[SUMMARY] The purpose of this study serves as a kick-starter to develop lesson units for authentic science for middle school science. These lessons were developed to deliver content knowledge with emphasis on elements of Nature of Science (NOS). This is a short-term study to research on the feasibility of such lesson units in teaching both content and NOS explicitly. The topics selected for development are Chemical Reactions and Atoms & Molecules respectively. The series of lessons were conducted with two classes of 8th Grade Japanese students. Data, both qualitative and quantitative, was collected through a few ways: lesson observations to assess the viability of the lesson; pre- and post-test to evaluate students’ understanding of NOS; and questionnaire to gather students’ perceptions of the lesson. From the observations of the classes, students were engaged in carrying out the activities to elicit NOS elements. In addition, from the results of the pre-test and post-test, there was an improvement in the understanding of elements of NOS. Furthermore, from the results of the questionnaire, the lesson units were well-received by the students and students were able to learn both content and elements of NOS. These results showed promise in the teaching both syllabus content and elements of NOS in an authentic context.

[要約] 本研究の目的は，理科の深い学びの促進を指向して，科学的リテラシーに含まれるNature of Science（NOS，科学の性質）の要素を強調した授業を開発すること，及びその開発した授業を評価することである。中学２年生の「化学変化」と「原子・分子」の２つの単元を題材として，それぞれ，科学的知識の可変性，科学的知識の創出における創造性の重要性という，NOSの要素を強調する授業を開発した。主に，当該授業についての感想，授業前後の生徒のNOSの理解度が，質問紙によって問われた。分析の結果，NOSの要素を理科の内容領域の指導に組み込むことで，NOSの理解度の向上に加え，理科の内容についての深い学びを促進できる可能性が示唆された。
