Although the understanding of English tense system is a crucial factor for communicative English learning and teaching for EFL students, it has been neglected over the years. As with other areas of the grammar, difficulties may arise from the nature of the system itself or from differences between time, tense and aspect. Consequently, many learners face a considerable difficulty with the English tense system as they are more often unable to grasp the basic conceptual differences of present/present continuous, past/present perfect, will/be going to along with many others. More concerning fact is that lots of instructors or so-called native English teachers seem not to be aware of the importance of teaching English tense system. The purpose of this study is to review and examine various theories and practical usages of tense in order to establish and/or present better methods for teaching tenses. This paper is focused on comparatively exact distinction of time, physical notion from tense, grammatical category as well as sequences of tenses in view of school grammar and communicative function. At the end or middle of each chapter, efficient teaching and learning techniques or strategies on tenses are suggested to help instructors or learners who relentlessly face confusions in understanding tense and its usage for communicative English learning and teaching. This study attempts to influence learners' ability to recognize and write tense in authentic contexts not to mention spoken English.

What strategies are used to help students understand quadratic functions in mathematics classroom? In specific, how does Chinese teacher highlight a connection between algebraic representation and graphic representation? From October to November 2009, an experienced teacher classroom was observed. It was found that when students started learning a new type of quadratic function in lessons, the teacher used two different teaching strategies for their learning: (1) Eliciting students to plot the graphs of quadratic functions with pointwise approaches, and then construct the function image in their minds with global approaches; and (2) Presenting a specific mathematical problem, or introducing conception to elicit students to conjecture, and then encouraging them to verify it with appoint approaches.

Recently there has been increasing emphasis on pedagogical content knowledge (PCK) for fostering science teachers' teaching professionalism that needs to be done from teacher training courses systematically. We investigated what were the PCK factors considered in planning instruction and the difficulties encountered in implementing it by pre-service teachers. In this study, 26 sophomores at an university of education in Gyeonggi province were asked to perform teaching demonstrations using scientific instruction models. They were also requested to write reflective journals and interview. Analyses of the results revealed that many pre-service teachers considered the teaching strategies such as the instruction organization and implementation when planning instruction. They had also regard to the learners' cognitive affective aspects, whereas the pre-knowledge of them was not properly considered. Especially, the curriculum and assessment were almost disregarded. Most of the difficulties encountered in planning instruction and implementing it were appeared in terms of the teaching strategies. For example, they had difficulties in considering the characteristics of each stage presented by the instruction models when planning instruction and implementing it. The frequencies of the difficulties in implementing experiment were especially higher than those of the other PCK factors. Educational implications of these findings are discussed.

The purpose of this study is to investigate what are objects in environmental education and to develop the teaching model for environmental education. The major objects of environmental education is how to teach students who not only take knowledge/skill, but also change their behavior with responsibility for environment. In order to change students' behaviors for environment, Hungerford recommended that teachers have teaching strategies with recognition, evaluation, and adaptation. Also, McCarthy developed teaching model to engage immediate personal meaning, to raise intellectual awareness of a concept, to enhance skills that students can use in their lives, and to foster personal adaptations. Based on the Hungerford's teaching strategies, and Mccarthy's 4MAT system, a teaching model is developed to encourage thinking skill, problem-solving ability, interesting, and participation in the class. The basic steps of the teaching model in this study are experience/recognition, knowledge/skill, evaluation, and adaptation/new experience and 8 sub-steps for instructional methodologies are developed to match of all students' learning style types in a classroom. This model will make it possible to raise the efficiency of instruction, and contribute to changing students who have responsibilities for their environmental behaviors. This model will be supplemented in schools, and applied to developing other instructional issues.

The present data-driven study attempted to explicate nonnative English teacher trainees' foreign language teaching anxiety in microteaching settings from their perspectives. It is assumed that nonnative English teachers or teacher trainees may experience anxiety not only as foreign language learners but also as foreign language teachers. In order to inquire into their anxiety, the researcher had 172 teacher trainees perform extended microteaching tasks and reflect on their teaching and anxiety through group discussion. Based on the analysis of their discussion, three aspects related to nonnative English teacher trainees' anxiety were identified. First, teacher trainees identified three main types of anxiety-provoking situations: communicative-competence-threatening situations, unexpected situations, and instruction-hindering situations. Second, they identified three sources of anxiety: limited ability to use English, lack of English teaching skills, and fear of criticism. Third, they were aware that they used diverse strategies to lower anxiety before and while teaching for different purposes. From their identification and awareness of anxiety-provoking situations, sources of anxiety, and anxiety-lowering strategies, they could reflect on professional qualifications as a foreign language teacher.

The purpose of this study is to investigate teachers' perspectives on content-based instruction (CBI) in English at a higher education in Korea. Based on the assumption that content-based instruction programs could be successful if teachers were actively involved not only in transmitting the content knowledge but also in students' development in the second or foreign language competence, the study explores teachers' treatments of language in relation to the students' language development in CBI classes. Research questions were related to five areas such as (1) the goals of CBI programs, (2) difficulties in CBI classes, (3) the use of native language, (4) teaching strategies and techniques, and (5) factors that affect the success of the CBI programs. Data gathered from 24 college instructors from a large university located in the metropolitan city of Korea. Results of the study indicated that college instructors of CBI programs had keen interest in developing students' language competence, experienced difficulties in designing course syllabus for mixed leveled group of students, rarely used Korean in class and used successful teaching strategies. Also factors needed to improve the CBI programs were recommended at the end of the study. Results of the study implied that teachers needed to be more aware of the students' learning process of English and to be more communicative with students in English in class. Further studies were needed in relation to the CBI courses for students of different age levels.

This study investigated the effects of teaching-learning lesson plan using cognitive acceleration instructional strategies applied to the unit, 'The Light and Shadow' in elementary school. Two classes of the second grade elementary students (N=63) in Chungcheongbukdo districts were assigned to control and treatment groups each, and were taught about 'The Light and Shadow' for 8 class hours. For the treatment group, teaching-learning lesson plan using cognitive acceleration instructional strategies developed by this research was applied. The traditional instruction by textbook and teacher's guides was used for the control group. All students were tested with the test for concept of the shadow and the test for academic achievement about the unit. As the result of the post-test, the scores of the treatment group were higher than those of the control group. However, it was not statistically meaningful difference. The scores of the treatment group were significantly higher than those of the control group in the delayed-post-test for concept of the shadow. No significant interaction was observed with respect to the students' gender, instruction and pre-level for the concept of the shadow. Data analysis indicated that the scores of the treatment group were significantly higher than those of the control group in the post-test and delayed- post-test for the concept of the shadow in the area of object permanence. Our research work shows the effectiveness of the teaching-learning lesson using cognitive acceleration instructional strategies for the development for concept of the shadow for elementary school students, and suggests the necessity for this kind of teaching-learning program in the fields.
