The first-year students asked why Big Y and Big W were special.

Y and W are two special letters, which are a difficult point in pinyin teaching in primary schools.

In the previous textbooks, Y and W were taught after initials, which misled teachers and students and thought that Y and W were initials.

Nowadays, the new textbooks put Y and W together with monosyllables I and U, which essentially shows that they are not initials, but appear in front of I and U for the needs of spelling rules. They are another writing form of "I and U" and play an auxiliary role.

But it is quite complicated to tell these rules to first-year students.

When teaching this course, teachers must be flexible and reduce the difficulty.

They are difficult, and the first difficulty lies in the topic.

They read Y, W, and not the capitals of the single vowels I and U, because they will teach students that the capitals of I and U are I and U in the later dictionary teaching.

But in order to make it clear in class, teachers call them big y and big w, which makes it easy for students to confuse capitalized I and u.

The second difficulty lies in its function.

Y and W are two letters that play a sound insulation role in the Chinese phonetic alphabet scheme.

In the teaching process, teachers can temporarily treat these two initials as initials, which is based on the cognitive ability of first-year students, so that they can teach less complicated spelling rules and reduce the learning difficulty.

In teaching, Y and W are combined with the whole syllables Yi and Wu, and students can learn about I and U through short stories. When they are syllables, y and w should be added before them, which leads to the whole syllable.

Syllables that begin with "y, w" can only be regarded as zero initials (syllables without initials)

In the specific teaching implementation process, teachers can adopt the following methods to solve this difficulty.
