The study was conducted on the use of Maple software to reduce student teachers’ errors in Differential Calculus at Evangelical Presbyterian College of Education, Volta Region - Ghana. The research design for the study was quasi-experimental non-equivalent control group design. Convenience and simple random sampling techniques were employed to obtain a sample of 104 student teachers, which comprised 53 student teachers in the control group and 51 in the experimental group. Test items were the instruments used for data gathering. Descriptive, paired samples t-test and independent samples t-test were used in analyzing data. Descriptive content error analysis revealed that student teachers committed many conceptual, procedural and technical errors when solving tasks in the differential calculus. The results also indicated that there was a statistically significant difference between student teachers’ of the experimental group exposed to the use of Maple software in learning differential calculus to control groups exposed to traditional methods. Consequently, it was recommended that Maple assisted instruction be incorporated in the teaching and learning of differential calculus in the school; and also there is the need for the mathematics teachers in the school to employ blended teaching approaches, in which Maple software are used simultaneously to enhance teaching of mathematics concepts.

A quasi-experimental study was conducted to find out the effect of honey mouth-care on xerostomia among semiconscious and unconscious patients in a selected hospital of Odisha. In this study, an experimental research approach and non-randomized control group design were adopted. 40 patients were selected by the non-probability purposive sampling technique and who met the inclusion criteria were selected for the study. A self-structured interview schedule and record analysis performa were used for collecting socio-demographic data. The Challacombe Scale was used to assess the level xerostomia among the selected patients. In unpaired 't' test, there was a significant difference between the level of xerostomia among the experimental group and control group as 't' value was -6.03 (p<0.0001), which represented that honey mouth-care was effective in reducing the level of xerostomia. In paired 't' test, there was a significant difference between the level of xerostomia in pre-test and post-test score among the experimental group as 't' value was -6.45 (p<0.0001) which represented that honey mouth-care was effective in reducing the level of xerostomia. The chi-square association between levels of xerostomia with selected demographic variables revealed that there was a significant association between the level of xerostomia with age and history of the previous hospitalization. No significant association found between the level of xerostomia with the socio-demographic data and the duration of semi-consciousness or unconsciousness and duration of xerostomia. The findings of the study revealed that honey-mouth-care was highly effective in reducing xerostomia among semiconscious and unconscious clients.

Hydroxyapatite (HA) is a bioceramic with excellentbiocompatible properties, and composition and crystal structure similar to apatite in the human dental structure and skeletal system. A number of researchers have attempted to evaluate the effect of the addition of HA powders to increasemechanical properties of restorative dental materials. In this study, HA was synthesized using chicken eggshell as calcium source for synthesizing HA by using precipitation technique. The aim of this study was to determine the effect of incorporation of eggshell-derived HA on the surface  hardness GIC (Fuji IX GP). Specimens were divided into two groups: group GIC without incorporation of HA as control group (n = 16) and group GIC with incorporation of 5% HA as experimental group (n = 16). Total of specimens were 32 cylinders 5mm diameter and 2mm height. Surface hardness GIC was measured with vickers microhardness tester. Data wasanalyzed by unpaired T-test. The mean of surface hardness for GIC control group was 51.37 ± 1,63VHN and the experimental group was 56.60 ± 1,22HVN. The results T-test showed a significant difference between groups (p<0.05). It can be concluded thatincorporation of eggshell-derivedHA could increasesurface hardness of GIC.

The quest for better strategies in teaching is a never-ending process. This scenario is heightened more by the myriad online instructional materials fit for classroom use. The study aimed to determine the effectiveness of video lecture materials for statistics proficiency of first year students of Davao Doctors College.The researchers employed quasi-experimental design that involved purposively chosen 31 students for the control group and 26 students for the experimental group. The control group received traditional instruction while the experimental group utilized video lecture materials as the instructional tool. The questionnaire consisted 50 multiple choice items and established a reliability index of .82. This investigation used t-test analysis to establish the same level of statistics proficiency among the students before the conduct of the study. The study concluded that both learning strategies were effective in teaching students the basic concepts of statistics as indicated by the significant improvement of their pre-test to posttest scores. Although the posttest results of the students who were taught using video lecture materials were higher than those supervised using lecture method, the significance of this difference was never established. Thus, the use of video learning material as an instructional tool in statistics is equally effective with the traditional lecture method. Keywords - Mathematics education, video lecture material, effectiveness, statisticsproficiency, quasi-experimental design, significant difference, t-test, Philippines
