Testing is the most common way to assess student learning at all ages and grade levels. Testing is traditionally viewed as a measure of knowledge, and not as a way to enhance learning. Nonetheless, a large body of literature demonstrates that testing is actually an effective way to facilitate learning and enhance long-term memory for information. This finding, that retrieval of information from memory leads to better retention than re-studying or re-reading the same information, has been termed the testing effect. The benefit of testing compared to review of material is typically seen after a delay between practice and final test, with review being a better strategy when the test is given immediately or after a short delay. This phenomenon has been shown across a variety of contexts, test formats, retention intervals, and ranges of ages and abilities. However, one domain in which the testing effect has not been shown to work is in the review of student-produced lecture notes. Lecture note-taking is a ubiquitous learning strategy and notes have been shown to be highly correlated with academic outcomes such as test performance and GPA. Note-taking in itself is a cognitively demanding process, and students often struggle to take accurate and complete notes from lecture, thus limiting the benefits of note-taking and review. There is limited research on ways to improve the review function of notes. Thus, this dissertation sought to understand the effect of integrating the testing effect into the context of lecture note-taking on memory for information compared to review of notes and a lecture-only control. A sample of 59 high school students watched a video lecture and took notes on the information. The lecture was divided into three sections with two-minute pauses in between each segment. During each pause, students were asked to either reread their notes from the previous section (review group), recall and write down what they remembered to be the most important ideas from the lecture they were just shown (self-testing group), or complete a distractor word search puzzle for the duration of the pause (lecture-only control group). Participants were given a written recall test of lecture information following a one-day delay. Comparisons were made between lecture groups on test performance and note quantity. Measures of sustained attention and mind-wandering during lecture were examined as covariates. While participants in the self-testing group scored higher on the written recall test, this difference did not reach statistical significance. Self-testing and reviewing notes during lecture pauses were both significantly better than lecture note-taking alone. Results also showed that it was actually the students in the review group who took significantly more notes than those in the lecture-only control. There was a main effect for time, indicating that students in all lecture groups took increasingly more notes as the lecture progressed. Note quantity was found to be a significant predictor of test performance. Examination of attentional variables showed that students who reported lower instances of mind-wandering took significantly more notes and did significantly better on the recall test. Further, students in the self-testing group reported less of an increase in mind-wandering as the lecture progressed compared to those in the control group. Differences between the results of this study and other studies in the testing effect literature are hypothesized to be due several factors, including complexity of lecture information, encoding difficulties, and the presentation of new information at each self-testing time point. Future research should continue to explore the testing effect in conjunction with note taking.

As distance learning evolved, course designers and teachers quickly recognized the value of integrating online features into the classroom. The result was blended learning, a combination of online and face-to-face components. This complex and dynamic new form of education has raised many questions about the role of computer-mediated communication in education and has provided new opportunities for extending research in learning and communication. The purpose of the study was to determine whether a blended class will produce different (and possibly better) results in terms of student perceptions of the overall learning experience and student satisfaction than traditional lecture-based face-to-face instruction or learning that is delivered entirely online. The main goals of this study were to compare the effectiveness of face-to-face, online, and blended instruction, and to examine the role of interactions in the effectiveness of each educational method. While each form of instruction received very positive feedback from both students and instructors and the newly introduced blended courses proved very successful in terms of overall satisfaction with the learning experience, the traditional lecture-based courses produced more positive attitudes toward the subject matter. The possible causes of these discrepancies between some of the quantitative and qualitative results point toward the role of previous experience with online learning, cognitive development, and learning styles.

The purpose of this study was to assess the achievement of older learners when using computer-assisted-instruction tutorials with no time limits and to compare this achievement with that of other older students who were taught by the conventional lecture method of instruction. The effects of prior formal education, physical limitations, socioeconomic status, and sex were also identified. Students in the age categories fifty-five to sixty-seven and sixty-eight and over were placed at random in either a control group that would receive instruction in the conventional lecture method or a treatment group that would receive computer-assisted-instruction. Each of the students in the study completed a demographic data form, received instruction, and was tested over the topics which had been covered. The test scores and demographic data were summarized and analyzed using two-way analysis of variance. The purpose of the analysis was to determine (1) if there was a significant difference in the effectiveness of the two methods of instruction, (2) if there was a significant difference in the performance of the two age categories, (3) if there was a significant interaction between the age levels and the methods of instruction, and (4) if the test scores were affected by past formal education, physical limitations, socioeconomic status, or sex. It was determined that students in the computer-assisted-instruction groups scored as well as those in the conventional lecture method of presentation groups. There were no significant effects from past formal education, physical limitations, socioeconomic status, or sex. However, there were trends in the data that warrant further study. It was recommended that educators be encouraged to use computer-assisted-instruction tutorials when working with older students. CAI was found to be at least as effective as the more conventional lecture method, and the growth and expansion of computer technology makes this a viable option for future educational programming.

Promising results from the use of problem-based learning (PBL) as a teaching method in medical programs have encouraged many institutions to incorporate PBL into their curricula. This study investigates how applying hybrid-PBL (H-PBL) in a microbiology laboratory impacts students' higher-order thinking as compared to applying a lecture-based pedagogy. The experimental design compared the learning outcomes of two groups of students: the control group and the H-PBL group, for whom PBL cases comprised 30% of the curriculum. Both groups were taught basic skills for the microbiology lab by the same instructor. Using the traditional teaching style for the control group, the instructor offered each student what they needed for their experiments. The H-PBL group practiced experimental design, data analysis, theory proposal, and created research questions by using six study cases that were closely linked to the area of study. The outcome was measured using a pre- and post- assessment consisting of 24 questions that was designed by following Bloom's taxonomy of learning levels. A one-way ANOVA was used to analyze the data. The results showed that for the first three levels of Bloom's taxonomy— knowledge, comprehension, and application—there were no statistically significant differences between the H-PBL and control group gain scores as determined by a one-way ANOVA. For the knowledge level, f (1, 78) = .232, and p = .632; for the comprehension level, f (1, 78) = .004, and p = .951; and for the application level f (1, 78) =. 028, and p =.863. On the other hand, the gain scores for the three higher levels—analysis, evaluation, and creativity—improved for the H-PBL group. The analysis level showed statistically significant differences, with f (1, 78) = 4.012, and p = .049. Also, there were statistically significant differences in students' performance at the evaluation level, with f (1, 78) = 11.495, and p = .001, and the creativity level, with f (1,78 ) = 23.432, and p = .000. In conclusion, the study results supported the value of incorporating hybrid problem-based learning (H-PBL) into the traditional microbiology laboratory curriculum.

The study investigated the Impact of Activity-Based Teaching Method (ABTM) on students’ academic performance in basic science at Junior Secondary Schools in Katsina Metropolis, Nigeria. Three research questions and three research hypotheses were formulated to guide the researcher in the conduct of the research. The study randomly sampled three hundred and thirty (330) out of nine thousand and six (9,006) Junior III Basic Science Students. Three of the randomly selected schools were placed as experimental control groups. A total of one hundred and sixty five (165) students were randomly sorted out, each way, to constitute the experimental and control groups. A quasi-experimental pre-test-post-test research design was used for the study. A pre-test was administered to ascertain the equivalence of the two groups. The study subjects in the experimental group were taught a number of concepts enshrined in environmental management for sustainability using the assets in activity-based teaching method; the control group was taught the same content using the lecture method for eight weeks. The students were subjected to “Basic Science Achievement Test” (BSAT); this instrument provided data for addressing the research questions and hypotheses raised in the study; the hypotheses were tested using SPSS version 20.0 packaged at 0.05 level of significance; t-test for independent samples was used to test the hypotheses. The study revealed that basic science students taught using activity-based teaching strategy performed significantly higher than their counterparts who were only taught using lecture method; similarly, there was significant difference in the academic performance of males, as compared to female students; similarly the students exposed to activity-based teaching strategy demonstrated a higher retention ability indices in the learning of basic science concepts, as compared to their colleagues who were exposed only to the lecture method. The study recommended that teachers should employ activity-based teaching methodology (ABTM) in teaching concepts in basic science at Junior Secondary Schools in order to enhance academic performance and retention of the content that was taught. The study further recommended that there should be provisions in schools of facilities, provisions and equipment which are vital for effective implementation of activity-based teaching method (ABTM). / Curriculum and Instructional Studies / D.

This study focuses on perceptions of a group of Computing lecturers at a large post ’92 Scottish university of the changes that have occurred in the student body. It also considers whether or not the changes have had any impact on the identity and role of the lecturers and whether the lecturers have adapted their practice to accommodate the needs of the diverse student population. An empirical approach was used consisting of semi-structured interviews with a targeted random sample of lecturers. The findings indicate that the impact of the changes which have taken place within higher education have not been uniform and have varied depending on the perceived status of the institution as well as the discipline within the Higher Education (HE) hierarchy. The findings identify a number of areas for consideration by university managers, lecturers and higher education researchers. There appears to be a gap between university policies on widening access and student retention and the implementation of the policies by the lecturers. The findings show that the lecturers are aware of the greater diversity of the student body, but that many of the lecturers share the traditional view of a university student and therefore expect the students to adapt to fit the existing system rather than considering changing their approaches to suit the students. The lecturers in my study have adopted a number of strategies to cope with the constant changes taking place within higher education. However, many of them are unclear as to what is expected of them and unsure about how they should prioritise the numerous demands on their time. This study differs from and complements other work because it focuses on the lecturers’ perceptions of the changes in their role as well as in the student body. The outcome of my study is a better understanding of the perceptions lecturers have of their role and the students that they teach. Although my study is small scale and specific to a particular academic discipline within a large university, the findings should be of value not only to the particular institution in the study, but the wider academic community as well.

The research study was conducted to investigate the effectiveness of the instructional methods, particularly the lecture-discussion instructional method as a teaching and learning method at grade 7 level, in Shurugwi district, Zimbabwe. The subject taught being English language. The experimental method (quasi-experimental) used at the twenty chosen schools was the pre-test and post test group method. It was found that the lecture-discussion instructional method produced better results in more cases than the discussion method alone. It was also found that work produced by the lecture-discussion instructional method was more refined than work produced by the discussion method alone. Guided learners were more work focused than learners discussing alone without a teacher. Average and below average learners did not enjoy learning without the presence of the teacher talk. The learners, during teacher absence, seemed hesitant and confused at times. The lecture-discussion method seems to cater for all the learners and their learning styles. The importance of the teacher in the class was clearly demonstrated by the work and results produced by the learners at the twenty selected primary schools in Shurugwi district, Midlands province, Zimbabwe. All the learners that received treatment from the experiment produced better results than their control groups that did not receive the treatment. However, conclusions and generalisations can not be made because the samples used and the areas covered were too small in size. The learners studied were too few to make meaningful generalisations and conclusions for the country. Further researches should be carried out in future. / Curriculum and Instructional Studies / M.

The problem that guided this study was a socio-constructivist view of education via online learning. Based in the extant literature, a deficiency existed that directly correlated online learning closing the academic achievement gap between student populations. In other words, schools invested in technology; however, few empirical data sets existed that established a connection between technology integration and the academic achievement of different student groups. The purpose of this pooled regression analysis study was to determine whether the method of class instruction effected academic achievement gaps between three subpopulations based on gender, race, and SES. Specifically, this study examined whether gender, race, and SES could predict semester grades within and across traditional, blended, and online course instructional methods. The dependent variable for this study was student success in the form of an end-of-unit test grade designed to evaluate student understanding of the curriculum. The independent variables included student gender, ethnicity, and SES. Quantitative data were collected through an analysis of Public Education Information Management System (PEIMS) data and student end-of-unit exam grades. The research suggests one combined interaction, [gender x race] in the traditional learning environment, is statistically significant while several independent interactions are significant. Those independent interactions are TAKS scores, gender, and Socio-economic status. According to the trends in this research, no significant differences exists in academic achievement between African American males and White males enrolled in traditional, blended or online classes. This non-significance is important. As suggested, when all other external factors, in this research, are held constant and the academic playing field is level, male students perform equally within the classroom, also, because no significant differences exists in academic achievement, the quality of instruction from well-trained, highly qualified educators can be an integral factor in closing the achievement gap between African American, low-SES male students.

This qualitative study focused on four secondary school physics teachers in Bangladesh using semi-structured interviews and observations to explore their understanding about the relationship between practical work and developing students’ conceptual knowledge of physics. Recent studies indicate that practical work helps secondary science students easily and effectively learn the concepts and theories of physics. However, the secondary school physics teachers in Bangladesh in this study did not provide students with practical work during classroom teaching. Rather, they provided practical work in separate practical classes. Although the teachers believed that practical work made their teaching and also students’ learning easier and effective, they did not offer frequent practical demonstrations in teaching the contents of physics. The major findings of the study include that teachers used mostly transmissive pedagogy to assist students to understand physics concepts and theories. Even though there are clear and specific instructions for the teachers to do demonstrations in the secondary physics curriculum, there were constraints on teachers and on students trying to conduct practical work. Constraints included: a lack of sufficient equipment. Teachers and students in non-government schools faced comparatively more difficulties than those in government schools. Low teacher/student ratios and no positions for laboratory assistants were reasons given for teachers’ intense workloads. This study implies a need to provide government and non-government schools with necessary equipment for doing practical work; to appoint sufficient teachers with higher studies and training that includes practical work in physics; to create positions for laboratory assistants; to set up classrooms with a smaller number of students; and to develop awareness of the value of practical work among school administration and among physics teachers.
