The purpose of the study is to examine the effect of project based learning oriented instruction (PBLOI) on 11th grade students’ achievement in human circulatory system concepts and their attitudes toward biology as a school subject when compared to traditional designed biology instruction (TDBI). Seventy two 11th grade students from two classes in a public high school in Ankara participated in this study in the second semester of 2008-2009. These classes were randomly assigned as control and experimental groups. In the experimental group PBLOI was used while in the control group TDBI was used. Human Circulatory System Achievement Test and Attitude Scale toward Biology were given to the control and experimental groups as pre-tests and post-tests in order to assess students’ achievement in human circulatory system and their attitudes toward biology, respectively. In addition, Science Process Skills Test was administered to both groups at the beginning of the study in order to assess students’ science process skills. In order to test the hypotheses of the study, Analysis of Covariance (ANCOVA) and Two-Way Analysis of Variance (ANOVA) were used. The results show that PBLOI caused a significantly better acquisition of scientific concepts related to human circulatory system than TDBI. However, there was no significant effect of PBLOI on students’ attitudes toward biology. In addition, there was no significant effect of gender on both students’ achievement in human circulatory system and their attitudes toward biology.

The main purpose of this study was to compare the effectiveness of multiple intelligences based instruction (MIBI) over traditionally designed instruction on ninth grade students’ achievement in the unit of basic compounds of living organisms concepts and attitude toward biology as a school subject. In addition, the effect of gender difference on achievement in the unit and attitudes toward biology were investigated. Students’ science process skills were also investigated. 59 ninth grade students from two d...

The purpose of this study is to examine the effect of a project based learning (PBL) for 7th grade science unit titled “Cell and Divisions,” in terms of academic achievement, compared to traditional science instruction. Four groups of students in two schools in Bodrum, Muğla participated in the study in the 2018-2019 Fall semester. The intervention utilized pre and post-test control group quasi-experimental design with retention test where classes were randomly assigned to experimental (PBL) and control (tr...
Effect of physical modeling and computer animation implemented with social constructivist instruction on understanding of human reproductive system

Main purpose of the study was to compare effectiveness of the physical modeling and computer animation implemented with social constructivist and traditionally designed instruction on 10th grade students’ understanding of human reproductive system, motivation towards learning biology and types of achievement goal orientation. Design of the study was quasi-experimental with 125 students from six intact classes in a private high school in Ankara. Three groups for both experimental and controlled groups were r...
A group of students' and teachers' perceptions with respect to biology education at high school level
Özcan, Nesrin; Öztekin, Ceren; Department of Secondary Science and Mathematics Education (2003)
This study aimed to explore students̕ and teachers̕ perceptions with respect to biology education at high school level in order to reveal the reasons of students̕ low achievement in biology as indicated by the university entrance examinations between the years 1996-2002. The study was conducted with a qualitative approach. Therefore two separate interview schedules were developed to be conducted with 45 high school biology teachers and 45 eleventh grade science students in 10 schools including private, Anat...
The effect of gender and reasoning ability on the students’ understanding of ecological concepts and attitude towards science
Soylu, Hacer; Çakıroğlu, Jale; Department of Secondary Science and Mathematics Education (2006)
The purpose of this study was to investigate the effect of gender and reasoning ability on the 8th grade students’ understanding of ecological concepts and attitude toward science. All 8th grade students from public elementary school in Tosya participated in the study. Students’ understanding, attitude toward science and reasoning ability were also measured by means of the Test of Ecology Concept (TEC), the Attitude Scale toward Science (ASTS) and the Test of Logical Thinking (TOLT) respectively. In order t...
