Get PDFA study of games in senior high school mathematics classes, 1979
Get PDFThe purpose of this study was to determine the significance of recreational games in the senior high school mathematics classes and how they can be used as instructional devices or aids in a teaching-learning situation. The researcher was interested in achieving two specific purposes: 1. Collecting mathematical games that will motivate, stimulate, and arouse the interests of the math students at R. E. Lee Institute in Thomaston, Georgia. 2. To determine the effectiveness of the mathematical games in the classroom at R. E. Lee Institute. Method and Procedures The subjects were fifty senior high school students. In both classes, the games and recreational activities were used as instructional aids. The subjects were exposed to the games as an aid during the class period. Competition was placed in high esteem. Results A student-opinion questionnaire was administered and scored according to the following levels of agreement: strong level of agreement; moderate level of agreement; and disagreement. Over 70 percent of the subjects highly agreed that the construction of the various manipulatives enhanced their interest level in the mathematics class. There was 25 percent of the subjects who responded with a moderate level of agreement. Four (4) percent responded with a level of disagreement. There were five questions that were related to the implementation of the mathematical games and recreational activities in the classroom. To these questions, over 65 percent of the subjects responded with a strong level of agreement. There was over 33 percent who responded with a moderate level of agreement. Only 1 percent of the subjects disagreed. Conclusion The findings in this study led to the following conclusions: 1. There is an observable change in student interest in mathematics after the implementation of mathematical games and recreational activities. 2. Reactions of the subjects demonstrated that mathematical games and recreational activities are efficient instructional tools/ are fun, remove pressure, encourage peer in teaching and are nonthreatening evaluation of learning. 3. The results of this study suggest that with more time spent with the subjects, the use of games and recreational activities would prove to be even more successful at motivating, stimulating, and arousing student-interest in mathematics. Recommendations On the basis of the findings of this study, the writer made the following recommendations: 1. Putting a halt to dull and dreary mathematics classes should be a major educational goal for the mathematics teacher. 2. Mathematics teachers should continue to use whatever methods that are necessary to turn their students on (educationally), 3. Mathophobia during this era of Neo-Progressive education can be obliterated if all parties concerned would lend a helping hand (principals, department supervisors, teachers, students, and parents)

No full textChild abuse and neglect in the Hispanic community, 1989
No full textThis study had the purpose to measure five variables which are hypothesized to be related to child abuse and neglect in the Hispanic community. The sample for this study consisted of sixty-eight (68) Hispanic families, of which forty-three (43) families were identified from the case files of the Fulton County Department of Family and Children Services in Atlanta, Georgia. The remaining twenty-five (25) Hispanic families were chosen from the Hispanic population in Atlanta, Georgia. An instrument consiting of twenty-seven questions was delivered and picked up at the home of each family. The instrument was selfadministered, and was designed to elicit information about child abuse and/or neglect. The scores from the questionnaire were analyzed to determine the mean, standard deviation, sum of square and analysis of variance. The findings of the study showed that there were statistically significant differences between the groups on four of the five hypothesized variables, namely: isolation, education, language and income. The pattern of means showed that the difference was in the predicted direction
Mechanism of action of ID4 as a tumor suppressor, 2016
Get PDFInitial studies demonstrated that Inhibitor of DNA binding/differentiation protein 4 (Id4) acts as a tumor suppressor in prostate cancer (PCa). To further confirm and investigate the mechanism by which ID4 acts as a tumor suppressor, herein we concentrated on two different approaches. In the first approach we investigated ID4 role as a tumor suppressor by regulating AKT/PI3K pathway. In the second approach, we examined the role ofld4 in blocking the tumorogenic properties of metastatic PC3 cells. Phosphoinositide 3-kinase/Protein kinase B (PB/AKT) pathway regulates multiple biological processes leading to cell survival, proliferation and growth in cancerous cells. We performed immunohistochemistry (IHC) to determine AKT, pAKT and PTEN protein expression in Id4 knockout mouse prostates and PCa cell lines. IHC on Id4 knockout mouse prostates demonstrated a significant decrease in PTEN expression as compared to normal mouse prostates. Consistent with decrease PTEN, the expression of pAKT expression increased. Similar pattern was observed in PCa cell lines: DU145 cells lacking Id4 had low PTEN as compared to ld4 over-expressing DU 145 cells. In addition, Chromatin immunoprecipitation (Ch!P) analysis also demonstrated an increase in the binding of acetylated p53 on PTEN promoter in the presence of Id4. The second approach demonstrated the tumor suppressor function of Id4 in highly tumorogenic and metastatic PC3 cell line. Interestingly, this study demonstrated that overexpression of Id4 in PC3 cells results in decreased tumorogenecity in part through increased expression of Androgen receptor (AR) and its target genes Cyclin dependent inhibitor I (p21) and FK506-binding protein 51 (FKBPS l ). Apoptosis, migration and cell proliferation decreased in the Id4 overexpressed PC3 cells. Mice injected with PC3 + Id4 cells showed decreased tumor size and volume. IHC studies on tumor xenografts demonstrated increased levels of AR, Ki67, and p21 in Id4 overexpressed xenograft. Collectively, our data indicate that 1D4 acts as tumor suppressor by regulating the levels of PTEN by prompting the binding ofacetylated p53 onto PTEN promoter which eventually results in inhibiting P13K/AKT pathway. Furthermore, Id4 not only increases the expression of AR in PC3 cells but also regulates the factors responsible for AR tumor suppressor activity

Perception of first-year teachers concerning the extent to which a mentoring program helps to establish efficacy with regards to organizational skills, effective classroom management skills, creative instructional strategies and strategies for retention intentions, 2009
Get PDFThe purpose of this study was to ascertain the impact of an effective mentoring program upon first-year teachers to acquire efficacy in the areas of organizational skills, effective classroom management skills, creative instructional strategies and strategies for retention intentions. A Mentor Teacher Survey Instrument was administered to new teachers in six middle schools and 27 respondents provided completed surveys. The data were computed using Cronbach coefficient alpha and correlations using version 16.0 of the Statistical Package for the Social Sciences (SPSS). Cronbachs alpha coefficients computations for each subscale were as follows: .883, organizational skills subscale, .796, classroom management subscale, and .910 instructional strategies subscale. The one-sample t tests were performed to compare the mean responses of the non- demographic survey items with the neutral test value of 3.0. A bivariate correlation was used to determine the relationship between first-year teachers sense of efficacy for organizational skills, classroom management, instructional strategies and retention intentions. The statistical significance was established at the .05 level of probability. The SPSS 16.0 bivariate correlation procedure computed Pearsons product-moment coefficient (r) and Spearmans rho (p), to measure the strength of the correlation. A point biserial application of the Pearson correlation was used because one of the variables was dichotomous and the second variable was measured on an interval or ratio scale. An alpha level of .05 was set a priori was used to determine if significant differences! relationships existed between variables of interest. The SPS S data revealed a null hypothesis thus indicating that the respondents expressed a neutral attitude concerning their mentoring experience. The respondents responses revealed 314 negative responses out of a total of 460 positive responses. These 314 responses were computed as the lowest scores assigned by the Likert Scale. A comprehensive study was conducted in 2001 and the researcher made recommendations to the school district to revamp their induction/mentoring program and the system ignored the recommendation; therefore, this researcher supports the 2001 study and confirms that the local school district needs to make significant modification to their induction/mentoring program
