The main principles of project teaching, the technology of its adoption in teaching process, and some kinds of projects used in studying are reviewed. During the research the following methods were used： theoretical analysis, empirical, and statistical. While studying the course ＂Professional foreign language＂, the monitoring of effectiveness of project method use in teaching a foreign language was made. Monitoring was conducted under the following criteria： percent of progress, percent of quality of knowledge, and the level of motivation in studying English. The experience showed that in the process of project work learners＇ general educational abilities, special abilities, and communication abilities are developed.展开更多

It is hard to think about the effects of solar activity and volcano effects, because the pre- dictions of both solar activity and volcano effects are difficult. But as we know, the sun is the source of en- ergy for the Earth＇s climate system, and observations show it to be a variable star.展开更多

Yet, very little critical research has been performed to understand how to assess these effects. The relationship between infrastructure investments and regional economic development is complex and indirect, and many theoretical and methodological difficulties remain. On the one hand, the assumption that investing in infrastructure is important to sustain economic growth is sometimes doubted. On the other hand, it is argued that investments in infrastructure enhance the accessibility of urban regions and that in the slipstream of such investments, social problems in urban regions can be tackled as well. Despite these contrasting views, there is at least a consensus that transport infrastructure development depends on economic development and vice versa. Yet, in many cases, the method of assessing economic impacts highly affects the results. Therefore, this paper focuses on a critical reflection of methods for estimating economic effects of infrastructure investments. A critical evaluation is made based on Indonesian and Japanese cases. After conducting in-depth desk research on both cases, we found that the broader effects on affected group of people tend to be overlooked due to the problems of time and space dimensions, the chain reaction of effects, and inappropriate data practices. The assessment on the appraisal processes tends to overlook the broader economic implication due to narrow focus and the concept of efficiency of economic theory.展开更多
