In this paper, the velocity and acceleration of four water rockets is determined, using the least squares method and the Euler’s method. The position and time data are obtained from the analysis of slow-motion videos of the launch of the rockets, processed with the video analyzer software “Tracker”. This experiment is proposed as a pedagogical tool for the exploration by students of high school and first semester of sciencie and engineering of basic concepts of kinematics and dynamics in systems with variable mass and acceleration.

Reading is the basic in learning every subject. The more understanding the text, the more information students can gain. However, the reading materials that the students use is not appropriate based on syllabus. Therefore, the reading materials should be developed to fulfil the syllabus and the students' needs also. Because English is included Content Area Reading, so the development of reading materials is based on content area which focus on strengthen the vocabularies, specifically the unfamiliar ones, by giving glossary and related pictures. The developed text is only focus in the first semester which is descriptive and recount text. The research was conducted at SMP Muhammadiyah 7 Medan. The data was taken from interviewing the English teacher and distributing questionnaires for 30 students in grade VIII-4. The data showed that students need materials which is related to their environment and constructed by familiar vocabularies. Based on the result of the study, conclusion and suggestion are directed to the English teacher who is teaching in that school to provide reading materials based on syllabus and students' needs regularly.

This study has several objectives first prove a significant difference in understanding of the assets, liabilities and capital between the students from SMK Accounting Department, High School and Madrasah Aliyah Department of Public IPS IPS majors. Prior to hypothesis testing performed prior sample collection is 68 students who have graduated from vocational secondary education level majoring in Accountancy, SMA study of majoring of IPS science Madrasah Aliyah common in college majoring in social studies at the Bung Hatta University of Padang. Type of data used are obtained through deployment of primary questionnaire. Variable study is a basic understanding of accounting concepts consisting of cash, liabilities and capital, while the distinguishing dimension is the level of formal education of students in the past. The process of hypothesis testing is done by using a statistical test that is using the Kruskal Walls. Based on the results of testing the first hypothesis of no difference in the understanding of accounting students from vocational education majoring in accounting, SMA students and Madrasah Aliyah major of IPS science. in understanding the basic concepts of accounting view of the assets. The second hypothesis found differences in the understanding of accounting students from vocational education majoring in accounting, high school social studies department, and public Madrasah Aliyah Department the major of IPS science of the basic concepts of accounting in view of the obligation. The third hypothesis found no differences in accounting students' understanding of vocational education majoring in accounting, SMA student, and Madrasah Aliyah general social studies department of the basic concepts of accounting view of capital.

This study was conducted to examine how first-year engineering students conceptualize the Entrepreneurial Mindset (EM) and how that conceptualization changes over the course of their first semester of college, using the Kern Entrepreneurial Engineering Network (KEEN)’s 3Cs as a starting point. Students enrolled in an introductory, multidisciplinary design course responded to biweekly reflection prompts on their educational experiences (either in high school or as a first-year college student) and related this experience to one of the 3Cs of EM: Curiosity, Connections, or Creating Value. Results indicate that students’ conceptualization of the 3Cs often align with definitions of EM from KEEN, as well as foundational works in the entrepreneurship field, and that their interpretation of each of the 3Cs does change during their first semester in college. For instance, students were less likely to write about curiosity and more likely to write about creating value at the end of the semester compared to the beginning.

In today’s generation, mathematics will be very useful in our daily lives. Using mathematics is a tool when meeting life-related circumstances involving computation; hence mathematics is particularly important on a daily basis. This research study is entitled “Mindset and Level of Anxiety in General Mathematics among Grade 11 students”. The study focused on the association between the mindset of the students if it is fixed or growth and their anxiety levels in General Mathematics. This research study is quantitative research; it is using a descriptive-correlation design. This study was answered by all Grade 11 students who are taking General Mathematics in the first semester in Jagobiao National High School. In gathering the data, the checklist survey questionnaire was being used. The result found out that students of Jagobiao National High School are more on growth mindset. Students with a growth mindset lead to a moderate level of anxiety in General Mathematics. By using the chi-square, it tells that mindset and level of anxiety has a significant difference. School heads, faculties, and staff can also have monthly activities to diminish the anxiety level of the students. They could also motivate or cheer up students to become growth-minded.

This study explored the impact of Advanced Placement and honors course enrollment and high school grade point average (GPA) on first-semester college GPA. Data were collected from 131 college freshmen enrolled at a minority-serving institution who graduated from a public school during the previous academic year. A four-step hierarchical multiple regression analysis indicated that family structure, college status, enrollment in one or more Advanced Placement courses, and enrollment in five or more honors courses accounted for a significant amount of variance explained in first-semester college GPA, both individually and in combination. High school GPA intervened in these variables relationships with first-semester college GPA accounting for a significant amount of variance. Based on these findings, opportunities for future research and implications for K–12 schools and colleges are provided.

Three forms of the QT (1, 2, and 3) were administered to a randomly selected sample of 42 black entering freshmen at a Midwestern university. Scholastic Aptitude Test scores and high school rank were also used as predictor variables for grade point average. The results indicated that the Quick Test provides a better prediction of first semester college grades than either high school rank or the aptitude test scores.

The Twilight School at Danbury High School in Connecticut helps students who are in danger of failing their freshman year to get back on track. In its first year, the program offered special credit-bearing after-school courses in biology and English to students who failed those classes in their first semester. The smaller class sizes and informal atmosphere engaged the students and enabled the DHS educators who taught these courses to experiment with new-to-them instructional techniques, such as blended learning, some of which were later rolled out schoolwide. Of the 75 students who completed the course, 64 earned credits that helped them advance to their sophomore year.
