Approaches to teaching history have significantly changed from being a linear subject laden with dates, timelines, and memorization to requiring a greater understanding thematically. Students are encouraged to make connections over time, continuity and change, the impact of technological advancement on society and industry, the peopling of the world, how previous events have future impacts on geopolitical relationships. Historic thinking is something that needs to be modeled and taught. Connecting the dots historically can be a daunting task with a tremendous amount of a priori knowledge, without knowing the basics it can be nearly impossible. To combat the issue of not having the necessary depth of knowledge, a simple solution can make all of the difference in the world. Creating a library of Primary Source Reader sets will allow students to quickly ascertain the most important documents and significant points of different historical time periods.
