教育研究之“问题”研究——兼论质疑教育

何谓问题?何谓教育问题?对教育“问题”的追本溯源,是教育研究的逻辑起点,而“真问题”亦为引发研究问题的矛盾所在,并非矛盾的表现形式。基于表形外壳的问题研究,实为问题研究的迷失,导致教育研究的畸形发展。例如,目前人文社科类研究生研究的“问题”多止步于表形外壳层面,少数研究深入到构因内核,还有部分研究游离于矛盾之外。因此,需要开展质疑教育,研究教育问题与教育理论、教育实践的关系,探寻能够反映矛盾构因内核的“真问题”,并构建基于“真问题”的质疑教育框架,为教育研究提质增效提供新的路向。

Rice Husk Ash:A New Silicon Source for Preparing SAPO-34 Catalysts Used in the Methanol-to-Olefins Reaction

SAPO-34 molecular sieves were synthesized directly by hydrothermal method with rice husk ash(RHA)used as the silicon source.The crystal structure,composition,surface morphology and acidity of the synthesized products weresieves had a high crystallinity,without any impure phase.Compared with the SAPO-34 prepared by the silica sol,RHA-SAPO-34 had similar acid properties in strength.The methanol to olefins(MTO)experiments showed that the SAPO-34molecular sieve synthesized from RHA exhibited both a good catalytic activity and ethylene selectivity.
