      个人学习可能取决于他人行为的主张突出了将学习环境视为一个涉及多个互动参与者的系统的重要性
      When it comes to learning context, what reminds me is the personalized learning context theory. Stephen Dowens (2010) pointed out that the learning context is a loose collection of learners, tools, resources and services, which is also a new form of the network power utilization. In a personalized learning context, there is undoubtedly that learners are the main body who participating in the teaching and learning activities. We can assume that in a passive process like listening to instructor’s point without learner’s interaction, it’s hard for learners to improve their creativity and learning efficiency. Many online learning environment designers create discussion forums in the learning system to record learners' interactions with other leaners, such as questions they ask and the responses to others' questions. The system can capture learners' study related data, analyze and assess their cognitive levels using algorithms such as the Proficiency Model.

      Calculations of Σ are unfortunately very difficult even for the electrongas. We must resort to approximations and this review describes theGWapproximation (GWA)(Hedin 1965a) which is the simplest working approximation beyond the HFA that takes screeninginto account.

      This is a good explanation of what GW really does. It calculates the self energy.
