Abstract The interdisciplinary nature of knowledge is one of the objectives promoted in Colombia, fostering in students the ability to recognize that the curriculum does not work in isolation; if knowledge is complementary, its joint development leads to better academic performance. This research is oriented towards showing an application of the mathematical concept of the slope of the straight line in physics applications, favoring the understanding of the relationships between variables, as occurs with the graphs of kinematics. A group of eleventh grade students from a private educational institution filled in a questionnaire for data collection, based on three situations proposed to answer three open questions in which a reasonably justified answer was required. A part of the group correctly interpreted the graphs by describing the characteristics of the movement in each time interval, but only a few were able to associate the slope of the line as the velocity or acceleration as a function of the variables mentioned in the graph, although their argumentation was based on the angle of elevation of the line.

One of the main challenges at present is to achieve high - quality Education, one which takes into account, along with the whole teaching-learning process, the students’ diverse abilities, skills and cognitive, social and emotional aptitudes. The insertion of multiple intelligences, as well as variables such as creativity, may contribute to the development of singular capacities and students’ school performance. Studying the way these variables are related is imperative. The objective of this investigation consists in analyzing the link between Creativity, Multiple Intelligences and Academic Performance among Colombian primary school students. The design for this study is a non-experimental – descriptive – correlating focus, in which a sample of 40 subjects was studied; 20 girls and 20 boys with an age average of 10,051. All of them studying 5th grade in primary school at the Educational Institution Ana Elisa Cuenca Lara, branch Santa Ana, at the municipality of Yaguará – Hulia – Colombia. Their creativity was estimated through the use of two tests, one subjective, Turtle (1980), and one objective of execution EMUC, Sánchez (2006). To meet the Multiple Intelligences, it was applied a full specific inventory filled out by the valued students’ teachers, taken from Valero (2015). For the academic performance, the 2015’s subjects’ school record was taken as a reference. As statistical analysis, it was applied the descriptive – correlating (Person’s correlation coefficient), with the statistical software SPSS, version 2.2. The results obtained confirm all hypotheses contemplated, making evident a statistically meaningful and positive connection between the three variables analyzed. Finally, it analyzes the results for Multiple Intelligences and creativity as empowering strategies for the valued subjects’ academic development in this investigation’s sample

Purpose of the study: This study intends to scrutinize the factors affecting Malaysian international high school students’ academic performance. Methodology: 117 responses were collected randomly using a questionnaire. The data were analyzed using Partial Least Square (PLS) Main Findings: The findings revealed that future goals as the most crucial factor besides peers’ support, teachers’ support and self-efficacy. Furthermore, it was also disclosed that TL moderated only the self-efficacy on Academic Performance Applications of this study: The study can be used in the context of international high school field or any educational institution as academic performance is a very broad issue discussed in the educational setting Novelty/Originality of this study: Students’ academic performance (AP) is a crucial issue for parents, schools, researchers, and governments. A number of past studies have highlighted the local university students’ AP with less attention given to the performance of international high school students. Thus, this study provides insights pertaining to international high school students

This study aimed at examining the varieties and manipulative skills in computer operations of fourth year high school students of the University of Eastern Philippines System. A self-structured closed questionnaire with 5-point Likert scale was designed for data collection from a sample of 80 high school students and 6 teachers. This study employed the descriptive –correlational survey type of research design, Statistical tools such as frequency counts, percentages, mean, ranking and multiple regression were used to interpret and analyze the data.  Findings revealed that the students were more skilled in terms with their manipulative skills in computer operations, more favorable attitudes while working in computer operation, and a very good academic performance showed in English, Mathematics, and Computer subjects.

INTRODUCTION: There are knowledge gaps in spaceflight pharmacology with insufficient in-flight data to inform future planning. This effort directly addressed in-mission medication use and also informed open questions regarding spaceflight-associated changes in pharmacokinetics (PK) and/or pharmacodynamics (PD).METHODS: An iOS application was designed to collect medication use information relevant for research from volunteer astronaut crewmembers: medication name, dose, dosing frequency, indication, perceived efficacy, and side effects. Leveraging the limited medication choices aboard allowed a streamlined questionnaire. There were 24 subjects approved for participation.RESULTS: Six crewmembers completed flight data collection and five completed ground data collection before NASA’s early study discontinuation. There were 5766 medication use entries, averaging 20.6 ± 8.4 entries per subject per flight week. Types of medications and their indications were similar to previous reports, with sleep disturbances and muscle/joint pain as primary drivers. Two subjects treated prolonged skin problems. Subjects also used the application in unanticipated ways: to note drug tolerance testing or medication holiday per research protocols, and to share data with flight surgeons. Subjects also provided usability feedback on application design and implementation.DISCUSSION: The volume of data collected (20.6 ± 8.4 entries per subject per flight week) is much greater than was collected previously (<12 per person per entire mission), despite user criticisms regarding app usability. It seems likely that improvements in a software-based questionnaire application could result in a robust data collection tool that astronauts find more acceptable, while simultaneously providing researchers and clinicians with useful data.Wotring VE, Smith LK.
