An interactive computer-assisted learning program is described, which simulates a number of experiments which can be performed on the isolated, innervated duodenum of the rabbit (the Finkleman preparation). This preparation is one of the classical pharmacological preparations used to demonstrate to undergraduate students the effects of selected drugs: those acting on adrenoceptors or intestinal smooth muscle, or those affecting responses to sympathetic nerve stimulation. The program runs 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. A screen display which emulates a chart recorder presents simulated results (spontaneous or evoked contractions of the gut), derived from actual data, in response to the selection by students of predetermined experimental protocols from a menu. The program is designed to enhance or replace the traditional laboratory-based practical using this preparation, whilst achieving the majority of the same teaching and learning objectives.

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.

Four papers by Clint Denison and Imogen Custance, Louis Lafleur, James Rogers, and Andrew Obermeier will be presented at the Eighth Annual JALT Vocabulary SIG Symposium in Tokyo, Japan, on September 20, 2020. The topics covered in the four papers are vocabulary learning using online student-created vocabulary lists, development of a flashcard program that manipulates the review schedule and question format, creation of a list of multi-word units based on corpora, and examination of the acquisition of declarative and tacit vocabulary knowledge from deliberate computer-assisted learning. This commentary briefly summarizes each study and offers suggestions for future research. All of the four studies exhibit how computer technology can be used to facilitate vocabulary research, teaching, and learning.

The main advances in education and the current expansion of training models are due to the incorporation of information and communication technologies (ICTs), as well as pedagogical elements arising from the socio-cultural approach. Communication is an essential element in the processes of teaching and learning in this educational approach. Therefore, ICTs offer us an excellent innovative support, allowing use to make use of such virtual learning environments as Collaborative Computer-Assisted Learning (CSCL), which enables communication, mediation and knowledge construction. Virtual communication is one of the essential elements in blended learning, and it is even starting to play an important role in traditional teaching environments. In this regard, we consider that a contribution from different teaching and learning experiences in virtual scenarios (Synergeia; BSCW; Moodle…) is necessary. In this article, we describe several cooperative and collaborative computer-mediated learning experiences with students of different educational levels. The results and conclusions on Collaborative Computer-Assisted Learning experiences reveal an improvement in motivation, academic performance and the development of social and communication skills, regardless of the use of cooperative (cooperative learning techniques) or collaborative learning. Los principales avances educativos y el actual auge de los modelos de formación se deben a la incorporación de las tecnologías de la información y la comunicación, así como a la aplicación de elementos pedagógicos provenientes de aproximación sociocultural. Desde este enfoque educativo, la comunicación es un elemento esencial en los procesos de aprendizaje y enseñanza, por tanto, estas herramientas, entendidas como artefactos tecnológicos de producción cultural, ofrecen un excelente soporte innovador, permitiendo contar con entornos virtuales de aprendizaje, como las ofrecidas por las plataformas para el aprendizaje colaborativo mediado por ordenador (CSCL) que favorecen la comunicación, la mediación y la construcción compartida del conocimiento (coconstrucción). La comunicación virtual es uno de los aspectos esenciales en la formación a distancia como también lo es la formación semipresencial (blended learning), que comienza a adquirir un importante papel en contextos presenciales que utilizan estos entornos como instancias complementarias destinadas a extender la clase fuera de las fronteras del aula. En este sentido, es relevante un aporte de las diversas experiencias telemáticas de aprendizaje que usan modalidades de aprendizaje cooperativo o colaborativo en entornos virtuales. En el trabajo que presentamos se organizan y describen experiencias de aprendizaje cooperativo y colaborativo mediado por ordenador con estudiantes de diferentes niveles educativos. Los resultados y conclusiones de dichas experiencias evidencian una mejora de habilidades sociales, habilidades comunicativas, motivación y rendimiento académico independientemente del tipo de modalidad de aprendizaje compartido.

The Corona Virus Disease 19 (COVID-19) pandemic has imposed serious restrictions for academic institutions to maintain their research and teaching practical subjects. Universities have implemented adaptive measures to maintain educational activities and achieve the learning objectives for undergraduate and postgraduate students by shifting to online teaching and learning. Although such approaches have enabled delivering the theoretical content of courses during the pandemic, universities have faced serious difficulties in running practicals with actual research experiments and teaching hand-on skills because such activities potentially override the required safety guidelines. Here, we report an adaptive measure, implemented at Monash University, to run home-based studies in cognitive neuroscience and achieve learning objectives, which are normally delivered in face-to-face practicals. We introduce two specifically designed short-term research projects and describe how different aspects of these projects, such as tutorials, experiments, and assessments, were modified to meet the required social distancing. The results of cognitive tests were closely comparable between the laboratory-based and home-based experiments indicating that students followed the guidelines and the required procedures for a reliable data collection. Our assessments of students’ performance and feedback indicate that the majority of our educational goals were achieved, while all safety guidelines and distancing requirements were also met.

This study examined the effects of Computer Assisted Learning (CAL) on the mastery of Science concepts by learners in universities. Teaching and learning of Science concepts present learners with numerous challenges. Of critical concern is the negative perception by learners that Science based subjects are difficult, thus contributing to widespread poor performance by the learners in the national examinations and subsequently poor choice of the subject in the universities. Solomon Four Group experimental design was employed for the study. The target population comprised all first-year students taking science subjects in 8 universities in western Kenya. A sample size of 335 students was determined using Krejcie Morgan table (1970). The universities were divided into two forming experimental and control groups.  The study was carried out in 4 months spanning 16 weeks where pretest was administered after the first 8 weeks of conventional teaching and post-test administered after the next 8 weeks of treatment. Pretest and post-test Science Achievements Test (SAT) on two topics, digestive system and light and optics, were designed and administered by the respective lecturers, and scores recorded. Piloting was carried before the use of the instruments, and a reliability coefficient of 0.85 on SAT was recorded.  Data were analyzed using t-test one-way ANOVA. The study found that 171 students taught using CAL achieved significantly higher scores in SAT compared to164 students taught through conventional methods with a mean gain of 2.851. The study demonstrated that CAL enhanced active manipulation of content and promoted interaction with content, and gave reality to abstraction. The study may be significant to educationists, lecturers, researchers, and policy makers as it provides insight on the benefits of applying Computer Assisted Learning in Science Education.
