The aim of this study was to compare the achievement of prospective primary science teachers in a problem-based curriculum
with those in a conventional primary science teacher preparation program with regard to success in learning about gases and
developing positive attitudes towards chemistry. The subjects of the study were 101 first year undergraduate students, who
were in two different classes and who were taught by the same lecturer. One of the classes was randomly selected as the intervention
group in which problem-based learning (PBL) was used, and the other as the control in which conventional teaching methods
were used. The data were obtained through use of the gases diagnostic test (GDT), the chemistry attitude scale (CAS), and
scales specific to students’ evaluation of PBL such as the peer evaluation scale (PES), self evaluation scale (SES), tutor’s
performance evaluation scale (TPES) and students’ evaluation of PBL scale (SEPBLS). Data were analysed using SPSS 10.0 (Statistical
Package for Social Sciences). In order to find out the effect of the intervention (PBL) on students’ learning of gases, independent
sample t-tests and ANCOVA (analysis of co-variance) were used. The results obtained from the study showed that there was a statistically
significant difference between the experimental and control groups in terms of students’ GDT total mean scores and, their
attitude towards chemistry, as well as PBL has a significant effect on the development of students’ skills such as self-directed
learning, cooperative learning and critical thinking. 相似文献

This study aimed to evaluate the Pre-service Teachers’ (PSTs’) field experience-related perceptions and the qualities of their written reflections. Two thousand four hundred journal entries written by 75 teacher candidates were analyzed to classify their qualities. In addition, semi-structured interviews were conducted with all of the subjects. The results showed that the largest proportion of the written entries was classified as technical. Only a small percentage of the subjects reached the highest level of reflection called as transformative. During the field experiences, the PSTs had mainly self, cooperating teachers, and student-related issues and perceptions. At the end of the field experiences, they recommended to start the practicum courses from the first year of the faculty and to increase the weekly hours of these courses. It is important to note that the PSTs need additional knowledge and practices about the reflection, reflective writing, and the qualities of reflection. 相似文献

Experimental studies on the head fake in basketball showed that participant’s responses in a pass direction identification task were delayed for incongruent compared to congruent directions of the players gaze and pass (so-called head fake effect). In these studies on the head fake effect, static pictures were presented and responses on the pass direction were given with a simple key press. The present study examines whether an increase in the response complexity affects the head fake effect and whether it can also be transferred to the presentation of dynamic stimuli. In experiment 1, participants were presented with static pictures of a basketball player who passes a ball to the left or to the right. The player’s gaze direction was either oriented in the direction of the intended pass or in the opposite direction (i.?e., a head fake). The participants were asked to respond as quickly as possible to the pass direction and to ignore the gaze direction. Participants gave responses by pressing a key (simple response) or by executing a quasirealistic defense movement (complex response). Response complexity was blocked. In experiment 2, videos replaced the static stimuli. The responses were only given with the complex, full body movement. Results show that the head fake effect is independent of response complexity and that it can also be found when presenting dynamic stimuli. 相似文献

Advancements in digital technology are making waves in the publishing industry and e-publishing is starting to make its mark in the market. Although publishers view e-publishing as an opportunity to exploit products and new distribution channels, some of them are seeing this development as a risk rather than an opportunity, and thus are not willing to participate in these changes. This study was conducted to determine the readiness of e-publishing among Malaysian book publishers based on the E-Publishing Readiness Assessment Model. The results found that publishers in Malaysia are prepared in terms of infrastructure and human resources. However, only a small percentage of them are willing to practice e-publishing by publishing at least one e-book, while the majority is taking a wait and see approach before they start issuing e-books. Interviews with two companies displaying high levels of e-readiness and low e-readiness, showed a willingness depend on the decision of the company’s top management. In addition, external factors such as market demand, technological pressure, competition, consumer habits and police and government policies also affect the results of the top management to run e-publishing in their respective companies. Through these findings, the government and agencies involved in the publishing industry may be able to help find a solution when designing a strategy for improving e-publishing practices in Malaysia. 相似文献

The purpose of the current study is to explicitly test the extent to which issue contexts affect the informal reasoning processes engaged in by individuals. In order to address the research question framing this study, we engaged 39 Turkish preservice science teachers (PSTs) in interviews designed to elicit argumentation related to multiple socioscientific scenarios. Three scenarios related to gene therapy, another three related to human cloning, and the final scenario related to global warming. The data were analyzed using an interpretive qualitative research approach. Our work builds on a framework initially proposed by Toulmin in 1958. This study has provided new evidence related to informal reasoning in the context of socioscientific issues (SSI). At the sample level, there was strong consistency in informal reasoning quality among varying socioscientific scenarios. However, finer‐grained analyses indicated a greater level of variability in the informal reasoning practices of individual PSTs. These results support previous conclusions that suggest context dependence for informal reasoning related to SSI. This study provides an initial picture of the reasoning practices of preservice teachers as opposed to science learners. The results indicate that teachers, at least those in this Turkish setting, would benefit from learning experiences that support their own informal reasoning practices as well as their ability to foster development of these practices among their students. We encourage the field to continue the investigation of SSI as contexts for education particularly as it relates to the education of teachers. 相似文献

This study examined pre-service mathematics teachers’ knowledge of history of mathematics and their attitudes and beliefs towards using history of mathematics in mathematics education based on year level in teacher education program and gender. The sample included 1,593 freshman, sophomore, junior, and senior pre-service middle school (grades 4–8) mathematics teachers from nine universities in Turkey. Data were collected through Knowledge of History of Mathematics Test and Attitudes and Beliefs towards the Use of History of Mathematics in Mathematics Education Questionnaire. Results indicate that pre-service teachers have moderate knowledge of history of mathematics and positive attitudes and beliefs towards using history of mathematics. Their knowledge scores increase as the year level in teacher education program advanced. Males’ knowledge scores are significantly higher than females’ scores in the first 2 years. This situation reverses in the last 2 years, but it is not statistically significant. Pre-service teachers have more positive attitudes and availing beliefs towards using history of mathematics as they progress in their teacher education program. Females have greater attitudes and beliefs mean scores than males in each of the years. The results indicate that the teacher education program may have enhanced the pre-service teachers’ knowledge of history of mathematics by related courses. However, the moderate knowledge scores indicate that there is a need for revision of these courses. The pre-service teachers’ positive attitudes and beliefs towards using history of mathematics stress the importance of teacher education program in order to prepare them for implementing this alternative strategy in the future. 相似文献

Knowledge is regarded as a strategic resource in organizations; thus the leverage of knowledge is a key managerial issue. Knowledge creation, sharing and dissemination are the main activities in knowledge management. This study examines the influence that social and technological factors, such as learning culture and IT use, could have on knowledge sharing among students of the King Fahd University of Petroleum and Minerals in Saudi Arabia. A cross-sectional survey was used as a research method for data collection and 302 valid responses were collected from all the three categories of students that include graduates, undergraduates and preparatory students. The results show that there is a significant positive relationship between both student learning culture and IT use and students’ knowledge sharing. The limitations of this study and practical implications, along with directions for further research are discussed. 相似文献

While debate about the use of—and alternatives to—human cadaveric dissection in medical training is robust, little attention has been paid to questions about timing. This study explores the perspectives of medical students and recent graduates with regard to two key questions: when in the degree program do students prefer dissection opportunities and what are the students getting out of participating in dissection? Self-report survey data from students in preclinical years (n = 105), clinical years (n = 57), and graduates (n = 13) were analyzed. Most (89%) preferred dissection during the preclinical years, with no effect by training year (χ2 = 1.98, p = 0.16), previous anatomy (χ2 = 3.64, p = 0.31), or dissection (χ2 = 3.84, p = 0.26) experience. Three key findings emerged. First, the majority of students prefer to dissect in the preclinical years because they view dissection as important for developing foundation knowledge and delivering an opportunity for consolidation prior to transitioning to primarily clinical studies. In addition, students recognize that it is a time-consuming activity requiring specialized facilities. Second, three main understandings of the purpose of dissection were reported: depth of learning, learning experience, and real-world equivalence. Third, these student perspectives of the purpose of dissection are associated with timing preferences for dissection opportunities. The results identify the preclinical phase as the optimal time to strategically integrate dissection into medical training in order to maximize the benefits of this unique learning opportunity for students and minimize its impact upon curricular time. 相似文献
