INNOVATIONS IN SCIENCE TEACHING

Imagining and acting like a scientist”- the very ideology to be impregnated into the attitude of a student. The very workflow in the process of science teaching have been like: Concept-> Process -> Social implication. Going beyond the content; teaching science would be a way of knowing. A process of unlearn the misconceptions among students to relearn the scientific processes

                Every aspect of our day to day lives is hugely influenced by scientific changes happening around us. The most causative catalysts for these changes are revolutionary advancement in information technology and communication along with globalization. Socio-economic changes intermingling with the scientific advancement in real life caters to open up enormous scope of learning before the new generation. This also creates some challenges to the new generation teachers. Knowledge of some new skills side by side with the traditional skills become inevitable such as – logical thinking and problem-solving, creativity and innovation, communication and co-operation.

            Presently all the Teacher Education programs aim to incorporate all these essential skills in the methodology of teaching process. The future teacher can cater their services purposefully to help overall development of their learners. The tasks of science teacher also include them to inculcate science education amongst the learners of various levels. The school level science classrooms are the hatching field for learners who will take science in their higher studies. The very science of science teaching emphasizes on innovation greatly. Some innovative strategies of science teaching are discussed here.

  • Project-based learning:

            Adoption and preparation of projects are not same with the high quality project-based learning. The project –based learning aims to solve a particular real problem related to science. The strategy itself drag the learners to prepare specific questioning, give multiple solutions, analyze scientifically the given solutions, enhance ability to reach a meaningful solution and ultimately adopt the best one for future.

  • Construction of concepts:

            Science teaching is not just the explanation of scientific causes behind any fact. The teacher should give conceptual lessons by arranging the inter-related concepts of entire   curriculum of a particular class. The science teacher facilitates the learners to build their own knowledge by attaining different concepts pertaining to the specific knowledge.

  • Organization of team activity:

            Innovative strategies are the successful outcomes of team work or activities. The co-operation among the team members give birth of an innovative thinking. The team comprises of both science teachers and students of the concerned level. Each and every individual are responsible to the team. Exchange of views, co-operation, giving suggestion between the team members ultimately facilitate implication innovative strategies in science teaching.

  • Emphasize on creative thinking:

            To bring out the innovative potentialities of the learners the science teachers themselves express their innovative thoughts through different activities such as transaction of lessons, giving assignments to learners, organize some memory games, applying laboratory methods etc. The entire atmosphere compels the learners to think innovatively.

  • Reflection of lessons:

            Imparting of science teaching is not confined to only achieving good academic score in science. Effective teaching of science develops scientific attitude and aptitude in learners. The lessons of science would be assimilated so deeply that will show their reflection in daily usual activities in and out of class room.

  • Recognition of discovery:

            To maintain and think of innovative ideas, activities, projects in science, the science teachers should always give recognition to new discovery. By doing so, it will reinforce the learners interested to new discoveries.

  • Preparation of science models:

            It is a constructive arena to explore the understanding of the real world. Actually it is a very significant and effective way to bring out the inner innovative potentialities of learners. By engaging in model preparation, learners get a scope to apply their acquired scientific knowledge, mensuration ability, imagination and creativity. It is a very cost effective approach. The science teachers are always there in every steps of preparation of scientific models.

  • Fishbone technique:

            It is such a technique which gives emphasis on cause-effect relationship to explain the scientific cause behind any events. The present technique helps to develop innovative thinking of learners in a sustainable manner. By using this technique, science teachers motivate creativity and boost up problem-solving abilities of learners.

  • Use of ICT and software application:

            Information communication technology has become the essential part of our regular lives. It has included in classroom also. In science classrooms science teachers can use programmed instructions and computer aided instructions; not only instructions but also use the electronic gadgets for presentations of teaching learning material, and measurement of the learning outcomes of students. Nowadays the new generation learners are getting more interested in different online modes. Some popular application software for innovative strategies of science teaching are Human body, Cosmic zoom, Video science, Science 360 etc.

  • Organization of science quiz and science exhibition:

            Science quiz is an interesting episode of classroom teaching of science. After completion of one or more than one chapter of science the science teacher can conduct science quiz by dividing the students in different groups. Here the students get opportunity to readily share their understanding of science topic with others.

            Science exhibitions are usually organized at school level by both the science teachers and students. Sometimes more than one school participate in the science exhibition. By organizing science exhibition students can get scope to utilize their innovations and also channelize themselves to science oriented activities from the very beginning of their lives.

            Here in the present discussion the emphasis is mostly given on innovative strategies of science teaching at school level by teacher education program in order to acquire all those skills by the future science teachers.

  • Membership of science club:

            The science teacher must be a member of local science club. Sometimes schools also form their own science club. In school science club, the science teacher and students both are the members. The science clubs are the right place where all members can share their scientific knowledge and also explore new arena of science learning.

  • Participation in science magazine publication:

            By providing articles based on science the student can participate in science magazine creation. The magazine provides the news of new scientific discoveries around the world. By doing this the student participants can update themselves. The science teacher supervises the overall activities and give their valuable suggestions to wall up the magazine successfully.

  • Set up of virtual science laboratory:

            It is an artificial set up of science laboratory where the interactions of learners create a situation of conducting simulated experiments. The students can easily get ideas about the inner and outer structures of anything related to science. The virtual laboratory is very useful for school level learners. Science teacher should be aware of the uses of virtual laboratories. 

Conclusion

            In this entire discussion the emphasis is mostly given on innovative strategies of science teaching at school levels. As the teacher education program provides the grooming sessions to acquire all these skills for the future science teachers, hence the above discussion is very relevant for science teachers and students in the teaching and learning of science subjects.          

RISK OF COVID 19 VICTIM FROM BIO-MEDICAL WASTE

What if corona virus is itself a by-product of Bio-medical waste..!!!

            Today the entire human civilization is facing the dominance of the expanded tentacles of COVID 19 disease. It is a global emergency for the human race. All the countries in every corner of the world are trying to combat with the situation by adopting various mechanisms. Its infectious capability is much more higher than its lethal power. Due to its high penetration rate in human population; WHO earmarked its effect a pandemic.

            The disease is spreading from one infectious person to others in an exponential rate. The study says that one person can infect 2.2 uninfected persons. It is really dangerous for thickly populated countries like India. If it breaks out; the control over the health service would have been a pathetic scenario due to its wide spread among high density population.  Actually countries are adopting any one of the two or both strategies to tackle the pandemic. The first one is to enhance the health service facilities by providing sufficient number of health units, beds, ventilations, test kits along with health workers like doctors, nurses with adequate supply of resources like personal protective equipment (PPE). Second one is forceful imposition of self-isolation and maintaining social distancing.

            Possible threat comes not only from infected person; but also from the Bio- medical wastes contaminated with the virus. Bio-medical waste is generated from biological and medical sources and activities, such as the diagnosis, prevention, or treatment of diseases. Common generators (or producers) of biomedical wastes include COVID treating hospitals, medical research laboratories, offices of physicians taking samples, morgues or funeral homes. Bio-medical wastes from those settings may pose an injury and exposure risks via occupational contact with medical waste for doctors, nurses and janitorial, laundry and refuse workers. So  all personnel  who are associated with such facilities  are at high risk of the disease. As it is clear to us the more and more health care facilities mean more generation of Bio-medical wastes. So whatever precautions for its proper disposal are to be taken to be known to those personnel associated very well.

Now, the focus will be given on the sectors which are to be victimized by bio-medica wastes of COVID 19.

  • RISK AT COVID 19 ISOLATION WARD

            In this ward THE COVID19 patients are admitted for treatment. The chance of getting infection is very high in this zone. The persons who are appointed to these wards should follow the guidelines of proper handling of Bio-medical as implemented by the Expert Committee viz.- separate colored bin/bag or container are to used, always use double layer bags for collecting waste from COVID 19 isolation wards etc.. The sanitizer workers should store the container separately and labelled the collection bin as “COVID 19”. Precautions should be taken while removing and disposing them off. Record should be kept on bio-medical waste of COVID 19.

  • RISK AT TESTING CENTRE FOR COVID 19

            Generally testing centres are the sample testing centres or laboratories for COVID 19 suspected patients under specific SPCBs. If any COVID 19 positive case has been found, then risk of infection is also there. In this sector, same type of precautionary measures are taken for handling, disposal and storage of the bio-medical wastes as followed in Isolation wards.

  • RISK AT HOME CARE/QUARANTINE CAMP FOR COVID 19 SUSPECTED

            This zone is created for COVID 19 suspected persons. The suspected are staying at either home quarantine or quarantine camps. Until any positive patient is not found, there is no risk. Still proper precautions and safety measures must be taken from the very first day of quarantine both by the  quarantined people as well as  quarantine camp staffs. In this unit the generation of biomedical waste is of less amount. Any bio-medical wastes are generated from home or quarantine camp should be collected in yellow bags/bins and handed over to the waste collector of CBWTF engaged by local bodies. Record should be kept.

  • RISK AT COMMON BIO MEDICAL WASTE TREATEMENT FACILITY (CBWTF)

            The persons who are engaged as CBWTF waste collector are really at high risk of infections. They are collecting the wastes from isolation ward, testing centres, individual houses, quarantine camps. They need regular sanitization facility and adequate amount of PPE involving three layered mask, splash proof aprons, nitrile gloves and gum boots and safety goggles.

            Everybody who are engaged in this tedious job of bio-medical waste management must follow the guidelines while handling, collecting and disposing the waste materials. Always the bio-medical waste should be collected separately from other solid waste and properly labelled as “COVID 19”. Ultimately the bags/bins should be handed over to only CBMWRF authorized collectors. Proper records should be maintain at every point of operation.

            On March 18th, Central Pollution Control Board released a set of guidelines regarding handling, collecting, treatment and disposal of bio-medical wastes generated during treatment, diagnosis and quarantine of COVID19 patients. Every persons must follow the guidelines. Otherwise we can’t check the spreading of COVID 19 from bio medical wastes. The concerned must look the matter seriously to minimize the number of COVID 19 victims.
