An analytic review on blended learning effects on students achievements in learning science

The world of communication in the third wave of communication approaches has brought a new way of life in the form of new tools, which has led to it being called the electronic hut. Rapid developments resulting from the application of technology, including productive technology and information technology in human life have caused dramatic changes in the industrial, economic, political and civil structures of societies, and these changes have had a significant impact on the life and work of people around the world. It has seriously challenged traditional methods of teaching, learning, and managing education. With the help of new educational tools, there is an opportunity to make new choices to combine the knowledge of students and students, including the use of blended teaching methods in an environment based on e-learning technology. Blended instruction is the preparation of an active environment and the introduction of dynamic training methods through which it is possible to use educational facilities with its minimum and maximum benefits. In this environment, it is possible to move from face-to-face learning to combining it with virtual classes and finally using fully online facilities. Blended learning as a new paradigm in educational context undergrounded in using ICT when learning occurs both in the classroom and online situation. The paper explains students' achievement in learning science through blended method at a secondary school in a city in Iran.

Method and Materials:

 Research sample includes 160 students in 6 classes and in 3 grades. 60 of learners after revising of their pre - test score on the basis of scores' variances randomized as control and experimental group.30 of them considered as experimental group learned in blended method and the same sample participated as control in classic styles of learning. Data were analyzed by T test and covariance analysis.

Findings showed that blended learning method could promote achievement results in experimental group on learning science conceptions.

Learning is formed with a blended approach based on activity-based principles and the learner is required to reflect and decide on events and facts online or offline and explain the reality by reflecting group or individual processes effective in problem solving or decision-making, reviewing the solution and reviewing the effective feedback on solving the problem. Using the teaching method in a blended way and in fact combining education by using the computer as a powerful medium in the learning and teaching processes in addition to improving the teaching of science concepts, after direct teaching in the classroom and in combination with the curriculum assignments related to daily life, can be effective in improving the learning of learners.
