Stereotype Threat and Self-fulfilling Prophecies02:09

Stereotype Threat and Self-fulfilling Prophecies

37.5K
When we hold a stereotype about a person, we have expectations that he or she will fulfill that stereotype. A self-fulfilling prophecy is an expectation held by a person that alters his or her behavior in a way that tends to make it true. When we hold stereotypes about a person, we tend to treat the person according to our expectations. This treatment can influence the person to act according to our stereotypic expectations, thus confirming our stereotypic beliefs. Research by Rosenthal and...

Socioemotional Experience and Gender Development

25
Social-emotional experiences and cultural influences play significant roles in shaping gender development. During middle childhood, from ages 6 to 11, peer groups become dominant in reinforcing gender norms. Children in this age group often align with same-gender peer groups, which actively encourage behaviors that conform to traditional gender roles. For instance, boys may be discouraged from engaging in activities perceived as feminine, reinforcing culturally dictated norms about masculinity...

Multiple Bar Graph01:07

Multiple Bar Graph

5.1K
As the name suggests, a multiple bar graph is the same as a bar graph but has multiple bars to depict relationships between different data values. One can include as many parameters as possible. However, each parameter must have the same unit of measurement.
Each bar or column in the multiple bar graph represents a data value. These graphs are used primarily in interrelating two or more sets of data. The categories of different kinds of data are listed along the horizontal or x-axis, whereas...

Piaget's Stage 3 of Cognitive Development

537
During Piaget's concrete operational stage, from ages 7 to 11, children exhibit a marked increase in logical thinking skills, specifically in relation to tangible, real-world events. This stage is characterized by the development of several essential cognitive concepts, including conservation, reversibility, and classification, all of which support the child's evolving capacity for structured thought.
Conservation and Constancy of Quantity

Geometric Mean01:15

Geometric Mean

3.4K
The mean is a measure of the central tendency of a data set. In some data sets, the data is inherently multiplicative, and the arithmetic mean is not useful. For example, the human population multiplies with time, and so does the credit amount of financial investment, as the interest compounds over successive time intervals.
In cases of multiplicative data, the geometric mean is used for statistical analysis. First, the product of all the elements is taken. Then, if there are n elements in the...

Sign Test for Median of Single Population01:20

Sign Test for Median of Single Population

95
In general, the sign test serves as a nonparametric method to test hypotheses about the median of a single population when the data does not follow a known distribution. This simplicity makes it particularly useful for small sample sizes or when the assumptions of parametric tests cannot be met. The process begins with identifying a null hypothesis, typically stating that the population median equals a specific value. The alternative hypothesis could be that the median is either not equal to,...

Summary
This summary is machine-generated.

A 4-year study of over 2.6 million French students found that gender disparities in math performance emerge during the first year of schooling. This gap, favoring boys, appears linked to schooling rather than age, highlighting early education

Area of Science:

  • Educational Psychology
  • Developmental Psychology
  • Sociolinguistics

Background:

  • Gender disparities in mathematics are a global concern.
  • Early childhood reveals similar core knowledge in math between genders.
  • Sociocultural stereotypes, such as 'girls are bad at math,' are hypothesized to drive disparities.

Purpose of the Study:

  • To investigate the emergence and progression of gender disparities in mathematical performance.
  • To determine the timing and context (schooling vs. age) of this gender gap's development.
  • To identify the initial phase of schooling as a critical period for intervention.

Main Methods:

  • Longitudinal assessment over 4 years.
  • Inclusion of all French first and second graders (2,653,082 children).
  • Analysis of mathematical and language performance, considering family, class, school type, and socio-economic level.

Main Results:

  • Boys and girls showed similar math scores at school entry.
  • A significant gender gap favoring boys emerged after 4 months of schooling.
  • The gender gap increased with schooling, not age, with an effect size of ~0.20 after 1 year.
  • Findings were consistent across various demographic factors.

Conclusions:

  • The first year of school is identified as the critical period for the emergence of a math gender gap.
  • Schooling, not chronological age, is the primary driver of this disparity.
  • Findings provide a focused target for interventions aimed at preventing gender gaps in math.
