As one of the core skills of the 21st century, computational thinking has received increasing attention from educators and researchers. Although some research has been conducted on computational thinking, few studies examined the impact of learning activities on students' computation thinking skills from the perspective of cognitive development.…

The main purpose of this study was to describe the development and use of a flowchart for preservice chemistry teachers' problem solving on the First Law of Thermodynamics. Twenty-seven undergraduate preservice chemistry teachers attending a Physical Chemistry course participated in this study. The responses of the participants to the set of test…

The results of qualitative and quantitative investigations conducted with individuals who learned algorithms in school are presented in this article. In these investigations, eye-tracking technology was used to follow the process of solving algorithmic problems. The algorithmic problems were presented in two comparable variants: in a pseudocode…

Reaction workup can be a complex problem for those facing novel synthesis of difficult compounds for the first time. Workup problem solving by systematic thinking should be inculcated as mid-graduate-level is reached. A structured approach is proposed, building decision tree flowcharts to analyze challenges, and an exemplar flowchart is presented…

There are different opinions about the meaning of feedforward: some consider it a response to feedback, while others think it consists of suggestions given to a person in order to help them before learning or starting a task. This study analyzed the professor's and university students' actions during a seminar activity with a group of 60 students…

This teaching case discusses the analysis of an electronic voting system. The development of the case was motivated by research into information security and management, but as it includes procedural aspects, organizational structure and personnel, it is a suitable basis for all aspects of systems analysis, planning and design tasks. The material…

A major motorcycle vendor, based in the U.S. Midwest, is the world's largest custom V-Twin motorcycle manufacturer and domestically the second largest motorcycle manufacturer behind Harley-Davidson. This project describes the process used used by a K-State undergraduate distance learning student to design and develop the initial version of a…

The paper reports a study of the knowledge preservice secondary school mathematics teachers [PSSMT] hold of problem solving and the role of a reflective-inquiry approach in creating self-awareness of, and in enhancing, this knowledge. The approach included solving problems, narratives, flow charts and observations. The finding shows that the…
