<![CDATA[The formulation of the problem in this research is, is there an influence of the problem-based learning model assisted by the wall magazine learning media in history subject related to the Indonesian nation responses toward imperialism and colonialism on the critical thinking ability in XI IPS 4 class of SMA Negeri 5 Tasikmalaya academic year 2019/2020. The method utilized in this study is a quasi-experimental design. The population in this study were all XI IPS classes at SMA 5 Tasikmalaya with a total of 175 students.
