In our point of view, however, explicit and intensive instruction is necessary.
This finding is consistent with a study of Luke, Rahim, Koh, Lau, Ismail and Hogan (2005) that grade 5 (primary 5) and grade 8 (secondary 2) science teachers were predominantly using teacher-centered inquiry-based teaching practices even though they knew student-centered instruction was necessary for students' learning.
The appeal to tradition (oral instruction) is necessary, Mendelssohn adds, given the fact that, over the course of time, the laws themselves become unintelligible "since no words or letters retain their sense unchanged from one generation to the next" (Jerusalem (1983), p. 128 (translation slightly altered)/Gesammelte Schriften 8, p. 193).
No instruction was necessary.
Carefully designed instruction is necessary to help students replace misconceptions with scientifically supported conceptions.
The study also demonstrated that careful patient instruction is necessary including demonstration and practice measurements with the help of a mirror.
Supervision is also easy in case of mass production because only few instructions are necessary.
Therefore, frequent follow-up and clear patient instructions are necessary for safe expectant management.
Getting Started The system is intuitive and easy to use, and no instructions are necessary to get started.
The subjects were instructed that, when using Pseudo-Joystick control they should occasionally look back to check the robot's position; these additional instructions were necessary since early tests had shown that without glancing back it was almost impossible to avoid obstacles.
