II.4.9 The Development of the Language Ability
of School Children
(Report 26, 1964. 604 pages)
The previous four reports were, so to speak,
interim reports issued during our survey of the development
of language ability. Surveys of listening and abilities have
also been reported in the Annual Reports. This book is a
collection of the above data, rearranged in order to see the
development afresh and as a whole after the 7 years of
follow-up studies. We tried not to repeat subjects described
enough in the interim reports (e.g., the development of home
reading). Some are quoted, however, regardless of
repetition, out of necessity.
In the first chapter, we explain the characteristics
and system of this survey and examine the results which led us to
our conclusions. In the second chapter we examine, generally
and relationally, the interrelation between language abilities
and the factors of development from two angles: the
development, year by year, of the interrelation between
language abilities and the factors of development, and the
developmental interrelation, term by term, of the same
language ability. In the third chapter we survey the conditions
of learning each language element, writing, orthography,
grammar, and vocabulary. We also investigate the steps and
form of development and problems to be solved. In the fourth
chapter we describe the steps and phenomena of the development
of language skills, reading and understanding skills (including
reading speed), composition, speaking and aural comprehension.
On the whole, in this report the outline and results of
the survey are first described, followed by concrete minute
data which support the results. Therefore, this report is
much easier to read than the previous publications of this
series.
In the last chapter, the fifth chapter, we report a case
study of the growth of four children. The development of
their language ability during the six-year survey represent
several models.
The characteristics of this survey are:
1. Some methods of examination in language ability are
newly contrived.
2. The tendency of the development of each language
ability, such as aural comprehension, speaking, reading,
writing, vocabulary or grammar, is discovered.
3. The factors of development are made clear.
4. The average ability of each grade is discovered.
This six-year survey was made by KOSIMIZU Minoru,
ASIZAWA Setu, and MURAISI Syo~zo~(throughout the period), and
by TAKAHASI Taro~, ZYOKO Kan'iti, MORIOKA Kenzi, and OKAMOTO
Keiroku. This report was written by KOSIMIZU, ASIZAWA,
TAKAHASI and MURAISI.
