Abstract
The aim of this study was to evaluate the effect of coherent principlin multimedia learning environment. In doing so, the issue of the creation of lightening concept was represented via 4 different animation to junior students of secondary school (N=112). The first group observed the animation with the coherent concept, the second group watched the animation with seductive details with less interest (irrelevant details), the third group watched it with seductive details with more interest that led to emotional interest and the forth group watched the animation with seductive details with more interest that led to cognitive interest. Learning the process of lightening formation was evaluated via maintenance and transmission, the test of cognitive load was used for investigation of the amount of cognitive load of experience during training and response to question. For investigating the research hypotheses the one way ANOVA, contrast coefficient and follow test were used. Better performance of the fourth group in maintenance and transmission information compared with the third group indicates that the seductive details are not seductive always. On the other hand the better performance of the first group in one test of the information maintenance compared with the second and third group indicates the impact of coherent principle.

Abstract
Efforts to further progress in practice and learning have introduced cognitive imagery and action observation. The aim of this study was to investigate the effect of different practice ratios on consolidation the motor memory of girls with cognitive load. This research was a quasi-experimental study with a pretest, acquisition and retention design. The statistical population of the study includes primary school students in the 18th district of Tehran in the academic year of 97-98 who were selected by convenience sampling method. 98 elementary school girl students in the age range of 8-12 years were randomly divided into 10 groups (physical practice, motor imagery, action observation, motor imagery - physical practice and action observation - physical practice) based on inclusion criteria. Were. Demographic, motion imaging (MIQ-R) and motion imaging resolution (VMIQ-2) questionnaires, Strope task and serial color matching task were used to collect information. Participants made an effort in the 1920 acquisition phase and 48 hours later in an 80-block memorial session. To analyze the data, analysis of covariance test 2 (assessment steps: acquisition, retention) × 5 (experimental groups) with repetition on the factor of assessment steps, SPSS software was used. The results of analysis of variance showed that the main effect of practice type and cognitive load type was significant (p <0.05). The results of Bonferroni post hoc test showed that the participants in the practice observation and imaging group with low cognitive load had the best performance and the participants in the practice group with low cognitive load had the weakest performance compared to the other groups. Performing practice in a combination of observation and imaging will lead to better performance in learning and consolidation motor memory.

Abstract
Cognitive Load Theory is one of the most powerful research frameworks in educational research. The main concern within this framework is to develop a proper instrument to measure cognitive load. Hence, the goal of this research was to investigate the reliability and validity of the Cognitive Load Questionnaire designed by Kelpsch, Schmitz and Seufert (2017). This questionnaire was administered to 206 seventh- and eighth-grade female students, in which they rated the amount of intrinsic, germane, and extraneous load of various learning tasks on a 7-point Likert scale. The reliability and validity of the questionnaire were examined and confirmed through Cronbach's alpha coefficient and t-test in which the quality of individuals' answers in different tasks were compared together. In addition, confirmatory factor analysis was performed using LISREL 8.80, to investigate factor structure of the questionnaire. The results showed that the questionnaire has desirable reliability and validity to measure different types of cognitive load. The results of confirmatory factor analysis also revealed a three-factor structural model whose fit indices suggested a desirable fit with the data, thus corroborating the three-factor structure of the cognitive load questionnaire. Therefore, this questionnaire can be a proper measure to assess different types of cognitive load in seventh and eighth grade students.

Abstract
The present study was conducted with the aim of the effects of segmentation and redundancy methods on cognitive load and vocabulary learning and comprehension of English lessons in a multimedia learning environment.The purpose of this study is an applied research and a real experimental study. The statistical population of the present study includes all people aged 14 to 16 who are enrolled in language schools in Damghan. The subject of the educational content was to explain the activity of volcanoes in the form of PowerPoint software in a maximum of 10 slides (based on the type of group) to 90 subjects who were randomly divided into six groups (15 people in each group). High segmentation / Audio presentation, High segmentation / Visual presentation, High segmentation / Redundant, Low segmentation / Audio presentation, Low segmentation / Visual presentation, Low segmentation / Redundant were assigned. The research was completely experimental (a completely random 2×3 factor design). Researcher-made test of vocabulary and comprehension learning, prior knowledge assessment and Pass Cognitive Load Scale (1992) were used to collect data. Analysis of variance was used to analyze the data.The results of analysis of variance showed that the interaction between segmentation method and redundancy method on cognitive load and learning was significant. The results of post hoc test also showed that the High segmentation / Visual presentation group reported significantly lower cognitive load and higher vocabulary and comprehension compared to other groups. According to the obtained results, it can be said that segmentation and redundancy methods are effective in reducing cognitive load and promoting English language learning in a multimedia learning environment.
