hint #1
spelling is wrong here: resul_array();

Which version of CodeIgniter are you using? It sounds like a UCfirst problem if using CI3.

Codeigniter 3.0.6.. I am using this version of Codeigniter

Using 3.x, your controller & model filenames need to be UCfirst, eg controllers/Cuzdan.php and models/Cuzdan_model.php
If they aren't, then CodeIgniter will not find the model, and $this->cuzdan_model will be null, which will produce the error message you described.

my model name is such...
class Cuzdan_Model extends CI_Model{
....
}

after I did like you said...
class Cuzdan_Model extends UC_Model{
....
}

but it didnt work again

The function in your model isn't returning anything, so the controller doesn't get anything to work with.
Replace the function with this:

PHP Code:

public function getParaHareketleri($islem)
{

  $query = $this->db->select("*")
  ->from("parahareketleri")
  ->where("islem", $islem)
  ->get();
  if ($query->num_rows() > 0 ) {
     return $query->result_array();
  }
  else {
     return array();
  }

} 


Nothing is changed

This is my controller..

Did you change the php file name to:
models/Cuzdan_Model.php
