The main purpose of this study was to investigate the effect of the Context-Based Approach (CBA) enriched by Prediction–Observation–Explanation (POE) on 5th grade students’ conceptual understanding of the States of Matter, Heat and Temperature. In this study, quantitative and qualitative data collection methods were employed. The quantitative element used a quasi-experimental design involving a non-equivalent pretest–posttest control group. This research was performed with a total number of 38 (N control group = 18, N experimental group = 20) 5th grade students (aged 10 to 11 years) in a school in a village located in the East Blacksea region in the 2016–2017 academic year. In the study, a two-tier concept questionnaire entitled ‘the States of Matter, Heat and Temperature (SMHTQ)’ and a semi-structured interview were used as data collection tools. In the experimental group, the topics were taught using the CBA enriched with the POE strategy while in the control group the topics were taught using the 5E teaching model (Engage–Explore–Explain–Elaborate–Evaluate) of the constructivist approach. The results indicated that the CBA enriched with the POE strategy was more effective in improving students’ conceptual understanding and reducing students’ alternative concepts than the 5E teaching model on the States of Matter, Heat and Temperature concepts. The results of the study provided helpful information for science teachers and researchers in science/chemistry education since the teaching materials used enriched the learning environment. Similar studies can be applied to different and wider sample groups and concepts.

This quasi experimental study examined the effect of technology based teaching approaches on the 6th grade students’ learning in social studies subject. The participants of the study included two classes of 6th grade students: control group (n=25) and experimental group (n=24) in one of the middle schools in Bhutan. The research instruments consisted of experimental group treatment, survey questionnaire and semi-structured interview questions. The result suggested that there is an affirmative effect of technology based teaching approaches on the 6th grade students’ social studies learning achievement test. It was found that mean test scores of the experimental group were higher than the control group on pretest and post test analysis. Further, the findings from the study established that students had a positive perception of learning through technology based instructions, as learners enjoyed, and were better able to understand, what has been taught. The findings from the study concluded that teaching through technology based approaches enhanced students’ learning in the classroom, so, it is recommended that teachers apply technology based instructions as a tool to maximize student learning. In addition, building of smart classrooms through digitalization could support students with learning difficulties in different subjects.

This study examined the effects of using Microsoft Mathematics on students’ attitude, conceptual understanding, and procedural skills in Differential Calculus. A quasi-experimental research design was used in which two different learning environments were compared. The participants of the study were two classes of Electrical Engineering students enrolled in Differential Calculus course, assigned randomly as control and experimental groups with 30 students in each group. The control group was taught using the traditional approach of teaching Differential Calculus while the experimental group was taught the same lessons using the Microsoft Mathematics embedded activity sheets. The experimental group learned through exploration and discovery of various concepts. The findings indicated that the participants had little understanding of the concepts and processes of Calculus prior to the conduct of the study. A significant improvement in their performances was noted after the experimentation. This suggests that the use of Microsoft Mathematics in teaching and learning Differential Calculus improves students’ conceptual understanding and procedural skills. It is also found that the use of Microsoft Mathematics in teaching and learning calculus is equally effective as the traditional approach. In terms of attitude, the experimental group demonstrated a “favorable” to “very highly favorable” attitude along the five (5) domains of the MTAS. A significant difference exists between the pretest and posttest attitude of the subjects on the domain “learning Mathematics with technology”.

Purpose: This study evaluated the effect of a teaching model to improve cultural competency (TMCC) for Korean undergraduate nursing students. Methods: A nonequivalent control group pretest/posttest quasi-experimental study was conducted with a convenience sample of 168 undergraduate nursing students in South Korea. The experimental group of 121 seniors was taught a 13-week teaching model in order to improve cultural competence. A control group with 47 junior students underwent nursing major courses, but did not take this teaching model. Before and after the program, students' level of cultural competency was measured using the Questionnaire for Cultural Competence (QCC) consisting of three sub-scales: "awareness and desire," "encounter," and "nursing skill and knowledge." Results: After the experiment, the experimental group showed significantly higher improvement in the Questionnaire for Cultural Competence in the three sub-scales of "awareness and desire," "encounter," and "nursing skill and knowledge" than the control group (p=<.050). Conclusion: A teaching model to improve cultural competence was effective in improving Korean undergraduate nursing students' cultural competency. Further studies need to be repeated in order to identify the effectiveness of the teaching model to improve cultural competency with graduate or clinical nurses.
