Measuring the effectiveness of online problem solving for improving academic performance in a probability course

Research on impact in student achievement of online homework systems compared to traditional methods is ambivalent. Methodological issues in the study design, besides of technological diversity, can account for this uncertainty. Hypothesis This study aims to estimate the effect size of homework practice with exercises automatically provided by the ‘e-status’ platform, in students from five Engineering programs. Instead of comparing students using the platform with others not using it, we distributed the subject topics into two blocks, and created nine probability problems for each block. After that, the students were randomly assigned to one block and could solve the related exercises through e-status. Teachers and evaluators were masked to the assignation. Five weeks after the assignment, all students answered a written test with questions regarding all topics. The study outcome was the difference between both blocks’ scores obtained from the test. The two groups comprised 163 and 166 students. Of these, 103 and 107 respectively attended the test, while the remainder were imputed with 0. Those assigned to the first block obtained an average outcome of −1.85, while the average in the second block was −3.29 (95% confidence interval of difference, −2.46 to −0.43). During the period in which they had access to the platform before the test, the average total time spent solving problems was less than three hours. Our findings provide evidence that a small amount of active online work can positively impact on student performance.

ANALISIS KEBUTUHAN PENGEMBANGAN VIDEO PEMBELAJARAN MATA KULIAH PROGRAM LINIER

Linear Programming is a course under the scope of algebra that must be mastered by mathematics education students. The low ability to solve linear programming problems can affect student performance when they become a teacher. This study aims to analyze the need for developing learning videos in Linear Programming courses for students of the Mathematics Education Study Program. The method used is development research which consists of Preliminary Analysis, Product Prototype, and Assessment. The research subjects were 30 students in the 7th semester of mathematics education and had attended online Linear Programming lectures in the previous semester. Data were collected by conducting written tests, questionnaires, and interviews and analyzed quantitatively descriptively. The results of the written test analysis showed that the students' ability to solve linear programming problems was low. Based on interviews, it is also known that students are not enough just to learn through modules and virtual meetings. Students tend to need learning videos/records to repeat explanations when studying the material independently. Therefore, there is a great need for learning videos that can optimize online learning of Linear Programming courses.

Investigation of impact of Augmented Reality Technology on Interactive Teaching Learning Process

Augmented Reality (AR) is growing technology that superimpose 3D images onto real world. This enhances the user’s real-world experience. This potential of AR can be utilized effectively in teaching learning for engineering graphics course.There is visualization limitation for engineering students entering in first year, and this leads them to face difficulty in understanding and developing orthographic, isometric and section view of models. AR can empower the students to visualize the actual virtual object in 3D view to match their imagination with augmented object. In this regard initially a framework of AR is conceptualized for the course of engineering graphics & an AR application is developed. This paper mainly focuses on investigation & impact of AR technology on interactive teaching learning process in engineering graphics. Impact of this technology is measured by student’s performance in AR interactive test. The result shows increase in student’s performance in written test by 18.52% in engineering graphics and in mental rotation test by 28.97%.
