當你在尋找研究主題並想辦法縮小範圍時,可以試著先廣泛的閱讀。在閱讀的過程中會幫助你了解此領域的專家使用了哪些關鍵字或術語,將這些關鍵字記錄下來,能減少之後找資料所花費的時間。這時候的閱讀可能會進一步縮小研究範圍,讓你更能聚焦主題內容。
例如你想了解肺部腫瘤對人體帶來的風險,開始進行背景知識閱讀。從閱讀過程中發現,該領域的專家學者通常使用lung tumor、lung neoplasm,而不是lung cancer 作為關鍵字。如果你單純使用lung cancer 作為關鍵字來查找資料,可能會錯過許多有用的資料來源。而且,用這些專家學者使用的關鍵字去查詢,表示查到的資料來源可信度會比較高,而不是一般新聞或商業、農場網站資訊。
哪些資源適合做為背景知識閱讀呢? 像是百科全書、字典、維基百科。
許多人遇到不了解的問題時,第一個反應就是問Google。維基百科通常都會出現在查詢結果中,但不建議依賴維基百科,因為它採協同合作,人人都可自由編輯,很難驗證編寫的作者是否對此主題有相當的專業或知識。不過,想要初步了解該主題或是每個條目底下的外部連結、參考文獻與延伸閱讀,可以作為資料查詢的參考。
圖書館訂購的Britannica School,可以輸入關鍵字(黃框)查詢想了解的主題,除了提供與該主題相關(紅框)的文章、影片與圖檔。亦有提供翻譯跟朗讀的功能(藍框),若想將文章儲存或是列印、email也可以。點選文章中的關鍵字可以連結到更多資訊。
It's wise to do some more reading about that narrower topic once you have it. For one reason, you probably don't know much about it yet. For another, such reading will help you learn the terms used by professionals and scholars who have studied your narrower topic. Those terms are certain to be helpful when you're looking for sources later, so jot them down or otherwise remember them.
For instance, if you were going to do research about the risks posed by lung cancer, this background reading would teach you that professionals and scholars often refer to the virus itself as lung tumor or lung neoplasm. If you didn't learn and use that in your eventual search for sources, you would miss the kinds of sources you'll need for your assignment—sources written by people in a position to know about lung cancer, unlike the general public.
What resources are suitable for background reading? Like encyclopedias, dictionaries, Wikipedia.
When people encounter a problem they don't understand, their first reaction is to ask Google. Wikipedia usually appears in query results, but it is not recommended to rely on Wikipedia because it is collaborative, and everyone can edit it freely. It is difficult to verify whether the author has considerable expertise or knowledge on the subject. However, if you want to have a preliminary understanding of the topic or access external links, references, and further reading under each entry, you can use it as a reference for data queries.
Britannica School, subscribed to by the library, you can enter keywords (in the yellow box) to search for the topic you want to know about. In addition to providing articles, videos, and pictures related to the topic (in the red box), it also offers translation and reading functions (in the blue box). If you want to save, print, or email the article, you can do so. Click on the keywords in the article to gain more information.
