In the age of information explosion, self-study plans, multidisciplinary knowledge, and learning advice have become crucial for K12 students. Effective self-directed learning can help students build a knowledge network across various fields such as world trade, history, and science.

Setting Clear Self-study Goals
Before starting a self-study journey, students need to set clear goals. For example, if a student is interested in world trade, they can set a goal to understand the basic principles of international trade within a month. This provides direction and motivation for their learning. International Trade on Britannica
Building a Multidisciplinary Knowledge Base
To gain a comprehensive understanding of different subjects, students should explore multiple disciplines. History can offer insights into the development of trade over time, while science can contribute to understanding the technological aspects that influence trade.

By integrating knowledge from various fields, students can develop a more profound perspective. Multidisciplinary Approach on Wikipedia
When it comes to learning advice, students should adopt a systematic approach. They can break down large topics into smaller sub-topics and study them one by one. Regular review and summarization are also essential to reinforce learning. Additionally, using various resources such as online courses, documentaries, and books can enrich the learning experience.
Readability guidance: Use short paragraphs and lists to summarize key points; provide a list under each H2 whenever possible; control the proportion of passive voice and long sentences; add transition words (however/therefore/in addition/for example/as a result, etc.) throughout the text.
