Educology: The theory of educational practice

The relationship between psychology and education may be expressed in terms of two general models: the traditional hierarchical model, according to which psychology is the “parent” discipline; and a parallel model, in which the relationship between “pure” theory and its application is metaphoric rather than paradigmatic. The hierarchical model, however, does not hold even for such a “tight” area as behavior modification, let alone for educational practice in general.Educational practice, as a professional enterprise, should be guided by a consistent set of constructs taken from the practitioner's universe of discourse. The professionalization of education has been delayed because of attempts, mostly vain, to guide practice by applying constructs derived from other disciplines. Other disciplines, notably psychology, can be useful for education but in a metaphoric sense only. “Educology” is suggested as a convenient term for the set of constructs that should give coherence to educational decision-making.     

Student commitment and school organization in relation to on-task behavior and achievement

Three experiments considered student commitment to school, IQ, and school organization type in relation to student task behavior and to school achievement. The first two correlational studies indicated the relationship between student commitment and student task behavior; the third study used student task behavior, student commitment, IQ, and school organization to predict achievement. This prediction equation was quite robust with a final R² = .85. School achievement is predicted by intelligence and academic time on task in traditionally structured schools, and by intelligence and student commitment in open structured schools. Increasing the amount of teacher directed time would increase achievement in traditional schools, but decrease achievement in open schools.

甘蓝和芥蓝的核型与孢粉学研究

 本文通过对甘蓝和芥蓝的核型分析和花粉形态的扫描电镜观察，认为它们的核型并不完全一致，而花粉形态的明显区别说明芥蓝是一个独立的种，与芸苔属其他种不很亲缘。
