■ Why is "Extensive Reading" necessary for elementary school students now?
Nishimura-sensei states that the junior high school entrance exam is "an exam that requires the vocabulary of an adult from a 12-year-old child."
For elementary school students, Japanese language is still a language close to a "foreign language" that they are in the process of acquiring. "For children, solving difficult problems in an unfamiliar language is like reading a foreign language." The reality of junior high school entrance exams is that such children must face difficult exam questions that adults read.
Therefore, before embarking on serious exam preparation and before cramming "塾 techniques" (supplements), it is crucial to cultivate the "fundamental physical strength" to read long passages without stress. This is the shortest route to raising the deviation scores for all subjects, including not only Japanese language but also mathematics, science, and social studies, where long passages are a growing trend.
■ 3 reasons why professionals assert "Start by reading through this series"
The reasons why Nishimura-sensei recommends "Magic Tree House" as the "correct answer for building fundamental physical strength" are its thorough "readability" and "stability."
(1) Just the right difficulty, bridging "picture books and novels"
The font size and pacing of the text are calculated, making it easy for children without reading habits to achieve the sense of accomplishment of "I finished a whole book!" All kanji have furigana, allowing children to read on without stopping even if they encounter unfamiliar kanji.
(2) Easy-to-read content that opens the door to everyone
Unlike novelizations of popular anime or manga, this story requires no specific prior knowledge and has a universal plot that appeals to all genders and preferences. It's a story that all children can easily immerse themselves in.
(3) "Selection cost" is zero, thanks to the series volume and stability
The series currently has 54 volumes released. Since there are many, once children get hooked, parents don't have to bother searching for "the next book" every time, and children can choose and pick up the next volume themselves. The quality is also consistent throughout all volumes, so they won't get bored.
