20.500.12556/DKUM-20770 NAMEMBNOST IN VARNA UPORABA IZBRANIH NAPRAV V ŠOLSKIH KEMIJSKIH LABORATORIJIH THE INTENDED FUNCTION AND SAFE USAGE OF THE CHOSEN INSTRUMENTS IN THE SCHOOL CHEMISTRY LABORATORIES Eksperimentalno delo v šolskih kemijskih laboratorijih je ključna metoda poučevanja in učenja na stopnji osnovnega in srednjega kemijskega izobraževanja (Sikošek, b.l.). Učenci/dijaki med eksperimentiranjem uporabljajo različne, vendar enostavne naprave in laboratorijsko opremo, ki jim omogoča primerjalno opazovanje in merjenje pojavov, s tem pa razvijajo eksperimentalni pristop (Vrtačnik, M. in sodelavci, 2000). Katere naprave za eksperimentiranje pri pouku kemije naj posedujejo osnovne in srednje šole, je predpisano v virih »Priporočena učila za devetletno osnovno šolo« in »Standardi in normativi opremljenosti pri pouku kemije«. V diplomskem delu sem se osredotočila na predstavitev uporabnosti šestih sodobnejših naprav iz opreme šolskih kemijskih laboratorijev (centrifuga, elektronska analizna in elektronska precizna tehtnica, konduktometer, laboratorijski pH meter in vodotesni pH meter in termometer) in štirih sodobnejših nadstandardnih naprav, katerih prisotnost v šolskih kemijskih laboratorijih bi ob ustrezni uporabi omogočila kakovostnejšo in enostavnejšo izvedbo nekaterih eksperimentov, predvidenih v učnih načrtih (elektronsko palično mešalo, Kippov aparat, membranska vakuumska črpalka in rotavapor). Ker morajo biti izobraževalne ustanove varno delovno mesto in učno okolje (»Varnost in zdravje pri delu v šolstvu«, b.l.), sem se osredotočila tudi na varnostni vidik uporabe vseh desetih izbranih naprav. The experimental work within school chemistry laboratories certainly represents one of key methods of teaching and learning at the elementary and high-school level of education in the field of chemistry (Sikošek, b.l.). By conducting experiments, the pupils and students develop various techniques of experimental approch, using different simple instruments and laboratory equipment that enable them to measure and observe numerous phenomena (Vrtačnik et. al., 2000). The range of instruments required for experimental work at every elementary and high school is defined in handbooks »Recommended teaching instruments for nine-year elementary school« and »Standards and normatives concerning the equipment used for chemistry education«. In my diploma I focused mainly on representation of practical usage regarding six modern instruments that are considered as required inventory of teaching equipment (centrifuge, analytical balance, precision balance, conductivity meter, laboratory pH meter and waterproof pH meter and temperature meter), together with four modern high-standard devices that would surely contribute to the simplification and quality of some experiments which are foreseen in the present curricula (electronic bar blender, Kipp's apparatus, vacuum membrane pump and evaporator). Educational institutions are also supposed to include a safe working and teaching environment. For that reason, I also provided an evaluation of safety concerning the usage of all ten instruments/devices. šolski kemijski laboratorij laboratorijske naprave varnost uporaba school chemistry laboratory laboratory instruments and devices safety usage true true false [I.
