The study sought to determine the effectiveness of a training program based on the theory of cognitive flexibility in developing some habits of productive mind and preferred learning methods among female student teachers, by identifying the level of
habits of mind necessary for female student teachers in kindergartens and their preferred learning methods, and determining the procedures of the training program based on the theory of cognitive flexibility. To study its effectiveness in developing some habits of the productive mind and to know the percentage of the contribution of the habits of the productive mind to their preferred learning methods, so the study followed the quasi-experimental approach by designing two equal groups (control and experimental), by preparing a scale of the sixteen habits of the productive mind according to Costa & Kallick’s list. (2009) and a measure of productive mind habits necessary for female kindergarten students, and applying Felder and Silverman’s preferred learning styles scale (Index of learning style, 1999), on a purposive sample consisting of (46) female kindergarten students from the third year because they are in the intermediate learning stage according to the theory. Cognitive flexibility, as the sample represents 20% of the research population, and the results of the study revealed a low level of six habits of the productive mind in the sample: perseverance, control of recklessness, flexibility of thinking, creativity, continuous learning, and striving for accuracy. The sample’s learning preferences also varied between... Methods of processing, perception, input and thinking. The results showed the effectiveness of the training program based on the theory of cognitive flexibility in developing the necessary productive mind habits for kindergarten students. The results also revealed the contribution of productive mind habits to preferences for learning methods, as the habits of the productive mind individually predict preferred learning methods in proportion. It ranges from 31% to 64% in the post-measurement, and the six habits of the productive mind contribute together over time, as they predict preferred learning methods by rates ranging from 18% to 63.8%, with the exception of the processing style, of which the creativity habit predicted 34%. Some Recommendations in light of these results.
The research included the implementation of a laboratory experiment and a field experiment in two successive seasons, where the laboratory experiment was carried out by using columns of PVC columns, where the effect of magnetized water was tested on
several types of soils varying in salinity and spread in the study area east of Aleppo (Kaskis – musharifa Al – Zakia-Rasm al-Hamis). The technology of water magnetization was applied by using a special device manufactured at the Department of Soil Science and land reclamation at the Faculty of agricultural engineering of the University of Aleppo. The device was manufactured for laboratory and field work within a magnetic field whose intensity reached (2000) Gauss. The first type of water was also brought from a well in the village of Rasm al-Hamis (2.1) dS.m-1.the second sample was also brought from a well in the village of musharifa Al-Zakiya (3.4) dS.m-1.the third sample of water used in this study was representative of the water of the Euphrates river canal (0.70) dS.m-1.
The technology of using magnetized water deliberately caused a decrease in the PH values of the three types of water, a slight decrease in the values of the electrical conductivity of irrigation water using magnetized water was also observed, and a decrease in the values of the specific weight of irrigation water after its magnetization was observed in the three types of water used.
Magnetization with the wash coefficient applied by the experiment (15%) contributed to reducing the electrical conductivity values of the three soils, as it was noted that the effect of the magnetization technique was of a significant nature on the soils of the Hamis sketch, where before the experiment they were classified as high-salinity soils and by the effect of the magnetization technique, at the end of the experiment they turned into low-salinity soils. The results obtained from the Rasm al-Hamis soil confirmed that irrigation water with a washing coefficient, whether magnetized or non-magnetized, effectively contributed to the washing of salts from the surface layer of the soil compared to the soil salinity value before the experiment, which amounted about (4.1) dS.m-1, as the magnetized Euphrates water contributed to the washing of salts from the surface layer of the soil by 10% increase compared to the same treatment irrigated with non-magnetized water, as well as when using the magnetic wells of Rasm al-Hamis and Musharafat Al-Zakiya, where the magnetized water contributed to the washing of salts by 19% and 9.8% more than the same transactions irrigated with ordinary water for the surface layer of the soil, and the decrease was of a significant nature. The results in the soil columns also indicated that a significant decrease in the SAR and ESP values of the three soils was achieved, and therefore magnetization had an important role in washing the sodium cation from the soil. With regard to the future leachate from the soil columns, higher values of electrical conductivity and the rate of absorbed sodium were observed in the leachate of transactions irrigated with magnetized water compared to the leachate of transactions irrigated with ordinary water without magnetization for the three soils. this confirmed the role of magnetization technology in washing salts from the soil solution, especially sodium cation. this has been positively reflected on the physical properties of the soil, where the magnetization technology contributed to improving soil porosity values. the improvement was significant in the soils of Rasm al-Hamis and as a poke and not significant in the soil of Musharafat Al-Zakiya.
Moving on to the field experiment, the field experiment was designed using a completely randomized block design with (3) replications, so that the first factor includes irrigation techniques: magnetized water (M) and non-magnetized water (NM), and the second factor is the addition of organic fertilizers to the soil, which included three coefficients: municipal fertilizer (O), humic acid (H) In addition to the control treatment (C). The area of the experimental piece was 16 m2, The number of plants within the experimental plot reached 120 plants. The Maize crop was planted on 29/6/2021 for the first season and on 9/7/2022 for the second.
The results indicated the role of magnetization technology in reducing the electrical conductivity values of the studied coefficients compared to the control treatment coefficients in the surface and subsurface layers with an average value of 10.28%. The results also confirmed that magnetization plays an important role in washing the Na+ ion, and this was clearly reflected in the SAR value of the soil, where the SAR value when irrigated with ordinary water was about 3.16, while it decreased to 2.79 when irrigated with magnetized water, and this decrease was of a significant nature, which in turn affected the reduction of ESP values of the soil.
The results indicated that magnetization clearly affected soil cations, especially Na+, and also directly affected the SO4-2 ion, where the concentration of SO4-2 decreased by 14.4% when irrigating with magnetized water compared to the control treatment. The results confirmed the role of the magnetization technique in improving porosity values.
The data pointed to the important role of municipal fertilizer, potassium Humate in reducing the electrical conductivity values, and the treatment of municipal fertilizer was statistically superior to potassium Humate, whether irrigation with magnetized water or ordinary water. Organic compound with magnetized water also contributed to improving the physical qualities of the soil, which was positively reflected on the values of the index of deterioration of soil properties compared to the control treatment coefficients. This improvement in the physical and chemical properties of the soil positively affected the availability of nutrients in the soil in general, and microelements in particular, which contributed to an improvement in the productivity values of the Maize crop, which reached its highest value when irrigated with magnetic water about 7.43 tons/h, and potassium Humate with irrigation with magnetic water raised the productivity value to 8.49 tons/h, while the treatment of municipal fertilizer with irrigation with magnetic water surpassed the rest of the transactions, where productivity reached about 9.1 tons/h in the first season of the experiment, and the productivity values also improved slightly in the second season compared to the first.
