Teachers’ cultural differences: case studies of geography teachers in Brisbane,Changchun and Hong Kong

The primary purpose of this exploratory study is to identify variations in the ways in which individual teachers in different educational contexts interpret their curriculum and plan their lessons and in particular to explore the possibility that cultural differences as identified by Hofstede (1991) may be a contributing factor to understanding how teachers understand their work. “Educational reform” has become a catchphrase in the Anglo-American world, including the United States, Canada, Australia, and England and Wales, as well as in the Confucian Heritage Areas such as Mainland China, Singapore, Hong Kong, and Taiwan. Across the world, the educational reform measures being implemented are surprisingly similar. This paper describes a study of how geography teachers in Queensland, Australia, Hong Kong, and Changchun, China, plan their lessons and curriculum. From classroom observations and interviews with the teachers involved, we confirmed marked differences in each location regarding their cultural traits of power distance, individualist and collectivist preference and uncertainty tolerance, and that these traits appear to be highly influential in their curriculum planning. Despite the small scale of this study, we contend that there are good reasons for caution before national education systems import policies and curriculum reform initiatives from other countries for unthinking adoption.     

对虾的致病性蜡状芽孢杆菌的分离及其特性

从感染“黑鳃病”的对虾中,分离出一珠对虾的致病菌,经鉴定为蜡伏芽孢杆菌。通过鳃部吸附及肌注感染,受感染的对虾迅速死亡,注射该菌株的培养上清液,对虾也迅速死亡,显示蜡状芽孢杆菌的胞外代谢物,在对虾致病过程中起着重要作用。

CBM maze-scores as indicators of reading level and growth for seventh-grade students

The technical adequacy of CBM maze-scores as indicators of reading level and growth for seventh-grade secondary-school students was examined. Participants were 452 Dutch students who completed weekly maze measures over a period of 23 weeks. Criterion measures were school level, dyslexia status, scores and growth on a standardized reading test. Results supported the technical adequacy of maze scores as indicators of reading level and growth. Alternate-form reliability coefficients were significant and intermediate to high. Mean maze scores showed significant increase over time, students’ growth trajectories differed, and students’ initial performance levels (intercepts) and growth rates (slopes) were not correlated. Maze reading level and growth were related to reading level and/or growth on criterion measures. A nonlinear model provided a better fit for the data than a linear model. Implications for use of CBM maze-scores for data-based decision-making are discussed.

Auditory processing,linguistic prosody awareness,and word reading in Mandarin-speaking children learning English

This study examined language-specific links among auditory processing, linguistic prosody awareness, and Mandarin (L1) and English (L2) word reading in 61 Mandarin-speaking, English-learning children. Three auditory discrimination abilities were measured: pitch contour, pitch interval, and rise time (rate of intensity change at tone onset). Linguistic prosody awareness was measured three ways: Mandarin tone perception, English stress perception, and English stress production. A Chinese character recognition task was the Mandarin L1 reading metric. English L2 word reading was assessed by English real word reading and nonword decoding tasks. The importance of the auditory processing measures to reading was different in the two languages. Pitch contour discrimination predicted Mandarin L1 word reading and rise time discrimination predicted English L2 word reading, after controlling for age and nonverbal IQ. For the prosodic and phonological measures, Mandarin tone perception, but not rhyme awareness, predicted Chinese character recognition after controlling for age and nonverbal IQ. In contrast, English rhyme awareness predicted more unique variance in English real word reading and nonword decoding than did English stress perception and production. Linguistic prosody awareness appears to play a more important role in L1 word reading than phonological awareness; while the reverse seems true for English L2 word reading in Mandarin-speaking children. Taken together, auditory processing, language-specific linguistic prosody awareness, and phonological awareness play different roles in L1/L2 reading, reflecting different prosodic and segmental structures between Mandarin and English.     

Item Response Models for Examinee‐Selected Items

In some tests, examinees are required to choose a fixed number of items from a set of given items to answer. This practice creates a challenge to standard item response models, because more capable examinees may have an advantage by making wiser choices. In this study, we developed a new class of item response models to account for the choice effect of examinee‐selected items. The results of a series of simulation studies showed: (1) that the parameters of the new models were recovered well, (2) the parameter estimates were almost unbiased when the new models were fit to data that were simulated from standard item response models, (3) failing to consider the choice effect yielded shrunken parameter estimates for examinee‐selected items, and (4) even when the missingness mechanism in examinee‐selected items did not follow the item response functions specified in the new models, the new models still yielded a better fit than did standard item response models. An empirical example of a college entrance examination supported the use of the new models: in general, the higher the examinee's ability, the better his or her choice of items.     

Transformation for adults in an Internet‐based learning environment—is it necessary to be self‐directed?

This research explores the relationships between self‐directed learning readiness and transformative learning theory (TLT) reflected by the Constructivist Internet‐based Learning Environment Scale (CILES). A questionnaire survey about adult learner's perceptions of Internet‐based learning was administered to adults enrolled in classes in community colleges in Taiwan. A total of 593 valid questionnaires were used for the structural equation modeling analysis. The findings confirmed a second‐order hierarchical factor relationship of TLT (technical, dialectical and emancipatory learning interests) from CILES. Moreover, the three domains of learning interests of transformative learning were proved to have a developmental relationship, moderated by the readiness of self‐directed learning for adult learners in Internet‐based learning.
