The STEM approach is a student-centred teaching and learning process that involves an inquiry process in problem-solving questions. This study was conducted to examine the effectiveness of the STEM approach in enhancing students’ mathematics performance. The study used a quasi-experimental design of unbalanced groups through the pre-test and post-test for treatment and control groups. The instrument included a set of questionnaires on student attitudes towards STEM implementation and the three-dimensional geometric shapes achievement test. The research samples included 14-year-old students from one of the private secondary schools in Kuching, which involved 68 students who were selected using purposive sampling. The results showed that student attitudes towards the implementation of the STEM approach were at a moderate level. In addition, the results illustrated a significant and moderate difference in mathematics performance between students who participated in the STEM approach and the conventional method using pre-test and post-test. The mean score of the post-test performance for the STEM approach was higher compared to the mean score of post-test performance for the conventional method. The results of the study demonstrated that the implementation of the STEM approach that involved both inquiry-based learning and problem-based learning was effective and able to improve the students’ academic performance. This can help teachers to vary their teaching and learning methods by increasing student interactions and engagement. Improvements can be made in the future by adding more research samples to expand the context of the study and prolong the treatment duration. Researchers can also add research variables in future studies by examining student interests and motivations towards the STEM approach.

<p>The Ministry of Education in Saudi Arabia has used technology to support teaching and learning in Saudi's school system to meet the requirements of the National Transformation Program under Vision 2030. There are different kinds of technology which can enhance the effectiveness of the teaching and learning of mathematics, such as the iPad. This paper presents results of primary research investigating the effect of using iPads in enhancing student achievement in a Saudi secondary school. A quasi-experimental design was used to determine the effect of using an iPad on students' achievement in mathematics across two tenth grade classes (A and B) for two months. In the first month, students of group A used the iPad as a learning tool (treatment group), while students of group B used traditional methods as learning tools (control group). In the second month of the quasi-experimental period, group A became the control group using traditional methods, while group B became the treatment group using the iPad to learn mathematics. At the start of the experiment, a pre-test was completed, and the first post-test occurred one month later, then the treatment was switched. After two months at the end of the quasi-experimental period, both groups had taken the second post-test. Cronbach's alpha coefficient measured the reliability of these tests, with the first test at 0.784 and the second test at 0.792, regarded as very high (close to 1.00). Thus, the tests' reliability and credibility were confirmed. Nine comparisons of the means were used to see if a significant statistical difference between the mean of the two groups or within a group existed, by using the SPSS t-test. After comparing the mean of ‘within-group A’, ‘within group B’, and ‘group A and group B’, it was seen that using the iPad made a statistically significant difference (p&lt;0.05) in students' achievements compared to traditional methods. The study summarises the main results and specific recommendations are provided.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0631/a.php" alt="Hit counter" /></p>

We aimed to contribute to a shift in higher education teaching and learning methods by considering problem-based learning (PBL) as an approach capable of positively affecting students from a geology and environment (GE) curricular unit. In a convenience sample from a Portuguese public university, two groups of students were defined: (1) an experimental group (n = 16), to which an intervention program (IP) based on PBL was applied, and (2) a comparison group (n = 17), subjected to the traditional teaching approach. For nine weeks, students subject to the IP faced four problem scenarios about different themes. A triangulation of methods was chosen. The study involved two phases: (1) qualitative (sustained on content analysis of driving questions raised by students, registered in a monitoring sheet) and (2) quantitative (quasi-experimental study, based on data from a prior and post-test knowledge assessment). The qualitative results point to the development of more complex cognitive-level questioning skills after increasing familiarity with PBL. The data obtained in the quantitative study, which included both a “within-subjects” and a “between-subjects” design, show higher benefits in the experimental group, documenting gains in terms of scientific knowledge when using the PBL methodology.

AbstractThis quasi-experimental study investigated the effect of teaching aesthetic skills to faculty members on development of their effective teaching performance through a two-group pretest-posttest design. The sample included 32 faculty members at a major Iranian university who were divided into the experimental (11 participants) and control groups (21 participants). The experimental group was taught to use aesthetic skills in the teaching and learning processes; however, no intervention was applied to the control group. To evaluate the effective teaching performance of the faculty members, a tailor-made questionnaire was used in two pretest and posttest stages, where randomly chosen students were asked to express their opinions about the faculty membersí performance. The sample size of the students was 1096 in the pretest stage and 935 in the posttest stage. Paired t-test results showed that there was no significant difference between the mean effective teaching scores of the faculty members in the control group in the pretest stage and in the posttest stage. However, the mean effective teaching scores of the faculty members in the experimental group were found to be significantly higher in the posttest. In addition, although there was no significant difference between the mean effective teaching scores of the two faculty groups in the pretest, faculty members in the experimental group outperformed their counterparts in the control group. Based on the findings, applying aesthetic skills by faculty members in the teaching and learning processes can pave the way for sustainable development of their effective teaching performance. Therefore, faculty members are recommended to acquire the required knowledge and skills to better use aesthetic skills in the teaching process.
