Effects of just-in-time inquiry prompts and principle-based self-explanation guidance on learning and use of domain texts in simulation-based inquiry learning

Although scientific inquiry with simulations may enhance learning, learners often face challenges creating high demand for self-regulation due to an abundance of information in simulations and supplementary instructional texts. In this research, participants engaged in simulation-based inquiry about principles of electric circuits supplemented by domain-specific expository text provided on-demand. They received just-in-time inquiry prompts for inquiry behaviors, guidance to self-explain electrical principles, both, or neither. We examined how these interventions influenced participants’ access of text information and achievement. Undergraduates (N = 80) were randomly assigned to one of four groups: (1) inquiry prompts and principle-based self-explanation (SE) guidance, (2) inquiry prompts without principle-based SE guidance, (3) principle-based SE guidance without inquiry prompts, or (4) control. Just-in-time inquiry prompts facilitated learning rules. However, there was no main effect of principle-based self-explanation guidance nor an interaction involving both interventions. Effects of just-in-time inquiry prompts were moderated by prior knowledge. Although principle-based self-explanation guidance promoted re-examination of text-based domain information, reading time did not affect posttest scores. These findings have important implications for instructional design of computer-based adaptive guidance in simulation-based inquiry learning.

A cooperative learning intervention for improving a simulation-based paediatric nursing course: A quasi-experimental study

AimThis study aimed to examine if a cooperative intervention improved outcomes for a simulation-based paediatric nursing course. BackgroundFostering cooperative learning can enhance student engagement and improve learning. Simulation-based courses provide nursing students an opportunity to practice and hone nursing skills when hands-on experiences are limited. Providing instruction in cooperative learning could improve course outcomes. DesignA quasi-experimental study with pre-test/post-test assessments. MethodsThird-year nursing students enrolled in an 18-week paediatric simulation-based nursing course were purposively recruited (N = 110). One class (n = 55) received a researcher-developed cooperative learning program, which encouraged student support during class activities and simulations. The second class (control) received usual class instruction and simulations. The efficacy of the intervention was assessed by comparing mean scores at class enrolment (pre-test) and completion (post-test) for self-perceived problem-solving attitude, cooperative learning experience and knowledge of paediatric nursing. Paired t-tests compared pre-test with post-test scores for the two groups. ANCOVA examined differences in mean scores between groups. Correlations between differences in mean pre-test and post-test subscale scores for problem-solving attitude and cooperative learning experience were also examined. ResultsThere was no significant difference in age or gender between groups. Mean post-test scores on the final exam were significantly higher for students who received the intervention (85.26, 95 % CI 84.19, 86.33) compared with controls (83.61, 95 % CI 82.52, 84.69; F = 4.63, p = 0.034). There were no significant differences in total scores for problem-solving attitude or cooperative learning experience or between groups. For the intervention group, two problem solving subscales were correlated with two cooperative learning subscales: problem solving confidence with learning motivation, respectively (r = 0.302, p = 0.025) and personal control with classroom learning, respectively (r = 0.389, p = 0.003). For the control group, approach-avoidance problem solving was negatively correlated with cooperative learning efficacy (r = −0.343, p = 0.01). ConclusionsCompared with the control group, nursing students who received the cooperative learning intervention had higher scores for knowledge of paediatric nursing, as well as learning motivation and attitude and problem-solving confidence, suggesting that the researcher-designed intervention facilitated simulation-based learning as well as confidence in problem-solving. Nurse educators could easily integrate the intervention into simulation-based paediatric nursing courses to enhance students' problem-solving abilities.

The Effectiveness of Communicative and Test-Focused Approaches in TOEFL® Preparation Classes

This study investigates the effectiveness of the Communicative Approach and the Test-Focused Approach in TOEFL® preparation classes. Sixty-four students from Islamic Senior High School Madrasah Aliyah Al-Insan (pseudonym) in Jombang, East Java, Indonesia, were divided into two groups: one receiving instruction based on the Communicative Approach and the other on the Test-Focused Approach. Using a quasi-experimental design, pre-test and post-test scores were analyzed to measure improvements in TOEFL performance. The results showed significant score increases in both groups. The Communicative Approach group’s mean pre-test score of 456 improved to 483 post-intervention, while the Test-Focused Approach group’s mean score rose from 460 to 493. The paired sample t-test results indicated statistically significant improvements within each group, with p-values of 0.00 for the Communicative Approach and 0.00 for the Test-Focused Approach. Additionally, the independent sample t-test revealed that the Test-Focused Approach group performed significantly better than the Communicative Approach group post-intervention, with a p-value of 0.030. These findings align with existing theories on language learning and test preparation, suggesting that while communicative methods enhance overall language proficiency, test-focused strategies more effectively boost immediate test performance. The study concludes that integrating both approaches in TOEFL preparation programs can provide a balanced and comprehensive strategy, optimizing both language development and test readiness. Future research should explore the long-term effects of such integrated methods on students' language proficiency and academic success.

Effectiveness of Word Games in Teaching Students Vocabulary

This study explores the effectiveness of word games as an effective tool for teaching English vocabulary to Grade 7 students at the University of Cebu-Main Campus during the 2016-2017 academic year. By comparing the performances, the pretest and posttest, of control and experimental groups, the research aimed to determine whether word games significantly improved vocabulary acquisition. The findings indicated that while both groups showed improvement, the experimental group demonstrated a more substantial increase in posttest performance, suggesting that word games can enhance vocabulary learning. A researcher-developed questionnaire was used as the assessment tool. Despite these promising findings, several limitations were noted, including the focus on a single group of students within one academic year, the small sample size, and the exclusion of factors such as student motivation and teaching styles. The reliance on pretest and posttest scores also limits insight into long-term retention. Nevertheless, the results provided a basis for proposing an action plan to enhance vocabulary instruction through word games.

The Development of Non-Formal Learning Organization Skills in Preservice Math Teachers

Although the effects of out-of-school learning on students' learning have attracted significant attention among education researchers in science and social sciences, little is known about the development of pre-service elementary mathematics teachers' skills in utilizing out-of-school learning in mathematics lessons. The aim of this research is to investigate the impact of activities conducted within the scope of the out-of-school learning environments in mathematics education on pre-service elementary mathematics teachers' skills in organizing non-formal learning. The study utilized a sequential explanatory design, which is a mixed-method approach. The quantitative part of the research employed a "single-group pretest-posttest design without a control group" from experimental designs. This study involved 35 third-year teacher candidates enrolled in the Primary Education in Math Program (PREDMAP) at a state university located near Ankara, the capital city of Turkey. The data collection instrument used in the study was the Out-of-School Learning Regulation Scale (OOSLRS). Additionally, teacher candidates were asked to write reflective essays about their thoughts on the program at the end of the study. The analyses revealed that prior to the program, pre-service math teachers had the highest scores in the knowledge dimension and the lowest scores in the implementation dimension of organizing out-of-school learning. Significant differences were found in the pretest scores of preservice math teachers only in the knowledge dimension based on their previous experiences in organized out-of-school learning environments during their educational lives. Significant improvements favoring the post-test application were observed across all dimensions between pretest and posttest scores. Data from reflective essays written by the preservice math teachers indicated their emphasis on active participation and included suggestions particularly in the implementation dimension.
