This study aims to determine the effect on the achievement, motivation and selfsufficiency of students of the flipped classroom approach adapted to Keller's ARCS (Attention, Relevance, Confidence and Satisfaction) motivation model and applied to a physics course. The study involved 66 students divided into two classes of a physics course. The first class used the traditional lecture format while the flipped classroom model was used in the second. The research data were obtained via the physics concept test, motivation questionnaire, physics self-sufficiency scale and semi-structured interviews. It was found that the experimental group students were achieve more than the students in the control group. An increase in motivation and self-sufficiency of the students in the experimental group was identified as well. Thereafter, semi-structured interviews were carried out with students of the experimental group. It was found that they had positive opinions regarding the flipped classroom approach.

Flipped classroom is an active, student-centered approach that was formed to increase the quality of period within class. Generally this approach whose applications are done mostly in Physical Sciences, also attracts the attention of educators and researchers in different disciplines recently. Flipped classroom learning which wide-spreads rapidly in the world, is not well recognized in our country. That is why the aim of study is to attract attention to its potential in education field and provide to make it recognize more by educators and researchers. With this aim, in the study what flipped classroom approach is, flipped classroom technology models, its advantages and limitations were explained. Keywords: Flipped learning, flipped classroom, new approaches

Successful integration of mobile learning (m-learning) technologies in education primarily demands that teachers' perception of such technologies should be determined. Therefore, the perceptions of teachers are of great significance. There is no available instrument that assesses teachers' perceptions of m-learning. Our research provided the first findings about teacher perceptions in Cyprus. This article describes the development, testing and application for a suitable instrument. Research data for the tests of reliability and validity were obtained from a sample of 467 teachers from the 32 schools surveyed in 2010. The final version of the Mobile Learning Perception Scale includes dimensions seeking teachers' feedback on three facets of the m-learning. Sub-dimensions are defined as 'Aim-Mobile Technologies Fit', 'Appropriateness of Branch', and 'Forms of M-learning Application and Tools' Sufficient Adequacy of Communication'. Validity has been established by the use of factor analysis. Internal consistency coefficient and reliability of the scale showed that this instrument can be used for the future studies. According to the results of this study, teachers exhibited above medium levels of perception towards m-learning.
