AbstractRational number knowledge is a crucial feature of primary school mathematics that predicts students’ later mathematics achievement. Many students struggle with the transition from natural number to rational number reasoning, so novel pedagogical approaches to support the development of rational number knowledge are valuable to mathematics educators worldwide. Digital game-based learning environments may support a wide range of mathematics skills. NanoRoboMath, a digital game-based learning environment, was developed to enhance students’ conceptual and adaptive rational number knowledge. In this paper, we tested the effectiveness of a preliminary version of the game with fifth and sixth grade primary school students (N = 195) using a quasi-experimental design. A small positive effect of playing the NanoRoboMath game on students’ rational number conceptual knowledge was observed. Students’ overall game performance was related to learning outcomes concerning their adaptive rational number knowledge and understanding of rational number representations and operations.

For many decades there has been a consensus among linguists of various schools that derivational suffixes function not only to determine the word-class of the complex expressions they form, but also convey semantic information. The aspect of suffix-inherent meaning is ignored by representatives of a relatively new theoretical direction – Neo-Construction Grammar – who consider derivational suffixes to be either purely functional elements of the grammar or meaningless phonological realizations of abstract grammatical morphemes. The latter view is maintained by adherents of Distributed Morphology, who at the same time emphasize the importance of conceptual knowledge for derivational processes without attempting to define this aspect. The purpose of this study is first of all to provide support for the long-standing assumption that suffixes are inherently meaningful. The focus of interest is on the suffixes -ship, -dom and -hood. Data from Old English and Modern English (including neologisms) will show that these suffixes have developed rich arrays of meaning which cannot be structurally derived. Moreover, since conceptual knowledge is indeed an important factor for word-formation processes, a concrete, theory-independent model for the representation of the synchronically observable meaning components associated with -ship, -dom and -hood will be proposed.

Abstract Asking first about how the lexical meaning manifests itself as we experience it in a communicative event, the author explores the background of the ways in which we are able to perceive the meaning of words in texts. One useful way of thinking about how recipients react to the words in utterances is in terms of behavioural and actional lexical meaning. The first refers to the understanding of meaning, the second corresponds to interpretations of words when the recipient does not succeed in the process of natural understanding of words. These terms lead to questions about the rationality of language. One aspect of this rationality is the function of the intentional­emergent mechanism that adjusts the interplay of automatic and deliberate use of language. This mechanism has its roots in the fundamental human nature: we are behavioural­actional beings. Pragmatic analysis sheds light on how hearers understand and interpret what they hear with regard to their conceptual knowledge associated with words.

The Military

The task of choosing the rational number of power structures is always one of the main priorities of any political leadership of the state. An insufficient number of armed forces is a threat to the national security of the state; an excess number creates pressures on the development of the country's national economy. Today, when the development programs of the Armed Forces of Ukraine are being formed in the context of the practical application of their units and subunits to carry out combat missions, questions of choosing a priority approach to the formation (justification) of the rational size of the Armed Forces of Ukraine is an urgent issue. The article proposes a structure for conducting research on the development and implementation of the methodology of military-economic substantiation of the rational strength of the Armed Forces of Ukraine in the system of defense planning of Ukraine in the formation of programs for their development for the medium and long term. The main objectives of this methodology are: scientific substantiation of the range of the necessary strength of the Armed Forces of Ukraine for the period of the program of their development; the choice of the indicator of the rational size of the Armed Forces of Ukraine according to the years of the program from a certain range of its changes; military-economic substantiation of this number under the influence of various limiting factors. The development and implementation of such a methodology will increase the efficiency of the formation and implementation of development programs of the Armed Forces of Ukraine, as well as the efficiency of using public funds for the development of power structures.
