Teaching methods
To enhance the quality of instruction in the "Parts and Assemblies of Technological Machines" course, we utilize modern educational technologies focused on actively engaging students and developing their engineering competencies: Interactive lectures use of multimedia presentations, animations, and 3D models of components and mechanisms; discussion of examples from real-life mechanical engineering production. Problem-Based Learning (PBL) setting engineering problems that require independent solution discovery; working on case studies from the design of parts and assemblies. Project-Based Learning completion of mini-projects on the calculation and design of individual machine components; project defense in the form of presentations and technical reports. Computer Modeling (CAD/CAE) use of software packages (SolidWorks, AutoCAD, ANSYS, etc.) for modeling parts and performing engineering calculations; mastering modern digital engineering methods. Elements of distance and blended learning posting educational materials, tests, and assignments on an LMS platform (Moodle, Canvas, etc.); conducting online consultations and testing. Game and training technologies use of simulators to analyze the operation of mechanisms; business and role-playing games to discuss decisions on selecting the optimal design of components. Critical thinking technologies analysis of various design solutions and their comparative evaluation; developing students' skills in reasoned choice and decision-making.
Assessment of the student's knowledge
Teacher oversees various tasks related to ongoing assessment and determines students' current performance twice during each academic period. Ratings 1 and 2 are formulated based on the outcomes of this ongoing assessment. The student's learning achievements are assessed using a 100-point scale, and the final grades P1 and P2 are calculated as the average of their ongoing performance evaluations. The teacher evaluates the student's work throughout the academic period in alignment with the assignment submission schedule for the discipline. The assessment system may incorporate a mix of written and oral, group and individual formats.
| Period | Type of task | Total |
|---|---|---|
| 1 rating | Each student is given an individual assignment for rating | 0-100 |
| 2 rating | Each student is given an individual assignment for rating | 0-100 |
| Total control | Exam | 0-100 |
The evaluating policy of learning outcomes by work type
| Type of task | 90-100 | 70-89 | 50-69 | 0-49 |
|---|---|---|---|---|
| Excellent | Good | Satisfactory | Unsatisfactory | |
| In accordance with section 8, "The policy of assessing students' academic achievements" of the AP NAO "VKTU" 029-III-2022 Academic Policy of the NAO "VKTU named after D. Serikbayev" | "Excellent" (90-100%) — the student has full knowledge, is able to apply theory to solve practical problems, performs calculations without errors, shows independence and initiative. | "Good" (70-89%) — the material has been sufficiently mastered, minor errors in calculations and conclusions have been made, the student is capable of independent work. | "Satisfactory" (50-69%) — knowledge is limited, mistakes are made when solving computational problems, and the help of a teacher is required. | "Excellent" (90-100%) — the student has full knowledge, is able to apply theory to solve practical problems, performs calculations without errors, shows independence and initiative. |
Evaluation form
The student's final grade in the course is calculated on a 100 point grading scale, it includes:
- 40% of the examination result;
- 60% of current control result.
The final grade is calculated by the formula:
| FG = 0,6 | MT1+MT2 | +0,4E |
| 2 |
Where Midterm 1, Midterm 2are digital equivalents of the grades of Midterm 1 and 2;
E is a digital equivalent of the exam grade.
Final alphabetical grade and its equivalent in points:
The letter grading system for students' academic achievements, corresponding to the numerical equivalent on a four-point scale:
| Alphabetical grade | Numerical value | Points (%) | Traditional grade |
|---|---|---|---|
| A | 4.0 | 95-100 | Excellent |
| A- | 3.67 | 90-94 | |
| B+ | 3.33 | 85-89 | Good |
| B | 3.0 | 80-84 | |
