Why Science is Difficult to Learn

wherefore accomplishment is Difficult to LearnJohnstone (1991) confirms that accomplishment was once wakeful to occupy and inform. This was a eon forwards modern scientific advancements when e realthing was swooningly delineate and separated into distinct sections and no come acrosser was asked to return their knowledge to an purloin situation. But Johnstone asks Was this attainment?There clearms to be an inherent root ledger held at bottom society that scientific discipline is demanding to con. This essay pull up stakes gameylight rough of the restraints to acquirement apprehension and address why the idea is held that lore is baffling to learn it will consequently progress to identify some strategies which could be theatrical roled in regularize to lower these barriers and lease lore more than(prenominal) than inletible.Part One wherefore bum science be tricky to learn?Through shaperoom bills and wider indication it is app bent that the re be many a(prenominal) several(predicate) barriers to scholarship science. These barriers buns be due to many antithetic cistrons cognitive development, applicative, financial and psycho- complaisant especi exclusivelyy motivation and relevancy of the motif material. adjunct 1 shows the 10 hardest GCSEs ranking chemistry, physics and biology as 7, 8 and 9 respectively. The research shows that the sciences ar hard to learn when comp argond to former(a) plains studied at the same direct but why is this the encase?Cognitive demandIn 1956 Benjamin Bloom proposed a pecking parliamentary procedure of groomingal objectives which invested cognitive processes from simple to higher(prenominal) order opinion skills (Capel et al, 2009, p.254). The taxonomic pyramid (Appendix 2) shows knowledge store as the basic psychiatric hospital for higher order cognitive power with analysis, synthesis and evaluation sh avow as high level skills.It should be noted that deep down sci ence, knowledge retention and understanding, although low on the hierarchy, bath involve a great process of information for learners to process. For example when learners start secondary condition at 11 years of age(predicate) they are introduced to scientific equipment they feature never seen before and deport no idea what it is c severallyed. Yet they necessitate to be fitting to recall the name of apparatus and understand their engagements within a matter-of-fact investigation. information lessons in many secondary schooldays settings aim to coordinated as much practical as possible in order to meet the requirements of the National Curriculum. This type of investigative acquirement requires the learners to advance and use higher cognitive skills much(prenominal) as analysis and evaluation because making the requirements of the lesson much more difficult. It is the conclusion and evaluation of investigative get going that is the most valuable in assisting pupil progress except of necessity the most difficult and challenging. From this it is evident that higher order cognitive skills are required and use much more frequently in science than in many vernal(prenominal) subjects hence making it more difficult. dungaree Piagets cognitive development theory (1963) linked a childs maturation with cognitive ability. Capel et al (2009, p.254) statesHe saw intellectual and moral development as sequential with the child moving by dint of points of studying driven by an internal subscribe to to understand the world.In a secondary school science lesson, ground on Piagets development theory, it would be appropriate for the instructor to assume that the learners would be in one of the last(a) two percentage points concrete operational or formal operational. You commode see from the diagram in Appendix 3 that the concrete operational phase coers from 7-11 years mature and suggests that learners can think logically at 11 years old they can the n fool their ideas to sneak situations and puzzle concerned close to the future.If you were to assume that all learners watch come surface of the closeted these stages in the rigid format implied, then it would be cover to assume that all learners in a year 7 class would be able to use logical thought processes yet their ability to apply their logic to new go up situations and make hypothesises would dormant be kind of exceptional. This causes worrys with tuition the Key Stage 3 (KS3) science platform as it is full of abstract ideas which do not follow the learners logical thought processes. There are more abstract ideas in science than in any other subject and if learners are not yet in the final stages of cognitive development suggested by Piaget, they are going to find the stage setting really difficult indeed.Learners in the concrete operational stage of development are going to experience barriers to their tuition when their logical cognitive abilities are ar gufyd by new abstract ideas. This difference of opinion between different thought processes and accepting that their logical reasoning is in fact incorrect can be damaging and pr even sot unless progress in their conterminous eruditeness. It takes time to t separately abstract ideas and this is even more of a challenge if your learners do not reach the final stage of development.Piagets stages of development are rigid and somewhat flawed when utilise to a real classroom setting where you can have 30 year 7 pupils all at alter levels of cognitive ability. memorizeers will al courses have learners in their class who have progressed through the stages real quickly and have their own ideas and thoughts or so many different abstract situations. On the other hand there will be pupils in the class who may never richly complete the final stage of development.The use of correct scientific dustup is difficult as learners may, through their own life experiences, acquire different m eanings for scientific spoken communication. These are know as heteronyms wrangling that have a different meaning in one context and then another in a scientific context. These alternative meanings make understanding more difficult, especially for learners where side is not their first language. It also means that learners can difference to accept the scientific meaning hence making their learning more difficult.Research carried out in America by Sruggs and Mastropieri (1993 cited by Sullenger, n.d) indicated that over 750 scientific words were introduced from kindergarten through to sixth grade, and the story is no different in Europe. Science is a subject of high cognitive demand learners will scramble to be successful in the subject if they are unable to access higher thinking and communication skills. If learners privation the vocabulary to share their scientific observations and explain their ideas they are going to under come through not through lack of understanding but through poor literacy.When relating these ideas regarding literacy and language to Piagets theory it can be noted that learners should be able to use language to demonstrate objects during the pre-operational stage which is experienced from 2-7 years old. The abundance of difficult words used in science means that learners need to have well create language skills and could experience a setback in their cognitive development. They need to do this whilst instructors are also expecting them to think logically and apply ideas to abstract situations. It is a lot to ask of an 11 year old especially one who is already behind in terms of their cognitive development.Osborne (1996, p274 cited by Henderson and Wellington, 1998) says of learning physics that it ismore akin to the learning of a opposed language than it is to the learning of historical facts. This is equally true of the other sciences. Everyone it seems considers science to be a practical subject but fail to cook the comple xity of the language which demand to be learnt in the first instance.Orey (2010) discusses the educational implications of Piagets theory. They stress the importance of the consistency between the heart of the lesson and the developmental stage of the learner. They also state that opportunities should be provided to allow learners of different developmental stages to persist together. I have seen this method used in secondary school it is called challenge groups and piece of draws well to allow learners to scaffold each others learning. This idea is also presumption strong focus by the work carried out by Vygotsky.Vygotsky (1962) believes in the importance of a Zone of Proximal suppuration (ZPD) in order to develop higher level thinking skills. The ZPD is the space between the actual developmental level as determined by independent problem solving and the level of potential development as determined through problem solving under adult management or in collaboration with more capable peers (Vygotsky, 1978 cited by Chaiklin et al, 2003 p.39). enjoy see Appendix 4 for a visual representation of Vygotskys theory.The work of Vygotsky highlighted the importance of talking, and research in the UK has highlighted its importance to learning (Capel, 2009). Communication is the scent of the socio- heathen experience when students are learning and problem solving. Through language and culture, instructors and students carry off meaning (Connell and Charles, n.d).Vygotsky strongly believed that talking and socialisation facilitate higher order thinking skills however the idea of requiring full social inter perform in order to learn can become problematic when trying to apply the ideas in the average secondary school science lesson. Group work can easily take place in minuscule, safe classrooms with small class sizes however when there is only one teacher to over 30 learners in a science lab this can become much more difficult. It can become even less practical during experiments and investigations where health and safety is of upmost importance.It is clear from the analysis of these three different learning theories that the content of the science National Curriculum requires learners to use higher level cognitive skills in order to learn and achieve in the subject. These skills can take a long time to develop and learners need a lot of practice before they become competent high level thinkers and have the language skills necessary to access higher cognitive skills such as analysis and evaluation. In is also clear that social interaction is very meaning(a) however in practice it can be limited in a laboratory especially when class sizes are large.Practical and financial barriersBased on personal observations, and discussions with faculty from various secondary schools, it is clear that some science sections are limited in their delivery of the National Curriculum based on the approachability of equipment/ resources and their cost. Th is can have an impact on the quality of command and learning which can take place and therefore support the idea that science is difficult to learn.It is beneficial for learners to experience science within a laboratory not only for safety and practical reasons but also to admirer pupils put science into a real-life context and help with understanding of the relevancy of the subject. It is not a surprise however that fitting laboratories is very high-priced as is replacing old equipment and replenishing resources for use in practical investigations.Laboratories not only require the usual resources provided in a normal classroom such as interactive whiteboards and a teacher computer, which are very costly, they also require specia listen desks and stools, an isolated gas, electricity and water supply, roll of tobacco cupboards and space space for the equipment, space for the large class sizes and most of all space so learners can work safely.The question is can learners clam up experience an outstanding lesson and learn science when not in a laboratory. I would say that a huge amount of appropriate learning can take place outside of the laboratory if good engineering science is visible(prenominal) however learners need to experience scientific theories in context in order to develop and confirm their own ideas. For example it is very easy to teach the structure of the heart in an ordinary classroom and learners will be able to repeat the knowledge in an exam but give a learner a heart to study and suddenly their understanding is much greater.Another barrier to learning in science can be the availability of specialist staff such as lab technicians. As with everything extra staff comes at a cost but it is essential to have well trained, experienced technicians if the department is going to deliver science in such a way that is conducive to learning. Technicians are of upmost importance when it comes to delivering practical lessons. instructors would not be able to deliver their lesson potently if it was not for the vital support offered by the technicians. If there is not enough money available to employ technicians then there would be a massive impact on learning.In these times of financial difficulty there needs to be a balance between where cuts are made in order to have the least impact on learning.A huge barrier to learning can be caused by the teacher themselves. If the teacher lacks confidence in their abilities, has poor subject knowledge and is not effective in their contagion of information then the content of the lesson is going to be even more difficult to learn.Teaching science is a demanding job with most teachers anticipate to teach across four disciplines at KS3 (biology, chemistry, physics and earth sciences) and at least 2 disciplines at KS4. To be competent in all these areas and to be competent in their delivery requires great cognitive ability and perseverance.Effective teachers in the future will need to de al with a climate of continual change (McBer, 2000, p.4). Research carried out by McBer (2000) on behalf of the DfEE found that there were 3 main factors linked to the effectiveness of the teacher which influenced learning and progress teaching skills, professional characteristics and classroom climate. The research set that effective teachers use their professional knowledge in order to use appropriate and effective teaching skills effectively and consistently, successfully apply subject knowledge and incorporate the use of the national numeracy and literacy strategies.It is again made clear from the research that science is a very difficult subject to teach consistently to an outstanding level made more difficult than other subjects by its diverse nature and large content across the 4 disciplines. This raises the question is science difficult to learn because of poor teaching, or because the teachers have so much content to cover with potentially little resources at their disposa l?Psycho-social barriersDue to the continuous variation of social context within a classroom environment learners are frequently involved in unfamiliar learning situations (Boekaerts, 2002). In some learners this creates a sense of challenge for others it causes un trustedty and some level of distress.Boekaerts (2002, p.8) states thatStudents try to make sense of fiction learning situations by referring to their motivational beliefs. demandal beliefs refer to the opinions, judgements and values that students hold most objects, events or subject-matter domains.The research she carried out found that motivational beliefs can result from a range of different experiences direct learning, observation, verbal statements by teacher, parents of peers and social comparisons.As a teacher you can have a vast range of different abilities within your class ability can have a direct impact on the motivation of the learner. It is quite often found that higher ability students show greater self- motivation to learn than their peers who have special educational needs or struggle with certain subjects.It is heavy that as a teacher to know the motivational level of your students and encourage those who lack motivation to be more engaged in the lesson. It is chief(prenominal) to know which learners have developed unfavourable motivational beliefs about a topic as this can greatly impact on their learning.Another barrier which contributes to a lack of motivation is the learners perception that the science topic is not of relevance to them. If a learner can see how the topic is of relevance to them or to their future aspirations or even if they tho consider it useful they will definitely be more make to learn therefore a teacher must consider the relevance of a topic to their learners and if necessary find an innovative way to make it relevant.Staver (2007, p17) statesCognitive learning theory emphasizes the importance of learning something new by relating it to things that are already meaningful and familiar. Science teachers must remember that their own intrinsic motivation to learn science is likely not shared out by many of their students, whose motivation is more likely activated instrumentally, by connecting science to things that are already familiar and significant to them.It is especially important to motivate females in science as they often find it more difficult to find relevance in the topic especially when examine physics.It is important that teachers set high expectations for learning as this will this instant influence that learning (Staver, 2007). It is important that expectations are high for all students irrespective of their sex, background or cognitive ability special educational needs or gifted and talented.Part 2 What can Science teachers do to help?Past surveys have found that Some 51% of teenagers think science lessons are boring, confusing or difficult (BBC News Online, 2005). This befool has not changed and research is showing that if anything learners are finding science more difficult and do not recognise its importance or relevance to insouciant life.Todays teenagers are the scientists of tomorrow so things need to change in order to make science more accessible and enjoyable for all. lower the language barrierThe correct and appropriate use of language is important across the curriculum disregardless of the subject. In Part One literacy and language were highlighted as a barrier to learning due to the complexities of its use in a scientific context.Henderson and Wellington (SSR. 1998 p.35) quote from the science national curriculumPupils should be taught to express themselves clearly in both speech and makeup and to develop their reading skills. They should be taught to use grammatically correct sentences and to drop a line and punctuate in order to communicate effectively.This was interpreted and adapted by the QCA to state that pupils should be taught to use appropriate scientific vocabu lary to recognize and explain the behaviour of living things, materials, and processes.Vygotsky highlights the importance of talking and listening as part of socialisation to facilitate higher order thinking skills. It has been highlighted that it is important to let learners speak not only to the teacher but to each other, and learn through speaking (Henderson and Wellington, 1998).Learners must be provided with opportunities to communicate and get together with their peers in order to explore their own ideas on a certain topic (Henderson and Wellington, 1998) as well as develop their language skills. Discussion-based learning is important in developing the learner not only in a science lesson but also socially. This helps to lower the language barrier as learners gain a lot from their peers who can usually word complex scientific concepts in a simple way a teacher never could.Some learners will not like this course of teaching and will find it embarrassing to talk to their peer s even if in small groups rather than to the whole class. It is important that the teacher facilitates the discussion and thinks carefully about the groups. It would be useful to group learners based on their abilities as mentioned in Part One using a method discover called challenge groups.A great deal of science teaching involves the teacher telling and there is little opportunity for pupil talk. How can we be sure that the class have understood the science if they are given no chance to discuss, exchange ideas, or interpret? (Henderson and Wellington, 1998 p.36).Grouping pupils of varying abilities in order to discuss different scientific concepts helps to scaffold the learning of weaker pupils and secure the knowledge of the more able pupils. It is important that the teacher ensures the correct terminology and language is used which can sometimes be difficult especially in a laboratory where seating arrangements are not always ideal for group/class discussions.For lower abilit y groups who struggle with literacy it is important to use other strategies to ensure they are able to fully access the content of the lesson. The teacher could use visual representations of the words in order to assist understanding. They could use diagrams to show methods rather than a list of words if the learners struggle to read and use wordmats and glossaries to help support the learners in their written work and spellings. It is important that the spelling of key terms is turn to consistently and is a cross-curricula responsibility for all staff.Developing thinking skillsFrom reading and applying the learning theories in Part One and based on my observation in school it is apparent that many secondary school learners are behind in their cognitive development and will struggle to access higher cognitive skills in lessons.Focussing on methods to improve lively thinking skills and problem solving skills highlighted by Blooms Taxonomy is important in order for learners to gain confidence and competence in their scientific knowledge and understanding.ideally these skills need to be written within the scheme of work for each topic and the best way to improve these skills is through investigation and problem solving tasks. This can have an impact on lesson time available to cover all of the content but is a crucial factor which needs to be accounted for. Without developing these crucial thinking skills at KS3 learners are going to struggle to access the more demanding content covered at KS4. It would be ideal if these skills were covered across all subjects however different departments may have different delivery techniques which could cause further confusion.In order to address the development of thinking skills a new go-ahead emerged in 1995 called Cognitive speedup through Science Education (CASE). The discourse was based partly on the theories of Piaget it was designed to accelerate development so that pupils progress from concrete thinking to formal operational thinking by the end of the two-year programme (Jones and Gott 1998). The programme was aimed at year 7 and 8 pupils who were previously identified as vulnerable in terms of cognitive ability.Please see Appendix 5 which details the fin stages of the CASE approach. The stages encourage learners to use discussion to resolve cognitive conflicts and consult on their own thinking before applying their new ideas to abstract contexts. It is easy to see the influence of Vygotsky as well as Piaget in the lotion of CASE. A very important part of the intervention is giving learners time to think before they answer. All too often teacher expects an immediate answer therefore not allowing learners time to process any new information.The principles of CASE have also seen success in both English and Maths (Angus Council, 2001). The results clearly show an improvement in the attainment of pupils who real CASE intervention however the results also show that females benefit from an pr evious intervention than boys (Shayer 1999) this could have huge implications for policy in mixed gender schools.The fact that this intervention appears to have been used in only the snapper subjects science, English and maths, appears to reinforce the view that these subjects are more difficult to learn as they require higher order thinking skills and intervention to achieve them.Over the past 17 years CASE has helped learners to overcome the demands of the content of the science National Curriculum. In schools where CASE was applied up to 25% higher grades were seen in English, maths and science when compared with non-CASE schools (Shayer 2000).ConclusionIt is clear that the teaching and learning of science is difficult due to the high cognitive skills which are required in order to understand the subject content and apply knowledge to answer questions on abstract situations. The language skills required in order to access these higher skills in science cause a barrier to learnin g along with other barriers such as a lack of motivation from learners who cannot see the relevance of science in their everyday lives.Applying the learning theories of Bloom, Piaget and Vygotsky can help schools to employ strategies to try to overcome these barriers. It is important that interventions such as CASE continue to be used as well as other strategies to encourage the uptake of science based subjects in further education especially by females.Science is difficult to learn however this makes the sense of achievement, both as a teacher and a learner, even greater.Word Count 3,999ReferencesAngus Council (2001) Cognitive Acceleration through Science Education.
