However, recently, this accessible online information has been filled with enormous negative news or neutral news with negative headlines. Therefore, the current study conducted three experiments to examine how negative online news affects social trust and helping behavior. The results of experiment 1 showed that individuals were inclined to demonstrate an attentional bias on and perform a preference for the negative news during the eye-movement task and indicated that individuals were easily affected by negative online news compared with positive online news. Based on experiment 1, experiment 2 used the guiding effect of online news and found that relative to some readers who were presented with positive news, others who read negative news showed less helping behavior, and this relationship was completely mediated by social trust. In experiment 3, we changed the headline of every neutral news story into two versions, one with a neutral headline and another with a negative headline, and found more negative cognition, lower social trust, and less helping behavior when individuals read negative headlines. Results of the current study supported the general learning model and the social cognitive theory, which showed that negative news had an impact on individuals' cognition, such as social trust, and then influenced their helping behavior. In particular, negative headlines led to a severely negative effect on social trust and helping behavior.

Once formed, such views would remain relatively stable for a significant period of time and affect their teaching practice, the ability of their students to carry out inquiry learning as well as developments in corresponding techniques and mindsets. This research analyzed the differences in the level of understanding of inquiry teaching under the cloud learning environment (CLE) between high school physics teachers from Beijing, Taipei and Chicago. As part of the analysis, video recordings of four actual high school investigative physics course sessions were selected from the 4th Competition of Middle School Physics Teachers Instruction Skills held in 2014 and ranked by the high school physics teachers from the three different cities in terms of inquisitiveness of the course. Results revealed significant differences exist between teachers from the three different cities in terms of understanding of CLE-based inquiry teaching. Teachers from Chicago inclined towards the students' awareness of the problem as well as their ability to collect and question data. Teachers from Beijing, on the other hand, prioritized a procedural approach in inquiry and investigations for their students. Finally, teachers from Taipei shared characteristics from both cities. In essence, teachers from Beijing were more teacher-focused in their understanding of inquiry teaching, while teachers from Chicago were more student-focused. Teachers from Taipei, on the other hand, was somewhere in between. Cloud learning environment.Understanding of CLE-based inquiry teaching.

Behavioral curves and data obtained by the USS would help students understand where they had made mistakes during practical lessons and the exact times when incorrect process parameters were observed. This research was conducted during a course on manufacturing. The results indicated that the proposed USS was effective in improving student analysis and evaluation skills in manufacturing thinking, as well as the three psychomotor skills of guided response, mechanism and complex overt response. Student psychomotor skills also gained an overall improvement. Results also showed that improvements in student thought process also helped in the learning of psychomotor skills and that the USS helped improve the clarity of student thought process during practical operations. The improved clarity of thought allowed students to understand the reasons behind their thought process for them to make the necessary logical deductions. Through repeated reflection and practice, students would then be able to create works with personal creative elements. The functions of critical thinking in tertiary education The American Philosophical Association defined critical thinking (CT) as a purposeful and selfadjusting decision-making process. CT would include elaboration, analysis, assessment, prediction and explanation for the basis, concepts, methodology, standard or context for the final decision made (Facione, 1990). CT covers six cognitive skills of (1) interpretation, (2) analysis, (3) evaluation, (4) inference, (5) explanation and (6) self-regulation, and seven affective dispositions that include (1) the search for the truth, (2) open-mindedness, (3) analytical disposition,

Nevertheless, the most of them are a brand-new and stand-alone program that could influence users' teaching and learning experiences since users have to spend additional time and efforts to practice and maintain the tools or systems. In fact, in the era of Web 2.0, instructors and students are heavily immersed in various web applications daily, such as Wikis, Flickr, WordPress, and Google web applications, and familiar with the manipulation of these applications. Therefore, the well-known web applications could be a potential new way to engage the instructors and students in meaningful teaching and learning activities. Bearing this in mind, this study aims to apply well-known web applications to propose a web application supported learning environment for supporting classroom teaching and learning activities that can seamlessly enable instructors and students to meld with their daily use of Web 2.0 tools. Through the investigation of a case study, the results revealed that the instructor and students can administer teaching and learning activities efficiently and effectively. In addition, the learning motivation of participated students and interaction between each participant can also be facilitated through engaging in the proposed environment.

However, many concepts and knowledge in the material synthesis can be rather abstract and difficult to understand by the student learners. Experiments are limited in scope due to lack of equipment, control of toxic materials, and risks of chemical reactions, which often restricts student imagination and student involvement in practical training. These reasons often led to poor learning attitude and learning performance among the students. Rapid developments in Cloud technology and mobile devices have provided new opportunities for developing novel learning tools for material synthesis. This study aims to introduce interest factors as a strategy for promoting learning interest and practical skills among the students. Chemical symbols, experimental themes, texts, and interactive elements were utilized to develop a theme-based Mobile Learning APP for teaching the practical techniques of material synthesis. The Mobile Learning APP was then integrated into a problem-based learning activity. A quasi-experimental design was used to investigate the resulting learning effectiveness from using the developed Mobile Learning APP. Results show that the Mobile Learning APP provided a significant positive effect on learning performance and that most students showed favorable attitudes toward the usage of the mobile learning system.

In advance of nano-technologies, the geometry of coating particles will be fabricated as designed. Therefore, the effects of the geometry of materials on the coating quality should be considered in manufacturing processes. Surface roughness is one of the major indicators of coating quality. The correlation of geometry of coating materials and surface roughness on the performance of coated electrodes is presented in this paper. Three types of geometries are analyzed which are spherical particles, uniformly distributed columns, and random types. Besides the geometry of coating materials, the impact force resulting from spray jet will alter the surface roughness and is one of the important factors to coating quality. Therefore, the stability of coating jet is also studied. The findings show th...

This reading habit led them to be incapable of analyzing or integrating information they have received. Hence, knowledge management and critical thinking (CT) have, in recent years, become important topics in higher education. However, there are many web applications that may serve as effective teaching and learning tools. This study therefore proposed a blended learning environment that incorporated useful web applications within a knowledge transformation model to create an educational environment capable of improving CT and knowledge transformation for student users. A semester-long experiment was then conducted to evaluate this learning environment. Results revealed that the proposed approach was effective in improving student CT and knowledge transformation. Students were also satisfied with the courses and teaching methods used by the proposed learning environment which also effectively improved their learning motivation.

However, practicing and operation in real environment cannot be replaced by the method of e-learning such as multimedia and interactive simulations. The present e-learning system has very limited benefit for course of experiment and practical training, especially for the course which requires to experiment in clean room (ex. MEMS). Thus, the quality and quantity of industrial technology education cannot be improved. In order to overcome obstacles of traditional experiment and practical training course and enhance functions of present e-learning system, the study is going to take sensor network technology as foundation to developed web services system. The system is able to present the students ‘operation and results right away, thus students can be guided appropriately when they face problems during experiment and practical training. Besides, the system is able to record students’ learning process of experiment and practical training. These data of learning process will be helpful for building adaptive u-learning environment for skill-training.

In the last two decades, researchers have been studying the characteristics of a water-jet, and tried to control its cutting process. However, existing knowledge about water-jet cutting is still ambiguous. Thus, it cannot satisfy the requirement of precise control. In this paper, linear stability theory is applied to theoretically analyze the relationship of nozzle diameter and wave number in the water flow with the stability of the water-jet. Theoretical conclusions satisfy the experimental results obtained.

A study on development of an H-infinity robust control system for arc welding

Further, the modeling of the dynamics and design of the feedback control system require both advanced control theory and deep understanding of welding process principles. The feedback control system should be designed such that it can tolerate the variations in manufacturing conditions and the resultant process dynamics. This implies that robust control is a potential solution to address the conflict between the increasing demand of quality welds and the limited number of qualified personnel. Hence, this study develops a mathematical frame of robust control of welding processes for welding engineers who understand welding process principles and have elementary feedback control background. The control of the weld geometry is used as an example to demonstrate the details of the robust control principle and its implementation.

The extensive literature detailing all aspects of the magnetic braking is briefly reviewed, however little of this refers specifically to upright magnetic braking system, which is useful for industries. One of the major issues to design upright magnetic system is to find out the magnetic flux. The changing magnetic flux induces eddy currents in the conductor. These currents dissipate energy in the conductor and generate drag force to slow down the motion. Therefore, a finite element model is developed to analyze the phenomena of magnetic flux density when air gap and materials of track are varied. The verification shows the predicted magnetic flux is within acceptable range with the measured value. The results will facilitate the design of magnetic braking systems.

A series of experiments was conducted to explore how changes of welding parameters affect the strength of the weld for the thin stainless steel most often used in the industry. The experiment results show that workpiece exposure height must be above a minimum limit in order to prevent undesired joining. The strength increases as the current increases, with fluctuations, but still in the sufficient range. The minimum sufficient current for quality welds increases, while the minimum sufficient heat input decreases, as the travel speed increases.

One of the major issues to design upright magnetic system is to find out the magnetic flux. The changing magnetic flux induces eddy currents in the conductor. These currents dissipate energy in the conductor and generate drag force to slow down the motion. Therefore, a finite element model is developed to analyze the phenomena of magnetic flux density when air gap and materials of track are varied. The verification shows the predicted magnetic flux is within acceptable range with the measured value. The results will facilitate the design of magnetic braking systems.

A series of experiments was conducted to explore how changes of welding parameters affect the strength of the weld for the thin stainless steel most often used in the industry. The experiment results show that workpiece exposure height must be above a minimum limit in order to prevent undesired joining. The strength increases as the current increases, with fluctuations, but still in the sufficient range. The minimum sufficient current for quality welds increases, while the minimum sufficient heat input decreases, as the travel speed increases.
