The Impact

Science educators have developed a variety of assessment techniques to help students connect their scientific knowledge and bridge conceptual gaps. In chemistry, concept maps and creative exercises are the two notable assessments that have been implemented into multiple chemistry courses and indicated promising effects on students’ conceptual learning and connection-making between chemistry concepts. These two assessment techniques were usually implemented individually in research studies. Herein, we employed a quasi-experimental, mixed-methods approach to explore whether combining concept maps and creative exercises would reveal any synergistic effects for student learning of chemical equilibrium and acid–base chemistry in a college general chemistry course. In this study, student perceptions of the use of the two assessments were examined by open-ended surveys. Interestingly, students perceived creative exercises as an assessment technique while concept maps were viewed as a learning tool for studying or reviewing exams. Additionally, Students believed that concept maps assisted them in answering creative exercises, but not vice versa. The four study groups (control group, concept maps only, creative exercises only, and both concept maps and creative exercises) were compared through concept inventory pre and post-test questions. The results of an ANCOVA indicated that participation in the experimental groups did not significantly impact conceptual learning gains, as measured by the concept inventory post-test scores. However, focus group interviews indicated students from the experimental group that used both concept maps and creative exercises were able to provide more sophisticated scientific explanations for conceptual questions related to the topics of chemical equilibrium and acid–base chemistry. Implications of these research results, best practices for implementation of the two assessments, and future research are discussed.

In an effort to improve student conceptual understanding and help students better connect pre-existing knowledge to new ideas, a concept map assignment was implemented in a first-year college level general chemistry course. This implementation included a quasi-experiment that was carried out in discussion group recitation sections within a third-quarter general chemistry course. Students enrolled in a single section of the course were divided into two groups in which a concept map treatment was compared to a control group that completed short journal entries. Comparison of a concept inventory post-test using an independent samples t-test indicates students in the concept map treatment appear to perform better than the students in the journal control group (t = 2.34, mean difference = 0.844, p < 0.05). However, a multi-variable regression analysis in which the concept inventory post-test scores were compared between the treatment and control groups, while traits related to incoming academic preparation were held constant, suggests there was no significant difference in performance (unstandardized b = 0.222, p = 0.540). The quality of the students’ concept maps was also evaluated and correlated to student performance on the concept inventory, and it appears students who were better at concept mapping made greater gains in conceptual understanding (Pearson's r = 0.295, p < 0.05). When the relationship between the quality of concept mapping and concept inventory post-test was determined while holding constant covariates related to incoming academic preparation, the unstandardized B coefficient was positive, but was not significant at the p = 0.05 level (unstandardized b = 0.215, p = 0.134) This study does not provide unequivocal evidence that a concept map treatment leads to greater gains in conceptual understanding compared to a control population, or that students with better concept mapping skills performed better on the concept inventory instrument. Nevertheless, a template for implementing a concept map assignment in a large enrollment course is provided, and the results presented herein might prompt chemistry instructors to consider including concept map assignments in their instructional toolbox.

Abstract Background Active learning pedagogy has recently received a great deal of attention, and many universities have attempted to create student-centered learning environments to improve students’ academic success. The purpose of this study is to explore the impact of concept-point-recovery (CPR) teaching sessions as an active learning strategy on students’ perceptions of the learning environment, motivation, and academic learning outcomes in an electrical engineering course. To investigate the effectiveness of CPR sessions, students’ perceptions of learning and their performance were compared to those of students in a control classroom. Finally, students’ written comments on the course and instructor were explored in further analysis. Results The quantitative findings revealed that there was a significant change in students’ perceptions of learning after the CPR teaching sessions, and there was an increase in students’ perceptions and learning outcomes compared with those of the control group. In addition, the qualitative findings from students’ written feedback demonstrated that students felt that the instructor cared about students’ learning and success and that they had a positive learning environment. Conclusions CPR teaching sessions can be an alternative model for instructors to connect with students and create supportive environments to help students achieve academic success, which in turn promotes the satisfaction of students’ basic psychological needs and self-determined motivation. Therefore, increasing students’ engagement in their learning processes and making connections with students through CPR teaching sessions can facilitate improvements in students’ motivation and academic success. How this new active learning technique can be applied to higher education is discussed.

Abstract A crucial step in problem solving is the retrieval of already learned schemata from long-term memory, a process which may be facilitated by categorization of the problem. The way knowledge is organized affects its availability, and, at the same time, it constitutes the important difference between experts and novices. The present study employed concept maps in a novel way, as a categorization tool for chemical equilibrium problems. The objective was to determine whether providing specific practice in problem categorization improves student achievement in problem solving and in conceptual understanding. Two groups of eleventh-grade students from two special private seminars in Corfu island, Greece, were used: the treatment group (N = 19) and the control group (N = 21). Results showed that the categorization helped students to improve their achievement, but the improvement was not always statistically significant. Students at lower (Piagetian) developmental level (in our sample, students at the transitional stage) had a larger improvement, which was statistically significant with a high effect size. Finally, Nakhleh’s categorization scheme, distinguishing algorithmic versus conceptual subproblems in the solution process, was studied. Dependency of problem solving on an organized knowledge base and the significance of concept mapping on student achievement were the conclusion.

The study investigates the impact of IELTS listening strategy use on the reduction of listening test anxiety and on the listening performance of the IELTS test takers in light of the data of 80 participants on the pretest and post-test IELTS listening along with the participants' score on pre-anxiety and post anxiety scale. So, drawing on the instruments including a proficiency test, pre/post-test, anxiety questionnaire, materials for strategy instruction, the participants were randomly divided into two groups: Control Group and Experimental Group, each including 40 participants. As per the procedure, after tackling their pre-listening performance and pre-anxiety score, one group was treated with IELTS-Listening related strategies and the other group was not treated, but both were administered listening test. The results of the study indicated that those treated with IELTS strategy outperformed ( t (78) = 4.57, p = .000, r = .460 ) those receiving no listening-related strategy. Furthermore, the results of a t-test run on the post-test of the groups anxiety arrived at a statistically significant difference (t (78) = 5.77, p = .000, r = .547), representing that the control group outperformed the experimental group. Also, Pearson Correlation done for finding out a potential relationship between anxiety and listening performance indicated a negative and weak to moderate relationship ((r (78) = -.26, p = .020). The pedagogical implications of the study are in detailed argued.

Purpose The purpose of this paper is to examine the development of family protective factors in participants of Help Me Grow Utah (HMGU), a community-based system that promotes child development, seeks early detection of developmental delays, and links families to services. Design/methodology/approach In this paper, standard quasi-experimental survey design was utilized. HMGU and control group participants completed the FRIENDS Protective Factors Survey, which was slightly modified into a retrospective pre-test and post-test format to address previous survey concerns of response-shift bias, self-serving assessments, and family maturation. Participants were asked to respond to ten questions at present and then again from the perspective of two years previous. Findings Participants in HMGU had statistically significant increases in protective factor scores in all but one subscale, with dramatic increases in two subscale questions on knowledge of parenting and child development. Control group scores statistically increased in four subscales, albeit at lower rates than HMGU participants. Interestingly, control group scores on two subscale questions relating to child maltreatment risk were significantly lower on post-tests as compared to their retrospective pre-test scores. Research limitations/implications Participants in HMGU clearly increased in the development of protective factors. Replication of this study is recommended and the need for a control group in protective factor studies is imperative. Practical implications Findings from this study suggest that child services focused on enhancing knowledge of parenting and child development might also expect to improve protective factors. One-on-one care coordination with families seems particularly effective. The findings might also benefit other social programs as they utilize retrospective pre-test, post-test, and control groups in their evaluations. Originality/value HMGU is the first affiliate to utilize retrospective pre-test/post-test methodology, which can overcome confounding results attributable to response-shift bias. Also, the use of a control group affords inclusion of natural maturation in considering findings.

This research examines the effect of participation in an enterprise education program on perceptions of the desirability and feasibility of starting a business. Changes in the perceptions of a sample of secondary school students enrolled in the Young Achievement Australia (YAA) enterprise program are analysed using a pre–test post–test control group research design. After completing the enterprise program, participants reported significantly higher perceptions of both desirability and feasibility. The degree of change in perceptions is related to the positiveness of prior experience and to the positiveness of the experience in the enterprise education program. Self–efficacy theory is used to explain the impact of the program. Overall, the study provides empirical evidence to support including exposure to entrepreneurship education as an additional exposure variable in entrepreneurial intentions models.

The Impact

the purpose of the present study was to investigate the impact of teaching critical thinking skills on reading comprehension of Iranian intermediate EFL learners. A sample of 50 students from Arshia Language Institute in Ilam, Iran participated in this study. They were both male and female students who were selected among 80 students based on their performances on PET. The participants were randomly divided into experimental and control groups. First, the two groups were exposed to the pre-test of reading comprehension in order to evaluate their knowledge on reading before the treatment. Based on scores obtained from the Pre-test, no significance differences were observed between two groups. After that the treatment was started and the experimental group was exposed to teaching critical thinking skills. Meanwhile, traditional methods of teaching reading comprehension were used for teaching reading comprehension to the control group. Finally, post-test of reading comprehension was delivered to both groups at the end of treatment to check possible differences.  To analyze the collected data, ANCOVA was run using SPSS Software Version 16. The results showed that teaching critical thinking skills positively affect reading comprehension of intermediate EFL learners, but the interaction of gender and teaching critical thinking was not significant.

The Impact

This article presents the results of a study examining the effectiveness of written corrective feedback (CF) on the simple past tense and the impact beliefs may have on students’ uptake of the feedback they receive. A seven-week study was carried out with 42 advanced EFL learners in Vientiane, Laos. Students’ beliefs about written CF were first collected, after which they were assigned to either the control group or to groups that received written CF according to their feedback preferences. Students produced four pieces of writing (pre-test, post-test and two delayed post-tests) that responded to four different narrative prompts. The targeted grammatical feature was the simple past tense. The study found that the three feedback groups showed significant improvement in the use of the targeted feature while the control group did not. Furthermore, the results seemed to indicate that beliefs might have impacted on the extent to which the Lao students improved their linguistic accuracy because the students who received their preferred type of feedback were more successful at eliminating the targeted errors than the ones who did not.

This journal aims to find the impact of tablet use on students’ mastery of grammar skills. In order to answer the research questions, the authors held the pre-test and post-test for two groups labelled as the experimental group and control group. The experimental group is the groups that using tablet, while the control group is the group that using textbooks in learning grammar. The results of this study show that there is no significant difference between the grammar achievement scores of the students in both groups. The findings also show that the instructor emphasized the influence of tablet use on learner autonomy, digital distraction, and network connection. Students indicated that tablets can be supplementary yet it shouldn’t replace the basic course materials such as textbooks and workbooks.
