The Effectiveness of Using Constructive Learning Strategies in Teaching English Language on Developing the Achievement of Grammar, Translation, and Critical Thinking Skills for the Third Grade Intermediate Students

The study aimed to reveal the effectiveness of the integration between some constructive learning strategies in teaching a unit of the English language course to collect translation skills, using grammar, and the acquisition of critical thinking skills for intermediate third grade students in Mecca. Also, it aimed to acknowledge the statistical differences between the modified averages for the study sample groups degrees in the dimensional collecting of grammar and translation skills at the knowledge of the grammar level and using it, and at the macro level for collecting translation and grammar skills after adjusting the old collecting, as well as the knowledge of the statistical differences between the modified averages for the study sample groups in the total telemetric for the critical thinking skills after adjusting the old collecting. To achieve the study objectives, the researcher used the semi-experimental method that had several experimental groups （four groups）, and applied it to a sample of intermediate third-grade students in the city of Makkah （99 students） in teaching the unit of the English language course, which is （Healthy Eating） in the second semester in 2011/2012. After using the appropriate statistical methods, the study came to a result that there are no statistically significant differences in the old implementation for the test of skills of academic achievement of grammar, translation, and critical thinking skills, and that there are statistically significant differences in the new implementation due to the four strategies. According to the results of the study, the researcher recommended a number of recommendations including： the necessity to focus on the constructive theory in teaching English language skills, the importance of expanding the use of the suggested integrative oriented and its development in the field of English language teaching, to hold an intensive training courses for teachers of the English language to train them on using the suggested integrative strategy, the emphasis on the importance of the curriculum activities which focus on the integration between the constructive learning strategies, the importance of expanding of scientific research in the field of integrative strategies, and the development of synthesis methods that combine two strategies or more.

Advances in Educational Data Mining Models and the Application of Its Algorithms

In order to find an effective way to improve the quality of school management,finding valuable information from students' original data and providing feedback for student management are necessary. Firstly,some new and successful educational data mining models were analyzed and compared. These models have better performance than traditional models( such as Knowledge Tracing Model) in efficiency,comprehensiveness,ease of use,stability and so on. Then,the neural network algorithm was conducted to explore the feasibility of the application of educational data mining in student management,and the results show that it has enough predictive accuracy and reliability to be put into practice. In the end,the possibility and prospect of the application of educational data mining in teaching management system for university students was assessed.
