Evidence regarding the effect of early reading instruction on later reading achievement is unusually sparse, given the emphasis often placed on early and intensive reading instruction. Capitalising on international differences in school entry age (SEA), international reading studies may provide such evidence; however, only one quantitative analysis has been conducted that looked at nine-year olds over 17 years ago. Therefore, data from the reading portion of the 2006 Programme for International Student Assessment (PISA) study were re-analysed. The relative reading achievement—as a function of SEA—of 15-year-old students across 55 countries was investigated, controlling for social and economic differences. Results suggested no significant association between reading achievement and SEA. Theoretical explanations for these findings are discussed. 相似文献

Assessing the impact of the Graduate Certificate in Anatomical Sciences Instruction: A post‐degree survey 下载免费PDF全文
April Richardson‐Hatcher Brian MacPherson Douglas Gould Jennifer Brueckner‐Collins 《Anatomical sciences education》2018,11(5):516-524
There are few graduate programs available for pursuing a doctorate in anatomy where students gain specific training in gross anatomy dissection and the responsibilities of a medical educator. In light of this fact, the University of Kentucky created a Graduate Certificate in Anatomical Sciences Instruction in 2006. This 12‐credit hour curriculum includes detailed training in gross anatomy and/or neuroscience courses, practicum experiences, a seminar class in pedagogical literature, and a course in educational strategies for the anatomical sciences. The award of certificate completion affirms that the candidate has demonstrated faculty‐supervised proficiency in anatomy dissection, instruction in anatomy topics, and teaching strategies for anatomy. Seventeen graduate students have earned the certificate since its inception; nine students accepted teaching positions in anatomy following their graduate training and currently nine certificate graduates have assistant (six) or associate (three) professor positions in academia. In 2016, an anonymous survey including Likert‐style and open‐ended questions was emailed to all certificate graduates. Graduates favorably responded (each question averaged 4.4 or greater out of 5) that the certificate increased their awareness of teaching‐faculty responsibilities, adequately prepared them for teaching‐related duties, and positively contributed toward their first employment. Graduates indicated that the lecturing and dissection experience, awareness of faculty responsibilities, and job preparation (e.g., teaching philosophy development) were the most helpful aspects of the certificate. These results indicate that the Graduate Certificate in Anatomical Sciences Instruction is viewed by its graduates and their employers as a valuable teaching credential that can be attained alongside a basic science degree.

In diesem Artikel wird MINERVA pr?sentiert, eine prototypische Implementierung einer verteilten Suchmaschine basierend auf
einer Peer-to-Peer (P2P)-Architektur. MINERVA setzt auf die in der P2P-Welt verbreitete Technik verteilter Hash-Tabellen auf
und benutzt diese zum Aufbau eines verteilten Verzeichnisses. Peers in unserem Ansatz entsprechen v?llig autonomen Benutzern mit ihren lokalen Suchm"oglichkeiten, die bereit sind, ihr lokales
Wissen und ihre lokalen Suchm?glichkeiten im Rahmen einer Kollaboration zur Verfügung zu stellen. Wir formalisieren unsere
Systemarchitektur und beschreiben das zentrale Problem einer effizienten Suche nach vielversprechenden Peers für eine konkrete
Anfrage innerhalb des Verbundes. Wir greifen dabei auf existierende Methoden zurück and passen diese an unseren Systemkontext
an. Wir pr?sentieren Experimente auf realen Daten, die verschiedene dieser Ans?tze vergleichen. Diese Experimente zeigen,
dass die Qualit?t der Ans?tze variiert und untermauern damit die Wichtigkeit und den Einfluss einer leistungsstarken Methode
zur Auswahl guter Datenbanken. Unsere Experimente deuten an, dass eine geringe Anzahl sorgf?ltig ausgew?hlter Datenbanken
typischerweise bereits einen Gro?teil aller relevanten Ergebnisse des Gesamtsystems liefert. 相似文献

This report examines 174 young children's language outcomes in the Bucharest Early Intervention Project, the first randomized trial of foster placement after institutional care. Age of foster placement was highly correlated with language outcomes. Placement by 15 months led to similar expressive and receptive language test scores as typical age peers at 30 and 42 months. Placement from 15 to 24 months also led to dramatic language improvement. In contrast, children placed after 24 months had the same severe language delays as children in institutional care. Language samples at 42 months confirmed that placement after 24 months led to lower expressive skill. 相似文献

Embryoid body (EB) formation forms an important step in embryonic stem cell differentiation invivo. In murine embryonic stem cell (mESC) cultures EB formation is inhibited by the inclusion of leukaemic inhibitory factor (LIF) in the medium. Assembly of mESCs into aggregates by positive dielectrophoresis (DEP) in high field regions between interdigitated oppositely castellated electrodes was found to initiate EB formation. Embryoid body formation in aggregates formed with DEP occurred at a more rapid rate-in fact faster compared to conventional methods-in medium without LIF. However, EB formation also occurred in medium in which LIF was present when the cells were aggregated with DEP. The optimum characteristic size for the electrodes for EB formation with DEP was found to be 75-100 microns; aggregates smaller than this tended to merge, whilst aggregates larger than this tended to split to form multiple EBs. Experiments with ESCs in which green fluorescent protein (GFP) production was targeted to the mesodermal gene brachyury indicated that differentiation within embryoid bodies of this size may preferentially occur along the mesoderm lineage. As hematopoietic lineages during normal development derive from mesoderm, the finding points to a possible application of DEP formed EBs in the production of blood-based products from ESCs. 相似文献

The archaeological site Pinara, southwest Turkey, which includes several remarkable objects of cultural heritage, has been the focus of several previous archaeoseismic studies. One of these examined the setting of the Roman theater in the east of Pinara by a lidar survey. A gross inclination of the stone rows of the auditorium of 0.81° towards N 314°E was interpreted as a consequence of recent coseismic tectonic movements. A new survey of the theater with a terrestrial phase laser scanner is the basis for a model with 15 times higher resolution and 28 times more data points. Parallel to the fieldwork in this study, the process and accuracy of the leveling of the 3D point clouds produced by the scanner was tested in a series of experiments. Based on the orientation of the blocks forming the seats of the theater, we suggest six sections with changing average inclination of the seats and a fault line separating a northern and a southern section. While the previously found overall inclination of the auditorium is confirmed by the new model and the dip direction agrees, the inclination is 0.58° compared to previously determined 0.81°. The almost perfect increase of inclination with the height of the first 10 entire seating rows and the nearly constant inclination from row 11 onward, makes systematic measurement errors during the construction a possible cause. This is an alternative scenario to the interpretation of a coseismic displacement of the conglomerate block on which the theater was built. 相似文献
