This study was performed to determine what content in biology was perceived as difficult and important to learn and to investigate whether there is a relationship between reasoning ability, gender, perceived difficulty and importance. A total of 397 Grade 11 students and sixteen biology teachers participated in the study. Students and teachers̕ perceptions of difficult and important to learn concepts were determined through a questionnaire. Moreover, semi-structured interviews were conducted with students and teachers to determine the intrinsic difficulties and sources of difficulties. Descriptive statistics was used to determine frequencies of difficult, moderate and easy biology concepts as perceived by students and teachers. Biotechnology and genetic engineering, hormones, photosynthesis, genes, Mendelian genetics and respiration were found to be difficult concepts for students to learn. On the other hand, the students identified producers, consumers, and decomposers, active transport, diffusion and osmosis as easy topics. In addition, cell, enzyme, cell division, respiratory system in vertebrates, protein synthesis, and reproduction in animals are selected as important topics in the curriculum to be learned. On the contrary, body systems in invertebrates and animal tissues are found to be less important topics to be learned. Students̕ reasoning ability was assessed by using Group test of Logical Thinking (GALT). While a statistically significant negative correlation was found between reasoning ability and percieved difficulty (r= -.115, p<. 05), no statisticaly significant relationship between gender and perceived difficulty was found.

An İnvestigation of the teaching-learning process based on multiple intelligence theory in a high school biology course
Presley, Arzu İrfan; Aşkar, Petek; Department of Secondary Science and Mathematics Education (2005)
This study sought to investigate the effects of multiple intelligences based instruction (MIBI) and learning styles on ninth graders̕ attitudes toward biology, biology achievement, and overall multiple intelligences. This experimental research was conducted in the second term of 2002-2003 educational year in Ereğli high school. The sample involved in the study consisted of 64 students from the two different ninth grade classes taught by the same teacher. One class was assigned as the experimental group in w...
The effect of inquiry based chemistry course on students' understanding of atom concept, learning approaches, motivation, self efficacy, and epistemological beliefs
Çalışkan, İlmiye Sevilay; Geban, Ömer; Department of Secondary Science and Mathematics Education (2004)
The purpose of this study was to explore the effects of inquiry-based high school chemistry course and gender differences with respect to students̕ understanding of atom concept, learning approaches, motivational goals, self-efficacy, and epistemological beliefs. In this study, 47 ninth grade students from classes of a chemistry course were taught by the same teacher in Private Yüce Science High School in the 2003-2004-spring semester were enrolled. There were two groups in the study. Two instruction method...
Explaining the relationship between high school students' selected affective characterstics and their physics achievement
Doğan Tekiroğlu, Özlem; Eryılmaz, Ali; Department of Secondary Science and Mathematics Education (2005)
The purpose of this study is to investigate the relationship between some of selected affective characteristics of high school students related to physics lesson and their physics achievement in electricity concept. These affective characteristics of the students includes their interest in physics, importance of physics, enjoyment of extra-curricular activities related to physics, physics course anxiety, physics test anxiety, achievement motivation in physics, student motivation in physics, self-efficacy in...
The effect of problem based learning instruction on 7th grade students’ science achievement, attitude toward science and scientific process skills
Serin, Gökhan; Eryılmaz, Ali; Department of Secondary Science and Mathematics Education (2009)
The purpose of this study is to investigate the effect of instruction based on problem-based learning (PBL) on 7th grade students’ science achievement, attitude toward science course and scientific process skills. The study was conducted in May 2007 with 141 students and four science teachers from four middle schools in Gölbası district of Ankara. A total of eight classes were participated in the study. Four of them were assigned randomly to control group and four of them were assigned randomly to experimen...
The effect of explicit embedded reflective instruction on nature of science understandings, scientific literacy levels and achievement on cell unit
Köksal, Mustafa Serdar; Geban, Ömer; Department of Secondary Science and Mathematics Education (2010)
The purpose of this study is to investigate the effectiveness of explicit-embedded-reflective (EER) instruction on nature of science (NOS) understandings, scientific literacy levels and cell content knowledge of the ninth grade advanced science students. This study has been conducted with 71 students by using non-equivalent quasi-experimental design. In the treatment groups, the EER teaching has been conducted while NOS instruction in the comparison group for the same time interval has been done by lecture,...
