REFLEKSI
Hari ini, Pn. Zakiah telah menasihati kami supaya banyak bertanya di dalam kuliah kerana “a good classroom is where the students talk much more than the teacher”. Pelajar yang rajin bertanya akan mendapatkan maklumat yang dikehendaki. Selain itu, pelajar menunjukkan minat yang lebih dalam mendengar apa-apa yang disuarakan oleh rakan daripada mendengar apa yang disampaikan oleh guru. Di samping itu, saya mendapati bahawa setiap kali kalau network komputer saya terputus, bahan-bahan yang sedang dicari dapat dikembalikan pada masa network disambungkan kerana komputer akan menyimpan maklumat tersebut dalam jangka masa yang tertentu. Pn. Zakiah juga memberitahu kami tentang real time software, iaitu contohnya Skype yang membolehkan seorang rakan berkomunikasi dengan seorang rakan pada masa yang sama. Saya lebih mengenai apa-apa yang terkandung dalam subjek TMK dan saya berasa waktu ini merupakan peluang keemasan untuk saya menambahkan pengetahuan yang banyak tentang TMK.
