The in vitro cultivation of human cells is an essential part of the work of every diagnostic cytoge-netics laboratory. Almost all human cytogenetic studies involve the examination of dividing bloodcell population by blocking cell division at metaphase with subsequent processing and staining bybanding techniques. The chromosome constitution is described as Karyotype that states the totalnumber of chromosomes and the sex chromosome constitution. Karyotypes are prepared by cuttingup a photograph of the spread metaphase chromosomes, matching up homologous chromosomes andsticking them back down on a card or nowadays more often by getting an image analysis computerto do the job. Chromosomes are identied by their size, centromere position and banding pattern.Teaching a student how to detect and interpret even the most common chromosome abnormaliti-es is a major challenge: mainly, in a developing country where the laboratorial facilities are notalways available for a big number of students. Therefore, in this work we present an educationalsoftware for teaching undergraduate students of Medical and Life Sciences Courses how to arrangenormal and abnormal chromosomes in the form of karyotype. The user, using drag-and-drop, is da-red to match up homologous chromosome. For that, we have developed a free full access web site(http://www.biomol.net/cariotipo/) for hosting the software. The latter has proved to be light andfast even under slow dial-up connections. This web site also oers a theoretical introductory sectionwith basic concepts about karyotype. Up to now the software has been successfully applied to un-dergraduate courses at the University of Rio de Janeiro (UNIRIO). The students have approved thesoftware; to them the similarities with the well-known game solitaire turns the exercise more excitingand provides additional stimulus to learn and understand karyotype. Professors have also used thesoftware as complementary material in their regular classes. Based on their testimonies the softwarewas a helpful tool for explaining the karyotype assembly.

<p class="apa">The study examined ‘Students’ Involvement in Social Networking and attitudes towards its Integration into Teaching. The study was carried out in the University of Uyo, Akwa Ibom State, Nigeria. The population of the study consisted of 17,618 undergraduate students enrolled into full time degree programmes in the University of Uyo for 2014/2015 academic session. The design of the study was survey design with ex-post facto approach. Random sampling technique was used to select 1730 students from the 12 faculties in the University. The instrument used for the study was ‘Students’ Social Networking and Attitude Questionnaire which was validated by an expert in curriculum studies and an expert in measurement and evaluation in the University of Uyo. Cronbach’s Alpha Statistical method was used to determine the reliability coefficient of .70 for the instrument. Two research questions and two null hypotheses tested at .05 level of significance guided the study. Mean and Standard Deviation were used to answer research questions; Independent t-test and Analysis of Variance were used to test the hypotheses. The results show that there is significant difference in involvement of university undergraduate students in Social Networking based on course of study, level (year) of study and age. Female undergraduate students’ involvement in social networking is higher than that of their male counterparts; but male undergraduate students showed a higher positive attitude towards integration of social networking into teaching and learning.</p>

Theoretical and practical classes were offered in the university labs of Universidade Federal Fronteira Sul –UFFS (Chapecó, Santa Catarina State, Brazil) in order to promote the contact of students and teachers of public schools with the university. In this context, it was possible to put the students in contact with procedures, equipments scientific and teaching practices in the areas of Biological Sciences. These activities aimed at improving learning and stimulating the students from the schools in which were part of the academic and scientific community, and as a result, to promote the interaction between university and public schools. Fifteen student groups took part in the project, which totaled around 320 students who had lessons on microscopy, cells and tissues, blood typing and biological decomposition of organic food. This project encouraged students that had a previous contact with the world of science to enter university. In addition, the teachers who accompanied the students were encouraged to continue being creative in their classes. For the undergraduate students involved, the project enabled personal growth and encouraged them to develop skills beyond what they were taught in the classroom.

Remote Learning

In Spring 2020, due to the rapid spread of COVID-19, all educational institutions in Latvia, including the University of Latvia (UL), transitioned from face-to-face on-site learning to remote learning. After a short period of face-to-face on-site learning in autumn, UL returned to remote learning in November for the second time. This paper investigates the UL students’ perspectives on remote teaching and learning at the UL during the first and second COVID-19 periods. The research assesses several remote study organization aspects, including the lecturer’s and student’s digital skills, their access to information and support during the study process, planning and implementation of the study process, and students’ acquisition of the content. The study used an original questionnaire designed in the Spring 2020 semester. Seven questions from the first questionnaire were included in another follow-up questionnaire distributed in the Spring 2021 semester. A total of 2248 UL students from the Spring 2020 semester and 742 students from the Spring 2021 semester participated in the study, representing 13 faculties across all study levels. The survey responses were collected via a QuestionPro survey platform and then downloaded into an IBM SPSS 28 file for a reliability check. Next, descriptive statistical analyses were conducted for each reported survey item using Microsoft Excel 2016. The research presented here implies that, in general, students perceive positive improvements in almost all the investigated aspects of the organization of the remote study process when comparing the first and second COVID-19 periods, which could indicate a certain level of resilience in students and university lecturers when subject to COVID circumstances. However, the results reveal that students have, in one year, developed a more realistic approach in assessing their digital skills. The results lead us to believe that remote on-line learning is not just a short-term solution but could become a valuable element for providing qualitative education in the long term. It could indicate that the students and lecturers at university are ready for new and sustainable higher education study organization solutions in the future.

The present study is based on a chapter of the PhD project conducted by the main researcher. It aims to explore the ESL teaching and learning practices in a Pakistani university by focusing on difficulties perceived and confronted by learners and teachers, and solutions suggested by them. One of the most significant issues at the university is large classes-exceeding to 100 and more students on average. The main researcher, being an ESL teacher at the target university, faced the same problem of large size and found it difficult to teach these classes. He embarked on analysing the situation so that he might come across some solutions through the suggestions and experiences of the ESL teachers and students of the same university. The design of the study is descriptive and the results of the present study come from the quantitative data collected through student and teacher questionnaires. The Student-participants were 300 undergraduate students from various major subjects attending English language support classes and 22 ESL teachers teaching these English language support classes at different institutes of the university. The data were analysed descriptively and presented with help of the boxplots. The views, commonly held by teachers are supported by the study&rsquo;s findings i.e., large classes are likely to endorse teacher-centred approaches of teaching; very little significant student-student and teacher-student interaction is practised because of the inadequate physical environment; majority of learners remain off-task and appear to be unruly and they are given little, if any, feedback on their in-class and home tasks. Conversely, many teachers and learners reported that the adoption of group/pair work is likely to be an effective technique to use in these classes. Albeit a few teachers revealed having adopted group work infrequently, none used it all the time.

Qualitative data were collected from observation of students' activities when working on blogs in the classroom, analyses of students' blog documents on the web, and interviews with 42 students. Most students reflected that blogs are user friendly and convenient tools for publishing and sharing studies. Moreover, blog implementations contributed positively to students' information searching and writing skills, despite the limited opportunities that many students had for Internet access outside the university. However, students' ignorance regarding copyright issues and their tendency to copy information from online sources and paste it into their blogs was a common problem.</span>

An interactive computer-assisted learning (CAD program, which simulates experiments performed on segments of rat colon (in vitro) to study the pharmacology of intestinal motility, is described. The program covers: a) the actions of drugs that affect cholinergic excitatory neurotransmission in the colon; b) the effects of sympathomimetic amines; and c) an investigation of the mechanism of action of the laxative, phenolphthalein. The program can be run on any IBM-compatible PC, and makes use of text and high-resolution graphics to provide a background to the experiments and to describe the methodology. The screen display emulates a chart recorder, and simulated results, derived from actual data, are presented, in response to student selection of pre-determined experimental protocols from a menu. The program is aimed at undergraduate students, and is intended to support or replace a conventional laboratory practical class, while achieving the majority of the same teaching and learning objectives.
