A non-equivalent pre-test and post-test quasi-experimental design was employed. Two intact classes from different schools were randomly selected and assigned to experimental (n=38) and comparison group (n=45). From the previous semester, students’ record book revealed that both groups have almost an equivalent mathematics performance. A one-way ANOVA and paired sample t-test were used to analyze the data. Moreover, to check the equivalence of the groups, the same pre-test was developed and administered. The result indicates that both groups were equivalent. The test covers tenth-grade topics relations and functions, polynomial functions, exponential functions, and logarithmic functions. The study shows that students instructed through the blended learning approach surpassed those taught via the conventional method in their comprehension of mathematical concepts. The one-way ANOVA statistical result revealed there is a notable disparity between groups with effect size of η2 =.269, which is a large effect size. Moreover, a paired sample t-test shows the experimental group showed a substantial mean difference of 14.327 with a very large effect size (d=1.016) when compared with the comparison group. Thus, the study shows that blended learning was more effective in improving mathematical conceptual understanding when compared with a conventional method of teaching. Based on the findings, the researcher recommends blended learning in mathematics education and suggests stakeholders and policymakers incorporate the model into the curriculum.</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">585-599</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Majda   Fiksl</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">THE DEVELOPMENT AND MEASUREMENT OF THE EFFICIENCY OF MODERN DIDACTICAL MODELS IN THE TECHNICAL EDUCATION</style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">educational model</style></keyword><keyword><style  face="normal" font="default" size="100%">lesson factors</style></keyword><keyword><style  face="normal" font="default" size="100%">lifetime learning</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year><pub-dates><date><style  face="normal" font="default" size="100%">October/2012</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2014/457-1413727957.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">46</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Presented research shown a sensible inclusion of intelligent didactical environments in the practical work in the education of the technical field in Primary School. The teacher with his modest repertoire of hours dedicated to technical education confronts great challenges, like how to inspire the students for the subject with the introduction of many different interesting themes. Firm example of study lesson is based on theoretical foundations of Didactical learning theory, advanced version also named The Berlin model. During the process of teaching we transform knowledge into practical work and through a concrete example, designed a new modern didactical model. In this model the competences of a lifelong learning are included: methods for encouraging the motivation, use of ICT and developing informational literacy, encouragement of flexibility and persistence at confrontation with new challenges and exercises, ability to self evaluation, developing of communication and social skills. The results of experimental group, which execute activities in form of new didactical model in comparison with control group shown, that students of experimental group had less faults at making the model and they also spend less time to finish it. Consequential students of experimental group were much more satisfied with their product, they gained knowledge and they were also motivated for further work.</style></abstract><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">43-51</style></section></record></records></xml>
