AbstractICT is one of the mediums to improve the quality of education. ICT can make the teaching-learning process to be more interesting. Other than that, ICT is proved to be able to help students understanding the concept of a topic and improve the students’ mathematics ability. According to the difficulties faced by the students when learning triangles, researchers gave out questions to a random junior high school class and found out that the students’ understanding ability towards the basic concept of a triangle is still lacking. This research uses a combination of the ADDIE model and quasi-experiment to compares the class that uses Hawgent dynamic mathematics software with the class that uses the traditional teaching method. after observing the situation, researchers will then design an interactive learning media using Hawgent dynamic mathematics software that will help the student to understand the basic concept, improve their problem-solving ability. Research shows that interactive learning media such as hawgent can be used to teach triangles. The implementation result also shows that the students’ problem-solving ability that uses interactive learning media is better than that does not use the interactive learning media.

Authors: Atkina L , Bulatova L 
Published: October 2020

Abstract
Annotation. At the present time the federal program of improvement of yard areas in Sverdlovsk region is coming into effect. Therefore, a compound landscape analysis of project areas was held and the consequences of their reconstruction were assessed. The main attention was paid to the parameters which reflect the balance of the territory: the area of roads, driveways, sidewalks, children’s playgrounds, landscaping, including separately taken into account area under the lawn. Results of the research confirm that the reconstruction will reduce the area of green territories. Due to reconstruction, the share occupied by green areas, is reduced three times in two out of three of investigated yards. And only in one yard the reduction is not so significant – only by 15 %. The positive aspect implemented in all yards is a specific separation of the children’s playground. The project also includes complete removal of large trees and their replacement with a few shrubs. Eventually the research of yard area landscaping projects proves that tree-and-shrub’s planting is not prioritized and, unfortunately, due to reconstruction will be presented in a much more simplified version compared to the existing one, thus it will negatively affect the environmental situation of the city.
Investment Management Based On Key Investment Growth Spurts

Published: October 2020

Abstract
Among key factors that are perceived as crucial to the investment development within an economic system is sectoral composition. It is essential to identify those types of economic activity that define the makeup of the investment-related links between associated sectors. Based on the sector approach to investment and demand, this article looks at how the investment self-induction mechanism influences intersectoral investment dynamics. Among the outcomes of our study we is a method for identifying, based on output-input account data, key investment growth spurts. The method we suggest has been applied to the analysis of the U.S. industries’ performance. The main hypothesis we explore builds on the idea that the investment growth spurts may shortly after they have been given ample impetus launch what we call a mechanism of self-induction of investment, while also spurring the investment development within adjacent sectors of economy. The presented theoretical assumptions are backed up with empirical outcomes. In our study we made use of the data released by the US Department of Commerce. The conclusions we arrived at enable identification of the industries which, if enhanced through self-induction of investment mechanism, may generate a desired increase in the investment flows within adjacent economic sectors.
