Povzetek
Pozivamo bralce, da poskusijo izvesti poskuse in sestaviti sklop opreme, ki se lahko uporablja v večini poskusov. Ustvarjanje zabojnikov z vsemi materali za skupine dijakov je najbolj koristen način za dokumentiranje vsega, kar lahko posameznik naredi z LED. Potem, ko dijaki začnejo delati z LED, se jim bodo porajala lastna vprašanja in bodo oblikovali svoje lastne poskuse. V prihodnjih prispevkih bomo ocenjevali specifične poskuse in njihovo pedagoško obravnavo v skladu z navodili, ki temeljijo na učenju z raziskovanjem. Prav tako bomo poskrbeli za zaporedje navodil s podpornimi vprašanji, ki bodo vašim dijakom omogočili opazovanje pojava, njegovo analiziraje in predlaganje več razlag za mehanizem ter na koncu testiranje teh pojasnil in nove poskuse.
Abstract
Light-Emitting Diodes: A Hidden Treasure
We invite readers to try the experiments and assemble a set of equipment that can be used in most of the experiments. Creating containers with all of the materials for groups of students is the most helpful way to keep track of everything that one can do with LEDs. Once students start working with the LEDs, they will generate their own questions and design their own experiments. In future papers we will elaborate on the specific experiments and their pedagogical treatment consistent with inquiry-based instruction.
We will provide instructional sequences with supporting questions that will allow your students to observe a phenomenon, to analyze it and propose multiple explanations for the mechanism, and finally test those explanations in new experiment
