I really don't understand this sentence meaning, anyone knows?

> On the other hand, by focusing on evaluating lessons which students weak(?),
> teacher who has popularity who cheapening grades

Can you give me advice how to understand Japanese long sentences? Although
sometimes I know the meaning of each kanji and words but when it comes in a
sentence, sometimes I don't get the main point of the sentence and becomes
more ambiguous.




>
> 「[他方]{たほう}、[成績評価]{せいせきひょうか}の[甘]{あま}い[授業]{じゅぎょう}が[高]{たか}く[評価]{ひょうか}されたり、[人気取]{にんきと}りに[走]{はし}る[教師]{きょうし}が[出]{で}たりし、[成績]{せいせき}の[安売]{やすう}りや[大学教師]{だいがくきょうし}のレベルダウンという[弊害]{へいがい}をもたらす[恐]{おそ}れがある、などの[反省意見]{はんせいいけん}もある。」

As far as grammar and structure, this is actually a pretty straightforward-
looking sentence with no 'tricks or traps'. As long as you REALLY know the
meaning of each word ( ** _and have a feeling for them_** ), there should be
no problem understanding the sentence.

The basic structure of this sentence is:

> The general statement: "On the other hand, there also are reflective
> opinions." （「他方」 and 「などの反省意見もある」）

Just in case you did not realize, the rest of the sentence is only an
'explanation with examples' of that general statement.

↓

> An example of a possible negative effect leading to a reflective opinion.
> （「成績の安売りや大学教師のレベルダウンという弊害をもたらす恐れがある」）

↓

> Two example causes to the possible negative effect above.
> （「成績評価の甘い授業が高く評価されたり」 and 「人気取りに走る教師が出たりし」）

My own translation attempt:

> "On the other hand, there also exist some reflective opinions. One such
> opinion is that because the classes (courses) where student evaluation is
> not strict could be rated highly (by the students), or because some
> instructors might blindly seek popularity, there is a fear that those events
> might bring a harmful influence such as easy grade bumping and the general
> decline in the standard of university instructors."
