The intersection of two lines was studied in grade 7, junior high school. This geometry material is very important, as the basic 3 dimensions that students will learn at the high school level. Exploring and persuading the two properties of vertical lines is the most difficult thing in teaching. Traditional teaching uses methods such as observation, drawing, measurement, and comparison to derive the properties of vertical lines, and expresses the properties of vertical lines in finer words, which easily create greater difficulty for students to understand. This research uses research and development methods, tries to use mathematical software to teach lines and angles and optimizes the basic concept of lines and angles. The results of this study provide specific references to the graphs and geometry of junior high school mathematics.

The Impact

A quasi experiment with interview was adopted to study the aptness of using 3D animations as an instructional method to introduce programming concepts to students at the Senior High School level. This research work was conducted with 100 students of Akroso Senior High School in the Birim central municipality of the eastern region of Ghana who were generally programming novice. Programming concepts considered included programming environments, loops, functions sequential and conditional execution of programs. A paired t-test carried out on the results of the performance test presents a p-value of 0.008 indicative of a numerically significant difference between the mean marks of participants during the experiments that used 3D animation method as against the experiments that used the text base method. Results from the interview showed that the instructional method used had impact on the performance of the learners. The use of 3D animation method presented programming concepts in a form that the learners can understand, motivates them to pursue programming related courses at a higher level and also impacts positively on their performance.

The purpose of this study was to examine inservice high school band directors’ perceptions and applications of democratic rehearsal procedures in concert band rehearsals. Respondents ( N = 216) were members of the National Association for Music Education who were currently teaching concert band at the high school level. Respondents indicated that “identify and describe opportunities for individual and ensemble performance improvement” and “student-led sectionals” were considered the most important democratic rehearsal procedures for their students to experience. These same procedures were also the most frequently used democratic rehearsal procedures. Analysis of open-ended responses revealed that respondents believed student ownership, student engagement, and student growth as musicians and leaders were advantages to implementing democratic rehearsal procedures. Potential disadvantages included issues related to student ability, rehearsal time limitations, unfamiliar classroom dynamics, and availability of classroom resources. Implications for music teachers are discussed.
