Attitudes Towards Learning

A positive attitude correlates to successful learning; while a negative attitude leads to poor learning. The present study aimed to compare the pre-service biology teachers’ attitudes towards learning biology and assessing their attitudinal change before and after being taught by resource-based instructions (RBI) in Rwanda. A survey-research design was used, in combination with a quasi-experimental control group, and the equivalent time-series designs. Pre-service biology teachers were taught at a public university in three separate groups, with one control group and two experimental groups. Each group received a pre-attitude and a post-attitude assessment. In contrast, at a private university, they were taught as a single group, in a series of instructions, starting with the lecture method, followed by animation-based instruction and small- group laboratory activities, in which at each stage, the pre-service biology teachers received the same assessment. The biology Attitudinal Scale showed a Cronbach alpha reliability of 0.625 before its use. The data were analyzed quantitatively; and the results revealed no statistically significant difference between the public and the private pre-service teachers’ attitudes before learning microbiology. After the teaching interventions, the results revealed that both the traditional and the resource-based instructions improved the pre-service biology teachers’ attitudes towards learning biology, as a result of their improved maturity and their anticipated future teaching career.

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

Breastmilk is the only perfect and best food for babies because it contains the nutritional elements needed by babies for optimal growth and development. Although the rate of exclusive breastfeeding in the Pringsewu Regency has increased from year to year, support for community participation and empowerment in health development has not been optimal. One solution that can help overcome barriers to exclusive breastfeeding is hypnobreastfeeding. The purpose of this study was to determine the effect of hypnobreastfeeding on the motivation of breastfeeding in the Pringsewu Regency in 2019. This research is a quasi-experimental research with pre-post-test design with a control group design. The sampling technique was purposive sampling with a sample size of 48 pregnant women from term to breastfeeding. Data analysis was done by using the Independent Two Mean Difference test (T-Test) using the Paired Sample Test. The results of the study on the Paired Sample Test showed a significant value (p) of 0.004, meaning that there was a significant difference in the motivation of breastfeeding before and after hypnobreastfeeding. Midwives always provide hypnobreastfeeding therapy and lactation education to help increase motivation for breastfeeding as part of efforts to increase exclusive breastfeeding and breastfeeding for up to 2 years or more. For other researchers, it is necessary to carry out further research with other variables that can affect the motivation of breastfeeding.

Completeness of nursing documentation is one of the quality indicators of nursing care. Based on the nursing practice law no. 38 article 37, nurses in carrying out Nursing Practices are obliged to document Nursing Care in accordance with the standards. Documentation in Inpatient PKM consisting of Siko, Jambula, and Sulamadaha PKM itself, based on the observations of researchers found several obstacles, namely, the lack of nurses given the large number of PKM programs that must be run, varying levels of education so documentation has a different understanding, this also supported by the lack of education and training related to temporary nursing care documentation relating to the Nursing Process and Documentation experiencing some recent changes. The purpose of this study was to determine the effect of applying the nursing documentation format for the model Problem-Oriented Record (POR) on the performance of nurses in the Inpatient Health Center in Ternate City. The design of this study is quasi-experimental, namely, pre and post-test without control group. The population is nurses with 41 people in PKM Inpatient who are in Ternate City. Samples were taken by total sampling technique and analyzed using statistical tests t-test, Anova, and correlation. The results of the study found a significant difference between the performance of nurses before and after the application of the documentation format for nursing care in the POR model (p-value: 0,0005 α: 0.05) while the characteristics of respondents included age, sex, marital status, length of work and education had no effect on performance.

Purpose – This paper aims to research about the effect of mind–body training on the development of emotional competencies of managers. Design/methodology/approach – Quasi-experimental design, i.e. before and after (test–retest). Findings – Results showed that the experimental group, after training, achieved around 15 per cent higher scores compared to results before training on all three subscales of an emotional skills and competence questionnaire (ESCQ-45), a statistically significant improvement in scores. The control group (no training) scores showed no significant difference. This result indicates support for the view that emotional intelligence may be treated as a competency and is responsive to training programmes. Research limitations/implications – Emotional competencies are still a contested concept. The participants may provide socially desirable responses because of the self-assessment questionnaires. The sample is not a representative sample of European managers; hence, there is a limited generalisability of the results. Practical implications – These research findings indicate Mind–body training is a practical method for people to improve the management of their emotions, and hence impact positively on core organisational activities. Originality/value – This is the first research on this mind-body training (emotional relief technique) in an eight-week programme in a management context. The findings indicate the positive impact that can be achieved on emotional competencies scores from this method of self-development.
