For the most part, contemporary logicians discuss previous logicians’ ideas from different civilizations and make comments thereon, thus addressing specialists in logic studies. In many education systems, the science philosophy and logic principles do not play a preliminary role. Today, in many education systems the science of philosophical thinking and logic principles should play a preliminary role for rational inferences. Unfortunately, in education systems there is little formal training about the principles of logic and their extraordinary capacity to sharpen the (...) mind with brain experiments, which leads to the attaining of innovative ideas. This is the case especially in engineering institutions, where the students are fed with various mathematical principles, equations and numerical solution methodologies. Although classically almost everybody states that mathematics is based on logic, logical principles are not thought through systematically in education systems.. In this short paper the main purpose is to mention t the logical principles that should be beneficial to the young generation, regardless of whether the interest is in logical sciences or in basic works to arrive at limitless logical conclusions.

A variety of semiotic resources makes the construction of scientific knowledge possible and meaning-making resources are conveyed by certain semiotic modes. Next, numerous studies have demonstrated the pedagogical importance of gestures in the demonstration of scientific knowledge in the classroom. Drawing on social semiotic systemic functional theory and legitimation code theory, this study explores the types and the role of gestures in the semiotic construction of scientific knowledge in pedagogic semiosis and their pedagogical values for the meaning-making of science content. (...) With this aim, a gesture observation protocol (GOP) is developed to annotate and analyze data. Two science lectures, which are broadcast remotely for middle school students including gifted students, are observed. Systemic Functional Multimodal Discourse Analysis (SF-MDA) method is employed to analyze and evaluate data. Results demonstrated that the deployment of gestures that contributes to the construction of scientific knowledge is low and deployed gestures mostly do not have pedagogical value. It is recommended that teachers should be more conscious and educated about deploying gestures to present scientific knowledge efficiently. (shrink)
