Development of a scientific attitude measurement instrument for Dharmacariya department students at STABN using the Fishbein and Ajzen model
No full textThis study applies the Fishbein and Ajzen model to develop a Scientific Attitude Measurement Instrument for Students, focusing on attitudes, beliefs, and intentions towards scientific behaviors. The quantitative research employs an instrument development method, initially constructing dimensions reflecting various scientific attitudes such as attitudes towards the scientific method, collaboration, openness to knowledge, criticality, respect, honesty, independence, and interest in data analysis. The instrument measures students\u27 scientific attitudes across three main dimensions: attitude, subjective norms, and behavioral control, aligning with the Fishbein and Ajzen model. It covers key aspects like attitudes towards the scientific method, emphasizing rigorous approaches like Popper\u27s Falsification concept, and the importance of social interaction in scientific collaboration. Validity and reliability analyses confirm the instrument\u27s adherence to high-quality standards, making it relevant for assessing scientific attitudes and contributing to educational quality and student development in science. It provides a comprehensive view of students\u27 perceptions and responses to scientific attitudes. Factor Loadings in the Rotated Component Matrix, with loadings above 0.50, indicate a strong correlation within the model. Cronbach\u27s Alpha values range from 0.922 to 0.941, ensuring internal consistency and reliability. Exploratory Factor Analysis with student participants established the construct\u27s validity and reliability, with a Kaiser-Meyer-Olkin (KMO) value of 0.747, indicating suitability for factor analysis. Most items showed high analytical validity, but items B22 and B13 require further review or adjustment
Effects of Mind Mapping And Visual Imagery Instruction Strategies on Senior Secondary Schools Students\u27 Scientific Attitude to Mechanics in Ekiti State of Nigeria
No full textThe study examined the effects of visual imagery and mind mapping strategies on physics students\u27 scientific attitude to mechanics in Ekiti state, Nigeria. The study adopted 3 X 1 pretest-posttest control group quasi experimental research design. Eight senior secondary schools were be purposively selected for the experimental groups, while four schools were purposively selected for the control group. This made a total of twelve schools that were selected from twelve local government areas across all the three senatorial districts of Ekiti state for the study. A total number of two hundred and forty six physics students from the selected schools were used. The instrument that the researcher used for the study was self-designed instruments titled: Students\u27 Scientific Attitude to Mechanics. The data collected were analysed using descriptive statistics (mean, standard deviation) as well as inferential statistics such as Analysis of Covariate (ANCOVA) which was used to determine the significant mean and interaction effects to the variables of the study. Estimated Marginal Mean (EMM) was used to determine the performance of each group. Bonferroni pair wise and Scheffe Post-hoc analyses were also employed to trace the source of observed significance among the groups. The finding of the study revealed that there was significant effect of treatment on students\u27 scientific attitude to mechanics. The result further showed that those exposed to visual imagery had the highest scientific attitude mean score, closely followed by those exposed to mind mapping while those taught with conventional method of teaching had the least. Also, the finding of the study showed that there was significant main effect of gender on students\u27 scientific attitude to mechanics. Similarly, the finding showed that there was significant interaction effect of treatment and gender on students\u27 scientific attitude. Based on these findings, it was therefore recommended that mind mapping and visual imagery instructional strategies should be used in improving students\u27 scientific attitude
The effect of climbing and descending stairs varies in improving balestra fencing floret/foil weapon type
No full textFencing is a sport that requires a maximum physical component so that in this study the aim was to test and find out the effect of variations in stair climbing exercises in improving floret/foil balestra fencing weapons. This study used a test-experiment with the research design Single-Group Pretest-Posttest Design . The research sample consisted of 20 people, coming from students (elective course (MKP) Fencing) of a state university in eastern Indonesia (male and female) who were then divided into training groups through random sampling technique. The balestra fence measurement tool for floret/foil type weapons uses the Kuhadja fencing skills test. Pretest and posttest results were analyzed using the influence test (t-test). The research location is at the Football Stadium (a stadium grandstand with 25 steps). Results; 1) there was a significant difference between the pretest and posttest groups with the various stair climbing exercises towards increasing the ability to balestra floret fencing weapons. 2) There is a significant difference between the posttest (after treatment) of varied stair climbing training and the control group in increasing the ability to balestra floret fencing weapons. We estimate that this increase is the result of increased leg muscle strength, speed, and explosive power obtained through varied stair climbing exercises
Performance Analysis of EMG Signal Classification Methods for Hand Gesture Recognition in Stroke Rehabilitation
No full textThis study evaluates the performance of different classification methods in classifying healthy individuals and stroke patients. The hand gesture variations of the subjects were also analyzed based on electromyography (EMG) signals. Several classification methods were tested in this analysis to find out which method had the most suitable performance. The results showed that Decision Tree and Naive Bayes classifiers achieved the highest performance in classifying EMG signals from healthy individuals and stroke patients, with both methods showing high accuracy, precision, recall, and F1 score. Specifically, Decision Tree excelled in overall accuracy and recall, while Naive Bayes showed superior precision. For hand gesture recognition, SVM, KNN, and Random Forest classifiers showed similarly high performance, achieving accuracy, precision, recall, and F1 score above 82%. Naive Bayes also performed well, especially in precision, while Decision Tree performed poorly compared to other methods. This insight can form the basis for the development of more effective and personalized rehabilitation systems for stroke patients, by utilizing reliable and accurate EMG signal classificatio
Developing a religiosity scale for Indonesian Muslim youth
No full textThis study aims to construct and test the validity of the Islamic youth religiosity scale. The population in this study is Muslim students of senior high schools in Surakarta, Central Java, with a sample of 258 established using the random sampling technique. The data analysis used the Linear Structural Model. The result shows that the RMSEA (‰¤ 0.08) and GFI (‰¥ 0.09) values from the four dimensions (belief, ritual, social, commitment meet the standard values of compatibility with the respective values for RMSEA beliefs = 0.055 GFI = 0.94, RMSEA rituals = 0.026 GFI = 0.99, social RMSEA = 0.059 GFI = 0.91, commitment of RMSEA = 0.032 GFI = 0.97. This means that these dimensions (belief, ritual, social, commitment) can reflect the religiosity variables positively and fit empirical data. The most dominant dimension reflecting religiosity is the social dimension with an average factor loading value \u3e0.05, and the weakest one that reflects religiosity is confidence because many items have a loading factor \u3c0.05
Dominant factors that determine college students completing studies in mathematics education study programs
No full textFailure to graduate on time is a problem for both the university and the students themselves. Beside the competencies possessed by students, many other factors affect the completion of student studies. This study aims to reduce the variables that really affect the completion of student studies. The approach of this research was survey research on students of the Mathematics Education Study Program at least in semester 7 (currently taking a final project course). There are 17 factors that determine the completion of student studies, namely achievement motivation, discipline, interest, intelligence, study habits, health, part-time work activities, organizational activities, curriculum, mentoring methods, student relations with lecturers, availability of books, internet facilities, family economic conditions, relationships with parents and family members, friends, and social environment. Data analysis was conducted using Principal Component Analysis (PCA) method to obtain the dominant factor. Based on the results of the study, four main factors that affect the completion of student studies are formed, namely: (1) the first factor: motivation and academic ability; (2) the second factor: activities and social environment; (3) the third factor: facilities and family; and (4) the fourth factor: thesis guidance. The four factors can explain the dominant factor in student study completion at 86.54%, with details of motivation and academic ability at 37.57%, activities and social environment at 26.34%, facilities and family at 15.21%, and thesis guidance at 7.42%

Employing teacher agency theory, this instrumental case study views projections as agentive when they are informed by the students\u27 ecological aspects (past and present), oriented to solve potential learning problems and improve learning outcomes. The study involved 84 pre-service teachers who were voluntarily asked to fill in a questionnaire, submit a lesson plan, and be interviewed. nVivo Pro was used to organize themes. The study indicates that the pre-service teachers, M=3.81, SD=.590, perceive that innovation in online ELT classes is closely related to the integration of information and technology. As a result, the students\u27 agentive projections were also oriented to solve technology and internet-based obstacles, added with innovative learning methods. The research findings may become important insights for the development of English teaching and learning in order to provide more capital for pre-service teachers creating ELT innovation in the future
The development of measurement instruments of Sharia students\u27 perceptions about Khilafah
No full textThis study aims to develop an instrument to measure Sharia students\u27 perception of the Khilafah. The research applied the ADDIE development research approach. The activity began with reviewing Taqiyuddin An-Nabhani\u27s books and articles about Khilafah to get the instrument construct (analysis). The next stage was to compile the grid and assemble the instrument items (design). The items of the assembled instrument were then assessed by 11 experts (development). The validated Instruments were then carried out with limited and expanded trials. The limited trial was conducted on 26 students at Universitas Islam Negeri (UIN) Salatiga, and the expanded trial was conducted on 227 Sharia students from Institut Islam Mamba\u27ul \u27Ulum (IIM) Surakarta, UIN Raden Mas Said, and UIN Salatiga. The experimental data were analyzed with CFA. The results indicate that the instrument construct consisted of seven aspects of measurement encompassing the essence, the function, the establishment, the power and sovereignty, the form of state and government, the Khilafah government system, and the constitution for non-Muslims. The measurement model meets eight model fit criteria, including AGFI = 0.84 (\u3e 0.8), chi-square/df = 1.459 (\u3c 2), RMR = 0.054 (‰¤ 0.1), SRMR = 0.056 (‰¤ 0.1), RMSEA = 0.045 (\u3c 0.08), NFI = 0.95 (‰¥ 0.9), NNFI = 0.98 (‰¥ 0.9), CFI = 0.98 (‰¥ 0.9), IFI = 0.98 (‰¥ 0.9). The instrument also has a good guarantee of validity and reliability. This is indicated by the loading factor value of each indicator above 0.4 and the composite reliability value of 0.95 (\u3e 0.7) so that the instrument can be used for further measurements
