Soil is one of the most encountered physical evidence and can be useful in tracing the location of the crime scene. The discrimination of soils is fundamental to provide a link between a suspect and a crime scene. However, discrimination study of soils could be difficult due to interferences in the chemical fingerprint of soils obtained via a chemical instrumental technique. In this study, performances of four column-wise manipulations (CWMs) on ultra-performance liquid chromatography (UPLC) data of soils were evaluated. Both univariate and multivariate exploratory tools have been employed to elucidate discriminative capability of the preprocessed UPLC data. Results showed that CWMs hardly caused any positive impact to the UPLC data...

The use of ICT in teaching and studying mathematics helps students to develop mathematics. The practice's application, therefore, depends on different considerations, amongst which: teachers' expectations of their ICT teaching skills, instructor attitudes towards teachers in mathematics, teacher attitudes towards ICT contributions to student mathematics awareness. The research was undertaken to assess ICT integration readiness in the classroom in the Paracelis district for mathematics teachers at secondary schools. The thesis used a questionnaire with comments on any of the above variables. This questionnaire was forwarded to 15 mathematics teachers at Paracelis District secondary schools. It shows that ICT teachers' intervention in mathematics has an average limit of 4.06. It also ensures that mathematics teachers are confident and willing to use ICT in mathematics and mathematics instruction. The research results indicated that the controls and the sample groups were substantially di.....

Past studies have found that there are constraints on teachers in developing teaching and learning (TnL) resources to implement STEM education in the classroom. Based on this issue, this research has developed a platform containing a variety of STEM TnL resource materials that focus on the field of Discrete Mathematics learning. This field of study is an area of learning in KSSM Mathematics for form four students. It encompasses three titles, namely Logical Reasoning, Operations on Sets, and Network in Graph Theory. Discrete Mathematics was the focus in the development of this platform as it is often considered difficult for students to understand. Additionally, as teachers find it challenging to find suitable learning materials to get students to be more interested. The wide range of TnL STEM source materials contained in this platform makes it easier for teachers to choose and apply them in TnL. The ADDIE model was used as the development model for this platform. This model is among .....
