In recent educational literature, it has been observed that improving student's control has the potential of increasing his or her feeling of ownership, personal agency and activeness as means to maximize his or her educational achievement. While the main conceived goal for personal learning environments (PLEs) is to increase student's control by taking advantage of Web 2.0 tools and technologies, there is not a robust learning model available to achieve it. This contribution focuses on proposing a learning model built upon self‐regulated learning and student's control theories and concepts, and supported by the learning affordances of Web 2.0 tools and technologies for enhancing student's control by developing and applying Web 2.0 PLEs. 相似文献

Changes in the cultural and linguistic environments of learners are often associated with identity shifts. The aim of this study was to explore what identity shifts occur when science students from Bahraini national schools transition to an international university. The role of two aspects of learner identity—that is, English proficiency and science background knowledge, was examined in this study. Focus groups and semi-structured interviews were conducted with students and with university lecturers. The analysis suggested three conceptual themes of (1) reliance on science knowledge, (2) the auxiliary role of professional language and (3) adequacy of student learning strategies, demonstrating what subjective meanings the participants ascribe to the interplay between science knowledge and linguistic ability. The findings suggest that despite the lack of adequate linguistic attributes, the students are still able to successfully learn science in the context of language change. It is also implied that through strategically utilising their academic background in science, students preserve their identity as successful learners from school through to university. We conclude that agency plays a separate role in transition and is not a sole function of identity. We also contest the idea of language as a necessary attribute of one’s identity as it was perceived by our participants to be an advantage and an auxiliary tool rather than a requirement. 相似文献

Breast cancer is one of the most frequent cancer types within women population. Hydroxyurea (HU) is a chemotherapy compound for treatment of patients with cancer diagnosis, including breast cancer associated with several adverse effects. In this study, we applied nanotechnology to decreased drug side effects along with improvement of therapeutic index. Liposomation is widely used in modern pharmacological developments in order to enhance the effects of the drugs. To achieve this, in this study a mixture of phosphatidylcholine and cholesterol was made up and HU was added to the resultant mixture, was then pegylated using Polyethylene Glycol 2000 to increase resistance, applicability and solubility. The mean diameters of nanoliposomal and pegylated nanoliposomal HU were measured by Zeta sizer device and obtained about 402.5 and 338.2 nm. The efficiency of non-pegylated and pegylated liposomal HU was 70.8 and 64.2, respectively. Releasing HU in both formulations was estimated about 25.8 and 21.7 %. Also, this study investigated the cytotoxicity effect of nanoliposomal and pegylated nanoliposomal HU using MTT assay. Results of this investigation showed that the cytotoxic properties of pegylated HU was 3.6 % more than those non-pegylated form, while was 38.93 % more than ordinary from of HU. This study showed that the stability, releasing pattern and cytotoxicity of the pegylated nanoliposomal HU is better than that of nanoliposomal HU. 相似文献

This paper identifies the amount of variance in mathematics achievement in high- and low-achieving schools that can be explained by school-level factors, while controlling for student-level factors. The data were obtained from 2679 Iranian eighth graders who participated in the 2007 Trends in International Mathematics and Science Study. Of the total sample, 1422 and 1257 students were from high- and low-achieving schools, respectively. Two-level hierarchical linear modelling was applied. The results indicated that of the total variance in mathematics achievement, 27.95 and 6.70% were due to between-school differences in the high- and low-achieving schools, respectively. Controlling for the school-level factors, the better-performing students were those with a higher level of confidence in learning mathematics in both samples. After controlling for the student-level factors, inadequacies in school resources and school type yielded the strongest link to achievement in the high- and low-achieving schools, respectively. 相似文献

The purpose of the study was to determine the effects of modified Proprioceptive Neuromuscular Facilitation (PNF) flexibility techniques on hip flexion in college males and to determine if local cold application enhances the effectiveness of these techniques. Male subjects (N = 120), with an average age of 21.5 +/- 2.7 years, were randomly assigned to one of four different kinds of stretching treatments with cold or no cold application (15 per group). Range of motion (ROM) in degrees was determined following four stretching techniques: three modified PNF (PCP, 3-PIECP, 3-PIFCP) and a passive stretch (P). Data were analyzed using a 2 (conditions) x 4 (treatments) ANOVA. There were no significant differences in ROM between cold and no cold conditions. Significant differences existed among ROM techniques (p less than .05). Post hoc analyses revealed that the three modified PNF techniques resulted in greater ROM than the passive stretch technique. However, we conclude that cold application does not influence the effectiveness of selected stretching techniques. 相似文献

This study compares the effects of two methods of teaching—teacher-centered and cooperative learning—on students’ science
achievement and use of social skills. The sample consists of 163 female elementary science students in 8 intact grade 5 classes
who were assigned to 2 instructional methods and were taught an identical science unit by 4 classroom teachers. The students’
science achievement was measured by a researcher-designed achievement test given to students as a pretest and a posttest.
Students’ social skills were determined by a researcher-designed survey administered as a pretest and posttest. Analysis of
the achievement test scores and the social skills survey responses revealed that cooperative learning strategies have significantly
(p > 0.05) more positive effects on both students’ achievement and social skills than teacher-centered strategies. These results
provide an evidential base to inform policy decisions and encourage and persuade teachers to implement cooperative learning
methods in Kuwaiti classrooms. 相似文献

The debate about Islam and science extends to a debate about the relationship between Islam and science education. In this
paper, I explore Egyptian teachers’ views of the relationship between science and religion within the Islamic context. Teachers’
key vision of the relationship between science and religion was that “religion comes first and science comes next. I will
argue that teachers’ personal religious beliefs are among the major constructs that drive teachers’ ways of thinking and interpretation
of scientific issues related with religion. Then, I discuss how teachers’ personal religious beliefs have been formed and
influenced their pedagogical beliefs related to science and religion issues. Finally, I will argue, how we use the personal
religious beliefs model as a framework of teaching/learning scientific issues related with religion within sociocultural (Islamic)
context.

Word recognition and basic cognitive processes among reading-disabled and normal readers in Arabic 总被引：1，自引：0，他引：1
This study investigated word identification inArabic and basic cognitive processes inreading-disabled (RD) and normal readers of thesame chronological age, and in younger normalreaders at the same reading level. The studyfocused on the word identification processes ofphonological decoding and orthographicprocessing and the cognitive processes ofsyntactic and morphological awareness, workingmemory, and visual processing. RD children werecompared with normal readers on a battery oftests developed in Arabic on the basis of thoseavailable in English and Hebrew. The presentresults revealed deficiencies among the RD childrenin phonological decoding, in contrast torelative strengths in orthographic processing. These data were consistent with English-languagefindings. The analysis of basiccognitive processes indicated significantdeficiencies in morphology, working memory, andsyntactic and visual processing, with the mostsevere deficiencies observed for phonologicalawareness. The results are discussed in lightof international RD findings and the nature ofArabic orthography. 相似文献
