“…Beneficial effects of rhizobium on French bean have been reported by various workers under different climatic and soil conditions [55,56]. Ndlovu [57] reported that nodulation was significantly affected by inoculation with Rhizobium phaseoli. Nodule dry biomass plant −1 was significantly increased by approximately 51.11 per cent with inoculation compared to uninoculated treatment in 2012-2013.…”

French bean (Phaseolus vulgaris L.) is used profusely by the common people as an alternative diet of protein. The sparse nodulation in French bean mainly may be due to lack of threshold level of specific rhizobial cells in soil at the time of sowing. The isolates streaked on YEMA with BTB changed to yellow color showing the production of acid which is the characteristic of Rhizobium. Utilization of different carbon sources is an efficient tool to characterize the isolates. Plant growth promoting rhizobacteria is the beneficial rhizobacteria inoculation of which increases growth and yield of French bean through different direct and indirect mechanisms. Inoculation of French beans with rhizobial and rhizobacterial isolates found to be improved growth, physiological, quality parameters and grain yield through symbiotic N2-fixation capacity and plant growth promoting abilities. Co-inoculation of rhizobial and rhizobacterial isolates enhanced the growth and grain yield of French bean. These isolates may be used as consortium to improve the growth of French bean, which may reduce the dependency of farmer on chemical fertilizer as well as risk of pollution. In this chapter characterization of Rhizobium and plant growth promoting rhizobacteria and their effect on plant growth has been reviewed.

“…Theme 3: Readiness in Learning Mathematics Among all of the research articles for this study, four of them indicated that the experience of the students while using graphing calculators provided them with the sense of confidence in learning the subject matter (Ndlovu, 2019;McCulloh, 2007;Tan, 2011;& McCulloh, et.al., 2013). Confidence refers to the feeling or belief that one can rely on the calculators as a tool in answering problems or re-checking values along their solution process.…”

“…Using graphing calculators entails students to memorize some key pressing steps and mechanical processes. According to Ndlovu & Ndlovu (2020), although learners acknowledge the potential of graphing calculators in assisting them in their learning, they also mentioned that they experienced some technical difficulties in setting the right windows of the tool. McCulloch, et al (2013) also found that some students easily experience mistakes in inputting information into the calculator making it difficult to trust the results.…”

The Use of Graphing Calculators in Teaching Mathematics: A Meta-Synthesis. Objectives: This study aimed to explore the use of graphing calculators as a tool in teaching and learning mathematics employing a meta-synthesis method. Methods: A meta-synthesis was used in this study. The final 16 articles used in this study were the result in using the Critical Appraisal Skills Programme (CASP) checklist and the PRISMA 2020 flow diagram. Findings: Six themes emerged from the data: (1) influences students' solving and basic skills; (2) the need for complex technical skills; (3) readiness in learning mathematics; (4) facilitative role of the teachers; (5) excellent aid for better comprehension and representation; and (6) increases students' cognitive achievement. The study's meta-theme emerged as the "exploration and navigation on the use of the graphing calculators". Conclusion: The use of graphing calculators was found very useful in teaching mathematics. It is recommended that a training the use of the graphing calculator be given to both teachers and student; the offering of elective subjects which deal on the use of different technologies useful in Math teaching/learning be considered.

“…In particular, the most commonly mentioned tools in the literature included: the "Geometer's Sketchpad" [33]; the "Z+Z Intelligent Education Platform" [34]; and "Jinhua Branch of Mathematical Platform" [35]. There also included the "Primary Mathematics Companion" [36]; the graphing calculator [37]; "Logo language" [38]; "geometric reasoning" [39]; the "Mathematica package" [40]; the "MP_Lab" [41]; the number sense game (NSG) [42]; the "DM_Lab" [43]; the "Children's Enlightenment Master" [44]; the "Child Star of the Enlightenment of Gray Ducks" [45]; the "King of Oral Calculation" [46]; the "Haifeng Learning Courseware" [47]; and other educational software programs and math games, as well as programs such as "Bingo" [48]. These learning tools focus on middle-school mathematics more than primary-school mathematics.…”

In terms of the leap-forward development for education experiment, both the Chinese and English educational experiment have been very successful, while the progress of the children's mathematics education experiment in China has been relatively slow. It is believed that the main reason for this is the lack of an efficient cognitive tool or system that supports students' study and exploration and correspondingly covers the whole curriculum of children's math education. In recent years, basic mathematics education cognitive tools have undergone rapid development, whereas the lack of a common normalization method for continued in-depth inquiry of the relationships among Objects, Algebra, and Geometry (OAG) has led to the fragmentation of students' mathematical knowledge. Thus, it is difficult for students to develop a systematic understanding of mathematics. Therefore this project attempts to construct a Children's Mathematics Exploring System (CMES), which integrates with cognition theory, method, and contents of basic mathematics education to query the essence of the relationships among OAG. Specifically, the functions of CMES include the following: (1) providing cognitive tools with typical characteristics for the relationships among OAG; (2) offering a general normalized open system on which sustainable in-depth research can be conducted and a conversion tool through which the complete textbook unit of the basic mathematics education can be converted to reveal the relationships among OAG; and (3) presenting a set of cognitive theories, methods, and a system of basic mathematics education to further explore the relationships among OAG. This project will accelerate the development of cognitive technology in basic mathematics education, widen its practical applications, reduce the difficulty of mathematics cognition, and finally improve the quality and efficiency of basic mathematics education.INDEX TERMS Children's math education, exploring system, educational technology.
