The purpose of this study was to investigate the effectiveness of the differentiated instruction in mathematics by a meta-analysis. Among the studies conducted for last twenty three years, the relevant 49 research articles were selected, 80 effect sizes were calculated for the cognitive domain and 70 effect sizes for the affective domain. Effect sizes were analyzed with school levels, student level, group organization method such as homogeneous vs. heterogeneous, class transfer and adjusting class sizes for each cognitive domain and affective domain. The results are as the followings: In the cognitive domain, the overall effect size of the differentiated instruction produced a medium effect(effect size=0.68, U3=75.17%). The differentiated instruction showed the highest effect size on elementary school and middle school, mid level students, heterogeneous group, class transfer and not adjusted class size. And in the affective domain, the overall effect size of the differentiated instruction produced a low effect(effect size=0.36, U3=65.36%). The differentiated instruction showed the highest effect size on elementary school, mid level students, and heterogeneous group. Thus the differentiated instruction was proved to be effective in mathematics classes.

A multicore system must be able to take full advantage of the program's instruction and data parallelism. This study introduces the data replication technique as a support technique to maximize the program's instruction and data parallelism. Instruction level parallelism can be limited by data dependency. In this case, if data is replicated to each processor core and used, instruction level parallelism can be used to the maximum. The technique proposed in this study can maximize the performance improvement effect when applied to scientific applications such as matrix multiplication operation.

The education effect of environmental impact cognitive instruction on high school students was investigated. Environmental values of students could be classified into egocentric, social-altruistic and biospheric values like those of Schultz’s three kinds of categories. The value distribution of students consists 44.7% of egocentric and biospheric value groups and 12.5% of social-altruistic value group, respectively. The environmental function such as knowledge and skill did not show remarkable differences between value groups. The environmental value only affected the attitude function. The biospheric value group had the higher attitude function than other value groups. The environmental impact cognitive instruction enhanced the environmental functions irrespective of the value group or instruction type. However, significant variables were different according to environmental functions. Environmental functions such as knowledge and skill were influenced by the instruction itself. The attitude function was dependent on instruction itself, value type and instruction type. The optimum application of the environmental impact cognitive instruction can be efficiently achieved through class division into egocentric value group and biospheric value group. Alternatively, the proper combination of instruction methods focused biospheric and egocentric impacts in a class can be recommended.

Research studies have shown that phonological awareness focused analogies and anagrams can be used as an effective game-based teaching instruction. However, previous studies used analogies and anagrams as separate instructional tools, especially in EFL-related situations. There has been no vocabulary learning in analogies/anagrams instruction provided, nor has there been usage of an integrated workbook for 'vocabulary learning and analogies/anagrams'. This study examined the effect on learners' vocabulary acquisition scores when a truly phonological awareness integrated 'analogies/anagrams and vocabulary learning' workbook was used as an instructional practice workbook. The results show that the phonological awareness integrated instruction significantly increased learners' vocabulary acquisition scores among 40 college students with minimal or basic level of English proficiency.

The purpose of this study is to develope a web site of statistics closely related to real life in the information society and to analyze the achievement and the response of the students about WBI between the web based instructiongroup and the traditional instruction group after applied the developed web site. The conclusions drawn from the results of this study are as follows: First, as compared the web based instructionclass with the traditional instruction class there was a significant difference in the high class but not in the low class. And there was a higher level of the achievement in the web based instruction classes than the traditional classes. Therefore, it is certain that the achievement will not fall through the web based instruction is applied. Second, the results of the investigated response using the paper sheets in order to see the response of the students about the web based instruction is that there was a more effect related to the interest and understand of studying in the web based instruction than in the traditional instruction. As synthesizing these study results, there will be a positive effect on the mathematical achievement as well as the interest of students about mathematics if the web based instruction is properly used.

The purpose of this study is to verify the effect of the method of English teaching and learning through the student-centered environmental instruction. I've been skeptical about the traditional instruction, which is composed of the teachers-centered instruction, because of the lack of creativity. Until now, I've always wished to have an alternative method that can be substituted for routine's style. To achieve it, I selected 90 students from 2 classes, in the 3rd year at a girls' high school in Chungnam as the subject of study. I divided them into two groups, the student-centered environmental instruction and the teacher-centered traditional instruction. The tools used in this study are a preliminary English achievement test, a self-directed learning attitudes test and two teaching plans. For this test, a high school text book was assigned. I have treated 20 times of the test each for two groups using two types of teaching-learning plans which I made for this purpose. To verify the hypotheses after administrating the test, I selected t-verification for post test result. Based on this test result, I could conclude that there was a significant improvement of English proficiency and a change in the self-directed learning attitudes; also the student-centered environmental instruction is more effective than teachers-centered instruction.
