This applied research was designed to analyze the effectiveness of inquiry-based instruction as compared to teacher-directed instruction in 5th-grade mathematics and science courses at the subject school. The subject school modified mathematics and science curriculum for 3 years and became an Alabama Math, Science, and Technology (AMSTI) [2009] school. AMSTI provided extensive professional deve...

Ray-triangle intersection is an important algorithm, not only in the field of realistic rendering (based on ray tracing), but also in physics simulation, collision detection, modelling, etc. Obviously, the speed of this well-defined algorithm’s implementations is important because calls to such a routine are numerous in rendering and simulation applications. Contemporary fast intersection algor...

from applied linguistic point of view, the fundamental question facing the language teachers, methodologists and course designers is which procedure is more effective in fl/sl: learning to use or using to learn? definitely, in order to be a competent language user, knowledge of language system is necessary, but it is not sufficient to be a successful language user. that is why there was a gradu...

This paper presents a phenomenological diagnosis of the implementation ProDuct-based Instruction (PDI) in EFL’s writing class Thailand contexts. PDI is new instructional method for teaching business English writing. Its key products that are tangible and appeal to human senses; product’s tangibility serves as scaffold help students generate ideas stimulate analysis interrogations. The study foc...

Wiki use may help EFL instructors to create an effective learning environment for inquiry-based language teaching and learning. The purpose of this study was to investigate the effects of wikis on the EFL learners’ IBL process. Forty-nine EFL students participated in the study while they conducted research projects in English. The Non-wiki group (n = 25) received traditional inquiry instr...
