Science career preferences of junior high school-aged students, while not stable predictors of ultimate career choice, do serve to direct and maintain individuals along the paths to careers in science. In this study, factors relevant to science career preferences of black eighth grade students were investigated. This issue is of particular import to blacks since they are severely underrepresented in the scientific fields. The sample consisted of 113 males and 148 females in an inner city junior high school. The Science Career Preference Scale, the Peabody Picture Vocabulary Test, and the Self-Concept of Ability Scale (Form B-Science) were administered. Mathematics and science grades were obtained from class rating sheets. Treatment of the data involved multiple regression analysis according to a hierarchical model. Results showed that of all the independent variables, sex was the strongest predictor of science career preferences, accounting for 25% of the criterion variance. The findings suggest that early adolescent science career preferences are related more to interests that are consonant with sex-role considerations than realistic assessment of mathematics or science achievement.  相似文献

This article examines gender differences in science achievements and attitudes during the middle grade, when our nation's scientific pipeline begins to emerge. It uses data from a large, nationally representative sample of eighth-grade students (NELS-88). The findings show that in these grades female students do not lag behind their male classmates in science achievements tests, grades, and course enrollments. Actually, some female students have higher probabilities of enrolling in high-ability classes than males. However, female students have less positive attitudes toward science, participate in fewer relevant extracurricular activities, and aspire less often to science careers than males. Students' science attitudes and career interests vary according to students' gender as well as their racial or ethnic background. These findings emphasize the need to further examine the interrelationships between gender and race or ethnicity in our efforts to understand the processes leading to women's limited participation in science-related careers.  相似文献

The Educational and Career Interest scale, a self-report instrument measuring high school students’ educational and career interest in STEM, was developed and validated in two studies conducted during 2010 and 2011. Study 1 included data from 92 high school students, in which exploratory factor analysis (EFA) was conducted with an initial item pool of 20 items. EFA identified three factors: educational and career interest in science, educational and career interest in technology, and educational and career interest in mathematics. Study 2 utilized data from 658 students to revisit the three-factor model using confirmative factor analysis. The two studies provide strong evidence that the scale is both valid and reliable.  相似文献

A one‐credit seminar on controversies in food science and human nutrition was a platform to introduce students to learning frameworks for thinking‐like‐a‐scientist. We hypothesized that explicitly engaging students in thinking about their thinking abilities within these frameworks would enhance their self‐perception of scientific thinking, an important general ability for food scientists. Our objectives were to assess thinking‐like‐a‐scientist using a student self‐assessment survey, and analyze their self‐reflections for evidence of such thinking. For students enrolled in one of the offerings of this course among 5 semesters from 2012 to 2014, differences in scores on a survey instrument for thinking‐like‐a‐scientist from the beginning to the end of the course showed gains in self‐assessed abilities (N = 21 to 22 students/semester). In each of the first 2 semesters in which we introduced thinking‐like‐a‐scientist frameworks, students thought they were better at defining problems scientifically by 13% to 14%. In the 3rd course offering, students’ self‐assessment of their abilities to seek evidence improved by 10%. In the 4th and 5th semester course offerings, students’ self‐assessed abilities to develop plans based on evidence improved by 7% to 14%. At the end of each semester, students’ self‐reflections on scientific thinking (N = 20 to 24/semester) included specific reference to asking questions (45% to 65% of reflections) and making plans based on evidence (26% to 50% of reflections). These data support the usefulness of self‐reflection tools as well as specific learning frameworks to help students to think about and practice thinking‐like‐a‐scientist.  相似文献

Students’ science-related career expectations are important for predicting their future science, technology, engineering, and mathematics (STEM)-related educational and occupational attainments. This study examines the degree to which standards-based external examinations are associated with a student’s propensity for pursuing science-related professional occupations. The science-related fields included in the analysis are mathematics, physical and life science, and engineering/computing. Three-level hierarchical generalized linear models are employed to analyse international survey and student achievement data from the Programme for International Student Assessment (PISA). The analyses show that students in national education systems that require standards-based external examinations have lower expectations for science-related professional careers than students in the systems that do not use such examinations. This negative association remained constant by gender as well as across levels of science performance. From an educational policy point of view, the results suggest the negative consequence of standards-based external exams in fostering students’ interests in pursuing science-related careers.  相似文献

Students' lack of interest in studying science and in science-related careers is a concern in the UK and worldwide. Yet there is limited data, particularly longitudinal, on the sources and development of science-related aspirations. In response, the ASPIRES (Science Aspirations and Career Choice: Age 10–14) longitudinal study is investigating the development of students' educational and occupational aspirations over time. In the first phase of the project, a questionnaire exploring science-related aspirations and interests was completed by over 9,000 primary school students across England. This survey allowed us to explore possible associations between attitudes and aspirations, links which have not been investigated in previous attitudinal studies of this scope. Overall, students expressed positive attitudes to science, reported positive parental attitudes to science and held very positive images of scientists. Multilevel modelling analyses revealed that aspirations in science were most strongly related to parental attitudes to science, attitudes to school science and self-concept in science, and are also associated with students' gender, ethnicity and cultural capital. However, the images students held of scientists were not as closely related to aspirations. These factors are discussed in more detail within the paper, alongside a consideration of possible school-related effects.  相似文献

This article describes the development of an instrument – the Career and Talent Development Self‐Efficacy Scale (CTD‐SES) – for assessing students’ self‐efficacy in applying life skills essential for personal talent development, acquisition of positive work habits, and career exploration. In Study 1, data were obtained from a large sample of Chinese middle‐school students (N=15,113) in Grades 7–9 in Hong Kong. The CTD‐SES is an 18‐item questionnaire with subscales containing items that address students’ orientations toward developing their own talents, acquiring and applying positive work habits, and exploring their career possibilities. Evidence is provided for internal consistency, temporal stability, and factor structure of the CTD‐SES. Goodness of fit statistics provided support for a three‐primary‐factor‐plus‐higher‐factor model, and this solution was used in the statistical analyses. The data also indicated that students with plans for university study reported significantly higher scores than those without on all three domains of career and talent development. In Study 2 (N=308) Grade 10 high‐ability students’ scores in CTD‐SES were correlated with scores in career decision self‐efficacy and academic performance. The development and validation of CTD‐SES is the first step toward investigating career exploration, work habits, and talent development among Asian middle‐school adolescents.  相似文献

The purpose of this study was to investigate the relationship of subject matter knowledge in science and the patterns of entering, leaving, and remaining in the teaching profession among college graduates trained to be science teachers. To do this, National Teachers Examination (NTE) Biology and General Science test scores served as the proxy for science subject matter knowledge for a sample of 83 individuals initially certified to teach science in North Carolina during a 4-year period of time. The career patterns of these individuals as science teachers were documented and their work status was identified as nonrecruits, defectors, or career teachers. Using maximum likelihood logistical regression (MLOGIT) analysis, the relationship between career status (the dependent variable) and knowledge of science, race, gender, and the race and status (public or private) of the college from which they graduated was investigated. Of the 83 individuals in the analysis, 30 (36.1%) were identified as nonrecruits, 31 (37.3%) as defectors, and 22 (26.5%) as career teachers. Science subject matter knowledge was found to have a significant (p = .01) effect on the likelihood of being a nonrecruit versus a career teacher. The magnitude of this effect was also important, with the likelihood of being a nonrecruit increasing 120% for every 100-point increase in score on the NTE Biology and General Science tests. Science subject matter knowledge also had a significant effect (p = .05) on the likelihood of being a defector versus a career teacher, with the likelihood increasing 80% for every 100-point increase in NTE Biology and General Science scores. No other significant relationships were found.  相似文献

Many biomedical research universities have established outreach programs for precollege students and teachers and partnerships with local school districts to help meet the challenges of science education reform. Science outreach programs held in university research facilities can make science more exciting and innovative for high school students and can offer them much more insight into the nature of science and laboratory research than is available in most high school science courses. This paper describes a long-term follow-up study of high school students enrolled in the Summer Science Academy program at the University of Rochester to investigate the program's impact on students' perceived abilities in higher level science courses, on participation in extracurricular science programs, as well as the program's impact on student interest in pursuing a career in science. Students' exposure during SSA to advanced laboratory techniques and their participation in authentic science investigations provided them with a very positive hands-on experience. Students who attended the program indicated that it provided a positive influence on their performance in advanced science courses, as well as their decision to participate in other science programs and their desire to pursue a career in science.  相似文献

A project designed to foster the full and fair participation of girls in high-school science classes addressed obstacles, both perceived and actual, to equal participation. In order to modify existing classroom techniques and environments, a Teacher Intervention Program was designed. By means of a workshop and periodic personal communications, teachers were sensitized to the importance of a stimulating, gender-free learning environment. In addition, they were presented with a variety of methods and materials which had been shown to encourage girls in science. Twelve teachers, who were selected randomly, taught in diverse communities throughout one Midwestern state. The subjects tested were students in 24 general biology classes taught by the 12 teachers. Although both qualitative and quantitative measures were used during the research, only the quantitative results are discussed in this paper. Using ANOVA's, treatment group by student sex, a comparison of the mean scores was made for all students, as well as for all females and for all males. The results indicated that the experimental group, compared to the control group, had significantly higher mean scores on tests of attitudes toward science, perceptions of science, extracurricular science activities, and interest in a science-related career.  相似文献

Typically, mathematics and science are seen as linked together, where both subjects involve numbers, critical thinking, and problem solving. Our study aims to develop a better understanding of the connections between student’s achievement scores in mathematics and science, student gender, and self-efficacy. We used the Trends in International Mathematics and Science Study 2007 eighth grade data to answer our research questions and were able to demonstrate that when controlling for self-efficacy, there is a statistically significant difference in the achievement scores between males and females by subject, where females score higher Algebra, but males score higher in the other mathematics subjects. Likewise, we were also able to demonstrate that there is a statistically significant difference in the achievement scores in Earth Science, Physics, and Biology, between males and females where males score higher in science subjects. In both mathematics and science examinations, we controlled for self-efficacy where in mathematics females hold lower self-efficacy then males and in science there is no difference between females and males in terms of self-efficacy. We conjecture that mathematics and science classrooms that consider self-efficacy may impact student’s achievement scores by subject, which can ultimately impact career choices in mathematics- and science-based fields.  相似文献

The number of students in the United States choosing science, technology, engineering or mathematics careers is declining at a time when demand for these occupations is rapidly increasing. Numerous efforts have been undertaken to reverse this trend, yet results are uncertain. One’s attitude is key to many choices one makes, and this includes, for many, what career is pursued. Hence, teachers, informal science educators and researchers often wish to measure children’s attitudes towards science using a pretest and a posttest to determine the effects of a curriculum, an activity or an intervention. However, measuring children’s attitudes toward science has been problematic because of both the limited use of basic psychometrics in checking reliability and validity of instruments and the lack of a single construct of students’ attitudes towards science being surveyed. This article reports the development and testing of an instrument for measuring students’ science attitudes across several dimensions. Thirty-two scientists and teachers from the northeastern and south central United States participated in content validity trials. The instrument was field tested with 549 children (92 elementary-school students, 327 middle-school students and 130 high-school students) from 6 rural and suburban school systems located in the northeastern United States to determine inter-item reliability for each dimension. The resulting instrument, entitled My Attitudes Toward Science (MATS), has 40 items that measure four dimensions: (1) Attitude towards the subject of science; (2) Desire to become a scientist; (3) Value of science to society; and (4) Perception of scientists. The MATS, as a multidimensional instrument, can measure several facets of students’ attitude toward science and is designed to be used across grades levels and to be scored easily.  相似文献

Project Ga‐GEMS (Georgia's Project for Gifted Education in Math and Science) viewed the effect that placement in an integrated, hands‐on mathematics and science curriculum had on the achievement of academically talented high school students. For a two‐year period of time, students gifted in the areas of mathematics and science participated in a curriculum which incorporated higher‐level thinking skills and more real life laboratory experiences into mutually reinforcing mathematics and science lessons. After the conclusion of the two‐year program, Ga‐GEMS participants and a control group were given the mathematics and science sections of the ACT as they exited the tenth grade. The Ga‐GEMS students scored significantly higher on the Science Math Total, Pre‐Algebra/Elementary Algebra, Intermediate Algebra/Coordinate Geometry and Plane Geometry/Trigonometry sections of the ACT. To determine if the Ga‐GEMS students retained their higher scores throughout high school the SAT scores of both groups were compared as the students exited high school. Significant differences in the areas of total score and mathematics were noted. This study lends support for the use of a differentiated curriculum for educating gifted students in science and mathematics.  相似文献

Many researchers consider a lacking interest in science and the students' belief that science is too demanding as major reasons why young people do not strive for science-related careers. In this article, we first delineated a theoretical framework to investigate the importance of interest, self-concept, and school factors regarding students' career preferences. Then, we tested the expected effects on a sample of German 9th-grade students (N = 7,813). We focused on two school factors: the amount of (additional) science activities and the real-life applications in science classes. The multi-level analysis showed that school factors were highly relevant for the students' interest in science and science self-concept. In turn, interest in science and science self-concept affect the students' interest in science-related careers. We conclude that focusing on the link between individual and school characteristics is important for the understanding of students' interest in science-related careers.  相似文献

This article describes the development and validation of the Attitudes towards Climate Change and Science Instrument. This 63-item questionnaire measures students’ pro-environmental behaviour, their climate change knowledge and their attitudes towards school science, societal implications of science, scientists, a career in science and the urgency of climate change. The results from the pilot and the final study show the questionnaire meets validity and reliability criteria. A total number of 671 secondary school students from five European countries (France, Norway, Italy, The Netherlands and Spain) completed the questionnaire. The results of the principal components factor analysis show that all scales were unidimensional. Internal reliability using Cronbach’s alpha varies between 0.71 and 0.87. Concurrent validity was shown by younger students, females and students with high science grades scoring higher on several attitudes than respectively older students, male students, or students with low science grades. Overall, correlations show weak but significant relationships between science-related attitudes on the one hand and climate change- and environment-related attitudes on the other. Based on our findings, our instrument is useful for understanding the ways in which students think about science, scientists, climate change and the environment.  相似文献

Existing instruments in classroom environment research have limitations when subgroups are investigated or case studies of individual students conducted. This study reports the validation and development of a personal form of the Science Laboratory Environment Inventory which is better suited to such studies. Further, systematic differences between scores on the class and personal forms of the instrument are reported along with comparisons of their associations with inquiry skill and attitudinal outcomes.

Children using robotics for engineering, science, technology, and mathematics (CREST-M) is an ongoing curriculum creation and evaluation project developing math-focused science, technology, engineering, and mathematics (STEM) curriculum units that incorporate storytelling with math and are designed to be engaging for students from backgrounds traditionally underrepresented in STEM fields and to be appropriate for all ability levels including the gifted. This mixed-methods study evaluated one CREST-M unit, The Tale of the Monarchs, aligned to the Common Core State Standards: Mathematics (CCSS-M) for fourth- and fifth-grade fractions while incorporating all aspects of STEM. The unit includes an engineering design loop to help students create and program robots using LEGO WeDo 2.0. Students also use the scientific method in a problem-based learning (PBL) investigation in which they design and conduct experiments. The unit features a comprehensive storyline in which diverse characters solve real-world problems using STEM skills. The curriculum was evaluated through a CCSS-M aligned pre- and post-assessment of students’ understanding of fractions, the Cognitive Abilities Test Screening Form 7 (CogAT 7), and the Draw-a-Scientist pre- and post-assessment. The curriculum led to significant and meaningful gains in math achievement (Cohen’s d = 0.72) consistent for students at multiple ability levels (including high ability) and children from groups traditionally represented in STEM fields as well as those traditionally underrepresented (across gender, race, and socioeconomic status). In addition, the mental models of the career of a scientist that students articulated before the program were markedly more complex and less stereotypical following the program, indicating increased understanding of the career of a scientist.  相似文献

This study investigates the effects of an intensive 1-week Inquiry-Based Science and Technology Enrichment Program (InSTEP) designed for middle school-aged female students. InSTEP uses a guided/open inquiry approach that is deepened and redefined as eight sciences and engineering practices in the Next Generation Science Standards, which aimed at increasing female students’ interest in science and science-related careers. This study examined the effectiveness of InSTEP on 123 female students’ pre-assessment and post-assessment changes in attitudes toward science and content knowledge of selected science concepts. An attitude survey, a science content test with multiple-choice questions, written assignments, and interviews to collect data were all used to measure students’ attitudes and content knowledge. A within-group, repeated measure design was conducted, and the results indicated that at the post-intervention level, InSTEP increased the participants’ positive attitudes toward science, science-related careers, and content knowledge of selected science concepts.  相似文献
