Several studies support that stored memories undergo a new period of consolidation after retrieval. It is not known whether this process, termed reconsolidation, requires the same transcriptional mechanisms involved in consolidation. Increasing evidence supports the participation of the transcription factor NF-[Kappa]B in memory. This was…

This paper proposes a methodology to calculate both the difficulty of the basic problems and the difficulty of solving a problem. The method to calculate the difficulty of problem is according to the process of constructing a problem, including Concept Selection, Unknown Designation, and Proposition Construction. Some necessary measures observed…

Diagrams are considered to be invaluable teaching and learning tools in biochemistry, because they help learners build mental models of phenomena, which allows for comprehension and integration of scientific concepts. Sometimes, however, students experience difficulties with the interpretation of diagrams, which may have a negative effect on their…

The purpose of this study was to explore the use of a cognitive computer tool by undergraduate calculus students as they worked cooperatively on mathematical tasks. Specific attention was given to levels of cognitive demand in which the students were engaged as they completed in-class labs with the assistance of MathCAD. Participants were assigned…

Multidimensional item response theory (IRT) models have been proposed for better understanding the dimensional structure of data or to define diagnostic profiles of student learning. A compensatory multidimensional two-parameter partial credit model (M-2PPC) for constructed-response items is presented that is a generalization of those proposed to…

This is the 31st Annual Report to Congress on the Implementation of the "Individuals with Disabilities Education Act," 2009. Section 664(d) of the "Individuals with Disabilities Education Act" ("IDEA") (P.L. 108-446), as reauthorized in 2004, requires that the Department of Education report annually on the progress…

The 12th iteration of the International Conference on Educational Data Mining (EDM 2019) is organized under the auspices of the International Educational Data Mining Society in Montreal, Canada. The theme of this year's conference is EDM in Open-Ended Domains. As EDM has matured it has increasingly been applied to open-ended and ill-defined tasks…

Web site usability concerns anyone with a Web site to maintain. Libraries, however, are often the biggest offenders in terms of usability. In our efforts to provide users with everything they need for research, we often overwhelm them with sites that are confusing in structure, difficult to navigate, and weighed down with jargon. Dowling College…

This study examined how 30 general education and 30 special education elementary grade teachers rated the importance of social skills to classroom success and positive relationships of children with learning disabilities, and also considered how teachers determine ratings of difficulty of acquisition of social skills by children with learning…

This Monte Carlo study examined the effect of complex sampling of items on the measurement of differential item functioning (DIF) using the Mantel-Haenszel procedure. Data were generated using a three-parameter logistic item response theory model according to the balanced incomplete block (BIB) design used in the National Assessment of Educational…

This paper deals with the problems that arise in performance assessment from the granularity that results from having a small number of tasks or prompts and raters of responses to these tasks or prompts. Two problems are discussed in detail: (1) achieving a satisfactory degree of reliability; and (2) equating or adjusting for differences of…

Of the four language skills, reading is probably tested most often, and it may seem to be the easiest to test. However, testing reading proficiency has its difficulties, and the test constructor must be aware of several issues. Reading involves a number of skills, and the number and complexity of these must be recognized. Choosing the text to test…

Computerized adaptive (CA) testing uses an algorithm to match examinee ability to item difficulty, while self-adapted (SA) testing allows the examinee to choose the difficulty of his or her items. Research comparing SA and CA testing has shown that examinees experience lower anxiety and improved performance with SA testing. All previous research…

An examination of the content and level of mastery required of students taking statewide mathematics achievement tests was conducted to provide clues about the kind and level of mathematics valued in the United States. Proposals for voluntary national tests also contributed to the rationale for the study. In particular, this study: (1) examined…

A study assessed the cognitive level of academic challenges incorporated into courses offered in the College of Agricultural Sciences at the Pennsylvania State University. Eleven faculty members from nine departments provided copies of all academic challenges used in their courses. They were categorized by type: activities, problem sets, written…
