Molecular Models

43.8K
Physical models representing molecular architectures of chemical compounds play essential roles in understanding chemistry. The use of molecular models makes it easier to visualize the structures and shapes of atoms and molecules.

The Bohr Model

81.0K
Following the work of Ernest Rutherford and his colleagues in the early twentieth century, the picture of atoms consisting of tiny dense nuclei surrounded by lighter and even tinier electrons continually moving about the nucleus was well established. This picture was called the planetary model since it pictured the atom as a miniature “solar system” with the electrons orbiting the nucleus like planets orbiting the sun. The simplest atom is hydrogen, consisting of a single proton as the...

Stereotype Content Model02:16

Stereotype Content Model

15.5K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Compartment Models: Two-Compartment Model01:20

Compartment Models: Two-Compartment Model

7.2K
The two-compartment model divides the body into central and peripheral compartments to account for varying blood perfusion rates among organs and tissues, affecting drug distribution. The central compartment includes blood and highly perfused tissues with rapid drug distribution, while the peripheral compartment contains tissues with slower drug distribution. After a single IV bolus dose, the drug concentration is high in plasma and low in tissues. The drug distribution between compartments...

Clearance Models: Physiological Models

326
Drug clearance is a critical pharmacokinetic process involving the irreversible removal of drugs from the body through various organs over a specified time period. Physiological models are indispensable in determining organ-specific clearance, defined by the proportion of the drug eliminated per unit of time from the organ's blood volume.
The organ's clearance rate depends on the blood flow to the organ and the extraction ratio (E). The extraction ratio describes the organ's...

Area of Science:

  • Psychology
  • Educational Measurement
  • Cognitive Science

Background:

  • Existing psychometric models often overlook collaborative dynamics.
  • Group problem-solving requires understanding social combination processes.
  • Assessing teamwork is crucial for evaluating complex skills.

Purpose of the Study:

  • To extend psychometric models of individual assessment to collaborative settings.
  • To propose and evaluate a model for pairwise group work.
  • To inform the design and estimation of collaborative assessments.

Main Methods:

  • Utilized social combination theory to develop a theoretical framework.
  • Proposed a mathematical model for assessing dyadic collaboration.
  • Empirically tested the model using a twelfth-grade mathematics assessment.

Main Results:

  • Demonstrated the feasibility of applying psychometric models to pairwise collaboration.
  • Provided an empirical example of model estimation with student dyads.
  • Highlighted the implications for assessment design in collaborative contexts.

Conclusions:

  • The proposed model offers a viable approach to assessing group problem-solving.
  • Further research is needed to advance the assessment of collaboration and teamwork.
  • Findings support the development of more sophisticated collaborative assessment tools.
