The elementary level science methods course: Breeding ground of an apprehension toward science? a case study

Ethnographic research methodologies were used to examine the training of elementary education majors in science in an attempt to gain insight on whether or not their training in science contributes to the apprehension elementary teachers have toward science. The field study consisted of 14 weeks of weekly observations in the elementary education majors science methods class. Interviews with the students and the instructors as well as survey instruments to assess students' preparation in science were used. Two different approaches to the study of science, one content oriented, the other process oriented, may contribute to the students' confusion, insecurity, and avoidance of science. The students' perception that science is learning content, an objective of introductory level science courses, and the science methods class's objectives of teaching science as a process sets up an “antagonistic dilemma” between the two. Such “antagonistic dilemma” may be manifest in the lack of instructional time accorded to science by elementary educators. The type of science experiences an individual encounters influences their perceptions. To offset student perceptions developed in science courses which stress principally content, the students need science experiences which truly represent science as inquiry. New strategies for the training of elementary education majors in science need to be examined.     

Gender ratios in high school science departments: The effect of percent female faculty on multiple dimensions of students' science identities

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.

Gender,ethnicity, science achievement,and attitudes

Science achievement and attitudes were assessed for a series of students in Grades 3–12 representing the four major ethnic groups in Hawai'i (USA). It was found that more differences were accounted for by ethnicity and even grade than by gender; in addition, there was little interaction between ethnicity and gender. With respect to ethnicity, Caucasian and Japanese-American students outscored Hawaiians and Filipino Americans at all grade levels. Caucasians also expressed the most positive attitudes toward science and Japanese expressed the most positive perceptions of scientists; Hawaiians generally expressed the least positive perceptions. Younger students generally expressed more positive attitudes toward science but less positive perceptions of scientists compared to older students. Caucasians expressed the most positive perceptions of their own science ability and achievement. With respect to gender, there were no consistent differences in science achievement and very few in science attitudes and perceptions. The major differences were that males reported more experiences with physical science activities and also expressed a more male-stereotyped view of science than females, with some variation by ethnicity and grade. There were differences in enrollment in advanced science and mathematics classes in that females were more likely than males to enroll in many, but for both genders the major reason was college admission: Japanese students were most likely and Hawaiians least likely to indicate science interest as a reason. Findings are discussed within the context of cultural ecology and feminist social theory. © 1996 John Wiley & Sons, Inc.     

Bringing Up Girls in Science (BUGS): The Effectiveness of an Afterschool Environmental Science Program for Increasing Female Students’ Interest in Science Careers

Bringing Up Girls in Science (BUGS) was an afterschool program for 4th and 5th grade girls that provided authentic learning experiences in environmental science as well as valuable female mentoring opportunities in an effort to increase participants’ academic achievement in science. BUGS participants demonstrated significantly greater amounts of gain in science knowledge as measured by the Iowa Test of Basic Skills in Science (ITBS-S). The original BUGS participants and contrasts have now completed high school and entered college, allowing researchers to assess the long-term impact of the BUGS program. Fourteen former BUGS participants completed two instruments to assess their perceptions of science and science, technology, engineering, and mathematics (STEM) careers. Their results were compared to four contrast groups composed entirely of females: 12 former BUGS contrasts, 10 college science majors, 10 non-science majors, and 9 current STEM professionals. Results indicate that BUGS participants have higher perceptions of science careers than BUGS contrasts. There were no significant differences between BUGS participants, Science Majors, and STEM professionals in their perceptions of science and STEM careers, whereas the BUGS contrast group was significantly lower than BUGS participants, Science Majors, and STEM Professionals. Additional results and implications are discussed within.     

Grade 10 Students' perceptions of and attitudes toward science teaching and school science

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.     

Teachers’ and pupils’ perceptions of science–technology learning environments

During recent decades, educational research has dealt with the contribution of the learning environment to the accomplishment of educational goals, such as improvement of academic achievement and motivation. In this research, an intervention program was implemented into the learning environment of science–technology classes at the junior high school level (Grades 7–9, 12–15 years old) in Israel. The intervention included a three-year workshop involving 224 hours each year. The teachers (N = 22) were required to reflect on their experiences using a portfolio that described their actual teaching experiences for relevant discussions at the workshop. Quantitative and qualitative tools were used to examine the teachers’ implementation of new teaching/learning and assessment methods or new subject matter, that were addressed by the workshop in their classes, and to identify learning environment characteristics and learning outcomes according to teachers’ perceptions. Differences were found between teachers’ and pupils’ perceptions of the impact of learning environment characteristics on learning outcomes.     

Science motivation questionnaire II: Validation with science majors and nonscience majors

From the perspective of social cognitive theory, the motivation of students to learn science in college courses was examined. The students—367 science majors and 313 nonscience majors—responded to the Science Motivation Questionnaire II, which assessed five motivation components: intrinsic motivation, self‐determination, self‐efficacy, career motivation, and grade motivation. Exploratory and confirmatory factor analyses provided evidence of questionnaire construct validity. The motivation components, especially self‐efficacy, were related to the students' college science grade point averages. The science majors scored higher than the nonscience majors on all of the motivation components. Among both science majors and nonscience majors, men had higher self‐efficacy than women, and women had higher self‐determination than men. The findings suggest that the questionnaire is a valid and efficient tool for assessing components of students' motivation to learn science in college courses, and that the components play a role in students' science achievement. © 2011 Wiley Periodicals, Inc.

Taiwanese science students' and teachers' perceptions of the laboratory learning environments: Exploring epistemological gaps

The purpose of this study was to explore the differences between science students' and teachers' perceptions of laboratory environments. More than 1000 junior high school students and their science teachers in Taiwan were surveyed. The students showed much more dissatisfaction with approaches to laboratory activities than their teachers. They preferred a much more student-cohesive, open-ended, integrated and rule-clear laboratory environment than their teachers expected or preferred. However, the teachers sampled showed higher preferences for better equipment and material environments for laboratory work than did their students. Data from follow-up interviews with participant teachers suggested that epistemological views about science might be one of the important factors causing differences in perceptions between students and teachers of laboratory learning environments.     

A phenomenological study of community college students’ experiences with mentor teachers*

The aims of our current study were to (1) explore how community college science and mathematics majors made meaning of their experiences with mentor teachers as part of an early field experience and (2) understand the ways students’ experiences with mentors influenced their interest in teaching. Using interviews and written reflection activities, a qualitative phenomenological approach was used to understand and describe the meaning of the lived mentoring experiences of 17 community college science and mathematics majors. Five themes were identified to describe community college students’ experiences with mentor teachers in elementary, middle and high schools in a high-needs school district: (a) role modeling, (b) mutual respect and honesty, (c) responsiveness and guidance, (d) approachability and relatedness, and (e) broadening and shifting perspectives. Findings point to the potential of early relationships with mentor teachers as a means to shape community college students’ interest in teaching science or mathematics.     

A qualitative study of middle school students' perceptions of factors facilitating the learning of science: Grounded theory and existing theory

The purpose of this study was to explore middle school students' perceptions of what factors facilitated their learning of science. Florida's Educational Reform Act of 1983 funded programs providing the state's precollege students with summer learning opportunities in science. mathematics, and computers. The programs were intended to encourage the development of creative approaches to the teaching of these disciplines. Under this program, between 50 and 60 high-achieving middle school students were in residence on the University of South Florida campus for 12 consecutive days of study in the World of Water (WOW) program. There were two sessions per summer involving a total of 572 participants. Eighi specially trained teachers were in residence with the students. Between 50 and 70 experts from the university, government. business, and industry interacted with the students each year in an innovative science/technology/society (STS) program. An assignment toward the close of the program asked students to reflect on their experiences in residence at the university and write an essay comparing learning in the WOW program to learning in their schools. Those essays were the base for this study. This was a qualitative study using a discursive approach to emergent design to generate grounded theory. Document review, participant observation, and open-ended interviews were used to gather and triangulate data in five phases. Some of the factors that middle school students perceived as helpful to learning science were (a) experiencing the situations about which they were learning; (b) having live presentations by professional experts; (c) doing hands-on activities: (d) being active learners; (e) using inductive reasoning to generate new knowledge; (f) exploring transdisciplinary approaches to problem solving; (g) having adult mentors; (h) interacting with peers and adults; (i) establishing networks; (j) having close personal friends who shared their interest in learning; (k) trusting the individuals in their learning environment, including adults and students; and (1) experiencing a sense of self-reliance. The preceding information was used to generate a series of hypotheses which were woven into a theoretical model. This model suggests that middle school science teacher education would be enhanced by helping prospective and in-service teachers develop and implement strategies that build trust, provide immersion in learning, and use inductive reasoning. This model is currently being used as the theoretical base to convert a traditional junior high school in the South to a middle school.     

A comparison of actual and preferred classroom environments as perceived by science teachers and students

This study of perceptions of classroom environment is distinctive in that, first, it made use of two instruments (the Individualized Classroom Environment Questionnaire and Classroom Environment Scale) which have had very little use in prior science education research and, second, it involved assessment not only of student perceptions of actual environment, but also of student perceptions of preferred environments and teacher perceptions of actual environment. Administration of these instruments to a sample of 2175 junior high school students in 116 classes revealed that the environment scales exhibited satisfactory internal consistency reliability and discriminant validity in each of the three forms (student actual, student preferred, and teacher actual), and that there were some fascinating systematic differences between the profiles of environment scale scores obtained for the different forms. In particular, it was generally found that students preferred a more favorable classroom environment then was perceived as being actually present and that teachers perceived the environment of their classes more favorably than did students in the same classrooms.     

The influence of gender,ethnicity and rurality upon perceptions of science

This paper reports an investigation into gender, ethnicity and rurality on Fijian students’ perceptions of science. A questionnaire was administered to a large sample of Form 5 classes. All students had completed a four year integrated "Basic Science" course in the junior secondary school and were continuing their studies in the upper secondary school. The responses were analysed to determine the significance of gender, ethnicity and rurality on the students’ perceptions of science, attitudes to science in the world and to science in the school curriculum. Specializations: gender issues and affective aspects of science and technology education. Specializations: Constructivism in science education, development education and gender issues.     

Effect of women science career role models on early adolescents' attitudes toward scientists and women in science

In order to change the attitude of early adolescent female and male students toward scientists and women in science, students in the middle school/junior high grades were exposed over a two months' period to women science career role models as part of their science instruction. This treatment positively affected the students' attitude toward scientists and toward women in science. It is suggested that teachers of science in the middle school/junior high should periodically bring community resource people who use science in their careers to the classroom to act as role models and that women should be included among this group so that the attitudes of both male and female students toward scientists and women in science might be improved.     

Gender disparities in science and engineering in Chinese universities

Gender disparities in science and engineering majors in Chinese universities have received increasing attention from researchers and educators in China in recent years. Using data from a national survey of college students who graduated in 2005, this study documents gender disparities in enrollment and academic performance in science and engineering majors, and explores gender disparities in initial employment experiences of science and engineering graduates. It finds that females lag far behind males in enrollment in science and engineering majors overall. However, females actually are more represented than males in some majors such as mathematics and chemistry though the reverse is true for other science and engineering majors. Also, in science and engineering majors, females perform better than males in both general course grades and in English competency tests. Male science and engineering graduates have a clear advantage over their female counterparts in initial employment after graduation: they have a high employment rate, a higher starting salary, and are more likely to be employed in such jobs as business management and technical specialist. The male advantage in employment rate and starting salary persists even after controlling for other factors.     

Progression in learning science balanced forces

This article is linked to the last in its intelligent concern for the purposes of activities (“play”; “building with apparatus”) that can too often become part of the “routine” of a classroom. She starts with her own sensitive observations of what children do in her own classroom and enables us to see the value of structured use of play materials. With our current concerns for science, design and technology teaching in junior and secondary schools, it is, perhaps, a timely reminder of those subjects' starting points.     

Perception shapes experience: The influence of actual and perceived classroom environment dimensions on girls’ motivations for science

The classroom environment influences students’ academic outcomes, but it is often students’ perceptions that shape their classroom experiences. Our study examined the extent to which observed classroom environment features shaped perceptions of the classroom, and explained levels of, and changes in, girls’ motivation in junior secondary school science classes across two school terms. Girls have been found to feel less capable than boys and to under-participate in science classrooms, even though their achievement levels are similar. Four teachers and five of their classrooms of students (N = 52) reported their perceptions of the classroom environment, and trained observers rated the ‘actual’ classroom environment. Students also completed questions regarding their motivations for science at both time points. Hierarchical linear modelling showed that students’ perceptions of classroom structure were very important and exerted significant influence on science motivations. All of the six observed classroom dimensions affected students’ extrinsic utility value, via perceptions of structure. Other classroom dimensions showed particular patterns of relationship with motivations. Teachers’ perceptions of the classroom environment were often more positive than those of the students, which is congruent with previous research. The findings have implications for retaining girls in science and, thereby, addressing the gender gap in science-related vocations.     

Evolution and validation of a personal form of an instrument for assessing science laboratory classroom environments

The research reported in this article makes two distinctive contributions to the field of classroom environment research. First, because existing instruments are unsuitable for science laboratory classes, the Science Laboratory Environment Inventory (SLEI) was developed and validated. Second, a new Personal form of the SLEI (involving a student's perceptions of his or her own role within the class) was developed and validated in conjunction with the conventional Class form (involving a student's perceptions of the class as a whole), and its usefulness was investigated. The instrument was cross-nationally fieldtested with 5,447 students in 269 senior high school and university classes in six countries, and cross-validated with 1,594 senior high school students in 92 classes in Australia. Each SLEI scale exhibited satisfactory internal consistency reliability, discriminant validity, and factorial validity, and differentiated between the perceptions of students in different classes. A variety of applications with the new instrument furnished evidence about its usefulness and revealed that science laboratory classes are dominated by closed-ended activities; mean scores obtained on the Class form were consistently somewhat more favorable than on the corresponding Personal form; females generally held more favorable perceptions than males, but these differences were somewhat larger for the Personal form than the Class form; associations existed between attitudinal outcomes and laboratory environment dimensions; and the Class and Personal forms of the SLEI each accounted for unique variance in student outcomes which was independent of that accounted for by the other form.     

Learning science by doing science: an authentic science process-learning model in postsecondary education

Research on understanding the full extent that an authentic science research experience engages students in how scientists think and act is sparse. ‘Learning-science-by-doing-science’ (LSDS) is an emerging self-guided process-learning model in postsecondary science education. It offers authentic science research opportunities that drive students to think and act like scientists. This study investigates the LSDS approach as a potential model for science learning at postsecondary level and aims to answer a main research inquiry – what are the students’ and teaching staff’s perceptions of students’ learning gains and the quality of their learning experiences in an authentic research environment within the LSDS model? To answer this question, data were collected from the students, alumni, instructors, teaching assistants and the program director via questionnaires, focus groups and interviews. Students’ and staff’s lived experiences and their perceptions on their authentic research experiences within the LSDS model were used to articulate the key attributes and stages of the LSDS model. The outcomes of this study can be used to help other science programs implement similar authentic research process learning approaches in their own contexts.
