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 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.
