About laravel eloquent - how to get specified column value in database

i'm new to Laravel, i'm using laravel 5.1 I want to get the specified column in the database.

It's my controller:

public function index()
{
    $markQuizs = MarkAss::select('year')->where('user_id','=','abc001')->get();
    return view('marks-management', ['markQuizs'=> $markQuizs]);
}

In the view page, i try to echo

$markQuizs

but it got

[{"year":2016}]

how can i only get the "2016" value? Does it need ajax?
