The research shared in this conference paper report illustrates how an iterative process to item development that involves expert review and cognitive lab interviews with students can be used to collect evidence of validity for assessment items. Analysis of students' reasoning was also used to expand a model for identifying conceptions and…

"Learner centered" term points out environments that attention to the learners brings to the educational setting. This term includes teaching practices: effort to uncover what learners think in a specific problem on hand, talking about their misconceptions and, giving them situations to readjust their ideas. In Learner centered…

Purposes: This study uses think-alouds and cognitive interviews to provide validity evidence for an online formative assessment--i-Ready Standards Mastery (iSM) mini-assessments--which involves a heavy use of innovative items. iSM mini-assessments are intended to help teachers determine student understanding of each of the on-grade-level Common…

In this study we set out to investigate the errors made by students in logarithms. A test with 16 items was administered to 89 Secondary three students (Year 9). The errors made by the students were categorized using four categories from a framework by Movshovitz-Hadar, Zaslavsky, and Inbar (1987). It was found that students in the top third were…

In this study we explored to what extent middle school teachers were able to appropriately identify proportional situations when presented with various mathematical structures and if there were relationships between attributes of the teachers and their ability to identify proportional situations. Interestingly, there were no strong relationships…

Going beyond measuring accuracy of teachers' judgments of students? achievements, this paper focuses on how prospective elementary teachers proceed in one-on-one diagnostic mathematics interviews. As part of the project diagnose:pro, prospective elementary teachers (PTs) conduct diagnostic interviews with children in grade one and reflect on…

What are Turkish pre, elementary, middle, and high school students' force ideas? And, how do Turkish students' non-normative force ideas differ or be similar to the well-known force misconceptions reported in the literature? Students have false and persistent beliefs about the physical world and they struggle with challenging misconceptions based…

This study examines why 51 schools declined an invitation to participate in a state-funded educator incentive initiative, the Texas Educator Excellence Grant (TEEG) program. Using data from an ongoing evaluation of the TEEG program conducted by the National Center on Performance Incentives (NCPI) under contract with Texas Education Agency, this…

The results of a study of the meiosis models utilized by individuals at varying levels of expertise while reasoning about the process of meiosis are presented. Based on these results, the issues of sources of misconceptions/difficulties and the construction of a sound understanding of meiosis are discussed. Five individuals from each of three…

The study reported in this paper intended to trace what Chinese children think about life and identify their naive theories. Fifty-eight 5-year-old children in Taiwan from 39 kindergartens were interviewed using a semi-structured instrument. Results indicate that preschool children have preconceptions about the concept of life even before entering…

In most research that investigates factors influencing the success of analogies in instruction, an underlying assumption is that students have little or no knowledge of the target situation. It is interesting to ask what factors influence the success of analogies when students believe they understand the target situation. If this understanding is…

This study analyzed graphical solutions of 344 students in grades 4 through college who were administered a 40-item assessment of basic fraction concepts. Of particular interest were six problems that required students to complete the whole given a fractional part presented in area contexts and set contexts. Results indicated that fourth graders…

The Van Hiele theory asserts that there exist five hierarchical levels of geometric thinking that a successful learner passes through. The purpose of the study described in this paper was to investigate the geometric understanding and misconceptions in students in the fourth through eighth grades who have been identified as gifted. The students…

An understanding of the concepts of atoms and molecules is fundamental to the learning of chemistry. Any misconceptions and alternative conceptions related to these concepts which students harbor will impede much further learning. This paper identifies misconceptions related to the fundamental characteristics of atoms and molecules which Grade 12…

This study was part of a continuing exploration of the naive misconceptions of students in the physical sciences conducted within the context of current literature in alternative frameworks. The sample was selected from among those students registered for a liberal education physical science class at a small private college. The method used was a…
