Electrocardiogram Ecg

Educators have placed an emphasis on the development of laboratory materials that supplement the traditional lecture format. The laboratory materials should encourage active learning, small group discussion, and problem-solving skills. To this end, we developed a virtual experiment designed to introduce students to the theory and application of the electrocardiogram (ECG) and the mean electrical axis (MEA). After reviewing background material, the students will analyze ECG recordings from two individuals who underwent a series of experimental procedures. The students are challenged to reduce and analyze the data, calculate and plot the MEA, and answer questions related to the theory and application of the ECG. In conducting the virtual experiment, students are introduced to inquiry-based learning through experimentation.

Abstract Common student errors and misconceptions can be addressed through the method of classroom voting, in which the instructor presents a multiple-choice question to the class, and after a few minutes for consideration and small-group discussion, each student votes on the correct answer, using a clicker or a phone. If a large number of students have voted for one particular incorrect answer, the instructor can recognize and address the issue. In order to identify multiple-choice questions that are especially effective at provoking common errors and misconceptions, we recorded the percentages of students voting for each option on each question used in 25 sections of integral calculus, taught by 7 instructors, at 4 institutions, over the course of 12 years, on a collection of 172 questions. We restricted our analysis to the 115 questions which were voted on by at least 5 different classes. We present the six questions that caused the largest percentages of students to vote for a particular incorrect answer, discuss how we used these questions in the classroom, and examine the common features of these questions. Further, we look for correlations between question characteristics and the mean percentage of students voting for common errors on these questions, and we find that questions based on general cases have higher percentages of students voting for common errors.

We developed four innovative, creative, and fun educational tools to promote active learning, enhance problem-solving skills, and encourage small group discussion. Furthermore, the tools encourage deductive reasoning and critical thinking rather than passive memorization of material. The tools include crossword puzzles, hidden messages, word scrambles, and word searches. These tools were developed using two computer programs: the Crossword Construction Kit and The New Puzzle Factory. Instructors are encouraged to optimize the value of the tools by using the additional options presented at the end of each of the puzzles. The additional options encourage students to become active learners by creating their own tools. Although the principles of these four tools can be adapted to many disciplines, these specific games focused on gastrointestinal physiology. Our goal was to create tools that can be used either inside or outside the classroom to complement and enhance the lecture.

The present study aims at exams the effectiveness of small group discusssion in teaching reading comprehension of narrative text of the tenth -grade students of SMA NEGERI 1 WOLOWAE. Teaching reading comprehension is recommended in Senior High School because reading comprehension is very important. In competence based on curriculum, students are understanding to comprehending the conten of the text. The research is carried out through quantitative research with an experimental method because the researcher gives treatment in teaching writing. In conducting the research, the researcher uses one group pre-test-post-test design. The researcher gave pre-test before treatment and post-test after treatment to get the data. In this research, the researcher took twenty students as a sample. The result of the study shows that the score of pre-test was 61 while the mean score of post-test was 81.5 and the mean score of differentiate was 20.5. On the other side, it was found that the result of t-score is bigger than t-table (9,71 > 2,11) at the significant level of 0,05. Therefore, based on the hypothesis testing, we can conclude that the Alternative Hypothesis (Ha) is accepted while the Null Hypothesis (Ho) is rejected. Based on the result, it can be concluded that the using small group discussion as a method is effective to increase students reading comprehension of the students’ of Senior High School, especially for the tenth grade of SMA NEGERI 1 WOLOWAE. Based on this findings, it is suggested, that the teacher should try to apply an interesting method.

This research in intended to find out the effectiveness of small group discussion technique in improving the students’s speaking ability. It was conducted at SMA Negeri 1 Ratahan in which one class of the first-year students of the school was the sample. The data of the research were obtained by using test in the form of pre-test and post-test. The result showed that the scores of the post-test were higher than that of the pre-test. The mean of the post-test is 8.2 and the mean of the pre-test is 6.7. Teaching speaking skill by using small group discussion technique can improve the students’ ability in speaking. Small group discussion technique can give the students opportunity to practice their language. In small group discussion, they can express their ideas and thought freely. It will be better for English teacher to vary the techniques of teaching to avoid boredom that might appear to the students.

This study was aimed at finding the effect of small group discussion in improving speaking skills at the seventh year students of SMA Plus NW. This research was conducted as quasi-experiment using a quantitative approach with One-Group Pretest-Posttest design. The population of the research was the eleventh-grade students of SMA Plus Munirul Arifin NW Praya in academic year 2018/2019. Each class consists of 28 students. The total population was 95 students. In this study, the researcher took one class as a sample. The class was eleventh Grade of MIPA 1 consisting of 28 students as the experiment. The researcher gave treatment to the experimental group and it used Small Group Discussion as the treatment of teaching speaking. The purpose of using the Small Group Discussion was to give new inspiration that can be applied in teaching speaking. Referring to the result pre-test and post-test showed that the sig (2 tailed) > 0.05, it means that the null hypothesis (H0) is rejected and the alternative hypothesis (Ha) is accepted. So the use of Small Group Discussion in teaching speaking is effective. The value of t-test was higher than the t-value of t-table (t-test 8.5148 > t-table 2.006). It showed that teaching speaking using small group discussion has a positive effect to improve students' speaking skill. Besides that, the result of the mean of post-test was higher than the mean of pre-test (M2 = 18.43 > M1 = 14.25). It means that teaching speaking by using small group discussion was more effective than teaching speaking without using small group discussion. In addition, small group discussion can improve students' speaking skill in the eleventh-grade students of SMA Plus Munirul Arifin NW Praya.

Active involvement in the learning process has been suggested to enhance creative thinking, judgement, interpretation, and problem-solving skills. Therefore, educators are encouraged to create an active-learning environment by incorporating active-learning strategies into the class. However, there is very little documentation of the effectiveness of active-learning strategies. Furthermore, faculty are often reluctant to incorporate new strategies without documentation of the effectiveness of these strategies. To address this concern, we compared the performance of two individual classes on an identical respiratory physiology examination. One class was taught respiratory physiology using active-learning strategies. The other class was taught respiratory physiology using the traditional lecture format. The results document that students who learned using active-learning strategies did significantly better ( P < 0.05) on the respiratory physiology examination than students who learned by the traditional lecture format (61 ± 2.2 vs. 86 ± 1.0). Thus, by actively involving students in the learning process, academic performance is enhanced.
