MS grade helium was used as carrier gas with a debit of 1 mL min−1. Electron ionization was performed at 70 eV with a detector temperature at 180 °C. The selected ions monitored with a dwell time of 20 ms and distributed in time windows were the following: Window 1—...
Likewise, Hoe and Ramanathan [12] found that Singaporean grade 9 students failed to build a firm understanding of the properties of acids and bases, strengths of acids and bases, pH, neutralization, indicators and sub-microscopic view of acids and bases. Sheppard [13] also indicated that acid...
The Students scores on the free-response questions are combined with the results of the computer-scored multiple-choice questions; the weighted raw scores are summed to give a composite score. The composite score is then converted to a grade on a 5 point scale: ...

Such differences in the electrochemical performance can be rationalized in terms of the synergistic effect between both metals (particle size distribution, grade of dispersion and hydrophilic behavior), which demonstrate that the incorporation of a different secondary metal plays an essential role in the...
(PBL) exerts a positive impact on student development. This study explores the development and changes of students across project-based learning units by qualitative research methods. We followed a student group (1 boy and 3 girls) from one class in grade 9 over 3 time points within 1 school...
