J. Brown was accountable for study conceptualization. M. Van Brakle was accountable for report preparation.Fifteen years ago, Odom and Barrow (1995; Odom, 1995) produced the Diffusion and Osmosis Diagnostic Test (DODT; offered in Odom [1995] and Odom and Barrow [1995]), created to assess secondary and college MedChemExpress T0901317 Biology students’ understanding of osmosis and diffusion. Odom and Barrow reported that functionality around the DODT by college biology majors was regularly poor, and scores earned by college non iology majors and higher school students had been even reduce (Odom, 1995). Although understanding how the basic processes of diffusion and osmosis operate is essential to comprehending a wide variety of biological functions, the investigation of Odom and Barrow and others has demonstrated that student mastery of osmosis and diffusion is very tough to reach. Inadequate understanding of osmosis and diffusion has been documented amongst high college and college students within the United states of america (e.g., Marek, 1986; Westbrook and Marek, 1991; Marek et al., 1994; Zuckerman, 1998; Christianson and Fisher, 1999) and elsewhere (e.g., Friedler et al., 1987; She, 2004). The DODT includes 12 two-tiered, multiple-choice queries. The initial tier asks “What occurs when . . .” (“What”), and needs students to analyze a situation and/or make a prediction about what will take place within a predicament, given specific circumstances. The second tier asks the explanation (“Why”) for the first-tier response. Item distracters (incorrect responses) had been drawn from 20 prevalent misconceptions held by students, as identified by the DODT authors (Odom, 1995; Odom and Barrow, 1995). Twelve years later, Odom and Barrow (2007) examined responses and levels PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/20045416 of certainty among 58 high school students who responded for the DODT after completing a week of instruction about osmosis and diffusion. Responses among subjects have been remarkably related to those obtained previously. Further, the authors assessed students’ confidence levels and discovered that students displayed high levels of self-confidence that their (incorrect) responses on the DODT were accurate. The extended time frame in between studies (12 yr), the similarities in students’ responses across the years, and also the students’ certainty in regards to the correctness of their (incorrect) responses all illustrate the persistence and tenacity of students’ misconceptions (i.e., option ideas, naive tips) with regards to the processes of osmosis and diffusion.
