Abstract

The current study explored the effects of stimulus complexity and familiarity on tracking accuracy between male and female postgraduate students in Malaysia. Since online courses are not restricted by location, the convenience of recording classes has become a steady trend, especially during the COVID-19 period. However, some are also skeptical about the efficacy of online teaching and learning through the digital environment and believe that the stimulus generated on these foundations will result in undesirable consequences (Dhawan, 2020). As student attention determines their tracking accuracy, external factors like stimulus complexity and familiarity tend to be an obstacle for students to be attentive.  In this quantitative experimental study named "Simon Effect", 24 postgraduate students (12 males and 12 females) in a Malaysian public research university were used as samples to test whether or not gender plays a role in tracking accuracy. Results show that gender does not influence the tracking accuracy of postgraduate students. At the same time, the stimulus complexity and familiarity do influence the tracking accuracy of the postgraduate students. The implication of the study lies in promoting the teaching and learning sessions not only for a postgraduate student but for all the students in different educational levels during the COVID-19 period and maximizing the educational outcomes.

Abstract

Multiple representations are beneficial for meaningful understanding. However, three or more representations may add to the cognitive overload of students, if not in interactive diagrams and dynamic geometry. How a well-known representation consisting of more than 3 or more representational registers may overcome the problem of cognitive overload without being too complicated. In this study, an old but well-structured representation that was used even over 40 years was analyzed. The critical points of a function, asymptotes, x / y-intercepts, inflection points, and graphing can be identified easily. It is prepared in the form of a table and the factors of the first derivative of the function and the second derivative and their roots indicate the function’s increasing and decreasing intervals and its graph. This representation is very systematic and it acts like a method to draw the function’s graph with no-fault possible. Yet, besides being used for many years, is still used for courses like Calculus, etc. We argue that cognitive overload theory cannot alter this representation due to its systematic nature. In content analysis, some examples of this representation are shared via the reader, and some qualitative aspects about it are analyzed. Finally, its systematicity, well-structured nature, and nature in reducing extraneous cognitive load are emphasized. The important thing here is that it is very strategic not to lose some representations for the sake of new ones if their value is already known but not discussed too much.

Abstract

Mathematics teaching aids play an essential role in the learning process, where these aids become a bridge in the transfer of knowledge between teachers and students. The good of mathematics learning media will affect the process of transfer of knowledge from teacher to student. Therefore, this study aims to analyze and describe the quality of mathematics teaching aids developed by pre-service mathematics teachers in Indonesia, specifically from pre-service mathematics teachers in the Mathematics Education Department of Universitas Muhammadiyah Surakarta. This study uses descriptive analytical studies in which the data obtained is analyzed quantitatively and described qualitatively. This study concludes that, in general, the quality of mathematical teaching aids developed has been categorized as at least "good enough" both in pedagogical and conceptual aspects, as well as in physical aspects. However, some points need notable improvement and attention by the teaching lecturers at the point of the level of quality of safety and the quality of the teaching's ability aids in providing stimulus to students.

Abstract

The study determined the predictive power of students’ misconceptions and difficult concepts in physics on academic engagement and retention. The study adopted a correlational survey research design. The population comprised 3148 science students in Benue State. The sample was 650 science students. Six research questions were answered and six null hypotheses were tested. The instruments for data collection were Physics Difficult Concepts Retention Test (PDCRT), Physics Academic Engagement Scale (PAES), and Physics Students’ Misconceptions Identification (PSMI). The PDCRT, PAES, and PSMI were faces validated and PDCRT was also content validated. An estimate of internal consistency was obtained through Cronbach’s Alpha for PAES and Kuder-Richardson (K-R21) for PDCRT. The coefficient of internal consistency was 0.73 for PAES and 0.88 for PDCRT. Regression analysis was used for data analysis. It was spotlighted that students’ misconceptions, as well as difficulty levels in Physics, significantly predicted academic engagement. However, students’ misconceptions, as well as difficulty levels, do not significantly predict retention in Physics. It was also found that students’ misconceptions and difficulty levels jointly significantly predicted students’ academic engagement in Physics. Similarly, the combination of students’ misconceptions and difficulty levels significantly predicted retention in physics. It was recommended among others that Physics teachers should use instructional strategies that allow self-directed learning that could give emotional safety, reduce misconceptions and enhance academic engagement. Physics teachers should guide students using systematic procedures so that they acquire relevant skills essential for successful learning interplay to reduce the level of difficulty in understanding Physics concepts and enhance retention.

Abstract

This research is in the form of experimental research. The purpose of this study was to examine and see the effect of applying the ASSURE model and prior knowledge on the results of Simulation and Digital Communication subjects at the SMK. The population involved in this study were students majoring in Computer and Network Engineering class X SMKN 3 Pariaman, where class A was the experimental class and class B was the control class. These two classes were also divided into two groups, high and low prior knowledge. This study uses a 2x2 factorial design. Hypothesis testing using two-way ANOVA test. The results obtained are that (1) the learning model has a significant effect on learning outcomes, the ASSURE model gets a higher score than the conventional learning model, (2) prior knowledge has a significant effect on learning outcomes, higher prior knowledge gets a higher score than the conventional learning model. which is low, and (3) there is no interaction between the learning model and prior knowledge on learning outcomes. The N-Gain test showed that high prior knowledge in the ASSURE learning model got the highest improvement results and low prior knowledge from conventional classes got the lowest results.

Abstract

Online learning has been implemented for more than two semesters, amid the problems of 'stuttering' technology, lecturers and students complained about the declining quality of learning and student participation. The purpose of this study was to determine the effectiveness of the implementation of online learning in the Economic Education study program at Ivet University and its effect on student learning participation. The research sample is 50 students. They were collecting data using questionnaires and interviews. The data were analyzed using an eclectic approach, combining regression and qualitative techniques. The results showed: 1). The effectiveness of the implementation of online learning with an average score of 3.81 in the high category 2). Student participation in online learning with a mean score of 4.0 in the high category and 3). Testing the hypothesis with regression techniques obtained the regression equation Y = 38.370 + 0.309.b + e, coefficient F = 4.730 with a significance of 0.035 0.05 and R Squares = 0.090. Conclusion: online learning affects the learning participation of students in the Economic Education study program at Ivet University.
