In this paper, the possibility of children studying by using an interactive learning technology called Pedagogic Conversational Agent is presented. The main benefit is that the agent is able to adapt the dialogue to each student and to provide automatic feedback. Moreover, according to Math teachers, in many cases students are unable to solve the problems even knowing the procedure to solve the...

So far, most of the applications of robotic technology to education have mainly focused on supporting the teaching of subjects that are closely related to the Robotics field, such as robot programming, robot construction, or mechatronics. Moreover, most of the applications have used the robot as an end or a passive tool of the learning activity, where the robot has been constructed or programme...

Children‘s literature books, more specifically, early counting books, can be an engaging means for exploring numeracy with young children. Although there is general consensus in the current literature supporting the integration of high-quality children‘s books to teach mathematics; a user-friendly instrument to guide the evaluation of early counting books does not exist. Consequently, I created...

The book is divided into two parts. Part I gives a vivid picture of the civil rights movement in Mississippi in the years 1961–1964. Moses not only conveys the drama of impoverished black Mississippians confronting the violence of whites determined to prevent them from voting, but also candidly and convincingly describes the difficult strategic and tactical decisions of organizers such as himse...

are non-zero. Solution: First suppose the above some has no non-zero entries on its diagonal. Since A(G)i,j is the number of walks of length k from i to j, if the sum above has non-zero diagonal entries, then for any pair of vertices i, j there is a walk of some length from i to j. This implies there is a path from i to j. Since i, j are arbitrary, we conclude that G is connected. Now assume G ...

The authors investigate how the labor market decisions of recent college graduates, new teachers, and employers affect the academic quality of the teaching workforce in public schools. They use a rich longitudinal data set of Missouri college graduates and public school teachers to examine the behavior of college graduates concerning an initial decision to secure certification and teach in a pu...

There is growing concern that improving the academic skills of disadvantaged youth is too difficult and costly, so policymakers should instead focus either on vocationally oriented instruction for teens or else on early childhood education. Yet this conclusion may be premature given that so few previous interventions have targeted a potential fundamental barrier to school success: “mismatch” be...
