STEM Field Trips Take STEM Education to New Heights Over 400,000 students and more than 15,000 organizations have participated in the iFLY STEM Program. Our STEM program inspires and educates students through an immersive, educational program where they first learn science and technology, and then...
为M个field的特征,分别有共享的emb table ES∈RN×K 和任务特定的emb table Et∈RN×K ,N为所有field中的特征数,K为emb维度。则每个field的特征我们都可以得到:vti=Lookup(xi,Et)vSi=Lookup(xi,ES) 将所有特征的emb拼接得到ht0=[vt0,...,vtM]hS0=[vS0,...,vSM] 2.2 共享的和任务特定的专家网络 ...
在STEM教育中,Krajcik和Blumenfield提出了基于项目的学习的几个关键特征[7]。 驱动问题基于项目的学习的核心在于解答一个驱动问题。驱动问题包含了具有价值且意义深远的内容,并紧密联系着现实世界的具体情境[9]。这些驱动问题应以学生的个人经验为基础,并与所期望的学习成果(例如学习标准)相关联。驱动问题之所以有意义且...
图6. EELS 软件自动分析结果 3 Z衬度像/HAADF-STEM像Z衬度像/HAADF-STEM 像( Z-contrast Imaging/ High angle annular dark field image,HAADF)20 世纪 90 年代以来,随着电镜硬件的不断发展,尤其是具有场发射电子枪的超高真空电镜的出现和普及,一种高分辨扫描透射成像技术,即高分辨或原子分辨率的原子序数( Z...
STEM-identity, i.e., the internalized idea that one belongs to the STEM field they have chosen to follow22, may reduce the consequences of stereotype threat and psychosocial issues23. This identity can be stimulated during the different career stages through mentorship. Thus, mentors play a ...
Anew paperby Colorado State University researchers shows that calculus is 1.5 times more likely to discourage women than men from continuing on in their chosen STEM field – not because of their ability, but because of confidence in their ability. ...

1973年,Humphreys等人首次提出高角环形暗场( high angle annular dark field, HAADF )探测器的概念,并指出,当环形暗场探测器内角增加到更高角度后, 图像的衬度将不再是与原子序数 Z成正比,而是大约与Z的平方成正比,因此 高角环形暗 9、场像也被称为Z衬度像(Z contrast image)。在扫描透射电子显微镜 中最...
"Stem cells have enormous potential for alleviating suffering for many diseases which currently have no effective therapy. The field has progressed to the clinic and it is important that this pathway is underpinned by excellent science and rigorous standards of clinical research. The journal provides ...
