Try this:

(defun scheme-output-to-minibuffer (string)
  (let* ((string (let ((prompt (format "%s\\'" comint-prompt-regexp)))
                   (if (string-match prompt string)
                       (subseq string 0 (match-beginning 0))
                       string)))
         (string (if (string-match "\\`[\n\t ]*\\(.*[^\n\t ]\\)[\n\t ]*\\'" 
string)
                     (match-string 1 string)
                     string)))
    (message "%s" string)))


(add-hook 'inferior-scheme-mode-hook
          (lambda () (pushnew 'scheme-output-to-minibuffer
                               comint-output-filter-functions)))

The fundamental essence of emacs is that you may change its behavior
if you don't like it.  You can do that by modifying customization
variables, try: M-x customize-group RET scheme RET and see if there is
an option to send scheme output to the minibuffer; or by modifying the
emacs program itself, writing emacs lisp code.  If you don't have a
customization option to do what you want, and you don't want to write
emacs lisp code, then the answer is that emacs cannot do what you
want.  Perhaps you should try another IDE.  PLT-scheme comes with a
nice IDE.
