I tried to connect the stepper motor with the driver board but when I went to grab the battery it nearly burnt me. I connect IN1-4 to the digital pins on the Arduino , and the 9v battery directly to the positive and negative of the driver board .What could I be doing wrong ?
You are drawing way too much current from the little 9V battery. They are not intended to run a motor.

Its a 28BYJ-48 motor I thought they could handle it?
Assuming the "9v battery" is the little rectangular type - the motor is what the motor is, the battery is not up to the task.
Odd that it gets hot, though: discontinue use.
A schematic or wiring diagram would help a lot here.
Be careful about plugging an Ardino into USB and the power plug or Vin at the same time. Some Arduinos have protection circuitry and some don't. I can't keep track which is which so I do t do it. Use o e or the other to power the circuit.

[edit] While reading about variations of internal resistance of the PP3 (inconclusive), I found this interesting "uses" quote...
In the American prison system inmates have even been known to utilize the 9 volt battery to light cigarettes by adding a steel wool or wire to create an ultra hot contact point. This is not recommended (link)
Is the world not incarcerating engineers? I use a AA. Cheaper and longer lasting.

which so I don't do it. Use one or the other to power the circuit.
