Abstract

The aim of this research was to determine whether teaching mathematics in an interesting way has an effect on increasing motivation and success of high school students. With this purpose, an experimental research was carried out with comparative groups in high schools in Čitluk, Ljubuški and Mostar on a sample of 300 students. Interesting teaching methods were utilised with students in the experimental group, while the control group worked in a traditional way. The survey questionnaire and the test of knowledge served as measuring instruments. Testing was performed at the beginning and at the end of the study. Lykert-type scale was used to test internal motivation while statistical significance of statistical significance of differences was measured using the mixed ANOVA model 2x2 and t- test. The results show a better effect of interesting teaching on the success of students, as well as an increase in students’ motivation to learn mathematics. Therefore, it is recommended to apply interesting methods in teaching mathematics., Cilj je ovoga istraživanja utvrditi postoji li povezanost zanimljive nastave matematike i povećanja motivacije i uspjeha učenika srednjih škola. S tom je svrhom provedeno eksperimentalno istraživanje s usporednim skupinama u srednjim školama u Čitluku, Ljubuškom i Mostaru na uzorku od 300 učenika. U radu s učenicima eksperimentalne skupine primjenjene su zanimljive nastavne metode i oblici rada, dok je kontrolna skupina radila na tradicionalan način. Kao mjerne instrumente koristili smo anketni upitnik i test znanja. Testiranje smo proveli na početku i na kraju istraživanja. Ispitivanje unutarnje motivacije izvršeno je putem skale Likertova tipa, a testiranje statističke značajnosti razlika pomoću Anove mixed model 2 x 2 i t-testa. Rezultati pokazuju bolji učinak zanimljive nastave na uspjeh učenika, kao i na povećanje motivacije učenika za učenje matematike. Zbog toga se preporučuje primjena zanimljivih načina rada u nastavi matematike.

5. Physical Preconception of Primary Education Pupils

Author

Abstract

During their preschool age children discover natural phenomena in their environment. In their consciousness, they form the basic physical concepts based on experience. Their ideas can be right, but they can also be wrong because they take into consideration only what they see and thus, they come up with wrong ideas or misconceptions. At the very beginning of their primary education, teachers of class teaching directly witness their ideas related to basic physical concepts through various subjects: mathematics, natural sciences, art and physical education. Frequently, neither teachers nor their pupils consider these notions, thus their wrong ideas remain firmly rooted and present a barrier to the adoption of the correct physical ideas. Research of basic concepts related to motion, space and time was carried out as part of the workshop Class Teaching Course Open Days at the Faculty of Natural Sciences, Mathematics and Education of the University of Mostar. The sample consisted of pupils of primary education of Herzegovina-Neretva and West-Herzegovinian Cantons. It has shown that pupils have the correct ideas about many physical phenomena, but it has also shown the presence of intuitive ideas which are not in accordance with physical ideas and need to be corrected in time

Abstract

Testiranje na prisutnost gospodarski značajnih virusa obavljeno je u pokusnom matičnom nasadu drvenastih indikatora Zavoda za fitopatologiju Agronomskog fakulteta u Zagrebu. Nasad sadrži pet vrsta indikatorskih biljaka (110 Richter, LN33, Kober 5BB, Vitis riparia Gloire de Montpellier, Vitis rupestris St. George). Prikupljanje materijala i testiranje obavljeno je tijekom siječnja 2011. godine. Metodom ELISA testirano je po 15 biljaka svake indikatorske vrste na devet virusa: virus mozaika gušarke (ArMV), virus lepezastog lista vinove loze (GFLV), uvijenosti lista vinove loze pridruženi virus 1, 2, 3 i 7 (GLRaV-1, GLRaV-2, GLRaV-3 i GLRaV-7), A-virus vinove loze (GVA), B-virus vinove loze (GVB) i virus pjegavosti vinove loze (GFkV). Od ukupno 75 uzoraka zaraženih je bilo 8 (10.7 %) biljaka. Od toga ArMV pronađen je kod 6 uzoraka (u jednoj biljci 110 Richter i V. rupestris te u po dvije biljke LN33 i Kober 5BB), pa je time bio i najdominantniji, GLRaV- 1 pronađen je u jednom uzorku V. rupestris kao i GLRaV-2 u uzorku V. riparia. Iz navedenih rezultata moguće je da je do zaraze sa ArMV došlo putem vektorskih nematoda (Xiphinema diversicaudatum), sa GLRaV-1 putem štitastih uši sa obližnjih biljaka, dok je GLRaV-2 vjerojatno u nasad došao zaraženim sadnim materijalom. U cilju prevencije širenja zaražene biljke su odstranjene mehaničkim putem, a ostatci njihovog korijenovog sustava uništeni su glifosatom.

Abstract

The presence of eight viruses (Arabis mosaic virus ArMV, Grapevine fanleaf virus GFLV, Grapevine fleck virus GFkV, Grapevine leafroll- associated viruses 1, 2 and 3 - GLRaV-1, - 2, and -3, Grapevine virus A GVA, Grapevine virus B GVB) was tested using ELISA in a collection of woody indicator vines located at the Faculty of Agriculture Zagreb. Out of 75 tested plants (15 from each indicator - LN33, 110 Richter, Vitis riparia Gloire de Montpellier, V. rupestris St. George and Kober 5BB) six of them (one of 110R and V. rupestris, two of LN33 and Kober 5BB) were positive to ArMV, one V. rupestris to GLRaV- 1 and one V. riparia to GLRaV-2. All the infected plants were cut off and their roots killed using glyphosate.

10. Suradničko učenje kao motivacija učenika za učenje matematike.

Abstract

Man is a social being and cooperates with other people. Likewise, students must cooperate with each other so that they can easily learn the prescribed mathematical background. Collaborative learning, which is increasingly represented in teaching practice, has many advantages over traditional teaching in math classes. It is based on the idea that students will be quicker and easier to understand and adopt abstract mathematical concepts and rules, and to solve mathematical tasks faster and more effectively if they talk to each other about them. Many studies have shown that they are particularly motivated when they collaborate in learning. This is confirmed by our research. The research was conducted at the High School in Čitluk. The students were divided into two groups, both control and experimental. The control group has learned in the traditional way, and experimental has used collaborative learning. The results showed that the students of the experimental group were more motivated to learn from the student control group. [ABSTRACT FROM AUTHOR]
