“…Additionally, this activity does not provide experimental data that can be visualized or analysed by students. The kinaesthetic learning activity described in this paper uses the Poxyz LPS which we have used in the past for physics instruction [17][18][19][20][21]. It has the capability to measure 1D, 2D, and 3D positioning, acceleration, angular velocity, magnetic field strength, and pressure.…”

For millennia, humans have observed planetary retrograde motion and attempted to explain the phenomena. Our modern understanding of the motions of bodies within the Solar System is built up from a rich history of past models, each of which tried to explain astronomical observations while also being influenced by the contemporary belief system. One of the pivotal observations that assisted astronomers in the development of our current planetary model is planetary retrograde motion. Complexities in heliocentric and geocentric planetary models coupled with the change of reference frame required to visualize retrograde can be challenging for students. For this reason, we developed a kinaesthetic learning activity for introductory physics and astronomy courses that requires students to physically walk planetary orbits and allows them to see apparent motions across a virtual sky in real-time. In this paper, we present multiple activities using a local positioning system that are based on changing historical models for the retrograde phenomenon. We aim for these activities to culminate in students’ holistic understanding of how astronomically observed retrograde patterns were explained by models stemming from the existing scientific knowledge and beliefs available at the time.

With the rapid development of social economy, the importance of ecological civilization is increasing day by day. The level of environmental monitoring will directly affect the control of total pollution sources and the evaluation of environmental quality. Crowd sensing is to use the group computing power of users with smart devices to quickly collect surrounding multidimensional data, analyze and calculate based on these massive perception data, and then dig out group behavior patterns and other regular information. In order to meet the basic requirements of environmental protection work put forward by the government in the new era, this paper proposes mobile positioning and crowd sensing technologies, explains the distribution map method and adaptive weighting data fusion related algorithms, and designs and develops a mobile positioning system based on mobile positioning. The system of crowd sensing of urban healthy street monitoring is designed, and then we use this PM2.5 monitoring system to monitor the relevant environmental data of a street in Shanghai and use normalization to process the experimental data. The experimental data and statistical results show that this performance of the system is good, and the accuracy of image PM2.5 monitoring reaches 90%–95%. More than 90% of street residents are also very satisfied with this system, believing that it can play a role in supervising urban healthy street.

“…The experimental setup consists of two, 10 m long, tug-of-war ropes linked together by a load cell and two mechanical swivels. In addition, the apparatus for the primary kinaesthetic activity includes a local positioning system (LPS) for tracking the rope movements [6][7][8]. Figure 2 contains a diagram showing the setup used for the tug-of-war experiment, as well as closeup photos of the load cell, couplings, and the tracking device.…”

“…They can then use the experimental apparatus to test their ideas. Only two instruments are used, a load cell to measure the force of tension in the rope and a local positioning system (LPS) to track the position of the rope [6][7][8]. This setup turns tug-of-war into an engaging activity for a physics class or science event conducted outdoors or in a gymnasium.…”

We present a kinesthetic active learning activity, based on tug-of-war, that challenges upper secondary education and undergraduate learners to engage with Newton’s laws. The learning module has two parts. In the first part students analyse the game using common introductory physics concepts. They use those insights to make predictions about what factors affect the outcome of the game. In the experimental part of the activity, students first use a load cell to measure the force of tension produced by pulling against a fixed object while standing on various surfaces. The effective coefficient of friction for each interface is calculated from this data. Next, students compete in, observe, and analyse a series of tug-of-war games in which the tension in the rope is again measured and a local positioning system simultaneously tracks the position of the rope. We present example data and results for these activities and compare them to the predictions. In particular, we show the tension force in the rope typically decreases as one team gains the upper hand. This is evidence that forcing the opposing team to lose balance, which makes it difficult for them to apply their maximum force, is a key factor in winning a game of tug-of-war.
