圖書資訊學概論 11/01 (James)

開始準備使用Black Board http://elearning.ntnu.edu.tw/

這次討論的主題為是EBL (Evidence Based Librarianship)。

EBL's 5 steps:
1. Define Problem (解釋問題)
2. Find Evidence (找出證據)
3. Appraise Evidence (評估證據)
4. Apply Results of Appraisal (由結果評估)
5. Evaluate Change (變化評估)
6. Redefine Problem (Booth and Brice, 2003) (再對問題加以說明)


Evidence Summary: Undergraduates Prefer Federated Searching to Searching Databases Individually

Abstract: 大學能寧願使用meta-Research，也不想使用個別的DB，理由是為了節省時間去找需要的資訊。

Case Design: Crossover study (交叉學習)

Setting: 3 Colleges in USA，利用各大學的學生的使用習性做觀查

Main Results:
1. 70%的參與者喜歡使用 Meta-Research。
2. 三間大學得到的數據也差不多。
3. 使用 Meta-Research 找到所需資料，所發費的時間約為20.34 Mins。
4. 使用個別的DB去找到資料，所發費的時間約為20.72Mins。
5. 查詢率：使用 Meta-Research 為5.59/7；而使用個別的DB為4.80/7。

Conclusion: 學生較使用 Meta-Research ，且找到的資料也比較滿意、也較省時。


發表的意見為：
From this case, there are seventy precent users preferred meta-search. But, there are a little difference between meta-search and non-meta-search.

So, we could think some thing in this case.
1. Should we use the meta-search? (For user)
2. Should we buy the meta-search? (For Library)

I'm agree Professor Pu's suggestion that undergraduate shouldn't use the meta-search. Because they would get too many informations and couldn't find what they are.

In our Academia Sinica in Taiwan, our libraries would like to buy the meta-search. But we had found some question for meta-search.
1. Too expensive.
2. There are some DB couldn't been used with meta-search. For example, the DB must been used the UserID and PW.
3. The statistic for use DB that couldn't been used. Because I use the meta-search, all of DB would been counted one time.
