Education for Responsible Environmental Behavior: Evidence from Sri Lanka
environmental awareness environmental attitudes environmental behavior senior secondary students...
The present study examined the levels of four environmental dimensions; environmental awareness, attitudes towards recovery, attitudes towards recycling and environmental behavior among grade 12 students in Sri Lanka. A standard scale that has four environmental dimensions and personal information was used. Effects of gender, study stream, residential area and family income of students on each of the four environmental dimensions were determined by conducting Levene’s test, Kruskal Wallis H test, Dunnet’sT3 test and Mann Whiteny U test using SPSS for Windows version 26. Correlation analysis was run to reveal the associations among the four environmental dimensions. A sample of 1006 grade 12 students participated in the study. Students confirmed a moderate level of awareness, attitudes and behavior towards the environment. Girls’ levels in terms of all four dimensions were significantly higher than those of boys. The result strongly confirmed the impact of study stream on environmental awareness, attitudes and behavior of students. Awareness, attitudes and behavior towards environment of the rural students were at the highest level. However, no significant differences were observed among students from different family income groups. The observed weak correlation between environmental awareness and behavior confirmed that knowledge has not effectively transformed into environmental responsible behavior. Moreover, strong association could be observed between attitudes towards recycling and environmentally responsible behavior of the students. Observed positive correlations among four environmental dimensions indicate that students’ perceived environmental awareness and attitudes positively influence their responsible environmental behavior. These results emphasize the importance of incorporating essential environmental concepts and learning teaching strategies into the existing school curriculum to ensure students’ environmentally responsible behavior. Based on the present findings, suggestions were made for curriculum developers and educators to upgrade the existing curriculum.

Exploring Zimbabwean A-Level Mathematics Learners’ Understanding of the Determinant Concept
linear algebra matrix and determinant understanding...
Learners bring prior knowledge to their learning environments. This prior knowledge is said to have an effect on how they encode and later retrieve new information learned. This research aimed at exploring ‘A’ level mathematics learners’ understanding of the determinant concept of 3×3 matrices. A problem-solving approach was used to determine learners' conceptions and errors made in calculating the determinant. To identify the conceptions; a paper and pencil test, learner interviews, and learner questionnaires were used. Ten learners participated in the research and purposive sampling was used to select learners who are doing the syllabus 6042/2 Zimbabwe School Examination Council (ZIMSEC). Data was analyzed qualitatively through an analysis of each learners' problem-solving performance where common themes were identified amongst the learners’ work. Results from the themes showed that Advanced level learners faced some challenges in calculating the determinant of 3×3 matrices. Learners were having challenges with the place signs used in 3×3 matrices, especially when using the method of cofactors. The findings reveal that learners had low levels of engagement with the concepts and the abstract nature of the concepts was the major source of these challenges. The study recommends that; teachers should engage learners for lifelong learning and apply some mathematical definitions in real-world problems. Teachers should address the issues raised in this research during the teaching and learning process. In addition, teachers should engage learners more through seminars where learners get to mingle with others from other schools.

A Study of Students’ Self-Efficacy in Mathematics Performance Based on Bugis Ethnicity and Gender
bugis ethnic gender mathematics performance self-efficacy...
The study on mathematical performance was significant enough to be studied further to measure students' self-efficacy. Although studies on student self-efficacy in math performance from a gender perspective were abundant, studies on this relationship from the perspectives of ethnic culture and gender were scarce. Therefore, the objective of this study was to examine the self-efficacy of Bugis Junior High School students in solving math problems based on gender. The researchers used an algebra problem in the context of the Bugis ethnic culture. For this data set, two of 25 students at a public junior high school in Bone, South Sulawesi, Indonesia, were interviewed based on ethnicity and gender. Qualitatively, the triangulation technique was employed for data analysis. The study results revealed that male students outperformed girls in terms of self-efficacy, namely magnitude, strength, and generality, in math performance. Furthermore, female students had lower self-efficacy in terms of confidence, supportive experience in completing math tasks, and confidence in their ability to complete math tasks in similar or different contexts, compared to male students, who had higher self-efficacy. This result provided new knowledge by exploring the characteristics of students' self-efficacy by integrating ethnicity and gender.

Namibian Teachers’ Behavioural Intentions on Students’ Mathematics Learning Using Their Own Devices
behavioural intention mathematics perceived ease of use perceived usefulness price value...
Bring your own device (BYOD) policy implementation in schools worldwide has allowed students to learn subjects, including mathematics, using personal mobile devices (PMDs). PMD use has enhanced students’ mathematics enjoyment by bridging the gap between theoretical mathematics concepts and their practical applications, which makes mathematics more meaningful and leads to improved results. Nonetheless, students in Namibian basic education are not authorised to learn with PMDs in school. While students’ PMD use in school remains a topic of debate, there remains a need to investigate its impact on students’ mathematics learning and teachers’ perceptions of BYOD in mathematics classrooms. This study evaluated the perceptions and intentions of 209 Namibian mathematics teachers from the Omusati and Khomas regions regarding students’ mathematics learning using PMDs in schools. Data were collected through an online survey. A structural equation model revealed teachers’ positive intentions towards students’ use of PMDs through BYOD in learning mathematics in school. Perceived usefulness (PU), perceived ease of use (PEoU), and price value (PV) factors directly affected the teachers’ behavioural intentions (BI) towards students learning mathematics through BYOD. PEoU significantly affected teachers’ PU, and PV significantly affected teachers’ PEoU and PU. PU significantly mediated the relationship between PEoU and teachers’ intentions. PV significantly indirectly affected teachers’ intentions through PU. PEoU non-significantly mediated the PV and intention relationship. Practical implications are discussed, and recommendations are offered for the Namibian Ministry of Education, Arts and Culture and teacher training institutions.
