TRENDS IN SCIENCE EDUCATION RESEARCH: A CONTENT ANALYSIS OF BULGARIAN EDUCATIONAL JOURNALS FROM 2011 TO 2015

The primary objective of this study is to outline the trends in science education research based on content analyses of publications from 2011 to 2015 in four Bulgarian educational journals: “Chemistry: Bulgarian Journal of Science Education”, “Strategies for...

USE OF VECTORS AND FACTORIALS FOR CALCULATION OF MICROSTATES FROM \(\mathbf{P}^{\mathbf{2}}, \mathbf{D}^{\mathbf{2}}, \mathbf{F}^{\mathbf{2}}\) CONFIGURATIONS AND DESCRIPTION OF THE \(\mathbf{P}^{\mathbf{2}}\) ELECTRON CONFIGURATION

The aim of this research was to compute the number of microstates for \(\mathrm{p}^{2}\) configuration \(n=6\) an d \(x=2\), for \(\mathrm{d}^{2}\) configuration \(n=10\) an d \(x=2\) and \(\mathrm{f}^{2}\) configuration \(n=14\) an d \(x=2\) using vector...

DETERMINATION OF THE RATE AND THE EQUILIBRIUM CONSTANT WITH KINETIC APPROACH

So far, the kinetic approach for determination of the rate constants of reversible reaction is still using the equilibrium concentration. Basically, this is thermodynamic concept. This technique is not only needs a long time for the experiments but also gi...

STUDY OF THE APPROPRIATION BY THE PUPILS OF SECOND BACCALAUREATE YEAR OF KNOWLEDGE OBJECTS RELATING TO ACID-BASES TITRATIONS

This article aims to study the difficulties of the Moroccan high school pupils in teaching of the acid-base topic. Based on others similar context, particularly the Tunisian one, we have firstly carried out a classification of the knowledge objects relating...

COLLEGE STUDENTS’ CONCEPTIONS OF NEWTONIAN MECHANICS: A CASE OF SURABAYA STATE UNIVERSITY INDONESIA¹⁾

Students’ understanding of scientific phenomena have been of considerable interest to science education researchers. However, students’ conceptions might differ from those generally accepted by researchers as scientific concepts. This study was possessed the c...

ESTIMATION OF IGNITION TEMPERATURE FOR TWO KINDS OF ENERGETIC MATERIALS BY THERMAL ANALYSIS AND KINETIC EVALUATIONS

Some kind of energetic materials are substantially unstable and decompose slowly during their storage at room temperatures. Decomposition releases heat and gases which cause decomposition processes was accelerated. This process reduces performance and storag...

SPECTROSCOPIC STUDIES ON A POTENTIAL COMPLEX BETWEEN TNT AND FOLIC ACID: A DFT STUDY

The interaction between TNT and an indispensably substantial biological molecule, folic acid (FA), has been investigated at the level of density functional theory. Two models are assembled: (i) an intimate pair of TNT and FA and (ii) π-complex of them. Th...
