Furthermore, what had made this textbook thorny to
teachers was that they had to merely cope with the corpus of the textbook. They did
not find any testing suggestions, teachers' manual, and adequate review sections,
i.e. the textbook merely employs two review parts: review exercises (1) and review
exercises (2). The former refreshes the contents of the second grade textbook and
the latter covers all chapters' paramount points through eight parts (from A to H).
What had made the review sections inadequate, looking through teachers' glasses,
was that there were not found single review for each chapter concentrating on its
contents (based on figure 2).
