The ideal time (CH) recommended by students for field classes (AC), classroom (AS) and laboratory (AL) in teaching about soils at the fundamental (1G), second (2G) and higher (3G) levels was investigated in three schools of Cáceres and Cuiabá-MT, Brazil. We evaluated the effects of educational level of respondents on the CH indicated. There was a differential effect of schooling of the respondents on the CH recommended to AC and AS designed to 1G. For the CH class AC was greater than for AS and AL in all three education levels. Responders to more advanced school levels tend to suggest the reduction of CH for AC shown earlier school levels. We conclude that the classes on soils, at any grade level, according to students, should be developed in AC, AS and AL, using a different CH between classroom environments, predominantly AC. The results provide for the adjustment of time for teaching about soils.
