Researchers need to know what is an acceptable number for interview work How does one decide the acceptable number of people to interview? Or one might ask what is an acceptable N size for interview work?
Effects Of A Historical Story On Student Understanding Of Nos, Peng Dai
Effects Of A Historical Story On Student Understanding Of Nos, Peng Dai
Research and Creative Activities Poster Day
Science educators have identified that Nature of Science (NOS) is essential to improve students’ science literacy. Numerous empirical studies suggest that incorporating the history of science (HOS) into class by means of an explicit reflective approach is one way to promote students’ NOS conceptions. In view of these findings, we developed a unit using an interrupted story technique to depict the discovery of the structure of DNA featuring Rosalind Franklin’s neglected role to help students learn both science content and NOS. Our study design compares an experimental group (story used) with a control group (no story used). The SUSSI (a …

Elementary/Middle School Pre-Service Teachers’ Understanding Of Variability And The Use Of Dynamical Statistical Software, Yaomingxin Lu
Research and Creative Activities Poster Day
A primary purpose of the study was to examine the effects of using dynamical statistical software (DSS) on prospective teachers’ (PSTs) understanding of statistical concepts, especially variability. Data were collected from PSTs enrolled in a probability and statistics course designed for prospective K-8 teachers. After initial analysis of the data using coding and classification schemes, we found the need to develop a more targeted framework to analyze students’ different levels of understanding. The variability framework (Garfield & Ben-Zvi, 2005) and the Structure of Observed Learning Outcomes (SOLO) taxonomy were then used in combination to develop a revised framework in order …
