Metabolomics applies multivariate statistical analysis to sets of high-resolution spectra taken over a population of biologically derived samples. The objective is to distinguish subpopulations within the overall sample population, and possibly also to identify biomarkers. While metabolomics has become part of the standard analytical toolbox in…

Heng, Chua Kah; Karpudewan, Mageswary – EURASIA Journal of Mathematics, Science & Technology Education, 2015
This quantitative study reports the effects of gender and grade level on secondary students' attitude towards chemistry lessons. For this purpose, the Attitude towards Chemistry Lessons Scale (ATCLS) was administered to 446 secondary school students between 16-19 years old. The ATCLS consists of four different subscales: liking for chemistry…

Scharfenberg, Franz-Josef; Bogner, Franz X. – Research in Science Education, 2013
This study classified students into different cognitive load (CL) groups by means of cluster analysis based on their experienced CL in a gene technology outreach lab which has instructionally been designed with regard to CL theory. The relationships of the identified student CL clusters to learner characteristics, laboratory variables, and…

Norton, Sylvia; And Others – 1985
To demonstrate that properly designed laboratory instruction does provide affective and higher order learning benefits, an experiment was carried out in two replications. The subjects were 80 students enrolled in General Microbiology at Wallace Community College, Alabama. Students were randomly assigned to experimental and control groups. The…
