Technology Education About Life Science

Karl Kjer Shared his experience. In Mav 2000, Matthew Meselson, an issue related to biological weapons, leading figure in the life sciences on issues related to biological weapons, offered a warning at the annual meeting of the U.S. National Academy of Sciences. Every major technology-metallurgy, explosives, aviation, electronics, nuclear energy has been internal combustion, intensively exploited, not only for peaceful purposes but also with biotechnology, certain to for hostile ones. Must this also be a dominant technology of the next century? During the century just modify fundamental life processes continues its rap in, as our ability to aid advance, we will ways to destroy life but will also be able to manipulate it including the processes of cognition, development, reproduction, and inheritance. A world in which these capabilities are widely employed for hostile purposes would be a world in which the very nature of conflict has radically changed.

Therein could lie unprecedented opportunities for violence, coercion, repression, or subjugation. Concerns about the potential security risks posed by life sciences research can be seen in the context of rising concerns and sometimes ty sharp disagreements about the more general risks of weapons of mass destruction (WMD), including biological weapons and bioterrorism, following the end of the Cold War (see, for example, Carter, Deutch, and Zelikov 1998). More specifically, a number of articles in scientific journals early in this decade sparked controversy about whether the risks cited by Meselson were already present, with critics charging that the publications could provide a "blueprint" or "roadmap" for nations or terrorists.?

Karl Kjer Yet even work with the greatest seeming potential for misuse most often also offers significant potential benefits, and judgments about the implications of research were seldom simple or definitive. Box 1-1 contains examples of some of the contentious articles; in every case the reality and extent of the risk were vigorously debated. The possibilities and attendant uncertainties-regarding whether and how advances in the life sciences intended for legitimate and beneficent purposes might also be used for malevolent ends has come to be called the "dual use dilemma", a term that is the subject of considerable debate. For the purposes of the workshop, Professor Michael Imperiale, a member of the NRC organizing committee and the U.S. National Science Advisory Board for Biosecurity (NSABB) (see below), presented and discussed definitions of several key concepts as an aid to common understandings during the first plenary session.


Dual Use Research: In the life sciences, dual use refers to the possible beneficial or malevolent use of reagents, organisms, technologies, or information. Learning things is not limited to the scentific area. Instead it also has relations with some other things like speaking a language or using software, including Rosetta Stone Japanese and Rosetta Stone Korean. If you have a creative mind, you will make all your own differences in the end!

Teacher Education and Teacher Quality

Karl Kjer say's One of the sectors which fosters national development is education by ensuring the development of a functional human resource. The institution of strong educational structures leads to a society populated by enlightened people, who can cause positive economic progress and social transformation. A Positive social transformation and its associated economic growth are achieved as the people apply the skills they learned while they were in school. The acquisition of these skills is facilitated by one individual we all 'teacher'. For this reason, nations seeking economic and social developments need not ignore teachers and their role in national development.

Teachers are the major factor that drives students' achievements in learning. The performance of teachers generally determines, not only, the quality of education, but the general performance of the students they train. The teachers themselves therefore ought to get the best of education, so they can in turn help train students in the best of ways. It is known, that the quality of teachers and quality teaching are some of the most important factors that shape the learning and social and academic growth of students. Quality training will ensure, to a large extent, teachers are of very high quality, so as to be able to properly manage classrooms and facilitate learning. That is why teacher quality is still a matter of concern, even, in countries where students consistently obtain high scores in international exams, such as Trends in Mathematics and Science Study (TIMSS). In such countries, teacher education of prime importance because of the potential it has to cause positive students' achievements.

The structure of teacher education keeps changing in almost all countries in response to the quest of producing teachers who understand the current needs of students or just the demand for teachers. The changes are attempts to ensure that quality teachers are produced and sometimes just to ensure that classrooms are not free of teachers. In the U.S.A, how to promote high quality teachers has been an issue of contention and, for the past decade or so, has been motivated, basically, through the methods prescribed by the No Child Left Behind Act (Accomplished California Teachers, 2015). Even in Japan and other Eastern countries where there are more teachers than needed, and structures have been instituted to ensure high quality teachers are produced and employed, issues relating to the teacher and teaching quality are still of concern (Ogawa, Fujii & Ikuo, 2013). Teacher education is therefore no joke anywhere. This article is in two parts. It first discusses Ghana's teacher education system and in the second part looks at some determinants of quality teaching.

2.0 TEACHER EDUCATION by karl Kjer

Ghana has been making deliberate attempts to produce quality teachers for her basic school classrooms. As Benneh (2006) indicated, Ghana's aim of teacher education is to provide a complete teacher education program through the provision of initial teacher training and in-service training programs, that will produce competent teachers, who will help improve the effectiveness of the teaching and learning that goes on in schools. The Initial teacher education program for Ghana's basic school teachers was offered in Colleges of Education (CoE) only, until quite recently when, University of Education, University of Cape Coast, Central University College and other tertiary institutions joined in. The most striking difference between the programs offered by the other tertiary institution is that while the Universities teach, examine and award certificates to their students, the Colleges of Education offer tuition while the University of Cape Coast, through the Institute of Education, examines and award certificates. The training programs offered by these institutions are attempts at providing many qualified teachers to teach in the schools. The National Accreditation Board accredits teacher training programs in order to ensure quality.

The National Accreditation Board accredits teacher education programs based on the structure and content of the courses proposed by the institution. Hence, the courses run by various institutions differ in content and structure. For example, the course content for the Institute of Education, University of Cape Coast is slightly different from the course structure and content of the Center for Continue Education, University of Cape Coast and none of these two programs matches that of the CoEs, though they all award Diploma in Basic Education (DBE) after three years of training. The DBE and the Four-year Untrained Teacher's Diploma in Basic Education (UTDBE) programs run by the CoEs are only similar, but not the same. The same can be said of the Two-year Post-Diploma in Basic Education, Four-year Bachelor's degree programs run by the University of Cape Coast, the University of Education, Winneba and the other Universities and University Colleges. In effect even though, same products attract same clients, the preparation of the products are done in different ways.

It is through these many programs that teachers are prepared for the basic schools - from nursery to senior high schools. Alternative pathways, or programs through which teachers are prepared are seen to be good in situations where there are shortages of teachers and more teachers ought to be trained within a very short time. A typical example is the UTDBE program, mentioned above, which design to equip non-professional teachers with professional skills. But this attempt to produce more teachers, because of shortage of teachers, has the tendency of comprising quality.

As noted by Xiaoxia, Heeju, Nicci and Stone (2010) the factors that contribute to the problems of teacher education and teacher retention are varied and complex, but one factor that teacher educators are concerned about is the alternative pathways through which teacher education occur. The prime aim of many of the pathways is to fast track teachers into the teaching profession. This short-changed the necessary teacher preparation that prospective teachers need before becoming classroom teachers. Those who favor alternative routes, like Teach for America (TFA), according to Xiaoxia, Heeju, Nicci and Stone (2010) have defended their alternative pathways by saying that even though the students are engaged in a short-period of pre-service training, the students are academically brilliant and so have the capacity to learn a lot in a short period. Others argue that in subjects like English, Science and mathematics where there are usually shortages of teachers, there must be a deliberate opening up of alternative pathways to good candidates who had done English, Mathematics and Science courses at the undergraduate level. None of these arguments in support of alternative pathways, hold for the alternative teacher education programs in Ghana, where the academically brilliant students shun teaching due to reasons I shall come to.

When the target is just to fill vacant classrooms, issues of quality teacher preparation is relegated to the background, somehow. Right at the selection stage, the alternative pathways ease the requirement for gaining entry into teacher education programs. When, for example, the second batch of UTDBE students were admitted, I can say with confidence that entry requirements into the CoEs were not adhered to. What was emphasized was that, the applicant must be a non-professional basic school teacher who has been engaged by the Ghana Education Service, and that the applicant holds a certificate above Basic Education Certificate Examination. The grades obtained did not matter. If this pathway had not been created, the CoEs would not have trained students who initially did not qualify to enroll in the regular DBE program. However, it leaves in its trail the debilitating effect compromised quality.

Even with regular DBE programs, I have realized, just recently I must say, that CoEs in, particular, are not attracting the candidates with very high grades. This as I have learnt now has a huge influence on both teacher quality and teacher effectiveness. The fact is, teacher education programs in Ghana are not regarded as prestigious programs and so applicants with high grades do not opt for education programs. And so the majority of applicants who apply for teacher education programs have, relatively, lower grades. When the entry requirement for CoEs' DBE program for 2016/2017 academic year was published, I noticed the minimum entry grades had been dropped from C6 to D8 for West African Senior Secondary School Examination candidates. This drop in standard could only be attributed to CoEs' attempt to attract more applicants. The universities too, lower their cut off point for education programs so as attract more candidates. The universities as alleged by Levine (2006) see their teacher education programs, so to say, as cash cows. Their desire to make money, force them to lower admission standards, like the CoEs have done, in order to increase their enrollments. The fact that, admission standards are internationally lowered in order to achieve a goal of increasing numbers. This weak recruitment practice or lowering of standards introduce a serious challenge to teacher education.

The Japanese have been able to make teacher education and teaching prestigious and therefor attract students with high grades. One may argue that in Japan, the supply of teachers far exceeds the demand and so authorities are not under any pressure to hire teachers. Their system won't suffer if they do all they can to select higher grade student into teacher education programs. To them, the issues relating to the selection of teachers are more important that the issues relating to recruitment. However, in western and African countries the issues relating to recruitment are prime. It is so because the demand for teachers far outweighs that of supply. Western and African countries have difficulties recruiting teachers because teachers and the teaching profession is not held in high esteem. Teacher education programs therefore do not attract students who have very good grades. It is worth noting that, it is not the recruiting procedure only that determines whether or not teacher education will be prestigious, however recruiting candidates with high grades, ensures that after training, teachers will exhibit the two characteristics essential to effective teaching - quality and effectiveness. Teacher education can be effective if the teaching profession is held in high esteem and therefore able to attract the best of applicants. Otherwise, irrespective of incentives put into place to attract applicants and irrespective of the measures that will be put in place to strengthen teacher education, teacher education programs cannot fully achieve its purpose.

In order to strengthen teacher preparation, there is the need for teacher preparation programs to provide good training during the initial teacher training stage, and provide and sustain support during the first few years after the teachers have been employed. That is why Lumpe (2007) supports the idea that pre-service teacher education programs should ensure teachers have gained a good understanding of effective teaching strategies. Methodology classes therefore should center on effective teaching strategies. Irrespective of the pathway the training program takes, the program must be structured such that trainees gain knowledge about pedagogy, besides the knowledge of subject matter. They should also get enough exposure to practical classroom experience like the on-campus and off-campus teaching practice. Whether or not there is the need to fill vacancies in the classroom due to the high teacher attrition, many countries face, teacher preparation programs should aim at producing quality and effective teacher and not just filling vacancies.

3.0 DETERMINANTS OF TEACHER QUALITY

Teacher quality has such enormous influence on students' learning. Anyone who has been in the teaching business will agree that teacher quality is central to education reform efforts. Priagula, Agam & Solmon (2007) described teacher quality as an important in-school factor that impact significantly on students' learning. Quality teachers have positive impact on the success of students. Where the students have quality and effective teachers the students make learning gains while those with ineffective teachers show declines. With respect to the classroom teacher, teacher quality is a continuous process of doing self-assessment so as to have professional development and a self-renewal, in order to enhance teaching. For the teacher educator, an effective or quality teacher is one who has a good subject-matter and pedagogy knowledge, which the he/she can build upon.

Outstanding teachers possess and exhibit many exemplary qualities. They have the skills, subject matter, and pedagogy to reach every child. They help equip their students with the knowledge and breadth of awareness to make sound and independent judgments. Three determinants of teacher quality will be considered here. They are; pedagogical knowledge, subject-matter content knowledge and experience.

Karl Kjer- Cleaning an Aquarium Is Now Easy To Do


Karl Kjer is a one of the famous science professor as well as researcher. In his free time he also likes fishing therefore he always provides best tips regarding fish aquariums. Here he provides tips for cleaning an aquarium.

Python No Spill Clean and Fill vacuum is now the talk of the town. Will having access to this product have a predictable impact on the fish tank? Will this technology improve the health of the fish? Will this product be used easily and effectively, given the normal understanding of its operation? The real answer to all the above questions is yes. There is not much doubt that among the most likely favorite vacuum for the aquarium is Python No Spill Clean and Fill, which have been in the market for more than a decade, put aside other expensive, non-efficient aquarium vacuums, and, in the process, got excellent customer reviews by being successful in its line of work, and sometimes extraordinarily so. Something about what this vacuum does and how they perform have some people come to count on it.

The flip side of Python No Spill Clean and Fill is that it can be attached to the faucet directly to vacuum your fish tank's gravel and suck the water out simultaneously, thus saving time. You don't have to wait until you are in over your head before knowing how to carefully operate without a mess. The ability to change out water without discoloration and smell while keeping the fish safe, that other filtration system cannot achieve, seems to be the major driving force for many customers who bought this product. The Python makes use of the water pressure from the faucet to create a siphon, drains the aquarium water quickly thereby creating a gravel vacuum. The suctioning of gravel is accompanied with directing the waste material to the sink drain and tumbling back the essential gravel into the tank. The on/off valve controls the movement of water in and out of the tank during gravel cleaning.

This vacuum product is also seen as a solution for aquariums that are located far away from the water connection. The Python has a twenty five foot hose that is FDA approved, adapters, a patented UV stabilizer system with tubing to prevent toxins from entering the fish tank, switch, hose connectors and faucet pump. With a 7 to 1 vacuum suction ratio, Python uses less water-about the same quantity used to flush an environment friendly toilet and the design prevents water from splashing or spilling.
It is possibly impossible to know exactly the benefits of Python No Spill Clean and Fill vacuum before you try it out. This is a great product both for novice and experienced fish tank owners. The amount of time and money you will spend browsing on the internet looking for the right fish tank vacuum is a key consideration in selecting the one. In other words, the choices you make in selecting the device when you are starting out can either help or hinder you down the road. Why spend too much on wrong technology you can't really use? After narrowing it down to one choice with less cost and more flexibility and capacity, for $35, there cannot be a better bargain than this.

Karl Kjer - Setting Up a New Fish Tank Aquarium


A fish tank aquarium can be a relaxing and welcome addition to any home. Below are a few considerations to take into account when setting up your first salt water aquarium.

Don't be misled by the thought that a smaller tank is better for beginners. The water conditions and temperature are much more stable in a larger tank. Any changes that would affect the fish will take place more slowly. Sudden variations in living conditions are stressful for the fish. A 25-30 gallon tank would probably be a good choice for your first tank.

Every couple of weeks you will need to clean the tank of algae and do water changes and water testing. The water temperature, PH, and salt content must all be monitored carefully. It is important to have your fish tank aquarium set up properly before adding the fish as salt-water fish are expensive and no one wants a tank full of dying fish.

One question you will naturally ask yourself is "How many fish will my tank hold?". A pretty good rule of thumb is one inch of fish for each 12 square inches of water surface area. It is not a good idea to push this maximum to the limit with a new tank. A more established tank could support more fish.
Lighting will be an issue for you to consider. A full spectrum florescent bulb offering a light spectrum similar to sunlight will be best for brightly colored fish and healthy plants. Light containing more purple wavelengths will bring out the color of tropical fish and light tending toward blue will produce more algae. Lights containing red or orange will facilitate the growth of aquatic plants.

A filter will be a must in your new fish tank aquarium to maintain healthy fish. There are three types of filtering available for your tank. They are mechanical, chemical, and biological.

Mechanical filtration gets rid of fish waste and solid particles that may be in the water. A typical mechanical filter would wok by pushing the water through a sponge, which would capture particles.
An activated carbon filter will provide chemical filtration and remove toxins from the water. It will also remove phosphates and ammonia from the water. Any filter should provide this feature.
Biological filters filter out toxins and decayed material through the action of friendly bacteria that are allowed to develop in the tank. This biological filtration resembles the conditions found in nature and is essential to a healthy tank.

There are many types of filters to choose from but incorporating the three types of filtration mentioned above will insure the quality of water in your tank.

Karl Kjer - Include World of Fishes in Your Home with Fish Tanks


Fish Tanks add new and colourful look to your home and it don't take much space in your house because it can accommodated anywhere in your home and also it is easily manageable. Fish tanks are not only for fishes, you can keep other marine mammals, turtle also. Usually fish tanks are made up of plastic or glass. You can choose any one of them. It is recommended to get filter inside fish tank as it prevent tank from become polluted and water from stagnate and because of this fish can survive for a long time. The size of fish tank depends upon size of fishes. If you have more fishes and spacious room then you can go for big one.

Karl Kjer

 

Before getting fish, first you have to buy fish tank to prepare it for fishes. As you buy Fish tank, clean it first with detergent and warm water and then let it dry thoroughly to ensure no traces of detergent is left behind because even a little detergent can harm your small and delegate fishes. Clean all other accessories like backing pictures, rocks, shells, aquatic plants and other decorative items also that you want to include in it. Make some places using rocks where your fishes can hide itself for a while. Floating plants should also be added after the tank s full. Gravel should also be rinsed well. Fish tank need some maintenance and you must clean and replace its water at least once in a month.

 Don't set up Fish tank in direct sunlight because algae can grow in it because of sunlight. Some equipment will need power so keep it near power outlet. Tank should be half filled with water and water that you are about to fill in it should be fresh, clean, de chlorinated and after filling water don't forget to check if is there any leaks. When you fill water again in it then pour it gently so as to give minimum disturbance to gravel. Your fish tank will require stand also that can bear the burden of aquarium and use a layer of polystyrene tiles between tank and stand.
an give you best fish tank, tank filters and other relative accessories for your fish tank.

Professor Roles & Expectations

 
The roles and expectations of professors at universities and colleges are nearly tied to the central function of advanced education. One of the initial formal descriptions of these central functions was incorporated in the 1915 "Declaration of Principles" defined by a representative council of the American Association of University Professors.
This declaration clearly defines that the functions of universities and colleges include:
  • To propel the sum of human knowledge and to promote request
  • To create experts for diverse branches of the public service
  • To give general guidelines to the students
Accordingly, the Karl Kjer professors at universities and colleges undertake teaching, research and service roles to achieve the academic work of their respective colleges. Generally the expectations and roles of a college professor are neither straightforward nor simple. A professor is recognized differently by the institute administration and by the students. Yet to become a successful professor, you must be capable to fascinate both groups. At times, this can be a frightening task. The role of a professor is simple for students- just to be an educator and instructor. This position demands that they must have complete knowledge about the subject they are going to teach and should be able to present knowledge in an interesting and cohesive manner.


 From a good educator, there is a clear expectation of themselves availing to their students and learners. If a student needs explanation of an important point and in case if it is not understood, the learning process at that time will virtually stop. Professors must provide assignments and exams that are related to the study material and that all assignments are sorted fairly, accurately and impartially. A professor acts as a mentor and a guide to the students. Karl Kjer say that the successful future of students or learners is partially dependent on the professor's way of teaching. This is really a wonderful responsibility. 

However, institute administrators consider professors from a completely another perspective. Because the process of education is desirable, it is not of predominant importance. They believe- the most important is that the Karl kjer professors must fulfill their contractual obligations to the institute. Although satisfaction of students is of concern to the administration but still it is not of utmost matter of concern. For them, academic standards are more important. And in the search of academic excellence, few students will fail and few will do poorly. As a professor, primary duty will be for students. But that doesn't mean that we lose sight of the fact that the administration is paying. That's why our initial loyalty must remain with our university or employer.
