Time To Change the Bathwater: Correcting Misconceptions About Performance RatingsGorman, C. Allen, Cunningham, Christopher J.L., Bergman, Shawn M., Meriac, John P. 04 July 2016 (has links)
Recent commentary has suggested that performance management (PM) is fundamentally “broken,” with negative feelings from managers and employees toward the process at an all-time high (Pulakos, Hanson, Arad, & Moye, ; Pulakos & O'Leary, ). In response, some high-profile organizations have decided to eliminate performance ratings altogether as a solution to the growing disenchantment. Adler et al. () offer arguments both in support of and against eliminating performance ratings in organizations. Although both sides of the debate in the focal article make some strong arguments both for and against utilizing performance ratings in organizations, we believe there continue to be misunderstandings, mischaracterizations, and misinformation with respect to some of the measurement issues in PM. We offer the following commentary not to persuade readers to adopt one particular side over another but as a call to critically reconsider and reevaluate some of the assumptions underlying measurement issues in PM and to dispel some of the pervasive beliefs throughout the performance rating literature.

Assessing and Improving Student Understanding of Tree-ThinkingKummer, Tyler A. 01 March 2017 (has links)
Evolution is the unifying theory of biology. The importance of understanding evolution by those who study the origins, diversification and diversity life cannot be overstated. Because of its importance, in addition to a scientific study of evolution, many researchers have spent time studying the acceptance and the teaching of evolution. Phylogenetic Systematics is the field of study developed to understand the evolutionary history of organisms, traits, and genes. Tree-thinking is the term by which we identify concepts related to the evolutionary history of organisms. It is vital that those who undertake a study of biology be able to understand and interpret what information these phylogenies are meant to convey. In this project, we evaluated the current impact a traditional study of biology has on the misconceptions students hold by assessing tree-thinking in freshman biology students to those nearing the end of their studies. We found that the impact of studying biology was varied with some misconceptions changing significantly while others persisted. Despite the importance of tree-thinking no appropriately developed concept inventory exists to measure student understanding of these important concepts. We developed a concept inventory capable of filling this important need and provide evidence to support its use among undergraduate students. Finally, we developed and modified activities as well as courses based on best practices to improve teaching and learning of tree-thinking and organismal diversity. We accomplished this by focusing on two key questions. First, how do we best introduce students to tree-thinking and second does tree-thinking as a course theme enhance student understanding of not only tree-thinking but also organismal diversity. We found important evidence suggesting that introducing students to tree-thinking via building evolutionary trees was less successful than introducing the concept via tree interpretation and may have in fact introduced or strengthened a misconception. We also found evidence that infusing tree-thinking into an organismal diversity course not only enhances student understanding of tree-thinking but also helps them better learn organismal diversity.

The neglect of cities in the missionary work of the Reformed Churches in Southern Africa with special reference to churches of Synod Soutpansberg / by Muswubi Takalani AaronMuswubi, Takalani Aaron January 2007 (has links)
This research reviewed the neglect of cities in the mission work of the Reformed Churches in Southern Africa with a special reference to churches of Synod Soutpansberg. The biblical passage, Jeremiah 29:1-14 was used, as a representative of other biblical passages, to shed light on the role of cities in mission work of the church while addressing misconceptions and false theology about the cities and the role they played and still play in the mission work of the church. The same biblical message is confirmed by many missiology literature, including, "Cities, Missions' New Frontier" by R.S. Greenway and T.M. Monsma (1989); "City of God - City of Satan" by R.C. Linthicum(1991) and "Discipling the City" by R.S. Greenway (1992). The biblical message and the missiology literature mentioned above were the basis from which the neglect of the role of the cities in the history of the mission work of the Reformed Churches in Southern Africa was studied. From these basis, the causes, implementations and effects of such neglect in the mission work of the Soutpansberg churches was studied in Chapter 3. The empirical research was conducted using the interview questionnaire in Chapter 4. The empirical results and findings, which were presented in this research, can direct churches towards a remedy of the neglect of the cities in their mission work as far as the strategies is concerned. The neglect of the cities in the history of the mission work of the Reformed Churches in Southern Africa was studied with an aim that churches learn from it and hence avoid the past neglect in their present and future mission plans, strategies and programs. In other words, the lesson is important for churches to view the role of the secular cities as important instruments used by God to speed up not only the planting and growing big holy churches from those secular cities outwards, but also the biblical reformation of the rural - orientated theories, strategies and practice! / Thesis (M.A. (Theology))--North-West University, Vaal Triangle Campus, 2008.

Overcomming Misconceptions in Religious Education: The Effects of Text Structure and Topic Interest on Conceptual ChangeKing, Seth J. 01 May 2013 (has links)
The aim of this study was to quantitatively measure refutation text's power for conceptual change while qualitatively discovering students' preference of refutation or expository text structures. This study also sought to examine if religious interest levels predict conceptual change. Participants for this study were 9th, 10th-, 11th-, and 12th-grade seminary students from the private religious educational system of The Church of Jesus Christ of Latter-day Saints (LDS). The study was conducted in two sessions. Session 1 involved pretesting, interventions, and posttesting. Session 2 involved delayed posttesting and participant interviews. Results were predominately measured quantitatively with some qualitative interview analysis added to enrich the study. This research study provides insight into the refutation text effects in LDS religious education. Results of the study showed significant differences in conceptual change between participants reading refutation texts and those reading expository texts. In every case, the refutation text group performed higher on posttests than did the expository group. Results also showed participant preference toward refutation text structures. Furthermore, the study found significant correlations that verify topic interest as a possible predictor of conceptual change. Insights are valuable in aiding curriculum developers in implementing effective ways to teach doctrinal principles by utilizing refutation text interventions. The advantages of this research study add to educational research and identify areas for improvement and exploration in further research. This study of refutation text effects in religious education also broadens researchers' understanding of refutation text's power for conceptual change in subjects outside of K-12 science. Results of this study are of interest to researchers, teachers, curriculum writers, and LDS seminary teachers and administrators.

Test items for and misconceptions of competences in the domain of logic programmingLinck, Barbara January 2013 (has links)
Development of competence-oriented curricula is still an important theme in informatics education. Unfortunately informatics curricula, which include the domain of logic programming, are still input-orientated or lack detailed competence descriptions. Therefore, the development of competence model and of learning outcomes' descriptions is essential for the learning process in this domain. A prior research developed both. The next research step is to formulate test items to measure the described learning outcomes. This article describes this procedure and exemplifies test items. It also relates a test in school to the items and shows which misconceptions and typical errors are important to discuss in class. The test result can also confirm or disprove the competence model. Therefore, this school test is important for theoretical research as well as for the concrete planning of lessons. Quantitative analysis in school is important for evaluation and improvement of informatics education.

Comparing the Effect of Reflections, Written Exercises, and Multimedia Instruction to Address Learners’ Misconceptions Using Structural Assessment of KnowledgeSarwar, Gul Shahzad 18 May 2012 (has links)
The study assessed the knowledge structure of Grade 11 physics students and their instructors using Pathfinder networks. Instructors’ structural knowledge was averaged to create a referent pathfinder network. Each student’s pathfinder network was compared with the referent pathfinder network in order to identify misconceptions. These misconceptions served as the basis for remedial instruction. The study was conducted in six sections of Grade 11. Three different types of remedial instruction based on three different chapters from the Grade 11 physics textbook were given to the students at three separate stages. In the first section, students were shown their own and referent pathfinder networks as an intervention during the first stage. The students were asked to reflect on the similarities and differences between them. The researcher gave written concept-oriented exercises based on the differences at the second stage, and multimedia concept-oriented instruction based on the differences was given to the students at the third stage. The order of instruction was counterbalanced in all the six sections. After each stage, students’ pathfinder networks were reassessed and the similarities between students’ and the referent pathfinder networks were calculated to measure the effect of a particular intervention. The study tried to determine which type of remedial instruction given to students best improved the knowledge structure of the students in the domain of physics. Results revealed that the similarity indices around the treatment concepts in the pathfinder networks of the students increased the most from pre- to post-intervention phase because of their reflections, followed by multimedia concept-oriented instruction and written concept-oriented exercises. Most likely, the major reason for this change was the interventions around the treatment concepts by the researcher at three different stages which stimulated and probably changed some of students’ misconceptions. To address the issue of validity, the similarity indices of control concepts in the students’ pathfinder networks were also checked for improvement. The result shows that there is no appreciable improvement in control concepts as there was no intervention around those concepts. Findings support the use of structural assessment of knowledge with pathfinder scaling technique to check the effectiveness of a classroom instruction.

Implementation Of Conceptual Change Oriented Instruction Using Hands On Activities On Tenth Grade StudentsIpek, Inciser 01 February 2007 (has links) (PDF)
The purpose of this study was to compare the effectiveness of the conceptual
change oriented instruction using hands-on activities and traditionally designed
chemistry instruction on 10th grade students&rsquo / understanding of gases concept. Also,
the effect of instruction on students&rsquo / attitude toward chemistry as a school subject
was investigated. The sample of the study consisted of 59 tenth grade students from
two chemistry classes in a public high school. This study was conducted during the
2006-2007 fall semester. The classes were randomly assigned as control and
experimental groups. Students in the control group were instructed by traditionally
designed chemistry instruction whereas students in the experimental group were
instructed by the conceptual change oriented instruction accompanied with hands-on
activities. Gases concept test and Attitude Scale Toward Chemistry were
administered to both groups as a pre-test and post-test to assess the students&rsquo / understanding of gases concepts and to determine their attitudes toward chemistry,
respectively. Science Process Skills Test was given only at the beginning of the
instruction to determine students&rsquo / science process skills.
v
The hypotheses were tested by using multivariate analysis of variance
(MANOVA). The post-test results showed that conceptual change oriented
instruction using hands-on activities caused a significantly better acquisition of
scientific conceptions related to gases concept. But it was found that treatment has
no significant effect on students&rsquo / attitudes toward chemistry as a school subject.

Using Technology In Preventing And Remedying Seventh Grade Students' / Misconceptions In Forming And Solving Linear EquationsErek, Gorkem 01 May 2008 (has links) (PDF)
The purposes of this study was to investigate seventh-grade students&rsquo / misconceptions related to forming and solving equations and examine the role of technology use in preventing and remedying these misconceptions. A group of 18 seventh grade students was given a diagnostic test before they started the equations unit to determine their misconceptions related to the topic. Students studied equations for 6 weeks and half of the instruction took place in the computer lab where they used various electronic manipulative and activities on the computer. The students were given another diagnostic test at the end of the instruction. After a month, they took another diagnostic test for the third time. The diagnostic tests were equivalent to each other in terms of item structures and contents. The effect of technology use in changing students&rsquo / performances on the diagnostic tests was determined by repeated-measures ANOVA. Furthermore, changes in students&rsquo / misconceptions were also analyzed qualitatively. According to the results, no significant effect of technology use on preventing and remedying misconceptions was found. However, technology positively affected students&rsquo / feelings, thoughts and attitudes towards equations. Outcomes of this study have some implications for teachers, teacher educators, and curriculum writers as solving and forming equations is fundamental for learning algebra and a very significant strand of school mathematics.

Secondary School Students’ Misconceptions in AlgebraEgodawatte Arachchige Don, Gunawardena 30 August 2011 (has links)
This study investigated secondary school students’ errors and misconceptions in algebra with a view to expose the nature and origin of those errors and to make suggestions for classroom teaching. The study used a mixed method research design. An algebra test which was pilot-tested for its validity and reliability was given to a sample of grade 11 students in an urban secondary school in Ontario. The test contained questions from four main areas of algebra: variables, algebraic expressions, equations, and word problems. A rubric containing the observed errors was prepared for each conceptual area. Two weeks after the test, six students were interviewed to identify their misconceptions and their reasoning. In the interview process, students were asked to explain their thinking while they were doing the same problems again. Some prompting questions were asked to facilitate this process and to clarify more about students’ claims.
The results indicated a number of error categories under each area. Some errors emanated from misconceptions. Under variables, the main reason for misconceptions was the lack of understanding of the basic concept of the variable in different contexts. The abstract structure of algebraic expressions posed many problems to students such as understanding or manipulating them according to accepted rules, procedures, or algorithms. Inadequate understanding of the uses of the equal sign and its properties when it is used in an equation was a major problem that hindered solving equations correctly. The main difficulty in word problems was translating them from natural language to algebraic language. Students used guessing or trial and error methods extensively in solving word problems.
Some other difficulties for students which are non-algebraic in nature were also found in this study. Some of these features were: unstable conceptual models, haphazard reasoning, lack of arithmetic skills, lack or non-use of metacognitive skills, and test anxiety. Having the correct conceptual (why), procedural (how), declarative (what), and conditional knowledge (when) based on the stage of the problem solving process will allow students to avoid many errors and misconceptions. Conducting individual interviews in classroom situations is important not only to identify errors and misconceptions but also to recognize individual differences.
