The sample was initiated at the time of the Census, and the four dates were used to update the sample at theand Censuses and in routine event registrations.

However, preschool programs tend to either be teacher-led and didactic, or else to lack academic content.

One preschool model that involves both Longitudinal case study advantages, freely chosen activity and academic content is Montessori. Here we report a longitudinal study that took advantage of randomized lottery-based admission to two public Montessori magnet schools in a high-poverty American city.

The final sample included children, 70 in Montessori and 71 in other schools, most of whom were tested 4 times over 3 years, from the first semester to the end of preschool ages 3—6on a variety of cognitive and socio-emotional measures. Although not different at the first test point, over time the Montessori children fared better on measures of academic achievement, social understanding, and mastery orientation, and they also reported relatively more liking of scholastic tasks.

They also scored higher on executive function when they were 4. In addition to elevating overall performance on these measures, Montessori preschool also equalized outcomes among subgroups that typically have unequal outcomes. First, the difference in academic achievement between lower income Montessori and higher income conventionally schooled children was smaller at each time point, and was not statistically speaking significantly different at the end of the study.

Second, defying the typical finding that executive function predicts academic achievement, in Montessori classrooms children with lower executive function scored as well on academic achievement as those with higher executive function. This suggests that Montessori preschool has potential to elevate and equalize important outcomes, and a larger study of public Montessori preschools is warranted.

Introduction Optimizing preschool education is important from both economic and developmental standpoints Heckman, ; Blair and Raver, The human brain undergoes marked development in the first 6 years, and the environment interacts with gene expression producing changes that appear to be permanent Zhang and Meaney, Furthermore, neural development proceeds in a hierarchical fashion, with later attainments built on earlier ones Merzenich, Economic analyses show that the highest rates of return on educational investments in human capital are derived from preschool programs Heckman, Yet the two primary examples of successfull early childhood interventions Perry Preschool and the Abecedarian Project are from the s Campbell et al.

Doing such interventions at scale would be exceedingly difficult. However, some alternative public preschool programs can feasibly be widely implemented; one such program is Montessori. Montessori education aligns with principles and practices that a century of research has shown are more optimal for child development than the principles and practices that undergird conventional schooling Lillard, Developed by a physician in the first half of the 20th century, the educational method stemmed from close observation of children in relatively free environments.

Within a structure created by the materials and teacher oversight, children are free to make constructive choices among activities that they have been taught, to explore personal interests with the caveat that they also engage broadlyand to decide whether to work alone or with peers in the multi-age classrooms.

There are no grades or extrinsic rewards, and learning is situated in real or simulative contexts. Montessori education is aimed at development of the whole child, integrating social and cognitive growth for healthy independent functioning. Program quality is clearly an important consideration, as children in higher-fidelity Montessori classrooms where children had only Montessori activities had larger social and cognitive school-year gains than those in lower-fidelity ones Lillard, However, the Lillard study had serious limitations, including that the children were middle-income and not randomly assigned to the schools, which were private.

Such limitations are common in the relatively few existing studies of Montessori education Rathunde and Csikszentmihalyi, ; Peng and Md-Yunus, Another study avoided these problems by testing 5-year-olds in a high-fidelity public inner-city Montessori school who had gained admission through a computerized district-level random lottery when they were 3 years old, and compared their outcomes to those of 5-year-olds who had lost that lottery and were at non-Montessori schools Lillard and Else-Quest, The Montessori children significantly outperformed the control children on an array of measures.

These limitations are also problematic. In the present study, children in two high-fidelity public Montessori magnet schools 11 classrooms who had gained admission via a random computerized district-level lottery at 3 years old were compared to a group who had lost the lottery and attended other non-Montessori schools, over half of which were private schools.

The tests, described next, assessed a variety of skills known to be important to later success. For young children, initial progress in reading, vocabulary, and numerical understanding are valued indicators.

The Woodcock-Johnson tests have good psychometric properties as described in the manual, and are frequently used to measure school outcomes. Social cognition was measured with the Theory of Mind scale Wellman and Liu,which has good internal and external validity Wellman, ; for example, it predicts later social competence Wellman, A central construct in the Theory of Mind scale is understanding of false belief, which has garnered considerable attention in developmental psychology and education in the last 30 years Blair and Razza, The Theory of Mind scale contextualizes this key understanding with steps leading up to it understanding of perception and its relation to knowledge, and understanding that people can believe different things and following it understanding that the emotions we convey might be different from the emotions we actually feel.

Although theory of mind is related to social competence, they are different constructs. Other studies have shown that children in high-fidelity Montessori preschools show more social competence on this task as well as better playground interactions than children in other types of preschools Lillard and Else-Quest, ; Lillard, Theory of mind is also strongly associated with executive function and involves many of the same neural structures for example the medial and lateral prefrontal cortex and the temporo-parietal junction Carlson and Moses, ; Koster-Hale and Saxe, ; Powell and Carey, Executive function was measured in this study because it undergirds self-regulatory skills that are important to academic and life success Blair and Razza, ; Diamond, ; Vernon-Feagans et al.

Here executive function was measured with two tasks; a full battery of tests would have been desirable Willoughby et al. One executive function task was Head-Toes-Knees-Shoulders HTKSin which a child must do the opposite of a command for example, touch their toes when asked to touch their head.This international conference will bring together scholars and research professionals involved in the design, implementation and analysis of longitudinal surveys, to share methodological research findings and to discuss the state of the art in carrying out longitudinal surveys.

List of Advantages of Longitudinal Studies. 1. They can show clear variable patterns over time. One key advantage of performing longitudinal studies is their ability to show patterns of a variable over time, which is a very powerful way through which researchers come to learn about the relationships of cause and effect.

More chapters in Epidemiology for the uninitiated. In a longitudinal study subjects are followed over time with continuous or repeated monitoring of risk factors or health outcomes, or both.

Longitudinal and Cross-Sectional Studies: Advantages and Disadvantages The key advantage to longitudinal studies is the ability to show the patterns of a variable over time. This is one powerful way in which we come to learn about cause-and-effect relationships.

Naturalistic observation is a research method commonly used by psychologists and other social scientists. This technique involves observing subjects in their natural environment. This type of research is often utilized in situations where conducting lab research is unrealistic, cost prohibitive or would unduly affect the subject's behavior.
