Abstract
The rapid increase of scientific knowledge makes it diffucult to keep pace with. At this point, technology has become to guide us. Using technology for our needs and to access scientific knowledege has been adopted by all segments of society. Thus, it is easier to understand the rapidly developing and changing world. One of the areas where technology is effective is education. Technology reshapes both traditional relationships between teachers and students and the educational environment. The use of technology in education comes up with different examples in each part of the lessons. Traditional assessment and evaluation approaches are far from measuring high-level thinking skills. Alternative measurement and assessments are process-based methods which place students on center, help them express their ideas,and allow them to involve actively in all processes of learning. It is a known fact that alternative measurement and assessment techniques are insufficient in Turkey and the world. Technological pedagogical field knowledge research has emphasized the gap in this field in recent years. Portfolios are important tools in a process-oriented assessment. Electronic portfolios offer a lot of convenience for both the learner and the evaluator compared to traditional portfolios. In addition, the evaluator can reach full and realistic results about the learner .The study was carried out with 48 students with different socio-economic characteristics who participated in the project “I learn about nature by exploring from Microworld to Macroworld in the Ilgaz Mountain National Park- 3, which was realized within the scope of TÜBİTAK 4004 Nature Education and Science schools support program in 2016-2017 academic year. 30 students actively participated in the study and were able to create an electronic portfolio via the flip grid site during the training period. The students recorded 60-90 seconds of videos about the education and recorded them in the system. Project practitioners actively evaluated the training process and provided feedback using multimedia environments. In this way, whether the participants can achieve the related gains and the missing aspects of the training process were examined from a different perspective.
