施用NPK肥对高梁杂交草吸收Cu的影响

采用盆栽试验,研究了施用NPK肥料对高粱杂交草吸收微量营养元素Cu的影响.结果表明,各处理Cu的吸收量大小的顺序依次为NPK＞NP＞NK＞N＞P＞K＞CK＞PK;各处理高粱杂交草体内Cu浓度的变幅是24.7～39.8μg/g;N是影响高粱杂交草吸收Cu的主导因子,由于稀释效应,施N处理的高粱杂交草体内Cu的浓度相对较低.

This commentary discusses reasons that lead scholars to feel entitled to make judgements in areas where they have little or no expertise. Three current reports about the future of online learning are considered, issued by the Global Learning Council, Massachusetts Institute of Technology, and the Gates Foundation. Two of these publications contain contradictions and confusion that may simply be due to lack of awareness of distance education (DE) and online learning research. The third report gives good evidence but has been criticized for being too academic. The conflicting standards and criteria evident in such writings may be due to institutional pressures to promote policies and principles despite lack of supportive evidence, and to weaknesses in the DE literature itself. As major institutional policies about online learning are likely to be based on the recommendations of such reports, it is important for DE specialists to challenge them where appropriate.     

Separating arguments from conclusions: the mistaken role of effect size in educational policy research

ABSTRACT

Effect size is the basis of much evidence-based education policymaking. In particular, it is assumed to measure the educational effectiveness of interventions. Policy is being driven by the influential work of John Hattie, the Education Endowment Foundation, and others, which is grounded in this assumption. This article demonstrates the assumption is false and notes that, when criticized, proponents either attempt to inoculate themselves by listing (without checking) assumptions or use the specious reasoning that, however flawed their argument, no-one has disproved their conclusions.
