Out-of-school environments offer a unique opportunity for experiental learning which transcends the role of educational resources and teachers. This article introduces the special topic of out-of-school learning in science and mathematics education. First, we present the theoretical underpinnings from the movement towards crossing the boundaries of school in educational practices and broadening educational spaces. We continue with the key facets of out-of-school learning through a constructivist approach, aided by the concept of mediation environments as the third educator from a socio-material perspective. Furthermore, we focus our discussion on a selection of articles from this special number as an international overview on out-of-school learning. In the conclusion section, we discuss the gaps that the following works fill, as well as new questions that arise in the area. The closing remarks highlight the promotion of active learning in students, considering the role of the environment as the third educator.

Electron Shells

The article contains a hypothesis on the dominance of chemical elements of top periods of the Periodic Table in living matter. The idea is that the elements of the third and next periods of the table, in contrast to the first two periods, have larger number of subvalent electron shells. Because of this, ionization of the k-electron shell by radiation (kosmic and terrestrial) in the heavy atoms always leads to the Auger cascade, which causes the destruction of molecular chains. This mechanism can play a role of the radiation filter in the selection of light chemical elements in living matter in addition to the mechanism of hydrolytic filter (G.R. Ivanitskii).

The study includes four chapters, the first is devoted to reviewing the research problem, its importance, objectives and limitations in addition to defining terms. The second chapter contains the theoretical introduction that includes a definition of optical art and its impact on highlighting features of urbanidentity. The third chapter examines several models in optical formation, where several architectural designs were discussed by its role in highlighting the features of urbanidentity. The fourth chapter includes the results and observations of the role of art and opticalformation in highlighting the urbanidentity. This is because it adds an aesthetic touch and an expression of various creative and unfamiliar ideas to the designer in a waythat occurs a fundamental change in the fixed rules of the viewer and his/her expectations for designs where the creative touch is in the overlay, communication, separation, penetration, segmentation of shapes and colors, and selection of materials needed to implement these designs have the biggest role in highlighting the features of urbanidentity. Where we found that the optical formation of its various types is the main component of architecture that it boasts of, and with what it contains creative ideas that express the reality of urbanidentity.

The paper deals with the problems while planning the application of method of observation as the primary method for data collection. These include determining the objectives, theoretical and operational elaboration of the research plan and collection of initial evidence from other sources of data that can be used to successfully plan research mainly based on observation. In the first section of the paper it is pointed to the unjustified overemphasis of differences between participatory and non-participatory forms of observation in its planning. The second section shows the possibility of its application to other sources and methods of data collection when planning observations. Special attention is paid to the role of interview and sequential analysis. In the third section, the issues of preparing data analysis in the planning of observation are specifically discussed. The fourth section shows the specificity of the planning of observation, depending on the nature of the data. We also considered the concretization of the plan of observation, including the selection of size, location and time for performing monitoring and positioning one or more observers. The fifth section briefly points to some suggestions about training observers. The concluding section of the paper deals with planning during the observations, with emphasis on grounded theory.

The article reveals the role of equations at the basic and profi le levels of teaching students mathematics at school. Various ways of solving rational equations of the third and fourth degree, based on the technique of the introduction of a new variable, are demonstrated. This technique is universal in mathematics. It fi nds its application both in algebra, in the solution of inequalities, in equations and their systems, and in geometry, where the additionally constructed geometric fi gure — a segment, an angle, a circle, a triangle — appears as a new variable. The methods of solving rational equations, shown by the author in this article, will be especially useful and interesting for students of profi le classes, as well as for applicants and students of higher educational institutions and mathematics teachers.

As computer literacy and programming ability increase at the elementary and junior high school levels, more thought must be given to the role of computers in mathematics learning. One step to be taken at the high school level is to accept Gerald Rising's (1983) suggestion to separate computer science and mathematics. This proposal is an excellent one and would help us to focus on ways to improve mathematics learning through the use of computers.

Abstract Members of the H-NS protein family play a role both in the chromosome architecture and in the regulation of gene expression in bacteria. The genomes of the enterobacteria encode an H-NS paralogue, the StpA protein. StpA displays specific regulatory properties and provides a molecular backup for H-NS. Some enterobacteria also encode third H-NS paralogues. This is the case of the enteroaggregative E. coli (EAEC) strain 042, which encodes the hns, stpA and hns2 genes. We provide in this paper novel information about the role of the H-NS2 protein in strain 042. A C > T transition in the hns2 promoter leading to increased H-NS2 expression is readily selected in hns mutants. Increased H-NS2 expression partially compensates for H-NS loss. H-NS2 levels are critical for the strain 042 fitness. Under some circumstances, high H-NS2 expression levels dictated by the mutant hns2 promoter can be deleterious. The selection of T > C revertants or of clones harboring insertional inactivations of the hns2 gene can then occur. Temperature also plays a relevant role in the H-NS2 regulatory activity. At 37 °C, H-NS2 targets a subset of the H-NS repressed genes contributing to their silencing. When temperature drops to 25 °C, the repressory ability of H-NS2 is significantly reduced. At low temperature, H-NS plays the main repressory role.

Background: In recent years interest has increased in the role of out-of-school learning (OSL) in improving science education and students’ motivation toward learning. In Hungary, however, little is known about the practice and outlook of OSL. Purpose: This study explored (a) how Hungarian primary schools use OSL places (including the location, frequency, and motivation of the visits), (b) the overall attitudes toward OSL, and (c) whether any obstacles to OSL exist that schools need to overcome. Methodology/Approach: We used a large-scale online survey collecting data from a total of 4,861 respondents, which identified the parameters of OSL programs organized by primary schools. Findings/Conclusions: Results reveal that schools follow the recommendations of the National Core Curriculum on OSL, but such programs only occasionally take place, even though the majority of respondents expressed the desire for increased frequency. The main reasons for the low prevalence of OSL activities are difficulties with financial arrangements and fitting them into the syllabus. Implications: Further research should focus on how to overcome barriers to OSL to take the intention of the respondents into consideration.
