ABSTRACTThis study investigates the relationship between teenagers’ use of social networking sites (SNS) and their sourcing abilities. Sourcing is defined as students’ ability (1) to discriminate reliable and unreliable links based on source characteristics, (2) to value source criteria as means to select information resources and (3) to select reliable texts based on source characteristics. One hundred and forty-six students (M age = 14.7 years old) completed three sourcing tasks, a questionnaire on SNS use, as well as language and memory skills tests. We found that SNS frequency of use negatively predicted both participants’ ability to select the most reliable source among two conflicting sources on the same topic and their ability to cite source features when justifying their choice. SNS frequency of use was unrelated to students’ assessment of source criteria, but vocabulary level was positively related to performance in this task. We discuss various explanations for the observed relationship between teenagers’ SNS communication and their critical appraisal of information sources, and we propose avenues for instructional interventions aimed at fostering information skills. 相似文献

A teaching tool that facilitates student understanding of a three‐dimensional (3D) integration of dermatomes with peripheral cutaneous nerve field distributions is described. This model is inspired by the confusion in novice learners between dermatome maps and nerve field distribution maps. This confusion leads to the misconception that these two distribution maps fully overlap, and may stem from three sources: (1) the differences in dermatome maps in anatomical textbooks, (2) the limited views in the figures of dermatome maps and cutaneous nerve field maps, hampering the acquisition of a 3D picture, and (3) the lack of figures showing both maps together. To clarify this concept, the learning process can be facilitated by transforming the 2D drawings in textbooks to a 3D hands‐on model and by merging the information from the separate maps. Commercially available models were covered with white cotton pantyhose, and borders between dermatomes were marked using the drawings from the students' required study material. Distribution maps of selected peripheral nerves were cut out from color transparencies. Both the model and the cut‐out nerve fields were then at the students' disposal during a laboratory exercise. The students were instructed to affix the transparencies in the right place according to the textbook's figures. This model facilitates integrating the spatial relationships of the two types of nerve distributions. By highlighting the spatial relationship and aiming to provoke student enthusiasm, this model follows the advantages of other low‐fidelity models.

Sex differences favoring males in spatial abilities have been known by cognitive psychologists for more than half a century. Spatial abilities have been related to three‐dimensional anatomy knowledge and the performance in technical skills. The issue of sex differences in spatial abilities has not been addressed formally in the medical field. The objective of this study was to test an a priori hypothesis of sex differences in spatial abilities in a group of medical graduates entering their residency programs over a five‐year period. A cohort of 214 medical graduates entering their specialist residency training programs was enrolled in a prospective study. Spatial abilities were measured with a redrawn Vandenberg and Kuse Mental Rotations Tests in two (MRTA) and three (MRTC) dimensions. Sex differences favoring males were identified in 131 (61.2%) female and 83 (38.8%) male medical graduates with the median (Q1, Q3) MRTA score [12 (8, 14) vs. 15 (12, 18), respectively; P < 0.0001] and MRTC score [7 (5, 9) vs. 9 (7, 12), respectively; P < 0.0001]. Sex differences in spatial abilities favoring males were demonstrated in the field of medical education, in a group of medical graduates entering their residency programs in a five‐year experiment. Caution should be exerted in applying our group finding to individuals because a particular female may have higher spatial abilities and a particular male may have lower spatial abilities.

In this article, we, a multivocal-thinking-assemblage, trouble what we feel is the dogmatic image of thought in science education. Beginning with Lars Bang’s (Cult Stud Sci Educ, 2017) dramatic and disruptive imagery of the Ouroboros as a means to challenge scientific literacy we explore the importance of dreams, thinking with both virtual and actual entities, and immanent thinking to science education scholarship. Dreaming as movement away from a dogmatic image of thought takes the authors in multiple directions as they attempt to open Deleuzian horizons of difference, immanence, and self-exploration. 相似文献

The present study explored how relationships with natural mentors may contribute to African American adolescents’ long‐term educational attainment by influencing adolescents’ racial identity and academic beliefs. This study included 541 academically at‐risk African American adolescents transitioning into adulthood. The mean age of participants at Time 1 was 17.8 (SD = .64) and slightly over half (54%) of study participants were female. Results of the current study indicated that relationships with natural mentors promoted more positive long‐term educational attainment among participants through increased private regard (a dimension of racial identity) and stronger beliefs in the importance of doing well in school for future success. Implications of these findings and directions for future research are discussed. 相似文献

This paper considers the copper electrodeposit ion processes in microvias and investigates whether the quality of the electroplating process can be improved by acoustic streaming using megasonic transducers placed into a plating cell. The theoretical results show that acoustic streaming does not take place within the micro-via (either through or blind-via' s), however it does help improve cupric ion transport in the area close to the mouth of a via. This replenishment of cupric ions at the mouth of micro-via leads to better quality filling of the micro-via through diffusion compared to basic conditions. Experiments showing the improved quality of the filling of vias are also presented. 相似文献

The purpose of this study was to identify the root metaphors of secondary classroom teachers and to observe ways in which these constructs influence teachers’ work with their students and their environments. Specifically, five case studies of novice teachers were presented. Results indicated that the metaphor of life as a tree was the most common view and that all five participants held a similar childhood metaphor in which they tended to idealize childhood. Overall, the data showed the persistence of ideas that beginning teachers bring to their university preparation and those beliefs extend into actual classroom practice. Teacher development seemed to be more influenced by the schooling environment rather than the pre‐service preparation the teachers received. Furthermore, these novice teachers felt conflict between their held beliefs and the reality of teaching and schooling. Implications for teacher educators and future research are included. 相似文献
