The class environment's having limited sources to bring in the new knowledge which is acquired with the fast developments in science and technology to the society in an easy understandable, and enjoyable way has caused the need for alternative environments (Bozdogan, 2007; Kisiel, 2007). These places which are described as informal education environments include mass media, sports centres, zoos, botanic parks, woodlands, museums, libraries, aquariums, open air laboratories, nature centres, and a of social areas which we wont be able to count here (Hannu, 1993; Howe & Disinger, 1988). Informal education environments' being fun and natural, the people visiting these places being volunteers and the introduction of opportunity of gaining different experiences and teaching to different age groups of people with different activities can be seen as an advantage (Taylor & Caldarelli, 2004). It was introduced by the researches conducted that different activities which were presented apart from formal education resources were rich teaching resources which made learning more fruitful (Ramey-Gassert, 1997), encouraged learning by different ways which the class environment wasn't able to introduce, helped each student to enlighten themselves in their own paces (Melber & Abraham, 1999) and support the education at school (Gerber, Cavallo, & Marek, 2001; Hannu, 1993).
One of the formal education environments which include a lot of fields is the field trips which are organized by the schools. These trips are one of the leading and effective education strategies which attract the attention of students and whose outcomes are permanent. This strategy is one of the ways which provide students unique opportunities to understand the natural environment and promote the sustainability of education. These natural environments help the concepts and complex knowledge which are told in school environment to be observed in its natural environment , to be aware of the real world and it also provides to gain experience at first hand (Bowker & Tearle, 2007; Kola-Olusanya, 2005; Leback, 2007; Rennie & McClafferty 1995; Scarce 1997; Skop, 2008; Tal, 2004b). They can also provide permanent change in the students' knowledge, attitudes and behaviours (Ballantyne & Packer, 2009; Knapp & Barrie, 2001; Orion, Hofstein, Tamir, & Giddings, 1997; Rudman, 1994; Tal & Morag, 2009). However, this condition must not mean that we deny the importance of education which is performed in the class because the best education takes place when a relation between intramural and extramural environments is built and carried out (Ballantyne & Packer, 2006; Kisiel, 2007). Moreover, it is emphasized that the field trips which are well-organised and associated with the school curriculum create successful outcomes (Bowker & Tearle; Kisiel, 2005; Tal, Bamberger, & Morag, 2005).
The field trips organised for the extramural environments which have such important functions are more difficult, complex and costly than formal education (Orion et al., 1997; Osborne & Dillon, 2007) and the teachers have important responsibilities during this process because the field trips which teachers organise by taking into consideration the needs and the interests of students provide the children not only to gain more experience and to get to know the world better but also develop the students' individual levels (Bowker & Tearle, 2007; Kisiel, 2005; Taylor, Morris, & Cordeau-Young, 1997). Furthermore, using scientific strategies during the planning process provide opportunities for the students to get to know their environment better, gain experience at first hand by doing observations and develop their problem-solving skills (Lisowski & Disinger, 1991; Taylor et al., 1997). But, the studies conducted reveal that teachers come across various difficulties in terms of management, counselling (guidance), and pedagogy while carrying out trips (Griffin & Symington, 1997; Kisiel, 2003; Michie, 1998; Olson, Cox-Petersen, & McComas, 2001; Tal & Morag, 2009; Tal & Steiner, 2006). It was observed that teachers were not aware of the aims of the trips they were taking (Cox-Petersen, Marsh, Kisiel, & Melber, 2003; Griffin, 1994, 2004; Griffin & Symington, 1997; Kisiel, 2003; Price & Hein, 1991) and they had difficulty in building a relation-\ ship between the trips and course syllabus (Griffin & Symington, 1997; Kisiel, 2007; Ramey-Gassert, Walberg III, & Walberg, 1994). It was found in the studies conducted that teachers do not take active roles during the field trips process although they know that if it is well-organised, the field trips will have effective outcomes on students, they do not have any ideas about the planning which is to be done for the field trips (Anderson, Bethan, & Mayer-Smith, 2006; Ferry 1993; Tal 2004a; Tal et al., 2005) and they are incompetent about guiding students (Cox-Petersen & Pfaffinger, 1998; Griffin & Symington, 1997; Kisiel, 2005; Wellington, 1990). In addition, it was determined that teachers perceived the field trips as only interesting and enjoyable places (Cox-Petersen & Pfaffinger, 1998; Griffin, 1994, 2004; Griffin & Symington, 1997; Kisiel, 2003; Michie, 1998; Olson et al., 2001; Tal et al., 2005). Although the studies conducted reveal that the field trips had a very big potential to complete the education at school, it was seen in the studies above that a lot of teachers were not aware of their roles during this process and they did not use these resources effectively. This may have a lot of reasons. One of them is that while doing different activities outside the school teachers and teacher candidates are under time constraints and this pressure leads to reluctance about organising trips (Brewer, 2002; Howitt, 2007; Lindemann-Matthiesa et al., 2009). At the same time, taking the responsibility of the students and keeping them under control are the conditions which make teachers worry the most (Kisiel, 2007). Teachers' personal experiences (organized with their classes or joined while they were teacher candidates) and the conditions of both the school and the class (support for the trips by the school, number of students in the class, student interest, time, etc) play an important role during the preparation of trip (Bozdogan, 2007; Disinger, 1984; Kisiel, 2005, 2007).
The studies conducted introduce the importance of encouragement and enlightenment of teachers about the subjects such as doing preparations and informing students before the trip, associating the trip with the school curriculum, giving a good and comprehensive guidance to their students during the trip and leading them and doing different in-class activities after the trip (Anderson, Lucas, & Ginns, 2003; DeWitt & Osborne, 2007; Orion & Hofstein, 1994; Tal, Bamberger, & Morag, 2005). Within this context, it was determined that teacher candidates should be given professional training and the institutions which educate teachers have important duties during this process (Anderson, Lucas, & Ginns, 2003; Kisiel, 2007; Tal, 2004a). Doing activities to develop teachers (Barker, Slingsby & Tilling, 2002) and providing opportunities for the teacher candidates to restructure their knowledge by taking field trips, to gain experience and to develop themselves (Tal, 2001) were required to be emphasized especially in the primary education teaching programmes because the field trips carried out with teacher candidates develop their skills to use different extramural resources and different teaching methods, their scientific process skills and pedagogic knowledge. Moreover, it helps them to understand how to do a scientific field trip. In addition to this, it helps them to build an easier relationship between the education studies carried out in extramural environments and the education given in the school (Melber & Cox-Petersen, 2005). Thus, a study which was conducted to gain experience to teachers and teacher candidates about how to do education in extramural environments introduced that teachers and teacher candidates gained a lot more knowledge and experience with 2 or 3 sample field trips which were carried out with careful planning and preparations as well as with teacher support and collaboration. The study conducted also revealed that teacher candidates had carried this experience which they gained to a level where they can organize a field trip with different classes and levels of students (Tal & Morag, 2009).
The studies conducted showed that teachers had come across a lot of problems during the preparation of educational oriented trips to extramural environments and they also revealed that teacher candidates should be given professional education to solve these problems. The study which was conducted within this context aimed at showing how teacher candidates can organize an education oriented trip in extramural environments and revealing their practises and views during the process. So, one of the problems which appear in Literature was about how to carry out the planning of trips; therefore, this problem was tried to be emphasized by doing practices.
Action research, one of the qualitative research methods, was used in the study. Action research is suitable for the individuals who are directly related to the process to be developed and it can also be used to solve the professional problems a person meet in his field of expertise or to increase the quality of the work he does (Büyüköztürk, Çakmak, Ak gün, Karadeniz, & Demirel, 2010). It was thought in the study conducted that the use of this method was suitable to show prospestive teachers how to organize an education oriented trip in extramural environments and provide the reinforcement of the process with the practices.
The factors enriching validity in qualitative researches are to collect detailed and in-depth information via face to face interviews and collecting information directly and in the natural environment where the event takes place through observations (Yildirim & Simsek, 2000, 2006). To increase the validity of the study conducted within this context, observations were done in the natural environment where the trips were organized by the researcher and these observations were recorded by photographs. The position of the researcher in the trips, his source of data, social environment and processes, explanations about data collection and analysis methods are the factors that enrich reliability (Yildirim & Simsek, 2000, 2006). To increase the reliability of the study conducted within this context, detailed explanations for the further levels related to the position of the researcher in the trips, social environment and processes, explanations about data collection and analysis methods are done.
Because the study group is formed by the people who are directly related to the problem in action research (Büyüköztürk et al., 2010), 17 prospective science teachers who stated that they had chosen the elective course called "Science Teaching in Informal Learning Environments" as they did not have the knowledge of organising education oriented trips to extramural environments according to suitable sampling method participated in the study. Within the scope of the study, trips were organised to Gaga Lake in Ordu, Gümüshane Karaca Cave, and Giresun Kulakkaya plateau in the first year and to Fiskobirlik EFIT AS. Factory in Giresun, Fresa Mineral Water Factory, and Dogankent Hydroelec-tricity plant in the second year.
Data Collection Tools
Observation form and semi-structured interview form prepared by the researcher were used to collect data. Two field experts analysed the observation form and interview form and necessary corrections were made with feedback, so the content reliability of the evaluation tools were tried to be confirmed.
The data related to the physical condition of the environment, activities done and the social and the individual interaction between prospective science teachers were obtained by the observation form prepared by the researcher. The researcher filled one observation form each trip during the process and tried to record the observations with photographs. In addition to this, the data obtained by semi-structured interview forms were subjected to content analysis. The data obtained through interviews were firstly written down and then the interview questions were accepted as the themes. According to the themes put forward by the research questions, the expressions were divided into categories; coded, summarised and interpreted by 3 different experts. For the reliability of the research, the coding consistency of the emerging categories was calculated. It was calculated by using the formula stated by Türmüklü (2000) as compatibility (matching) percentage in his study which is P = Na / Na+Nd x100 (P: matching percentage; Na: compatibility quantity; Nd: incompatibility quantity). The average compatibility percentage of the questions in the interview was calculated as 0,91 .
The distribution of implementation stages of the research according to the weeks was summarized below.
a) First, Second and Third Weeks (9 Lesson Hours-Class Environment): The questions prepared with semi-structured interviews technique were asked to the prospective science teachers before the lesson and these answers were recorded. The interviews conducted for each prospective teacher lasted 10 minutes on average. Then, prospective science teachers were informed by the researcher in the class environment about how to organize an education oriented trip and what they should pay attention during this process. Within this context, firstly, the importance of education oriented trips in terms of science teaching was told by making use of the literature and then the knowledge was made to be objectified with the examples given from the previous trip plans. Then, it was explained how to organize the trips which are going to be taken to the prospective science teachers stage by stage. PowerPoint presentations and visual materials (photographs, video plays, etc) were made use of in the lessons. Prospective science teachers were divided into three groups every two years because trips would be organized to only three different extramural environments during the "science teaching elective course process in informal learning environment". In order to address more effectively to the cognitive and affective field skills of science teacher candidates, the choice of places for the trips were decided by these groups. Thus, science teacher candidates were provided opportunities to conduct their studies enthusiastically. It was especially stated that the place of trip should be related to science subjects because the trips taken were education oriented and prospective science teachers were made to associate the place of trips with science subjects while making their choices.
b) Fourth and Fifth Week (6 Lesson Hours-Class Environment): Prospective science teachers had associated the place of trips with science subjects and then begun preparations to be made before and during the trips. During this process, the preparation of brochures for the advertisement of trip, the preparations made for guidance and the preparations of evaluation questions were completed.
c) Sixth, Seventh, Eighth, Ninth, Tenth and Eleventh Week (18 Lesson Hours-Field Trip): After all preparations were completed, practices started. In this process, a trip was taken in the first week and an evaluation was carried out in the class in the second week. Then, while going to the trip field, the group who was the guide that week distributed the advertising brochures to prospective teachers and asked them to read the brochures and answer the questions before the trip. This is a kind of activity which enables all prospective teachers to have information about the place of trip before the trip. When they reached the place of trip, the group members who were going to be the guide for that trip divided the other prospective teachers into groups of two or three and gave information about the place of trip within the framework of information leaflets which they had prepared before. Prospective teachers were made to answer the questions which they were required to answer during the trip at the end of the process. And then all the brochures and the papers where there were the answers of questions asked to prospective teachers were collected by the guide group to be evaluated a week later.
d) Twelfth Week (3 Lesson Hours-Class Environment): After the trips were completed, all of the prospective teachers were asked open-ended questions which were prepared by the researcher using semi-structured interview technique.
When the observations done were evaluated in general, it was observed that because the groups who did the guiding in Gaga Lake where the first trip was organised in the first year and in Fiskobirlik EFlT A?. Factory where the first trip of the second year was organised were the first groups, they were excited and uneasy at the beginning. It was also observed that prospective science teachers who joined the trip were usually cheerful. It was found as a result of the observations that prospective teachers who joined the trip usually listened carefully to both the group who were the guides and the guides who were assigned by the institutions (Fiskobirlik EFlT A?., Dogankent HES, Karaca Cave and Fresa Mineral water Factory) where the trip took place. Prospective Science teachers' asking questions constantly to the guides to get information about the place of trips is a fact which shows that the trips were taken seriously. Moreover, it was seen in the observations done in the trips that prospective science teachers helped each other while answering the questions to be answered during the trip. So, it can be said that field trips developed social interaction and helped learning. In an interview which was carried out with the prospective science teachers who hadn't taken the lesson before, it was determined by 21 prospective teachers that they would organise it with the aim of entertainment, 7 of them would organise it for the purpose of education and 6 prospective teachers would organise it both with the aim of entertainment and education. In an interview which was conducted at the end of the term, it was observed that the views of prospective teachers had differed a great deal. 24 prospective teachers determined that they would organise the trip both with the aim of education and entertainment, 8 of them said that they would organise the trip for the purpose of education and 2 of them stated that their trip would be for the sake of entertainment. The interview which was conducted with the prospective science teachers before the lesson revealed that 14 of them were not confident about organising trip, 14 of them partially believed in themselves and only 6 of them were confident about it. However, it was observed at the end of the term that nearly all of the prospective teachers believed in themselves about organising trips.
In the interviews which were conducted at the end of the term prospective science teachers were asked the question of what kind of benefits the practices had for them and all prospective science teachers stated that the practices done were useful on the level knowledge, 28 of them benefited from them in terms of skills and experience and 18 of them said that their confidence increased with them. It was seen before the lesson that what organising trips mean for prospective science teachers is that they often put emphasis on such conditions as arranging transportation vehicles for the activities to be done before the trip, getting the necessary permissions for the trip, collecting the fares, and meeting the needs for food and beverage during the trip. The number of prospective teachers whose focus is on the educational function before the trip is 14. The number of prospective teachers who put emphasis on the activities to be done during the trip and the activities (evaluation) to be done after the trip is only 6. When the views of the prospective science teachers were analysed, the conclusion reached was that the factor which led them to think like that was their previous life. It was observed at the end of the term that prospective science teachers were able to give quite detailed and illuminating information. It was found that all prospective science teachers mentioned educational preparatory function and bureaucratic procedures - transportation issues, two of the activities which were to be done before the trip and evaluation activities after the trip. It was determined that 32 of them mentioned the activities to be done during the trip and 24 of them mentioned food and beverages, which is one of the activities to be done before the trip and accommodation. These results reveal that at what level the studies conducted are effective. Nearly all prospective teachers answered this question that information would be objectified and its permanence would increase. Again 16 prospective teachers stated that students would improve various skills such as observation, questioning, interpretation and 14 of them determined that interest and attitude to science lesson would be promoted. In addition to this, 8 prospective teachers determined that it had effects on students' social development and 8 of them said that it had effects such as promoting enjoyable learning environment. In an interview conducted at the end of the term, the answers of prospective science teachers to the question "Do you have any anxieties while organising education oriented trip and during the trip? Why?" were analysed and it was found that 20 of prospective science teachers were not anxious where as 14 of them had some anxieties. When such anxieties were analysed, it was found that the condition which created the most anxiety were safety concerns and the trip's being not able to reach its goals. These were followed by not being able to provide the student control, time concerns, bureaucratic issues and cost concerns
Although the education studies conducted in informal education environment are more difficult, complex and costly than formal education (Orion et al., 1997; Osborne & Dillon, 2007), these places appear to be an attractive education environment because they have very important functions for the students to acquire cognitive, affective, and psychomotor skills (Orion &Hofstein, 1994; Tal & Morag, 2009). However, a lot of studies conducted reveal that a lot of teachers are not well-informed and equipped enough to plan and implement the trips and because they cant fulfil their roles in this process, they can not benefit from these resources effectively (Griffin, 1994; Griffin & Symington, 1997; Kisiel, 2005, 2007; Orion & Hofstein, 1994; Storksdieck, 2001; Tal & Morag; Wellington, 1990). It was expressed that within the context the teachers should be informed and encouraged with the help of an instructor on issues such as making preparation before the trip, associating the trip with the school curriculum, giving good and detailed guidance to their students during the trip, and instructing them and doing different in-class activities after the trip (DeWitt & Osborne, 2007; Tal, 2004a) and it was also emphasised that the institutions which educate teachers have important concerns (Anderson et al., 2003). With the study conducted, the planning process of an education oriented trip was explained to the prospective science teachers theoretically and by making them do implementations in 6 different extramural environments, they were helped to gain experience. The observation carried out during the implementations proved that prospective science teachers were usually enthusiastic and cheerful during the trips. So, it can be said in this condition that education oriented trips have the potential to provide learning with entertainment. It was also seen with the observations that prospective science teachers listened to not only the groups who guided them but also the guides who were assigned by the institutions where the trip took place carefully (Fis-kobirlik EFlT A$., Dogankent FES, Karaca Cave and Fresa Mineral Water Factory) and they made an effort to have information. This condition makes us think that prospective science teachers were enthusiastic to have information about the place of trip and took the trip seriously. In addition to this, it was observed that prospective science teachers were in collaboration with each other during the trip and from here it was concluded that education oriented trips developed social interaction and helped learning.
It was revealed in the interviews which were conducted before the lesson that two-thirds of prospective science teachers stated that the schools trips which they joined in during their previous teaching levels had usually the purpose of fun that and because of this, they would maintain this in their professional life. Hence, it is revealed that how previous experiences affect prospective science teachers about organizing trips. It was found in other studies that the personal experiences of teachers played an important role during the organisation of trips and the trips (Kisiel, 2005, 2007). It was observed in the interviews which were conducted after the practises that the views of the prospective science teachers had changed considerably. It was determined that nearly all prospective science teachers stated that they had understood how serious issue the process of planning and organising trip was and after they started their jobs, they would prefer trips which include largely education and also the element of fun. From here prospective teachers were thought to realize that extramural environments were amusing environments but also very important places for education. Within this context, supporting science teachers about planning and implementation of an trip with applied practises at universities would contribute them to gain positive experiences because the studies conducted reveal that there are very rare implementations about this subject in institutions that educate teachers (Anderson et al., 2006; Ferry 1993; Tal 2004a) and if 2 or 3 sample trips are carried out for teachers/ prospective teachers about how to give education in extramural environments, they will be able to get more information and experience (Tal & Morag, 2009).
It was determined in the interviews carried out before the implementations that more than two-thirds of prospective science teachers did not believe in themselves about planning an trip but all prospective teachers except one believed in themselves after the implementations. Having an opportunity to do practice in the trips organised appear to be an element which increases the self confidence of prospective science teachers. It was proved in a study conducted that the experiences obtained as a result of implementations developed self confidence of prospective teachers and also increased their interaction and communication with the students (Wang, 2004). It was observed before the lesson that what planning trips meant for prospective science teachers was to put emphasis on such conditions as arranging transportation vehicles for the activities to be done before the trip, getting the necessary permissions for the trip, collecting the fares, and meeting the needs for food and beverage during the trip. The factor which underlies such planning of them introduces the fact that it was related to their previous trip experiences as they stated in the interviews. However, the interviews conducted after the implementations revealed that nearly all of the prospective teachers gave quite detailed and explanatory information about planning a trip. Moreover, prospective science teachers stated that the field trips taken contributed to them considerably on cognitive, affective, and psychomotor levels. This showed that at what level the implementation studies were effective Tal (2001; 2004b) stated that prospective teachers restructured their knowledge, gained experience, and developed themselves by taking field trips. As it is seen, the results reached as a result of implementation studies look as if they support the studies conducted before.
Prospective science teachers stated in the interviews carried out that field trips would be able to provide very important contributions to students. Nearly all prospective teachers stated that because students acquired information at first-hand, the teacher should be permanent. Again, nearly half of the prospective teachers stated that the students would be able to improve such skills as observation, questioning, interpretation in field trips and this would increase the interest in science courses. One quarter of prospective teachers stated that field trips would develop students' social and communication skills. The views of prospective teachers show parallelism with the results that occur in the studies conducted before (Bowker & Tearle, 2007; Farmer, Knapp, & Benton, 2007; Lisowski & Disinger, 1991; Taylor et al., 1997).
The interviews carried out after the implementations reveal that nearly two-thirds of prospective teachers would not have any anxiety during the process of planning an trip where as one-third of them would carry various anxieties. It was observed that the biggest anxiety of prospective teachers was the safety concerns and the trip's not reaching its aim. Especially female prospective teachers were observed to be more anxious about safety concerns than male prospective teachers. It was observed in the interviews conducted that female prospective teachers were so anxious that something would happen to the students if an accident occurred during the trip. Moreover, the anxiety of female students being not able to control the crowded classes was higher than the men. The other anxieties of prospective teachers could be listed as time, cost and bureaucratic issues. Similar results were reached with the studies conducted before. For example, Kisiel (2005, 2007) listed the situations which teachers were anxious about organising trips in his studies conducted as the teacher's pedagogical perceptions of organising trips, the previous experiences of teachers and students, their school conditions and taking the responsibility of students and putting students under control. It was found in another study conducted that teacher candidates were under time-constraints (Lindemann-Matthie-sa et al., 2009). Bozdogan (2007) reached similar results, too.
The result of the study conducted revealed importance of teacher educating institutions about how to plan and implement teaching in extramural environments. These institutions can check out their programs and provide expert support to prospective teachers about this subject. However, it can be said that extramural environments can be successfully integrated into the formal education in that way. The institutions educating teachers can implement trip based educational courses either compulsory or elective in extramural environments to their teaching programmes, they can encourage such studies and support them with providing necessary equipment, tools and materials. Moreover, it is important to conduct studies with different prospective teachers and teacher groups to introduce the effects of using extramural environments explicitly in education so data can be obtained in a large perspective.
