Robbers Cave04:49

Robbers Cave

During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension could be...
Group Design02:01

Group Design

The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between the two are due to...
Comparing Experimental Results: Student's t-Test01:09

Comparing Experimental Results: Student's t-Test

The t-test is a statistical method used to compare the sample mean with a population mean or compare two means from two data sets. The test statistic is calculated from the standard deviation, mean, and number of measurements in the data set at a selected confidence interval and then compared to a table of critical values at this confidence level. If the test statistic is smaller than the critical value, the null hypothesis is accepted. In this case, we state that the difference between the...
Community Based Intervention01:30

Community Based Intervention

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

Stratified Sampling Method01:16

Stratified Sampling Method

Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
To choose a stratified sample, divide the population into groups called strata and then take a...

Summary
This summary is machine-generated.

The Strategies for Success intervention aimed to divert students from alternative schools to the justice system. While it improved attendance short-term, it paradoxically increased reassignments to alternative schools.

Problem-Solving Before Instruction (PS-I): A Protocol for Assessment and Intervention in Students with Different Abilities

Published on: September 11, 2021

Area of Science:

  • Educational Psychology
  • Criminology
  • Intervention Studies

Background:

  • Disciplinary alternative schools are often seen as pathways to the juvenile and criminal justice systems.
  • A significant concern exists regarding the long-term outcomes for students attending these schools.

Purpose of the Study:

  • To evaluate the effectiveness of the "Strategies for Success" intervention.
  • To determine if the program could divert seventh-, eighth-, and ninth-grade students from justice system involvement.

Main Methods:

  • Propensity score matching was employed to create comparable groups.
  • A multivariate random effects model was utilized to analyze program impacts.

Main Results:

  • The intervention demonstrated a short-term increase in student attendance rates.
  • However, the program also significantly increased the likelihood of students being reassigned back to alternative schools.

Conclusions:

  • The "Strategies for Success" program showed mixed results, improving attendance but failing to prevent re-entry into alternative schooling.
  • Further investigation is needed to understand and address the high rates of return and the diminishing effects of such interventions.
