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.

This study investigates the effects of problem-based learning (PBL) on students' academic achievements in studying ‘Electrochemistry’ within a course on Analytical Chemistry. The research was of a pretest–posttest control group quasi-experimental design and it was conducted with second year students in the Chemistry Teaching Program at the Faculty of Education at Dokuz Eylul University. The topic was taught with PBL in the experimental group and with expository teaching strategies in the control group. The ‘Chemistry achievement test (CAT)’ was applied as the pre-test and post-test in both groups. Post-test scores from the CAT demonstrated that there was a significant difference between the academic achievements of the two groups in favour of the experimental group (U= 8.500,p< 0.05). After using PBL for a period, eleven open-ended questions related to the topic were asked to both groups. The results of these questions were categorized and the scores obtained from the categories were evaluated using content analysis. The results of the scores obtained from the open-ended questions showed that the students in the experimental group were able to make statements containing fewer misconceptions and also had a better understanding of this topic when compared to the students in the control group (U= 2.500,p< 0.05). The correlation between the scores in the CAT post-test and the scores obtained from the open-ended questions of the experimental and control groups was also examined. The Spearman correlation coefficients were found to be 0.907 and 0.595 for the experimental and the control group, respectively. This finding indicated that there was a positive and very high level of statistically significant correlation between the scores in the CAT post-test and the scores obtained from the open-ended questions of the students in the experimental group. Therefore this finding also supports the conclusion that the students in the experimental group were better able to understand the topic and its structure compared to the students in the control group. At the end of the application, the results of semi-structured interviews carried out showed that students in the experimental group had positive opinions regarding PBL.

Introduction. The English language is a mandatory subject in elementary, secondary, and higher education in Ecuador. To become proficient, a broad knowledge of grammar is needed because it is considered the backbone of a language. Objective. This research aims to implement graphic organizers in the teaching-learning process of grammar tenses. Methodology. This inquiry took place at a university of Riobamba with a target population of 62 A2 level students. A quasi-experimental research, was carried out with 31 students that were the experimental group and the same number of students as the control group. A pre-test was applied to both groups to evaluate their grammar skills. After that, both groups were given a post-test to determine if the graphic organizers implemented made any improvement on the students’ performance regarding grammar tenses. Results. The post-test results demonstrated that the competence of the experimental group students has been enhanced after implementing graphic organizers. Conclusion. The students were able to clear up their ideas and to establish better relationships between graphical and cognitive demands.

Ghana abounds in indigenous resources but little mathematics has been conceptualised. The study therefore applied the four trends of real mathematics education on five main Ghanaian indigenous materials. The design was quasi-experimental non-equivalent groups of experimental (80) and control (70) students. The experimental group was taught with the four trends and the control with the traditional approach. The researcher used teacher-made test instruments through the standard psychometric techniques and tagged them as pretest and post-test scores. Both tests were similar and given to both groups before and after the treatments. The results show that the main indigenous Ghanaian materials were signs/symbols, artefacts, instruments, tools and technologies, and signs/symbols being the most significant. These results were then applied to the teaching and learning of mathematics at the senior high school levels. The researcher therefore recommends that students should be allowed to use indigenous mathematical ideas, concepts, generalizations and thoughts processes

El proceso de enseñanza y aprendizaje está muy determinado por la motivación y el ambiente de aprendizaje. La motivación y el ambiente de aprendizaje, dentro de la educación, dependen mucho de las metodologías educativas que se implementan en los centros educativos. El objetivo de este trabajo es comparar la motivación y el estado de Flow entre la estrategia metodológica Flipped Classroom y una metodología tradicional. Para ello se llevó a cabo un estudio de diseño cuasiexperimental, con selección de la muestra no probabilística e intencional. 103 alumnos universitarios participaron en el estudio, divididos en un grupo experimental (Flipped Classroom) y un grupo control (metodología tradicional). La motivación y el estado de Flow se evaluaron antes de comenzar la impartición de lecciones relacionadas con la asignatura: “Didáctica de la Educación Física” y al finalizar la misma (cuatro meses). Se utilizaron los cuestionarios de metas de logro 2x2 (Guan et al., 2006) y DREEM (Herrera et al., 2015). Para determinar si existían diferencias iniciales y finales entre los grupos se realizó la prueba T-Student de muestras independientes. Para observar las diferencias intragrupo (pre vs pos-test) se utilizó una prueba T-Student para muestras relacionadas. Los resultados muestran que existen diferencias significativas entre el grupo de control y el grupo experimental en las variables aproximación/maestría (p < .001), enseñanza (p = .003) y aprendizaje (p = .05). Con la metodología Flipped Classroom el alumnado presenta niveles en la motivación y en el estado de Flow superiores al alumnado que imparte una metodología tradicional.  Summary. The teaching and learning process is highly determined by motivation and the learning environment. The motivation and the learning environment, within education, both of them depend a lot on the educational methodologies that are implemented in educational centers. The objective of this work is to compare the motivation and the state of Flow between the Flipped Classroom methodological strategy and a traditional methodology. For this reason, a quasi-experimental design study was carried out, with a selection of the non-probabilistic and intentional sample. 103 university students participated in the study, divided into an experimental group (Flipped Classroom) and a control group (traditional methodology). The motivation and the state of Flow were evaluated before the beginning of the lessons related to the subject: "Physical Education Didactics" and at the end of it (four months later). The 2x2 achievement goal questionnaires (Guan et al., 2006) and DREEM (Herrera et al., 2015) were used. To determine if there are initial and final differences between the groups, the T-Student test was performed on independent samples. To observe intra-group differences (pre vs. post-test), a T-Student test was detected for related samples. The results found that there are differences between the control group and the experimental group in the variables approach/mastery (p < .001), teaching (p = .003) and learning (p = .05). With the Flipped Classroom methodology, students have higher levels of motivation and Flow status than students who teach a traditional methodology.

This study aims to investigate the effects of scientific calculators on mathematics achievement in support of problem-solving instructions. In this study, 49 low achieving mathematics students aged 14 years were selected from a secondary school in Kajang, Selangor, Malaysia. A pre-test post-test quasi-experimental design with two groups was employed in this action research study. The experimental group learned solid geometry and statistics topics, with the aid of a scientific calculator; while the control group did not use any technological aid to learn these topics. By controlling the pre-test score, the ANCOVA two-way test was applied to the post-test results. A positive significant difference was reported in favour of the experimental group. However, no significant interactions were noted between group and gender. The analysis results indicate that the use of a scientific calculator in the integrated teaching and learning of mathematics helped the students improved their mathematics achievements. These findings have important implications in the educational setting, particularly for educators to support and facilitate low-achieving students in mathematics.

This study is motivated by the dearth of research in pragmatic instruction in Italian as a foreign language (IFL) with beginner learners. Based on the limitations in the way IFL textbooks present requests, instructional material was designed with the following objectives: to improve learners’ pragmalinguistic and sociopragmatic competences and to raise their awareness of request realisation across different contexts. The material, designed for a 60-minute pedagogical intervention, was then used in an Italian language school in Sao Paulo with five intact classes of beginner Brazilian learners of Italian. We implemented a pre- and post-test quasi-experimental methodological design, where three classes were randomly selected to serve as the experimental group, and two classes served as the control group. The data collected through written DCTs and simplified retrospective questionnaires revealed that the learners in the experimental group showed a more significant improvement in their socio pragmatic, pragmalinguistic and metapragmatic competence compared to the control group. These results suggest a positive effect of consciousness-raising activities on learners’ declarative knowledge in the short term.
