The purpose of the article is to put forward English monologue production assessment criteria to verify the efficiency of the devised methodology of teaching English for future mechanical engineers. In the course of the research, theoretical, empirical, and statistical methods have been used. Various approaches to identifying the assessment criteria have been thoroughly analyzed. Seven criteria to assess the monologue production skills, five primary and two secondary ones, have been suggested. The allocation of the points by every criterion according to the devised scales have been elucidated. The proposed assessment criteria were used in the methodological experiment that was held at Igor Sikorsky Kyiv National Technical University. The experiment in question aimed to verify the efficiency of the devised methodology of teaching English monologue production to students majoring in mechanical engineering. Three experimental groups, 34 students in total, studying in their final year of Bachelor studies within the Subject Areas of Applied Mechanics and Industrial Engineering, participated in the methodological experiment. The conducted experiment confirmed the efficiency of the methodology proposed.

This paper studies the effect of laboratory activities on the results obtained by the students on 7 core curricular units (CUs) of an Integrated Master in Mechanical Engineering. Each CU is characterized by means of 4 performance indices, over the 6-year period 2014/2015–2019/2020. Firstly, individual indices in a per semester basis are compared. Secondly, the CUs are regarded as objects defined in a 4-dimensional space of features, and the multidimensional scaling (MDS) technique is adopted for clustering and computer visualization. The MDS is powerful for analyzing the multivariate dataset, unveiling patterns not perceived by standard statistical methods.

This review paper deals with the use of statistical methods to evaluate systematic and random errors associated with trigonometric parallaxes. First, systematic errors which arise when using trigonometric parallaxes to calibrate luminosity systems are discussed. Next, determination of the external errors of parallax measurement are reviewed. Observatory corrections are discussed. Schilt’s point, that as the causes of these systematic differences between observatories are not known the computed corrections can not be applied appropriately, is emphasized. However, modern parallax work is sufficiently accurate that it is necessary to determine observatory corrections if full use is to be made of the potential precision of the data. To this end, it is suggested that a prior experimental design is required. Past experience has shown that accidental overlap of observing programs will not suffice to determine observatory corrections which are meaningful.
