AbstractDesigning problems and learning activities is a key factor to initiating students’ engagement with the course material and influencing their reasoning processes. Although tasks and problems are a central part of teaching and assessments in the chemistry classroom, they may not engage students in deep reasoning or in a way that is intended through a task. Some problems may cause an algorithmic or a surface approach. Even with designing clever problems, students may not use a larger variety of chemistry ideas and connect them in meaningful ways. Here the idea of scaffolding students’ answering process comes into play. Structuring students’ reasoning process through instructional prompts or structured worksheets supports students in activating and connecting knowledge pieces in a more meaningful way and positively slows down their fast decision-making process. This paper will discuss the importance of asking questions in chemistry teaching and highlights the idea of contrasting cases, drawn from cognitive psychology, as a task design principle. In addition to having contrasting cases as a good problem format, the idea of scaffolding students’ reasoning while solving contrasting cases through the use of instructional prompts that scaffold the reasoning process will be exemplarily showcased for mechanistic reasoning in organic chemistry.

Development Of Students

This study examines scientific practices associated with scientific writing in organic chemistry in China. Although there is rapidly growing literature on the features and strategies of scientific writing, further research in this area is needed to recognize and treat scientific writing as a social endeavor to evaluate it in a more comprehensive and detailed way in order to effectively convey scientific information to readers. This study shared these important premises and attempted to investigate the development of Chinese undergraduate students’ competence of scientific writing. Twenty-two undergraduate students majoring in chemistry participated in this study. They experienced a researcher-intervenedAdvanced Organic Chemistry Experimentcourse and were asked to write scientific articles on the six course experiments. Their scientific writings were analyzed based on normativity, objectivity, and logicality. These dimensions of the development of students’ competence in scientific writing during the course were portrayed. This study suggested that student's development in scientific writing can be divided into categories, demonstrating the importance and implications of teaching “learn to write” in science.
