The ionization theory attributes this phenomena to the interaction of water ions with the ions of dissolved salts, resulting the formation of an excess of hydrogen or hydroxyl ions. The concentration of hydrogen or hydroxyl ions in water is very low, they are in equilibrium with an immense number of unionized water molecules. When one of them is bound by the ions of the salt, the equilibrium is disturbed, causing new water molecules to ionize, which leads to accumulation an excess of quantities of the other ion, making the solution react acid or alkaline.
Any salt can be obtained by neutralization of acids by bases. It is natural to assume, therefore, that solutions, at least those witch are products of complete displacement of hydrogen in acids by metals, must react neutral. However, this assumption holds only for salts of strong acids and strong bases. Salts of weak acids and strong bases, or vice versa, of strong acids and weak bases, do not react neutral when dissolved in water.
The methods handbook covers the basic material on the subject ”Hydrolysis of salts of distinct nature” that may reasonably be required from Ordinary Level university standard for the trade 18.03.01 “Engineering chemistry”, in particular, when making a study in Ufa State Petroleum Technological University.
Semester curriculum (SC) is one of the elements which provide quality mastering of principal educational program (PEP) on some program track. This curriculum modernizes base curriculum up to actuallyacademic year’s conditions and determines such quality indicators as federal state educational standard identity, equitability of teaching load for every student through the semester, making different kind of activity according by student’s self-study, discipline study’s sequence.
It’s offered in the article to use PEP in order to optimize educational process by reducing the number of disciplines studying at the same time, and also by reducing the time between discipline studying and getting interim assessment (for example on the assessment weeks). In order to realize this idea, it’s offered to use series parallel scheme of PEP building. This scheme is based on that studying time depends on its workload, and «floating» studying start. It means that some disciplines begins, for example, on the second third of semester and ends on the second assessment week by getting interim assessment. In order to realize offered PEP building scheme it is necessary to use point-rating system (when assessment is set only by getting points) and to maintain educational process’ schedule as by students, as by lectures.
Using such kind of semester curriculum allows to improve the quality of PEP maintaining and to increase marketability of USPTU graduate.
METHODS FOR ASSESSING RELIABLE TEST BASED ON A NUMBER OF TEST DATA (FOR EXAMPLE, THE EXPERIENCE OF THE IMPLEMENTATION OF THE SCORE-RATING SYSTEM AT THE DEPARTMENT OF MATHEMATICS USPTU)
Testing of the same group of students over a sufficiently long period of time allows the researcher to explore how to set and testological specific tasks and look for new approaches to solving traditional problems. This article is devoted to estimation of the reliability of test results, conducted as the current control and intermediate level students mastering the material covered in the framework of score-rating system (BRS). It is obvious that the test results are inherently random variables, however, fail the test built able to greatly increase the instability of the results, make an extra (often systematic) errors that may call into question the reliability of the results and the adequacy of the following conclusions. Available theoretical methods are not always realizable in practice, since it implies, for example, re-test the same group of students (test-retest method, parallel forms).
The author examines the approaches based on the analysis of several consecutive tests. These approaches use the apparatus of mathematical statistics, firmly entered into the everyday life of practicing psychologists and educators. If within a relatively short period of time is carried out several tests on the same stream (albeit in different sections), the results must obviously be sufficiently strongly correlated. At the core of this thesis is the assumption of the constancy of the latent high-level parameters such as basic training of the student, the properties of his personality, motivation to learn, etc. If the tests are reliable, the more volatile factors – the level of preparation of students for a particular test, against this background that brings results in relatively minor variations. As a measure of statistical association tightness using correlation coefficient and Spearman’s rank correlation coefficient. The article also discusses the limitations in the use of re-testing and possible applications of analysis of variance to the stated problem.
DETERMINATION OF PHYSICAL HEALTH STATUS AT PHYSICAL EDUCATION LESSONS BY THE EXAMPLE OF THE UFA STATE PETROLEUM TECHNOLOGICAL UNIVERSITY
It is worded about the main problems of the modern society: low health state, increase of heart diseases and low lifetime in our country. According to the different researches, only 10% of young people have a normal health level. So students of the USPTU also have not perfect health indicators. In 2014 according to our clinic information among first year students only – 24% are healthy and – 76% are unwell. A lot of students have 2-3 chronic diseases. What is more these records worsen every year. As a result of such low young people’s physical development indicators, production potential of our country is going down. Not every physical exercises can improve our health. Some scientific researches proved that rough labor which is mixed with the power components can’t improve health level, moreover it develops degenerative diseases of the cardio – vascular system. Today health benefits and prevention of coronary heart diseases are connected with not every hard quantified motor activity, only they are linked with the value of total endurance and working ability, which is the criterion of maximum oxygen consumption value. Physical education should contribute to preservation and improving people’s health. Prevention and treatment of cardio – vascular system diseases demands elaboration of effective contestation arrangements against hypodynamy, as well as practical application of modern test for assessing the functional status of the various organism systems, also the use of effective preventive programs training. The article shows facts about the positive influence of physical exercises on health that improve stamina. According to Cooper test (12 min.run), maximum oxygen demand was calculated and MOD table determined levels of physical state in educational group and track and field sport groups. There are suggestions, given at the end of the article that will probably improve work of physical training chair to preserve and improve health state of students.
Electronic training complexes play an important part understanding of new studying material. They help to understand the complicated processes that are often hidden from view. Various operations connected with the calculations, drawings and visual representation of the object cause difficulties. There are several types of electronic training complexes, their aim is to systematize educational material, mathematical calculations and modeling of mechanical and technological processes.
Owing to the three-dimensional modeling electronic training complexes give information, allow to observe the mechanical processes, to examine technical device of machines and apparatus.
For solving the problem of mechanical gears visualization the variant of training complex is suggested. It is a collection of the main types reducers’ dismantling video demonstrations.
In the work the main stages of computer program are analyzed development.
The gear models were created in program “Compass 3D” with the help of three-dimensional computer modeling. Their usage helps to demonstrate mechanism dismantling. An interface of the complex, allows a user to select the desired gearbox for visualization.
An application of training complex will help to solve the problem of the mechanisms’ spatial representation and to optimize the studying process of the subject “Machine parts and bases of designing”.
