Abstract

Abstract:- The paper presents significant developmental aspects of the students’ science experimental skills in scienceeducation. Science experimental skills are briefly described and classified. Authors put the accent on the structure ofregulation phases within acquiring of science experimental skills. Experimental skills go through quite rapid developmentwithin students’ school attendance from the primary up to secondary school. The aim of research is level measuring ofacquiring these skills during students’ experimental skills development.Students in primary school are not able to reach all developmental stages. All developmental stages of acquiring scienceexperimental skills are achieved by students at first on upper secondary school. Results are presented as exemplified byconcrete science experimental skill: observation and measuring of temperature. The presentation is supplemented by originalscience experiments.Keywords: Science Experimental Skills, Acquiring Of Science Experimental Skills, Development.
