Öğe The effect of blended learning model on high school students' biology achievement and on their attitudes towards the internet(2012) Ümit Yapici I.; Akbayin H.The present study aims to determine the effect of the blended learning model on high school students' biology achievement and on their attitudes towards the Internet. Among the experimental models, the pretest-posttest control group model was used in the study. The study was carried out with 107 students (47 of whom were in the experimental group, and 60 of whom were in the control group) attending Nevzat Ayaz Anatolian High School in Diyarbaki{dotless}r in Spring Term of the academic year of 2009-2010. In the experimental group, the courses were taught based on the blended learning model via a website (www.e-biyoloji.net), while in the control group, the courses were taught based on traditional teaching methods. An Internet Attitude Scale (?=0,97) and an achievement test of 40 questions (KR-20=0.88) were used as the data collection tools. For the analysis of the data, mean scores, independent t-test and paired samples t-test were used. The research results revealed that the blended learning model contributed more to the students' biology achievement than traditional teaching methods did and that the students' attitudes towards the Internet developed statistically significantly. © The Turkish Online Journal of Educational Technology.Öğe The effect of blended learning model on high school students' biology and internet self efficacy perceptions(2013) Yapici I.U.; Akbayin H.[No abstract available]Öğe An experimental study on mycelial development period of some Pleurotus species, P. ostreatus, P. sapidus and P. sajor-caju, on the media that contain certain amount of barley crumb or wheat flour(1998) Akbayin H.; Yildiz A.; Ertekin A.S.Cultivation of Pleurotus species as mushroom is becoming important throughout the world because of their abilities to grow in a wide range of temperatures, on various types of medium and their shorter cultivation time. The purpose of this study is to determine whether the media that contain 1% malt extract and 1%, 1.5% or 2% wheat flour or barley crumb significantly decrease the mycelium development period of Pleurotus species, P. ostreatus, P. sapidus and P. sajor-caju, compared with the media that merely contains 1% malt extract and to establish which media is more appropriate to produce mycelia of these species vegetatively. As a result, of this study, the media that contain 1% barley crumb and 1% malt extract for P. ostreatus, 1.5% barley crumb and 1% malt extract for P. sapidus, and 1.5% barley crumb and 1% malt extract for P. sajor-caju has been suggested.Öğe High school students' views on blended learning(2012) Yapici I.U.; Akbayin H.In this study, it is aimed to determine the high school students' views on blended learning. The study was carried out in biology course for the lesson unit of "Classification of Living Things and Biodiversity" with 47 9th grade students attending Nevzat Ayaz Anatolian High School in the second term of the academic year of 2009-2010. The lessons were taught in a way appropriate to the blended learning model both via the Internet and on face-to-face basis. As the online dimension of the blended learning model, Moodle, a Learning Management System (LMS), was used. The application lasted 10 weeks. The scale of learners' views on blended learning was applied and interviews were held to determine the views. As a result of the analysis of the scale, it was seen that their views were "highly" positive. The interviews held with the students revealed that the blended learning model provided students with various opportunities such as getting prepared for the lessons, reviewing the lessons as many times as wanted, reaching the subject-related materials without being dependent on time and place, testing oneself and communicating with the teacher and other students out of the school. The interviews also revealed that there were various problems though such as lack of Internet connection at home and problems experienced while playing the videos.Öğe Some biological characteristics of the Acanthobrama marmid Heckel, 1843 in the Tigris River (Turkey)(1994) Unlu E.; Balci K.; Akbayin H.Describes the following biological characteristics of Acanthobrama marmid: sex distribution, growth in length and weight, growth rates, condition factor, attainment of first maturity age, spawning period, and fecundity. -from Authors
