Abstract:  Curriculum 2013 recommended that the learning is done with a scientific approach.  The key to success of this approach student ability ask critical questioning. Some studies chemistry show students have difficulty questions (Katchevich & Hofstein, 2013; Eshach et al., 2014; Santoso, 2014). These problem can certainly reduce level activity in constructing their own knowledge based on what becoming for him. To overcome these problems, it necessary development inquiry involves asking...
