PTT托福板友們大家好，
我是SK2 TOEFL實力養成班教學顧問Vivian.
9月是暑假完成課程同學們首戰托福的重要月份，
若距離考試剩2-3週，我會叮嚀大家要開始練習計時的臨場感。
ETS因應新制托福上路開發了一些不錯的工具，
其中寫作Task 2有非常接近正式考試UI的介面可以練官方釋出的練習題與計時，
更能使用AI Rater評分作文。
Task 2練習介面在這裡：
https://www.ets.org/toefl/test-takers/ibt/prepare/practice-tests.html
近日有很多認真的學生拿AI評估的結果與我討論，
我們來看看不同分數區間的差異：
題目：
Which approach do you think is better:
Giving grades based only on performance, or grading students not just on
performance but also on their effort?
以下為學生10分鐘內寫完的版本；可能有under timed conditions的typo.
(AI Score: 4.0)
In my opinion, Kelly is right when she said that a perfromance
based evaluation is more reasonable. It is by far the most
efficient and recognizable way of grading, consider evaluating
ones effort is abstract and time-consuming. I'd added that
students' effort will show on their grades under most of the
conditions. On the contrary, when a student doesn't really put
effort into their work, their performance will definitely have
many errors. When a hard-working student spend hours on
assignments or tests to completely figure out what are the core
comcept and correct answer, they can get good performance easily
based on their hard work. That is to say, I think evaluating with
performance without considering effort is fair and benefits
students learning curve. Other than considering students' side, it
is more managable for teacher to grade students based on
identical criteria that is quantfiable.
再來是修改過後的版本，這次AI給Score of 5.0:
In my opinion, Kelly is right when she said that a perfromance
based evaluation is more reasonable. It is by far the most common
way of grading, consider evaluating ones effort is time-consuming
and hard to quantifiable. I'd added that students' effort will
show on their grades under most of the conditions. When a
hard-working student spend hours on assignments to completely
figure out the concepts and tips on finishing it, they can get
good result easily based on their what they've learned. On the
contrary, when students don't really put effort into works, their
result would have many errors and they don't really learn stuff.
For example, I usually start preparing for an exam 2 weeks before,
but once I forgot to mark an upcoming exam on my calander. The
time that I found out and started to study was 3 days before it.
Not having enough preparation bought me terrible result on that
exam, for sure. To sum up, I think grading without counting effort
is fair and resonable.
不知道同學們看不看得出來兩個版本的差異呢？
ETS在相同網頁中提供了scoring guide給大家參考：
4.0-5.0區間：
You made a well-supported, relevant contribution to the discussion,
and your ideas are easy to understand.
Weaknesses, if there are any, might have to do with:
-use of English that is occasionally ungrammatical, unclear or unidiomatic
-the elaboration of your viewpoint needing a little more detail or explanation
以上內容兩者最大不同是，5.0的版本多了「舉例」，
而且其中兩句重新排列，使邏輯較為通順。
AI是根據ETS公布的標準評分的，
因此所有考生應該都要對於Rubrics瞭若指掌：
https://www.ets.org/pdfs/toefl/toefl-ibt-writing-rubrics-enhanced.pdf
換句話說，只要充分了解題目的requirements與評分rubrics標準，
同學們將對練習方向會清楚不少。
當然ETS最後給分還要經過人工審核，
所以同學們使用這個AI工具只能當成初步分析自我表現的工具；
詳細的feedback（是否切題、更進一步的改善建議）
還是要由有經驗的老師們給予。
