Esta corriente es especialmente importante en las orientaciones metodológicas que los expertos proponen a los docentes de las asignaturas de ciencias, estimulando la comprensión frente a la mera memorización, esto es, desarrollando habilidades cognitivas de orden superior, de acuerdo con la taxonomía de Bloom de los objetivos didácticos.Ī este respecto, los laboratorios virtuales ofrecen simulaciones dinámicas e intuitivas cuyo uso en asignaturas de ciencias está actualmente en boga. Se pretende fomentar con su uso una mayor implicación por parte del alumnado, lo cual constituye la base del constructivismo, que persigue el aprendizaje activo y significativo.

As a result, it was determined that the occupied area is between 6% (for 20 mg chitosan g−1 cotton)‐24% (for 100 mg chitosan g−1 cotton) from the total area of cotton. Finally, the percentage of the area occupied by chromium ions on the surface was estimated by dividing the resulting specific surface area in terms of cotton mass by the specific surface area of cotton reported in literature. Moreover, three different cross‐sectional areas of hexavalent chromium ions were calculated and used to estimate the specific surface area employed by active sites to adsorb metal ions in terms of chitosan or cotton mass. The most probable energy of adsorption corresponded to a physisorption with hydrogen bond interactions between chromium ions and ammonium groups. The kinetics of pseudo second‐order, pseudo first‐order, and adsorption isotherms type II were obtained, that is, a monolayer adsorption on nonporous adsorbents with physical adsorption was present. The adsorption of hexavalent chromium ions from water on the grafted chitosan was evaluated to determine, by means of linear and nonlinear models, the kinetic and isotherm adsorption of the process. It features a very basic UI design, however, lacks additional export options and does not come with any documentation.Chitosan was grafted on the surface of a cotton gauze (20 mg chitosan g−1 cotton, 50 mg chitosan g−1 cotton, and 100 mg chitosan g−1 cotton) to improve its stability in aqueous solutions. On the whole, Quantum Calculator is a handy utility that can help you with several scientific calculations. The lack of documentation may not be an issue if you are already familiar with all the specialized terms, but it still would have helped if at least a basic user manual or some tooltips were available. The UI’s minimalistic design makes the application pretty straightforward to use, but it also gives it a very outdated appearance. Features a simplistic user interface and lacks documentation Of course, you can use the Windows Print to PDF function to save them to PDF files, but exporting them as images is not possible. You can print these charts very easily, but there are no other export options available. Once you’ve entered a set of values and clicked the corresponding button, the program creates a chart that illustrates the sine and cosine waves, resulting wave amplitudes or probability amplitudes. Generate and print charts with a couple of mouse clicks Lastly, this program enables you to calculate the bunching probabilities for bosons and fermions based on the provided probability amplitudes. Secondly, you can use this program to calculate the results of interference between two waves with amplitudes you have chosen for bosonic and fermionic wavefunctions. For starters, it can plot the side and cosine version of a wave with a user-defined amplitude, and then generate a chart. This utility can help you with several calculations. However, it is worth noting that no documentation is included. The program features a minimalistic user interface that looks quite outdated, but its layout is straightforward enough. It can be used to perform various calculations and generate quick charts that can be printed instantly. Quantum Calculator is a fairly simple application based on quantum physics equations.
