Misconceptions and persistence: resources for targeting student alternative conceptions in biotechnology

Abstract

Conceptual understanding and reasoning of nonscience major students enrolled in a course on biotechnology were evaluated before and after instruction. The instrument for analysis of student understanding was the Biotechnology Instrument for Knowledge Elicitation (BIKE). The BIKE targets 11 key concepts, as determined by experts in the field. A statistically significant score improvement was observed in each of the 11 concept areas after completion of the course, Biotechnology in Society (N = 117). Student responses to both the pretest and posttest were highly informative and revealed several common misconceptions that could have been overlooked in a closed form testing scenario. These alternative conceptions and recommended clarifications have been presented here. Our goal in documenting and distributing these is to better equip educators in biology and biochemistry to anticipate student preconceptions, design targeted interventions, and improve student conceptual reasoning in topics pertaining to biology and biotechnology. © 2018 International Union of Biochemistry and Molecular Biology, 46(6):602–611, 2018.

Examining Secondary School Students’ Misconceptions About the Human Body: Correlations Between the Methods of Drawing and Open-Ended Questions

“…A number of these concepts differ from conventional scientific views. These incorrect concepts are called naïve ideas (e.g., Pine, Messer, & St. John, 2001), alternative conceptions (e.g., Adadan, Trundle, & Irving, 2010;Prokop, Prokop, & Tunnicliffe, 2008b), misconceptions (e.g., Treagust, 1986;Wandersee, 1986), or both alternative conceptions and misconceptions (Wisch, Farrell, Siegel, & Freyermuth, 2018) (for discussion regarding the use of the term misconception see Leonard, Andrews, & Kalinowski, 2014). They have become one of the possible reasons for student's difficulties in the learning process, because they can interfere with the acquisition of new knowledge (Hadzigeorgiou, 2015;Vosniadou, 2001).…”

Effects of fat-containing feed after ultrasound treatment with zeolite on the metabolism

“…One way to detect these disorders is to intravitally diagnose metabolic disorders with the help of morphological and biochemical E3S Web of Conferences 164, 06020 (2020) TPACEE-2019 https://doi.org/10.1051/e3sconf /202016406020 blood indicators. These studies are particularly important in assessing the effects of new fodder substances [5][6][7].…”

Biotoxicity of heavy metal salts to Bacillus subtilis and their sorption properties

“…For many microorganisms, the effectiveness of biological detoxification of metals through targeted microbial activity depends on factors such as the age of culture, the cell shape, pH, contact time, and initial concentrations of metals in the solution [6]. In this regard, several studies with actively growing cells showed that some microorganisms could effectively remove heavy metal ions from the nutrient environment, especially when the concentration of metals was relatively low [7].…”
