Development of students’ mathematical skills is associated with quality teaching, which means that mathematics teachers should be able to successfully solve mathematical, teaching, and professional problems. The article aims to describe the assessment system of mathematics school teachers’ professional competence, which helps identify gaps in their training and design tailor-made retraining courses. 2,359 mathematics teachers from 13 regions of Russia participated in the research on 05–29 September 2017. Foremost, we conducted a survey and collected data about their teacher category and teacher expertise. Next, we provided a preliminary diagnostic test to enable the participants to self-assess their subject matter and teaching competencies. After that, they completed a three-part diagnostic test to assess their abilities to solve mathematical, teaching, and professional problems. Finally, the participants conducted video lessons. The three-part diagnostic test and video lessons allowed determining the professional competence level for every mathematics teacher. 24% participants showed level I of professional competence, 44% – level II, 9% – level II; 23% participants did not pass the basic level of professional competence. The results show that the mathematics teachers have difficulties in solving mathematical, teaching, or professional problems so tailor-made retraining courses are required. The developed assessment system underlies designing the courses.

The modern education system is facing new requirements and the society is putting forward new requirements among which the leading role is to improve the professional competence of teachers of mathematical disciplines. Mathematics has been used since the time of Pythagoras as the main tool for solving various practical problems in many areas of human activity. In this regard, there is a need to improve the level of mathematical training of modern youth . We believe that the training of future teachers of mathematical disciplines should be based on the principle of integration of humanitarian and mathematical skills, as well as wider use of information technology. In our opinion, such multi-faceted training will help future mathematics teachers to develop the skills required to form a correct understanding of the essence of mathematics, its significance for other Sciences and its significance for everyday life.

The quality of teaching and teacher plays a significant role in enhancing students’ cognitive and motivational development. The purpose of this study was to identify longitudinal trajectories of student perceptions of mathematics teachers’ professional competence, and to examine how these trajectories were related to students’ engagement and achievement in mathematics and their choice of college major. The data used for analysis were obtained from the Seoul Education Longitudinal Study, a study of 2714 secondary students who were followed up for five successive years. Results showed four heterogeneous trajectories of students’ perceptions of teacher competence, and these trajectories were associated with students’ engagement and achievement in mathematics. In addition, those who consistently perceived their mathematics teachers to be highly competent and whose perceptions of their teachers’ competence became more positive over time were more likely than other students to choose math-intensive majors. These findings imply longitudinal links between mathematics teachers’ professional competence as perceived by their students and students’ choice of college major as well as their engagement and achievement in mathematics.

IntroductionThe risk of disability and mortality is high among recurrent stroke, which highlights the importance of secondary prevention measures. We aim to evaluate medication persistence for secondary prevention and the prognosis of acute ischaemic stroke or transient ischaemic attack (TIA) in China.MethodsPatients with acute ischaemic stroke or TIA from the China National Stroke Registry II were divided into 3 groups based on the percentage of persistence in secondary prevention medication classes from discharge to 3 months after onset (level I: persistence=0%, level II: 0%<persistence<100%, level III: persistence=100%). The primary outcome was recurrent stroke. The secondary outcomes included composite events (stroke, myocardial infarction or death from cardiovascular cause), all-cause death and disability (modified Rankin Scale score=3–5) from 3 months to 1 year after onset. Recurrent stroke, composite events and all-cause death were performed using Cox regression model, and disability was identified through logistic regression model using the generalised estimating equation method.Results18 344 patients with acute ischaemic stroke or TIA were included, 315 (1.7%) of whom experienced recurrent strokes. Compared with level I, the adjusted HR of recurrent stroke for level II was 0.41 (95% CI 0.31 to 0.54) and level III 0.37 (0.28 to 0.48); composite events for level II 0.41 (0.32 to 0.53) and level III 0.38 (0.30 to 0.49); all-cause death for level II 0.28 (0.23 to 0.35) and level III 0.20 (0.16–0.24). Compared with level I, the adjusted OR of disability for level II was 0.89 (0.77 to 1.03) and level III 0.82 (0.72 to 0.93).ConclusionsPersistence in secondary prevention medications, especially in all classes of medications prescribed by the physician, was associated with lower hazard of recurrent stroke, composite events, all-cause death and lower odds of disability in patients with acute ischaemic stroke or TIA.

Abstract A depth estimation procedure has been described which essentially attempts to identify depth phases by analyzing multi-station waveform data (hereafter called level II data) in various ways including deconvolution, prediction error filtering, and spectral analysis of the signals. In the absence of such observable phases, other methods based on S-P, ScS-P, and SKS-P travel times are tried to get an estimate of the source depth. The procedure was applied to waveform data collected from 31 globally distributed stations for the period between 1 and 15 October 1980. The digital data were analyzed at the temporary data center facilities of the National Defense Research Institute, Stockholm, Sweden. During this period, a total number of 162 events in the magnitude range 3.5 to 6.2 were defined by analyzing first arrival time data (hereafter called level I data) alone. For 120 of these events, it was possible to estimate depths using the present procedure. The applicability of the procedure was found to be 100 per cent for the events with mb &gt; 4.8 and 88 per cent for the events with mb &gt; 4. A comparison of level I depths and level II depths (the depths as obtained from level I and level II data, respectively) with that of the United States Geological Survey estimates indicated that it will be necessary to have at least one local station (Δ &lt; 10°) among the level I data to obtain reasonable depth estimates from such data alone. Further, it has been shown that S wave travel times could be successfully utilized for the estimation of source depth.

This study has developed a digital mathematics handbook that helps students to strengthen their mathematical skills at the elementary level of education. A survey of mathematics teachers collected data. In developing an integration manual on technology based on a survey of the state of technological integration in schools, it employed a research and development (RD) approach. A number of 24 teachers participated in the material creation. The multimedia materials produced during the trial were developed and used. Participants consisted of primary learning children. Results have shown that the trainers' preferred theory is undergraduate, and most of them have a poor capacity to integrate creativity into a research analysis. In the presentation of the under-graduates in mathematics the material produced was extremely good.

Introduction. Objective and regular students’ knowledge monitoring in technical subjects can be implemented by means of special tests allowing for the required mastering level of the matter and the reliable consolidation of the acquired knowledge. Various aspects of the application of tests in the academic activity were considered. Materials and methods. Tests used in practical studies should meet specific requirements, such as: validity, definiteness, simplicity, unambiguity, reliability. The identification of mastering levels makes it possible to “troubleshoot” and to improve the academic activity and the mastering degree of the competences by the students. Based on the assessment of the studying pattern of the forthcoming activity, one could point out four mastering levels of the subject matter. Level I tests include recognition, discrimination and classification. Level II tests monitor the mastering of the subject in the level of “reproduction” allowing for retrieval of information from the memory and its analysis, for routine assignment solutions. Level III tests impose special assignments challenging a student with quests for which no ready algorithms are catered, whereas the solutions found lead to obtaining of subjectively new information. Level IV tests reveal students’ capability to take decisions in new problematic situations, the solutions found, being a result of creative activity, are followed by obtaining of objectively new information. Results. To establish an efficient system of monitoring tests in a certain subject, a number of basic prerequisites is required, such as a data base, a sample group of with the required number of assignments, at least 30 and maximum 70, a time limit in accordance with the required labor intensity, assessment of the assignments and its criteria, the output of the results. Conclusions. If there is a required number of computers of at least one PC per two students, correctly arranged computer testing considerably reduces time demand of a monitoring event, increases the responsibility and the progress of the students, guarantees the objectiveness of the knowledge monitoring and helps to avoid conflicts.
