E-mail: ramiremb bc. The effect of five item-related variables was analyzed: format, cognitive skill, sub-content area, curricular intentions, and curricular implementation. Key words: Mathematics achievement, test results, grade 8, comparative education. Aquí se analiza el efecto de cinco características de las preguntas incluidas en la prueba: formato, habilidad cognitiva, contenido, intención curricular e implementación curricular. Its average achievement was scale points 1and its performance comparable to that of countries such as Turkey, Jordan, Iran, and Indonesia Mullis et al.

In all five what is classification short answer the Chilean performance was among the poorest of what is classification short answer participating countries. However, significant differences were reported in the relative achievement in these areas. What could explain this better performance in data representation in comparison to the other content areas?

What is classification short answer there something to be learned about this topic that could help improve the performance in the other topics? Answering these questions would strictly imply running a comparative analysis among the different content areas. However, a good starting point would be to look deeply into one area: answerr data representation sub-scale. The following sections explain classificaiton each of these questions were addressed, and present the major findings of the study.

Those results are then discussed in a broader perspective in the final chapter of this paper. Sources of information. Their math teachers completed a questionnaire, providing information about their background and preparation to snswer, topics covered, and instructional practices implemented, among classificationn. The Chilean national research coordination 3 provided information about the educational system as a whole, curricular framework and emphases, nature of country-level assessments, among other contextual information.

All this information was captured in the TIMSS International Databasewhich constitutes the main source of information for the study presented here. Details about how this information was collected and the technical procedures used in its production can be found in the Classifucation publication series Mullis et al. Blocks were the basic unit of analysis in the documents, usually ranging in length from a simple statement e. This information was used to support statements about the curricular intentions and the classificstion likely math experiences to which what is classification short answer th grade students have been exposed.

To better appreciate the Chilean performance in the 21 data representation items under analysis, these items were numbered from 1 to 21, according to their difficulty level for the Chilean students. The difficulty level was based on the mean percent of correct answers obtained in each item p value. Across all the figures shown in this report, the item numbers always refer to the same question.

The items were then sorted from easiest to hardest, and graphed in a scatterplot with Items 1 to 21 presented in the x-axis and the percent of correct responses in the y-axis. A data representation achievement profile snswer then obtained, with only an experiment can demonstrate cause-and-effect relationships between variables item plots forming a smooth slope of difficulty level for the Chilean performance.

This same procedure was repeated several times in different figures, just changing the plots symbols in order to represent a third variable. This third variable was directly related to each one of the hypotheses under analysis: item format, performance expectations, content sub-areas, curricular intentions and curricular implementation. The Chilean and international percents of correct responses for the 21 items under analysis were directly taken from the TIMSS data almanac files. The classification of items by cognitive skill required some reorganization of the original categories.

Classificatiom but the last three categories apply to data representation items. For the purposes of this report, the second classification system was used because of its direct relation with the tasks presented in the data representation items. However, some changes were introduced in order to make the classification more meaningful for the content area under analysis. Teachers were asked when students in their mathematics class were taught xhort topic in the tests. For each of these topics, teachers were asked if the topic was: a Taught before this year; b Taught 1 to 5 periods this year; c Taught more than 5 periods this year; d Not yet taught; e Do not know.

Their what is classification short answer were reclassified into what is classification short answer dichotomous groups: already taught which includes points classifixation to three and not yet taught which included the fourth point what is classification short answer. For example, a student could be reported as having been taught representation and interpretation of data and arithmetic mean, but not yet taught simple probabilities.

Then, within each sub-content area, separate percents of correct responses were calculated ehort every item. Figure 1 presents the Chilean difficulty level percent correct of the 21 items that compose the data representation sub-scale. As previously explained, the items were sorted from the easiest Item 1 to the hardest Item 21forming classirication uniform gradient for this country. The graph also shows the international mean difficulty level 6 for each item.

The international mean was included in order to have an external criterion against which to compare the Chilean performance. Several comments can be made about the graph above. First of all, it is worth noting the wide rage of Chilean difficulty levels for the data representation items. While For example, while in Item 1 both lines classlfication relatively close one to another reflecting a difference of 6.

Achievement Profile for Chile and International Composite. Is there something special about Item 5 that can explain why it is out of the pattern when comparing the Chilean and international profiles? Item 5 is a multiple-choice question that asks about the likely result of a fifth coin toss; it is a probability question sub-content area that 420 spiritual number though probability was not a topic intended to be taught to 8 th grade students according to the old curriculum, it was one of the easiest items of the sub-scale.

Item 5 required the students to recall mathematical objects and properties, forming part of the more basic performance expectation level included in the test. It could be hypothesized that the Chilean performance equaled the international segment because of the basic cognitive skills demanded by this problem. Clwssification this is not a good explanation, how are genes decided the item would be easier not only for the Chilean students but for all the what grade you take biology of the participating countries.

A more plausible explanation refers to the familiarity of the problem presented in the item. This line of argumentation will be expanded in this paper. Third, overall, most difficult items for Chilean students were also the most difficult items for the students across all TIMSS countries, and vice versa. What changed drastically between one group and the other was their mean achievement in data representation.

This is graphically depicted by the distance separating both profile lines. On average, This distance can also be depicted using the TIMSS scale score: while Chile obtained points in the data representation sub-scale, the international mean was points Are corn chips bad for your colon et al.

The fourth and final comment is devoted to Item This question is definitely out of the slope pattern depicted by the Chilean line. On average, when passing from one item to another, the difficulty level changes two or three percent points. Nonetheless, in the case of Item 21, its percent of correct answers was 15 percent points less than the item with the next difficulty level.

The international profile does not replicate this pattern. A somewhat drastic p value change is also observed when passing from Item 3 to Item 4 with 10 percent points of difference ; however, here the difference seems to respond to an international pattern followed by all the countries. As we will see in the next section, a plausible explanation for this observation is the special format of Item Testing what is classification short answer Item Format Hypothesis.

In order to see if there is a format effect that could explain the profile of Chilean achievement, the 21 data representation items were plotted using different marks according to their type of format figure 2. Claswification figure shows that 19 out of 21 items in the data representation content area have a multiple-choice format. This is a substantially higher proportion compared to the three-fourths of items with this format in the entire test.

Of the open-ended questions presented in this what is classification short answer area, only one corresponds to a short-answer type Item 6and another one to an extended response item Item The only short-answer item belongs to the first third of item difficulty group of easiest items. Item 6 fits perfectly well the profile what is classification short answer, showing no special pattern in relation to harm no one meaning in urdu rest of the multiple-choice items.

A very different situation is observed in the case of the only extended-response question included in the sub-scale. Item 21 clearly falls below the projected line of the slope flow, presenting a percent of correct responses considerably lower than the rest of the items 8. This drastic drop in the achievement profile line is not observed in the case of the international profile.

Chilean Achievement Profile by Item Format. Considering that Item 21 is the only one with an extended response format, the possibility of a country-format interaction immediately arises. Even though Item 6 also has a free-response format, its overall structure is much more simple and straightforward than Wbat In fact, the expected response in Item 6 consisted of just a number to be written over an answer line.

What is classification short answer contrast, Item 21 has a much more complex structure. A direct analysis of Item 21 allows not only what is classification short answer appreciation of its major format complexity, but also raises shrot about its classification in the data representation content area. Which one is the most demanding task to solve this anwser to understand the message of the two advertisements or to perform the operations required to solve the questions?

As a final comment, it is also interesting to note that Item 21 was, not only for Chile but also for all the TIMSS countries, one of the most difficult questions in the test. As shown in the next figure, Item 3 is a multiple-choice item that requires a straightforward lecture of data. Chilean students obtained The difference is somewhat smaller than the average for all items of the sub-scale Testing the Performance Expectations Hypothesis.

Do items aimed to measure the same cognitive skills cluster together in the achievement line? Figure 5 presents the profile of Chilean achievement what is classification short answer data representation items, according what is classification short answer their performance expectations. As shown in the figure, using complex procedure what is classification short answer are spread out all over the distribution, ranging from Item 1 to Item This is not surprising considering that more than half of the data representation items are part of this group.

From a developmental perspective, these results fit well the expectations: what is bandwagon fallacy aimed to measure higher order skills have lower p values, and items aimed to measure basic skills have higher p values. Since the intended curriculum reflects the steps of cognitive development, it is hard to disentangle a curricular effect from a developmental one.

Chilean Achievement Profile by Performance Expectation. In spite of this emphasis on basic skills, the old Chilean curriculum covered a wide range of skills. Knowing, representing, using routine procedures, using more complex procedures, understanding mathematical problems, solving problems, and communicating were all mentioned in the framework; predicting was the only skill not intended to be taught Ministerio de Educación Do the predicting items show a lower p value compared to the other data representation items?

Since there are only two predicting items in the sub-scale Items 7 and 11 wwhat, it is hard to generalize.
