Advancing scientific literacy: Integrating nature of science and nature of scientific inquiry in teaching Griffith’s and Avery-MacLeod-McCarty experiments

The present study aims to design an instruction that engages nature of science (NOS) and nature of scientific inquiry (NOSI) learning objectives with the teaching and learning of important historical experiments taught around the world and presented in most biology textbooks such as those by Griffith and by Avery, MacLeod, and McCarty. The design process involves decisions about which NOS and NOSI aspects to teach and decisions about how to teach. With respect to the latter decisions, our preference is an explicit/reflective perspective used in an overarching inquiry-based science teaching and history of science instructional context. The proposed course is going to provide high school students meaningful and practical inquiry-based experiences through the use of simulated experiments and would help their teachers (a) illuminate several procedural aspects of the taught experiments (b) internalize the importance of teaching NOS and NOSI aspects (c) acquire an integrative understanding of the process of scientific inquiry and the product of that inquiry, namely scientific knowledge, and (d) portray science less as a body of knowledge and more as a creative process involving human and non-human actors. The potential benefits of our proposed instruction for learners’ scientific literacy are also discussed.

Building search and analytical competences of master’s students for scientific reviewing

Today, scientific reviewing is not the area of strength of Russian researchers. In many ways, it is due to the lack of research competences taught to the graduate students, and, in particular, search and analytical competences that correspond to the active-operational component of the competence. To overcome this shortcoming, the authors have developed and tested an approach to selecting publications for scientific reviewing. The approach comprises five steps: selecting the starting sample, its expansion, truncation, analysis, and final selection. The pedagogical experiment accomplished with the small groups demonstrated significant increase in the level of research competences in the master’s students who took the specialized course Science Communication based on the above approach. The course resulted in increased competences essential for effective search and analysis of scientific information. Further implementation of the method will improve the educational environment for building research competences in graduate students.

Teaching practice aimed at promoting student engagement with metarules of defining

By viewing students’ learning to define as learning about meta-discursive rules about defining and how to engage with them in their activity of defining, we investigated teaching practices that aim to promote such learning by analyzing a teaching experiment in which Calculus II students reinvented a formal definition of a limit. The teaching practices we identified addressed how students view defining tasks by providing a method to check whether their narratives satisfied the metarules that they aimed to follow and also provided guidance about how to revise their definitions to satisfy those metarules. Our results provide an example for the teaching practice that promotes student learning about and engagement with new meta-discursive rules that existing literature called for in general, especially in their reinvention of a formal definition of a mathematical object.
