This study examines how two kinds of authentic research experiences related to smoking behavior--genotyping human DNA (wet lab) and using a database to test hypotheses about factors that affect smoking behavior (dry lab)--influence students' perceptions and understanding of scientific research and related science concepts. The study used pre and…

Given the rapid development of modern biotechnology, attention to socioscientific issues in educational contexts is crucially important to support students in becoming responsible citizens. The authors' research focused on the impact of discussing socioscientific issues during biology lessons under 3 different treatments (teacher guided, student…

This study examined the characteristics of virtual and hands-on inquiry environments for the development of blended learning in a popular domain of bio-nanotechnology: the separation of different-sized DNA fragments using gel-electrophoresis, also known as DNA-fingerprinting. Since the latest scientific developments in nano- and micro-scale tools…

Cell-free protein synthesis (CFPS) has emerged as a practical method for producing a broad variety of proteins. In addition, the direct accessibility to the reaction environment makes CFPS particularly suitable as a learning vehicle for fundamental biological concepts. Here, we describe its implementation as a teaching tool for a high school…

Scientists routinely integrate information from various channels to explore topics under study. We designed a 4-wk undergraduate laboratory module that used a multifaceted approach to study a question in molecular genetics. Specifically, students investigated whether "Caenorhabditis elegans" can be a useful model system for studying genes…

In an effort to overcome deficiencies in teaching molecular biology at school, a workshop in an out-of-school laboratory including only authentic experiments was developed. Evaluation of 337 A-level 12th graders followed a quasi-experimental design, with one hands-on group, two non-experimental control groups (at school/in the laboratory), and one…
