This study concerns a framework for designing Teaching-Learning Sequences that aims to integrate the implementation of scientific practices in the context of daily problems. Said framework consists of three stages (formulation of the design principles, instructional design and design of the learning activities). It is based on four design…

During the semester break, 36 second-grade students accessed a set of resources and completed a series of online math activities focused on the application of the model method for arithmetic in two contexts 1) addition/subtraction and 2) multiplication/division. The learning environment first modeled and then supported the use of a scripted series…

A sequential testing model is proposed which employs discriminant functions to classify examinees into groups which could correspond to instructional treatments. A termination rule based on the computed posterior probability of group membership is suggested. (Author)

Shows how elaboration theory (ET) sequences the concepts in a taxonomy and argues that the product of an ET analysis is usually in general agreement with sequencing based on learning prerequisite relationships, and that ET sequencing of taxonomic concepts will not violate learning prerequisite relationships.

Twenty-seven kindergarten children were trained on two different double classification matrix tasks in an attempt to determine whether the tasks were hierarchically related. Prior behavior analyses of the tasks suggested that the two tasks shared many components, but that the more complex task had in addition components not included in the simpler…

The Primary Education Project (PEP) is concerned with the development and evaluation of a model of individualized education for young children suitable for implementation in American public schools at the preschool through primary grade level. It is concerned with all aspects of school functioning: curriculum, classroom organization, teacher…
