Who Benefits Most From Head Start? Using Latent Class Moderation to Examine Differential Treatment Effects

Head Start (HS) is the largest federally funded preschool program for disadvantaged children. Research has shown relatively small impacts on cognitive and social skills; therefore, some have questioned its effectiveness. Using data from the Head Start Impact Study (3‐year‐old cohort; N = 2,449), latent class analysis was used to (a) identify subgroups of children defined by baseline characteristics of their home environment and caregiver and (b) test whether the effects of HS on cognitive, and behavioral and relationship skills over 2 years differed across subgroups. The results suggest that the effectiveness of HS varies quite substantially. For some children there appears to be a significant, and in some cases, long‐term, positive impact. For others there is little to no effect.     

Can Personalized Nudges Improve Learning in Hybrid Classes? Experimental Evidence From an Introductory Undergraduate Course

A field experiment was conducted to investigate whether personalized e-mail reminders can improve study consistency and learning outcomes in an introductory-level undergraduate course. By randomly assigning whether nearly 300 students would receive occasional e-mail messages encouraging out-of-class study, we find that these reminders increased exam performance by 0.2 standard deviations. Using detailed information on the timing and duration of study effort, we find two distinct patterns explaining this increase. Reminders increased weekend study time slightly, and weekday studying remained constant although it was shifted approximately 2 to 3 hours earlier for those who received reminders. A follow-up survey corroborates these channels, and suggests a third mechanism: increased cognitive effort during study. These findings highlight the potential for low-cost behavioral interventions to improve student performance. (Keywords: e-mail reminders; personalized nudges; hybrid learning; higher education)     

Does Reflective Journal Writing Improve Course Performance?

Abstract. This study investigated whether a reflective journal writing assignment would improve students' course performance. A total of 166 students from undergraduate sections of a course taught by the same instructor over three semesters completed the assignment as part of their requirements. Students (N = 317) from five previous semesters of the same course taught by the same instructor, who were not required to complete the assignment, served as a comparison group. Intervention and comparison groups were comparable on a variety of variables including all assignments, excepting the journal assignment. The findings are interpreted within the context of factors such as students' study habits and motivation.     

Effects of a Value-Reappraisal Intervention on Statistics Students’ Motivation and Performance

The authors investigated the effects of an exploratory value-reappraisal intervention on students’ motivation and performance in an undergraduate introductory statistics course. They sampled 82 students from 2 instructors’ sections during both the fall and spring semesters. Students were randomly assigned within each section to either the Value-Reappraisal (VR) or Control condition (C). VR presented messages about the importance of statistics and guided students in exploring potential values of learning statistics. Results showed positive effects of VR on task value, endogenous instrumentality, and a choice-behavior measure of interest. The authors found VR to affect exam performance, but only for students who had a particular instructor. This research helps broaden literature on self-regulation and expectancy-value models of motivation by focusing on the regulation of value perceptions.     

Reflection and its Place in the Curriculum on an Undergraduate Course: Should it be assessed?

In the fast changing world of health care the need for therapists to be reflective practitioners is no longer disputed. How reflection is taught and assessed at undergraduate level is however more contentious. This longitudinal study explores the experiences of students undergoing a number of assessments of reflection and also examines whether members of faculty have similar perceptions of those assessments. Analysis of data from focus groups and individual interviews suggest that students have a number of concerns about the assessment of reflection, some of which are shared by faculty. The paper concludes that the process of reflection is better left unassessed.     

Towards Student Self‐Direction in a First‐Year Undergraduate Physics Course

Summaries

English

This article describes a new physics course, developed for non‐science majors, which is largely based on student self‐direction. Problems of developing and implementing the course in the context of a more normal undergraduate study programme are identified and student reactions to the physics course are reviewed. Finally, some recommendations are made concerning the development and adoption of courses involving student self‐direction.     

The Effects of Glossary and Read-Aloud Accommodations on English Language Learners’ Performance on a Mathematics Assessment

Glossary and reading aloud test items are commonly allowed in many states' accommodation policies for English language learner (ELL) students for large-scale mathematics assessments. However, little research is available regarding the effects of these accommodations on ELL students' performance. Further, no research exists that examines how students use the accommodations. Using a randomized experimental design and think-aloud procedure, the present study explored the effects of the two accommodations. Results showed no significant effect of glossary, mixed effects of read aloud, and significant interaction effects between students' prior content knowledge and accommodations, which suggests the accommodation was effective for students with content knowledge. Think-aloud data indicated that students were not familiar with, and did not actively utilize the glossary. Implications for the effective use of accommodations and future research are discussed.     

Continuous Professional Development: What Role and Who Benefits? Reflections on Teacher Development in Uganda

Continuous professional development has assumed a central role in organisational development in recent years. In the teaching profession, initial training is no longer seen as enough due to rapid changes in technology, social structures, ideologies and the increasing diversity of the classrooms. While acknowledging the empowering aspect of CPD, this article draws on both literature sources and on an ongoing empirical study on teacher professional integrity to analyse the challenges and opportunities of CPD programmes in Uganda. It also demonstrates a new approach to CPD based on research experiences with the teachers in one school in Uganda.

Who Benefits from the Massification of Higher Education in Taiwan?

The objectives of expanding higher education are to foster advanced personnel and realize the concept of achieving equal access to education. The problems created by the expansion of higher education in many countries, including Taiwan, in fact indicate a divergence from originally anticipated objectives. Such problems include the uneven allocation of resources, tuition differences between public and private schools, and vicious competition in the face of declining student enrollments, all of which contribute to concerns about educational quality issues. Of additional interest is whether Taiwan's focus on university enrollments of disadvantaged ethnic groups has created a trend toward greater educational opportunities for its aboriginal people. Nevertheless, the distribution of resources is increasingly concentrated on elites from high socioeconomic backgrounds and in a few public universities. All of these factors have facilitated an increasing class reproduction in higher education. The original elites continue to enjoy a wealth of resources. Yet while more and more students gain access to higher education, their institutional teaching quality and learning environment still fall behind that of the elites.     

An Evaluation of a Pilot Service‐Learning Course for Criminal Justice Undergraduate Students*

This article focuses on a pilot service‐learning program implemented with undergraduate students enrolled in a juvenile delinquency course. An evaluation of the service‐learning program on students’ attitudes toward diversity, interpersonal skills, personal and intellectual development, and citizenship behavior using qualitative analysis is presented. The results indicate that the majority of students came to view the youth in a positive light, reported learning how to work with youth, experienced a reduction in stereotypes, gained career insights, learned how to apply academic theory to real‐life experiences and developed attitudes about how society addresses delinquency that were sympathetic to the youths’ condition.

Who Is a Good Student?

The junior middle school phase is one in which students first come into formal contact with science subjects and is a key period in the formation of their attitudes toward the sciences. Any setback in science studies in this period inevitably affects the students' studies in the senior middle school phase and even their future choice of specializations and the direction of their career development. Thus science education during the junior middle school phase is of the utmost importance for the students' growth. Studies by scholars abroad show that the great majority of girls have the same intelligence and ambitions as boys when they enter school, but by the time they graduate from junior and senior middle schools they have much less confidence in their abilities and their self-esteem has conspicuously declined. There is also a big difference between boys and girls in terms of their choice of advancement to higher schools, and a relatively small proportion of girls choose to take science courses in senior middle school. In terms of choice of vocations, most girls remain stuck in the narrow field of traditional occupations for females, such as nursing, health care, and secretarial work, and display a clear tendency toward job gender patternization. The rate of school dropouts and discontinued schooling is much higher among girls than boys.¹ Studies by scholars in China show that stereotyped gender impressions among teachers leads to incorrect conduct in education and teaching. For instance, teachers believe that boys are more clever. They make different dispositions for girls' and boys' learning activities, and lavish more attention on boys. Such different feedback to learning information [sic] from boys and girls widens the difference between students of different genders.²     

The Reification of Goal Structures in a Calculus Tutor: Effects on Problem‐Solving Performance

In an initial experiment with a minimal version of a calculus tutor, it was determined through analyses of verbal protocol data that students were attempting to execute a fairly standard working‐backwards, means‐ends strategy to solve systems of equations, but were having difficulty maintaining the requisite goal stack. To remedy this problem, an enhancement to the interface of the tutor was designed which allowed students to post and display the subgoals required by the means‐ends strategy. As students progressed through problems, individual subgoals were boxed and shaded to indicate which subgoals were active and which had been satisfied, respectively.

An experiment testing the effects of this type of goal posting showed that student problem‐solving performance improved in terms of both speed and accuracy while the goal blackboard was present. Furthermore, many of the positive effects persisted after the goal blackboard was taken away.

Two explanations for the beneficial effects of goal posting are offered. The first is that the display served as external memory which maintained goal structures that would have otherwise been lost in the shuffle of problem solving. The second, perhaps more compelling explanation is that, in the process of posting goals, subjects learned something about the underlying structure of problems.     

The Effects of a Chemistry Course with Integrated Information Communication Technologies on University Students’ Learning and Attitudes

The purpose of this study was to evaluate the instructional effects of using animations, static figures, PowerPoint bulletins, and e-plus software as chemistry texts with the aid of computer-based technology. This study analyzed the characteristics of students involved in three multimedia courses and their achievement and attitude toward chemistry and learning chemistry. The three samples included in this study involved 257 undergraduate engineering students enrolled in the courses during the academic year in which the study occurred. The results indicate that: (a) students acquired a better understanding of targeted chemistry concepts during the multimedia courses, (b) some categories of students, based on their major area of study, computer use, and attendance status at orientation achieved significantly (p < 0.05) higher post-test scores when adjusted for pre-test performance, and (c) significant differences and Cohen’s effect sizes in attitudes toward chemistry and learning chemistry were detected for students’ level of computer use, disposition toward computer multimedia, gender, and attendance at the multimedia orientation session. It appears to be helpful to incorporate computer-based multimedia (animations, images, sounds) teaching while utilizing constructivist design principles to facilitate students’ chemistry understanding and attitude toward chemistry and learning chemistry.     

Science and Mathematics Mentees and Mentors: Who Benefits the Most?

The purpose of our study was to determine the extent to which differences in a mentor model for science and mathematics teachers accounted for variances in mentoring effectiveness and persistence rates of teachers. School district designee, mentor, and teacher perceptions of mentoring support were collected through the use of interviews and surveys and analyzed using the grounded theory approach and open coding. Findings revealed that teachers and mentors recommended that future mentor models provide strong support and more face-to-face meetings. The most common change mentors made was that they incorporated new strategies into their teaching. Findings offer insight for structuring mentor models to increase effectiveness and persistence of teachers and build the capacity of mentors.

The Effects of a Flipped Classroom Model of Instruction on Students’ Performance and Attitudes Towards Chemistry

This study establishes the effects of a flipped classroom model of instruction on academic performance and attitudes of 66 first-year secondary school students towards chemistry. A pre-test and post-test experimental design was employed to assign students randomly into either the experimental or control group. In order to assess the suitability of using flipped model of instruction, students were divided in two groups. For the first group called the experimental group, a “flipped classroom” was used in which the students were given video lessons and reading materials, before the class to be revised at home. On the other hand, the second group followed traditional methodology, and it was used as control. The rate of reaction knowledge test and the chemistry attitude scale were administered. In addition, the researcher documented classroom observations, experiences, thoughts and insights regarding the intervention in a journal on a daily basis in order to enrich the data. Students were interviewed at the end of the research in order to enrich the qualitative data also. Findings from this study reveal that the flipped instruction model facilitates a shift in students’ conceptual understanding of the rate of chemical reaction significantly more than the control condition. Positive significant differences were found on all assessments with the flipped class students performing higher on average. Students in the flipped classroom model condition benefited by preparing for the lesson before the classes and had the opportunity to interact with peers and the teacher during the learning processes in the classroom. The findings support the notion that teachers should be trained or retrained on how to incorporate the flipped classroom model into their teaching and learning processes because it encourages students to be directly involved and active in the learning.
