Cooperative work in education; Ability grouping in education; Mathematics -- Study and teaching
This study reviewed research on the effect of heterogeneous ability grouping in a cooperative learning environment on academic achievement in mathematics. A large number of studies has shown the importance of cooperative learning procedure in...
Urban residential structure has been shown to be differentiated by three main factors: socioeconomic status, family status and ethnic status. Additionally, socioeconomic inequality in urban areas has been shown to increase over time. These...
AMP-dependent kinase (AMPK) is a primary energy sensor that controls energy use and production during metabolic cellular stress, such as hypoxia and nutrient deprivation. AMPK activation results in inhibition of anabolic processes and promotion...
Oxytocin (OT) is a neuropeptide hormone/neurotransmitter that has been receiving increased attention from both neuroscientists and neuropsychologists due to its behavioral effects on the brain and nervous system. At first, it was discovered to be...
The occupation of police officer is a profession with many unique characteristics. Research on police work has shown that officers are continuously exposed to threats, must maintain a constant vigilance against crime, feel as if they must be in...
Cell migration is an essential part of many processes including embryonic development, wound healing, and unwanted processes like metastasis. Further study of cell migration is needed to help understand these processes. A cell model system (F9...
Ahearn et al. (J. Heredity 93:210-213) have previously shown that the rat fuzzy and Charles River "hairless" mutations are defects in the same gene on rat Chromosome 1, and are likely orthologues of mouse frizzy (abbreviated fr) on mouse Chromosome...
The strength and conditioning community has seen a growing number of research studies related to the effects that resistance training might have in enhancing physical performance in athletics. In an effort to determine the optimal program or method...
Mathematics -- Study and teaching (Middle school) -- Connecticut -- Evaluation; Mathematical ability -- Testing
According to Hancock, Mattox, and Queen (2005) few studies have examined the effects of block scheduling at the middle level. Those that have shown success at the middle level have been unable to narrow down which specific aspects of block...
Helping is a phenomenon that has been widely studied in psychology. Two types of helping that can occur within an organization are organizational citizenship behavior, or OCB, and volunteering. OCB is helping that occurs during the course of...
Languages, Modern -- Study and teaching (Elementary) -- United States; Education, Elementary -- Parent participation -- United States
Even though studies have shown numerous cognitive and social benefits from early foreign language education, Foreign Languages in Elementary School (FLES) is still a recurrent topic of debate. The key issues involved with FLES focus on...
For over thirty-five years average mathematics scores of students in the United States have been below the international average, indicating problems with performance when compared with students from other countries. The United States National...
RNA editing is a mechanism which is used to increase the number of possible protein products from a specific gene. The catalytic enzymes for RNA editing are known to be present in a wide variety of organisms, including many different insects. It...
Abstract Organisms employ inducible defenses to prevent predation. This occurs when the organism recognizes an environmental cue that leads to the expression of the defensive trait. In marine systems this cue is often chemical in nature. Several...
The discovery of antibiotics was one of the greatest discoveries of the 21st 20th century (Van Kraaig, 1999 and Livermore, 2004). The current need for new antibiotics to fight bacterial pathogens that have become resistant is growing every day. ...
Educators and policymakers have noted and expressed concern about a lack of academic motivation among adolescent high school students. Research has confirmed that intrinsic motivation does decline as students progress through school (Lepper,...
African American college students -- Race identity; African American college students -- Psychological aspects
Research has shown that African American college students who place an emphasis on their ethnic identity are more likely to experience more positive academic outcomes. Further, African Americans who experience minority status stress are better able...
The mouse frizzy (fr) mutation is a Mendelian recessive trait that affects hair structure and formation in mice. The mutation arose in a mouse of mixed origin at the Jackson Lab (Bar Harbor, ME) in 1951. Frizzy is known to be linked to other genes...
Algebra -- Study and teaching (Secondary); Chemistry -- Study and teaching (Secondary); Mathematics -- Study and teaching (Secondary)
The purpose of this study was to determine if integrating a unit on functions would benefit students. Previous studies have shown that integrating science and mathematics increases students' understanding of certain topics in science. Typically,...
