The flipped classroom (FC) model has emerged as an innovative solution to improve student‐centered learning. However, studies measuring student performance of material in the FC relative to the lecture classroom (LC) have shown mixed results. An aim of this study was to determine if the disparity in results of prior research is due to level of cognition (low or high) needed to perform well on the outcome, or course assessment. This study tested the hypothesis that (1) students in a FC would perform better than students in a LC on an assessment requiring higher cognition and (2) there would be no difference in performance for an assessment requiring lower cognition. To test this hypothesis the performance of 28 multiple choice anatomy items that were part of a final examination were compared between two classes of first year medical students at the University of Utah School of Medicine. Items were categorized as requiring knowledge (low cognition), application, or analysis (high cognition). Thirty hours of anatomy content was delivered in LC format to 101 students in 2013 and in FC format to 104 students in 2014. Mann Whitney tests indicated FC students performed better than LC students on analysis items, U = 4243.00, P = 0.030, r = 0.19, but there were no differences in performance between FC and LC students for knowledge, U = 5002.00, P = 0.720 or application, U = 4990.00, P = 0.700, items. The FC may benefit retention when students are expected to analyze material. Anat Sci Educ 10: 170–175. © 2016 American Association of Anatomists. 相似文献

The Astilbe Buch.-Ham. ex D. Don was founded in 1912. There are
now 18 species throughout the world. USSR, Thailand, Indonesia, Bhutan, Nepal d Kashan-
mir each has only 1 species; Korea, Philippines and USA each has 2; India 3; Japan 6; and
China 7 (including 3 endemics and 1 new variety). And northeast China, north China and
northwest China each has 2; central China and southwest China each 4; eastern China 5.
Thus the distribution centre of this genus seems to be in the region covering Japan and
eastern, central, and southwest China.
This genus is divided into two sections: Sect. Simplicifoliae Engl. and Sect. Astilbe.
Sect. Simplicifoliae may be considered as the primitive one because it has 5 ordinary petals.
This section consists of about 10 species: 5 in China (east China 4; southwest China 3; ce-
ntral China, north China and northeast China each 2; Northwest China 1), 5 in Japan, 2
in Korea, 1 in Philippines and India each. According to the distribution of this section, the
author suggests that the centre of origin of this genus be in the forested parts from Japonthrough east China to southwest China. 相似文献

在众多认知能力当中,范畴化是最重要的.范畴化,即异中求同.认知经济和认知世界结构是范畴化的两个原则.这些原则在分类学中应用广泛,特别是对基本层次范畴产生重大影响. 相似文献

The classical and numerical taxonomy, palynology and the geographical dis-
tribution of the Genus Schizopepon are dealt with in the present paper. Having comme-
nted on various opinions regarding the systematic position of the genus, the present au-
thors consider that C. Jeffrey’s treatment of Schizopepon as a new and monogeneric tri-
be, Schizopeponeae, should be supported.
The gross morphological characters in the genus are assessed from the taxonomic
point of view. Some characters, such as stamens with an elongated connective or not,
different insertions of ovules and various forms of ovaries and fruits, may be used for
distinguishing subgenera.
The pollen grains of all the species were observed under light microscope (LM) and
scanning electron microscope (SEM). The results show that a strong differentiation
has taken place in the pollen of the genus, and in consequence it may be regarded as an
important basis for dividing subgenera and species. Especially it should be pointed out
that degrees of development of colpi and positions of ora are positively correlated with
the external characters used for distinguishing subgenera.
According to the morphological and palynological characters, the genus Schizopepon
may be divided into three subgenera and eight species: 1. Subgenus Schizopepon: 5 spe-
cies, S. bryoniaefolius Maxim., S. monoicus A. M. Lu et Z. Y. Zhang, S. dioicus Cogn.,
S. longipes Gagnep. and S. macranthus Hand.-Mazz.; 2. Subgenus Rhynchocarpos A. M.
Lu et Z. Y. Zhang: 1 species, S. bomiensis A. M. Lu et Z. Y. Zhang; 3. Subgenus Neoschi-
zopepon A. M. Lu et Z. Y. Zhang: 2 species, S. bicirrhosus (C. B. Clarke) C. Jeffrey
and S. xizangensis A. M. Lu et Z. Y. Zhang.
The 8 OTU’s including all the species of this genus and 31 characters, of which 16 are morphological characters and 15 palynological characters, were used in the numerical taxonomic treatment. After standardization of characters, the correlation and distance matrices were computed. The correlation matrices are made to test the various clustering methods. At last, the UPGMA clustering method was selected and its result
is shown in the form of phenogram. The result of numerical analysis is similar to that of the classical classification.
Schizopepon Maxim. is a genus of East Asia-Himalayan distribution. China has all 8 species and 2 varieties, of which 6 species are endemic. Based on the statistics of spedies number, the distribution centre of the genus is considered to be in the Hengduan Mountains (Yangtze-Mekong-Salwin water divides) and the adjacent areas of the southwest China. 相似文献

Learning outcomes as a concept has encountered a revival since the beginning of the Bologna process in 1999. The concept itself has a longer history with its roots in the behaviourist tradition of the 1960s. The goal of this review is to study how the historical roots of learning outcomes are noted in current research articles since the launch of the Bologna process and whether the concept of learning outcomes is used critically or uncritically. The review of 90 articles shows that the behaviourist tradition is still evident in the 21st century research with 29% of the articles directly and 11% indirectly referring uncritically to the respective publications or to the behaviourist epistemology. Only a minority of the articles, i.e. 8%, was found to be critical towards the behaviourist meaning of learning outcomes. 相似文献
