This paper presents findings from a 4-year project that developed and implemented a blended inquiry science and English Language Development (ELD) program in a large urban California school district. The sample included over 2,000 students in Kindergarten through 5th grade. Participating students’ English and science achievement was compared to a similar group of students who were using the district’s established English language development curriculum. Student performance on statemandated English and science assessments were analyzed using Mann–Whitney U tests for overall performance and by number of years of treatment. Modest but statistically significant improvement was found for students who participated in the blended program. Results from this study suggest that restricting instructional minutes for science to provide additional time for ELD and English language arts may be unnecessary. Rather, allowing consistent time for science instruction that incorporates ELD instruction along with inquiry science experiences may provide the authentic and purposeful context students need to develop new language without restricting access to science content. 相似文献

Student evaluations of teaching are widely adopted across academic institutions, but there are many underlying trends and biases that can influence their interpretation. Publicly accessible web-based student evaluations of teaching are of particular relevance, due to their widespread use by students in the course selection process and the quantity of data available for analysis. In this study, data from the most popular of these websites, RateMyProfessors.com, is analysed for correlations between measures of instruction quality, easiness, physical attractiveness, discipline and gender. This study of 7,882,980 RateMyProfessors ratings (from 190,006 US professors with at least 20 student ratings) provides further insight into student perceptions of academic instruction and possible variables in student evaluations. Positive correlations were observed between ratings of instruction quality and easiness, as well as between instruction quality and attractiveness. On average, professors in science and engineering disciplines have lower ratings than in the humanities and arts. When looking at RateMyProfessors as a whole, the effect of a professor’s gender on rating criteria is small but statistically significant. When analysing the data as a function of discipline, however, the effects of gender are significantly more pronounced, albeit more complex. The potential implications are discussed. 相似文献

New instructional procedures have been developed and applied at the University of Helsinki, Department of Psychology since 1986. The aim of these procedures has been to enhance effective study skills. The idea is to stimulate active learning in students by so called activating instruction, which is theoretically based on a combination of Vygotsky’s ideas, applied cognitive science, and process-oriented instruction. In many courses, students have been able to choose a preferred form of instruction among the new and the traditional methods. A six-year longitudinal study was conducted in order to see, what kinds of choices psychology students (N=114) made and how these choices were connected with their academic progress. On the basis of student’s evaluations, the new methods differed significantly from traditional methods. Students associated the development of study skills and understanding more often with activating instruction than with traditional courses. The number of activating courses taken was related to success in final exam and thesis writing. Those who participated in activating instruction studied slower during the first three years of their studying, but were more successful in the long term. 相似文献

ABSTRACT: Despite the well-documented advantages of switching to instruction based on assessment of learning outcomes, many academic disciplines, including food science, are still based on the traditional mode of instruction. The problems of converting from traditional to assessment-driven instruction are numerous and change in the university setting is slow. However, certain guidelines can be followed to start the process for change and evaluate the effects on student learning. A partnership between the industry being served and academic instructors is needed to ensure that assessment-based instruction is focused on the proper principles. Methods of assessment of learning outcomes need to be carefully chosen and developed to bring industry standards and student learning together. This can be done only if both direct and indirect assessments at the program level provide faculty with means to answer their most pressing questions about what students know and are able to do as a result of Food Science education. 相似文献

Student’s performance in science classrooms has continued to languish throughout the USA. Even though proficiency rates on national tests such as National Assessment of Educational Progress are higher for Caucasian students than African-Americans and Hispanics, all groups lack achieving desired proficiency rates. Further, the Next Generation Science Standards detail a new higher benchmark for all students. This study analyzes a professional development (PD) project, entitled Inquiry in Motion, designed to (a) facilitate teacher transformation toward greater quantity and quality of inquiry-based instruction, (b) improve student achievement in science practices and science concepts, and (c) begin to narrow the achievement gap among various groups. This 5-year PD study included 11 schools, 74 middle school teachers, and 9,981 students from diverse, high minority populations. Findings from the quasi-experimental study show statistically significant gains for all student groups (aggregate, males, females, Caucasians, African-Americans, and Hispanics) on all three science Measure of Academic Progress tests (composite, science practices, and science concepts) when compared to students of non-participating teachers. In addition to an increase in overall performance for all groups, a narrowing of the achievement gap of minority students relative to Caucasian students was seen. When combined with other studies, this study affirms that, when facilitated effectively, inquiry-based instruction may benefit all students, for all demographic groups measured. 相似文献

The purpose of this study was to examine how Korean science and engineering students view English-medium instruction (EMI) and Korean-medium instruction (KMI). The participants were 174 undergraduate students enrolled in EMI and KMI classes offered by the same instructor at a Korean science and engineering school. Interviews and questionnaire surveys were conducted, and students’ course evaluations, English scores and course grades were compared. The results of a campus-wide undergraduate student survey on EMI were also analyzed. The findings of the study show that the KMI-class students demonstrated higher levels of satisfaction and better performance in their classes than the EMI-class students did. Only 22% of the students in both classes found EMI classes helpful for improving their English ability. Nevertheless, the majority of the students supported the school’s maintenance of an EMI policy. In the conclusion, the paradoxical attitude of the students and the implications of the study are discussed. 相似文献

Scientific inquiry activities are considered as productive science instruction to improve students’ science learning and achievement. Supportive teacher-student relationships and positive disciplinary climate in the classroom are also two important factors that could facilitate student learning. This study investigates whether the association between the inquiry-based science activities and student science achievement varies by teacher support and disciplinary climate in science classrooms, particularly when taking into consideration of student gender difference and socioeconomic status (SES). This study performed regression analyses using Beijing, Shanghai, Jiangsu, and Guangdong (B-S-J-G-China) students’ science performance and background survey data of 2015 Program for International Student Assessment (PISA). Results showed that disciplinary climate, rather than teacher support, could moderate the association between inquiry-based science activities and student science achievement for both genders. Implications for instruction and further research were discussed as well. 相似文献

The study investigated the relative effectiveness of two rule-governed approaches to teaching children how to control variables. In the elaborative-rules treatment students were given a mnemonic to stimulate recall of three elements of a well-designed experiment: causes, effects, and controls. In the organized-rules treatment students were given a well-organized set of six rules that provided detailed direction with respect to the same three elements of an experiment. Intact classes of grade-5 students ( n = 283 students) were randomly assigned to two treatments and a control condition consisting of existing teacher practice; after four weeks control-group classes were reassigned to the rules treatments. Student achievement was observed prior to the implementation of conditions, after instruction, and three months later. Both rules treatment outperformed traditional instruction. The organized-rules method was slightly more effective overall, but the elaborative-rules approach had a slightly greater benefit for two groups which tend to be disadvantaged in science achievement: females and field-dependent students. 相似文献

This study investigated the hypothesis that prompting students to self-assess their interest and understanding of science concepts and activities would increase their motivation in science classes. Students were randomly assigned to an experimental condition that wrote self-assessments of their competence and interest in science lessons or a control condition that wrote summaries of those same lessons. Writing activities were 10?min long and were given approximately once a week for eighteen weeks. Student motivation was assessed via self-report surveys for achievement goals and interest in science before and after the intervention. Students in the experimental condition showed higher endorsement of mastery goals and reported greater situational interest in science topics after the intervention compared to students who summarised the lessons. Increases in situational interest predicted higher individual interest in the domain. Results indicate an instructional practice requiring just 3?hours out of a semester of instruction was sufficient to achieve these effects on motivation in science classes. 相似文献

Student evaluation of instruction in college and university courses has been a routine and mandatory part of undergraduate and graduate education for some time. A major shortcoming of the process is that it often relies exclusively on the opinions or qualitative judgments of students rather than the learning or transfer of knowledge that takes place in the classroom. To develop a more objective system of assessment, this research focused on a learning-centered approach to course work and teaching evaluation. Standardized testing tools were developed suitable for measuring the content knowledge of students in a representative group of undergraduate courses. Course evaluations were conducted using two systems of assessment: the traditional student questionnaire feedback system and one based on the learning-centered approach using a computer-based question bank and on-line testing. Significant performance differences were evident in pretest/posttest comparisons of student learning. Favorable ratings of instruction are reflected in opinions on student questionnaires. No relationship was demonstrated between learning and traditional course evaluation outcomes. Our hypothesis that the learning-centered approach provides information that is not available using the traditional student feedback system was supported.Support for this research was provided in part by Grant No. P116B981224-00 from the U.S. Department of Education, Fund for the Improvement of Post-Secondary Programs awarded to the University of North Carolina at Charlotte. The opinions expressed do not necessarily reflect the position or policy of the Department of Education, and no official endorsement should be inferred. 相似文献

ABSTRACT: The purpose of this study was to ascertain whether a Web-based computer tutorial for food safety is an effective tool in the education of food science and nutrition students. Students completing the Web-based tutorial had a greater improvement in pre-test scores compared with post-test scores and compared with students who attended lecture only. Students completing the tutorial indicated a favorable attitude toward computer-supplemented instruction. 相似文献

This study follows graduate interns and their cooperating teachers through a collaborative student teaching experience in D/HH and hearing classrooms at the same grade level. Teacher teams, enrolled in a graduate course on collaboration, designed and conducted collaborative instruction (K-junior high school level), which focused on cooperative learning activities. Measures included student evaluations and separate intern and teacher evaluations of student performance, the integrated instructional units, and professional collaboration. Student evaluations included positive responses to integrated instruction by both groups, though there was more trepidation expressed by some D/HH students. Teachers reported very positive outcomes for all students including increased motivation to learn about and to interact with the other group and, for D/HH students, an increase in socially and academically appropriate behaviors. Specific student needs for training prior to integrated experiences were noted. Teachers stressed the importance of topic selections that would involve the expertise of all participants equally, needs for teacher in-service training and, administrative support for collaborative planning. 相似文献

Colleges and universities are increasingly using information technologies to enhance the learning environment. Many educational
institutions offer Internet-based on-line courses in an effort to meet the educational needs of students. The primary goal
of this research was to determine if there is a relationship between students' preferred learning environment (i.e. face-to-face
or on-line) and their learning style. The secondary goal was to determine if there were any differences in the academic success
of students in the face-to-face versus on-line sections. Participants were adult (ages 22+ years), non-traditional computer
science students given the option to take a face-to-face lecture-based or an on-line Internet-based computer science course.
Results revealed that computer science students in the face-to-face learning environment were more likely to have the Assimilator
learning-style, whereas computer science students in the on-line Internet-based learning environment were more likely to have
the Converger learning-style. Student academic success did not reliably differ as a function of learning environment selection.
Implications of these results are discussed in terms of learning style characteristics of computer science students, learning
styles and gender differences and implications of student academic success in on-line vs face-to-face environments.

Several studies have found active learning to enhance students’ motivation and attitudes. Yet, faculty indicate that students resist active learning and censure them on evaluations after incorporating active learning into their instruction, resulting in an apparent paradox. We argue that the disparity in findings across previous studies is the result of variation in the active learning instruction that was implemented. The purpose of this study was to illuminate sources of motivation from and resistance to active learning that resulted from a novel, exemplary active-learning approach rooted in essential science practices and supported by science education literature. This approach was enacted over the course of 4 weeks in eight sections of an introductory undergraduate biology laboratory course. A plant concept inventory, administered to students as a pre-, post-, and delayed-posttest indicated significant proximal and distal learning gains. Qualitative analysis of open-response questionnaires and interviews elucidated sources of motivation and resistance that resulted from this active-learning approach. Several participants indicated this approach enhanced interest, creativity, and motivation to prepare, and resulted in a challenging learning environment that facilitated the sharing of diverse perspectives and the development of a community of learners. Sources of resistance to active learning included participants’ unfamiliarity with essential science practices, having to struggle with uncertainty in the absence of authoritative information, and the extra effort required to actively construct knowledge as compared to learning via traditional, teacher-centered instruction. Implications for implementation, including tips for reducing student resistance to active learning, are discussed. 相似文献

The purpose of this study was to empirically investigate, in a large-scale assessment, the prevalence of enquiry-based teaching, as defined by PISA, implemented in science lessons, and the extent to which it is related to students from different socioeconomic status (SES) family backgrounds in the U.S. The Programme of International Student Assessment (PISA) 2015 data including 5,146 students in the U.S. were used. A Latent Profile Analysis (LPA) was conducted to classify students into different science teaching subgroups. Mixture regression analysis was conducted to examine whether there the association between SES and achievement varied across science teaching subgroups. Four science teaching subgroups were identified, varying in the frequency of and type of teaching practices used. Students’ attitudes, gender, science instruction time, and reading achievement are significant predictors of the subgroup membership. SES-achievement gap also varied across the science teaching subgroups. Discussions for the results and suggestions for future study were presented. 相似文献

This study utilized data from the 2006 Programme for International Student Assessment Hong Kong sample to investigate the factors that impact the science achievement of 15-year-old students. A multilevel model was used to examine the factors from both student and school perspectives. At the student level, the results indicated that male students, students from high socioeconomic status (SES) families, students with higher motivation and higher self-efficacy, and students whose parents highly value science are more likely to demonstrate achievement in science. At the school level, the results showed school science achievement differences can be explained by school enrolment size, school SES composition, and instruction time per week. Contrary to the negative influence of school size that was reported in previous studies, our findings suggested a positive relationship between school enrolment size and science achievement. This finding leads to an international discussion of school size. 相似文献

Student evaluations of instruction were obtained from two groups. Students in the first group were “reverse transfer” students (N = 97) who completed their freshman year at a university and then transferred to a two‐year college for their sophomore year. Students in the second group were “early transfer” students (N = 78) who completed their freshman year at a two‐year college and then transferred to a university. All students had one year of attendance at a two‐year college and one year at a university. The purpose of the study was to analyze the ratings of both groups of students with regard to their academic experiences at the university and at the two‐year college. An adaptation of the Student Instructional Report (SIR) was used to obtain ratings on overall college experiences from all students at the end of their sophomore year. The findings revealed: (1) considerable similarity of ratings given to the two‐year college and the university, (2) differences between ratings of early transfer and reverse transfer students, and (3) generally high ratings for both the two‐year college and the university. 相似文献

The purpose of this study was to compare the opinions of students, teachers, and administrators relative to student evaluation of instruction in selected community colleges. While important educational decisions in community colleges are made on the basis of students’ evaluations (as in retention, promotion, tenure, and pay), little has been accomplished in testing the assumptions behind student evaluation of instruction. The student evaluation process assumes that students are honest, serious, and evaluate instruction, not some incidental activity. A 25‐item Student Evaluation Process Scale was completed by 607 students, 130 faculty, and 45 administrators in five Illinois community colleges. Findings revealed little significant differences in the opinions of students regarding evaluation of instruction based on variables of sex, age, school location, student type (transfer or occupational), and class standing. There were little significant differences in faculty opinion and within the administrative groups based on selected variables. There were significant differences when the opinions of students, faculty, and administrators were compared. Students and faculty tended to agree with those items that questioned the objectivity of student evaluation of instruction. Administrators and students tended to agree with items reflecting the seriousness with which students evaluate instruction. Faculty and administrators indicated that student evaluation of instruction impacted faculty members’ instructional performances. Neither students, faculty, nor administrators supported the concept of merit pay tied to student evaluation of instruction. The role of student evaluation of instruction in a faculty evaluation system must be investigated. A variety of groups should participate in this investigation. 相似文献

Historically, high school chemistry has been the predominate venue for the introduction of food science curriculum to students. With the current decline in chemistry as a required course for graduation, the possibility of exposure to food science in high school could equally decline. The purpose of this research was to determine if high school students in a biology class without a chemistry background could comprehend eight basic food science principles equally as well as students in a chemistry class that were taught the same principles. This study assessed baseline knowledge of high school students, determined the effect of food science‐based lessons on baseline knowledge and level of understanding, and determined the effect of food science‐based lessons on students’ awareness of and interest in food science. Baseline knowledge and awareness of food science was low. Food science‐based instruction resulted in higher posttest scores. Results indicated no differences in students’ knowledge base and level of understanding between biology and chemistry classes and supported the idea of further incorporating a food science curriculum into high school biology. 相似文献
