The effect of japanese knotweed extracts on the growth of radish roots
The Japanese knotweed (Fallopia japonica) is nowadays in Europe known as a strongly invasive alien plant species. Its dissemination success is related with the effect of the secondary metabolites which are released to the soil by the plant. So-called alelopatic compounds can be found in the leaves and roots or also in other parts of the Japanese knotweed. The alelopatic effect is mostly noticeable as an inhibition of the germination and as growth of the roots and shoots of the close growing plants. The inhibition of the roots growth can be related to the reduced number of the cell division in the root tips.
In this dissertation we tried to discover how the leaf and the root extract of the Japanese knotweed have an impact on the root growth and the cellular division in the root tip of the radish. The seeds of the radish were watered with 5 % extract of the leaves and roots of the Japanese knotweed. From the third to the seventh day of the sprouting we made notes on the germination of the seeds and the length of the roots of the cotyledons. We fixed the root tips and prepared the specimen with coloured genetic material. We counted the number of the divided and undivided cells of the root tip under the microscope. We expressed the proportion with the mitotic index. The results were compared with the t-test.
The seeds, treated with the extract of the leaves of the Japanese knotweed, germinated with a delay. The length of the roots of the treated cotyledons was shorter than the length of the control cotyledons wherein the leaf extract decelerated the growth of the roots with more strength than the root extract. Adding of the leaf and root extract of the Japanese knotweed resulted as a lower mitotic index in the root tip of the radish
Rastline na šolskem vrtu : koledar gojenja rastlin
S koledarjem za gojenje rastlin na šolskem vrtu želimo
optimizirati uporabo šolskega vrta. Nastal je v
okviru internega projekta Herbarij in šolski vrt v izobraževanju
učiteljev, ki je potekal na Pedagoški fakulteti
v Ljubljani. Koledar je pripomoček za načrtovanje
šolskega vrta, ki učitelju podaja napotke za gojenje
rastlin ter ponuja predloge njihove uporabe pri pouku
o bioloških vsebinah. Prilagojen je za podnebne razmere
v osrednji Sloveniji ter odgovarja na učne cilje, ki
so zapisani v učnih načrtih.

Žuželke- delavnice za otroke
Prispevek je rezultat projekta z naslovom Promocija biotske pestrosti v Krajinskem
parku Kolpa (PRO-BIO-KOLPA), pri katerem so sodelovale institucije: Univerza v Ljubljani,
Pedagoška fakulteta in Fakulteta za računalništvo in informatiko, KOLPA\u27S podjetje za
proizvodnjo, trgovino, gostinstvo in servis, d. o. o., in Javni zavod Krajinski park Kolpa. Projekt
je potekal od marca do julija 2017. S projektom smo želeli izboljšati ozaveščenost mladih o
metuljih in žuželkah na splošno.
Na osnovni šoli in v Krajinskem parku Kolpa smo izvedli različne delavnice o žuželkah. Otroci
in mladostniki so se učili rokovanja z žuželkami ter raznolikost metuljev spoznavali med
lovljenjem metuljev na terenu. Izvedli smo delavnice o obustnih aparatih žuželk, o razvojnem
krogu metuljev, o zgradbi metuljev, simetriji kril ter o raznolikosti žuželk

Use of augmented reality for teaching human anatomy
One of the key areas for realizing the aims of higher digital literacy as the driving force of
contemporary society of 21th century is the educational area, which strives for developing new open
learning environments and pedagogical strategies, based on the use of information and communication
technology in the process of teaching and learning. The purpose of the article is to introduce designed
teaching materials for learning human anatomy in primary school – structure and activity of the heart,
which include the use of new technology – augmented reality, using mobile application Mirage AR9.
Within the research we tested formed teaching materials among seventh and eighth grade students in
primary school. We investigated students’ knowledge about the topic before and after performing
lesson, to establish the effects of teaching materials application. We also wanted to measure the
interest of learning with the teaching materials. Analyse of the results indicate statistically significant
better knowledge among students after conquering new subject matter using mobile application.
Students also expressed high interest in this sort of learning. Results of the research advertise
guidelines for implementation of used technology in educational process
Use of augmented reality for teaching human anatomy
Eno ključnih področij za uresničevanje ciljev višje digitalne pismenosti, kot gonilo razvoja sodobne
družbe 21. stoletja, je področje vzgoje in izobraževanja, ki si prizadeva za razvoj odprtih učnih okolij
in pedagoških strategij, ki bi v polni meri izkoristile možnost uporabe IKT tako v procesu učenja kot
poučevanja. V okviru prispevka želimo predstaviti oblikovana učna gradiva za pouk anatomije človeka
v osnovni šoli – zgradba in delovanje srca, ki vključujejo uporabo novih tehnologij – obogatena
resničnost s pomočjo aplikacije Mirage AR9. Zasnovana učna gradiva smo testirali na učencih
sedmega in osmega razreda. Znanje učencev o izbrani temi smo preverjali pred in po izvedeni učni uri,
da bi ugotovili učinke uporabe razvitih učnih gradiv na znanje učencev. Izmeriti smo želeli tudi interes
za učenje z izbranimi gradivi. Analize rezultatov so pokazale, da so učenci pri osvajanju nove učne
snovi z uporabo aplikacije osvojili statistično pomembno boljše znanje. Učenci so izrazili velik interes
za tovrsten način učenja. Rezultati raziskave dajejo smernice za implementacijo uporabljene
tehnologije v vzgojno-izobraževalni proces.One of the key areas for realizing the aims of higher digital literacy as the driving force of
