The constructivist learning model is one of the models of constructivist theory in learning, as it generally emphasizes the active role of the learner during learning, in addition to that the intellectual and actual participation in the various activities to help students gain the skills of analyzing artistic works. The current research aims to know the effectiveness of the constructivist learning model in the acquisition of the skills of the Institute of Fine Arts for the skills of (technical work analysis). To achieve the goal, the researcher formulated the following hypothesis: There are no statistically significant differences between the average scores of the experimental group students in the skill test for analyzing artworks before and after.
The theoretical framework included the concept of constructivism and the structural model and its stages, as the researcher presented the taste and analysis of technical work and has adopted in its procedures the experimental one-group approach with two tests (pre-dimensional), as it is the most appropriate approach to achieve the goal of the current research. The research community consisted of male (2264) students of institutes of fine arts for the academic year 2019-2020. The basic research sample chose: The Institute of Fine Arts - the first Rusafa, numbering (30) students, where the choice was made for the fifth stage students - Design Department, after conducting the simple random lottery and conducted the pre-skill test to determine the levels of students in the artistic taste analysis Technical works and comparing its bicycles to the post-skill test scores. The researcher also prepared a form to evaluate the skill performance of students in their implementation of the requirements of the skill test consisted of (10) paragraphs for which he specified a five-point scale, and thus the total score obtained by the student in his analysis of the technical work is equal to (50) stairs . It was presented to the experts, and in light of their observations, it became usable and after honesty and consistency were achieved for them, it was applied to the basic sample of the research. Statistical methods were used; the researcher used the statistical bag (spss) to process the data. After applying the skill test, the results indicated the appearance of a difference in the average score of the experimental group between the pre and posttests, and the direction of this difference referred to the post skill test, due to the sequence followed in students' learning and their acquisition of technical analysis skills according to the constructive learning model.
Based on the results that have emerged, the researcher concludes the following:
1- The ability of the constructive learning model to acquire cognitive information in the technical taste subject for fifth stage students.
2- The emergence of capabilities and capabilities of the fifth stage students in the analysis of technical work after they have acquired the steps of analysis according to the analytical premises of the structural approach.
The researcher suggested conducting the following studies:
1- Conducting a comparative study of the constructive learning model and other forms of learning to determine which is more effective in acquiring technical work analysis skills.
2- Carrying out similar studies to the current study, according to other modern monetary approaches, such as semiotic, deliberative, and deconstructive.
Key words: effectiveness - constructive learning model - acquisition - skill - analysis - technical work.
Background: The immunogenetic predisposition
may be considered as an important factor for the
development of Type 1 Diabetes Mellitus (T1DM)
in association with the HLA antigens.
Objective:This study was designed to investigate
the role of HLA-class II antigens in the etiology of
type T1DM and in prediction of this disease in
siblings, and its effect on expression of glutamic
acid decarboxylase autoantibodies (GADA).
methods:Sixty children who were newly diagnosed
type 1 diabetes (diagnosed less than five months)
were selected. Their age ranged from 3-17 years.
Another 50 healthy siblings were available for this
study, their ages range from 3-16 years. Eighty
apparently healthy control subjects,
Background Doxorubicin (DOX) is a potent antineoplastic agent used in treating various adult and pediatric cancers, but it tends to provoke dose-dependent cardiotoxicity. Ezetimibe (EZE), a cholesterol-lowering drug, has been reported to possess defensive actions against oxidative stress and inflammation, which are two of the main proposed mechanisms underlying the development of DOX-induced cardiotoxicity (DIC), hence, we aimed to inspect the possible protective effect of EZE against DIC in rats. Methods 24 adult male Wistar rats were allocated into four groups of six: control, DOX, 10 mg/kg EZE plus DOX and 20 mg/kg EZE plus DOX. At the end of the study, the experimental rats were anesthetized and blood samples were collected for b

Show MoreLead-acid batteries have been used increasingly in recent years in solar power systems, especially in homes and small businesses, due to their cheapness and advanced development in manufacturing them. However, these batteries have low voltages and low capacities, to increase voltage and capacities, they need to be connected in series and parallel. Whether they are connected in series or parallel, their voltages and capacities must be equal otherwise the quality of service will be degraded. The fact that these different voltages are inherent in their manufacturing, but these unbalanced voltages can be controlled. Using a switched capacitor is a method that was used in many methods for balancing voltages, but their respons

It helps to approximate the palatal cleft and to reshape the nasoalveolar complex prior to primary lip repair. This study aimed to explore types of PSM and the dental speciality provision for infants with CLP in Baghdad. The status of NAM usage and surgeons’ perceptions toward NAM usage were assessed. MATERIALS AND METHODS This is a cross-sectional paper-based questionnaire study that collected responses of surgeons perform primary lip and nose repair regarding PSM. The questionnaire was distributed amongst public and private hospitals in Baghdad. Twenty surgeons were enrolled (only those su

The method is based on the oxidative coupling reaction of barbituric acid with 4-aminoantipyrine and potassium iodate to form purple water soluble stable product at λ 510 nm. Good linearity for both methods was obtained ranging from 2 to 60 μg mL−1, 5–100 μg mL−1 for batch and FI techniques, respectively. The limit of detection (signal/noise = 3) of 0.45 μg mL−1 for batch method and 0.48 μg mL−1 for FI analysis was obtained. The proposed methods were applied successfully for the determination of barbituric acid in tap water, river water, and urine samples with good recoveries of 99.92

It is a basic characteristic of normal blood that plays a major role in the cardiovascular system, especially in the microcirculation. This study explained the kinetics of single cells rouleaux formation one- dimensional aggregate and three- dimensional aggregate, during simultaneous, and the effect of hematocrit on the process of aggregation and sedimentation. The present study was done on forty one healthy subjects. Laser light is passed through a well mixed sample of blood and the forward scattered light intensities recorded continuously. The samples were prepared with different hematocrit, (10%, 15%, 20%, and 25%). Increasing
