This study was conducted in order to examine the process by which teachers designed a website. For this purpose, www.weebly.com, which is used as a website building tool, was selected and teachers were given tasks for web designing. Experiments were designed differently for experiment and control groups. Before performing the tasks, an introduction video was shown to the experiment group. Then, interview questions about the contribution of introduction videos and usability of website were asked. According to the results, the group that watched the introduction video completed the tasks in a shorter time than the group who did not watch the videos. At the same time, the group who watched introduction videos before using the site was able to complete more tasks than the group that did not watch the videos. These results show that the use of introduction videos as a navigation facilitator enhances the usability.Keywords: Website design experience, teacher education, usability, eye tracking.*

Writing Practice

Abstract This preliminary research is as a part of learning need analysis for developing a discourse based writing material with a timed-writing technique in an English teacher education department in Indonesia. In timed writing practice (TWP), students must write a paragraph on a sheet of paper without help in a given time limit. However, no empirical information on whether the students agree or disagree with the application of timed writing and the reasons behind their perceptions is not yet avaiable.The research subjects consist of 31 students who take writing course. The objectives are to investigate (1) the extent of the students’ acceptance and (2) the reasons behind the acceptance on the application of timed-writing practice (TWP) in writing class. A qualitative analysis is administered by identifying and classifying contents of students’ opinions and reflections expressed in the students’ responses to questionare. Twenty five students (81%) agree with the application of TW. Four students (13%) disagree and 2 students (6%) give no preference. Timed writing are perceived as (1) Encouraging Writing Activity,  (2) Improving Time Management and Control, (3) Training Thinking Skills, (4) Improving Writing Skills, (5)Training Speed Writing, (6) Improving Soft Skills, (7) Giving Challenging Activity, and (8) Improving Concentration and Accuracy.  The reasons from those who disagree are: (1) Feeling nervous and confused (2) Having insufficient preparation time, and (3) Expecting Variation of Activity. In conclusion, timed writing is mostly accepted and positively perceived by the students with very high category. Reasons from those who disagree must also be taken into consideration for future betterment. Based on the research findings, the timed writing, accordingly, can be used as a technique or a strategy to be integrated in a discourse-based writing material for students of English teacher education program.Key Words: Timed-Writing, Students’ Acceptance, Reasons

Denne studien er gjennomført på bakgrunn av et målrettet samarbeid mellom to videregående skoler og en lærerutdanningsinstitusjon med en målsetting om å styrke og utvikle en bedre sammenheng mellom praksisopplæring, pedagogikk og didaktikk. I teksten retter vi oppmerksomheten mot veiledning som et framtredende element i samarbeidet mellom de tre institusjonene. Vi støtter oss hovedsakelig til sentral teori om veiledning (Lauvås & Handal, 2014), teori som dreier om utvikling av det tredje rom (Zeichner, 2010) og om koherens i lærerutdanning (Raaen, 2014). Det metodologiske grep er deltakende aksjonsforskning, og datainnsamlingsmetoden som er tatt i bruk benevnes som brevmetoden (Berg, 2003). I artikkelen viser vi til og drøfter funn som tyder på at ganske ulike tilnærminger til måter å veilede på, kan bidra til læring og utvikling, og at praksislærers veiledningsfaglige kompetanse er avgjørende for kvaliteten på veiledningsøktene. Videre tyder funnene på at lærerstudenter ikke setter pris på monologisk og kontrollfiksert veiledning. Funnene avdekker også at praksislærere ser det som en naturlig del av sitt ansvar å veilede studenter inn i lærerprofesjonen. Både studenter og praksislærere gir uttrykk for at de opplever trepartsamtalen som særdeles verdifull og læringsfremmende, samtidig som tid og ressurser i veiledningen oppleves som kritiske suksessfaktorer.   This study has been carried out based on a targeted collaboration between two upper secondary schools and a teacher education institution. The goal is to develop a more coherent teacher education. In this article we focus on mentoring, because we consider it to be a crucial factor for making the collaborative quality between the three institutions better, as well as increasing the students’ learning outcomes of their practicums. We rely mainly on central theory about mentoring (Lauvås & Handal, 2014), theory concerning the development of ‘the third space’ (Zeichner, 2010) and coherence in teacher education (Raaen, 2014). The methodological approach is participatory action research, and the letter method is used to collect data (Berg, 2003). Findings show that rather different mentoring approaches can contribute to learning and development, and that the quality of the mentoring sessions depends highly on the mentors’ competence. Furthermore, we find that students do not appreciate monologue and control-oriented mentoring. The findings also show that the school mentors consider guiding the students into the teacher profession as an obvious part their work-obligation. Both students and mentors agree upon that the three angled conversation between the student, the practicum teacher and the mentor from the teacher training institution is particularly valuable and learning-promoting, while enough time and resources are considered to be crucial for success.

And Control

Electric fields have been applied across oxides growing on a high temperature alloy and control of the oxidation of the material has been demonstrated. At present, three-fold increases in the oxidation rate have been measured in accelerating fields and the oxidation process has been completely stopped in a retarding field.The experiments have been conducted with an iron-base alloy, Pe 25Cr 5A1 0.1Y, although, in principle, any alloy capable of forming an adherent aluminum oxide layer during oxidation can be used. A specimen is polished and oxidized to produce a thin, uniform insulating layer on one surface. Three platinum electrodes are sputtered on the oxide surface and the specimen is reoxidized.

The majority of blood vessels in the superior cervical ganglion possess a continuous endothelium with tight junctions. These same features have been associated with the blood brain barrier of the central nervous system and peripheral nerves. These vessels may perform a barrier function between the capillary circulation and the superior cervical ganglion. The permeability of the blood vessels in the superior cervical ganglion of the rat was tested by intravenous injection of horseradish peroxidase (HRP). Three experimental groups of four animals each were given intravenous HRP (Sigma Type II) in a dosage of.08 to.15 mg/gm body weight in.5 ml of.85% saline. The animals were sacrificed at five, ten or 15 minutes following administration of the tracer. Superior cervical ganglia were quickly removed and fixed by immersion in 2.5% glutaraldehyde in Sorenson's.1M phosphate buffer, pH 7.4. Three control animals received,5ml of saline without HRP. These were sacrificed on the same time schedule. Tissues from experimental and control animals were reacted for peroxidase activity and then processed for routine transmission electron microscopy.

And Control

It is well known that the rat adrenal zona glomerulosa steroidogenic activity is controlled by the renin-angiotensin system. The ultrastructural changes in the rat zona glomerulosa cells induced by renovascular hypertension were described previously, but as far as we are aware no correlated biochemical and morphometric investigations were performed.Twenty adult male albino rats were divided into 2 experimental groups. One group was subjected to restriction of blood flow to the left kidney by the application of a silver clip about the left renal artery. The other group was sham-operated and served as a control. Renovascular hypertension developed in about 10 days: sistolic blood pressure averaged 165 ± 6. 4 mmHg, whereas it was about 110 ± 3. 8 mmHg in the control animals. The hypertensive and control rats were sacrificed 20 days after the operation. The blood was collected and plasma renin activity was determined by radioimmunological methods. The aldosterone concentration was radioimmunologically assayed both in the plasma and in the homogenate of the left capsular adrenal gland.

Soft Radiation

Scanning electron beam lithography has been used for a number of years to write submicrometer linewidth patterns in radiation sensitive films (resist films) on substrates. On semi-infinite substrates, electron backscattering severely limits the exposure latitude and control of cross-sectional profile for patterns having fundamental spatial frequencies below about 4000 Å(l),Recently, STEM'S have been used to write patterns with linewidths below 100 Å. To avoid the detrimental effects of electron backscattering however, the substrates had to be carbon foils about 100 Å thick (2,3). X-ray lithography using the very soft radiation in the range 10 - 50 Å avoids the problem of backscattering and thus permits one to replicate on semi-infinite substrates patterns with linewidths of the order of 1000 Å and less, and in addition provides means for controlling cross-sectional profiles. X-radiation in the range 4-10 Å on the other hand is appropriate for replicating patterns in the linewidth range above about 3000 Å, and thus is most appropriate for microelectronic applications (4 - 6).

Spontaneous Delivery

Previous research has revealed that passive (involuntary inhalation) tobacco smoking during gestation can have adverse effects upon the developing fetus. These prior investigations did not concentrate on changes in fetal morphology. This study was undertaken to delineate fetal neural abnormalities at the ultrastructural level in mice pups exposed in utero to passive maternal smoking.Pregnant study animals, housed in a special chamber, were subjected to cigarette smoke daily from conception until delivery. Blood tests for determination of carbon monoxide levels were run at 15-18 days gestation. Sciatic nerve tissue from experimental and control animals were obtained following spontaneous delivery and fixed in 2.5% gluteraldehyde in 0.1M cacodylate buffer pH 7.3. The samples were post-fixed in osmium ferrocyanide (1:1 mixture of 1.5% aqueous OSO4 and 2.5% K4 Fe(CN)6). Following dehydration, the tissues were infiltrated with and embedded in Spurr. Sections were stained with uranyl acetate and lead citrate.
