Hellen Mutundu a county SMASE INSET trainer conducts a biology session on development of manipulative,observatory and recording skills in learners at Isiolo boys ,Isiolo county.She is now cascading training to other teachers of biology who shall apply the skills in their classes.This is the cascade system of INSET as used in the SMASE program.
The INSET participants are teachers with a teaching experience of between 1-6 years.The discussion were quite informative.They found the discussion on identifying scientific concepts from the content most informative.They Recognised and appreciated the importance of creating learning situations to aid students to understand the concepts.It is evidence of deeper learning.

Jubilee Government is committed to introducing ICT integration Education starting from Primary level and CEMASTEA has a big role to play in this noble goal. This is in recognition of the critical function of ICT integration in education as one of the 21st Century skills. It is also in conformity with Sessional paper No. 14 of 2012 which recognizes ICT as a major vehicle in teaching and learning process. CEMASTEA thus is conducting training on ICT integration in INSET activities in different counties. This is has been an ongoing process since last year, 2014. The training includes 50-100 participants with a blend of ICT champions, District Trainers, teachers for science, languages, technical, humanity subjects and other stakeholders. The duration of the training is one week and counties are expected to cascade the training to the rest of teachers and other officers.

The following is the teachers schedule to be used for the month of March and April.

CEMASTEA is partnering with the International Business Machines (IBM) to implement the Teachers TryScience (TTS) Programme. The aim of the programme is to capacity-build teachers by providing resources to strengthen instruction and better prepare students for the 21st Century jobs; many of which will be increasingly in STEM. The 3rd Cohort workshop whose theme was “Deepening Understanding of ICT Integration Using TTS Materials was held at CEMASTEA on 17-18 February 2015. The workshop brought together 60 mathematics and science teachers from 30 schools spread across six counties namely Kisumu, Kwale, Nyandarua, Samburu, Taita-Taveta, and Vihiga. It was opened by Mr. Stephen Njoroge, Director CEMASTEA and closed by Ms. Mildred Otsieno; IBM’s Corporate Citizenship & Corporate Affairs Manager, Marketing & Communications for East Africa.

The objective of the workshop was to:

  • Strengthen teachers’ ICT skills and,
  • Assess suitability of the TTS content for Kenyan curriculum and national goals.

The workshop also promoted national integration and cohesion by providing an opportunity for teachers across six counties to interact and create friendship. Key areas covered included:

  • 21st Century Skills and Approaches
  • Project Based Learning
  • Understanding Science, Technology, Engineering and Mathematics (STEM) Approach through TTS

CEMASTEA has variety of innovations and in this demonstration, a national trainer is explaining to students how a Pinhole camera operates.

A pinhole camera is a simple camera without a lens and with a single small aperture, a pinhole – effectively a light-proof box with a small hole in one side. Light from a scene passes through this single point and projects an inverted image on the opposite side of the box.

A pinhole has the ability to function like a glass lens because it excludes all light rays which are not reflecting off the subject that the camera is pointed at.  When light hits an object, it is scattered in all directions; this is why the object is visible from any angle.  If all this light was entering a camera and hitting the film, no image would be produced.  The light needed for a photo has to be aligned to make a focused image.  The pinhole excludes light rays from all irrelevant angles and only allows through rays which are almost perfectly aligned from the subject through the pinhole to the film. 


For example the above image show a clear explanation on how the inversion occurs. The yellow lines are light rays.  Note that they cross at the pinhole and produce an inverted image. In our case, the arrow will be viewed as inverted, that is, arrow facing up.
