In Trubilin State Agricultural University of Kuban there are created machinery working devices as screw drums allowing the assurance of motion of bulk particles at their horizontal location and also promoting the intensity of particles interaction between each other and with the walls of screw drums which widens technological potentialities and decreases dimensions of equipment and its weight. In the paper there are shown various sorts of screw drums and analytical methods of the study of physical phenomena taking place in the contact area of bulk particles. The search of a screw drum design was carried out by the methods of descriptive geometry and engineering graphics with the aid of the “Compass-3D” program complex. The apparatus of dimensionless kinematic functions (similarity invariant) and the analysis of dimensionalities allowing the investigation not one such a case but their infinite number united by the community of properties was used.

Optimal Modeling

Development of the designer’s documentation package by means of CAD systems implies good skills with toolkits of solid and surface modeling. The ability to identify the surface type, its generation process and consequently to choose the optimal modeling is acquired in the descriptive geometry course, as well as engineering graphics and computer graphics courses. The article describes training assignments designed for students of machine building departments aimed both at consolidation of theoretical knowledge and development of skills required to identify and model various surface types.

Definition Of

Everyone knows that descriptive geometry is a science, but there is no definition of the computer graphics. If computer graphics is announced as a science, you can continue to call descriptive geometry outdated and to demand of its abolition. But if the computer graphics has nothing to do with the science, and if it is only a tool to perform the procedures of descriptive geometry and other branches of geometry, everyone who tried to discredit descriptive geometry, will be in a difficult position: they will have nothing more to say, because in it is unwise to replace science on tool. It is known that engineering graphics so far does not have the status of science. It is a discipline that fully applies the laws of other geometrical sciences. There are many questions such as: why are there claims that descriptive geometry is 2D? Why do some specialists claim that descriptive geometry is a projection on a single plane? They forgot that descriptive geometry uses the method of two images or method of two traces. But this method of two images is used everywhere! On the first lecture we tell students: the projection is carried out on two planes of projection, a point in space can be fixed only by means of three coordinates and the point must have at least two projections. It means, that descriptive geometry works with three coordinates, in other words — in 3D. The image produced on the display screen in the so-called 3D, is neither more nor less than axonometric projection on the plane — appropriate section of descriptive geometry. In conclusion, the author offers to classify the computer graphics as a tool for the experience of all branches of geometrical science, but not as a free-standing science.

The Way

The introduction of the methodology of a competence approach in teaching the courses of departments of engineering graphics, as shows the experience of a number of technical universities of Russia, occurs according to some template. If in 70–80 years the last century the Departments was the routing of the teaching subject with the indication providing, and provide discipline then currently are talking about interdisciplinary competences. In this case, interdisciplinary competence on engineering and computer graphics define the departments. The wording of the intrasubject competencies reduced to define the topics of descriptive geometry necessary for the study of the fundamentals of engineering graphics (geometrical and projection drawing, the cutting line and the intersection of simple surfaces). In the end, the important topics of descriptive geometry (basic concepts of the theory of curves and surfaces, sweep, tangent planes, axonometric etc.) that have practical value, are excluded from the syllabus. This greatly affects the quality overall geometric training of students of technical universities with based on the level of teaching geometry in high school. In our opinion, the way out of the situation is in consistent, purposeful transformation the descriptive geometry in the engineering geometry without radical distortions. In this regard, the present article is devoted to the presentation some issues in the theory of nonlinear forms in engineering geometry. The proposed approach will enhance the practical value of our discipline due to the expansion of cross-curricular competencies with related sections of higher mathematics, CAD, etc.

The Subject

It has been determined that the drawings, photographs and pictures related to the subject of the continuity of the tangent function on page 68 of the Ministry of National Education’s twelfth-grade mathematics textbook contradict principles 1, 7 and 10 of Yanpar’s (2007) teaching material development principles. According to these principles, teaching materials should: i) be simple, plain, and understandable, ii) reflect real life as much as possible, and iii) be easy to develop or revise, if necessary. This study aims to develop a portable tangent bridge model to meet the needs of the subject of the continuity of the tangent function. With this aim: i) teaching with the analogies model in the design of the teaching material, ii) “this is my project” format in the development and iii) Yanpar’s (2007) principles were considered. The design of the model lasted 14 weeks. At the end of the study, a portable tangent bridge model from waste products was designed and developed. This model is thought to contribute to the teaching effectiveness of teachers (Shulman, 1987) with content knowledge alongside with pedagogical knowledge (Shulman, 1986). With this contribution, the needs of the subject as described by Taba (1962) and Tyler (1949) will be met. This model will also serve as an example of meeting the needs of the subjects of knowledge and its product, technology, as highlighted by Cahit Arf (Terzioglu &Yilmaz, 2006).

Descriptive Statistical Analysis

The main problem in this research is to find out the design of valid teaching materials and the practicality of teaching materials. This research is a Research & Development (R&D) research method. To develop the product, this research uses a 4-D development model consisting of four stages, namely: (1) the defined phase, (2) the design phase, (3) the development phase, and (4) the disseminate stage. This research was conducted in class V of SD Negeri 1 Lalebbata Palopo, which acted as the subject of the study was the fifth-grade students totaling 25 people. Data collection techniques in this study are: observation, documentation, Questionnaire, and Validation. Analysis of the data used by the researcher was to test its validity by using the Aiken's formula and for analyzing student questionnaire response data and observations using descriptive statistical analysis. The results of this study indicate that the integrated religious neuroscience-based teaching material is said to be valid by three validators with several revisions so that it can be said to be valid and can be tested, then this teaching material can be said to be interesting because the results from the questionnaire responses of 20 students tend to agree with teaching material developed. Thus this research needs to be socialized so that it can become a consideration of teachers in schools in improving students' writing skills.
