  • GREEN BAY HIGH SCHOOL Science Department Memo To; Morag From John/Linda c.c John Date 7 December 2006 Re: The Science Curriculum and possible future directions. The second learning paradigm and implications for Science education or why is it necessary to programme lots of practical science into the learning process. This is a response to discussions during and after yesterday’s CMT meeting. It is an attempt to put some issues facing the department into context. Post Picot As with all initiatives that take hold in education the full consequences only become apparent with time. Senior course content has always been driven by existing assessment practices and it is no surprise that the shift to standards based assessment has impacted on curriculum delivery. The assessment of practical skills has been good for Science and our students perform well in practical situations. Internal assessment demands time in two ways: • Time is required to practice the skill or undertake field trips. • Time has to be allocated for reteaching and reassessment Recent programme changes in Science In 2006 we dropped the internally assessed Practical Investigation with Guidance and adopted the externally assessed Geology achievement standard. The change was a response to difficulties associated with class size and the poor state of the laboratories in B and D blocks. The new Science building has largely eliminated these problems. (The laboratory area is designed to allow practical work with class sizes of thirty and the classrooms have seating for 32.) Green Bay High School students need time to assimilate course material and the Education Revue Office in their penultimate visit recommended that we do less. The geology unit at year 10 covers most of the NCEA level 1 course. We decided that the Geology external would be useful to extend our more able students. Teaching would be restricted to about 4 weeks with the expectation that students would revise material from the fourth form course the fourth form and assimilate then extra content to meet level 1

  • The challenges include: Three hours a week allocation in the junior school. No one involved with junior curriculum delivery has completed all units of work. (Was 4 hours in year 10 at Marcellin) Adequate preparation of junior students for NCEA level 1 is difficult. The wide ability range in junior classes and class sizes can be a challenge. Structural differentiation (high impact on learning) through banding by blocking of junior classes in the timetable would be beneficial. Development of differentiated learning strategies within the classroom (lower impact on learning) is being looked at by the Department next year. Literacy initiatives with an ICT slant are being implemented within the department in 2007. This unfortunately exacerbates the “time to teach” problem. A shift Students should be given the opportunity to experience non linear learning in a Science context. We learn naturally in eclectic mode and our brains are programmed to make sense of a bewildering array of sensual inputs (Mark Treadwell). Students should experience science in a less structured way than they currently do in the limited practicals they are exposed to in the three hours per week of linear tuition. This could happen in year options in units of learning such as: • Chemistry of Art ( copper etching, glass making lithography and making oil paints • Biotechnology (yoghurt making, brewing bacteria and antibiotics) • Electronics (simple circuits, building a radio or amplifier tuner) We have enough the enough experience within the department to run these courses.

  • The importance of a new educational paradigm These questions are often asked about new technology, • What do smart boards actually do? • Are they just an expensive version of overhead projector technology • They cost an extra $2,000 over the cost of a projector. What will this technology offer that a projector and laptop doesn’t? • Is it cost effective? The answers are probably: • Ask me again in two years, I’m trialling their use and can’t answer this. • Yes but hmm but • Not much and hmm • Probably not. It would be impossible to gain funding for new technology based on these legitimate questions and uninspiring answers. The problem is that these questions and their answers relate to the existing learning paradigm, book based, which has been with us in a recognisable fom since the Middle Ages. If we ask the same questions of a new paradigm that recognises the importance of the internet and ICT. Does such a paradigm exist? The answer is no but this could challenge us to construct a new philosophy. A first stab at a new paradigm for education at any level might read. Students will learn in a seamless environment that encompasses their physical space and cyberspace. They can access an infinite source knowledge and information and ask deep learning questions. Obviously this is just a starter and will evolve. The questions we ask of this paradigm are somewhat different. What tools do we need to make this paradigm work? We need a portal that allows us to access the huge volume of knowledge and learning tools that are available. What would this portal look like; we have just invented a smart board. This underlines the importance of articulating a new paradigm. The paradigm has to underpin the technology and not the other way round.
