This tool is used to simulate acid-base reactions between various reagents proposed in the software. It must be pointed out that this tool requires an advanced knowledge of acid-base reactions, since there is no self-training available. One can also regret the absence of tutorial.

The purpose is to view the result of some experiences without the need to really make them, or compare experimental results with theoretical results.

The tool offers a great number of reagents (cations, anions, acids, bases, complexes...) the quantity and concentration of which can be specified.

The number of options offered is important and handling the tool is difficult for someone who does not have a deep knowledge of the subject.

The tool is used in two phases: a first one in which the species in the beaker is selected and its concentration specified. In the second one, the content of the burette and its concentration are selected.

When those two parameters have been selected, the software starts the reaction simulation and a result table appears. It is then possible to obtain charts based on the results provided by the software. Unfortunately, the latter item is not optimised and is quite complex to carry out.

Using it in the classroom is difficult, apart from comparing results or easily creating charts. At university, the software can be used by the professor to show various curves in order to visually support his speech. Using it in a chemistry practical course, also at university, is possible too.
L'outil proposé sert à simuler des réactions acide-base entre divers réactifs proposés dans le logiciel. Il est important de noter que cet outil nécessite une connaissance poussée des réactions acide-base, ce dernier ne permettant pas l'auto-apprentissage. L’absence de tutoriel est également à déplorer.

Le but est de visualiser le résultat de certaines expériences sans avoir à les réaliser réellement ou de confronter des résultats expérimentaux avec des résultats théoriques.

L'outil propose un grand nombre de réactifs (cations, anions, acides, bases, complexes...) dont il est possible de préciser la quantité ainsi que la concentration.

Le nombre d'options proposées est conséquent et il est difficile pour quelqu'un n'ayant pas une connaissance approfondie du sujet de maitriser l'outil proposé.

L'utilisation de l'outil se fait en deux temps : un premier temps lors duquel il faut choisir l'espèce présente dans le bécher ainsi que préciser sa concentration. Et un second temps lors duquel il faut choisir le contenu de la burette ainsi que sa concentration.

Une fois ces deux paramètres choisis, le logiciel lance la simulation de la réaction et un tableau de résultat apparait. Il est ensuite possible d'obtenir des tracés de graphiques sur base des résultats fournis par le logiciel. Malheureusement, ce dernier point n'est pas optimisé et est relativement complexe à réaliser.

L'utilisation en classe est difficile, mis à part pour confronter des résultats ou pour créer facilement divers graphiques. À l'université, le logiciel peut être utilisé par le professeur pour montrer diverses courbes afin d'appuyer ses dires par un support visuel. Une utilisation lors de TP de chimie, également à l'université, est aussi envisageable.
The strong points of the tool are its richness, the set of options offered and the possibility to draw charts directly, based on the obtained results.

The weaknesses are its difficult and complex handling for a lay person. A tutorial would have been welcome.

The results obtained during an experiment simulation are exact and precise.

At the teaching level, this tool can be used in the fifth year of secondary education at the earliest, and only with a teacher who knows all the concepts used in it. The tool seems to be perfectly suitable for university level.
Les points forts de l'outil sont sa richesse, l'ensemble des options qu'il propose ainsi que la possibilité de pouvoir tracer directement des graphiques sur base des résultats obtenus.

Les points faibles de l'outil sont la prise en main difficile et la complexité d'utilisation pour une personne non-initiée. Un tutoriel aurait été le bienvenu.

Les résultats obtenus lors d'une simulation d'expérience sont exacts et précis.

Au niveau pédagogique, l'utilisation de cet outil ne pourra se faire qu'au mieux en 5ème secondaire et uniquement avec un professeur maitrisant l'ensemble des concepts utilisés dans celui-ci. L'outil semble être parfaitement adapté au niveau universitaire.

Message: Is the teaching resource described useful for you? Why?
This application simulates acid-base reactions between various reagents. Possible choices and adjustable parameters are impressive. After overcoming the lack of sufficient instruction and tutorial, the tool is extremely useful for work with talented students, especially with good ICT skills. This is the great tool to compare experimental and theoretical results.

Do you think it can increase students’ interest toward chemistry? Why?
It is hard to determine. The application can be found as raw, even deterrent. I think that the interest can be increased only for special kind of students, with analytical inclinations. The problem need to be considered in wider context.

Do you think it can help students to understand better and faster? Why?
The profit from the tool is obvious and unquestionable, but, as it was mentioned before, for talented students. I suppose students not interested in chemistry can find the application as boring accounting software...

Do you think it proposes an innovative didactic approach? Why?
I can easily imagine very interesting lessons scenarios, based on the program. Its complexity and variety of customization is worth investigation. Unfortunately, with weak support of its author.

National Reports on successful experiences to promote lifelong learning for chemistry The national reports on chemistry successful experiences to promote lifelong learning for chemistry are now available on the related section of the project portal. The reports presents examples of successful experiences in the partner countries and the results of testing of ICT resources with science teachers.
