Teaching science to visually impaired students： A small-scale qualitative study

Students have long regarded science as a difficult subject because of hard and abstract concepts. Traditional science teaching has been depended mostly on visual instruction. This makes it difficult for visually impaired （VI） or partially sighted students included in regular classrooms to learn the concepts. Blind students on the other hand, have no visual input at all. They need to learn using other senses such as touching and hearing. Classrooms should be adapted and instruction should be adjusted for better science teaching to VI students. The purpose of this study was to investigate how VI students learn science. The results of the data obtained via interviews and observations revealed that VI students need instructional and environmental accommodations to learn science. They need more tactual and audio experiences than visual instruction. Suggestions and implications about teaching science to students with visual impairments are discussed.

Application of automated image analysis to the identification and extraction of recyclable plastic bottles

An experimental machine vision apparatus was used to identify and extract recyclable plastic bottles out of a conveyor belt. Color images were taken with a commercially available Webcam, and the recognition was performed by our homemade software, based on the shape and dimensions of object images. The software was able to manage multiple bottles in a single image and was additionally extended to cases involving touching bottles. The identification was fulfilled by comparing the set of measured features with an existing database and meanwhile integrating various recognition techniques such as minimum distance in the feature space, self-organized maps, and neural networks. The recognition system was tested on a set of 50 different bottles and provided so far an accuracy of about 97% on bottle identification. The extraction of the bottles was performed by means of a pneumatic arm, which was activated according to the plastic type; polyethylene-terephthalate （PET） bottles were left on the conveyor belt, while non-PET bottles were extracted. The software was designed to provide the best compromise between reliability and speed for real-time applications in view of the commercialization of the system at existing recycling plants.     

Cognitive Analysis of There-be Construction

In the circle of linguistics,numerous attempts have been made to explore there-be construction in the fields of syntax,semantics,and pragmatics,but in the by-now researches there is little touching on the derivation of the word there.In consequence,herein the focus and effort are put on the derivation of there.It explores the motivation behind the derivation of there based on the cognitive study on there constructions.It is demonstrated that there-be construction derivates to meet the need of the development of human cognitive capacities of expressing abstract mental space.It is mainly motivated by gestalt law,figure-ground theory.
