This study addresses the following research question: How does telementoring urban high school students by English teacher candidates develop candidates' cultural competence and impact mentees' cultural identity development? Mentee-mentor exchanges were analyzed to uncover how mentees used writing to develop cultural identity, how…

A novel didactic sequence is proposed for the teaching of chemical equilibrium. This teaching sequence takes into account the historical and epistemological evolution of the concept, the alternative conceptions and learning difficulties highlighted by teaching science and research in education, and the need to focus on both the students'…

This article address the falsehoods regarding No Child Left Behind and Race to the Top legislation, the educational reformers' stance that schools are failing, the privatization movement in education, and the issues of technology in the schools. The importance of poverty is emphasized, although policymakers ignore it and advocate school…

Reaction kinetics is an axiomatic topic in chemistry that is often addressed as early as the high school course and serves as the foundation for more sophisticated conversations in college-level organic, physical, and biological chemistry courses. Despite the fundamental nature of reaction kinetics, students can struggle with transforming their…

We describe how complex concepts in macroscopic chemistry, namely, thermodynamics and kinetics, can be taught at considerable depth both at the first-year undergraduate as well as upper levels. We begin with a careful treatment of PV diagrams, and by pictorially integrating the appropriate area in a PV diagram, we introduce work. This starting…

Gibbs energy profiles provide students with a visual representation of the energy changes that occur during enzyme catalysis, making such profiles useful as teaching and learning tools. Traditional kinetic topics, such as the effect of pH on enzyme activity, are often not discussed in terms of Gibbs energy profiles. Herein, the symbolism of Gibbs…

The heterogeneous equilibrium of the solubility of calcium hydroxide in water is used to predict both its solubility product from solubility and solubility values from solubility product when inert salts, in any concentration, are present. Accepting the necessity of including activity coefficients to treat the saturated solution of calcium…

We propose an articulated computational experiment in which both quantum mechanics (QM) and molecular mechanics (MM) methods are employed to investigate environment effects on the free energy surface for the backbone dihedral angles rotation of the small dipeptide N-Acetyl-N'-methyl-L-alanylamide. This computation exercise is appropriate for an…

Background: Attention-deficit/hyperactivity disorder (ADHD) and childhood-onset psychosis (COP) are chronic, heterogeneous disorders with symptoms that frequently co-occur, but the etiology of their comorbidity is unknown. Studies of each disorder indicate that both ADHD and COP are associated with a range of neuropsychological weaknesses, but few…

Background: Attention problems are among the most prevalent neurobehavioral morbidities affecting very preterm (VPT) born children. The first study aim was to document rates of persistent attention/hyperactivity problems from ages 4 to 9 years in a regional cohort of VPT born children. The second aim was to examine the extent to which persistent…

Effective use of multimedia (MM) in instructional design is critical for student learning, especially for large lecture introductory courses. This study used a mixed-method approach to explore the effect of food science supporting course materials that utilized different MM formats, designed with Cognitive Theory of Multimedia Learning (CTML)…

Communicating complex scientific and technical information presents a challenge for food science educators. The most efficient learning occurs when all senses are engaged, one reason that many educators believe that scientific principles are best taught with hands-on laboratory experiences. Today there are many challenges to the continuation of…

Background: Studies conducted on mild intellectual disability (MID) in children are infrequent and the prevalence rates vary widely. This study aimed to estimate the prevalence of MID in children in a French county (Isère), to describe the clinical signs and associated comorbidities, and to specify the aetiologies of this disability. Methods: The…

Background: Person-centred planning has played a key role in the transformation of intellectual disabilities services for more than a decade. The literature has identified clear advantages for service users when service delivery is planned around the individual rather than the user is made to fit into service structures. Researchers however have…

Background: In the Netherlands, as in many other countries, there are indications of an inclusive school policy for children with Down syndrome. However, there is a lack of studies that evaluate to what extent this policy has actually succeeded in supporting the mainstreaming of these students. Method: For the period 1984-2011, the number of…
