The quest for better strategies in teaching is a never-ending process. This scenario is heightened more by the myriad online instructional materials fit for classroom use. The study aimed to determine the effectiveness of video lecture materials for statistics proficiency of first year students of Davao Doctors College.The researchers employed quasi-experimental design that involved purposively chosen 31 students for the control group and 26 students for the experimental group. The control group received traditional instruction while the experimental group utilized video lecture materials as the instructional tool. The questionnaire consisted 50 multiple choice items and established a reliability index of .82. This investigation used t-test analysis to establish the same level of statistics proficiency among the students before the conduct of the study. The study concluded that both learning strategies were effective in teaching students the basic concepts of statistics as indicated by the significant improvement of their pre-test to posttest scores. Although the posttest results of the students who were taught using video lecture materials were higher than those supervised using lecture method, the significance of this difference was never established. Thus, the use of video learning material as an instructional tool in statistics is equally effective with the traditional lecture method. Keywords - Mathematics education, video lecture material, effectiveness, statisticsproficiency, quasi-experimental design, significant difference, t-test, Philippines

This study was conducted with the aim of investigating the impact of instructional conversations on oral autonomy of Iranian English as Foreign Language (EFL) learners. Forty-nine Iranian intermediate EFL learners from three language institutes in Sarakhs were selected as the participants of the study based on their scores in Nelson Proficiency Test. Administering Nelson General Proficiency Test, participants were measured to make sure they are homogeneous. These participants were randomly assigned into to control and experimental groups.  Participants in both groups sat for Learner Oral Autonomy Questionnaire with some modifications from Kashefian's learner autonomy questionnaire (2002). Results of independent samples t-test lack of any significant difference between the two groups in oral autonomy at the outset of the study. Throughout the study which lasted for 12 sessions participants in experimental group received the treatment, instructional conversations, as a tool for teaching speaking materials. Participants in the control group were taught the same materials as those practiced in the former group through such techniques as role playing, peer dialogues, and oral presentations. Finally, the posttest being the same as the pretest was administered. Results of independent samples t-test showed that the experimental group significantly outperformed the control one in Oral Autonomy Questionnaire. The present findings provide pedagogical implications for employing instructional conversation in EFL speaking classrooms.

The COVID-19 pandemic has significantly disrupted education and has instantaneously shifted education from being conducted predominately ‘face to face’ to being totally ‘online’. For most teachers, this unexpected teaching approach has impelled them into finding ways to provide the same quality of education to their students. One way of doing this is by adopting educational technologies in learning and teaching, including the use of augmented reality (AR) technology. AR technology has been integrated into the field of physics education. In this study, the effects of AR technology on understanding of the concepts of electricity in an online learning environment for 11th-grade students was investigated. Pretest and posttest were carried out in the control group and the experimental group. The results showed that AR technology improved understanding of electrical concepts for the students in the experimental group compared to the control group, with a very significant difference between both groups. This research contributes to the development of AR technology in education, especially in relation to the teaching and learning of abstract physics concepts.
