TL;DR: In this paper, the authors proposed a learning program consisting of several features that enable the establishment of communication of students, teachers, and parents in synergy, thus collaboration in implementing learning can be formed so that the education received by the child to be optimal.
Abstract: The impact of technological developments, especially information and communication technology (ICT) has impacted on various aspects of life including education. The dynamics of technological development demand new ways and cultures in people's lives as 21st century skills are becoming an important issue today. Indonesia has made a revision and innovation of the curriculum in response to these demands but that effort is not as easy as turning a palm. The results of field studies show that there is an imbalance between the implementation and the outputs and outcomes of the established curriculum. One of the constraining factors is the lack of collaboration in learning, where learning is only left to the school or teachers. Innovation of science learning by using the concept of smart city to be an alternative problem solving proposed by researchers. The concept of smart city indicates transparency in the learning process so that parents can contribute related to the progress of their children. This learning program consists of several features that enable the establishment of communication of students, teachers, and parents in synergy. Thus collaboration in implementing learning can be formed so that the education received by the child to be optimal.

TL;DR: In this article, the authors used Routhian reduction to solve the dynamic equation of the tippe top with and without friction on the inner surface of a cylindrical with varying initial state based on maple.
Abstract: Physics computing can be used to help to solve complex dynamic equations, both translation and rotation. The purpose of this study was to obtain differences in the dynamics of the tippe top with and without friction moving on inner surface of a cylindrical with varying initial state based of Routhian Reduction. The equation of tippe top in flat fields with and without friction has been reduced by the Routhian reduction method with the Poincare equation with computational in the previous research, and computation has also been carried out in the search for numerical solutions to the dynamics of tippe top with friction in the Maple program. In this study the reduction used is a Routhian reduction, so that the equation used in determining the equations of tippe top motion with and without friction that moves in a curved plane in the form of a cylindrical surface with varying initial state based on maple is Poincare's equation based on Routhian reduction with and without friction. The effect of friction can be seen clearly through the dynamics and graph equations in the return top. This method can reduce the equation of backward motion with and without friction that moves on the surface of the cylinder clearly in the form of a set of differential equations. This research can be continued by solving the dynamic equations of the tippe top in other curved fields such as the torus and ball. The findings of this study are dynamic equations and graphs of friction with and without friction equations that move in curved fields in the inner of surfaces in cylinders with varying initial state based on maple.

TL;DR: In this paper, the potential energy of a nonholonomic Tippe Top with nonholonomous constraints is analyzed in a cylinder configuration space, and the authors propose a method to reduce the equation TT's motion with and without friction that moves on the surface of the cylinder to a set of differential equations.
Abstract: The formulation of the dynamics of a mechanical system can be done by the method of the Port Controlled Hamiltonia System (PCHS), but this method still leaves a Lagrange multiplier. Furthermore, the dynamics can be formulated using another method which is more systematic, namely the Routhian Reduction method. The method illustrates a system that is subject to non-holonomic constraints and external force, so that the Lagrange multiplier can be removed from the equation. Before formulating the dynamics of a non-holonomic mechanical system, the researcher will analyze the potential energy that occurs in a system that moves in the cylinder configuration space. Potential energy is the main part that must be completed to formulate the motion system of an object, because Routhian reduction only reviews the kinetic energy and potential energy in a dynamic system. The dynamical system reviewed is an object that moves both translation and rotation with a non-holonomic constraint, namely the Tippe Top (TT). The author analyzes the potential energy of a mechanical system that moves in a cylinder configuration space with non-holonomic constraints. Method in this research is a mathematical theoretical study. This method can reduce the equation TT's motion with and without friction that moves on the surface of the cylinder clearly in the form of a set of differential equations. According the result of this riset, the potential energy for the TT with non-holonomic constraints that move on the surface in the tube can be determined by U = mg(r(1 − cos ρ ) + (R − acos θ ) cos ρ + asin θ cos sin ρ), transforming the TT's Lagrangian that moves on a flat plane (Cartesian coordinates) to the tube coordinates, with reference to the height of the plane solved by coordinate transformation.

TL;DR: In the United States, in addition to native speakers of English who enter secondary schools with limited literacy, there has been a growth in middle and high school enrollments of English language learners who have limited literacy in both English and their native language as mentioned in this paper.
Abstract: By the time students in the U.S. have finished the elementary grades, there is an expectation that they will be able to read and write. Unfortunately, this is often not the case. In the United States, in addition to native speakers of English who enter secondary schools with limited literacy, there has been a growth in middle and high school enrollments of English language learners with limited literacy in both English and their native language.
TL;DR: There is much potential for the further development of web-based scaffolding in order to facilitate argumentation learning for LAs, and the co-constructions in the WAP were a main factor influencing the degree and sequence of the LAs’ improvements in using claims, warrants, and rebuttals.
Abstract: The present study developed a web-based argumentation program (WAP) to support the science concept and argumentation learning of low achievers (LAs) in socio-scientific issue (SSI) contexts. A quasi-experimental design was applied in the present study. A total of 63 eighth-grade LAs were defined as the experimental group, while 62 of their peers who were medium achievers (MAs) were defined as the control group. The WAP was developed based on three principles to address the specific needs of the LAs: visualizability, interactivity, and multiplicity. The statistical results showed that both the MAs and LAs exhibited significant improvements in both conceptual learning and argumentation learning. However, the LAs acquired better and more balanced improvement in their science argumentation learning. They even outperformed their peers in the MA group in terms of using level 1 claims and qualifiers in the WAP. Meanwhile, the qualitative analysis showed that both the LAs and MAs had no problems with using claims, warrants, or rebuttals. Most of the LAs basically saw the SSI argumentation as a competition and understood that they could potentially strengthen their arguments by citing evidence. However, they found it difficult to construct higher level qualifiers because they had difficulty perceiving the limitations of their own arguments. The co-constructions in the WAP were a main factor influencing the degree and sequence of the LAs’ improvements in using claims, warrants, and rebuttals. We subdivided their co-constructions into two types: opposed and supportive. The two types of co-constructions provided the students with various paths through which they can reflect on and evaluate their knowledge. This indicates that there is much potential for the further development of web-based scaffolding in order to facilitate argumentation learning for LAs.
