This study investigated the effects of several elements of instruction (objectives, in,ormation, practice, examples and review) when they were combined in a systematic manner. College students enrolled in a computer literacy course used one of six different versions of a computer-based lesson delivered on the web to learn about input, processing, storage(More)
Ethylene production and signalling play an important role in somatic embryogenesis, especially for species that are recalcitrant in in vitro culture. The AP2/ERF superfamily has been identified and classified in Hevea brasiliensis. This superfamily includes the ERFs involved in response to ethylene. The relative transcript abundance of ethylene biosynthesis(More)
Mobile technology opens the door for a new kind of learning called here and now learning that occurs when learners have access to information anytime and anywhere to perform authentic activities in the context of their learning. The purpose of this study was to investigate the effects of here and now mobile learning on student achievement and attitude. The(More)
Hevea brasiliensis is the main commercial source of natural rubber. Reactive oxygen species (ROS) scavenging systems are involved in various biotic and abiotic stresses. Genetic engineering was undertaken to study the strengthening of plant defences by antioxidants. To that end, Hevea transgenic plant lines over-expressing a Hevea brasiliensis cytosolic(More)
Executive Summary The use of computers has become pervasive and essential in today's world. Most of the universities offer a basic computer literacy course to the students. To meet the demand of computer-literate graduates, it is important to determine what constitutes a desired computer literacy course and how they should be taught. Formative evaluation of(More)
Ring-hydroxylating dioxygenases (RHDs) catalyze the initial oxidation step of a range of aromatic hydrocarbons including polycyclic aromatic hydrocarbons (PAHs). As such, they play a key role in the bacterial degradation of these pollutants in soil. Several polymerase chain reaction (PCR)-based methods have been implemented to assess the diversity of RHDs(More)
Instructional elements remain the foundation of current instructional design practice. Practice is the instructional element provided after learners have been given information required to master an objective and Navigation is the non-instructional element guides the learner on the sequence of instruction. Linear Navigation can be referred to as program(More)
Studying morphological changes of subcortical structures often predicate neurodevelopmental and neurodegenerative diseases, such as Alzheimer's disease and schizophrenia. Hence, methods for quantifying morphological variations in the brain anatomy, including groupwise shape analyses, are becoming increasingly important for studying neurological disorders.(More)
