This research is to examine the students‘motivational factors and attitude towards the learning ofEnglish grammar in a Computer-supported LearningSystem. Twenty-nine students were taught with astudent-centered approach and three grammar learningweb sites were used frequently for classroom andindividual English grammar practice, whereas anothertwenty-nine were taught with the traditional teachercenteredapproach. Both groups were given grammarcorrection and explanation tests before and after thestudy. After comparing the results of the pre-test andpost-test with those of the control group, it was foundthat the experimental group excelled over the controlgroup in both grammar correction and grammarexplanation. It proved that students‘ implicit andexplicit knowledge on English grammar was greatlyimproved by the computer-supported teaching methodsand environment. Further interviews with the studentsalso revealed that the new pedagogical practice hadprovided many positive motivational factors insupporting students‘ learning process.Keywords: motivation, grammar, computer-supportedclassroom.

Objective: Soccer has a reduced overall recovery time. If these situations are not properly controlled they can cause the athlete chronic fatigue, an increase in delayed-onset muscle soreness (DOMS) and thus result in a decrease in athletic performance. There are several therapies that have attempted to improve athletic performance, decrease the percentage of injuries and results in soccer. Training and recovery instances are opportunities to find ways to address this issue. Understanding the physiology of recovery is essential to accelerate some processes, with the aim of shortening the times. Subjects: Cryotherapy could improve functional performance tests and decrease pain in soccer players. Our work design is an experimental prospective study. Method: Twenty subjects (10 experimental subjects and 10 control group subjects), between the ages of 17 and 23, who are members of a university men's soccer team, participated in the study. The following variables were controlled: power; the number of jumps, the average height of a jump in a 30-second continuous jump test, and DOMS perception through visual analog scale (VAS). Both groups shall be subjected to a more active recovery as well as elongation carried out by the coaching staff. In addition to this, the experimental group shall also be subjected to ice baths (42-47 °F) for three minutes. Results: We found significant statistical differences in the number of jumps and the power of the same in the control group, thus obtaining improvements. No significant differences were observed in either group for the average jump height and percentage yield variables. In the assessment of DOMS significant differences were observed, with a lower perception of DOMS seen in the experimental group. Conclusion: Ice baths provide favorable results in some aspects of the 30-second continuous jump test, decreasing the perception of leg pain and fatigue, and therefore they can be considered a valid alternative in the management of these athletes.

Even though student questioning is the key aspect of inquiry learning, students ask very few questions in Science classrooms. This research aimed to increase the number of high-level questions posed by primary students during science lessons. An experiment was designed in which the experimental group was taught about the taxonomy of questions that can be asked by students during a science lesson. The quality of selected student questions was discussed as a whole class throughout the implementation. In addition, the experimental group completed the textbook activities at the end of each section in groups, whereas, the control group finished these activities individually. The experiment lasted for 4 weeks (12 lessons), during the ‘Microscopic Organisms and Environment’ unit in two 4th-grade classrooms. After completing each section of the unit, student questions were collected. The questions were classified as either low-level or high-level questions. The findings showed that in the experimental group, there were significantly more high-level questions compared to the control group. The questions were longer and more comprehensive in the experimental group. In both groups, as students’ achievement increased, so did the number of questions they asked. Keywords: student questions, high-level questions, question taxonomy, primary science.

This paper shows the results of production and chemical compo­sition of cow’s milk on a farm MILKO-HF, Prilep, R. Macedonia with capacity of 100 cows of Holstein-Frisian breed divided into two groups (control and experimental). In control group I which was fed in a standard way of nutrition (ration used on the farm), average daily production of milk per cow ws 22.49 kg with the following chemical composition of milk: average daily content of milk fat is 3.75%, protein 3.57%, lactose 4.65%, nonfat dry matter 9.56% and total dry matter 13.31%. In experimental group II which were fed with the ration according to normatives, average daily production of milk per cow is 24.04 kg with the following chemical composition of milk: average daily content of milk fat is 3.99%, protein 3.57%, lactose 4.65%, non-fat dry matter 9.58% and total dry matter 13.57%. The obtained results show the increase in milk production for 1.55 kg-6.89% and better chemical composition of milk in the experimental group of cows. Thus, dry matter was increased from 13.31% to 13.57%-1.95%, milk fat content from 3.75% to 3.99%-6.4%, nonfat dry matter from 9.56% to 9.58%-0.21%, while the content of protein and lactose stayed on equal level. It was determined that the normed nutrition has influenced on production increase and better chemical composition of milk without unnecessary spent high level of nutrient i.e. nutrition of cows according to recommended normative.

Background Wayfinding has been adopted in several intense evacuation and navigation simulations; however, the use of biometric measurements for characterizing physiological outcomes has been somewhat overlooked and applied only under limited laboratory conditions. Methods Twenty-four participants took part in a virtual reality (VR) experiment using a wayfinding installation with the Oculus Rift S head-mounted display (HMD). They were immersed in a simulation of a burning underground parking lot and tasked to navigate to the exit. The purpose of this research was to investigate the high-level effect of wayfinding assistive lights on behavioral, physiological, and psychological outcomes. Participants were split into two groups: the control group was exposed to a scene without assistive lights, and the experimental group was exposed to the same scene with assistive lights. Results Results indicate there was no statistically significant difference between the groups in traveled distance, pauses, turns, or game completion time. Curiously, differences between the two groups in heart rate (HR) outcomes were found to be statistically significant, with subjects in the control group displaying an increasing HR trend during simulation. Conclusions This finding, in accordance with previous studies that have shown the efficacy of landmarks and wayfinding affordances in reducing cognitive demands, suggests that assistive lights might contribute to improved brain wiring connectivity during the game. We discuss these findings in the context of a rich wayfinding affordances literature.

The article reveals the course of diagnosis of health competence of a future biology teacher. The complexity and structure of the studied phenomenon were revealed under such criterions: motivational-value (motives, needs, value orientations), cognitive-informational (mastery of health-preserving knowledge and skills), practical-activity (health-preserving skills) criteria. Experimental work was carried out in two stages: ascertaining and forming. At the ascertaining stage the organization of  educational process of future biology teachers was comprehensively investigated. The initial low level of health competence of future biology teachers was determined, which showed no significant difference between the levels of health competence of future biology teachers according to motivational-value, cognitive-informational, practical-activity criteria. According to the results of the ascertaining stage of the research, a formative experiment was carried out, which proved the existence of a high level of health competence of future biology teachers on motivational-value, cognitive-informational, practical-activity criteria in experimental and average in control groups. It was found that the students of the experimental group showed higher levels of health competence. It is proved that in the experimental group of students there have been significant changes in the direction of increasing the level of health competence. The obtained data from the experimental group in comparison with the indicators from the control group indicate that the efficiency of using the whole set of proposed innovations is higher than using them separately, without further updating.

Objective: It was investigated whether providing an explanation for a take-over request in automated driving influences trust in automation and acceptance.Background: Take-over requests will be recurring events in conditionally automated driving which could undermine trust as well as acceptance and, therefore, the successful introduction of automated vehicles.Method: Forty participants were equally assigned to either an experimental group provided with an explanation of the reason for a take-over request or a control group without explanations. In a simulator drive, both groups experienced three take-over scenarios that varied in the obviousness of their causation. Participants rated their acceptance before and after the drive and rated their trust before and after each take-over situation. Results: All participants rated acceptance on the same high level before and after the drive, independent of the condition. Control group’s trust ratings remained unchanged by take-over requests in all situations, but the experimental group showed decreased trust after experiencing a take-over caused by roadworks. Participants provided with explanation felt stronger that they had understood the system and the reasons for the take-overs.Conclusion: A take-over request did not lower trust or acceptance. Providing an explanation for a take-over request had no impact on trust or acceptance, but increased the perceived understanding of the system.Application: The results provide insights into users’ perception of automated vehicles, take-over situations and a fundament for future interface design for automated vehicles.

One of the important branches of the Armed Forces of Ukraine is the engineering troops, the units of which are always present in the organization and conduct of combat operations. The servicemen of these units do a great job of fortifying combat positions, building barriers and obstacles, masking and covering military positions with mine explosive devices, arranging water crossings, helping in organizing shelters for manpower and equipment. The theory and especially the practice of military engineers show the need to improve not only theoretical knowledge, skills and practical skills, but also to have a high level of development of general and special physical qualities. Among the many studies of physical fitness of cadets of different military specialties, there is a lack of studies of engineering cadets. The research carried out earlier concerned mainly the operator specialties of the engineering troops. Military mechanical engineers and command personnel have not been investigated at all. The purpose and objectives of the research are aimed at finding ways to improve the level of physical and psychophysiological readiness of cadets of the Higher Educational Institutions of Higher Education - future specialists of the engineering profile and determining the influence of the author's program of physical training on their professional readiness. The research methods used included theoretical methods (analysis and generalization of literary sources), pedagogical (observation, testing, experiment), methods of mathematical statistics for processing experimental data and assessing reliability. During the academic year, 60 cadets of the National Academy of Ground Forces (mechanical engineers and commander engineers) took part in the study, divided into experimental and control groups by the method of paired comparisons. The experimental group performed a specially developed physical training program with the inclusion of applied exercises. As a result of one-year training following the results of control tests, cadets of the experimental group have significantly better indicators of psychophysiological, physical (especially strength) and professional training than cadets of the control group at the level of p <0.05. Conclusions. It has been determined that for mechanical engineers and commanders for their professional activities, good strength training is important. Sense of temporal, power and spatial parameters in all subjects is approximately at the same level. EG cadets significantly improved the results of physical and psychophysiological fitness. It was found that the existing program of physical training at VVUZ does not sufficiently contribute to the high-quality special training of engineering cadets. The proposed content of exercises and the scheme of distribution of loads for a week and a month can be used to develop programs for special physical training for specific engineering specialties. Key words: military engineers, special physical training, temporary, power, spatial sense.

The structure of competitiveness of managers in international trading companies includes motivational, adaptive mobility, emotional-volitional, communicative, and individual-psychological factors. Variables of each factor characterize leadership traits and determine the competitiveness of the individual. We proved that the leadership characteristics determining competitiveness on the motivational factor are manifested in the superiority of direct motives; according to the emotional and volitional factor – a high level of volitional self-control and perseverance; according to individual-psychological characteristics – a level of emotional balance, communicativeness and a low level of depression and neurotic spontaneity.
