A valuable extension of the single-rating regression discontinuity design (RDD) is a multiple-rating RDD (MRRDD). To date, four main methods have been used to estimate average treatment effects at the multiple treatment frontiers of an MRRDD: the "surface" method, the "frontier" method, the "binding-score" method, and…

Students' categorization of physics problems reflects their expertise in problem solving. We conducted a pseudolongitudinal study to investigate the development of students' categorization ability. Over 250 Chinese students from grade 10 to grade 12 were asked to categorize 20 problems of kinematics and mechanics into suitable categories based on…

This qualitative study explored educational leaders' conduct in self-reported critical incidents (n = 50). Incidents were analyzed for participants' orientations to self or others and professional values, and assigned to one of four position types: authority, equity, compliance, or strategy. The typology categorizes participants' ethical actions…

The Angoff standard setting method relies on content experts to review exam items and make judgments about the performance of the minimally proficient examinee. Unfortunately, at times content experts may have gaps in their understanding of specific exam content. These gaps are particularly likely to occur when the content domain is broad and/or…

Artificial Neural Networks (ANNs) have been proposed as a promising approach for the classification of students into different levels of a psychological attribute hierarchy. Unfortunately, because such classifications typically rely upon internally produced item response patterns that have not been externally validated, the instability of ANN…

Special education is losing its identity--its visibility, distinctiveness, budget, and basic functions are all at risk. Special education functions include (a) sorting, categorizing, and labeling students who need it; (b) making the right comparisons; (c) honoring diversity but changing "particular" differences; (d) managing stigma; (e)…

Mixing examples of different categories (interleaving) has been shown to promote inductive learning as compared with presenting examples of the same category together (massing). In three studies, we tested whether the advantage of interleaving is exclusively due to the mixing of examples from different categories or to the temporal gap introduced…

The implementation of local wisdom-based science learning model through reconstruction of indigenous science is hoped to improve student's conservationist character. Through this model, student will be familiarized with science and local wisdom to improve their existing conservationist characters. Characters measured in this study were…

Capitalizing on the findings in our preceding study of a purely theoretical model, this paper aims to empirically examine whether and to what extent public universities' institutional missions have transformed in recent years in the States of California and New York by quantifying a degree of functional diversification of universities. We focus on…

By the start of the 2017-18 school year, states must complete their plans to meet the Every Student Succeeds Act of 2015 (ESSA), which requires all states to rethink their school classification systems in consultation with community members. So far, 16 states and Washington, D.C., have submitted their plans to the U.S. Department of Education,…

A recursive partitioning model approach in the form of classification and regression trees (CART) was used with 2012 PISA data for five countries (Canada, Finland, Germany, Singapore-China, and the Unites States). The objective of the study was to determine demographic and educational variables that differentiated between low SES student that were…

Two articles, Edelsbrunner and, Schneider (2013), and Nokelainen and Silander (2014) comment on Musso, Kyndt, Cascallar, and Dochy (2013). Several relevant issues are raised and some important clarifications are made in response to both commentaries. Predictive systems based on artificial neural networks continue to be the focus of current…

"Diagnostic and Statistical Manual of Mental Disorders, fifth edition" ("DSM-5") promises a refined definition of mental disorder, which is tantamount to acknowledging that prior "DSM" definitions have failed to clarify what mental disorder is and why a person should be considered mentally disordered. Since the…

This study presents a new approach for transforming the latent representation derived from a Latent Semantic Analysis (LSA) space into one where dimensions have nonlatent meanings. These meanings are based on lexical descriptors, which are selected by the LSA user. The authors present three analyses that provide examples of the utility of this…

What are crucial determinants of a country's average educational performance? Using data from the OECD PISA 2012 study on 58 countries, we develop a typology of educational regimes based on marketisation in terms of school autonomy and accountability. Following organisational theories, we expect that school autonomy is an ideal condition for…
