Question

Putting It Together: Online Homework Keeping students engaged in the learning process greatly increases their chance of success in a course. Traditional lecture-based math instruction has given way to a more student-engaged approach where students interact with the teacher in class and receive immediate feedback to their responses. The teacher presence allows students, when incorrect in a response, to be guided through a solution and then immediately be given a similar problem to attempt. A researcher conducted a study to investigate whether an online homework system using an attempt—feedback— reattempt approach improved student learning over traditional pencil-and-paper homework. The online homework system was designed to increase student engagement outside class, something commonly missing in traditional pencil-and-paper assignments, ultimately leading to increased learning.The study was conducted using two first-semester calculus classes taught by the researcher in a single semester. One class was assigned traditional homework and the other was assigned online homework that used the attempt—feedback—reattempt approach. The summaries are based on data from the study.

Accepted Answer

Welcome back, everyone. The next problem is. A university is studying the effectiveness of two different teaching methods in an introductory statistics course. At the end of the semester, students are given a final project that is graded as excellent, good, satisfactory or unsatisfactory. And then we have 3 questions about this. Number 1, what type of variable is the project grade? 2, what is the level of measurement for this variable? And number 3, would a table listing the number of students in each category be more informative than a pie chart for this data? So, by type of variable, we mean is this qualitative versus quantitative. So are we giving the results in some sort of numerical format that's measured, or are we prescribing prescribing, are we having a description? Divided into categories so we can see that this would be. Qualitative It divides. It results in these categories of excellent, good, satisfactory or unsatisfactory. Then question two, what is the level of measurement for this variable? And when we talk about level of measurement for a qualitative. Variable we have two levels which is nominal. Or ordinal. And what determines placement in this is, can the categories be placed in an order. This is as opposed to something like if the categories are, you know, car color. There's no order to that. So, in this case, we have um a grade, excellent, good, satisfactory, unsatisfactory, and these can be placed in order from highest to lowest, lowest to highest. So, we would say that this is an ordinal. Level of measurement And then finally, number 3, would a table listing the number of students in each category be more informative than a pie chart? And the answer is yes, since the table will list exact numbers. A pie chart is good for showing things as a proportion of the whole, so looking and seeing what proportion has each each of these, but it specifically says more informative, and in a table, you will see the numbers specifically that are in each category. So, once again, we were presented with a study on the effectiveness of two different teaching methods. With the final project. Graded as excellent, good, satisfactory or unsatisfactory, we were asked what type of variables the project grade, and it is a qualitative variable. We were asked what what what is the level of measurement for this variable, and that is ordinal. And then we were asked if a table listing the number of students in each category would be more informative than a pie chart, and the answer is yes. See you in the next video.
