An approach for generating interactive 3D graphical visualization of the genetic architectures of complex traits in multiple environments is described. 3D graphical visualization is utilized for making improvements on traditional plots in quan- titative trait locus (QTL) mapping analysis. Interactive 3D graphical visualization for abstract expression of QTL, epistasis and their environmental interactions for experimental populations was developed in framework of user-friendly software QTLNetwork (http://ibi.zju.edu.cn/software/qtlnetwork). Novel definition of graphical meta system and computation of virtual coordinates are used to achieve explicit but meaningful visualization. Interactive 3D graphical visualization for QTL analysis provides geneticists and breeders a powerful and easy-to-use tool to analyze and publish their research results. 相似文献

Visualizations are an increasingly important part of scientific education and discovery. However, users often do not gain knowledge from them in a complete or efficient way. This article aims to direct research on visualizations in science education in productive directions by reviewing the evidence for widespread assumptions that learning styles, sex differences, developmental stages, and spatial language determine the impact of visualizations on science learning. First, we examine the assumption that people differ in their verbal versus visual learning style. Due to the lack of rigorous evaluation, there is no current support for this distinction. Future research should distinguish between two different kinds of visual learning style. Second, we consider the belief that there are large and intractable sex differences in spatial ability resultant from immutable biological reasons. Although there are some spatial sex differences (in some types of spatial tests although not all), there is actually only very mixed support for biological causation. Most important, there is conclusive evidence that spatial skills can be improved through training and education. Third, we explore educators' use of Piaget's ideas about spatial development to draw conclusions about ‘developmental appropriateness’. However, recent research on spatial development has focused on identifying sequences that begin with early starting points of skill, and spatial education is possible in some form at all ages. Fourth, although spatial language does not determine spatial thought, it does frame attention in a way that can have impact on learning and understanding. We examine the empirical support for each assumption and its relevance to future research on visualizations in science education. 相似文献

The present paper reports on a study that examined whether practical work can be said to have affective outcomes, and if so in what sense. The term ‘affective’ is used here to refer to the emotions, or feelings, engendered amongst pupils towards school science in general, or one of the sciences in particular. The study is based on 25 multi‐site case studies that employed a condensed fieldwork strategy. Data were collected, using tape‐recorded interviews and observational field notes, in a sample of practical lessons undertaken in English comprehensive (non‐selective) schools during Key Stages 3 and 4 (ages 11–14 years and 15–16 years, respectively). The findings suggest that whilst practical work generates short‐term engagement, it is relatively ineffective in generating motivation to study science post compulsion or longer‐term personal interest in the subject, although it is often claimed to do so. This suggests that those involved with science education need to develop a more realistic understanding of the limitations of practical work in the affective domain. 相似文献
