The aim of the study is to examine undergraduate students’ awareness of metacognition, the metacognitive strategies they use in their learning and their learning performance in pre-class asynchronous activity in a flipped classroom. The sample consisted of 47 undergraduate students. Eleven students were not included in this study since they did not participate in all quizzes and most of the metacognitive strategy activities. Metacognitive Awareness Inventory and Metacognitive Strategies Evaluation Activities were used as data collection tools. The results showed that Computer Education and Instructional Technology students’ metacognitive awareness was at a high level and their metacognitive strategy levels and learning performances differed weekly. Post hoc results indicated no difference between metacognitive strategy and learning performance in the first three weeks. However, the results of the first 3 weeks differed from those of the 4th and 5th weeks. In addition, our regression analysis result indicated that using metacognitive strategies predicted 80% of students’ learning performance. This rate shows the importance of using metacognitive strategies for the learning process in pre-class asynchronous activity in the flipped classroom. 相似文献

The effects of sunflower oil, olive oil, margarine, soybean oil and butter on cholesterol and triglyceride levels were investigated
in the brain of rats. Rats were fed with a diet containing 15% of the oils for a period of 8 weeks. The rats were then decapitated,
brain samples were removed, homogenized and cholesterol and TG levels were measured. Brain cholesterol and Triglycerides levels
of all animals receiving different oils were significantly higher according to the contol except TG level of animals receiving
margarine. Brain cholesterol levels of the vegetable oils were statistically higher than those receiving saturated oil. Thus,
cholesterol level of the rats fed with olive oil group was significantly higher than that of the other groups but those receiving
sunflower oil group and Triglycerides level of the animals receiving olive oil was significantly higher than that of the other
groups except animal supplemented with soybean oil. Thus, it is concluded that brain lipid levels of rats are differently
effected by various oils and mechanism of which needs to be investigated. 相似文献

The work presented here represents a preliminary attempt to address the role of teachers in supporting students’ learning on socio-scientific issues (SSI) by characterising pre-service biology teachers’ perceptions and adaptation of curriculum and identifying factors that serve to mediate this process. A hundred and two undergraduate pre-service biology teachers took part in this study over the course of one semester. The teacher candidates (72% female) completed a questionnaire comprising Likert-type and open-ended questions. The results indicated that the teacher candidates perceived a need to address SSI positively. Pre-service teachers had moderate personal teaching efficacy beliefs related to teaching about SSI. They also identified the lack of instructional time and the unavailability of relevant materials as the primary obstacles hindering the teaching of SSI. The implications for teacher education and the design of curriculum materials with respect to SSI are discussed. 相似文献

Science education researchers recently turned their attention to exploring views about nature of science (NOS). A large body of research indicates that both students and teachers have many naïve views about the NOS. Unfortunately, less attention has been directed at the issue of exploring the views of the scientists. Also, the little research in the literature generally took into consideration NOS views of only natural scientists. This study primarily proposes to explore the views of scientists in both the natural and social sciences regarding the seven target aspects of NOS. The second aim of the study is to find out the similarities and dissimilarities between the views of scientists who majored in social sciences and those who majored in natural sciences in terms of the target aspects of NOS. The sample was 69 scientists representing 5 scientific disciplines from natural and social sciences. Interviews were employed for obtaining data. The data were analyzed by means of cognitive maps. This study revealed that the scientists in the sample have neither completely informed views nor completely naïve views according to contemporary scientific understanding. Their views were a blend of the two in terms of almost all the target aspects of NOS. The views of the scientists in natural science and in social science were not substantially different. The scientists from both groups generally had similar viewpoints. This situation suggested that the scientists' views about NOS are not related to their scientific disciplines. 相似文献

Students use general web search engines as their primary source of research while trying to find answers to school-related questions. Although search engines are highly relevant for the general population, they may return results that are out of educational context. Another rising trend; social community question answering websites are the second choice for students who try to get answers from other peers online. We attempt discovering possible improvements in educational search by leveraging both of these information sources. For this purpose, we first implement a classifier for educational questions. This classifier is built by an ensemble method that employs several regular learning algorithms and retrieval based approaches that utilize external resources. We also build a query expander to facilitate classification. We further improve the classification using search engine results and obtain 83.5% accuracy. Although our work is entirely based on the Turkish language, the features could easily be mapped to other languages as well. In order to find out whether search engine ranking can be improved in the education domain using the classification model, we collect and label a set of query results retrieved from a general web search engine. We propose five ad-hoc methods to improve search ranking based on the idea that the query-document category relation is an indicator of relevance. We evaluate these methods for overall performance, varying query length and based on factoid and non-factoid queries. We show that some of the methods significantly improve the rankings in the education domain. 相似文献

Previous studies have compared student performance for the same or similar classes delivered both online and face-to-face. However, few studies have explored the role that a change in learning environment plays in the student’s ability to transfer skills and knowledge gained in prerequisite courses to follow-on, or post-requisite, courses. The purpose of this study was to examine the relationship between student demographic factors, learning environments, and the transfer of skills and knowledge in undergraduate accounting education. In addition, this study examined student perceptions of online learning both before and after the course learning sequence, and the specific accommodations instructors made to their instructional design to facilitate the delivery medium change in learning environment. Data for this study was collected from 2,324 students and their corresponding instructors participating in a sequence of two undergraduate accounting courses at a large Midwestern U.S. university. Results revealed a positive relationship between a student’s performance in post-requisite coursework and GPA, the number of completed credits, and enrollment status (full or part-time). Instructors made delivery medium specific adjustments in course topic coverage, student participation, and group work to accommodate for the perceived capabilities of the learning environment. 相似文献

This study was conducted in order to identify the intensity of Turkish students’ views with regard to environmental issues presented in the national curriculum and to determine how these views differ by gender, grade level, previous science achievement, socio‐economic status (SES), and school location. For this project, a 51‐item Attitude Toward Environmental Issues Scale (ATEIS) was created and utilized. In total, the scale involved 30 distinct environmental issues. These environmental issues are emphasized in the current Turkish science education curriculum. A total of 458 students in grade 4–8 classrooms completed the scale. Rasch analysis results indicated that, in general, the students felt environmental problems should be confronted in Turkey. But when students were presented with a range of survey items stating that a particular environmental issue should take precedence over economic growth, it was often very difficult for students to agree. On the other hand, when students were simply presented a range of survey issues concerning environmental problems in Turkey, it was easy for them to agree with the presence (or importance) of these environmental issues in Turkey. Subsequent analysis suggested that the set of ATEIS survey items were understood and functioned in a similar measurement manner for male and female students, as well as elementary and middle school students. Results of ANOVA analyses indicated that recent high achievement in science courses resulted in more positive attitudes toward environmental issues. T‐test analyses revealed that the older female students of this data set exhibited more support for environmental issues than did male students. Students with high family income, and those students living in urban areas, displayed more positive attitudes toward environmental issues than did students with low family income, and those living in suburban areas. 相似文献
