Modul Ajar Bahasa Inggris Kelas 12 SMA: Scientific Manuals and Technical Instructions (Procedure) (Bab 5)
Technical and scientific procedural manuals, operational instructions, safety warnings, imperative mood, modal verbs of precaution (must, ensure, avoid), and troubleshooting protocols in laboratory and engineering contexts.
Capaian dan tujuan pembelajaran
Peserta didik mampu menganalisis struktur dan bahasa instruksional dalam manual teknis ilmiah.
Peserta didik mampu menggunakan kalimat imperatif dan modalitas kehati-hatian dalam teks prosedur.
Peserta didik mampu menyusun manual prosedur teknis dan panduan pemecahan masalah (troubleshooting) yang akurat.
Materi pokok & uraian konsep pembelajaran
Technical procedure texts provide precise, sequential instructions guiding users through complex operations—such as calibrating laboratory spectrophotometers, operating 3D printers, or deploying robotic software frameworks. Precision and clarity prevent operational hazards.
The anatomy of a technical manual encompasses: Goal/Objective (defining the task), Required Equipment/Materials (specifying calibrated apparatus and safety gear), Step-by-Step Instructions (imperative action steps), Safety Warnings (*Caution / Danger notes*), and Troubleshooting Matrices.
Linguistic features include concise imperative sentences (*insert, calibrate, tighten*), sequencing adverbs, precise technical terminology, and precautionary modal verbs (*must be grounded, ensure that...*).
