SQL & PL/SQL :: Create A Procedure Using EXECUTE IMMEDIATE?

I am trying to create a procedure using the EXECUTE IMMEDIATE. I have been having problems calling it from an anonymous block

My code

CREATE OR REPLACE PROCEDURE homework
(p_table_name VARCHAR2)
IS
v_department_id departments.department_id%TYPE;
BEGIN
EXECUTE IMMEDIATE

[code]....

I called the procedure from an anonymous block

BEGIN
homework('Employees');
END;

It gives me an error

ORA-00905: missing keyword
