructor predicted achievement goals, students’ achievement goals differentially predicted attitudes towards mistakes, students’ ODM predicted perceptions of feedback, and students’ attitudinal behaviours predicted academic achievement. Students’ trust in their instructor and achievement goals had indirect effects on students’ achievement. 相似文献

The changing landscape of learning in graduate leadership programs has given way to the potential of online development programs. Currently, a lack of research exists that describes the role of the online leader, particularly in academic programs that utilize mentors as well. Identification and exploration of the leadership role in an online environment given the structural elements of mentorship and academic coursework, then becomes the context of this article. A case study using a systems framework of input-process-output=output was conducted to investigate a program of international collaboration, networking and mentoring relationships that attempted to unite leaders to prepare schools for globalization. What developed within the overall design was the identification of three levels of leaders that were involved in this program: Student (participant) leaders, process leaders, and instructor leaders that struggled to define identity roles within the virtual realm. A clear need for purpose, identification and role clarity to scaffold the virtual experience and fortify the mentoring process surfaced from the experi ences within this case. Further research and development will be needed to successfully design programs for leaders that will meet practical, relevant needs while establishing engaging, collaborative, interdependent relationships to affect the local environment and satisfy the necessary academic criteria. 相似文献

To examine how school characteristics are tied to science and engineering views and aspirations of students who are underrepresented in science and engineering fields, this mixed‐methods study explores relationships between aspects of students' science identities, and the representation of women among high school science teachers. Quantitative analyses tested the hypothesis that percent female faculty would have a positive effect on girls' science interests, and perceptions in particular, given the potentially greater availability of women role models. Findings indicate that percent female science faculty does not have an effect on a range of science measures for both male and female students, including the ways in which they understand scientific practice, their science self‐concept, and their interest in science‐related college majors. As qualitative data demonstrate, this could reflect practical constraints at schools where female faculty are concentrated and narrow perceptions of science teachers and “real” science. © 2007 Wiley Periodicals, Inc.

Mixed methods research conducted across three semesters in introductory college geology classes (n = 187, 190, 138) attempted to ascertain whether integrated study of petrified wood could serve as a portal to improved student geobiological understanding of fossilization, geologic time, and evolution. The Petrified Wood Survey? was administered as a preinstructional and postinstructional assessment in control and experimental classes; the experimental class received integrated petrified wood instruction. Paired t tests of differences in students' pre‐ and postinstructional scores for control and experimental groups revealed significance (α = 0.05, effect size = 0.79, confidence interval 0.56–1.01). The students with integrative study showed greater knowledge gains about petrified wood's abundance, properties, nature, location, and geologic time. However, understanding of fossilization geochemistry remained problematic for both groups. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 44: 1011–1035, 2007 相似文献

Although countries worldwide are emphasizing the importance of science education for technological development and global economic competition, comparative findings from standardized international student assessments reveal a huge gap in science scores between developed and developing countries. Certain developed economies too have made little progress in raising science achievement over the past decade. Despite school improvement being placed high on the policy agenda, the results of such actions have been poor. Therefore, there is a need to explore additional ways in which science achievement can be enhanced. This study focuses on the family and examines whether parents' attitudes towards science (how much they value science and the importance they place on it) can influence their children's science achievement. Individual- and school-level data are obtained from the Program for International Student Assessment 2006 survey for 15 Organisation for Economic Co-operation and Development (OECD) and non-OECD countries. Hierarchical linear modelling is employed to estimate the equations. The findings indicate that parents' attitudes towards science have a positive and statistically significant effect on science achievement, after controlling for other important student- and school-level variables. Moreover, students from poor backgrounds appear to benefit from more positive parental science attitudes as much as students from high socioeconomic status, such that equality of student achievement is not affected. This study recommends that schools and teachers encourage parents to play a more pro-active role in their children's science education, as well as educate parents about the importance of science and strategies that can be adopted to support their children's science learning. 相似文献

Competition in the market is a perennial and ever‐increasing problem for independent schools. How schools can meet this pressure and find ways to attract (the best) students is a continuing question and one that will get more onerous as the government funding for education is, in relative terms, decreasing. One of the ways in which schools can show their worth is the attraction of the best teachers and being able to show potential clients how their staff contribute to the academic success of their graduating students. This study considers the relationship between teachers’ attitudes toward their work and the expectations and the extent to which their attitudes and expectations predict the academic achievements of their final year students. Results found that academic achievement is enhanced when school leadership provides an academically oriented context where values and expectations of high academic achievement are part of the school culture. Other teacher variables found to improve academic achievement are the teachers’ need for greater input into decision‐making at their schools; less formalisation of rules, procedures and process; and support through personnel, facilities, finances, equipment and resources. 相似文献

The purpose of this study was to explore the personal stories of men who selected careers in science, technology, engineering, or mathematics (STEM) to better understand the ways in which their self‐efficacy beliefs were created and subsequently influenced their academic and career choices. Analysis of 10 narratives revealed that mastery experience was the primary source of the men's self‐efficacy beliefs. These results are compared to those from Zeldin and Pajares' earlier study involving women in STEM careers. For women, social persuasions and vicarious experiences were the primary sources of self‐efficacy beliefs. Together, these findings suggest that different sources are predominant in the creation and development of the self‐efficacy beliefs of men and women who pursue STEM careers. The self‐efficacy beliefs of men in these male‐dominated domains are created primarily as a result of the interpretations they make of their ongoing achievements and successes. Women, on the other hand, rely on relational episodes in their lives to create and buttress the confidence that they can succeed in male‐dominated domains. Findings were consistent with the theoretical tenets of A. Bandura's social cognitive theory. © 2008 Wiley Periodicals, Inc. J Res Sci Teach 45: 1036–1058, 2008 相似文献
