At the same time, the standardization of the teaching process appears to be insufficient to meet the modern instructive requirements, while it is vastly supported that differentiated teaching can sufficiently respond to the modern instructive needs. Moreover, it is pointed out that differentiated teaching is another way of thinking on the instructive work. On that basis and with a view to investigating the functionalist dimensions of differentiated teaching, a research of empiric character was attempted geared toward at the investigation of attitudes and opinions of Greek primary school teachers with regard to the differentiated teaching. The structured questionnaire was used as a research tool and the main conclusions showed not only the limited briefing of the sample teachers, with regard to the theoretical and applicable functionalism of differentiated teaching, but also the conviction that the differentiated teaching has the potential to treat students equally while functioning as a driving force for the dynamic forming of knowledge by the students themselves.展开更多

This real potential is determined by identifying 10 biomass samples taken from vegetable resources which are favored by their aptitude of adaptation to the conditions of Iran. The net energy values of the 10 biomass samples change in the range of 13.65-18.00 MJ/kg using bomb calorimeter. By means of least squarere regression method all correlations were found. The results of 10 different biomass materials have been used to develop a linear equation correlation.展开更多
