Information and Communication Technology (ICT) has improved education widely in China, transforming traditional teaching into an interactive one. It is important to build a new evaluation model to measure teaching efficiency in an "ICT-enabled classroom". This study designed an evaluation model named "TPOCME Deep classroom" through ongoing five iterations. It includes six dimensions, which are higher-order Thinking, classroom Participation, Openness of educational system, Cooperative learning, Meaningful learning and Effectiveness of technology use (named TPOCME). This model helps educational researchers and teachers gain a comprehensive understanding of ICT in education.

The overall appeal of ICT in education in China is promoting deep integration of ICT technology with teaching. From a regional point of view, intelligent terminals, such as laptop and tablet, were integrated into classroom, in Beijing, Shanghai and other developed cities. Interactive media equipment (whiteboards, interactive TVs and iPad, etc.) have been applied in classroom teaching with deeper and broader ways. However, regarding the pedagogy, it is still a challenge to apply ICT technology for the revolution and further development of classroom instruction properly. In order to evaluate the quality of classroom teaching in an ICT environment and support teachers teaching with ICT technology in daily life practices, this study explored, measured and analyzed the features of classroom instruction in ICT environment, according to the sample lessons from a district in Beijing. Based on our prior research findings on Pad-enhanced teaching pedagogy, the "TPOCME Deep Classroom model" was proposed. 66 sample lessons that applied the TPOCME model were analyzed. The study found that student's Higher-order Thinking, Classroom Participation and Meaningful learning all have qualitative improvement compared with the traditional classes. The progress concerning the integration of ICT in education and teaching changes the relations between teaching and learning in traditional classes. This study also proved the effectiveness of the proposed model and provided a basis for further development. It was an exploration of promoting ICT-enabled classroom teaching pedagogy in China.

After a long period of geological tectonic action, the rock mass develops defects such as pores and fissures of different sizes and scales. The mechanical properties of the rock are largely affected by these discontinuous structures, and there will be obvious stress concentration at the edge of the hole inside the rock. Under the action of concentrated stress, cracks initiate, expand, and penetrate from the edge of the hole to form the final fracture surface and cause instability and failure of the rock mass. In practical engineering, due to the limitation of various factors, it is impossible to conduct uniaxial compressive strength test for each geotechnical engineering. Therefore, the rock in the weak part of the project can be selected as the test specimen before the indoor physical tests. In this paper, the static uniaxial compression test of specimens with circular holes with different diameters is carried out. Digital Image Correlation (DIC) monitoring system is used to observe the test process in real time; then, the data from uniaxial compression test and DIC monitoring test are obtained. At the same time, the macroscopic failure characteristics and crack propagation law of rock specimens are obtained, and the evolution law of strain field during the failure process of rock specimens is also obtained. Meanwhile, Realistic Failure Process Analysis (RFPA) is carried out to verify the accuracy of static uniaxial compression physical tests numerically. Physical tests show that the uniaxial compressive strength of marble specimens with circular holes and the dispersion of measured peak stress data decrease with the increase of hole diameter. The main failure type of marble specimens with circular holes is tension shear failure; the macroscopic failure zone of the sample, the strain field localization zone, and the maximum shear stress field of the numerical test are distributed in a semi-“X” shape with the hole as the center. The localization zone of the strain field on the specimen is usually the region of crack initiation, propagation, and penetration on the surface of the marble specimens. It also shows that specimen breaks in the radial direction along the y-axis of the circular hole, and cracks connecting both ends of the circular hole and the specimen are generated on the specimen. It is of great theoretical value and practical significance to the influence of the cavities in the rock specimens on the stress and strain characteristics and the initiation, propagation, and penetration modes.
