Abstract
The aim of this study is to research the different methods used by biology teachers
and their effects on the success of the students. Three student groups of biology students in
University “GoceDelcev”, Faculty of Natural and Technical Sciences, Institute of Biology, -
Stip, R. Macedonia were offered a topic on general characteristics of Hemoglobin, Methods
Based on color development (Sahli’s/acid hematin Method) with different sequences of 3
teaching methods. The teaching methods were Laboratory method (student experiment), slide
demonstration and lecture method. The first group started the course with experiments in the
laboratory, then the lecture method was given to relevant theory of proteins, and then the
slides were shown (Group I). The sequence of these three teaching methods used in the first
group was changed in both second and third group as follows:
The lecture methods, slide show and experiment in Group II, and slide show, experiment and
lecture method in Group III, respectively. Laboratory method used in the study was focused
on the topic of Estimation of hemoglobin - Мethods based on color development (Sahli’s/acid
hematin Method)
This experiment was carried out by students. Slide demonstration method included slides
about hemoglobin structure and function. The slides were shown by teachers. Lecture method
was performed by teachers as usual. Effectiveness of different sequential teaching methods
was measured quantitatively by an achievement test. Achievement test contained 20
questions, testing the knowledge of facts as well as the ability to transfer the knowledge and
problem solving ability. This test was used as pre-test before methods’ application, post-test
after the methods’ application and retention test after 30 days from methods’ applied.
