Manuscripts submitted to this journal are considered if they have been submitted only to it, they have not been published already, nor are they under consideration for publication or in press elsewhere. Contributions to the Bulgarian Journal of Science Education must report original research and will be subjected to review by anonymous and independent referees at the discretion of the Editor(s).

Manuscripts for consideration should be sent electronically to toshev@chem.uni-sofia.bg Electronic submissions should be sent as email attachments using a standard word processing program. If email submission is not possible, please send an electronic version on disk.


Manuscript preparation

General guidelines

(i)                 Manuscripts can be presented in Bulgarian or in English.

(ii)               Manuscripts should be compiled in the following order: title of the paper (informative without any abbreviations); names of the authors (without their current academic positions); abstract in size not exceeding 20 lines; 3-6 keywords (only in English); full text; acknowledgments; appendixes (as appropriate); notes; references; full addresses of all authors (academic positions, affiliations, postal addresses, email addresses).

(iii)             Figures and their captions are to be presented separate to text but their position in the text must be indicated (Fig. 1, Fig. 2, etc.). Please do not embed figures in the paper file.

(iv)             Tables and their captions are to be presented separate to text but their position in the text must be indicated (Table 1, Table 2, etc.). Please do not embed tables in the paper file. It is expected the tables contain values of some quantities or variables; the text tables are not encouraged.



Notes and References

The references should be cited in Roman script. If there are sources in Cyrillic script, they (authors, titles and sources) should be presented in Roman script with translation into English or by transliteration.

The list of references includes sources which can be easily checked by the referees and by the readers as well. The marginal sources without world visibility should not be included in the list of references. Nevertheless, if such sources are necessary to be cited, they should be put in the list of notes. This list should contain some additional explanations or marginal sources including internet addresses, preferably in portable document format (pdf). The position of notes within the text is marked by Arabic numerals as superscripts.

Style of the list of references should conform to that of Publication Manual of American Psychological Association (APA style), widely used for such kind of publications.

Last words

            The acceptance of the submitted manuscripts for publication depends strongly on the reviewers’ recommendations.
