Practical work in science has several purposes including: practicing skills, developing specific knowledge and understanding of science, and developing an understanding of the processes of scientific enquiry. It has the potential to contribute to meaningful learning in science (SCORE) (2008). However, the present study was considered a number of factors that influencing practical works in chemistry in secondary schools a case of Wolaita zone, Ethiopia. Key factors among them are teachers’ poor knowledge of practical work, full timetable of chemistry teacher for the theoretical classes, absenteeism of the teacher at practical classes, late commencement of teaching practical class; lack of awareness and motivation from school managements and unsafe working environments, lack of separate chemistry laboratory, lack of equipment in the laboratory, number of students larger than the …show more content…
However, on the outcome of this study, it can be concluded that: teachers-related factors that influencing practical work in chemistry are teachers’ poor knowledge of practical work, fulltime table of chemistry teachers for the theoretical classes, absenteeism of the teacher at practical classes, late commencement of teaching practical class; lack of awareness and motivation from school managements and worrying working environments due to lack of waste disposal policy and regulation in the schools. Laboratory-related factors are lack of separate chemistry laboratory, lack of equipment in the laboratory and too short period allocated for practical work. And also law attitude students’ toward practical work in chemistry. Moreover, the roles of ICT within practical work in chemistry are unquestionable. Indeed, the result revealed a low level of expectation that developments of ICT would improve practical work in science is influencing practical work in
Biochemistry is the study of the chemistry that takes place in living organisms, especially the structure and function of their chemical components, such as proteins, carbohydrates, lipids, nucleus acids, and small molecules present in cells. Biochemistry can be classified into 4 major categories carbohydrates, lipids, proteins and amino acid, and nucleic acids. There are so many jobs available in the field of biochemistry for example hospitals, universities, agriculture, food institute, education, cosmetics, forensic crime research, drug discovery and development. Biochemists provide new ideas and experiments to help us better understand how life works, support our
On December 19th 2007, a small chemical manufacturer T2 Laboratories suffered a catastrophic failure and release while in production of a compound that is produced to increase octane in gasoline and is a common additive in fuel production Methyleclopentadienyl manganese tricarbonyl or MCMT. The failure occurred during production and resulted in the death of 4 and injuries to 32 people, 28 of which were members of the community. (CSB, 2009)
The Nobel Prize is a set of annual international awards bestowed in a number of categories by Swedish and Norwegian committees in recognition of academic, cultural and scientific advances. Chemistry is one of the many categories of Nobel Prizes awarded to chemists that have dedicated life changing research in their perspective fields. In 2013, the Nobel Prize in chemistry was awarded to three theoretical chemists, Michael Levitt, Martin Karplus, and Arieh Warshe, who developed a multiscale computer to predict complex chemical reactions

The educational process is multi dimensional for student teachers and then study materials, but since technology has come in our lives, it has become the last that completes the education process.
Almost everyone attends a school at one time in their life whether the classroom includes technology or not. Research shows that technology isn’t used as often as one might think. The article, “High Access and Low use of technology in High School Classrooms” illustrates the use of technology by stating that only one in ten of elementary and middle school teachers are daily users of computers (Cuban, Kirkpatrick, Peck). Most schools now have classrooms that use technology throughout the entire class time and even at home to do homework. Although some people might agree with the use of technology in class, it is more harmful to the students than useful. It can cause many distractions, it can be difficult to use and can take away from learning time.
The researchers appeared to have the knowledge and skill to conduct the research. Two research professors from the University of Florida who specialize in educational science research conducted the study, published in the journal Research in Science Education. Contact information was also provided fo...
In classrooms today, educators are constantly seeking and implementing engaging lessons that will increase student knowledge and skills. The intent of the activities is to help students become independent learners and use process thinking skills. Students seem to learn best by actually directing their own learning and doing, rather than being led from step to step by the teacher. In science, it is especially important that students learn by inquiry and use more of a hands-on approach to learning scientific concepts. According to Wilke and Straits (2005), inquiry-based learning is where students explore a problem using the processes and tools of the discipline. It is often shown in a way that resembles the scientific method (Wilke & Straits, 2005). The scientific inquiry model demonstrates four phases that involve students in identifying a problem and investigation using inquiry-based learning (Joyce, Weil & Calhoun, 2009). The four phases suggests that students are introduced to an area of investigation, then they develop a problem, next the problem is identified in the investigation and finally students come up with ways to solve the problem (Joyce, Weil & Calhoun, 2009). Science education is part of everyday life being that the skills learned in science, such as, the scientific method are used in solving problems that occur daily. Dalton, Morocco, Tivnan, & Mead, 1997 found that students seem to learn best by actually doing science, such as asking questions, designing experiments, observing, predicting, manipulating materials, and learning from their own mistakes. I believe the scientific inquiry model exemplifies an excellent way to implement inquiry-based learning by using the scientific method in any classroom; es...

Photographs can convey meaning more quickly than reading words. Two photos on the final page of this report illustrate the importance of education. The first picture shows students working with a teacher in a science class. The students show the initiative to come forth and do experiments with the teacher and are willing to take in the knowledge to help with ...
Technology is also used as a tool in the method of teaching and learning for faster and easier education. It is now an academic necessity i...
Technology forms the most vital element of life in the world today. Every aspect of our lives is dominated by technology and its importance in our lives is indispensable. One of the outstanding facts about technology use in schools is its controversial nature. There is no common agreement by stakeholders in technology and educations sectors about the use of technology in schools. There are two different factions, one supporting use of technology as a positive aspect, while the other faction disagrees, citing the detrimental effects of technology in students. However, the use of technology in classrooms catering for children continues to increase, as education develops more interesting ways of enhan...
Though many people fail to realize it, chemistry is a subject essential to everyday life, due to the fact that it is the branch of science that deals with the identification of the substances of which matter is composed. But what we must understand is that everything in the universe is composed of matter, hence chemistry is necessary in learning more about the world and universe that we live in. There are many careers and fields affiliated with chemistry that people pursue to learn more about the composition of the universe, but for now, let us examine the logistics of three of these careers. These three careers involving chemistry are geochemistry, environmental chemistry, and chemical engineering.
They also need this relationship to be able to plan their lesson effectively. For children, understanding the nature and process of science is dependent upon their developmental level and the experiences teachers provide for them. Children can begin to understand what science is, who does science, and how scientists work through classroom activities, stories about scientists, and class discussions. Teachers should provide children with many opportunities to make observations with all their senses, to look for patterns in what they observe, and to share with others what they did and what they learnt from their
One of the widest used methods is learning through discovery. Discovery is finding out information using hands on experiments. The children can discover what happens in science and why. They answer the problems for themselves. They use their schema, prior knowledge of science, to search for information. The cycle of scientific discovery is first a question or series of questions are raised. Second, through a discussion a problem is identified and narrowed so that the kids can solve the problem. Third, with the assistance of the teacher, the children propose a way of looking at the problem and then collect the...
