Abstract

This study determined the quality of games students perceived for the game-based materials they develop after they experience playing a mathematics gameboard. The participants in this study were 88 students in 11th-grade Senior High School composed of 40 students in Sohoton General Academic Strand and 48 students in Kanlanuk Technical-Vocational Livelihood, selected through convenience non-random sampling. Through created games by students, it removed the presence of boredom that improved their performance. It impaired other competencies such as retention and automaticity of information from long-term memory. Moreover, students have developed the competitive, cooperative, and meaningful characteristics of the games, which was considered helpful in improving their knowledge based on how they perceived its' characteristics are important to contain in the game, and their confidence to participate in the lessons. Results from the classical item and test analysis spreadsheet revealed that the prior knowledge of the students increased after the interventions were made and implemented. The characteristics of the game were considered helpful to improve students’ knowledge and confidence in the lessons. These results have implications for in-depth study and analysis to have conclusive results regarding the influence of the intervention in enhancing students’ creativity.

Abstract

The purpose of this study was to analyze students' understanding to solve arithmetic sequences and series questions. The subjects of this study were students who are in the 12th grade at SMAN 2 Garut, and they were 77 persons has been selected randomly from two study groups with the same teacher. This research applied descriptive quantitative techniques. The research result shows that students' ability is still low in solving arithmetics questions. This research found that there are three categories of students based on their achievement scores, namely the low category with a percentage is 42%, the medium category with a percentage is 36%, and the high category with a percentage is 22%. Some factors causing students’ errors are ineffective learning, uncarefully solving questions, and students have been lack of understanding of the material.

Abstract

The mathematics materials in learning mostly used package books, but the provided resources in the school were limited and teachers did not optimize the existing technology to provide effective and interesting materials. As a consequence, students did not complete the exercise according to mathematical procedures and they were pessimistic. The general research purpose was to produce a metaphorical thinking approach-based worksheet for students' procedural fluency on valid characteristics. This study used research and development by the ADDIE stage model. The participant was 9th-grade students in junior high school. Data collection were observation, questionnaires, and interview techniques. The results showed that the characteristics of the developed worksheet have been valid. The results of the worksheet validity test were obtained by 90% and the results of the trial of students were 93%. The implications of this worksheet are helpful for students to independent learning, and this worksheet helps students solve mathematical problems in accordance with procedural, assisted by steps of the metaphorical thinking approach, teaching and learning activities are more effective.

Abstract

The purpose of this study was to describe the development of valid, practical, and effective learning media on Geometry materials with worksheets equipment. This research type was development research using the modified Borg & Gall procedures by several main steps, namely product analysis developed, initial product development, and product trials. The product trials carried out consisted of two stages, namely expert validation was carried out to know whether the created learning media was suitable for use or not, from the validation results it was concluded that learning media could be used with slight revisions, then small-scale trials were carried out to find out college student responses to learning media by using college student response questionnaires and conducting tests (evaluations) to obtain media effectiveness data, while the results of the development of interactive mathematics learning media are valid with scores of 3.64 and 3.36, practical with a score of 3.83 and very effective with 90% complete mastery of the material.

Abstract

Smartphones have become handy tools in the hands of 21st-century teenagers owing to their necessity for communication and socialization. These devices could therefore possess underlying benefits for mathematics education. This quasi-experimental study probed the consequence of smartphone-assisted Jigsaw cooperative learning on senior secondary school students’ mathematics self-efficacy with recourse to how gender and smartphone efficacy could moderate this effect. The study involved five research questions and hypotheses. Two schools from the Educational District IV, Lagos State were selected by purposive sampling technique from which five hundred and thirty four (534) students drawn from intact classes were assigned into experimental and control groups. Smartphone Assisted Learning Package (SALP) served as the intervention while a valid and reliable Mathematics Self-Efficacy Questionnaire (r=0.90) was employed for data collection. Statistical tools deployed for descriptive and inferential analysis include mean, standard deviation and Analysis of covariance (ANCOVA). Outcome of data analysis portrayed a momentous effect of treatment on students’ mathematics self-efficacy. Smartphone efficacy and gender were found to possess substantial influence on participants’ mathematics self-efficacy. These findings led to the recommendation that teachers should expose mathematics students to smartphone-assisted Jigsaw cooperative learning strategy to promote active learning and improve students’ mathematics self-efficacy.

Abstract

This paper aimed to generate a theory that answers the question, “How do students cope with the challenges in learning mathematics in the normal? This study made used of the deductive axiomatic approach in theory generation following the steps prescribed by Padua (2012). Four axioms were formulated: (1) Students employ time management in studying math; (2) Students uses compensation strategies in overcoming challenges; (3) Students’ resourcefulness leads them to learn mathematics; and (4) Students asked help from teachers and peers in understanding mathematical concepts. Two propositions were derived from these axioms: students’ cope with the challenges in learning mathematics by (1) direct coping strategies support students’ resiliency in learning mathematics and (2) Indirect coping strategies indirectly provide support for coping strategies through planning, socializing with others and increasing empathy. From these propositions, the Students’ Mathematics Resiliency Based Theory is formulated: The Students’ Mathematics Resiliency Theory states that resiliency in learning mathematics is affected by both direct and indirect coping strategies. Direct coping strategies include compensation strategies, while indirect strategies include social, time management, and resourcefulness.

Abstract

Mathematics as an abstract subject, requires the application of cognitive strategies such as self-regulated learning skill to predict students’ achievement. This paper was designed to investigate the secondary school students self-regulated learning skill as a predictor of mathematics achievement with respect to gender. A correlational survey research design was employed. The sample size consisted of 882 senior secondary students class two (SSII) randomly selected from 14 out of 124 public senior secondary schools in Owerri Education Zone of Imo State. Two different instruments were used for data collection. They are Questionnaire on Self-Regulated Learning (QSRL) and Mathematics Achievement Proforma (MAP). Three experts validated the instrument. The Cronbach Alpha calculated yielded a reliability coefficient of 0.89 for QSRL. The data collected were analyzed using Pearson Product-moment correlation coefficient and regression analysis with the aid of Statistical Package for Social Sciences (SPSS) version 20. The findings revealed that self-regulated learning skills significantly predict male students’ achievement in mathematics. The findings also showed that self-regulated learning skill does not significantly predict female students’ achievement in mathematics. It was recommended among others that secondary school students should regulate their learning to increase their mathematics achievement.
