The Internet is a service where much information from the world of science, technology, fashion and entertainment can be found. With the development of mobile devices, information from the Internet ...has become available almost everywhere. This fact should be used to help students learn curriculum e-materials from smartphones, tablets and netbooks. One of the Internet services that can be successfully applied in teaching is a blog. This research has analyzed the effects of using blog as a web tool in biology teaching. The sample under research included 171 students divided into two groups: an experimental group which used a blog and a control group in which the teaching was conducted without a blog as a teaching tool. The students from both groups were first tested by means of a pre-test according to which the groups were at the same level of knowledge of biology and after covering the topic of Cytology both groups did the post-test. The research showed that the students who used the blog had statistically a significantly better result on the post-test. Further research showed that students make equal progress at all levels of knowledge with the help of blogs and that the blog is the most useful to advanced students.
The Flipped Classroom (FC) is a teaching approach in which students gain the first-exposure learning with online materials outside the classroom, and then, in the classroom, they focus on interactive ...or engaging exercises. Despite its considerable publicity, the studies focused on the FC in primary education are deficient. The aim of this research is to determine efficiency and students’ involvement in the flipped Biology classroom in primary school, compared to the conventional classroom (CC) approach. Educational efficiency and students’ involvement are measured by combining the values of the students’ performance and mental effort on the test. Each task in the test was followed by the 5-point Likert scale for evaluation of invested mental effort. The total sample of this research included 112 students, aged from 12 to 13. The results show that the FC approach contributes to the reduction of the students’ mental effort and an increase in the students’ performance. On the basis of calculated efficiency and students’ involvement of applied teaching approaches, it was concluded that the FC represents a feasible and efficient approach to Biology primary education.
Research studies aimed at finding a more efficient model of teaching biology are still sporadic and inconsistent in the contemporary literature. The main aim of the research was to examine the ...correlation between the application of teaching strategies in biology teaching and students' school achievements, depending on how much the teacher respects their learning styles. The method of theoretical analysis and descriptive method were applied in the research. The sample consisted of 151 third-grade students (39.7% male and 60.3% female) of upper-secondary school. Kolb’s Inventory of Learning Styles and Questionnaire for Assessing the Teaching Strategies of Biology Teachers were used as data gathering tools. Independent t-test, χ2 - square test, and One-way analysis of variance (ANOVA) were used to analyze data. The results showed that there was a statistically significant correlation between teaching strategies, learning styles, and students' school achievement in biology learning. At the same time, students perceived the applied teaching strategies differently, and manifested different dimensions of learning styles. This was followed by the conclusion that students achieved better school achievements in biology teaching when they were taught in the ways that corresponded to their learning styles, which pointed to certain implications for inquiry-based teaching, as well as in education of future biology teachers.
U radu se prikazuje komparativna analiza učinkovitosti upotrebe edukativnog računalnog programa i tradicionalnih nastavnih metoda u nastavi biologije u srednjoj školi. Stratificirani slučajni uzorak ...sastojao se od 173 učenika 12. razreda srednje škole u Zrenjaninu u Srbiji, a koji su bili nasumično svrstani u kontrolnu i eksperimentalnu skupinu. Učenici u eksperimentalnoj skupini učili su nastavne sadržaje biologije („Mehanizmi nasljeđivanja“) uz pomoć edukativnog računalnog programa, a učenici u kontrolnoj skupini učili su iste sadržaje primjenom tradicionalnih nastavnih metoda. Istraživanje je provedeno s pomoću istraživačkog dizajna s predtestom i posttestom u ekvivalentnim skupinama. Svi instrumenti (predtest, posttest i retest) sadržavali su pitanja iz tri različite kognitivne domene: znanja, razumijevanja i razmišljanja. Analiza rezultata posttesta i retesta pokazala je da su učenici iz eksperimentalne skupine postigli znatno veću kvalitetu i kvantitetu znanja u sve tri kognitivne domene nego što je to bio slučaj kod učenika iz kontrolne skupine. Može se zaključiti da edukativni računalni programi imaju pozitivan učinak na poboljšanje učeničkih postignuća u nastavi biologije.

AbstractIn pedagogical research the results of which are presented in this paper, the teaching topic was Fundamentals of molecular biology of the biology curriculum for the fourth year of grammar ...school of the natural sciences and mathematics department. The experiment was carried out during 13 lessons of interactive computer-assisted teaching in the experimental group and by traditional teaching in the control group. The survey was conducted on a sample of 142 students in two grammar schools in the Republic of Serbia. The aim of this study was to determine whether the application of computer-assisted interactive teaching has achieved better results in helping learners acquire complex content in biology and reach higher levels of quality and quantity of knowledge in comparison with traditional teaching. The analysis of the study results confirmed higher efficiency of interactive computer-assisted biology teaching compared to the traditional approach to learning the same content. Differences which are statistically significant were found in student achievement between the experimental and control group in the final test and in the retest as a whole, and at individual levels of knowledge. They were: knowledge of the facts, understanding of concepts and analysis and reasoning. The research results recommend greater application of interactive computer-assisted biology teaching in grammar schools and in other high schools, especially when learning difficult educational content.Key words: competences in biology; fourth grade students; molecular biology; natural sciences and mathematics department; traditional teaching.---SažetakU pedagoškom istraživanju čiji su rezultati prikazani u ovome radu, naziv nastavne teme bio je Osnove molekularne Biologije, u skladu s Nastavnim planom i programom za Biologiju za četvrti razred prirodoslovno-matematičke gimnazije.

AbstractThe paper analyzes comparative effectiveness of the use of educational software and traditional teaching methods in biology instruction for high school students. A random sample consisted of ...173 students of grade 12 of a high school in Zrenjanin, Serbia, who were randomly distributed into the control and experimental groups. The students in the experimental group learned biology content (Mechanisms of Heredity) using educational software, whereas the students in the control group learned the same content using the traditional teaching methods. The research was carried out using the pretest - posttest equivalent groups design. All instruments (the pretest, the posttest and the retest) contained the questions belonging to three different cognitive domains: knowing, understanding and reasoning. The analysis of the posttest and the retest results showed that students from the experimental group achieved significantly higher quantity and quality of knowledge in all three cognitive domains than the students from the control group. It can be concluded that educational software has a positive impact on improving students’ achievement in biology teaching.Key words: achievement; genetics; teaching efficiency; traditional teaching.---SažetakU radu se prikazuje komparativna analiza učinkovitosti upotrebe edukativnog računalnog programa i tradicionalnih nastavnih metoda u nastavi biologije u srednjoj školi.
