Why Do the Rich Get Richer? A Structural Equation Model to Test How Spatial Skills Affect Learning with Representations
نویسنده
چکیده
Spatial skills predict students’ success in STEM domains. This paper aims to better understand the difficulties of students with low spatial skills in using interactive graphical representations. I present a mediation analysis with test and log data from 117 students who worked with an intelligent tutoring system for chemistry. The analysis is based on (1) a knowledge component model that describes knowledge students acquire as they solve problems with graphical representations, (2) a search for features that describe students’ interactions with the representations and that are predictive of students’ learning gains, and (3) a structural equation model that tests whether these features statistically mediate the effect of spatial skills on students’ learning gains. Results show that only students’ ability to plan representations before they construct them mediates the effect of spatial skills on learning gains. This finding suggests that these students may need more support before they construct representations.

Under certain circumstances, the presumption that universal access to information infrastructure leads to greater equality of resources is incorrect, Iii fact, greater incquality can occur. This argument and several related propositions are explored through a formal theoretical model built on l'our simple assumptions: one cannot converse with everyone at the same time, information can be shared...

Test washback is held to be complex and multifaceted in that a host of cultural, social, individual, test, and institutional factors are involved in shaping it. Thus far, the majority of washback studies have had as their focus the role of teachers in test washback or washback to teachers. How educational environments or institutions might function in isolation or in interaction with other fact...

Freedom of access does not necessarily mean that information is freely shared. Thus universal access policies that provide only communication channels but do not also establish incentives for broader information sharing could widen the gap between information “haves” and “have-nots.” This essay develops access and collaborative network arguments through a formal theoretical model based on the i...
متن کاملDeformation of Outer Representations of Galois Group
To a hyperbolic smooth curve defined over a number-field one naturally associates an "anabelian" representation of the absolute Galois group of the base field landing in outer automorphism group of the algebraic fundamental group. In this paper, we introduce several deformation problems for Lie-algebra versions of the above representation and show that, this way we get a richer structure than t...
متن کاملSaliency Cognition of Urban Monuments Based on Verbal Descriptions of Mental-Spatial Representations (Case Study: Urban Monuments in Qazvin)
Urban monuments encompass a wide range of architectural works either intentionally or unintentionally. These works are often salient due to their inherently explicit or hidden components and qualities in the urban context. Therefore, they affect the mental-spatial representations of the environment and make the city legible. However, the ambiguity of effective components often complicates their...
