In this paper, we describe student understanding of the "force concept" (basic concepts of Newtonian mechanics) by representing it as a vector-valued quantity, which we refer to as the "score-state vector," in a (30-dimensional) Force Concept Inventory (FCI) score space. We use a large ensemble of FCI results collected…

Cognitive diagnostic assessment based on Bayesian networks (BN) is developed in this paper to evaluate student understanding of the physical concept of buoyancy. we propose a three-order granular-hierarchy BN model which accounts for both fine-grained attributes and high-level proficiencies. Conditional independence in the BN structure is tested…

The aim of this study is to examine the ability of pre-service mathematics teachers to detect errors made in solving questions about matrices. The study particularly focused on revealing the internalization of the teachings such as the meanings and relational dimensions of concepts and operations about matrix. The study was conducted with 26…

In Brazil we have identified a predilection of the authors of Mathematical History books for the discussion of the fundamentals of Differential and Integral Calculus. On the other hand, when we consider the teaching of Mathematics in the school context, it is essential to know the teaching of the historical and dynamic evolution of the concepts,…

Transnational education seeks equivalence in standards and/or relevance of outcomes through the transfer of Western theories, concepts and methods. Utilising a critique-interpretative approach, Jing Qi argues that equivalence/relevance-oriented approaches to transnational education assume the legitimacy of the global knowledge hierarchy.…

As teachers organize classroom schedules to meet curricular demands and time constraints, they strive to seek ways to motivate and sustain student engagement in quality vocabulary instruction, enjoyable learning experiences, and interesting informational books. This article addresses these concerns and describes a vocabulary acquisition strategy…

Purpose: The purpose of this paper is to examine how students' participation in an integrated school food program was related to the development of components of food and health-related action competence (F & HRAC). These components were understood to be the knowledge, insight, motivation, ownership and social skills that made students able to…

Like many colleges across the United States, Pipe Lake Community College (PLCC), (a pseudonym) has experienced a dramatic increase in enrollment of Latina/o students and is considered an emerging Hispanic Serving Institution (HSI). Other than Santiago & Andrade's (2010) survey, little research has been conducted on emerging HSIs. Also, little…

The Knowledge Society Network (KSN) "takes advantage of new knowledge media to maximize and democratize society's knowledge-creating capacity" (www.ikit.org/KSN). This article synthesizes the principles and designs of this network which were initiated over 15 years ago, and presents an exploratory study of interactions in the KSN over…

A fundamental goal of educational research is identifying students' current stage of skill mastery (complete/partial/none). In recent years a number of cognitive diagnosis models have become a popular means of estimating student skill knowledge. However, these models become difficult to estimate as the number of students, items, and skills grows.…

In the School of Education at the University of Adelaide, the use of oral evidence is increasingly common as students engage with reflective practices now dominant in teacher-education programs. These experiences offer both a dynamic perspective and a challenge to academic assessors and raise three questions, each of which are addressed in this…

Developed a structural analysis of 3 spatial diagrams (matrices, networks, and hierarchies) that specifies 10 properties on which these diagrammatic representations are hypothesized to differ. Coded verbal protocols of 23 college students about these representations. Results suggest that the organization of students knowledge is consistent with…

In an effort to increase the quality and quantity of service-learning assessment, this article provides a brief rationale for engaging in service-learning assessment and reviews a selection of available tools for doing so. The paper includes a matrix that lists cognitive outcomes, including critical thinking and problem solving, and the…

Results of cognitive diagnoses were validated using the rule-space model, and the usefulness of cognitive diagnosis for instruction was demonstrated. Through preliminary studies, 33 stages of knowledge were defined as cognitive diagnoses to be applied to results from a test of knowledge about fractions of seventh and eighth graders (initial test…

Most of the literature on student retention focuses on what students do "wrong" that leads to departure from college, but there is much to be learned from studying student success in higher education. This article presents a study designed to uncover the strategies that successful minority students employ to overcome barriers to academic…
