This article reviews the background of the foreign language bilingualism in Colombia, as well as the Colombian bilingualism plans and the policy launched between 2004 and 2016. Then, these plans and policy are analyzed taking into account the most common criticisms from the academic community. In this sense, aspects such as the lack of continuity,…

Sexual violence on college campuses is a pervasive problem with the potential for extensive physical and psychological health consequences. Institutions have begun implementing prevention programs; however, more research is needed to understand whether these programs are effective. Bystander intervention programs have increased in popularity…

The relationship between enactment of Common Core State Standards-Mathematics (CCSSM), student misconceptions, student achievement and teacher variables was investigated. After providing professional development on CCSSM enactment, observations were conducted to determine the degree of enactment of CCSSM content and Standards for Mathematical…

The aim of this qualitative study is to embed ICT in the teaching and learning of A-level vectors. Initially, students' learning difficulties and misconceptions in A-level vectors were diagnosed. Then, based on the difficulties identified, concepts in vectors together with interactive tools were developed and integrated in a webpage to enhance the…

Organic chemistry is an essential subject for many undergraduate students completing degrees in science, engineering, and pre-professional programs. However, students often struggle with the concepts and skills required to successfully solve organic chemistry exercises. Since alkyl halides are traditionally the first functional group that is…

It was 126 years ago that Down first described savant syndrome as a specific condition and 70 years ago that Kanner first described Early Infantile Autism. While as many as one in ten autistic persons have savant abilities, such special skills occur in other CNS conditions as well such that approximately 50% of cases of savant syndrome have autism…

The purpose of this study was to deconstruct the relationship between visual static models and students' written solutions to fraction problems using a large sample of students' solutions. Participants in the study included 162 third-grade and 209 fourth-grade students from 17 different classrooms. Students' written responses to open-ended tasks…

This work uses microgenetic study of classroom learning to illuminate (1) the role of pre-instructional student knowledge in the construction of normative scientific knowledge, and (2) the learning mechanisms that drive change. Three enactments of an instructional sequence designed to lead to a scientific understanding of thermal equilibration are…

The "mole" is a fundamental concept in quantitative chemistry, yet research has shown that the mole is one of the most perplexing concepts in the teaching and learning of chemistry. This paper provides a survey of the relevant literature, identifies the necessary components of a sound understanding of the mole concept, and unpacks and…

High education expectations--and the tools to ensure that they are being met--empower educators, students, parents, and policymakers to support student learning and make the best decisions to improve education. Most states have voluntarily adopted the Common Core State Standards to serve as their education expectations. To consistently and…

To understand the mathematical concept of function, students must understand certain subconcepts, such as domain and range. Many researchers have studied students' understanding of functions, but no study has focused on how students come to understand the domain and range for the graphs of functions. In this study, we identified four common…

This paper illustrates the use of simulation-based performance assessment (PA) methodology in a recent study of eighth-grade students' understanding of physical science concepts. A set of four simulation-based PA tasks were iteratively developed to assess student understanding of an array of physical science concepts, including net force,…

This study describes primary school students' knowledge about rainfall, clouds and rainbow formation together with teachers' predictions about students' performance. In our study, primary school students' (N = 177) knowledge about rainfall and rainbow formation was examined using structured interviews with open-ended questions. Primary school…

The present study investigated knowledge, misconceptions, and lack of information about dyslexia among pre-service (PST) and in-service (IST) Spanish-speaking teachers in Spain and Peru. Two hundred and forty-six pre-service teachers and 267 in-service teachers completed the Knowledge and Beliefs about Developmental Dyslexia Scale (KBDDS).…

Few studies investigate what members of the general population know about individuals with autism. Only one study has previously investigated how beliefs about autism differ from those about other psychiatric disorders. This study surveyed a convenience sample of the general adult population, within the Northern Region of Denmark, about their…
