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, demonstration and questioning strategies. Views on Nature of Science Questionnaire-Form C, Nature of Science Literacy Test, Cell Content Knowledge Test, and interviews have been used for data collection. Categorization of the participants’ profiles on the NOS aspects, paired samples t-tests and one-way Multivariate Analysis of Variance (MANOVA) have been used for data analysis. The results have shown the participants have had misunderstandings about “one method in science”, “no hierarchy between law and theory” and “difference between observation and inference” while they have had expert views on “role of creativity and imagination” at the beginning of the study. For elimination of naïve views, the EER approach has been found as effective. The approach has also been determined as effective on the increase in scientific literacy levels and learning on cell unit. In addition, the EER approach is more effective on learning cell content knowledge and gaining expert understandings of NOS than common approach in comparison group while there has been no difference between the scores of two groups in terms of scientific literacy levels.

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 effects of hands-on activity enriched instruction on sixth grade students' achievement and attitudes towards science
Türk, Özlem; Çakıroğlu, Özlem; Department of Secondary Science and Mathematics Education (2005)
This study aimed to investigate the effectiveness of hands-on activity enriched instruction on sixth grade students̕ achievement (on sense organs) and attitudes towards science. In this study, Science Achievement Test and Science Attitude Scale were used to assess students̕ achievement on sense organs and students̕ attitudes towards science, respectively. Also, hands-on activities about sense organs were prepared. This study was conducted with 2 teachers and 4 classes and total of 140 sixth grade students i...

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...
The effect of explicit embedded reflective instruction on nature of science understandings in advanced science students
Koksal, Mustafa Serdar; Çakıroğlu, Jale; Geban, Ömer (Informa UK Limited, 2013-12-01)
The purpose of this study is to investigate the effectiveness of explicit-embedded-reflective (EER) instruction in nature of science (NOS) understandings of ninth-grade advanced science students. This study was conducted with 71 students, who were divided into three groups, by using non-equivalent quasi-experimental design. In the treatment groups, the EER teaching was conducted, while in the comparison group NOS instruction was carried out in the same time interval by lecturing, demonstration and questioni...
The effect of instructional comics on sixth grade students' achievement in heat transfer
Özdemir, Ertuğrul; Eryılmaz, Ali; Department of Secondary Science and Mathematics Education (2010)
The purpose of this study is to investigate the effects of instructional comics on sixth grade students' achievement in heat and temperature. The population of the study was all of the sixth grade students in public elementary schools in Yüzüncü Yıl district. The sample of the study was 113 sixth graders from three public elementary schools in Yüzüncü Yıl district. In the beginning of the matter and heat chapter of science and technology course, the implementation started with the pretest. Then, a series of...
