Extension courses on practical work in Chemistry

On 17-19, 2016 in Shymkent Chemical-Biology Nazarbayev Intellectual school the extension courses on Chemistry practical works for NIS teachers was held by Cambridge consultant Alan Jarvis. In three days participants discussed features of certain practical works in accordance with subject programmes of 7-12 Grades.

The courses underlined the importance of safety measures during practical works, risk analysis guidance were studied. That analysis allows to concretely assess all consequences of practical works, to change the process of work, and to determine the competence of performer – whether teacher or pupil.

The trainer has repeatedly emphasized the necessity of providing detailed instructions and preliminary preparation of learners to carry out the work. Conducting practical work and discussion of the results were carried out in groups and pairs of learners. Teachers were engaged, they participated in the discussions, expressed their opinions. While performing the practical work Alan Jervis approached each group, explained the difficulties faced in the course of implementation and explanation of the experiment.

The practical works were held as follows:

  • Grade 7, «Sulphur and gland reaction» - importance and safety of practical work arrangement;
  • Grade 8, «Sodium thiosulfate and hydrochloric acid interaction» - study practical works as measures for improving skills;
  • Grade 10, «Metal cover» - safety of practical work, equipment exploitation, critical thinking skills;
  • Grades 10, 12, «Color connection of transitional metals» - continuity of secondary and high school subject programmes, specifics of holding and discussing results;
  • Grade 11, «Thermal effect measurement according to Hess law» - using different calorimetric methods for measuring energy changes;
  • Grade 12, «Acid-base titration» - the use of different devices and data loggers, etc..

In last day participants held micro-teaching lessons. They used obtained knowledge and skills within 20 min. lesson. Each participant not just held the lesson for the group of colleagues, but also received feedback (as comments) on the lesson.

After implementation and discussion of the practical work teachers were provided the opportunity to prepare a short introduction to practical work on any topic, and then they had to carry out microteaching in pairs. Each of the presentations was followed by a feedback, which allowed teachers to improve their methodology, and observing the work of colleagues allowed them to assess the approaches used.

Participants noted the high importance of this event, as chemical experiment plays an important role within the system of lessons among other forms of work.

The courses carried up at a high theoretical and practical level, the trainer explained in detail all the materials available, the necessary resources have been carefully prepared.
