In this study, we aimed to determine the extent to which secondary school students practise environmental ethics. To this end, we used a questionnaire-based survey to accomplish the purpose of the study. The study’s variables included knowledge, value, care, and responsibility in environmental ethics. We selected a sample of 180 students using systematic random sampling from a population of 347 Form Four secondary school students studying geography in Papar, Sabah, Malaysia. The findings showed that all study variables, knowledge, value, care and responsibility were at high levels. Furthermore, a multiple regression analysis revealed that the value and care variable in environmental ethics influenced the responsibility variable which contributed 14.5% and 2.7%, respectively to student’s environmental ethics. Based on the findings, we concluded that students who incorporate environmental ethics into their daily lives will successfully fulfil their environmental ethics responsibilities. The study’s implications suggest that environmental education in schools exposes students to environmental ethics and helps them develop more ethical and disciplined attitudes towards the environment.

The study discussed in this paper is a systematic literature review related to the role of dual language programme (DLP) in mathematics education which has been published within the last 5 years. This study was conducted to identify the distribution of DLP studies in terms of year of publication, the study context covered in previous studies, the context of study areas used, focus and trends of past studies, research methods used in previous studies and the role of language in school mathematics education. This review study followed the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) to analyze articles from Scopus and Web of Science. The findings of the study indicate that research trends in the implementation of the DLP on mathematics education for secondary school students showed an increase from 2017 to 2019. Most DLP-related articles are widely developed in the United States and Germany. The findings indicate that previous studies are more interested in studying the implementation of DLP in rural areas. Past studies have also preferred to use the design of either a qualitative study or a quantitative study to be implemented. Questionnaires, tests and interviews are among the research instruments that are often used for a study.
