Countries that best prepare math teachers share similarities: Several key conditions generally lacking in US

Countries that best prepare math teachers meet several key conditions generally lacking in the United States, according to the first international study of what teacher preparation programs are able to accomplish.

The IEA study, led by Michigan State University, suggests that in countries such as Taiwan and Singapore, future math teachers are better prepared because the students get rigorous math instruction in high school; university teacher-preparation programs are highly selective and demanding; and the teaching profession is attractive, with excellent pay, benefits and job security.

The Teacher Education and Development Study, or TEDS-M, provides strong evidence of the benefits of teacher-preparation programs at colleges and universities. The six-year study was funded by the National Science Foundation, which provided $4.2 million, as well as the International Association for the Evaluation of Educational Achievement, or IEA, and the participating countries.

"Some critics of teacher education believe you can bypass colleges of education and prepare teachers in an easier, faster way, but our study doesn't support that," said Maria Teresa Tatto, international study director and MSU associate professor of education.

"In Taiwan, for example, nobody graduates without the demonstrated ability to teach mathematics," she said. "Here in the United States, far too many of our graduates lack the knowledge of mathematics and how to teach it, which they will need as they begin to teach."

The researchers collected data from representative national samples that included about 500 higher education institutions in 17 countries that prepare primary and secondary school teachers. Some 22,000 future teachers were surveyed and tested, and 5,000 instructors were also surveyed. The full data from the report will be published soon on the IEA's website.

The researchers looked at how well the teaching students knew math and how much they knew about how to teach it.

The differences between top and bottom scoring countries were very large, Tatto said. Taiwan and Singapore did far and away the best in preparing math teachers. Russia also scored highly. Poland, Switzerland and Germany did well partly because they rely more on specialist teachers in lower grades.

The United States generally finished below this group but above other countries that scored way below the international average, Tatto said.

John Schwille, a researcher on the project and MSU education professor, said the results offer grounds for optimism about what can be done to improve teacher preparation and overcome a climate of skepticism.

The study, he added, is in part a response to the belief among many in the United States that teachers are "born and not made, so why are we wasting our time on university programs?" Critics argue that university-based teaching programs are costly and take longer than the alternative of just hiring talented liberal arts graduates and putting them more directly in classrooms.

But this argument doesn't hold up, Schwille said.

"There are some 'born' teachers, sure, but not enough to fill the classrooms," he said. "So you're going to have to prepare them. And the countries that do it best rely on university-based teacher education programs."

The international research team also included MSU professors Sharon Senk and Mark Reckase; MSU alumnus Michael Rodriguez; Kiril Bankov from the University of Sofia in Bulgaria; Lawrence Ingvarson, Glenn Rowley and Ray Peck from the Australian Council for Educational Research; a group of survey and sampling specialists from IEA; and mathematicians and mathematics educators worldwide who served as advisers.

 

Math teachers demonstrate a bias toward white male students, study finds

— While theories about race, gender, and math ability among high school students have long been debated, a recent study found that math teachers are, in fact, unjustifiably biased toward their white male students. This study was published in a new article released in the April 2012 issue of Gender & Society (GENDSOC), the official journal of the Sociologists for Women in Society, published by SAGE.

"This speaks to the presence of a perhaps subtle yet omnipresent stereotype in high school classrooms: Math, comparatively speaking, is just easier for white males than it is for white females," wrote the authors.

Researchers Catherine Riegle-Crumb and Melissa Humphries analyzed data collected by the National Center of Education Statistics (NCES) that consisted of a nationally representative group of about 15,000 students. Their data also included teacher surveys in which math teachers were asked to offer their personal assessment of individual students, indicating whether they felt that the course was too easy for the student, the appropriate level, or too difficult. The researchers compared these assessments with other data about the students such as their math GPA and their score on a standardized math test in order to determine if the teachers' perceptions of their students' abilities matched up with the students' actual scores.

After analyzing this data, the researchers found disparities between teachers' favorable perceptions of the abilities of their white male students and these students' scores. Conversely, white female students were perceived by teachers to be doing more poorly in their math classes than they actually were.

The researchers did not, however, find the same disparities between white students and minority students. In fact, they found that math teachers actually favored black female students, claiming that these students were more successful in their math classes than they actually were.

The authors wrote, "Once we take into account that, on average, Black and Hispanic male and female students have lower grades and test scores than white males, teachers do not rate the math ability of minority students less favorably than students belonging to the traditionally advantaged category of white males."

Riegle-Crumb and Humphries offered some explanations for their findings. For example, since few black females were enrolled in high-level math courses, teachers may have viewed the black female students in their advanced courses as overcoming more to be successful in mathematics, thus illustrating more perseverance and academic potential. Additionally, they explained that teachers may be more sensitive to their own tendencies towards racial bias than gender bias as gender bias may be so socially ingrained that it is harder to notice and therefore harder to resist.

The authors wrote, "The occurrence of bias in high school classrooms indicates that cultural expectations likely function to shape interactions and re-create inequality throughout the math pipeline that leads to high-status occupations in related fields of science and technology."

Plugged into learning: Computers help students advance

 Technology has grown by leaps and bounds, yet are computers helping students progress in their learning? Absolutely, says a 40-year retrospective on the impact of technology in classrooms.

Published in the journal Review of Educational Research, the findings gathered by Concordia University researchers suggest that technology delivers content and supports student achievement.

Expanded from a doctoral thesis by Rana Tamim, the study's first author, the research brought together data from 60,000 elementary school, high school, and post-secondary students. It compared achievement in classrooms that used computer technology versus those that used little or none.

In those classrooms where computers were used to support teaching, the technology was found to have a small to moderate positive impact on both learning and attitude. "We deduce that the impact would be even greater if observed over a student's entire educational experience," says co-author Richard Schmid, chair of Concordia's Department of Education and a member of the university's Centre for the Study of Learning and Performance.

The research team found technology works best when students are encouraged to think critically and communicate effectively. "A standard PowerPoint presentation will most likely not enhance the learning experience beyond providing content or enhancing teacher-directed lectures or class discussions," says Schmid.

The team now plans to evaluate what technologies work best for what subjects. "Educational technology is not a homogenous intervention, but provides a broad variety of tools and strategies for learning," says Schmid, adding there are few resources available to keep teachers abreast of newer technologies and their potential.

"Teachers across Quebec are not particularly familiar with the use of technology to promote learning," he stresses. "The problem is compounded by the fact that children are increasingly more adept with computers. One of the mandates of Centre for the Study of Learning and Performance at Concordia is to support teachers and provide the tools to facilitate the integration of technology into their classrooms."

Adolescents from unstable families lose ground in rigorous high schools

— Research continues to support a connection between instability in the home and school performance in adolescents, but a new study in the January issue of Sociology of Education takes the research a step further by exploring how the relationship between family structure change and adolescent academic careers is also affected by the kinds of schools they attend.

According to study co-author Shannon Cavanagh, a professor in The University of Texas at Austin's Department of Sociology, schools vary considerably in terms of socio-demographic composition and "academic press," measured by whether the school is defined by academic, achievement-oriented values, goals, and norms and by specific standards of achievement.

"For these reasons, we were curious about whether the family instability effect on course-taking behaviors might be different (stronger or weaker) in different kinds of schools," she said.

What Cavanagh and study co-author Paula Fomby, an assistant professor in the University of Colorado Denver's Department of Sociology, found supports what is called the "mismatch hypothesis" — a theory that suggests that students who have experienced repeated changes in their family structure status will be less successful academically when attending schools with higher levels of academic press.

Cavanagh and Fomby used data from a nationally representative, longitudinal study of students who were in high school in the mid-1990s. They chose to focus on math course-taking patterns, since math is among the strongest predictors of college matriculation. Academic status in mathematics at the end of high school not only represents interest and ability in the subject, but, more generally, it captures a clearer picture of a student's cumulative high school career.

Because the data from the chosen study included information on students' school records and their families as well as multiple reporter accounts of the characteristics of their schools, Cavanagh and Fomby were able to relate a specific characteristic of each student — their family structure history — with school characteristics such as the level of academic press and the percentage of students who were from single-parent homes.

"This interaction allowed us to determine the context in which a student's own family history had the greatest impact on their course-taking patterns," Cavanagh said.

"While students in a high-academic press school, regardless of family instability histories, are higher achieving in terms of course-taking compared to their peers overall, students who have experienced repeated family structure changes lose some part of their advantage," Cavanagh said. As such, Cavanagh and Fomby frame their results in terms of "lost gains."

Unfortunately, the results of the study complicate the work of policymakers and educators who have historically sought to mitigate social disadvantages through access to opportunities and resources found in higher-performing schools. While acknowledging that there are people specifically trained to convert academic findings into policy, Cavanagh does highlight the need for teachers and school leaders to clarify what she calls the "opaque process of college preparation" and to help parents ask the right questions about their student's college preparation.

"[School administrations] can remove some of this opacity with broad information campaigns about the expectations that colleges and employers have for student learning," Cavanagh suggested. "Local business and community leaders who join schools in an effort to prepare college-ready high school graduates may also be effective in reaching parents and adolescents."

What are friends for? Negating negativity

 — 'Stand by me' is a common refrain when it comes to friendship but new research from Concordia University proves that the concept goes beyond pop music: keeping friends close has real physiological and psychological benefits.

The presence of a best friend directly affects children going through negative experiences, as reported in the recent Concordia-based study, which was published in the journal Developmental Psychology and conducted with the collaboration of researchers at the Cincinnati Children's Hospital Medical Center and the University of Nebraska at Omaha. Feelings of self-worth and levels of cortisol, a hormone produced naturally by the adrenal gland in direct response to stress, are largely dependent on the social context of a negative experience.

"Having a best friend present during an unpleasant event has an immediate impact on a child's body and mind," says co-author William M. Bukowski, a psychology professor and director of the Concordia Centre for Research in Human Development. "If a child is alone when he or she gets in trouble with a teacher or has an argument with a classmate, we see a measurable increase in cortisol levels and decrease in feelings of self-worth."

A total of 55 boys and 48 girls from grades 5 and 6 in local Montreal schools took part in the study. Participants kept journals on their feelings and experiences over the course of four days and submitted to regular saliva tests that monitored cortisol levels.

Although previous studies have shown that friendships can protect against later adjustment difficulties, this study is the first to definitively demonstrate that the presence of a friend results in an immediate benefit for the child undergoing a negative experience.

These results have far-reaching implications. "Our physiological and psychological reactions to negative experiences as children impacts us later in life," explains Bukowski. "Excessive secretion of cortisol can lead to significant physiological changes, including immune suppression and decreased bone formation. Increased stress can really slow down a child's development." When it comes to feelings of self-worth, Bukowski goes on, "what we learn about ourselves as children is how we form our adult identities. If we build up feelings of low self-worth during childhood, this will translate directly into how we see ourselves as adults."

The study builds on previous research at Concordia that has shown multiple friendships inoculate against negative outcomes such as bullying, exclusion and other kinds of aggression.

Lifelong payoff for attentive kindergarten kids

Attentiveness in kindergarten accurately predicts the development of "work-oriented" skills in school children, according to a new study published by Dr. Linda Pagani, a professor and researcher at the University of Montreal and CHU Sainte-Justine. Elementary school teachers made observations of attention skills in over a thousand kindergarten children. Then, from grades 1 to 6, homeroom teachers rated how well the children worked both autonomously and with fellow classmates, their levels of self-control and self-confidence, and their ability to follow directions and rules.

"For children, the classroom is the workplace, and this is why productive, task-oriented behaviour in that context later translates to the labour market," Pagani said. "Children who are more likely to work autonomously and harmoniously with fellow classmates, with good self-control and confidence, and who follow directions and rules are more likely to continue such productive behaviors into the adult workplace. In child psychology, we call this the developmental evolution of work-oriented skills, from childhood to adulthood."

All the children attended kindergarten in the poorest neighborhoods of Montreal, and their teachers used a carefully constructed observational scale to score them on their attentiveness skills. Over time, the researchers identified the evolution of three groups of children: those with high, medium, and low classroom engagement. All analyses were reviewed to take into account various explanations for the link that was observed between kindergarten attention and classroom engagement.

"Teachers spend many hours per day in school-related activities and can therefore reliably report on them," Pagani explained. The researchers found that boys, aggressive children, and children with lower cognitive skills in kindergarten were much more likely to belong to the low trajectory.

"There are important life risks associated with attention deficits in childhood, which include high-school dropout, unemployment, and problematic substance abuse. Pagani said. "Our findings make a compelling case for early identification and treatment of attention problems, as early remediation represents the least costly form of intervention. Universal approaches to bolstering attention skills in kindergarten might translate into stable and productive pathways toward learning." The researchers noted that the next step would be to undertake further study into how specifically the classroom environment influences children's attention spans.

The study was published online by the Journal of Abnormal Child Psychology, (the official publication of the International Society for Research in Child and Adolescent Psychopathology), on January 13, 2011, and received funding from the Social Science and Humanities Research Council of Canada and the Fonds de recherche sur la société et la culture. Dr. Linda Pagani is affiliated with the University of Montreal's School of Psycho-Education and the Centre hospitalier universitaire Sainte-Justine Research Centre. The University of Montreal is officially known as Université de Montréal.

Why the middle finger has such a slow connection

Each part of the body has its own nerve cell area in the brain -we therefore have a map of our bodies in our heads. The functional significance of these maps is largely unclear. What effects they can have is now shown by RUB neuroscientists through reaction time measurements combined with learning experiments and "computational modelling." They have been able to demonstrate that inhibitory influences of neighbouring "finger nerve cells" affect the reaction time of a finger. The fingers on the outside — i.e. the thumb and little finger — therefore react faster than the middle finger, which is exposed to the "cross fire" of two neighbours on each side. Through targeted learning, this speed handicap can be compensated.

The working group led by PD Dr. Hubert Dinse (Neural Plasticity Lab at the Institute for Neuroral Computation) report in the current issue of PNAS.

Thumb and little finger are the quickest

The researchers set subjects a simple task to measure the speed of decision: they showed them an image on a monitor that represented all ten fingers. If one of the fingers was marked, the subjects were to press a corresponding key as quickly as possible with that finger. The thumb and little finger were the fastest. The middle finger brought up the rear. "You might think that this has anatomical reasons or depends on the exercise" said Dr Dinse, "but we were able to rule that out through further tests. In principle, each finger is able to react equally quickly. Only in the selection task, the middle finger is at a distinct disadvantage."

Computer simulation depicts brain maps

To explain their observations, the researchers used computer simulations based on a so-called mean-field model. It is especially suited for modelling large neuronal networks in the brain. For these simulations, each individual finger is represented by a group of nerve cells, which are arranged in the form of a topographic map of the fingers based on the actual conditions in the somatosensory cortex of the brain. "Adjacent fingers are adjacent in the brain too, and thus also in the simulation," explained Dr. Dinse. The communication of the nerve cells amongst themselves is organised so that the nerve cells interact through mutual excitation and inhibition.

Inhibitory influences from both sides slow down the middle finger

The computer simulations showed that the longer reaction time of the middle finger in a multiple choice task is a consequence of the fact that the middle finger is within the inhibition range of the two adjacent fingers. The thumb and little finger on the other hand only receive an inhibitory effect of comparable strength from one adjacent finger each. "In other words, the high level of inhibition received by the nerve cells of the middle fingers mean that it takes longer for the excitement to build up — they therefore react more slowly" said Dr. Dinse.

Targeted reduction of the inhibition through learning

From the results of the computer simulation it can be concluded that weaker inhibition from the neighbouring fingers would shorten the reaction time of the middle finger. This would require a so-termed plastic change in the brain — a specialty of the Neural Plasticity Lab, which has been studying the development of learning protocols that induce such changes for years. One such protocol is the repeated stimulation of certain nerve cell groups, which the laboratory has already used in many experiments. "If, for example, you stimulate one finger electrically or by means of vibration for two to three hours, then its representation in the brain changes" explained Dr. Dinse. The result is an improvement in the sense of touch and a measurable reduction of the inhibitory processes in this brain area. This also results in the enlargement of the representation of the finger stimulated.

Second experiment confirms the prediction

The Bochum researchers then conducted a second experiment in which the middle finger of the right hand was subjected to such stimulation. The result was a significant shortening of the reaction time of this finger in the selection task. "This finding confirms our prediction" Dr. Dinse summed up. Thus, for the first time, Bochum's researchers have established a direct link between the so-called lateral inhibitory processes and decision making processes. They have shown that learning proces

High-quality child care found good for children — and their mothers

NewsPsychology (Feb. 8, 2012) — High-quality early child care isn’t important just for children, but for their mothers, too. That’s the conclusion of a new study by researchers at the University of Texas at Austin; the study appears in the journal Child Development. The study analyzed data from more than 1,300 children in the longitudinal Study of Early Child Care and Youth Development, which was sponsored by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD).

As part of the study, children’s care settings were evaluated at multiple points when the children were 1 to 54 months old, and moms were interviewed at regular intervals; in this way, researchers created histories of child care location and quality from birth.

The study found that mothers whose children spent their early years in high-quality nonparental care, starting from birth and in either center-based or home-based settings, were more likely than other moms to be involved in their children’s schools later, regardless of the moms’ socioeconomic status. Other moms were those whose children weren’t in child care or were in low-quality child care. School involvement included being in regular contact with teachers or being involved with the school community after their children entered kindergarten — for example, attending open house events at school or visiting the homes of the parents of their children’s classmates.

Moreover, the effects of this early child care were cumulative. The quality of the child care the year before children started school didn’t matter as much as the history of the quality of care throughout the children’s early life. And the quality of children’s early care was more important than the type or setting of the care.

“These findings tie into two important components,” according to Robert Crosnoe, professor of sociology in the Population Research Center at the University of Texas at Austin, who led the study. “First, high-quality child care promotes school readiness, a phenomenon that motivates programs like Head Start and universal prekindergarten. And second, children make a smoother transition to school when families and schools are strongly connected, as reflected in the goals of No Child Left Behind.”

Crosnoe says the study has implications for policy and practice: “Linking multiple settings of early childhood — home, child care, and school — early in children’s lives helps support children’s school readiness and early academic progress,” he notes.

The study was supported by NICHD and the Foundation for Child Development.

To perform with less effort, practice beyond perfection

Whether you are an athlete, a musician or a stroke patient learning to walk again, practice can make perfect, but more practice may make you more efficient, according to a surprising new University of Colorado Boulder study.

The study, led by CU-Boulder Assistant Professor Alaa Ahmed, looked at how test subjects learned particular arm-reaching movements using a robotic arm. The results showed that even after a reaching task had been learned and the corresponding decrease in muscle activity had reached a stable state, the overall energy costs to the test subjects continued to decrease. By the end of the task, the net metabolic cost as measured by oxygen consumption and carbon dioxide exhalation had decreased by about 20 percent, she said.

"The message from this study is that in order to perform with less effort, keep on practicing, even after it seems as if the task has been learned," said Ahmed of CU-Boulder's integrative physiology department. "We have shown there is an advantage to continued practice beyond any visible changes in performance."

A paper on the subject was published in the Feb. 8 issue of the Journal of Neuroscience. Co-authors on the study include postdoctoral fellow Helen J. Huang and Professor Rodger Kram, both in CU-Boulder's integrative physiology department. The study was funded by the National Institutes of Health.

The study involved 15 right-handed test subjects who used a handle on a robotic arm, similar to a joystick, to control a cursor on a computer screen. The tasks involved starting from a set position to reach for a target on the screen and involved both inward and outward arm movements, Ahmed said.

As part of the study, test subjects had to exert more energy in some reaching movements when the robotic arm created a force field, making subjects "push back" as they steered the cursor toward the target. With repeated practice of moving the robotic arm against the force fields, the subjects learned the task by not only cutting down on errors, but effort as well, according to Ahmed.

The test subjects first performed a series of 200 reaching trials with no force field to push against, then two sets of 250 trials each when pushing back against the force field. The experiment ended with another 200 trials with no force field, said Ahmed. A metronome was used to signal the test subjects to move the robotic arm every two seconds toward the target during the trials.

Each of the test subjects wore a nose clip and breathed through a mouthpiece to chart the rates of oxygen consumption and carbon dioxide production, a measure of metabolism. The research team also collected surface electromyographic data by placing electrodes on the six upper limb muscles used during reaching tasks: the pectoralis major, the posterior deltoid, the biceps brachii, the triceps long head, the triceps lateral head and the brachioradialis.

"What is unique about our study is that we are the first group to measure metabolic cost in addition to muscle activity while performing a physical reaching task," said Huang, who performed most of the research and was first author on the Journal of Neuroscience paper. "The results are very surprising and challenge the widely held assumption that muscle activity entirely explains changes in metabolic cost."

The study suggests that efficient movements ultimately involve both efficient biomechanics and efficient neural processing, or thinking. "We suspect that the decrease in metabolic cost may involve more efficient brain activity," Ahmed said. "The brain could be modulating subtle features of arm muscle activity, recruiting other muscles or reducing its own activity to make the movements more efficiently."

The results could be applicable, for example, to stroke patients who have to re-learn to walk, Ahmed said. "The rehabilitation process should not necessarily stop if the patient reaches a plateau in performance," Ahmed said. Continued practice reduces the metabolic cost of the task, an indication the brain still may be learning something," she said.

"Using the robotic system, we can understand the principles underlying the control of human movement and can apply those ideas to design rehabilitation programs that may allow stroke patients to re-learn their movements faster, to retain that learning and to transfer that learning to other tasks as well," she said.

So whether it is playing a musical piece over and over again even after you have the notes and timing down cold, or throwing a ball or swinging a racket after your coach tells you things look great, there appears to still be a benefit to practicing, Ahmed said. "Just because someone can perform the task well doesn't mean there is not added benefit to continued practice."

Good aerobic capacity promotes learning

— Aerobic fitness has a favorable effect on cognitive functions. For example, physically active elderly people are less prone to aging-related cognitive decline than those who lead a sedentary lifestyle. An increase in physical activity raises both aerobic capacity and learning ability in both humans and animals. However, it is not known whether it is the aerobic capacity or the pleasure and enrichment of physical activity that promotes cognitive functions.

A study conducted by research groups at the University of Jyväskylä shows that aerobic fitness — not physical activity as such — promotes cognitive abilities.

– In this study, we used rat strains raised at the University of Michigan. They had been selectively bred over 23 generations for their endurance running capacity. Due to this breeding, there were natural-born long-distance runners and very poor runners. Results from a test that is a counterpart to the human maximal endurance test indicate that the difference between these strains was 500%, says Heikki Kainulainen, Professor of Exercise Physiology.

– Rats were trained in a discrimination learning test that measures flexible cognition. They were first taught to fetch a food reward in the presence of one tone and to ignore the other one. After learning this rule, the stimulus assignment was reversed and they were required to abandon the old rule and learn a new one, describes Dr. Jan Wikgren, Senior Researcher at the Department of Psychology.

It was found that rats with intrinsically high aerobic capacity clearly outperformed those with intrinsically low aerobic capacity. It must be emphasized that the animals were not given any physical exercise before the learning test. Thus, the results suggest that it is the aerobic capacity and not physical activity alone that is related to flexible cognition.

The results gave rise to many questions. Probably the most crucial seeks to determine the neurobiological mechanisms that mediate the effect of aerobic capacity on brain function.

– In future experiments we aim at studying the possible differences between these strains from the molecular to neurophysiological levels of analysis. Ultimately, we hope to investigate plausible exercise interventions that protect the brain from the detrimental effects of aging, Wikgren and Kainulainen explain. At least it is safe to say that physical activity is good for your brain at any age.
