SPECIFITY AND EFFICIENCY OF COMPUTER MONITORING OF KNOWLEDGE AS A HIGHPRIORITY METHOD OF DIAGNOSIS OF THE LEVEL OF STUDENTS’ ACADEMIC ACHIEVEMENTS

Research issues of specificity and efficiency of the computer monitoring of knowledge as a high-priority method of diagnostics of the level of students’ educational attainments are made actual. The essence of the interrelated notions such as “ computer monitoring of knowledge”, “ computer testing”, “ test assignment” is revealed.On the basis of analysis of available references the objective of computer testing is defined, the reasons of figuring out the objective results which are achieved by the means of two constituents that are proper prepared test and actionable hardware system are set. At the same time the general properties of test such as validity, complexity, reliability, stability, representativeness, significancy, truthfulness, test hypothesis and discriminant are assigned. As a rule, test consists of two parts: informational and operational. The technology of constructing test tasks is characterized, it presupposes observance of number of rules: each test task should evaluate the achievements of an important and significant educational goal; it should check the appropriate level of knowledge acquisition, as well as higher cognitive levels and the time allocated for the test task which should be spent on finding the answer, but not on understanding the condition of the question. Along with that, the efficiency of computer testing is analyzed, which depends on the variability and multiplicity of created test tasks. Based on the results of the research we have the reason to confirm that computer testing being promising direction of modern educational process becomes constituent of the modern knowledge diagnostics. It broadens the means of control and evaluation of the level of educational achievements, it is an alternative to traditional methods of monitoring, it can be carried out taking into account different types and forms of control as a tool of operational management.Computer testing enables to audit knowledge of a large number of people simultaneously in a short span of time; random selection of questions from the course unit; processing of test results on a personal computer using a rating scale.

Intelligent recommendation algorithm of mobile application crowdsourcing test based on deep learning

As the functions of mobile applications become more and more complex, the crowdsourcing testing puts higher demands on the professional skills of testers. Therefore, it is an important factor to ensure test quality how to effectively match test task requirements with test personnel's skill level and achieve accurate crowdsourcing test task recommendation. This paper proposes a crowdsourcing test task recommendation algorithm for mobile applications based on deep learning. Firstly, feature analysis is carried out for testing tasks and testers, and feature systems are designed respectively. Second, the resulting characteristic data is used as input data for the Stacked Marginalized Denoising Autoencoder (SMDA). The deep feature data learned from SMDA are combined as the input of Deep Neural Networks (DNN). Finally, the learning ability of DNN is used for prediction. Experimental results show that the proposed algorithm has obvious advantages in both performance and training time compared with CDL and AUTOSVD ++, which verifies the effectiveness of the proposed algorithm. The proposed algorithm can recommend testing tasks to appropriate testers and improve the precision of the algorithm.

The Content Validity on Reading Comprehensions of National Versions of National Matriculation English Test in 2020 — Based on Bachman and Palmer Test Task Characteristics Theory

Bachman and Palmer constructed a framework based on their test task characteristics theory, and designed five parts in the framework, which furnished the validity testing research with theoretical support. Based on their framework, this paper’s research objects are the national versions of National Matriculation English Test (NMET) in 2020, as well as it tests the content validity of expected answers and text input of reading comprehension in the national versions I, II, and III. The results show that the overall quality of reading comprehension of these three papers is high, which meets the requirements of the curriculum standards and examination syllabus. However, there are shortcomings in the length, difficulty, text types and reading skills evaluation. Therefore, the article length distribution should be more reasonable, the article difficulty should be more moderate, the text types should be more diversified, and the assessment of reading skills should be more comprehensive and balanced in the future, so as to further improve and perfect the content validity of the reading comprehension of NMET.

Characteristics of the Special Physical Fitness of Paddlers at a Distance of 200 m

The aim of the study. The overall goal of this manuscript was to gain a better understanding of differences in the level of functional support for special endurance for paddlers of uniform groups (in terms of sports qualification): men kayakers, men canoeists, and women kayakers who specialize in a distance of 200 m. Material and methods. 20 qualified paddlers’ level of functionality is being assessed, among them are a group of elite athletes, the members of the Chinese national team and winners of the 2018 Asian Games. Results. The important feature of the analysis is the evaluation of the structure of the ergonomic power of a 30-second maximum load. Estimating the average value of the ergometric power of work for 25-30 seconds of operation in accordance with the average power of the entire 30-second load made it possible to determine the ratio of the anaerobic alactic and lactic abilities of the athletes, taking into account the requirements of a 200-meter race for canoe and kayak paddlers. A significant range of individual differences in the indices of reactive properties of the cardiorespiratory system, which are determined by the ratio of the partial pressure of СО2 and the maximum level of pulmonary ventilation (VE/PaCO2) during the10 and 30 second test task, attracts attention. The range of VE/PaCO2 indicators was: the relation of partial pressure СО2 to pulmonary ventilation in the 10 s test – 2.3 ± 0.8 for men kayakers; 2.3 ± 0.7 for men canoeists; 2.2 ± 0.5 for women kayakers; the relation of partial pressure СО2 to pulmonary ventilation in the 30 s test – 3.9 ± 1.0 for men kayakers; 3.8 ± 1.1 for men canoeists; 3.6 ± 0.7 for women kayakers. Conclusion. The results of the study indicate differences in the level of functional support for special endurance for paddlers of uniform groups (in terms of sports qualification): kayakers and canoeists who specialize in a distance of 200 m.

Control and benchmarking of a 7-DOF robotic arm using Gazebo and ROS

The robot controller plays an important role in controlling the robot. The controller mainly aims to eliminate or suppress the influence of uncertain factors on the control robot. Furthermore, there are many types of controllers, and different types of controllers have different features. To explore the differences between controllers of the same category, this article studies some controllers from basic controllers and advanced controllers. This article conducts the benchmarking of the selected controller through pre-set tests. The test task is the most commonly used pick and place. Furthermore, to complete the robustness test, a task of external force interference is also set to observe whether the controller can control the robot arm to return to a normal state. Subsequently, the accuracy, control efficiency, jitter and robustness of the robot arm controlled by the controller are analyzed by comparing the Position and Effort data. Finally, some future works of the benchmarking and reasonable improvement methods are discussed.

Examination of Speaking Test Performance in Structured Group Tasks

This chapter explores the use of structured group tasks in the testing of speaking skills in the context of a tertiary level first year speaking course. Participants included undergraduate university students from the department of English translation and interpreting at a state university located in Central Turkey. The structured task used in the study guided students into a group discussion during the speaking exam. The discussions in the exam sessions were video-recorded and transcribed. The transcriptions were analyzed from an interactional perspective. The students were also given an open-ended questionnaire to reveal their opinions about the ins and outs of the speaking test task tried out in the study. The questionnaire consisted of two parts. The first part required students to fill out their demographic information, and the second part inquired students' opinions about the group speaking task. The results of the analysis and questionnaire responses revealed additional opportunities provided by the use of structured tasks in speaking exams.

Theoretical and practical aspects of the development of strength and strength endurance of the abdominal muscles among university female students

A special place in the assessment of the physical fitness of university students is given to the state of individual muscle groups, including the level of strength and strength endurance of the abdominal muscles. Developed abdominal muscles play a significant role in maintaining a high level of physical performance of female students in health-improving aerobics classes, which are especially popular among girls. At present, the insufficient value of the power load in physical education classes and the low level of independent motor activity of student youth lead to a decrease in the power indicators of the abdominal muscles. The need to assess the strength endurance of the torso muscles of students involved in health-improving aerobics, as well as the choice of means and methods for its development, determined the purpose of this study, aimed at determining the initial level of development of strength endurance of the abdominal muscles of 1–4 year students. The analysis of the values obtained as a result of the fulfillment of the test task “Raising the torso from the supine position” in one minute by the 1–4 year students showed a significant discrepancy in the development of strength endurance of the abdominal muscles (Ρ < 0,05). The highest values in torso flexion were registered in the 2nd year students, after which these indicators returned to the initial level shown in the first year. In accordance with the results obtained, a scale for assessing the level of strength endurance of the abdominal muscles of female students engaged in health-improving aerobics are developed, as well as theoretical and practical aspects related to the development of strength and strength endurance of the abdominal muscles in university students are analyzed.
