It is highly emphasized that laboratory experience is an effective way to teach science notions deeply and substantially. The aim of this work is to reveal the laboratory experiences which the science teachers receive in preservıce perıod durıng hıgh school educatıon. 120 First Grade students who study at The Faculty of Education, Primary School Education, Science Teaching Department in Muğla Sıtkı Koçman University attended in this work in 2012‐2013 Academic Year. The data of the work was collected from the essays which were written by these students. The students answered some open ended questions in their essays. In order to understand these essays a semi constructed interview was conducted among 10 students that were chosen randomly. Descriptive analysis and content analysis were used while analysing the qualitative data that was gained. It is founded that laboratory experiences of children are very limited due to the reasons such as the lack of labs in schools, the inadequacy of the labs in schools or the inadequacy of the lab teachers. These can be offered according to the findings of this work:
some seminars can be given to the high school teachers who give the science, chemistry and biology lessons in order to make them use the labs more efficeintly.

INVESTIGATING PRE‐SERVICE MATHEMATICS TEACHERS’ VIEWS ABOUT VECTOR APPROACH TO GEOMETRY AND INSTRUCTIONAL METHODS DURING GEOMETRY TEACHING
VİLDAN KATMER‐BAYRAKLI, HATİCE AKKOÇ
Recently, there have been curriculum changes in geometry in Turkey as well as in other countries. The most obvious change in geometry curriculum in Turkey is the introduction of “vector approach”. This study investigates pre‐service mathematics teachers’ views about vector approach and instructional methods used by them during geometry teaching. Participants of the study are thirty‐seven pre‐service mathematics teachers who were at the last year of a teacher preparation program in secondary mathematics teaching during 2011‐2012 academic years. At the first phase of the study, questionnaires with open‐ended questions were administered to thirty‐seven pre‐service teachers to reveal their views about vector approach to geometry. Data obtained from questionnaires was analysed using content analysis. At the second phase of the study, four participants were selected using purposive sampling.
Instructional methods used by these participants were investigated by analysing their lesson plans, micro‐teaching lessons and semi‐structured interviews. Data obtained from these sources was analysed using descriptive analysis.
Findings from the data indicated that thirty‐seven pre‐service teachers had both positive and negative views about vector approach. In addition, all four participants used teacher‐centred instructional methods during their lessons although they were in favour of vector approach since it prevented rote‐learning and it could help students discover concepts for themselves.

ELİF BÜLBÜL, ÇİĞDEM ŞAHİN, ÜMMÜ GÜLSÜM DURUKAN
Araştırmanın amacı, ortaokul 7. sınıf öğrencilerinin uzay araştırmaları konusunda sahip oldukları alternatif kavramları kavram karikatürleri ile belirlemektir. Araştırmanın örneklemini 2012‐2013 eğitim öğretim yılında güz dönemi, Van’ın bir ilçesinde yatılı bölge ortaokulunda 7.sınıfta öğrenim gören 53 ortaokul öğrencisi oluşturmaktadır. Özel durum metodunun kullanıldığı bu çalışmada, veri toplama aracı olarak “Uzay Araştırmaları” konusu ile ilgili 11 kavram karikatürü hazırlanmış ve kullanılmıştır. Kavram karikatürleri hazırlanırken ortaokul 7. sınıf fen bilimleri dersi öğretim programındaki kazanımlarından ve literatürde belirlenen alternatif kavramlardan yararlanılmıştır. Kavram karikatürlerinin geçerliliği için 5 alan eğitimi uzmanının görüşleri alınmış ve kavram karikatürlerinin pilot uygulaması yapılmıştır. Elde edilen veriler betimsel olarak analiz edilmiştir. Öğrenci cevapları kategorileştirilmiş ve cevapların ifade edilme sıklıkları hesaplanmıştır. Araştırmada, ortaokul 7. sınıf öğrencilerinin “Uzay Araştırmaları” konusunda birçok alternatif kavramlara sahip oldukları tespit edilmiştir.
Anahtar Kelimeler: Alternatif kavram, kavram karikatürleri, ortaokul 7. sınıf öğrencileri, uzay araştırmaları.

INVESTIGATION OF SECONDARY SCHOOL 7th GRADE STUDENTS’ ALTERNATIVE CONCEPTS ABOUT SPACE RESEARCHES
ELİF BÜLBÜL, ÇİĞDEM ŞAHİN, ÜMMÜ GÜLSÜM DURUKAN
The purpose of this study was to determine the alternative concepts of the secondary school 7th grade students about space researches by concept cartoons. The sample of this study composed of 53 secondary school 7th grade students who study in a town of Van set in 2012‐2013 academic years‐ fall term. At this study which was used case study method, 11 concept cartoons that are related to space researches were prepared and used as data collection tool. While concept cartoons are prepared, were used from acquisitions of secondary school 7th grade science lesson and alternative concepts were examined in the literature. For the validity of concept cartoons, 5 field education experts’ views were taken and the pilot implementation of concept cartoons was done. The data obtained were analyzed descriptively. Students’ answers were categorized and the sequence of finding voice in answers was calculated. It is determined that secondary school 7th grade students have many alternative concepts about “space researches” in this study.
