Abstract

This research aims to develop an E-LKPD integrated with FlippingBook technology based on the Environmath approach, as well as to investigate the enhancement of students’ metaphorical thinking skills before and after the implementation of the developed instructional materials. The study utilized a Research and Development (R&D) methodology guided by the ADDIE model, which comprises five sequential phases: analysis, design, development, implementation, and evaluation. Data were gathered through observations, expert validations of both material and media aspects, and assessments of students’ metaphorical thinking abilities. The participants involved in this study included two material experts, three media experts, and twenty seventh-grade students from MTs Miftahul Falah Panumbangan. The findings revealed that during the analysis stage, a needs analysis, student analysis, and material analysis were conducted. In the design stage, test instruments were prepared, media and format were selected, and the initial product design was developed. The development stage includes the product development process, while at the implementation stage, E-LKPD was tested on students. Furthermore, at the evaluation stage, it was found that there was a significant increase in metaphorical thinking skills after students used E-LKPD assisted by FlippingBook based on environmath with the quality of the increase being in the high category.

Abstract

This research aims to analyze the spatial abilities of students in light of Florence Littauer's personality types and understanding of how students personality traits can influence their mathematical spatial abilities. This research is a qualitative research with an exploratory method. Data were collected from eighth-grade students of SMP Negeri 13 Tasikmalaya, . The subjects of the research are eight eighth-grade students from SMP Negeri 13 Tasikmalaya from each representing each of the four personality types. The research instruments included a personality type questionnaire, spatial ability tests, and unstructured interviews. Data were analyzed through data reduction, data presentation, and conclusion drawing. The results indicate variations in spatial ability achievement according to personality type. Students with a melancholic type demonstrated comprehensive mastery of all spatial indicators, while sanguine and phlegmatic students showed strengths in spatial perception as well as some aspects of visualization and rotation, though they still needed reinforcement in using geometric terminology and image representation. Meanwhile, choleric students exhibited strong mental rotation skills but experienced difficulties in visualizing objects from multiple perspectives and assembling shapes after manipulation. These findings contribute to mathematics education theory by highlighting the role of personality types in developing students’ spatial thinking skills

Abstract

This study aimed to describe the profile of addition and subtraction performance and to examine the effectiveness of SIGMA-ToSM in improving arithmetic fluency of a slow learner student. The study employed a Single Subject Research design with an A-B-A pattern involving baseline-1, intervention, and baseline-2 phases. The participant was one grade VIII student at SMP Negeri 2 Cimerak who had been identified as a slow learner through teacher interviews, initial arithmetic testing, and psychological assessment with an IQ score of 73. Data were collected through repeated administration of the Test of Second Mathematics (ToSM) as the assessment instrument, SIGMA-ToSM as the structured intervention instrument, observation, interview, and documentation. The main indicator was Operations per Minute (OPM), representing accuracy and speed simultaneously. The findings showed that the mean addition score increased from 4.66 OPM in baseline-1 to 22.54 OPM during intervention and to 30.34 OPM in baseline-2. The mean subtraction score increased from 4.26 OPM to 14.37 OPM and then to 20.13 OPM. Visual analysis showed positive trends, stable maintenance at baseline-2, positive level changes, and 0% overlap between compared conditions. Observation and interview data also indicated better readiness, engagement, strategy use, independence, and confidence. These findings indicate that SIGMA-ToSM was effective in improving addition and subtraction performance of the slow learner participant, with stronger effects on addition than on subtraction.
