Middle and secondary science textbooks have long been a primary support for instruction, often leading to heavy emphasis on domain‐specific vocabulary. A longitudinal study was conducted to compare vocabulary loads of science textbooks published since 2010 to results of two previous studies going back to 1983. In each study, textbooks chosen represent convenience samples of commonly used middle and secondary science textbooks. Vocabulary emphasis in science textbooks remains high, and may present a problem for struggling readers and English language learners (ELL). Some vocabulary loads were found to approach or even exceed recommended limits for vocabulary instruction in modern foreign language courses. Also, science vocabulary can present an additional challenge for native English speakers and ELLs since many terms have no common colloquial English or native language equivalents. Recommendations for how to promote effective science vocabulary development are provided. Overall, over three decades there has been little change in heavy emphasis on vocabulary in middle and secondary science textbooks.  相似文献

The attitudinal perceptions of successful college science students regarding their junior high and high school science experiences were compared with those of successful nonscience students. Particular attention was paid to recollections of teacher personality attributes and instructional methodology. Results indicate that science students were especially motivated by knowledgeable, enthusiastic, communicative, committed, friendly, competent, and creative science teachers, whereas the nonscience group preferred patient, knowledgeable, congenial, friendly, supportive, and enthusiastic instructors. Both groups agreed that, although traditional methods (textbooks, lectures, quizzes/tests) dominated their science experiences, their preferred instructional strategies included more dynamic methods, including laboratory activities, teacher demonstrations, and discussions. Both groups also agreed that high school science courses provided a closer match than did junior high/middle school courses in providing their preferred teacher attributes and instructional methods. Results supported the observation that, even for these academically gifted students, interest in science is relatively depressed during the junior high/middle school years. It was concluded that, although endogenous variables act in concert, the quality of the student-teacher interaction exerts the greatest influence on student attitudes, particularly if those students are not already “science-friendly.” Instructional implications are discussed.  相似文献

This study aimed to examine the representations of nature of science (NOS) in the eight histories of science selected from three series of integrated science textbooks used in junior high school in China. Ten aspects of NOS were adopted in the analytical framework. It was found that NOS had not been well treated in the selected histories of science in the three series of science textbooks. Specifically, it was found that the empirical and inferential aspects were treated better than other aspects, and discrepancies existed among the three series of science textbooks and among the eight histories of science in terms of dealing with the target NOS aspects. Implications for addressing NOS in historical materials in science textbooks were discussed in the final part of this paper.  相似文献

This paper is a part of a longitudinal study focusing on qualitative aspects of learning in a foreign language in the development of cognitive processes in mathematics. The aim of the paper is to present a more complex analysis of textbook-based obstacles to communication. These obstacles originate in the process of vocabulary and grammar acquisition within a particular multicultural and sociocultural context. The study was carried out using mathematics textbooks from English-speaking countries which are used when teaching mathematics in English to Czech students.  相似文献

The purpose of this article is to focus on the development and refinement of a science instructional design program arguing for the feasibility and usability of integrated reading and science instruction as implemented in third‐ and fourth‐grade science classrooms to meet the learning needs of diverse learners. These instructional components are easily inserted into existing programs that build students' science background knowledge and abilities to apply learning through scaffolded activities focused on (1) providing structured opportunities for students to engage in hands‐on activities; (2) increasing vocabulary knowledge and understanding of concept‐laden terms, and (3) reading paired narrative and informational science texts. Extensive research shows that as students transition from third to fourth grade and beyond, they are often challenged in science by new vocabulary coupled with new concepts. Active ingredients of our reconceptualized science instructional design program are narrative informational texts, hands‐on science activities, and science textbook(s).  相似文献

This paper presents a qualitative study on how students make use of their mathematics textbooks for practicing. The study was carried out in two German secondary schools with 74 students (44 in 6th and 30 in 12th grade). Students’ utilization of textbooks for practicing is analyzed using the theoretical framework of instrumental genesis. The results indicate that students’ choices of contents from the book for practicing can be categorized into three utilization schemes: position-dependent practicing, block-dependent practicing, and salience-dependent practicing. In terms of position-dependent practicing the relative position of the textbook’s contents to teacher-mediated sections guides the students’ choice. Block-dependent practicing relates to the use of contents from the book that belong to particular blocks. Finally, salience-dependent practicing is a utilization scheme of the book where students’ choice is guided by perceptual salience of the book contents. These findings both show how textbook users are influenced by the way mathematics is presented in textbooks and provide insights into students’ conceptions of practicing mathematics.  相似文献

The present study examined specific science-related attitudes, informal science-related experiences, future interest in science, and gender of young high-ability students. The sample consisted of 111 high-ability students between the ages of 9 and 13. Students completed the Test of Science Related Attitudes (TOSRA), the Science Experience Survey, and the Course Selection Sheet. Two regression models were developed to predict number of physical science and life science courses selected. In the first model, gender, TOSRA subscale Career Interest in Science, and informal physical science related experience predicted 42% of the variance related to number of physical science courses selected. The second model (R2= .24) predicted number of life science courses based on informal life science related experience, informal physical science related experience, and TOSRA subscale Enjoyment of Science Lessons. Recommendations were made recognizing differences regarding gender and ability level.  相似文献

State and national initiatives attempt to increase the quantity and quality of secondary mathematics and science teachers. Research suggests that if one could appeal to something inside of people or about the process of teaching and learning itself, then one might draw current mathematics and science graduate students into secondary teaching. This study placed eight mathematics and science graduate students in secondary schools for ten hours a week. Pre‐ and post‐measures of their interest level in becoming secondary teachers were made. Overall, graduate students decreased in their desire to become secondary teachers. The main reasons were (1) fellows wanted to work with higher‐level mathematics and science; (2) fellows felt students were not behaved and unmotivated; (3) fellows did not view being a teacher as a career, but only as a job; and (4) fellows felt school systems had to do too many things that fellows did not want to do.  相似文献

Most science departments offer compulsory mathematics courses to their students with the expectation that students can apply their experience from the mathematics courses to other fields of study, including science. The current study first aims to investigate the views of pre-service science teachers of science-teaching preparation degrees and their expectations regarding the difficulty level of mathematics courses in science-teaching education programmes. Second, the study investigates changes and the reasons behind the changes in their interest regarding mathematics after completing these courses. Third, the current study seeks to reveal undergraduate science teachers’ opinions regarding the contribution of undergraduate mathematics courses to their professional development. Being qualitative in nature, this study was a case study. According to the results, almost all of the students considered that undergraduate mathematics courses were ‘difficult’ because of the complex and intensive content of the courses and their poor background mathematical knowledge. Moreover, the majority of science undergraduates mentioned that mathematics would contribute to their professional development as a science teacher. On the other hand, they declared a negative change in their attitude towards mathematics after completing the mathematics courses due to continuous failure at mathematics and their teachers’ lack of knowledge in terms of teaching mathematics.  相似文献

Elementary school goals for instruction focus on developing literate readers and writers. It has been recommended that language arts strategies can help elementary teachers more effectively teach science. The terms “integrated, interdisciplinary, and thematic instruction” are defined and examples are given for using each in an elementary classroom. Definitions are provided comparing language arts and scientific literacy. Use of thematic instruction with an interdisciplinary focus is recommended to help meet both language arts and science goals and objectives as they relate to the National Science Education Standards and the National English Language Arts Standards. Recommendations are made for helping teachers effectively use language arts strategies to help develop science literacy, and science to provide purpose for reading and writing activities within thematic, interdisciplinary instruction often found in elementary schools.  相似文献

This study explored if a weeklong science camp changed Louisiana African‐American high school students' perception of science. A semi‐structured survey was used before and after the camp to determine the changes in science attitudes and career choices. Among the perceived benefits were parental involvement, increased science academic ability, and deepened scientific knowledge. These perceived benefits influenced the identities that students constructed for themselves in relation to science in their lives. Students who reported doing well in school science courses believed that science was more relevant to their lives. Female students who cited doing well in science reported less parental involvement in their schoolwork than males. This study draws attention to gender differences in science and to designing informal science learning experiences for African‐American high school students that can change attitudes toward career choices in science‐related fields.  相似文献

This study reports on a multiyear effort to create and evaluate cognitive‐based curricular materials for secondary school science classrooms. A team of secondary teachers, educational researchers, and academic biomedical engineers developed a series of curriculum units that are based in biomedical engineering for secondary level students in physics and advanced biology classes. These units made use of an instructional design based upon recent cognitive science research called the Legacy Cycle. Over a 3‐year period, comparison of student knowledge on written questions related to central concepts in physics and/or biology generally favored students who had worked with the experimental materials over students in control classrooms. In addition, experimental students were better able to solve applications type problems, as well as unit‐specific near transfer problems.  相似文献

In an effort to maintain the global competitiveness of the United States, ensuring a strong Science, Technology, Engineering and Mathematics (STEM) workforce is essential. The purpose of this study was to identify high school courses that serve as predictors of success in college level gatekeeper courses, which in turn led to the successful completion of STEM degrees. Using a purposive sample of 893 students who had declared a STEM major between the fall of 2006 and the spring of 2008, data were collected on students' high school grades, college grades, national test scores, grade point average, gender, and ethnicity. Using analysis of variance, correlations, multiple discriminant function analysis, and multiple regression models we found that high school calculus, physics, and chemistry (respectively) were predictors of success in STEM gatekeeper college courses. Then using those courses, we constructed a predictive model of STEM degree completion. The implications of this study highlight and reinforce the importance of providing rigorous mathematics and science courses at the high school level, as well as provide some evidence of a potential mediated model of the relationship between high school performance, college performance, and graduating with a STEM degree.  相似文献

This study examined prospective elementary education majors' science teaching self‐efficacy while they were enrolled in an introductory geology lab course for elementary education majors. The Science Teaching Efficacy Belief Instrument Form B (STEBI‐B) was administered during the first and last lab class sessions. Additionally, students were asked an open‐ended question to describe their experience in the education majors' geology lab. The results of the STEBI‐B were analyzed using paired t‐tests to determine whether the students changed their personal science teaching efficacy (PSTE) and science teaching outcome expectancy (STOE). Results of this study indicate a significant increase in PSTE. No significant differences were found in STOE. This study suggests that science content courses designed for education majors may lead to a positive change in science teaching self‐efficacy and has implications for teacher educators in preparing science content courses for their teacher preparation program.  相似文献

Two sections of middle school science were taught by two longtime teachers where one used an STS approach and the other followed the more typical textbook approach closely. Pre‐ and post assessments were administered to one section of students for each teacher. The testing focused on student concept mastery, general science achievement, concept applications, use of concepts in new situations, and attitudes toward science. Videotapes of classroom actions were recorded and analyzed to determine the level of the use of STS teaching strategies in the two sections. Information was also be collected that gave evidence of and noted changes in student creativity and the continuation of student learning and the use of it beyond the classroom. Major findings indicate that students experiencing the STS format where constructivist teaching practices were used to (a) learn basic concepts as well as students who studied them directly from the textbook, (b) achieve as much in terms of general concept mastery as students who studied almost exclusively by using a textbook closely, (c) apply science concepts in new situations better than students who studied science in a more traditional way, (d) develop more positive attitudes about science, (e) exhibit creativity skills more often and more uniquely, and (f) learn and use science at home and in the community more than did students in the textbook dominated classroom.  相似文献

Student initiatives play an important role in inquiry‐based science with all students, including English language learning (ELL) students. This study examined initiatives that elementary students made as they participated in an intervention to promote science learning and English language development over a three‐year period. In addition, the study examined whether student initiatives were related to other domains of classroom practices. The study involved 70 third‐, fourth‐, and fifth‐grade classrooms with ELL students in six urban elementary schools. Results indicated that students generally made few, low‐quality initiatives. Student initiatives were generally not related to the other domains of classroom practices for grades 3 and 4, whereas initiatives were significantly related to almost all the other domains for grade 5. These results contribute to the knowledge base for fostering ELL students' initiatives in science classrooms.  相似文献

With recent national calls for the reform of science education have come standards that delineate not only science content but also assessment, pedagogy, and teachers’ professional development. If teachers must teach science differently, then teacher preparation must change. This study asked 31 inservice secondary science teachers to complete a survey about topics for inclusion in a secondary science methods course. Respondents ranked a list of prespecified topics and had an opportunity to suggest other topics for inclusion in the course. Results showed that the majority of prespecified potential topics were judged important enough by these teachers to warrant inclusion in a methods course, though no individual added topic appeared on more than two surveys. Results demonstrate that these teachers believe teaching many of the traditional topics in science methods courses is still needed. In addition, they advocated the inclusion of several topics that either represent recent technological and theoretical advances, or longstanding ideas that have recently received considerable attention.  相似文献

The purpose of the study was to examine the effectiveness of the Iowa Chautauqua Professional Development Program in terms of changes in concept mastery, use of process skills, application of science concept and skills, student attitudes toward science, student creativity, and student perceptions regarding their science classrooms. Participants were 12 teachers who agreed to participate in an experimental study where an inquiry approach was utilized with one section and traditional strategies in another section. A total of 24 sections of students were enrolled in inquiry sections (365 students) and traditional sections (359 students). The data collected were analyzed using quantitative methods. The results are tabulated and contrasted for students enrolled in the two sections for each teacher. The results indicate that student use and understanding of science skills and concepts in the inquiry sections increased significantly more than they did for students enrolled in typical sections in terms of process skills, creativity skills, ability to apply science concepts, and the development of more positive attitudes.  相似文献

Using the US national sample from the 1995 Third International Mathematics and Science Study (TIMSS), this study examined students' competence levels in understanding the matter concept at grades 3, 4, 7, 8 and high school graduation, and compared them to the expectations in the US national science education standards. It was found that third‐grade students were developing understanding on mixtures, and fourth‐grade students were developing understanding on separating mixtures; seventh‐ and eighth‐grade students were only at the beginning level of differentiating chemical properties from physical properties; they were not ready for the particulate model of chemical change. High school physical science specialization students were still at the developing level of understanding kinetic and atomic models of chemical and physical changes; they may not be able to master those theories. The findings suggest that the Benchmarks for Science Literacy and Atlas for Science Literacy may have overestimated the competences of elementary, middle school, and high school students.  相似文献

In the 19th century the textbook dominated the curriculum and methods of instruction. The most important textbook was the textbook of reading known as the reader. In the early 1800s science was not established as a separate primary grade subject. The science students encountered in these reading textbooks may have been their only formal science education. This study used content analysis to determine the type of science and the quantity of science in popular U.S. readers of the 19th century. The percent of science rose in the middle of the century and declined at the end. This decline may have been due to the desire to make the study of reading literary based. The percentage of science that was biological increased throughout the century, and the percentage of Earth science declined.  相似文献
