Basic skill requirements for selected Army occupational training courses

This study investigated the basic cognitive skills soldiers must possess before entering the Army, skills that are needed for successful completion of entry-level training. Judgments of 126 instructors from 25 military occupational specialties were obtained on 129 candidate skills, which resulted in the identification of 55 basic skills. Factor analysis of these 55 skill items resulted in 11 interpretable factors. Mean scores on the factors were compared across factors and across Army training schools. The results of the study suggest that, for all occupational specialties studied, skills related to the learning process are as crucial as traditional academic skills for successful training course completion. These results have important implications for training for the Army as well as for industry.

浅议新课标下的异质学生最优化发展

有着学业水平差异的学生称作“异质学生”，异质学生的数学教学首先要使学生尽可能大地形成共性基础，应该让学生能得到最优化的发展。在新课标的指导下，数学教师在实施人文教育的同时，要针对异质学生的不同特点，在班级授课中形成独特的教材，这一教材应该是课本的同构体或异构体。教师要倡导自主学习，要发展地评价学生。
