Assessing visibility,legibility and comprehension for interactive whiteboards (IWBs) vs. computers

The usability of interactive whiteboards vs. computers was evaluated on three dimensions (visibility, legibility and comprehension) in the secondary school pupils. The visibility assessment consisted in detecting a visual stimulus varying in luminance using a staircase procedure, legibility was assessed with a target-search task, and we administered narrative and explanatory texts with or without illustrations to evaluate comprehension. The results of the visibility test showed that pupils found the light signal easier to detect on the IWB. For the legibility test, we observed differences in error rates and discriminability according to medium, font size and congruence between target and the distractor letters. Performances in the comprehension test were similar for both explanatory and narrative texts. Moreover, the presence of illustrations does not improve comprehension. These results could be related to the hierarchical structure of the texts, which facilitate comprehension.

Acquisition of three word knowledge aspects through reading

A number of studies have shown that second or foreign language learners can acquire vocabulary through reading. The aim of the study was to investigate (a) the effects of reading an authentic novel on the acquisition of 3 aspects of word knowledge: spelling, meaning, and collocation; (b) the influence of reading on the acquisition of partial and deeper knowledge of the words; and (c) the relationship between word frequency and learning gains. The results show that there was significant improvement in all three aspects of word knowledge. The measuring instrument detected greater partial than deeper knowledge gains in word meanings and collocations. The greatest learning gains in all three aspects of word knowledge were demonstrated for the words that occurred between 11 and 20 times in the text. The findings suggest that incorporation of extensive reading into language learning programs can contribute to significant improvement of learners' vocabulary knowledge.

由影视剧作的改编所想到的

在科学技术高度发达、人们尽情享受现代化物质文明的同时,一个不容忽视的问题应引起高度重视.不少人以影视观赏代替文本阅读,长此以往,人们(尤其是青年学生)创造性的思维力和想象力被遏制,写作能力低下.影视观赏固然能带给人们无尽的快乐,但它对人也有负面影响.呼吁多些文本阅读,少些影视观赏,以发展和张扬人的主体个性、想象力和创造力.
