The present study aims at investigating the efficacy of blended learning in distance education on educational performance of 7th grade secondary school students in the lesson of art in Gonabad city. The research method is quasi experimental with post-test, pre-test and control group design. The statistical population consists of all female students in the 7th grad secondary school in Gonabad city who were studying in the academic year of 2016-2017. The research sample was 58 participants selected through available sampling and assigned into two experimental and control groups who were homogeneous based on educational achievement. The experimental group was given instruction based on blended learning system and the control group was under traditional teaching style. The pre-test of educational performance of the lesson of art was performed on both experimental and control groups and after 12 instruction sessions in blended learning to experimental group, the post-test of educational performance in art was administered among both groups. The results were analyzed using Covariance Analysis in SPSS software. The findings indicated that the educational performance of experimental group in Iranian painting, designing applicable objects based on fruit and flower patterns, new ideas and new pattern of objects, and educational performance in regular design textures have been enhanced and there was a significant difference between educational performance of experimental and control groups in art lessons with a higher achievement of experimental group. 

This research was conducted with the aim of investigating the role of digital leadership and technology flexibility in intelligent decision-making with the mediation of intellectual ethics and team reception. The research method is quantitative, descriptive and of the type of correlation studies based on the covariance-oriented structural equation modeling approach. The research population was all the elementary principals of Kermanshah province, of those 320 principals were selected through stratified random sampling based on Cochran's formula. To collect data, researcher-made questionnaires of digital leadership, technological flexibility, intelligent decision-making, intellectual ethics and team reception Soltani (2008) were used.

The reliability of the questionnaires according to Cronbach's Alpha was 0.94 for digital leadership, 0.91 for technology flexibility, 0.95 for intelligent decision making, 0.93 for intellectual ethics, and 0.89 for team reception.  To analyze the data, the descriptive as well as inferential analysis techniques were used through SPSS and LISREL software. Structural equation modeling showed that digital leadership has a direct effect on team reception, intellectual ethics and intelligent decision making. Moreover, digital leadership has an indirect effect on intelligent decision-making through team reception and intellectual ethics. The flexibility of technology has a direct impact on intellectual ethics, team reception and intelligent decision making.
