Research on the instruction of summarization and its assessment

The ability to accurately and concisely convey information that has been heard or read is an important ability in our daily lives. However, reporting information word for word is impossible due to the limited capacity of working memory. To summarize the information, we carry out the mental operation of compressing it as much as possible, and we express the information by speaking or writing in our own words.
I have been engaged in English education for many years, so my research interest is in the application to English education. Summary writing is considered an essential element of academic literacy in studying English as a Foreign Language (EFL). However, it is also recognized as difficult to learn because it requires abilities such as reading comprehension and writing in English, as well as the skill to organize information, and metacognitive competence. Since the evaluation of this complex summarization ability involves measurement of various skills and abilities, it is essential to verify its reliability and validity. I am studying effective instruction of summarization in English education and evaluation of summary writing that is practical, reliable, and valid for English teachers.
