Film has been used for education ever since educators recognized its powerful potential for learning. But its educational application has been criticized throughout the decades for underuse of the distinctive potential of film: to raise interest. To understand more fully film’s potential for learning, we propose a dynamic model of viewer interest and its underlying cognitive and emotional mechanisms (film’s interest raising mechanisms or FIRM model). In addition, we present an analysis method for assessing the interestingness of films in learning contexts. Our model marries interest theories from cognitive film theory and educational psychology and captures the dynamics of interestingness across a film as depending on a balance between challenge posed and coping potential provided.

A kind of theoretical analysis method in wall climbing robot design is presented in this paper. Using this method, a flexible wall climbing robot is developed that can be well adopted in small irregular places. Firstly, an optimization mechanism is given based on the effective utilization of aerodynamic attraction produced by a centrifugal blower. Kinematics model of the robot is represented, then linear velocity function and angular velocity function of the robot are deduced. Dynamic model based on Lagrange equation is established, which can be a theoretical foundation for control system design. Finally, simulation results show that the dynamic model and the method are reliable since the curves of driving torque match the change of negative pressure.

A new mathematical modeling method, namely, the finite element method and the lumped mass method (LMM-FEM) mixed modeling, is applied to establish the overall multinode dynamic model of a four-stage helicopter main gearbox. The design of structural parameters of the shaft is the critical link in the four-stage gearbox; it affects the response of multiple input and output branches; however, only the meshing pairs were frequently shown in the dynamic model in previous research. Therefore, each shaft is also treated as a single node and the shaft parameters are coupled into the dynamic equations in this method, which is more accurate for the transmission chain. The differential equations of the system are solved by the Fourier series method, and the dynamic response of each meshing element is calculated. The sensitivity analysis method and parameter optimization method are applied to obtain the key shaft parameters corresponding to each meshing element. The results show that the magnitude of dynamic response in converging meshing pair and tail output pair is higher than that of other meshing pairs, and the wall thickness has great sensitivity to a rotor shaft. In addition, the sensitivity analysis method can be used to select the corresponding shaft node efficiently and choose parameters appropriately for reducing the system response.

Nonverbal Information

In human communication, nonverbal information such as gestures and facial expressions often plays a greater role than language, and an increasing number of devices are designed to be intuitively controlled by gestures. However, there are some disadvantages of this intuitive interaction. One of the chief problems is that these devices have difficulty in distinguishing between unconscious and intentional gestures; they tend to respond erroneously to unconscious movements. In this chapter, authors propose a new gesture analysis method based on the dynamic model. They focused on the “exaggerated gestures” that are effectively used in, such as Japanese Kabuki, effectively used in Disney's animation, and tried to identify their common features and effects. They noted the “preparation” or “follow-through” motions just before and after the emphasized actions and each behavior can be quantified by the undershoot and overshoot value of changes in torque. These methods can provide important knowledge for analyzing features and distinguishing intentions when interacting with gestures.

The Impact

SUMMARYThis paper discusses the problem of impact with robotic systems. The original method for the solution of impact is presented. The main idea is the replacement of impact with a singularity and hence the approach is called the IVSA (Impact-Via-Singularity-Analysis) Method. This goal is achieved by considering the obstacle as a unilateral constraint and introducing the new set of generalized coordinates so as to incorporate the constraint in the dynamic model. Using the IVSA Method the impact is not described by algebraic equations but by a reduced set of differential equations resulting directly from the initial dynamic model. The integration of dynamic equations over the impact points is thus possible. A numerical example is presented.

This paper introduces the efforts of Michigan State University’s Counseling, Educational Psychology, and Special Education/College of Education (CEPSE/COE) Design Studio to utilize robotic telepresence devices in synchronous hybrid learning classes for the Educational Psychology and Educational Technology (EPET ) Ph.D. program. Robotic telepresence devices are digital devices that can be piloted from a distance for the purpose of interacting with people in a remote location. Synchronous hybrid learning classes refer to classes in which online and face-to-face students interact during shared synchronous sessions. This design case describes the context, technologies, and strategies used to integrate robotic telepresence devices in a synchronous hybrid learning class format. We conclude by discussing our insights gleaned from our existing designs for student telepresence in synchronous hybrid learning contexts.

Moreover, the simulation of Madymo testifies the simplified coupled dynamic model of seat-passenger interaction in frontal crash. Therefore, this model will be effective and feasible in predicting the performance of the seat in frontal crash during the initial stage of the seat development, for example, the performance of anti-submarining protection.

Abstract The Payakumbuh City of Rendang is an icon that reflects one of the typical traditional foods with beef, coconut milk, and different kinds of spices as the basic ingredients. The availability of beef is very important for the rendang industry to ensure the production process. The roles of breeders, wholesalers, retailers, and their distribution need to be managed properly from upstream to downstream. This study aims to analyze the availability of beef for the rendang industry in Payakumbuh City using a dynamic model. Survey research methods and dynamic model data analysis method with Powersim software were utilized. The availability of beef to meet the demand for the rendang industry in Payakumbuh City is still very dependent on the results of slaughtered cattle in Payakumbuh City. Imported beef supply is currently used as an alternative option to fulfill the beef needs for the rendang industry in Payakumbuh City.

And Coping

Navigating scientific challenges, persevering through difficulties, and coping with failure are considered hallmarks of a successful scientist. However, relatively few studies investigate how undergraduate science, technology, engineering, and mathematics (STEM) students develop these skills and dispositions or how instructors can facilitate this development in undergraduate STEM learning contexts. This is a critical gap, because the unique cultures and practices found in STEM classrooms are likely to influence how students approach challenges and deal with failures, both during their STEM education and in the years that follow. To guide research aimed at understanding how STEM students develop a challenge-engaging disposition and the ability to adaptively cope with failure, we generate a model representing hypotheses of how students might approach challenges and respond to failures in undergraduate STEM learning contexts. We draw from theory and studies investigating mindset, goal orientations, attributions, fear of failure, and coping to inform our model. We offer this model as a tool for the community to test, revise, elaborate, or refute. Finally, we urge researchers and educators to consider the development, implementation, and rigorous testing of interventions aimed at helping students develop a persevering and challenge-engaging disposition within STEM contexts.
